From Shaanxi Heavy Duty Truck Company, which set a new record for the highest power of domestic trucks, to Liaocheng Company, which took the lead in laying out the new energy bus product line with hydrogen fuel cells, to Yangzhou Company, which is deeply involved in the high-end commercial highway passenger transport market, Chai Weiyaxing Commercial Vehicle Company, a subsidiary of Wei Chai Yangzhou Company, has not gained much with the overall blessing of key components such as Hande axle, quick gearbox and Zhongshan leasing financial solution. The two YBL659 1 RVs that came to participate in this exhibition were named "Land Business Class", but at the product launch conference of Wei Chai Yangzhou Yaxing Commercial Vehicle Company (hereinafter referred to as "Yaxing Commercial Vehicle"), due to the limitations of product strength and distribution network, this model has never been widely promoted; As the main vehicle type in the field of highway passenger transport in Shang Ya, YBL675 1 series long-axle high-top "Ourui" highway buses did not appear in this business meeting.

The author was lucky enough to attend the 20 18 annual meeting of Asian business circles, and established a preliminary understanding of YBL675 1 series, the main vehicle in the field of highway passenger transport. From the end of 18 to the beginning of 19, we tracked the market and products of this vehicle series, and combined with the fragmentation and segmentation of China highway passenger transport market under the impact of other parallel modes of transportation such as high-speed rail, we summarized the following contents.
The origin of 7.5m Wei Chai Euromonitor medium-sized bus.
Wei Chai Yangzhou Yaxing Commercial Vehicle Company, whose predecessor was Yaxing-Benz Co., Ltd., was established in March 1997. As the earliest joint venture case in China bus market, the marriage between Yaxing and Mercedes-Benz ended in failure, but its topicality and reference significance still have a far-reaching impact on the reform and development of China bus industry today. In 2007, after Yaxing-Benz finally entered history and changed its name to Yaxing Commercial Vehicle Company, although Yaxing launched its own YL6123 series of high-end road buses, it finally stopped the launch of the whole vehicle during the adjustment of the product section of Yaxing Bus Co., Ltd. (hereinafter referred to as "Yaxing Bus Co., Ltd."), and the road bus business was merged into its subsidiary shares instead of providing parts for the subsidiary shares.
2065 438+03- 10, Weichai Power and Yangzhou Yaxing reached a strategic cooperation, including stock splitting, sub-business, Yangchai and other sectors, and even a Yangzhou Sheng Da special purpose vehicle company specializing in the modification of special purpose vehicles. Wei Chai Yangzhou Plate has officially become a multi-functional and highly integrated automobile industry organization, and many of its brands have also moved into Huaisi Town Automobile Industrial Park in Hanjiang District, the northern suburb of Yangzhou on 20 15 1.
Eurasian YBL675 1 Medium Bus
After Wei Chai became the boss of Yaxing, he made great adjustments to Asian businessmen, making it possible to realize vehicle manufacturing again. In, highway passenger transport has reached the end of its development, and the market is weak. Wei Chai's idea is to deal with the road bus market under the impact of high-speed rail passenger flow by miniaturization and commercialization, and to launch low-cost solutions suitable for business trips in time to establish the brand of Euromonitor. After the reverse development of the 6-meter class bus in advance and the verification in recent two years, Shang Ya finally chose the 7.5-meter class bus, and launched a YBL675 1 series "Euromonitor" medium-sized road bus suitable for miniaturization of road passenger transport.
Characteristics of diesel YBL675 1 medium-sized highway buses
YBL675 1 "Euromonitor" bus, located in medium-sized highway passenger transport, is a solution to adapt to the current situation of highway transportation and give consideration to cost control. Traditional medium-sized highway passenger transport is mainly composed of business travel and rural passenger transport. In recent years, the highway passenger flow has been narrowing, and the passenger demand of 10-25 intercity highway is outstanding. Because it is necessary to basically ensure the basic service level of passenger vehicles, it is different from rural passenger transport with similar capacity in appearance, interior decoration and driving comfort. In the end, Asian merchants chose the body length of 7.5m, built a long-headed and load-bearing road bus with light passengers as the main body, and officially launched YBL675 1 "Euromonitor" road bus to the market in 20 16.

In view of the rigid requirements for seat spacing and luggage compartment volume in the current rating standards for medium-sized and advanced vehicles, the long-axis Euromonitor determined the body length of 7.5 meters at the beginning of research and development, which is the largest among similar models of the same class and structure. YBL675 1 Based on the load-bearing body, the side luggage compartment structure of the traditional road passenger car cannot be realized due to the height limitation of the skeleton and floor. In recent years, the luggage compartment is set at the rear of the vehicle, and the last row of seats moves forward. This arrangement can still meet the rating requirements, which is also the key to the advantage of 7.5m body length.
Chai YBL675 1, prototype with dual-mass flywheel.
According to the product layout of Wei Chai, YBL675 1 has been the standard engine of Chai Weiyang boat since it was launched. In 20 19, the original RA425 configuration was upgraded. At present, the 2.8l displacement RA428 engine is already a standard engine. However, in terms of power output, RA428 has no obvious data improvement compared with RA425, but the larger displacement effectively broadens the torque matching range of power output, which can bring better fuel economy when applied to high-speed working conditions. Through road test and customer feedback, the comprehensive fuel consumption of YBL675 1 is between 10- 12L.
Engine compartment, equipped with Wei Chai RA428 engine.
Wei Chai Yangzhou RA series engine comes from Wei Chai Yangzhou Diesel Engine Factory, which is a high-end light diesel engine developed by Italian VM technology. SAIC SC25/28R series, which also adopts VM technology, has been widely used in similar vehicles for a long time and has a good response at present. RA series engines adopt Bosch high-pressure common rail technology to achieve a wider fuel consumption range to provide better economy. In theory, better NVH and smaller engine volume are achieved by adopting cylinder liner-less cylinder block and double overhead camshaft. However, in the past two years, the fuselage jitter of YBL675 1 model with RA425 series is still serious. Asian merchants finally had a solution at the end of 20 18. Since the vehicles delivered at the end of last year, the original single-mass flywheel of the engine has been upgraded to a dual-mass flywheel, which has been well improved.
Instrument table
The light gearbox products of Zhuzhou Gear Factory, a subsidiary of Fast Gearbox, are adopted. The front axle and rear axle are from Liaoning Shuguang and Shenyang CRRC respectively. Similar to most long-headed medium-sized buses of the same class, the front axle is McPherson independent suspension, and the rear axle is equipped with multiple steel plate suspensions as standard. The curb weight is about 3.5 tons, and the smaller body weight benefits from the load-bearing body structure, which also determines its good power output and fuel economy.
Three-way surrounding headrest seat
However, the limitation of the body structure also determines that the car is not suitable for rural passenger transport with heavy load and high passability, and the luggage compartment needs to be set on the side, so its application scope is limited. I have consulted the relevant staff of Asia Merchants, and I got a negative answer about whether Wei Chai Euromonitor can launch a medium-sized bus with traditional vertical longitudinal beam chassis structure in the future, and expand its application scope through this low-cost scheme to compete with products in the same field. It also indicates that if similar body structures continue to adopt the same or similar power matching mode, it will lead to a sharp increase in fuel consumption and insufficient power, and it is necessary to completely subvert the power configuration of the whole vehicle. At the same time, this design based on the traditional medium-sized bus architecture has gone beyond the business scope of the sub-business, and the decision-making power should be in the sub-shares. Need regional molecular products and sub-products to avoid internal competition.

At the same time, according to JTT 1094-20 16 operation standard, Shang Ya has further upgraded YBL675 1 series models. Euromonitor not only welcomes ESC standards, but also upgrades flame retardant materials and interior panels. Recently, according to the experience of previous models in Yunnan-Guizhou Plateau, YBL675 1 series has also completed the trial installation and successful verification of retarder, further broadening the applicable environment and road conditions of the models.

Chai conforms to the process of fragmentation and miniaturization of highway passenger transport. In fact, it is to gradually absorb customer feedback, expand the application scope of vehicle models, and further offset the miniaturization of highway passenger transport. Different from the appearance of short-axle long-headed cars a few years ago, the appearance of YBL675 1 really replaced the original 10-20 passenger bus line. In addition, similar vehicles such as Hagrid H7V have gradually gained higher exposure during the replacement of operating vehicles in recent years. At the time of R&, the emergence of many competitive products also enriched the product selection at this level, and the more active R & ampd concept is gradually moving towards the mainstream market.
YBL675 1 medium bus has been delivered.
Take Yutong CL6/7 as an example. This product, which was launched one year after the launch of Euromonitor, is almost the same as Euromonitor series in terms of power configuration and length. Recently, it was announced that the original VM2.8T engine of Shanghai diesel engine would be expanded, and the RA428 series of Shanghai diesel engine was officially provided for selection. Although the parameters seem to be close, in fact, as a model of the same class built on the basis of the traditional non-loaded body (straight longitudinal beam chassis), it is similar to Euromonitor only in appearance and size, but completely different in essence. Yutong CL series adopts traditional non-load-bearing structure. Due to the change of chassis height and structure, with side luggage, the passability is better. But the weight of the whole vehicle is bound to increase greatly. The weight gain of 0.8 tons actually means that the weight gain of CL series reaches 20%-25%, and the most obvious influence is the drastic change of fuel consumption. At the same time, in order to match the same type of engine with larger body weight, CL series also adopts a high torque and faster gearbox different from Euromonitor to improve power performance.
Application case
Since its launch, diesel-European YBL675 1 series vehicles have been steadily popularized in some operating lines, forming several representative typical cases. Take Wuhu-Maanshan "Wuma Bus Rapid Transit" project of Wuhu Yuntai Group as an example.
Wuhu to Maanshan is the middle section of Ning 'an (Anqing) high-speed railway. At present, Ning 'an high-speed railway is in a normal and commuter operation situation, and the highway passenger flow is irreversibly impacted, making it difficult for the highway passenger transport industry to find a way out. In recent years, Wuhu Yuntai Group has updated the vehicles on this line, newly purchased 20 YBL675 1 Euromonitor models for the operation of this line, and established a new brand "Wuma Bus Rapid Transit". The vehicle will start water circulation at Liangcheng Bus Terminal for 30 minutes to 1 hour. Due to the close distance between the two cities, the whole route of the vehicle is from Wuhu to Maanshan on Ningwu Avenue, which can provide customized services for passengers along the way. Because both cities are big cities in Anhui Province, the road conditions are good, and even if you don't take the expressway, you can complete the trip within one hour, and the experience is good. At the same time, both new cars and newly developed brands pass through the main areas of the two cities, which not only promotes the concept of business travel, but also has better brand promotion effect.
Wumate express bus
In recent years, under the severe impact of the environment, Wuma BRT has achieved good economic benefits. The one-way ticket price is within 20 yuan, the attendance rate is between 50% and 75%, and the total revenue of single operation is between 1000- 1500 yuan. However, due to the short driving distance, good road conditions and low comprehensive fuel consumption of vehicles, the fuel consumption expenditure of a single operation is only about 50 yuan, and there is little pressure for the operation to achieve profitability. At the same time, we gain good brand influence, provide differentiated and commercialized services and more customized choices.

Some application cases: Shanghai, Heilongjiang, Jilin, Guizhou, etc
Facing the grim situation of the current highway passenger transport market, the possibility of passenger transport recovery in a short time in the future is low, and it is actually a top priority to achieve higher-end differentiated services through lower costs. At the 20 18 Weichai Power Business Conference, Yashang also put forward the irreversible signal of miniaturization of highway passenger transport. Shang Ya and Yagu are the passenger car manufacturers of Weichai Power Yangzhou Plate, and the layered and discrete passenger car product line realized through mutual cooperation is particularly important for the overall development of Weichai Power Bus Plate.
In fact, Euromonitor is not an excellent product with distinctive features, but its purpose is to provide reasonable solutions for the use cost and capacity allocation in the fragmented environment formed by the high-speed rail network after the sharp drop in passenger traffic on expressways, and there are some typical cases. In the future, more similar products will enter the domestic high-speed passenger transport stage through active research and development. Today, the situation is difficult to reverse, and how to choose and develop passenger transport products in the next step is worth continuing.
