How to disassemble and assemble Changan Suzuki Alto starter (how to open the hood of Changan automobile)
The switch of the midrange hood is designed on the left side of the clutch. Open the main driving door, find the hood switch and pull it back. At this time, you can see the hood pop up, and then put your hand into the gap where the hood pops up and open it.
Functions of the alto cover:
1. Air-air shunt: For an object moving at high speed in the air, the air resistance and turbulence generated by the airflow around the moving object will directly affect the motion trajectory and speed. The shape of the hood can effectively adjust the direction of airflow relative to the car and the blocking force to the car, thus reducing the impact of airflow on the car.
2. Protect the engine and surrounding pipe fittings, etc. Under the hood, it is an important part of the car, including engine, circuit, oil circuit, braking system and transmission system. By improving the strength and structure of the engine hood, adverse effects such as impact, corrosion, rain and electrostatic interference can be fully prevented, and the normal operation of the vehicle can be fully guaranteed.
3. Assisted driving vision. In the process of driving a car, forward-looking and natural light reflection are very important for drivers to correctly judge the road surface and the situation ahead. The direction and form of reflected light can be effectively adjusted by the shape of the hood, thus reducing the influence of light on the driver.
4. Prevent accidents. The engine works in high temperature and high pressure flammable environment, and there are accidents such as explosion, combustion and leakage due to overheating or accidental damage of original parts. The hood can effectively block the damage caused by the explosion and play the role of a protective cover. Effectively block air, prevent flame from spreading, and reduce combustion risk and loss.
5. Dedicated platform. In special vehicles, the high-strength hood plays a supporting role as a working platform.
How to assemble and disassemble Changan Suzuki Alto starter (how to replace the new Alto front wheel bearing)
First, tap the claw of the photosensitive drum remover to loosen the dust cover from the fixed position. Then unscrew the bolt and fix the guide pin with a wrench. Then remove the caliper housing and fix it on the body with steel wire. Finally, remove the brake disc, screw out the wheel bearing hub with the angle self-locking nut of 12, and then pull out the wheel bearing with the tensioner.
Hub bearing is an important part of tire, which can bear axial load and radial load. It is mainly used to bear the load and provide accurate guidance for the rotation of the hub.
In the domestic market, there are two main types of central two-stage drive axle: one is the design of truck rear axle, such as Eaton series products, which reserve space in advance in single-stage reducer. When the traction and speed ratio need to be increased, a cylindrical planetary gear reduction mechanism can be installed, and the original central single-stage is changed into a central double-stage drive axle, so that the three-stage (that is, serialization, generalization and standardization) transformation degree is high and the axle housing is high.
Due to the difference of manufacturing accuracy and material uniformity, even if the same batch of bearings with the same material and size are used under the same working conditions, their service life is different. If the statistical life is 1 unit, the longest relative life is 4 units and the shortest is 0. 1-0.2 units, and the ratio of the longest life to the shortest life is 20-40 times. 90% of bearings do not produce pitting corrosion, and the number of revolutions or hours experienced is called the rated life of bearings.
