1, which makes the vehicle have good adaptability.

When the hydraulic torque converter is installed behind the engine, the torque on the output shaft of the torque converter can be increased several times than that of the engine, and the speed can be reduced to zero. When the external road resistance changes, the hydraulic torque converter can automatically change the traction of the vehicle accordingly to meet the requirements of resistance change.

2. Improve the passing performance of vehicles.

Because the vehicle or crawler traveling device can travel at any small speed and the traction force is stable, the adhesion ability between the traveling device and the ground is improved, and the passing performance of the vehicle on soft roads, mud, sand, snow and other roads is improved.

3. Improve the service life of vehicles.

Because hydraulic transmission relies on liquid to transfer energy, it can absorb the vibration and impact of engine and external load, and there is no mechanical wear between transmission elements, thus improving the service life of vehicles.

4. Improve the comfort of the vehicle.

The hydraulic torque converter has the ability of stepless continuous speed change and torque change, and has good automatic adjustment and adaptability to external loads. Make the vehicle start smoothly, accelerate quickly and evenly, and improve the ride comfort.

The disadvantages of hydraulic transmission compared with mechanical transmission;

1, low efficiency

The efficiency of hydraulic transmission components ranges from zero to the highest efficiency. Relative gear transmission is inefficient and economical. Hydraulic torque converter has the problems of low efficiency and limited torque range.

2, the structure is complex

Hydraulic transmission components have complex structure, large volume and weight, difficult parts processing, high production cost and troublesome maintenance.
