Hydraulic transmission system of internal combustion engine car generally include a hydraulic transmission box, universal shaft, axle gear box three parts. Shunting locomotive sometimes including a condition gear box, the parts are equipped with a number of rolling bearings.
1. Hydraulic transmission boxes bearing
Hydraulic transmission box way of working is in traction train, through the hydraulic change is the power of diesel engine and will be converted to drive locomotive power; Power braking and, using hydraulic brake absorb the function of locomotive wheels. The hydraulic transmission shaft several layout, each shaft supporting the use of rolling bearings.
2. Middle gear box bearing
Among the major parts of gear box is each has two gear input shaft and output shaft, among them a shaft of the gear shift gears is, the shaft and gear have clutch institution, can make one of the gear and shaft link, the transmission power; Another gear in this case just idling. Shift gears and clutch often decorate in the input shaft, for input torque is small, so help to reduce the size of the spline clutch bearings and size.
3. Axle gear box bearing
Axle gear box hydraulic transmission boxes or center gearbox output torque transfer to axle, bear will slow down and longitudinal rotating change as horizontal rotating task. Level 1 slowdown has a pair of gear box taper gear, level 2's speed gearbox and a pair of cylindrical gears. After a according to the order of magnitude gear down "after the first column cone" and "first after cone column" two kind of arrangement.
