Problems solved by technology
[0003] 1. As the cylinder piston rotates, the hydraulic oil in the cylinder generates centrifugal force due to the rotation of the cylinder piston, and the centrifugal force changes with the speed, which makes the control system more complicated and even uncontrollable; due to the rotation of the cylinder, oil distribution is required The disc has a complex structure and is prone to oil leakage; due to the requirements of the frame structure on the rotation of the cylinder piston, the structure is relatively large, the bearing fulcrum is difficult to arrange, and the moment of inertia is large
[0004] 2. All ball bearings are used. The ball bearings must bear the thrust of the oil cylinder. Due to the limited ability of the ball bearings to bear the axial force, some bearings have a short service life.
[0005] 3. The return spring is a coil spring, which is arranged on the piston. The force of the coil spring is linear, and it is arranged on the piston. It has no effect on the separation of the main and driven friction plates. The separation of the friction plates is not good, and the life of the friction plates is short
Moreover, there is no speed measuring gear at the input shaft and output shaft, so it is difficult to measure speed
Using other methods to measure speed has low precision, which makes it difficult to improve the precision of the control system
[0007] 5. The tooth form matched with the external tooth friction plate: the tooth shape matched with the external tooth friction plate is an internal gear type, because the tooth shape is too long, the processing technology is difficult, the manufacturing cost is high, and the axial error is large, which makes assembly difficult. Movement of the friction plate is stuck
