High-torque wear-free transmission clutch for vehicle

Abstract

The invention discloses a high-torque wear-free transmission clutch for a vehicle, and belongs to the technical field of clutches. The high-torque wear-free transmission clutch for the vehicle comprises a driving disc, a clutch mechanism and an actuating disc which are rotationally and coaxially arranged in sequence, wherein the clutch mechanism comprises a driven sleeve of an outer ring and a driven disc of an inner ring, the driven sleeve is radially provided with a plurality of spring collision bead mechanisms, the spring collision bead mechanisms are provided with cavity bodies, the positions, on the inner diameter surface of the driven sleeve, of the cavity bodies are provided with outlets, steel balls are arranged in the cavity bodies, and the steel balls abut against and are pressedin the outlets by springs; the outer surface of the driven disc is provided with gear teeth, and the gear teeth are in press-fit with parts, exposing from the outlets, of the steel balls; the drivingdisc is synchronously coupled with the driven sleeve in an axial movement mode; and the driven disc is synchronously coupled with the actuating disc in an axial movement mode. The transmission clutchachieves the aims that the transmission torque capacity and power performance can be improved, the problems of the frequent maintenance and short service life caused by component wear are avoided, and the operating cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of clutches, in particular to a high-torque, wear-free vehicle transmission clutch. Background technique [0002] At present, the clutches of vehicle transmissions mostly adopt a friction structure, and the clutch transmission is realized through the engagement and separation between the primary friction plate and the driven friction plate. Generally, the clutch requires frequent operations during the driving process of the vehicle to achieve effective control of the vehicle. . [0003] With the gradual increase in the number of vehicles, the smoothness of road traffic is getting worse and worse, and the operating frequency of the clutch is increased, resulting in serious wear of the friction plate and frequent maintenance, while the replacement and installation of the friction plate are very difficult, and the operating costs At the same time, the transmission torque range of the friction clutch transmissi...

Problems solved by technology

[0003] With the gradual increase in the number of vehicles, the smoothness of road traffic is getting worse and worse, and the operating frequency of the clutch is increased, resulting in serious wear of the friction plate and frequent maintenance, while the replacement and installation of the friction plate are very difficult, and the operating costs At the same time, the transmission torque range of the friction clutch transmission is generally limited by the friction material, and it cannot be used for power transmission under heavy load conditions exceeding the temperature and shear force of the friction material, thus affecting the dynamic performance of the vehicle

[0004] Therefore, there is an urgent need for a variable speed clutch that can improve the transmission torque capacity and power performance, avoid frequent maintenance and short life due to component wear, and reduce operating costs.
