High-reliability clutch mechanism

Abstract

The invention relates to a high-reliability clutch mechanism which comprises an inner shaft sleeve 1, an outer sleeve ring 2 and a driving component, wherein the outer edge of the inner shaft sleeve 1 is at least provided with a wedge-shaped groove; the driving component is arranged in the wedge-shaped groove, and the driving part, the outer sleeve ring 2 and the wedge-shaped groove form a one-way close fit structure capable of realizing forward-rotation clamping. The high-reliability clutch mechanism can be used for solving the problems of high fault occurrence possibility, poor reliability and high abrasion possibility of an existing clutch mechanism, has the advantages of high operation reliability, high stability, low noise, simple structure, easiness for manufacturing, high durability and the like, and is mainly used for manufacturing clutch devices of various vehicles and power devices.

Description

technical field [0001] The invention relates to a clutch control device used in a mechanical transmission system, in particular to a high-reliability clutch mechanism. Background technique [0002] At present, the clutch control device used for power transmission on bicycles, electric bicycles, and electric tricycles is a ratchet mechanism, which is mainly composed of a ratchet wheel with a tooth groove and a pawl linked with the drive shaft, which drives the pawl to rotate through the drive shaft , the ratchets are pushed into the tooth grooves on the ratchet in turn along with the rotation, pushing the ratchet to rotate, thereby driving the wheel to rotate. Because the pawl and each tooth groove on the ratchet wheel are always single-point line contact push-up cooperation, and the pawl slides to the next adjacent tooth groove after pushing a tooth groove on the ratchet wheel, the ratchet is always in the same position. Stop sliding and push the top, because the pawl is pu...

AI Technical Summary

Problems solved by technology

Because the pawl and each tooth groove on the ratchet wheel are always single-point line contact push-up cooperation, and the pawl slides to the next adjacent tooth groove after pushing a tooth groove on the ratchet wheel, the ratchet is always in the same position. Stop sliding and push the top, because the pawl is pulled by the tension spring, the uninterrupted sliding of different amplitudes is easy to deform the tension spring and lose its proper elasticity, resulting in the pawl not being pulled back in time. As a result, it cannot be pushed into the tooth grooves on the ratchet in turn as expected, resulting in slippage of the pusher, work failure, and failure to transmit the driving force of the driving wheel. Therefore, its disadvantages are that it is prone to failure, poor reliability and stability of work

The clutches of motor vehicles mostly use the clutch structure that relies on the friction force of the clutch plate, that is, the friction plate to push the driven wheel, so as to transmit the driving force of the driving wheel. Due to the large friction surface of the friction plate, repeated use will make it wear out quickly , and there will also be local slippage, which will affect the reliability of its work. Therefore, its disadvantage is that the driving force transmission part, that is, the friction plate, is easy to wear, and the work reliability will also be affected to a certain extent.
