AI Technical Summary

Technical Problem

Existing wet continuously variable transmission clutches suffer from problems such as large travel, slow response, and delayed engagement due to piston pressing against friction plates and driven plates. Furthermore, the friction plates and driven plates are prone to incomplete separation due to engine oil, resulting in high dragging and coasting resistance in neutral.

Method used

The design incorporates a driven roller groove, driven raceway, and driven roller mating structure. Centrifugal force drives the driven roller to press against the friction disc and clutch disc. Combined with the design of baffles and elastic elements, the clutch function is realized, and the friction disc and clutch disc separate when the speed decreases, avoiding dragging.

Benefits of technology

It solves the problems of large stroke, slow response and delayed engagement, avoids the dragging and high sliding resistance caused by incomplete oil separation between the friction plate and the driven plate, and improves response speed and transmission efficiency.
