Abstract

The invention discloses a spiral guiding stepless variable transmission which comprises a driving wheel assembly, a transmission belt and a driven wheel assembly, wherein a radial pin is fixedly arranged at the end part of a moving disc; a roller is arranged on the radial pin; a guiding block is arranged on the fixing disc; a spiral guiding inclined surface is arranged on the guiding block; the driving wheel assembly further comprises a synchronous ring and a disc spring; the synchronous ring leans against the outer ring of a rolling bearing; the disc spring leans against the synchronous ring and a spring base. According to the spiral guiding stepless variable transmission disclosed by the invention, the roller and the spiral guiding inclined surface in match with the roller are adopted to guide the movement track of a moving wheel in the speed change process, the friction between the moving wheel and the transmission belt is small, and the transmission belt has less abrasion and is long in service life; moreover, when an automobile is accelerated to start and speed up from an idle speed state, as the driven wheel assembly has certain rotation speed in the idle speed state, the rotation speed of the driven wheel assembly of the automobile changes stably in the starting and speeding process, and the automobile is good in starting stability.

Description

technical field [0001] The invention relates to a transmission mechanism, in particular to a continuously variable clutch. Background technique [0002] Usually, the continuously variable clutch includes a driving wheel combination, a driven wheel combination and a transmission belt. The driving wheel combination is connected with the engine crankshaft. When the engine crankshaft rotates, the driving wheel drives the driven wheel to rotate through the transmission belt to output power. [0003] The driven wheel combination includes a moving plate and a fixed plate, and the transmission belt is located between the moving plate and the fixed plate. During the speed change process, the transmission belt pushes the moving plate to move axially along the driven shaft to change the diameter of the transmission belt on the moving plate and the fixed plate. to the position to realize the speed change. [0004] In the continuously variable clutch in the prior art, the moving plate o...
