Problems solved by technology

This speed regulation method is simple in structure, but the axial dimension is not compact enough, and the bearing connecting the hollow screw and nut and the moving cone will bear relatively large pressure and friction, which may cause excessive heat generation in the bearing and affect the life of the bearing

Abstract

The invention relates to the technical field of vehicle speed transmissions, in particular to a speed adjustment mechanism for a conical plate type continuously variable transmission and the conical plate type continuously variable transmission. The speed adjustment mechanism for the transmission comprises a drive shaft coupled to a driver, a drive nut sleeving the drive shaft, and a first shifting fork and a second shifting fork at two ends of the drive nut, wherein the first shifting fork has a first work part pressed against a first movable conical plate on a driving shaft; the second shifting fork has a second work part pressed against a second movable conical plate on a driven shaft; and the first and second shifting forks also respectively have first and second support parts, which respectively sleeve the drive shaft so as to improve the stiffness of the first and second shifting forks. The axial dimensions of the speed adjustment mechanism are greatly simplified, so that the structure of the conical plate continuously variable transmission equipped with the speed adjustment mechanism is more compact, and in addition, the costs for manufacturing, machining, mounting, maintenance and so on are lowered.

Description

Technical field [0001] The invention relates to the technical field of vehicle speed change devices, in particular to a conical disc type continuously variable transmission speed regulating mechanism and the conical disc type continuously variable transmission. Background technique [0002] Hybrid vehicles are equipped with two power sources, engine and electric motor, to a certain extent, reducing costs and pollution emissions, but the space requirements for the front compartment of the vehicle have been greatly increased. A series of measures are required without changing the size of traditional vehicles. Optimize the layout of the front cabin, for example, change the 4-cylinder engine to a 3-cylinder engine on the basis of ensuring power, and minimize the size of the front cabin components. Among them, as an important part of the automobile transmission system, the transmission occupies an important position in the front cabin, and its structural size also directly affects the...
