Abstract

The invention discloses a conical friction wheel type automobile continuously variable transmission and belongs to the technical field of automobile transmissions. Power of an engine is transferred through mutual matching of a driving conical friction wheel, a driven conical friction wheel, a forward gear friction wheel, a first reverse gear friction wheel and a second reverse gear friction wheel, the transmission ratio can be continuously changed, and therefore the optimal matching of a transmission system and working conditions of the engine is obtained. Meanwhile, the control mechanism is simple in structure, easy to operate and high in transmission efficiency.

Description

technical field [0001] The invention belongs to the technical field of automobile transmissions, in particular to a conical friction wheel type automobile continuously variable transmission. Background technique [0002] Automobile transmission is one of the key components in automobiles. Automatic transmission is the development direction of automobile transmission. At present, automobile automatic transmission mainly includes planetary gear automatic transmission and belt type continuously variable transmission. Since the adoption of the hand-operated three-speed planetary gear transmission and Ford's adoption of the second-speed planetary gear transmission, it has developed rapidly. It has eliminated the differences in the driver's shifting technology, provided good transmission ratio conversion performance, and improved the vehicle. It can reduce driver fatigue, improve driving safety, reduce engine exhaust pollution and make the engine work in the most economical zone, ...
