Continuously variable transmission with adjustable transmission ratio characteristic curve

Abstract

The invention discloses a continuously variable transmission with an adjustable transmission ratio characteristic curve. The continuously variable transmission comprises a shaft sleeve, a spring seat, a moving wheel, a sliding cover and a spring, and further comprises a swing arm, a cylindrical roller, an inclined plane guide block and an eccentric bolt assembly; one end of the swing arm is hinged to the spring seat, and the other end of the swing arm is connected with the cylindrical roller; the inclined plane guide block is hinged to the moving wheel; the eccentric bolt assembly comprises an eccentric bolt and a nut; and one side of the inclined plane guide block abuts against an eccentric cylindrical section, and the other side of the inclined plane guide block is provided with a guide inclined plane abutting against the cylindrical roller. According to the continuously variable transmission with the adjustable transmission ratio characteristic curve, the transmission ratio characteristic curve of the transmission can be changed by adjusting the installation position of the eccentric bolt, and therefore the continuously variable transmission can better meet the driving requirements of vehicles in different areas.

Description

technical field [0001] The invention relates to the technical field of a transmission, in particular to a continuously variable transmission. Background technique [0002] Motorcycle is a kind of mobile and flexible means of transportation, which is widely used in mountains and plains. However, motorcycles have different requirements on the speed change performance of their continuously variable transmissions when they are running on mountains and plains. For example, when a motorcycle is often driven in a mountainous area, it will often start the vehicle on an uphill section. At this time, the low-speed output torque of the continuously variable transmission of the vehicle is required to be large, which can ensure the climbing needs of the vehicle, so it is often used in mountainous areas. The transmission ratio characteristic curve of the continuously variable transmission of motorcycles is gentler, and the acceleration process from low speed to high speed takes longer; w...

Problems solved by technology

[0003] In view of this, the object of the present invention is to provide a continuously variable transmission with an adjustable transmission ratio characteristic curve to solve the problem that the transmission ratio characteristic curve of the existing continuously variable transmission cannot be adjusted, so that the continuously variable transmission cannot conveniently meet the needs of vehicles in mountainous and peaceful areas. The technical problem of the different requirements for the transmission performance when driving under two different road conditions
