Embodiment Construction

[0023] 1. Transmission process of transmission power input and output sequentially:

[0024] exist image 3 , Image 6 Middle: Power input shaft conical roller (1) → friction power transmission roller (2) → power output shaft conical roller (3)

[0025] In the process of power transmission, the power rotates through the input shaft conical roller (1), which drives the friction power transmission roller (2) on the surface of the input shaft and output shaft conical roller to rotate through the roller compression hydraulic cylinder, and then friction The power transmission roller (2) is pressed and connected with the surface of the output shaft conical roller (3) at the same time, thereby driving the output shaft conical roller (3) to rotate and output power torque.

Abstract

The invention relates to a roller-drive continuously variable transmission box. A power transmission mechanism refers to the drawing attached to the specification. Through the rotation of an input shaft conical roller, power drives two friction power transmission rolling wheels arranged in the middles of the surfaces of the input shaft conical roller and an output conical roller and capable of producing friction forces through using a micro pressing hydraulic cylinder for pressing the surfaces of the conical rollers to transmit, so that the output conical roller is driven to rotate so as to output a power torque. A speed change mechanism refers to the drawing attached to the specification. In order to realize the adjustment of the rotating speed, the rotating speed is utilized for adjusting a motor shaft end gear of a servo motor to drive the matched rotating speed to adjust a screw rod gear to rotate, then a screw rod drives a power transmission rolling wheel support plate matched with the screw rod to linearly move back and forth in the axial direction of the screw rod, the power transmission rolling wheel support plate then drives the friction power transmission rolling wheels to horizontally move back and forth on different pressing and meshing diameter positions on the surfaces of the input shaft conical roller and the output conical roller, and different output rotating speeds are obtained, so that the rotating speed required to be set by the output conical roller is reached.

Description

technical field [0001] The technical proposal relates to a speed change device in the process of power transmission, and is especially suitable for the speed change part after the output power of an engine of an automobile, a motorcycle and a power motor. Background technique [0002] At present, all automatic transmissions on automobiles, motorcycle engines or power motors can be divided into two categories: automatic gear transmission and automatic continuously variable transmission according to the transmission type. The automatic gear transmission has the characteristics of large output torque, but it has disadvantages such as complex structure, high maintenance cost, high fuel consumption, gear shock during driving, and poor comfort. However, the current automatic continuously variable continuously variable transmission (CVT) is mainly based on the steel belt (or steel chain) friction cone wheel type continuously variable transmission, which passes through a steel belt ...
