Problems solved by technology

However, since the vector direction of the control trajectory is the same as that of the speed regulation stroke, and the scalar quantity is small, the adjustment of the speed regulation stroke is relatively fast, and the smoothness of shifting and shifting is poor.

Abstract

The invention discloses a speed change device, which relates to the field of transmission devices and aims to solve the problem of poor smoothness of shifting and shifting of a traditional infinitely variable speed star wheel transmission device. The main points of the technical solution include a plurality of transmission balls, an input ring and an output ring linked with the transmission ball, a positioning shaft around which the transmission ball rotates, and an adjustment ring for controlling the swing of the positioning shaft. The two ends of the positioning shaft are respectively connected with a first fixed ring and a second fixed ring in which the transmission ball cover is placed, and the first fixed ring and the second fixed ring are respectively provided with a sliding hole and a sliding hole for the positioning shaft to swing. Sliding slot. The adjusting ring is embedded in the inner circumference of the first fixed ring, and the outer wall is provided with a curved adjusting groove. One end of the positioning shaft is embedded in the sliding groove, and the other end is embedded in the adjusting groove through the sliding hole, and rotating the adjusting ring can control the swinging of the positioning shaft. The present invention achieves the effect of improving the smoothness of shifting.

Description

technical field [0001] The present invention relates to the field of transmission devices, and more particularly, to a speed change device. Background technique [0002] The speed change device is suitable for various fields such as mechanical equipment, bicycles, electric vehicles, automobiles, etc. The bicycle speed change transmission device changes the speed of the vehicle by changing the cooperation of the chain and the gear discs of different front and rear sizes. [0003] A continuously variable planetary gear does away with the traditional way of shifting a chain from one gear to another, with two rotating discs and a set of balls between them. [0004] figure 1 It is a schematic diagram of the shifting principle of the infinitely variable star wheel transmission device, including a strut 101, a strut 102 is symmetrically arranged on the strut 101, a rotating shaft 103 is connected between the two struts 102, and a rolling ball 104 is sleeved on the rotating shaft 1...
