Problems solved by technology

[0004] But above-mentioned pendulum-type continuously variable transmission has the following problems: 1, when the bevel gear rotates forward or reversely, the two planetary bevel gears can only rotate in one direction towards a fixed direction, so that there is only one direction of rotation of the output shaft, It is impossible to switch between forward gear and reverse gear, and the scope of application is small; 2. The swing lever swings back and forth. When it swings to the point where the swing direction needs to be changed, the speed of the swing lever is 0, and the speed of the bevel gear is 0 at this time, which is the same as The matching planetary bevel gear rotates at 0, which causes the output shaft to stop rotating and the vehicle speed to be uneven

Abstract

The invention provides a dual-oscillating-rod friction ratchet wheel speed change device and belongs to the technical field of speed changers. By means of the dual-oscillating-rod friction ratchet wheel speed change device, the problems that an existing oscillating rod type stepless speed change device is instable in speed and incapable of achieving reverse power output are solved. The dual-oscillating-rod friction ratchet wheel speed change device comprises an input shaft and an output shaft arranged parallel to the input shaft; a first oscillating rod and a second oscillating rod are connected to the input shaft through a transmission structure; a supporting shaft is arranged between the input shaft and the output shaft and is parallel to the input shaft, and the center axis of the supporting shaft, the center axis of the input shaft and the center axis of the output shaft are located in the same plane; the first oscillating rod and the second oscillating rod are hinged to the two ends of the supporting shaft correspondingly, and under the action of the transmission structure, the first oscillating rod and the second oscillating rod oscillate in the opposite movement directions with the supporting shaft as a center; and a first one-way transmission assembly is arranged between the first oscillating rod and the output shaft, and a second one-way transmission assembly is arranged between the second oscillating rod and the output shaft. The dual-oscillating-rod friction ratchet wheel speed change device has the advantages of achieving stepless speed change, being convenientto adjust and stable in output speed, achieving positive and negative power output and the like.

Description

technical field [0001] The invention belongs to the technical field of transmissions, and relates to a transmission device, in particular to a friction ratchet transmission device with double swing bars. Background technique [0002] During the driving process of the vehicle, in order to meet the requirements of the vehicle for traction and driving speed under different driving conditions, a transmission needs to be installed in the vehicle. The main function of the transmission is to adjust the torque and speed that the engine finally outputs to the wheels by changing the speed, so as to meet the requirements of the vehicle for traction torque and speed in different usage states. Among the existing vehicle transmissions, the gear meshing mechanical transmission is the most commonly used. This transmission is made of multiple gears with different numbers of teeth meshing with each other and driven by racks or belts. Its disadvantages are: When a car needs to obtain differen...
