Problems solved by technology

The torque transmission realizes automatic stepless (or multi-stage) speed change, effectively overcomes the stepped (4-6 stage) speed change mode of ordinary mechanical transmissions, the complex structure of electronically controlled hydraulic automatic transmissions, and the low transmission of metal belt continuously variable transmissions The disadvantage of torque is that it has the same adaptive transmission performance as the hydraulic torque converter, the same continuously variable transmission capability as the metal belt type continuously variable transmission, and the same high efficiency as the ordinary mechanical transmission, as well as the simple structure and low cost that other types of transmissions do not have. Low cost, can be applied to various occasions that require a transmission

Embodiment Construction

[0010] In this embodiment, 12 torque reducing teeth 4 are provided on the driving wheel 1 and the driven wheel 2, and the moment reducing teeth 4 slide in the torque reducing tooth grooves 8 on the driving wheel 1 and the driven wheel 2, and the force is stored. Mechanism tension spring 6 and compression spring 7 are radially positioned according to the magnitude of the applied force, and the coil spring 5 controls all the torque reducing teeth 4 to reduce diameter synchronously. The torque variable diameter teeth 4 on the driving wheel 1 and the driven wheel 2 are transmitted by the toothed belt 3. The tooth pitch on the toothed belt 3 is the same as the tooth pitch at the minimum tooth diameter of the torque variable diameter teeth 4. In order to facilitate the realization of stepless Or multi-stage torque transmission, the number of teeth on the toothed belt 3 is far more than the number of teeth on the torque variable diameter tooth 4, when the torque variable diameter toot...

Abstract

A torque speed transmission has 8-16 torque reducer gear on the active wheel and passive wheel which are changing uniformly from larger to smaller. The torque reducer gear slides in the torque reducer groove. The torque reducer gear is pulled and pressed by pulling spring and pressing spring so that the torque reducer gear is positioned in the torque reducer groove based on the force. The multilevel or non-level moment speed changing is achieved due to the synchronous position changing of the torque reducer gear controlled by wind spring.

Description

technical field [0001] The invention belongs to a mechanical transmission device, in particular to a torque transmission used in various mechanical transmission systems such as various motor vehicles, heavy-duty winches, and electric bicycles that require high torque and low speed starting. Background technique [0002] At present, mechanical transmission variable speed technology is a traditional technology both at home and abroad. The theoretical basis of mechanical transmission speed change is to amplify the torque by reducing the speed. There are many ways to achieve this purpose, such as the use of multi-stage gears or transmission wheels with large speed ratios. The torque transmission realizes automatic stepless (or multi-stage) speed change, effectively overcomes the stepped (4-6 stage) speed change mode of ordinary mechanical transmissions, the complex structure of electronically controlled hydraulic automatic transmissions, and the low transmission of metal belt co...
