Multi-gear-position transmission

Abstract

The invention provides a multi-gear-position transmission. The multi-gear-position transmission comprises a left gear and a right gear. Circular ring grooves are formed in a left gear body and circular ring grooves are formed in a right gear body. The left gear body and the right gear body together define circular ring cavities in an enclosing mode. Disc-shaped connecting bodies are put in the circular ring cavities. Teeth arranged at intervals are formed at the outer edges of the disc-shaped connecting bodies. Multiple teeth rings are formed in the surfaces of the circular ring grooves of the left gear body. Multiple teeth rings are formed in the surfaces of the circular ring grooves of the right gear body. The disc-shaped connecting bodies are engaged with part of teeth in one teeth ring on the left gear body and part of teeth in one teeth ring on the right gear body. Rotary shafts are disposed in the centers of the disc-shaped connecting bodies. The whole circular cross sections, passing through the center points of the disc-shaped connecting bodies, of the circular ring cavities are first planes, and the rotary shafts are located on the first planes. The left gear rotates to drive the disc-shaped connecting bodies to rotate around the rotary shafts, and the disc-shaped connecting bodies drive the right gear to rotate. The multi-gear-position transmission has the advantage that multiple gear positions are easy to arrange.

Description

technical field [0001] The invention relates to a transmission, in particular to a multi-speed transmission with multiple gear positions. Background technique [0002] There are two types of transmissions today: stepped transmissions and continuously variable transmissions. Stepped transmissions have been around since the invention of automobiles. They use gears for transmission. The disadvantage is that when the transmission has fewer gears, the smoothness of shifting is not good. When there are many gears, the transmission will be very heavy and very large. Continuously variable transmission uses a steel belt for transmission. The biggest disadvantage is that it cannot output high power and the transmission efficiency is low. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a multi-speed transmission, which has the characteristics of easy setting of multi-gears. [0004] In order to solve the problems of t...
