Problems solved by technology

Currently, the continuously variable transmissions used in automobiles are only known to be used in a small amount of steel belt type continuously variable transmissions. Its superior performance is incomparable to the stepped transmissions, but there are also some problems, such as easy slipping, Large wear, short life, difficult to apply to large-displacement vehicles, etc.

Abstract

The invention relates to a gear stepless speed changer, which comprises: planet gear system and one-way bearing as one-way clutch, wherein the gear system comprises an active sun wheel connected to the power input; there are 3-6 output planet wheels meshed with the circumference of active sun wheel; the output planet wheel is mounted on the planet wheel support fixed with the power output; each output planet wheel is meshed with one tooth ring; one-way bearing is arranged on the tooth ring; the output planet wheel and the planet wheel support are the output; the revolution speed of planet wheel support is the output rotation speed; the active sun wheel is the input; the tooth ring is the input used when changing speed; the power of driving tooth ring can be obtained from the input axle; the rotation direction of tooth ring is same as active sun wheel; the one-way bearing sheathes the tooth ring or the element connected to the tooth ring, to rotate the tooth ring at single direction. The invention has simple structure, stepless speed change, and wider speed range.

Description

technical field [0001] The invention relates to a speed change device, in particular to a gear step-type continuously variable speed change device with simple structure and large speed change range. Background technique [0002] With the further deepening of the industrialization process, transmissions are widely used in various occasions and fields, and the most common ones are used in various vehicles and other mechanical equipment. There are two types of transmissions, step and stepless. In today's automotive field, most of the transmissions are stepped. Because the efficiency of the stepped transmission is not as high as that of the continuously variable transmission, people have been researching and developing a reliable and durable continuously variable transmission to replace the existing stepped transmission in the automobile manufacturing industry. Currently, the continuously variable transmissions used in automobiles are only known to be used in a small amount of ...
