Abstract

The invention belongs to the technical field of transmissions, and specifically includes a continuously variable transmission mechanism and a power assembly. The continuously variable transmission mechanism includes a first planetary gear set and a second planetary gear set, the first ring gear of the first planetary gear set is connected with the second planet carrier of the second planetary gear set, and the continuously variable transmission mechanism also includes: a first The input end; the second input end; the output end, the output end is connected with the first planet carrier; the first clutch, the first clutch is arranged between the first planet carrier and the second ring gear; the second clutch, the second clutch is arranged on Between the first planet carrier and the first sun gear; the first brake, which cooperates with the second ring gear; the second brake, which is configured to control the second planet carrier and the first ring gear to be stationary or allow them to rotate freely. The continuously variable transmission mechanism has a simple structure, can efficiently balance the power input from two input ends, realize multiple continuous speed changes, and has a relatively large torque when outputting at a low rotational speed, and has a wide range of applications.

Description

technical field [0001] The invention relates to the technical field of transmissions, and specifically provides a continuously variable transmission mechanism and a power assembly. Background technique [0002] With the vigorous development of the vehicle industry, the automatic transmission function of automobiles has gradually become the mainstream design, but the structure of the traditional transmission is complicated, and the performance requirements of the driving machine are relatively high. When the vehicle is running at a low speed, it needs to provide a large torque, and when the vehicle is running at a high speed, it needs to provide a high speed. However, the cost of a high-speed, high-torque driving machine is high, which in turn leads to the high price of a high-performance automatic transmission vehicle. General-priced vehicle drives have limited performance, and generally have the defects of slow acceleration and poor climbing ability caused by insufficient t...
