Four-speed transmission integrated system

Abstract

The invention discloses a four-gear transmission integrated system. The four-gear transmission integrated system comprises a motor, a hydraulically controlled gear shifting group, a transmission input group, a first planetary gear group, a second planetary gear group, a first transmission shaft and a second transmission shaft, wherein the motor and the hydraulically controlled gear shifting group are coaxially connected to the first transmission shaft, the transmission input group, the first planetary gear group and the second planetary gear group are coaxially connected to the second transmission shaft, the first planetary gear group and the second planetary gear group are coaxially connected, the transmission input group is in engagement connection with the hydraulically controlled gear shifting group, and a first brake is arranged at the outer side of the first planetary gear group. The four-gear transmission integrated system has high flexibility, can realize high-speed running and climbing and adapts to various complicated working conditions.

Description

technical field [0001] The invention relates to the technical field of new energy vehicles, in particular to an integrated system of a four-speed transmission. Background technique [0002] With the development of science and technology, the problems of energy constraints and environmental pollution are becoming more and more serious. Vigorously developing new energy can effectively solve energy and environmental problems and achieve sustainable development. With the improvement of living standards, more and more people own cars. With the increase of the number of cars, it is easy to cause problems such as road congestion and traffic accidents. More importantly, a large number of cars quickly consume energy such as oil. At the same time, the pollution of the environment has been greatly aggravated. Therefore, in the development of new energy, the development of new energy vehicles is particularly important. [0003] With the maturity of new energy technology, the drive syst...

AI Technical Summary

Problems solved by technology

At present, the power drive system of pure electric vehicles mostly adopts a transmission system composed of a wet clutch and a double planetary row, but there are still some shortcomings, such as in pure electric mode, it cannot achieve high-speed driving and cannot meet the needs of use. Yes, in some pure electric vehicles, the car has insufficient power during the climbing process and cannot achieve high-speed driving

[0004] In addition, in some driving systems, the system energy utilization rate is low, which increases some living costs
