Problems solved by technology

The most widely used at present is the form of centralized motor drive, which requires the motor to transmit torque to the wheels through mechanical devices such as reducers, differentials, drive shafts, and universal joints. This way of transmitting torque layer by layer makes the drive form The structure is complex, the transmission efficiency is low, and at the same time, i

Abstract

The invention relates to a universal deceleration system, in particular to a novel universal deceleration system of a tri-fork rod planetary gear train of an electric automobile. The novel universal deceleration system of the tri-fork rod planetary gear train of the electric automobile comprises a motor, a planetary gear train deceleration mechanism, a tri-fork rod type universal transmission mechanism and wheels, the motor is connected with the planetary gear train deceleration mechanism, the planetary gear train deceleration mechanism is connected with the tri-fork rod type universal transmission mechanism, and the tri-fork rod type universal transmission mechanism is connected with the wheels. According to the novel universal deceleration system of the tri-fork rod planetary gear train of the electric automobile, a differential mechanism is removed, transmission efficiency is improved under the premise of not increasing unsprung mass, a driving system is made to be more simple and compact, automobile body weight is lightened, and energy consumption is reduced.

Description

technical field [0001] The invention relates to a universal deceleration system, in particular to a novel tripod planetary gear train universal deceleration system for an electric vehicle used in an electrically driven motor vehicle. Background technique [0002] With the continuous depletion of oil resources and the continuous improvement of people's awareness of environmental protection, the development of the traditional fuel automobile industry is facing more and more severe challenges. Therefore, the research and development of electric vehicles that can use clean energy and achieve "zero emissions" has become the goal of many large automobile manufacturing companies in the world today. There are two driving forms of electric vehicles: one is the centralized motor drive form, and the other is the electric wheel drive form. The most widely used at present is the form of centralized motor drive, which requires the motor to transmit torque to the wheels through mechanic...
