A new energy vehicle reducer gear assembly

Abstract

The invention discloses a reducer gear assembly for a new energy vehicle, which comprises a base, a circular shell is provided on the top of the base, a first conical shell is provided at one end of the circular shell, and a second conical shell is provided at the other end of the circular shell. The cone-shaped shell, the inside of the circular shell is equipped with a transmission mechanism for normal driving and deceleration transmission of the vehicle, the inner side of the transmission mechanism is equipped with an intermediate shaft mechanism for fault switching power, and the inner side of the first conical shell is equipped with an input shaft mechanism for power input , the inner side of the second cone-shaped housing is provided with an output shaft mechanism for power output. The present invention is provided with a second planetary gear assembly in the transmission mechanism to provide spare parts for running when the reducer fails. The pusher is set to switch the power transmission parts when the reducer fails. Through the cooperation between these mechanisms, the problem of the increase in transportation and maintenance costs caused by the failure of the existing reducer gear assembly to work is solved. .

Description

technical field [0001] The invention relates to the technical field of new energy vehicles, in particular to a new energy vehicle reducer gear assembly. Background technique [0002] New energy vehicles refer to the use of unconventional vehicle fuels as power sources (or the use of conventional vehicle fuels and new vehicle power devices), and the comprehensive vehicle power control and advanced technology in driving, the formation of advanced technical principles, with Automobiles with new technology and new structure. In new energy vehicles, a motor is used for driving, and the output end of the motor is often connected to a planetary gear reducer. Planetary gear reducer is also called planetary reducer, servo reducer. In the reducer family, planetary reducers are widely used in servo motors, stepping motors, DC motors and other transmission systems due to their small size, high transmission efficiency, wide deceleration range, and high precision. Its function is to re...

AI Technical Summary

Problems solved by technology

[0003] The gear structure of the existing planetary reducer is complicated, and multiple gears cooperate with the transmission. When one of the gears or positions is damaged, the reducer cannot work normally, which will affect the normal driving of the vehicle. , the vehicle cannot continue to drive, so the vehicle needs to be transported to a professional repair shop for maintenance, which will increase the transportation cost in the maintenance cost of the reducer
