Abstract

The invention relates to an interlocking type gear shifting device of an electric automobile. The interlocking type gear shifting device comprises a first gear shifting mechanism and a second gear shifting mechanism. The first gear shifting mechanism and the second gear shifting mechanism are both arranged in a transmission box, an interlocking mechanism is arranged between a first worm gear and a second worm gear, the first worm gear is interlocked with the second worm gear through the interlocking mechanism, and a sensor detects the rotation states of the first worm gear and the second worm gear. By means of the interlocking type gear shifting device of the electric automobile, gear shifting time is short, a gear selecting device is not required to be arranged additionally, and the structure is compact. The cost of a transmission is greatly reduced, and large-batch production is facilitated. Interlocking of the two worm gears is achieved through an interlocking steel ball, the interlocking structure prevents gear disorder caused by the fact that a motor is subjected to external disturbing or receives wrong control signals and a gear shifting motor works simultaneously, and the device is reliable in performance and suitable for the multi-gear electric automobile. The device has excellent expansibility and can be designed into a multi-gear shifting device according to actual design requirements of automobiles.

Description

technical field [0001] The invention relates to the technical field of vehicle transmission systems, in particular to the technical field of electric vehicle transmission systems, and specifically refers to an interlocking shift device for electric vehicles. Background technique [0002] Because the motor itself has speed regulation performance, in the powertrain of the initial pure electric vehicle, the driving motor is usually equipped with a single-speed ratio reducer to realize stepless speed regulation. However, with the development of electric vehicles, the requirements for electric vehicles are getting higher and higher. The lack of power, economy, and driving range of the drive motor with a single-speed ratio reducer is becoming more and more obvious. Therefore, The requirement for electric vehicles to develop in the direction of multiple gears is becoming more and more urgent. However, after the number of gears in the transmission increases, especially after the nu...
