Abstract

The invention discloses a parking device, a power driving system and a vehicle. The parking device is applied to the power driving system. The power driving system comprises a motor and a transmission. The motor is provided with a motor output shaft. The transmission is provided with a transmission input shaft. The transmission input shaft is connected with the motor output shaft. The parking device comprises a braking disc and a braking part. The braking disc is arranged at the connecting position between the transmission input shaft and the motor output shaft, and can synchronously rotate with the transmission input shaft and the motor output shaft. The braking part is arranged to brake the brake disc by using friction effect. According to the parking device, through the braking part, the braking disc arranged at the transmission input shaft and the motor output shaft is subjected to friction braking to achieve the aim of parking. The braking process is simpler, and unnecessary detecting devices are avoided being additionally installed so that the production cost can be reduced.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a parking device, a power drive system and a vehicle. Background technique [0002] Most of the parking devices in traditional electric vehicle transmissions are in the form of ratchets and pawls, which are arranged inside the transmission housing, occupying a large amount of space for the arrangement of transmission shaft teeth and affecting the dynamic performance of the vehicle. And because the pawl is located in the groove of the ratchet or on the boss there is uncertainty, it is necessary to arrange a position sensor for monitoring the rotation angle of the actuator motor shaft. In addition, when parking, especially when the parking gear is engaged while waiting for a red light, once the rear vehicle collides, the entire transmission may be damaged, and the maintenance cost is high, and even the transmission needs to be replaced directly. Contents of the invention [000...
