Abstract

The invention discloses a pure electric vehicle power assembly. The pure electric vehicle power assembly comprises a transmission lower shell and a transmission upper shell; change wheel sets on the two sides are rotatably connected through a caterpillar band; and a transmission assembly is arranged in the transmission lower shell. According to the pure electric vehicle power assembly provided bythe invention, through meshing connection between a gear and a rack and clearance fit between a through groove and a sliding rod, the change wheel sets on the two sides can move close to or away fromeach other at the same time, then the contact position between the change wheel sets and the caterpillar band is changed, stepless speed change is better achieved, and the use experience of a user isimproved; a single driving device can achieve alternate change of the change wheel sets, the speed change synchronization is greatly improved, more energy is saved, the lower transmission shell and the upper transmission shell can be rapidly disassembled and assembled under the action of an extension spring through clamping connection of a limiting clamping plate and a limiting clamping groove andclearance fit of a circular supporting rod and a circular groove, and therefore, the interior of a transmission is convenient to maintain or repair.

Description

technical field [0001] The invention relates to the technical field of pure electric vehicle power assembly, in particular to a pure electric vehicle power assembly. Background technique [0002] The powertrain is abbreviated as PT, which refers to a series of components and components that generate power on the vehicle and transmit power to the road surface. In a broad sense, it includes engines, gearboxes, drive shafts, differentials, clutches, etc., but usually Next, the powertrain generally only refers to the engine, transmission, and other parts integrated into the transmission, such as clutch / front differential, etc. [0003] When the pure electric vehicle powertrain in the prior art is in use, it cannot better realize the stepless speed change, which reduces the user experience, and it is impossible to realize the alternating change of the speed change wheel sets through a single driving device, thereby reducing the speed change synchronization, and more energy-consum...
