Abstract

The invention discloses a hub motor driving device, which comprises a transmission hub, a speed reducer and a driving motor, wherein the transmission hub is arranged on a hub, a speed reducer casing of the speed reducer is arranged on a suspension of a vehicle, a motor front end cap of the driving motor is fixedly arranged on the speed reducer casing to seal the speed reducer, a motor shaft of the driving motor is connected with an input shaft of the speed reducer, and an output shaft of the speed reducer is connected with the transmission hub. The device has the advantages that a large amount of transmission parts of the traditional vehicle is saved, the structure of the vehicle is simpler, a plurality of complicated driving methods can be realized, the device is suitable for a plurality of new energy vehicle techniques, and the energy consumption and the mechanical abrasion are reduced.

Description

technical field [0001] The invention relates to the technical field of automobile electric drive, in particular to a wheel hub motor drive device. Background technique [0002] For traditional vehicles, clutches, transmissions, transmission shafts, differentials and even transfer cases are all essential, and these components are not only heavy, but also make the structure of the vehicle more complicated, and there are also problems that require regular maintenance, The problem of high failure rate; for this reason, a new type of vehicle power scheme is currently needed to replace the powertrain of traditional vehicles. [0003] In-wheel motor transmission technology is also called in-wheel motor transmission technology. Its biggest feature is to integrate the power device, transmission mechanism and braking device into the wheel hub, which greatly simplifies the mechanical parts of electric vehicles and reduces power consumption and energy loss. .
