Abstract

The invention discloses an axle assembly driven by new energy. The axle assembly driven by the new energy is an integrated electric drive axle assembly, and comprises a brushless direct current motor controller, a brushless direct current motor, a two-stage reduction gear assembly, an integrated type axle housing, a half axle and a brake drum. Due to the fact that fixed ratio transmission is adopted by the two-stage reduction gear assembly, transmission efficiency is high, the structure is simple and compact, and the axle assembly driven by the new energy is convenient to manufacture and meets the power output requirements of electric vehicles when the electric vehicles are driven on the flat ground and a slope. Due to the fact that the brushless direct current motor and the integrated type axle housing are arranged in parallel, the gravity centers of the whole vehicles are lowered effectively. Meanwhile, due to the fact that a multistage parallel drive mode is adopted by the brushless direct current motor controller to replace an expensive intelligent power module, the cost is reduced effectively. The integrated design scheme can be applied to the electric vehicles, especially electric sightseeing vehicles and electric cleaning vehicles, more effectively.

Description

technical field [0001] The invention relates to a drive axle assembly of a new energy vehicle and its control, in particular to a drive assembly of a new energy drive axle. Background technique [0002] Electric vehicles have the characteristics of energy saving, environmental protection and light body structure, and with the continuous breakthrough of battery technology, electric vehicles have attracted more and more attention from the government and individuals. [0003] In the existing electric vehicle drive structure, the drive axle structure using the hub motor uses the electronic differential to cancel the mechanical differential structure to make the body lighter, but the electronic differential technology does not yet have the technical maturity for large-scale application , has not yet been widely used, and the technology is complicated. [0004] Patent No. ZL03235728.1 invented a transmission device for drive axles of electric vehicles, which can realize variable ...
