Abstract

The invention provides a new energy automobile wheel edge split-type driving assembly. The new energy automobile wheel edge split-type driving assembly comprises a frame and wheels, and further comprises suspension gearboxes and motors which are arranged on the inner sides of wheel hubs on the two sides and in left-right symmetry, motor shafts of the motors are connected with driving shafts and drive the driving shafts through gear sets in the suspension gearboxes, and the driving shafts are connected with the wheel hubs and drive the wheel hubs. According to the new energy automobile wheel edge split-type driving assembly, the matching compatibility with traditional frames is very good, design is simple, adjustment is easy, classical design technologies can be adopted, a secondary development structure is not required, the transmission efficiency of new energy automobiles is improved, the power loss is decreased, the recovery rate of braking energy is increased, electricity is saved,the driving continuation mileage is increased or battery consumption is decreased, the comprehensive cost is lowered, the reliability is high, the service life is long, the preserving and maintainingcosts are lowered, and thus a driving system is simplified.

Description

technical field [0001] The invention relates to the technical field of new energy vehicles, in particular to a wheel-side-separated drive assembly of a new energy vehicle. Background technique [0002] In February 2017, the National Development and Reform Commission, together with the Ministry of Science and Technology, the Ministry of Industry and Information Technology, and the Ministry of Finance, organized the compilation and release of the "Guiding Catalog of Key Products and Services for Strategic Emerging Industries (2016 Edition)" (abbreviation: "Catalogue"). Among them, among the products that involve the key cultivation of new energy vehicles, wheel motors are impressively listed. Pure electric bus power system solutions are mainly divided into two categories: centralized drive and distributed drive. "Distributed drives are mainly divided into wheel-side motors and hub motors." Due to high drive efficiency and advanced technology, distributed drive technology has ...
