Abstract

The invention provides a centralized armature independent suspension rear axle, and relates to armature rear axles. The rear axle comprises a lower swing arm, a hub assembly, a brake assembly, a support assembly, an upper swing arm, an air bag assembly, a damper assembly, a frame, a power assembly and a universal joint transmission shaft, wherein starting ends of the upper and lower swing arms arerespectively hinged with upper and lower parts of the support assembly through a pin roll assembly; tail ends of the upper and lower swing arms are respectively fastened to the frame; a parallelogramrod mechanism is formed by the support assembly, upper swing arm, lower swing arm and frame; the power assembly comprises a motor and a reducer assembly which are arranged on the frame and connectedtogether; one end of the universal joint transmission shaft is connected with the reducer assembly, and the other end of the universal joint transmission shaft is connected with the support assembly.The centralized armature independent suspension rear axle has the characteristics of high operation stability, high bearing capacity, good rotation flexibility, good comfortable feeling, light weightand the like, and can meet the performance requirement of urban delivery vehicles and microcirculation buses.

Description

technical field [0001] The invention relates to an electric drive rear axle, in particular to a centralized electric drive independent suspension rear axle. Background technique [0002] At present, the mainstream drive system used by electric vehicles is based on traditional vehicles, replacing the engine and gearbox with a central motor or deforming the traditional rigid bridge—integrating the central motor, reducer, and rigid bridge carrier. The rigid electric drive axle takes up a lot of space, and its comfort and handling stability are relatively low. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a centralized electric drive independent suspension rear axle to improve the comfort and handling stability of the whole vehicle and simplify the overall structure. [0004] The technical solution to solve the above technical problems is: a centralized electric drive independent suspension rear axle, including wh...
