The invention provides a rear axle assembly with multiple transversely-arranged leaf springs and balancing poles. The rear axle assembly comprises a rear axle support assembly (1), a balancing pole assembly (2), a first rear steel plate spring lower piece assembly (3), a second rear steel plate spring lower piece assembly (4), a left rear horn (5), a right rear horn (6), a left damper (7) and a right damper (8). The rear axle assembly has the advantages that the transversely-arranged steel plate springs integrate spiral springs and swing arms of an original independent suspension, and the rear axle assembly has riding comfort of the independent suspension, also has the advantages that the structure is simple, occupied space is small, the number of parts is small, cost is low and reliability is high, and is beneficial to later manufacturing; through the leaf springs and the dampers, the performance of a disconnected rear axle is achieved, and good running stability and riding comfort are achieved while it is guaranteed that the structure is simple; by means of the balancing pole assembly of a special structure, an automobile has a good anti-tipping effect, and running security is improved.
Description
technical field [0001] The invention belongs to the technical field of automobile design and manufacture, and in particular relates to a rear axle assembly with horizontal multi-leaf leaf springs and balance bars. Background technique [0002] The rear axle assembly mainly includes two structural forms: the non-independent suspension rear axle and the independent suspension rear axle; among them, the structural characteristics of the non-independent suspension rear axle are: the left and right wheels are connected by an integral shaft, and then It is connected to the frame through the suspension; it has the problem of poor driving comfort, especially when driving on uneven roads, the left and right wheels affect each other, and the vehicle body is easy to tilt, which directly affects the driving comfort. The characteristics of the independent suspension rear axle are: each wheel is separately mounted on the body or the axle through a set of suspension, the axle is disconnect...
