Abstract

The invention provides an automobile rear axle, which comprises an upper balance rod hinge seat, a lower balance rod hinge seat and a balance buffering mechanism. The balance buffering mechanism comprises an upper balance rod section, an elastic sleeve, a lower balance rod section, a telescopic rod, a compression spring and an extension spring. The upper balance rod section is pivoted to the upperbalance rod hinge seat; the elastic sleeve is fixed to the lower end face of the upper balance rod section; the lower balance rod section is pivoted to the lower balance rod hinge seat; the telescopic rod comprises a bulb portion, a round rod portion and a sleeve portion, the bulb portion is internally abutted against an inner conical hole of the elastic sleeve, the round rod portion penetrates the elastic sleeve and a limiting hole of the upper balance rod section, and the sleeve portion is movably arranged in a cavity of the lower balance rod section; the compression spring is stored in thecavity and abutted against the sleeve portion; the extension spring is connected to the upper balance rod section and the lower balance rod section. The automobile rear axle has advantages that a damping and buffering effect of the balance buffering mechanism in collision compression is enhanced, and the telescopic rod and the lower balance rod section can be protected from collision damages whenan automobile body is in collision.

Description

Technical field [0001] The invention relates to an automobile rear axle, in particular to an automobile rear axle. Background technique [0002] The automobile has become one of the most important means of transportation in the world. Its invention has greatly improved people's lives.
