Front axle assembly of automobile drum brake

Abstract

The invention discloses a front axle assembly of an automobile drum brake. The front axle assembly comprises a front shaft (1); the front axle assembly is characterized in that one or multiple hollow holes (2) are formed in a web plate of the front shaft (1), the other side of a steering knuckle (3) is provided with a horizontal arm (9), a middle hinging shaft hole (16) is formed in the middle part of the horizontal arm (9), a pulling rod connecting hole (15) is formed in one end of the horizontal arm (9), an auxiliary connecting shaft hole (17) is formed in the other end of the horizontal arm (9), and a weight reduction notch (18) is formed in a horizontal arm body between the middle hinging shaft hole (16) and the auxiliary connecting shaft hole (17); and weight reduction gaps (19) are formed between adjacent bolt holes in the outer edge of a brake hub (5). According to the front axle assembly of the automobile drum brake, disclosed by the invention, improved design on structures of the steering knuckle and a transverse pulling rod is achieved, the use performance is improved, weight reduction on main parts are also effectively realized, the requirement on lightweight design is met, the integrated weight of an automobile front axle is reduced, and the automobile traveling performance is beneficial for being increased.

Description

technical field [0001] The invention relates to a front axle assembly, in particular to an automobile drum brake front axle assembly, which belongs to the technical field of automobile parts. Background technique [0002] The front axle of the car belongs to the chassis part of the car and is the main load-carrying part of the car. The existing drum brake front axle has been optimized and improved less. Many main components of the existing drum brake front axle are relatively heavy. Heavy and lightweight design is not conducive to improving the driving performance of the car. In addition, the existing steering knuckle has many lubricating and sealing parts, and the cost of tooling and installation are relatively large, and the lubricating effect is not good, and the use and maintenance are inconvenient. Contents of the invention [0003] The purpose of the present invention is to solve the problem that the overall weight of the front axle assembly of the existing drum bra...
