Problems solved by technology

[0007] From the above scheme, it can be seen that in the relevant patents of the steering drive axle, on the one hand, the main consideration is an independent design of the steering drive axle, or the scheme of the steering drive wheel, or changing the steering axle into a steering drive axle These solutions are not suitable for refitting existing drive axles into steering drive axles. They have poor versatility and are not suitable for improving existing technologies. difficulty

Embodiment 2

[0057] The difference between this embodiment and embodiment 1 is: as Figure 8-10 As shown, the upper steering knuckle 5 and the lower steering knuckle 6 are bolted and fixed on the axle housing 1. Specifically, the upper steering sub-member 52 and the lower steering sub-member 62 are respectively provided with an upper steering knuckle fixing part 55 and a lower steering sub-member 62 at the position connecting the axle housing 1. The lower steering knuckle fixing part 65, the upper steering knuckle fixing part 55 and the lower steering knuckle fixing part 65 are respectively provided with arc surfaces matching the outer circumference of the axle housing 1. After the upper steering sub-member 52 and the lower steering sub-member 62 are installed in place, the upper steering The arc surfaces of the knuckle fixing part 55 and the lower steering knuckle fixing part 65 are attached to the axle housing 1, and the upper steering knuckle fixing part 55 and the lower steering knuckle...

Abstract

The invention relates to an automobile rear shaft steering drive axle which comprises a rear shaft (2) provided with a shaft housing (1). The two ends of the rear shaft (2) and the two ends of the shaft housing (1) are connected with automobile hubs (3) respectively. The two ends of the axle shaft (2) and the two ends of the shaft shell (1) are cut off at a set distance from the hubs. The rear shafts (2) on the two sides of the cross section are connected through ball cage type universal joints (4) at the two cut-off positions respectively. Steering knuckle assemblies are arranged on the outersides of the shaft housing (1) between the universal joints and the hubs respectively. Each steering knuckle assembly comprises an upper steering knuckle (5) and a lower steering knuckle (6) which are coaxially arranged, the upper steering knuckles (5) and the lower steering knuckles (6) are movably installed on a frame, and the lower steering knuckles (6) are further connected to a steering gearthrough trapezoidal arms (7). Compared with the prior art, the automobile rear shaft steering drive axle is simple in structure and wide in applicability, a drive axle is easily transformed into a steering drive axle, and rear shaft steering is achieved.

Description

technical field [0001] The invention relates to an automobile component, in particular to an automobile rear axle steering drive axle. Background technique [0002] At present, four-wheel steering technology is developing rapidly. It is not only widely used in high-end models, but also gradually develops in order to expand the market, improve market competitiveness, and strive for greater market share. And the independent steering axle can not meet the demand of four-wheel steering technology, and it becomes a necessary technology to convert the drive axle into a steering drive axle. At present, there is a lack of a widely-used drive axle on the market to convert it into a steering drive axle, and it cannot adapt to the actual needs of various types of vehicles. [0003] Chinese patent CN109436166A discloses a driving and steering mechanism for baby carriages. This scheme is mainly aimed at the wheels of children's carriages that can only be driven but not turned. Two rods ...
