Background technology
Steer drive is automobile steering power hub transmission, and it is delivered to the force and motion of deflector output the steering swivel of steeraxle, makes wheel flutter deflection, guarantees that wheel flutter deflection is by certain relationship change.At present two propons Vehicular turn driving systems, comprise the steering drop arm, a bridge drag link, middle front drag link, middle plumbing arm support, middle plumbing arm, rear middle straight pull bar, two bridge plumbing arms and the two bridge drag links that are connected with steering box assembly.
Due to what adopt, be middle plumbing arm support and the middle plumbing arm of welding structure, complex structure, manufacturing cost is also high, and the ball head structure that each drag link two ends are provided with simultaneously, comprises the parts such as upper and lower ball seat and spring, and assembling is complicated, and cost is higher simultaneously.Therefore, to two propons highway cars, need to be improved structure, be made more advantages of simple of propons Vehicular turn drive system structure, be reduced its cost.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of two propons Vehicular turn driving systems simple and reasonable, with low cost.
To achieve these goals, the technical scheme that the utility model is taked is:
Described pair of propons Vehicular turn driving system, comprise steering drop arm, one bridge drag link, drag link before middle, drag link after middle, two bridge plumbing arms and two bridge drag links, described steering box assembly, before a described bridge drag link and described centre, drag link is connected on described steering drop arm, behind described two bridge drag links and described centre, drag link is connected on described two bridge plumbing arms, also comprise the middle plumbing arm of solid forging structure and the middle plumbing arm support of solid forging structure, in the middle of described, plumbing arm support is fixed on vehicle frame, in the middle of described, plumbing arm upper end is arranged on described middle plumbing arm support, before described centre, behind drag link and described centre, drag link is arranged on described middle plumbing arm lower end.
Before a described bridge drag link, described centre, behind drag link, described centre, drag link and described two bridge drag links are provided with connecting ball head; Described connecting ball head comprises ball pin, outer spherical shell and elastic base, and described elastic base is fixing on the cover board, and described cover plate and described outer spherical shell are fixed; Described outer spherical shell and described elastic base form spherical hollow space, and described ball pin matches with described spherical hollow space, and in described ball pin, cover has dust boot.
Between described two bridge drag links and described vehicle frame, be connected with servo cylinder, described servo cylinder two ends are also provided with described connecting ball head.
Adopt technique scheme, need the accessory of assembling to greatly reduce, structure is advantages of simple more, cost has also reduced, and the middle plumbing arm support of the middle plumbing arm of solid forging structure and solid forging structure has reduced weight, improved intensity, made two propons Vehicular turn driving systems more reliable and more stable.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of pair of propons Vehicular turn driving system of the utility model;
Fig. 2 is the structural representation of connecting ball head in structure shown in Fig. 1.
Being labeled as in figure:
