Present common heavy motor vehicle double-front-axle steering transmission device, as shown in Figure 1, comprise the compositions such as steering box 2, steering gear bracket 3, the first axle steer Rocker arm 4, the first axle steer drag link 5, the first middle straight pull bar 6, intermediate rockers bearing 8, intermediate rockers 9, the second middle straight pull bar 10, the second axle rocker arm support 11, the second axle steer rocking arm 12, the second axle steer drag link 13, steering jack 15, power-assisted cylinder support 16.Be connected the first middle straight pull bar 6 between the first axle steer Rocker arm 4 and intermediate rockers 9, be connected the second middle straight pull bar 10 between intermediate rockers 9 and the second axle steer rocking arm 12, intermediate rockers 9 is fixed on support 1 by intermediate rockers bearing 8 and is arranged between first and second axle rocking arm, this kind structure is owing to having intermediate rockers and rocker arm support, the intermediate rockers two ends respectively connect a centre link, complicated structure, and number of parts is many, weight is large, and the trouble point is more.
The utility model content
For deficiency of the prior art, the utility model aims to provide a kind of designs simplification, reduces amount of parts, reduces the heavy motor vehicle double-front-axle steering assembly of drive gear of weight and cost.
In order to address the above problem, this kind heavy motor vehicle double-front-axle steering assembly of drive gear comprises: steering box, the first axle steer rocking arm, the first axle steer drag link, the second axle steer rocking arm, the second axle steer drag link and steering jack;
Steering box is fixed on vehicle frame by the steering box bearing, the output shaft of steering box is connected with the upper end of the first axle steer rocking arm, the lower end of the first axle steer rocking arm is connected with the upper arm that turns to of the first front axle via the first axle steer drag link, the middle-end of the second axle steer rocking arm is connected with steering jack, and the lower end is connected with the upper arm that turns to of the second front axle via the second axle steer drag link;
This heavy motor vehicle double-front-axle steering assembly of drive gear is characterised in that: also comprise a centre link, an end of this centre link is connected with the middle-end of the first axle steer rocking arm, and the other end is connected with the middle-end of the second axle steer rocking arm.
Preferably, the middle part of described centre link is arranged between bumper and automobile chassis frame through bending.
Preferably, the middle part of described centre link has bending part, and its eccentric throw is 0～100mm, and this centre link is that external diameter is the steel pipe of 40～60mm.
The beneficial effects of the utility model are: due to cancelled intermediate rockers, in connect rocker arm support, by a centre link, first and second axle steer rocking arm is connected, can be suitable for part heavy motor vehicle double-front-axle steering driving system, reach to fall and heavily fall cost, energy-conservation solution row, the purpose of raising client income.
Description of drawings
Fig. 1 is the structural representation of heavy motor vehicle double-front-axle steering assembly of drive gear of the prior art;
Fig. 2 is the structural representation of heavy motor vehicle double-front-axle steering assembly of drive gear of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
As shown in Figure 2, heavy motor vehicle double-front-axle steering assembly of drive gear of the present utility model, it comprises: steering box 2, the first axle steer Rocker arm 4, the first axle steer drag link 5, the second axle steer rocking arm 12, the second axle steer drag link 13, steering jack 15 and a centre link 18.
Concrete annexation is: steering box 2 is fixed on vehicle frame 1 by steering box bearing 3, the output shaft of steering box 2 is connected with the upper end of the first axle steer Rocker arm 4, the lower end of the first axle steer Rocker arm 4 is connected with an end of the first axle steer drag link 5, and the other end of the first axle steer drag link 5 is connected with the upper arm that turns to of the first front axle 7.The second axle steer rocking arm 12 has three taper holes, be fixed on vehicle frame 1 by the second axle rocker arm support 11, the taper hole of its middle-end is connected with steering jack 15, the taper hole of lower end is connected with an end of the second axle steer drag link 13, and the other end of the second axle steer drag link 13 is connected with the upper arm that turns to of the second front axle 14.Steering jack 15 is connected with vehicle frame 1 by power-assisted cylinder support 16.Centre link 18 is made by one whole steel pipe, and an end of centre link 18 is connected with the taper hole of the middle-end of the first axle steer Rocker arm 4, and the other end is connected with the taper hole of the middle-end of the second axle steer rocking arm 12.
