Description
Technical field
The utility model belongs to vehicle part, particularly wheel suspension system before a kind of two front fulcrum rocker-arms of cross-country car.
Background technology
Cross-country car is commonly called as all-terrain vehicle or beach buggy owing to travel on the height great road environment of drop that rises and falls usually, and is therefore comparatively harsh for the requirement of suspended structure, in the hope of beating of fully absorbing Uneven road and produced.Wherein front-wheel has the function of turning in addition, therefore, for the more careful requirement of need of suspended structure of shock-absorbing, otherwise very easily influences the stability of driving a vehicle.
As shown in Figure 1, the front-wheel suspended structure of existing all-terrain vehicle is single A-frame arm suspended structure, it mainly is that two base portions 61 with single A-frame arm support 6 one ends are articulated on the default carrier base 51 of 5 liang of sides of vehicle frame, and make of the two side horizontal expansions of single A-frame arm support 6 to vehicle frame, single A-frame arm support 6 other ends then are provided with the pivot hole 62 that up/down perforation extends, and can stretch into to form with default head lamp brush guard pivot 73 for axle block 7 to articulate.Axle block 7 is respectively equipped with the wheel shaft 71 of wheel 9 pivot joints of buying car in installments and inserts the pull bar convergence hole 72 that articulates for the pivot 531 that does not have in advance on the steering track rod 53 in vertical direction.On the vehicle frame 5 the action of hand-drive steering track rod 53, with turning to of control wheel shaft 71 and wheel 9, and single A-frame arm support 6 stage casings are provided with midship mounting 63 in addition, midship mounting 63 cooperates the Shock absorber seat 54 of being located at vehicle frame 5 both sides carrier bases 51 tops in conjunction with Shock absorber 55, utilizes Shock absorber 55 to absorb the oscillating stroke of single A-frame arm support 6.
Yet, as Fig. 2, shown in Figure 3, when vehicle ' in rugged road surface, wheel 9 rises and falls when driving single A-frame arm support 6 and teetering with ground, because the steering shaft angle can swing and change along with single A-frame arm support 6, so front wheel tread d1 ≠ d1 ' not only, and leaning angle also with change, and, cause the angle of toein that in the shock-absorbing stroke, is difficult to keep front-wheel owing to wheelspan, leaning angle can change with single A-frame arm support 6 swings, cause the stability of vehicle not good.And above-mentioned phenomenon can increase and worsen along with shock-absorbing stroke (being single A-frame arm support 6 pendulum angles), and therefore, the shock-absorbing stroke of traditional single A-frame arm suspended structure is unsuitable long.
As shown in Figure 4, two A-frame arm suspended structures mainly are that two sides in vehicle frame 50 are arranged with upper bracket seat 501 that the higher base portion 801 of keeping supplying A-frame arm support 80 articulates and the low lower bracket seat 502 that articulates for A-frame arm support 60 base portions 601 down, down, last A-frame arm support 60,80 two side horizontal expansions to vehicle frame 50, wherein descend the stage casing of A-frame arm support 60 to be provided with midship mounting 603, midship mounting 603 cooperates the Shock absorber seat 504 of being located at upper bracket seat 501 tops, vehicle frame 50 both sides in conjunction with Shock absorber 505, and on, following A-frame arm support 80,60 the other end then is articulated in the two ends up and down of connecting base 81.Be provided with the pivoted hole 810 that up/down perforation extends in connecting base 81 stage casings, pivoted hole 810 can stretch into pivot joint for defaulting in axle block 70 head lamp brush guard pivots 703.Axle block 70 is respectively equipped with the wheel shaft 701 of wheel 9 pivot joints of buying car in installments and inserts the pull bar convergence hole 702 that articulates for defaulting in steering track rod 503 head lamp brush guard pivots 5031 in horizontal direction.On the vehicle frame 50 the action of hand-drive steering track rod 503, with turning to of control wheel shaft 701 and wheel 9.
As Fig. 5, shown in Figure 6, the steering shaft angle of the two A-frame arm suspended structures of this kind can be different and change along with the length of upper and lower A-frame arm support 60,80 and installing angle, so its leaning angle can be controlled on demand.But when vehicle ' in rugged road surface, wheel 9 rises and falls with ground upper and lower A-frame arm support 60,80 is teetered, and makes its front wheel tread d2 ≠ d2 ', and its angle of toein also is easy to change in the shock-absorbing stroke, causes the stability of vehicle not good.
