Abstract

The utility model discloses a heavy-vehicle balance suspension sliding rubber support base assembly comprising an upper connection plate, a middle support plate and a lower connection component. On the middle support plate is densely covered with sulfuration holes and between the upper and the lower connection plates is provided with a middle rubber body. On the top surface of the upper connection plate is provided with an upper connection rubber body. The upper connection plate, the middle support plate, the lower connection plate, the middle rubber body and the upper connection plate rubber body are vulcanized as a whole. The utility model makes full use of elasticity of the rubber body so as to greatly enhance anti-impulsion and smoothness of the vehicle. In addition, the utility model intensifies the comfort of the passenger and lowers the damage ratio of goods. Moreover, the adoption of steel plate spring and frame can greatly relive bearing force of the vehicle bridge, thus, the service life could be enhanced and vibration noise could be reduced when the vehicle is running without load.

Description

A kind of heavy-duty car equalizing type of suspension slip neoprene bearing assembly

(1) technical field

The utility model relates to the neoprene bearing assembly that a kind of automobile is used, particularly a kind of slip neoprene bearing assembly that is applicable to the heavy-duty car equalizing type of suspension.

(2) background technique

The elastic vibration clamper of heavy-duty car equalizing type of suspension is generally leaf spring, and leaf spring two ends and the spring slide plate rigidity that is fixed on the vehicle bridge are slidingly connected.When automobile when tire runs into obstacle in the process of moving, spring slide plate and leaf spring are done rigid collision, so the impact that vehicle frame is subjected to is bigger, vehicle running smoothness is poor, so just causes occupant's travelling comfort to descend, and the impaired possibility of goods increases, the leaf spring life-span reduces, and noise is bigger when unloaded.

(3) summary of the invention

The technical problems to be solved in the utility model is: a kind of good damping result, long service life are provided, can greatly improve the heavy-duty car equalizing type of suspension slip neoprene bearing assembly of vehicle running smoothness.

In order to solve the problems of the technologies described above, the utility model comprises upper junction plate, intermediate support plate and following link, be densely covered with the sulfuration hole on the intermediate support plate, between upper junction plate and the following link intermediate rubber body is arranged, the upper junction plate rubber body is arranged on the end face on the upper junction plate, and upper junction plate, intermediate support plate and following link, intermediate rubber body and upper junction plate rubber body are sulfided into one.

For convenience being connected of the utility model and axle housing, on four angles of described time link a connecting thread hole is arranged respectively.

For convenience being connected of the utility model and leaf spring, prevent that leaf spring from skidding off the utility model and causing the accident, downward flange before and after the described upper junction plate, about to upper overturning.

The beneficial effects of the utility model are: the utility model has made full use of the elasticity of rubber body, thereby the impact resistance of vehicle and smoothness are improved greatly.Strengthened occupant's travelling comfort; Reduced the probability of damage of goods; And because the force-bearing situation of use leaf spring of the present utility model and vehicle frame, vehicle bridge improves greatly; Thereby improved its working life; Reduced the vibrating noise when automobile is unloaded; At present, the upper junction plate of most of neoprene bearing is connected with bolt with leaf spring, compare with this neoprene bearing the utility model stressed simple, the life-span long and assembling is safeguarded all simple.

(4) description of drawings

Fig. 1 is structural representation of the present utility model (half cut-away view);

Fig. 2 is the plan view of Fig. 1;

Wherein: 1, upper junction plate flange, 2, the upper junction plate rubber body, 3, upper junction plate, 4, intermediate support plate, 5, the sulfuration hole, 6, the intermediate rubber body, 7, positioning hole, 8, the connecting thread hole, 9, link down.

(5) embodiment

A kind of specific embodiment as depicted in figs. 1 and 2, it comprises upper junction plate 3, intermediate support plate 4 and following link 9, be densely covered with sulfuration hole 5 on the intermediate support plate 4, between upper junction plate 3 and the following link 9 intermediate rubber body 6 is arranged, upper junction plate rubber body 2 is arranged on the end face on the upper junction plate 3, upper junction plate 3, intermediate support plate 4 and following link 9, intermediate rubber body 6 and upper junction plate rubber body 2 are sulfided into one, on four angles of following link 9 a connecting thread hole 8 is arranged respectively, upper junction plate 3 is provided with upper junction plate flange 1, upper junction plate flange 1 is the downward flange in upper junction plate 3 front and back, about to upper overturning.

Upper junction plate 3 of the present utility model, following link 9 and intermediate support plate 4 at first are processed into the shape as figure, then the three is put into the mould vulcanized rubber, make three and upper junction plate rubber body 2 intermediate rubber bodies 6 be sulfided into one, join strength of the present utility model has been improved in the sulfuration hole 5 of gathering on the intermediate support plate 4.Whole sulfuration back making of the present utility model has just been finished.During assembling, there are 4 to link tapped hole 8 on the link 9 down of the present utility model, at first the utility model are fixed on the axle housing, put into the location of locating stud realization and axle housing in the positioning hole 7 in the time of fixedly in the middle of following link 9 bottoms with bolt; Vulcanizing one deck upper junction plate rubber body 2 on the upper junction plate 3 of the present utility model, the leaf spring end directly is pressed in to be realized on the upper junction plate rubber body 2 being slidingly connected, for preventing that the leaf spring end from skidding off upper junction plate rubber body 2, is provided with upper junction plate flange 1 in the left and right sides of upper junction plate 3.

When wheel ran into obstacle in the vehicle driving process, axle tramp brought impact, and the utility model so hit energy during at first absorption portion is dashed, plays buffering and damping effect owing to have good elasticity; Leaf spring carries out secondary buffer and vibration damping again, further absorbs impact energy.Vehicle has just possessed the secondary vibration-damping function like this, compares with original spring skateboard, has improved occupant's travelling comfort and vehicle ride comfort greatly, has reduced the impaired probability of goods; Prolong correlated parts working life, improved vehicle economy; Owing on upper junction plate 3, vulcanizing one deck upper junction plate rubber body 2, so the vibrating noise when having reduced the vehicle Ballast again.
