Problems solved by technology

But the disadvantage is that due to the cancellation of the central bolt, the rubber seat cannot limit the separation movement of the axle housing and the frame, so mechanisms such as limit chains must be added, which in turn makes the overall structure more complicated and the cost increases

Embodiment Construction

[0023] In order to clearly illustrate the technical features of the solution, the solution will be described below through a specific implementation manner.

[0024] As shown in the accompanying drawing, a heavy-duty vehicle rear suspension shock-absorbing elastic body assembly includes a slide plate 1, an elastic body 2, and a lower plate 3. Clamping, the elastic body 2 is assembled in the space formed by the slide plate 1 and the lower plate 3 .

[0025] The elastic body 2 includes 3-5 layers of steel plates, and there is a polymer elastic layer between adjacent steel plates. The polymer elastic layer is vulcanized together with the steel plates through a vulcanization process. The outer flange 16 is in contact with the sides of the slide plate 1 and the lower plate 3 respectively and reliably clamps the contact surfaces.

[0026] The slide plate 1 includes an upper frame part and a lower frame part, the upper frame part has a longitudinal installation hole 4, the lower sur...

Abstract

An elastomer assembly for shock absorption of a heavy truck rear suspension is disclosed. According to the technical scheme, the assembly for shock absorption of the heavy truck rear suspension comprises a sliding plate, an elastomer and a lower plate; the lower end of the sliding plate is clamped with the upper end of the lower plate through mutually matched limiting structures; and the elastomer is assembled in a space formed by the sliding plate and the lower plate. The elastomer assembly has the functions of shock absorption and buffering; an original shock absorption effect of the elastomer assembly is guaranteed, and compared with the original structure, the weight of the elastomer assembly is reduced and the service life of the whole assembly is prolonged; besides, the production cost is reduced and new functions are added; and the elastomer assembly is simple and convenient in both aspects of assembly and repair.

Description

technical field [0001] The invention relates to an elastic body assembly for shock absorption of the rear suspension of a heavy-duty vehicle. Background technique [0002] The structure of the traditional heavy-duty vehicle balance rear suspension is mostly an integral balance shaft, the upper and lower thrust rods are straight rods, and the end is slidingly connected to the leaf spring bracket for support, and only the leaf spring is the first level of shock absorption. Since the upper and lower thrust rods are straight rods, the lateral positioning function of the vehicle is poor. Steyr's traditional leaf spring bracket is a semi-closed form, and later added a self-limiting function, and the leaf spring bracket becomes a rectangular closed frame structure. The more advanced balanced rear suspension is generally equipped with left and right independent balance shafts, V-shaped thrust rods are positioned, and elastic shock absorbers are generally leaf springs and rubber sea...
