Embodiment 1

[0041] Such as Figure 6 .7 shows a heavy-duty vehicle rubber bearing and leaf spring bracket assembly 3, including a rubber bearing 2 and a leaf spring bracket 1, the leaf spring bracket 1 is in a closed frame structure, and the rubber bearing 2 is installed in the frame structure within the cavity.

[0042] Such as Figure 4The rubber support 2 shown in .5 includes an upper end plate 14, a lower end plate 21, and an intermediate plate 16 and an intermediate plate 19 between the upper end plate 14 and the lower end plate 21. They are parallel curved surfaces, and the rubber body 15 Vulcanized as one.

[0043] A layer of rubber body 13 is also vulcanized on the upper end plate 14 to reduce the noise of the vehicle when it is unloaded.

[0044] In order to optimize the force on the front and rear of the rubber bearing 2, downward flanges 17 are provided on the front and rear sides of the upper end plate 14, and upward flanges 18 are provided on the front and rear sides of the...

Embodiment 2

[0051] Such as Figure 10 . The leaf spring support 1 shown in 11 is a semi-closed frame structure, and the other parts are the same as in the first embodiment.

Embodiment 3

[0053] Cancel the bottom limit mounting surface 10 of the leaf spring support 1, and directly install the bottom limit block 26 on the lower wing surface of the vehicle frame to realize the limit, as Figure 8 There are two threaded holes on the bottom limit block 26 shown in .9, and the two threaded holes and the lower wing surface of the lower frame are fixed by bolts to realize the limit, and the other parts are the same as in Embodiment 1.

[0054] In the above embodiment, the rubber body 13 can be omitted on the upper end plate 14 of the rubber bearing 2 .

Abstract

The invention relates to an assembly of a rubber bearing and a leaf spring supporting frame of a heavy truck, which consists of a rubber bearing and a leaf spring supporting frame. The leaf spring supporting frame is a closed or semi-closed frame structure; the rubber bearing is arranged in cavity of the frame structure. The rubber bearing consists of an upper end plate, a lower end plate and a rubber body between the upper end plate and the lower end plate. The upper surface of the upper end plate is circular arc-shaped; the lower end plate is connected with the leaf spring supporting frame. A side limiting working face used for limiting with a side limited block is arranged on a plane of the leaf spring supporting frame; an underside limiting installing plane used for assembling with an underside limited block is arranged in the inner side of the leaf spring supporting frame; the underside limiting installing plane is provided with two threaded holes. The assembly has simple assembly and maintenance and can reduce maintenance cost and simultaneously improve maintenance quality and security of maintenance personnel and increase reliability and economy of the whole vehicle. The side and underside double limiting structure improves limiting reliability, thereby avoiding interference of components and effectively protecting the frame and drive axle housing.

Description

(1) Technical field [0001] The invention relates to the technical field of a rubber bearing and leaf spring bracket assembly for automobiles, in particular to a sliding type heavy-duty automobile rubber bearing and leaf spring bracket assembly suitable for the balanced rear suspension of heavy engineering vehicles. (2) Background technology [0002] The structure of the traditional heavy-duty vehicle balanced rear suspension is mostly an integral balance shaft, the upper and lower thrust rods are straight rods, the leaf spring is a first-level shock absorber, and the end is slidably connected to the leaf spring bracket for support. Since the upper and lower thrust rods are straight rods, the vehicle's lateral positioning function is poor. In order to prevent the left and right displacement of the drive axle, it is necessary to rely on leaf springs, guide plates and leaf spring brackets to limit the lateral movement of the axle. Steyr's traditional leaf spring bracket is a se...
