Description

New multifunctional push-down support assembly

technical field

The utility model relates to heavy-duty truck parts, in particular to a novel multifunctional push-down support assembly.

Background technique

As the main bearing system of the vehicle, the rear suspension assembly is related to the safety, comfort and handling stability of the vehicle. Among them, the leaf spring, thrust rod assembly and stabilizer bar respectively realize vertical load bearing, transmission Longitudinal force and moment, the function of preventing excessive lateral inclination of the vehicle body. However, the structure of the rear suspension is relatively complicated and the space is relatively narrow, which brings inconvenience to the arrangement of other parts of the vehicle; at the same time, in order to meet the interconnection of various parts inside the suspension system, more parts need to be designed. This leads to an increase in the assembly process, an increase in the weight and cost of the product, and it also brings a lot of inconvenience to future maintenance. This is in contradiction to the design concept of reducing costs and improving quality pursued by modern heavy-duty trucks.

Utility model content

Aiming at a series of problems such as the narrow assembly space, complex assembly process, low assembly efficiency, and inconvenient after-sales service of the existing heavy-duty truck rear suspension assembly, the utility model proposes a simple structure, high reliability, low weight and low cost. Low profile, easy to assemble new multifunctional push-down support assembly.

In order to achieve the above object, the utility model adopts the following technical solutions:

The new multifunctional push-down support assembly includes a push-down support, a rubber bearing and a bearing cover; the bearing cover is fastened to the push-down support by bolts; the push-down support is assembled with the lower thrust rod through bolts The push-down support is assembled to the lower plane of the rear axle through the positioning pin, the rubber bearing is assembled with the stabilizer bar assembly, and the bearing cover presses the rubber bearing for positioning; the push-down support passes through the rubber bearing and the stabilizer bar The assembly is set apart.

When the utility model is in use, firstly, the push-down support is assembled on the lower plane of the rear axle through the positioning pin, and the positioning pin hole is guaranteed to be clean, free of sundries, and coated with anti-rust oil before assembly; the push-down support and The connecting part of the stabilizer bar assembly is located at the rear to prevent wrong installation; four bolts and four nuts are used to fasten the push-down support and the rear axle through the mounting holes of the rear axle.

The bolt connects the lower thrust rod assembly to the push-down support through the mounting hole of the lower thrust rod assembly. The ball head of the lower thrust rod assembly is behind the push-down support; it must be tightened according to the specified tightening torque to avoid Fracture occurs under impact load;

The stabilizer bar assembly is first assembled with the rubber bearing, then pressed and positioned by the bearing cover, fastened to the push-down support by bolts and nuts, and tightened. Note that scratches on the rubber bearing should be avoided during the assembly process. injury etc.

This realizes the connection between the new multifunctional push-down support assembly and other related parts. In order to ensure the assembly quality and service life of the product, it is necessary to ensure that the tightening torque of each fastener meets the requirements and regular inspection.

Each one of the utility model left and right during loading is a symmetrical piece.

The beneficial effects of the utility model are:

1. The push-down support in the utility model is separated from the stabilizer bar assembly through the rubber bearing, which avoids dry friction between the metal parts; It has the function of buffering vibration and reducing noise;

2. Adopting a new type of combined bracket assembly connection method, the axle assembly, lower thrust rod assembly and stabilizer bar assembly of the rear suspension of the car are closely connected as one, which not only improves the overall connection strength of the assembly, The installation space of the rear suspension is saved, the movement interference between the assemblies is avoided, the assembly process is reduced, and the assembly efficiency is improved.

3. Due to the reduction of the number of connecting parts, the cost is reduced.

4. The connection between the multifunctional push-down support assembly and the push-down rod assembly realizes the transmission of longitudinal force and moment and ensures the normal running of the vehicle; the connection with the transverse stabilizer bar assembly improves the roll of the vehicle Stiffness, which prevents the car from tilting laterally when turning.

Among them, 1. Push down support, 2. Bearing cover, 3. Rubber bearing, 4. Hexagon head bolt, 5. Self-locking nut, 6. Locating pin hole, 7. Rear axle installation hole, 8. Lower thrust rod assembly 9, lower thrust rod assembly, 10, stabilizer bar assembly, 11, positioning pin, 12, rear axle.

Detailed ways

A novel multifunctional push-down support assembly is mainly composed of a push-down support 1, a rubber bearing 2 and a bearing cover 3.

It can be seen from Fig. 1, Fig. 2 and Fig. 3 that the push-down support 1 is assembled on the lower plane of the rear axle 12 through the dowel pin 11, and the dowel pin hole 6 must be clean and free of debris before assembly, and coated with Anti-rust oil; the part where the push-down support 1 is connected with the stabilizer bar assembly 10 is at the rear to prevent installation in the wrong direction; use four bolts and four nuts to realize the push-down support 1 and the rear Fastening constraints of the bridge 12.

The bolt connects the lower thrust rod assembly 9 to the push-down support 1 through the installation hole 8 of the lower thrust rod assembly, and the ball head of the lower thrust rod assembly 9 is behind the push-down support 1; the tightening torque must be specified Tighten it tightly to avoid the breakage of the bolt when it is subjected to impact load;

The stabilizer bar assembly 10 is first assembled with the rubber bearing 3, then pressed and positioned by the bearing cover 2, fastened to the push-down support 1 through the bolt 4 and nut 5, and tightened, pay attention to the assembly process Damage such as scratches to the rubber bearing 3 should be avoided.

Since the stabilizer bar assembly 10 and the push-down support 1 are separated by the rubber bearing 3, this avoids dry friction between the metal parts; 3 It also has the function of buffering vibration and reducing noise.

This realizes the connection between the new multifunctional push-down support assembly and other related parts. In order to ensure the assembly quality and service life of the product, it is necessary to ensure that the tightening torque of each fastener meets the requirements and regular inspection.

Described novel multifunctional push-down support assembly, each one on the left and right when loading, is a symmetrical piece.
