Description

Technical Field

[0001] This utility model relates to the field of automobile manufacturing technology, and in particular to a front suspension mounting platform for a medium-sized passenger vehicle. Background Technology

[0002] The following problems exist in the traditional process of installing the front stabilizer bar and front stabilizer bar linkage in the front suspension of automobiles:

[0003] 1. When installing the front suspension, the front suspension springs need to be compressed to a certain length before the front stabilizer bar and front stabilizer bar linkage can be installed. Compressing the front suspension springs is difficult and time-consuming.

[0004] 2. During the compression of the front spring, positioning and fixing the front crossbeam assembly is time-consuming and labor-intensive.

[0005] Based on this, in order to solve the problems of installation stability of the front suspension of automobiles and time-saving and labor-saving positioning of the front suspension, this design proposes a mounting platform for the front suspension of a medium-sized passenger vehicle. Utility Model Content

[0006] The purpose of this utility model is to provide a front suspension mounting platform for a medium-sized passenger vehicle.

[0007] A front suspension mounting platform for a medium-sized passenger vehicle includes: a support and cylinders, wherein the support structure is a cuboid frame structure, the support is welded from steel plates, cylinders are installed on both sides of the support, and a support plate assembly is fixed on the upper surface of the support.

[0008] Preferably, chain hook assemblies are hooked on the left and right sides of the support. The chain hook assembly consists of a chain and a hook. One end of the chain hook assembly is connected to a steel bar. A pressure plate is installed in the middle of the steel bar. The other end of the chain hook assembly is hooked on the steel plate of the support.

[0009] Preferably, U-bolts are fixed on the left and right sides of the support, and the chain hook assembly is hooked on the U-bolts.

[0010] Preferably, a cylinder top fixing component is installed on the upper part of the cylinder, a nylon sleeve is installed on the upper part of the cylinder top fixing component, and a cylinder bottom fixing component is installed on the lower part of the cylinder, and the cylinder bottom fixing component is fixed to the bottom of the support.

[0011] Preferably, the support plate assembly is welded from steel pipes and steel plates, and the support plate assembly is provided with a forearm fixing pin and a crossbeam positioning pin assembly.

[0012] The beneficial effects of the above scheme are:

[0013] 1. This utility model relates to a front suspension mounting platform for passenger vehicles. The front crossbeam assembly is positioned and fixed on the platform using positioning pins and circular pressure plates. Two two-position five-way manual valves are used to adjust and control the speed and extension amount of the cylinder, so that the cylinder lifts the left and right lower control arms. The front suspension spring is compressed to a suitable length before the front stabilizer bar and front stabilizer bar connecting rod are installed. This reduces the fixing and positioning time during the assembly of the front crossbeam assembly; it also saves time and effort during the compression process of the front spring.

[0018] The present invention will be further described clearly and completely below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited thereto.

[0019] according to Figure 1 , Figure 2 , Figure 3 As shown, a front suspension mounting platform for a medium-sized passenger vehicle includes: a support 1 and a cylinder 11. The support 1 has a rectangular frame structure and is welded from steel plates. Cylinders 11 are installed on both sides of the support 1, and a support plate assembly 8 is fixed on the upper surface of the support 1.

[0020] Specifically, chain hook assemblies 2 are hooked on the left and right sides of the support 1. The chain hook assembly 2 consists of a chain and a hook. One end of the chain hook assembly 2 is connected to a steel bar 3. A pressure plate 4 is installed in the middle of the steel bar 3. The other end of the chain hook assembly 2 is hooked on the steel plate of the support 1.

[0021] Specifically, U-bolts 5 are fixed on the left and right sides of the support 1, and the chain hook assembly 2 is hooked on the U-bolts 5.

[0022] Specifically, a cylinder top fixing member 10 is installed on the upper part of the cylinder 11, a nylon sleeve 9 is installed on the upper part of the cylinder top fixing member 10, and a cylinder bottom fixing member 12 is installed on the lower part of the cylinder 11. The cylinder bottom fixing member 12 is fixed to the bottom of the support 1.

[0023] Specifically, the support plate assembly 8 is welded from steel pipes and steel plates, and the support plate assembly 8 is provided with a forearm fixing pin 6 and a crossbeam positioning pin assembly 7.

[0024] Working principle:

[0025] A mounting platform for the front suspension of a medium-sized passenger vehicle includes a support 1 and a cylinder 11. During operation, the crossbeam of the front suspension is placed on a support plate assembly 8. The front arm fixing pin 6 and the crossbeam positioning pin assembly 7 ensure the front suspension is stable on the support plate assembly 8. The cylinder 11 then lifts the front suspension, compressing the spring. Once the spring is compressed to a certain extent, a chain hook assembly 2 further secures and limits the front suspension, preventing it from popping out during the spring compression process. Subsequently, the stabilizer bar and stabilizer bar linkage are installed. This process is time-saving and labor-saving, enabling stable and safe installation of the stabilizer bar and stabilizer bar linkage, greatly improving installation efficiency.
