Description

Technical Field

[0001] This invention relates to a vehicle frame mounting structure, and more particularly to a rear suspension mounting assembly for a vehicle frame. Background Technology

[0002] Currently, to maintain stability and safety, vehicle frames typically use various bridges connected together by connectors or welding. This results in relatively long bridges, making the vehicle body appear bulky. Furthermore, the internal structure of the frame is quite complex, with limited usable space. The overall layout of the frame is noticeably irregular, and the connections are also quite complex, affecting production efficiency. Moreover, since these bridges are themselves welded components, the welding deformation itself causes significant and difficult-to-control errors, thus affecting the assembly quality of the vehicle. At the same time, the machining precision requirements for the rear axle are also quite high. Summary of the Invention

[0003] This invention provides a rear suspension mounting assembly for a vehicle frame, which reduces the difficulty of machining the parts themselves and assembling the vehicle.

[0004] This invention adopts the following technical solution: a rear suspension mounting assembly for a vehicle frame, comprising a frame structure, the frame mainly including a horizontally placed integral upper mounting bracket and a horizontally placed lower mounting bracket, both the upper and lower mounting brackets being integral frame structures; a vertical mounting seat is fixedly provided at the front of the lower mounting bracket, a lateral stabilizer bar component is mounted at the front of the mounting seat; a front support member is provided between the front of the upper mounting bracket and the top of the mounting seat; a vertical rear support seat is provided between the rear of the upper mounting bracket and the rear of the lower mounting bracket; and the vehicle frame and... The mounting base has a left independent suspension system and a right independent suspension system installed on both sides. The left independent suspension system mainly includes a left rear rocker arm assembly and a left shock absorber, and the right independent suspension system mainly includes a right rear rocker arm assembly and a right shock absorber. The left and right rear rocker arm assemblies are symmetrically installed on the left and right sides of the mounting base. The left shock absorber is installed between the left rear rocker arm assembly and the middle of the left side of the upper mounting bracket, and the right shock absorber is installed between the right rear rocker arm assembly and the middle of the right side of the upper mounting bracket. The left and right shock absorbers are symmetrically arranged.

[0005] Furthermore, the front end of the left rear rocker arm component is provided with a left shaft sleeve. After the left rocker arm shaft passes through the left shaft sleeve, it extends into the left connecting hole provided on the left side of the mounting base. The left rocker arm shaft is fixedly connected to the left side of the mounting base by the left locking nut. The left rear rocker arm component rotates around the left rocker arm shaft. The top connecting end of the left shock absorber is connected to the left connecting seat at the middle position on the left side of the upper mounting bracket, and the bottom connecting end of the left shock absorber is connected to the middle position of the left rear rocker arm component.

[0006] Furthermore, the front end of the right rear rocker arm component is provided with a right bushing. After the right rocker arm shaft passes through the right bushing, it extends into the right connecting hole provided on the right side of the mounting base. The right rocker arm shaft is fixedly connected to the right side of the mounting base by the right locking nut. The right rear rocker arm component rotates around the right rocker arm shaft. The top connecting end of the right shock absorber is connected to the right connecting seat at the middle position on the right side of the upper mounting bracket. The bottom connecting end of the right shock absorber is connected to the middle position of the right rear rocker arm component.

[0007] Furthermore, both the upper and lower mounting brackets of the overall structure are made of square cast tubing.

[0008] Furthermore, the front support, rear support base, and mounting base are all made of cast material.

[0009] Furthermore, the left and right ends of the lateral stabilizer bar component are connected to the front of the mounting base via a left ball joint and a right ball joint, respectively.

[0010] Furthermore, the front connecting pipe at the front and the rear connecting pipe at the rear of the mounting frame have reinforcing ribs. Both the front and rear connecting pipes are square cast pipes, and triangular support blocks are provided on both sides of the rear connecting pipe between it and the upper mounting frame.

[0011] The present invention has the following beneficial effects: After adopting the above technical solutions, the components of the frame of the present invention are basically integral structures, requiring fewer assembly parts during installation. Most parts are directly connected via connectors, making the installation of the independent suspension system more convenient. This makes the overall assembly of the present invention easier, greatly reducing assembly difficulty and the processing difficulty of the components themselves. Due to the smaller number of assembly parts, cumulative deviations caused by assembly are also reduced. Since the present invention involves very few welding connections, and the frame components and connectors are all made of casting materials, errors caused by welding deformation are prevented, effectively controlling welding deformation, resulting in smaller welding deformation, reduced manufacturing difficulty, and improved processing accuracy. The upper and lower mounting frames of the present invention are both made of square cast tubing. The front support, rear support seat, and mounting seat are all made of casting materials. The front connecting tube at the front and the rear connecting tube at the rear of the mounting frame have reinforcing ribs. Both the front and rear connecting tubes are square cast tubing, and triangular support blocks are provided on both sides of the rear connecting tube between it and the upper mounting frame, which improves the stability and strength of the frame. The invention features a left independent suspension system and a right independent suspension system on each side, which can meet the driving requirements of various rough roads. Furthermore, the invention employs a dual shock absorber structure, which improves vehicle load capacity. The structure of the invention is relatively simple, resulting in a larger usable space within the frame, which is beneficial for the placement of the fuel tank and leads to a more rational overall vehicle layout.
