[0001] The utility model belongs to the technical field of chassis of heavy-duty commercial vehicles, in particular to an integrated combined support for heavy-duty commercial vehicles. Background Art

[0002] The chassis of heavy-duty commercial vehicles is composed of multiple parts, such as the frame, front traction beam, pedal bracket, bumper bracket, intake system oil filter bracket, cab rear suspension system bracket, etc. Among them, the intake system oil filter bracket is used to position and install the intake system oil filter, and is connected and installed on the frame body through the transition mounting bracket to ensure the reliable stability of the oil filter installation; the cab rear suspension system bracket is used to support the installation of the cab rear suspension, so that the cab is suspended and installed on the frame through the transition mounting bracket (spring damping element), so as to achieve good shock absorption of the cab.

[0003] Traditionally, multiple single transition mounting brackets are used for connection. Each transition mounting bracket is designed separately, connected and installed with multiple brackets, and connected and installed on the frame. The function of each transition mounting bracket is relatively simple, and multiple transition mounting brackets need to be designed and installed to meet the functional requirements. This method of connecting multiple transition mounting brackets does not have an integrated design, and the connection structure is complex, the installation is cumbersome, the weight is heavy, the cost is high, the production efficiency is low, and it has a certain impact on the structural strength of the frame body.

[0004] As competition in the commercial vehicle industry becomes increasingly fierce, heavy-duty commercial vehicles have increasingly urgent demands for modularization, lightweighting, ease of installation, and a reduction in the number of parts in the overall vehicle layout. The traditional method of connecting multiple single-function transition mounting brackets cannot meet today's needs for commercial vehicle development. Utility Model Content

[0008] A further improvement of the utility model is that the support is in a U-shaped structure, and a support weight-reducing hole is formed in the middle thereof.

[0009] A further improvement of the utility model is that a fourth reinforcing rib is connected between the two cab rear suspension shock absorber mounting seats.

[0010] A further improvement of the utility model is that the fourth reinforcing rib is in a plate-like structure and extends in the same direction as the cab rear suspension shock absorber mounting seat.

[0011] A further improvement of the utility model is that the cab rear suspension bracket mounting seat includes three first mounting platforms with cylindrical structures in left and right directions, and the three first mounting platforms are connected and distributed in a triangle; the first mounting hole is opened in the middle of the first mounting platform.

[0012] A further improvement of the utility model is that the three first mounting platforms are connected at one side away from the frame body via a second reinforcing rib.

[0013] A further improvement of the utility model is that the two first mounting platforms on the upper side are connected by a third reinforcing rib on one side close to the frame body.

[0014] A further improvement of the utility model is that two sides of the top of the support extend upward to form first reinforcing ribs connecting the two first mounting platforms at the lower side.
