Description

Technical Field

[0001] The utility model relates to the technical field of vehicle suspension systems, in particular to an integrated rear suspension lower support for a commercial vehicle cab. Background Art

[0002] The rear suspension lower support of the commercial vehicle cab is a crucial component in the vehicle suspension system. It is not only a bridge that firmly connects the cab and the chassis, but also a key factor in ensuring the stability and ride comfort of the cab. During driving, the rear suspension lower support can effectively absorb and disperse the impact and vibration from the road, reduce the impact of these adverse factors on the cab, and ensure the comfort of the driver and passengers. In addition, the rear suspension lower support can also provide necessary support and protection in an emergency, enhancing the safety of the vehicle. Therefore, the importance of the rear suspension lower support cannot be ignored. It is directly related to the stability, comfort and safety of the commercial vehicle cab, and is an indispensable part of the commercial vehicle suspension system.

[0003] In existing commercial vehicles, the cab is closely connected to the frame through supports to ensure stability and passenger comfort. At the same time, the frame is also connected to the intake system and exhaust system through different supports to ensure smooth engine intake and effective exhaust gas discharge.

[0004] However, although various supports ensure the stable connection of various components of commercial vehicles, they also increase the weight of the vehicle, which is to some extent contrary to the lightweight design goal of the vehicle. In addition, since these supports are installed in similar positions on the frame, the internal space of the frame becomes tight, which limits the subsequent improvement and upgrade space and is not conducive to the continuous optimization and development of the vehicle. Summary of the invention

[0005] In view of the problem that existing supports are of many types and single functions, which will increase vehicle weight and tighten space, the utility model provides an integrated rear suspension lower support for a commercial vehicle cab that can realize multiple connections without increasing vehicle weight and tightening space.

[0006] In order to solve the above problems, the technical solution adopted by the utility model is an integrated rear suspension lower support for a commercial vehicle cab, including a support body, a fixing hole 1 is provided on the support body, the fixing hole 1 can be connected to the frame, a connecting hole 1 is provided on the support body, the connecting hole 1 can be connected to the cab suspension, and the support body is also provided with a connecting hole 2, which can be connected to the intake system or the exhaust system. Through the fixing hole 1, the support body can be firmly fixed on the frame. At the same time, by using the connecting hole 1, the support body can be closely connected with the cab suspension, and the connecting hole 2 can connect the support body to the intake system or the exhaust system. Therefore, the integrated rear suspension lower support integrates multiple connection functions, which not only significantly reduces the weight of the whole vehicle and reduces the material cost, but also optimizes the space layout inside the frame, providing convenience for the continuous optimization and development of the vehicle.

[0007] Preferably, arms are fixed to both left and right sides of the support body, and the two arms are symmetrical about the support body. The two arms significantly enhance the stability of the support body and improve the bearing capacity and durability of the overall structure.

[0008] Preferably, two fixing holes are provided on both arms, and the two fixing holes are symmetrical about the support body. The two fixing holes can ensure that the support body is firmly and stably fixed on the frame, thereby improving the structural stability and safety of the whole vehicle.

[0009] Preferably, the bottom surface of the support arm is perpendicular to the side surface of the support body. The bottom surface of the support arm is perpendicular to the side surface of the support body, which effectively disperses the load acting on the support body and significantly improves the overall stability and bearing capacity of the support body.

[0010] Preferably, the connection holes 1 include three, the three connection holes 1 are arranged in a triangle, and the center lines of the three connection holes 1 are perpendicular to the side of the support body. The stability of the triangle ensures that the connection between the cab suspension and the support body is stable and reliable.

[0011] Preferably, the connection holes 2 include three, the three connection holes 2 are arranged in a triangle, and the center lines of the three connection holes 2 are perpendicular to the side of the support body. The stability of the triangle ensures that the connection between the intake system or the exhaust system and the support body is stable and reliable.

[0012] Preferably, the depth of the second connection hole is greater than the depth of the first connection hole. In order to meet different requirements in actual use, the depth of the second connection hole is designed to be greater than the first connection hole to ensure stronger connection stability and adaptability.

[0013] Preferably, the distance from the right end of the second connection hole to the right side of the support body is 15 mm longer than the distance from the left end of the second connection hole to the left side of the support body. The distance from the right end of the second connection hole to the right side of the support body is 15 mm longer than the distance from the left end to the left side. This design meets the connection requirements of the intake system or the exhaust system and improves the convenience and accuracy of the connection.

[0014] Preferably, the support body is provided with reinforcing ribs, which significantly enhance the connection strength of the structure and provide a more stable and reliable support for the overall structure.

[0015] Preferably, a concave arc is provided on the support body, and the concave arc is located between the second connection hole and the bottom surface of the support body. The concave arc shape is adopted in the design of the support body, which not only ensures the strength of the support body, but also effectively reduces the weight through the arch structure, achieving a balance between lightweight and structural strength.

[0016] It can be seen from the above technical solutions that the advantages of the utility model are: through fixing hole one, the support body can be firmly fixed on the frame to ensure the stability of the overall structure. At the same time, by using connecting hole one, the support body is closely connected to the cab suspension, ensuring the stability of the cab and the comfort of the passengers. Furthermore, connecting hole two connects the support body to the intake system or the exhaust system to achieve smooth operation of the power system. In summary, the integrated rear suspension lower support integrates multiple connection functions, which not only significantly reduces the weight of the vehicle and reduces material costs, but also optimizes the space layout inside the frame, providing convenience for the continuous optimization and development of the vehicle.

[0027] like Figure 1-4 As shown, in this specific embodiment, the support body 1 specifically adopts the following structure: a fixing hole 11 is provided at the lower end of the support body 1, the center line of the fixing hole 11 is perpendicular to the bottom surface of the support body 1, and the size of the fixing hole 11 is adapted to the mounting hole on the frame 5. The bottom surfaces of the two support arms 2 are in the same horizontal plane as the bottom surface of the support body 1, and the bottom surfaces of the two support arms 2 are perpendicular to the side surface of the support body 1. A fixing hole 21 is provided on each of the two support arms 2, the two fixing holes 21 are symmetrical about the support body 1, and the size of the fixing hole 21 is adapted to the mounting hole on the frame 5. The support body 1 can be fixed to the frame 5 by passing bolts through the fixing hole 11 and the fixing hole 21.

[0028] The support body 1 is provided with a connection hole 12, which is located at the upper end of the support body 1. There are three connection holes 12 in total, which are arranged in a triangle, and the center lines of the three connection holes 12 are perpendicular to the side of the support body 1, that is, when viewed from the side of the support body 1, the centers of the three connection holes 12 can form a triangle.
