Description

Technical Field

[0001] This utility model belongs to the field of vehicle manufacturing technology, specifically relating to a left rear power suspension active side bracket applied to a plateau dump truck. Background Technology

[0002] In high-altitude and cold-weather dump trucks, the suspension bracket is the connecting structure between the powertrain and the powertrain suspension. Powertrain excitation is transmitted to the suspension through the bracket, and the suspension attenuates vibration through its vibration isolation and stiffness. In this process, if the suspension bracket can reduce the excitation transmitted from the powertrain, it will play a decisive role in the vibration attenuation of the entire suspension system. In existing technologies, increasing the bracket thickness can usually improve vibration isolation capability. However, if the increase in the thickness of the isolation structure is small, problems such as poor durability and easy cracking will occur. If the increase in the thickness of the isolation structure is large, it will lead to an increase in low-frequency excitation of the powertrain. In addition, increasing the thickness of the isolation structure makes the entire structure very bulky, occupies a lot of space, increases installation difficulty, and makes it difficult to meet the needs of lightweight vehicle development. Secondly, current active side brackets have a single function, with each functional bracket distributed and performing its own function, which affects the structural strength and installation stability of each functional bracket. Utility Model Content

[0003] To address the technical problems existing in the prior art, this utility model provides an active side bracket for the left rear power suspension of a truck. The entire structure has been rationally optimized and simplified.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a truck left rear power suspension active side bracket, including a base, an intermediate frame and a suspension bracket, wherein the base and the suspension bracket are connected through the intermediate frame, and the base, the intermediate frame and the suspension bracket are integrally formed.

[0005] The base is provided with a first base, a second base, and a third base, which form a triangular structure. The first base and the second base are connected by a first arc segment, the second base and the third base are connected by a second arc segment, and the first base and the third base are connected by a third arc segment. The first, second, and third arc segments further reduce the weight of the entire base, and the curved surface design further enhances the design strength.

[0006] The first base has two first base platforms with first connecting through holes. The second base has a second base platform with a second connecting through hole. The third base has a third base platform with a third connecting through hole. Bolts pass through the corresponding first base platform, second base platform and third base platform and are connected to the C-shaped beam of the vehicle body.

[0007] The first base is connected to the suspension bracket via the fourth arc segment, the second base is connected to the suspension bracket via the fifth arc segment, and the third base is connected to the suspension bracket via the sixth arc segment. The fourth, fifth, and sixth arc segments further reduce the weight of the intermediate frame, and the curved surface design further enhances the design strength.

[0008] The suspension bracket is equipped with two fourth bases, and each fourth base has a fourth connecting through hole. Bolts pass through the corresponding fourth connecting through holes and are connected to the gearbox.

[0009] The bottom of the base is provided with a first weight-reducing groove. The first weight-reducing groove conforms to the structural arrangement of the base and the intermediate frame. The first weight-reducing groove is located between the first base, the second base and the third base. The first weight-reducing groove extends into the intermediate frame. The first weight-reducing groove further reduces the weight of the entire support.

[0010] The suspension bracket is provided with a second weight-reducing groove, which is arranged on the fifth arc segment. The second weight-reducing groove has an open structure and avoids the two fourth connecting through holes. Without affecting the structural strength of the suspension bracket, the second weight-reducing groove further reduces the weight of the suspension bracket.

[0011] The outer ends of the first base are rounded, the outer ends of the second base are rounded, and the outer ends of the third base are rounded.

[0012] The first arc segment is a concave arc structure, the second arc segment is a concave arc structure, and the third arc segment is a concave arc structure. The concave arc structure can further reduce the weight of the entire base and reduce the installation space of the base.

[0013] The fourth arc segment is a concave arc structure, the fifth arc segment is a concave arc structure, and the sixth arc segment is a concave arc structure. The concave arc structure can further reduce the weight of the intermediate frame and reduce the installation space of the base.

[0014] Compared with the prior art, the specific advantages of this utility model are as follows: The left rear power suspension active side bracket of this utility model is made of cast steel, which reduces the overall product weight and manufacturing cost, while ensuring the stable operation of the vehicle engine in high-altitude areas; This utility model has multiple curved surface structures arranged according to its structure, which can reduce the overall weight while ensuring the overall structural strength; The overall structure of this utility model is simple, with the first base, second base and third base arranged in a triangle, which has good stability and support performance, and the whole structure is easy to produce and assemble; This utility model is integrally cast, lightweight, low cost, has good economic benefits, and can be widely promoted and applied.
