Description

Technical Field

[0001] This utility model relates to the field of guide arm technology, specifically a novel truck guide arm. Background Technology

[0002] In the field of truck design and manufacturing, the guide arm is an important transmission component between the axle and the chassis during steering. It is often used at the front end of the air suspension to form a laterally symmetrical stabilizer bar mounting part, and plays a key guiding role.

[0003] However, due to their unique structural characteristics, some existing Z-shaped guide arms often exhibit uneven stress distribution when subjected to complex loads generated by vehicle movement during use. In particular, stress concentration is prone to occur at the corners of the Z-shape. This stress concentration accelerates the fatigue damage process of the guide arm material, shortens its service life, and may even cause cracks or fractures in these critical parts under long-term high stress, posing a serious threat to vehicle driving safety. Utility Model Content

[0004] The purpose of this invention is to provide a novel truck guide arm to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a novel truck guide arm, comprising a guide arm body, and further comprising: A support pad is embedded in the inner wall of the guide arm body. The surface of the support pad is provided with a support block. The support block is provided with a fixing mechanism around its perimeter. Stress relief holes are formed on the surface of the guide arm body to disperse stress. A connecting block is fixedly connected to the bottom of the guide arm body, and a connecting frame is fixedly connected to one side of the connecting block.

[0006] Preferably, the fixing mechanism includes connecting ears fixedly connected to the periphery of the support block, the inner wall of the connecting ears is embedded with a buffer pad, and the inner wall of the connecting ears is threaded with a bolt.

[0007] Preferably, the number of cushioning pads is six, and the material is rubber.

[0008] Preferably, the cross-sectional shape of the support block is a triangular structure design, and the shape of the support pad matches that of the support block.

[0009] Preferably, the number of connecting brackets is three, and the cross-sectional shape is an X-shaped structure design.

[0010] Preferably, the number of support pads is two, and they are evenly distributed at the corners of the guide arm body, and they are made of rubber.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention, through the design of support pads and support blocks, provides excellent auxiliary support for the corners of the guide arm body. The support pads possess elasticity and damping characteristics, allowing them to disperse some stress through deformation when the guide arm body bears a load. The support blocks enhance the structural stability at the corners of the guide arm body, working in conjunction with the support pads to firmly support the corners and provide a reliable point of force for the guide arm body. This effectively reduces the risk of cracks and fractures in the guide arm body caused by stress concentration. Furthermore, the stress relief holes, connecting blocks, and connecting frames further optimize the stress distribution of the guide arm body, reducing excessive stress concentration in localized areas and effectively improving the overall load-bearing capacity of the guide arm body. This solves the problems of insufficient load-bearing capacity and stress concentration in existing guide arms. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-5As shown, a novel truck guide arm includes a guide arm body 1, which has a Z-shaped structure design. The guide arm body 1 works in conjunction with other components of the truck, such as the axle and frame, and has the functions of guiding the movement of the axle and absorbing road vibration and impact.

[0016] The inner wall of the guide arm body 1 is embedded with a support pad 2, and a support block 3 is provided on the surface of the support pad 2. There are two support pads 2, which are evenly distributed at the corners of the guide arm body 1 and are made of rubber. The cross-sectional shape of the support block 3 is a triangular structure design, and the shape of the support pad 2 matches that of the support block 3.

[0017] The cooperation between the support pad 2 and the support block 3 provides good auxiliary support for the corner of the guide arm body 1 and provides a reliable force point for the guide arm body 1. This effectively reduces the risk of cracks and breakage of the guide arm body 1 due to stress concentration and improves the stability of the guide arm body 1 during use.

[0018] The support block 3 is provided with fixing mechanisms 4 on all four sides. The fixing mechanisms 4 can fix the support block 3 to the surface of the guide arm body 1, so that the support block 3 can be stably combined with the guide arm body 1 and give full play to its supporting role at the corner of the guide arm body 1.

[0019] The fixing mechanism 4 includes connecting ears 41 fixedly connected to the support block 3 around the perimeter. The inner wall of the connecting ears 41 is embedded with buffer pads 42. There are six buffer pads 42, and they are made of rubber. The inner wall of the connecting ears 41 is threaded with bolts 43. The surface of the bolts 43 is threadedly connected to the buffer pads 42 and the inner wall of the guide arm body 1. The bolts 43 and the buffer pads 42 are used together.

[0020] With the special material design of the buffer pad 42, the vibration energy between the buffer pad 42 and the bolt 43 can be effectively absorbed and dispersed, making the force on the connection part more uniform, reducing the potential for failure caused by loosening and wear, and providing a strong guarantee for the safe and stable operation of the vehicle.

[0021] The surface of the guide arm body 1 is provided with stress relief holes 5. There are several stress relief holes 5, which are evenly distributed on the surface of the guide arm body 1. By setting several stress relief holes 5, the stress concentrated at a certain point can be dispersed to a wider surrounding area, thereby reducing the local stress peak. This reduces the possibility of the guide arm body 1 undergoing plastic deformation or fatigue cracking prematurely due to excessive stress, and effectively improves the load-bearing capacity and anti-destruction performance of the guide arm body 1.

[0022] Two connecting blocks 6 are fixedly connected to the bottom of the guide arm body 1 and are symmetrical with the center line of the guide arm body 1. Three connecting frames 7 are fixedly connected to one side of the connecting blocks 6 and have an X-shaped cross-sectional design.

[0023] The cooperation between the connecting block 6 and the connecting frame 7 can further enhance the structural stability and strength of the guide arm body 1, improve the load-bearing capacity of the guide arm body 1 under complex working conditions, enable it to cope with various challenges more easily, improve its anti-destruction performance, and reduce the risk of deformation or damage to the guide arm body 1 caused by external impact, vibration and other factors.

[0024] It is worth noting that the technical features such as the guide arm body 1 proposed in this technical solution should be regarded as prior art. The specific structure, working principle, and possible control methods and spatial arrangement of these technical features can be selected using conventional methods in this field. This technical solution will not elaborate further.

[0025] Working principle: First, by setting stress relief holes 5, connecting blocks 6 and connecting frames 7, the stress of the guide arm body 1 can be effectively dispersed, so that the stress can be evenly distributed, reducing local stress peaks, improving the load-bearing and anti-damage performance of the guide arm body 1, and reducing the occurrence of bending deformation of the guide arm body 1.

[0026] With the cooperation of support pad 2 and support block 3, the corner of the guide arm body 1 can play a good auxiliary support role, effectively reducing the risk of cracks and breakage of the guide arm body 1 due to stress concentration. When the support pad 2 needs to be replaced after a long period of use, the operator can use an Allen wrench to remove the bolt 43 from the inner cavity of the guide arm body 1 and the connecting ear 41. At this time, the support block 3 and support pad 2 can be removed to facilitate the operator to install the new support pad 2 into the inner cavity of the guide arm body 1. Then, the bolt 43 is used to fix the support block 3 to the surface of the guide arm body 1, so that the support block 3 can be stably used with the support pad 2.
