Description

Technical Field

[0001] This utility model relates to the field of shock absorber technology, specifically to a rear suspension shock absorber embedded in the upper side of the longitudinal beam of the cab. Background Technology

[0002] In the design and manufacture of modern vehicles, the rear suspension shock absorber of the cab plays a crucial role in improving ride comfort and ensuring vehicle stability.

[0003] Currently, the most common installation method for rear suspension shock absorbers in vehicle cabs is external mounting, which means installing the shock absorber outside the cab. Although this method is relatively convenient for installation and maintenance, the shock absorber is exposed to the outside of the vehicle and is easily affected by external environmental factors, such as sand and gravel impacts, rainwater erosion, and dust accumulation, which can lead to damage to the shock absorber's seals and wear on the piston rod surface, thereby affecting the shock absorber's performance and service life. At the same time, externally mounted shock absorbers also increase the vehicle's air resistance, affecting the vehicle's fuel economy.

[0004] As the vehicle industry continues to demand higher levels of comfort, space utilization, and shock absorber reliability in cabs, the existing cab rear suspension shock absorber installation methods are no longer sufficient to meet market needs. There is an urgent need to develop a new cab rear suspension shock absorber structure and its installation method to solve these problems. Utility Model Content

[0005] To address the problems mentioned in the background art, the purpose of this utility model is to provide a rear suspension shock absorber embedded on the upper side of the cab longitudinal beam, which has the advantage of good performance.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a rear suspension shock absorber embedded on the upper side of a cab longitudinal beam, comprising a longitudinal beam body, a mounting bracket provided on the surface of the longitudinal beam body, a first bolt provided on the surface of the mounting bracket, the number of first bolts being several, the first bolts being threadedly connected to the longitudinal beam body, a mounting block fixedly connected to the front of the mounting bracket, a mounting groove provided at the bottom of the mounting block, a reinforcing tube provided inside the mounting groove, a supporting round rod fixedly connected inside the reinforcing tube, a fixing block fixedly connected to the surface of the reinforcing tube, the fixing block fitting against the mounting block, the number of fixing blocks being several, the fixing blocks being evenly distributed in a ring on the surface of the reinforcing tube, a second bolt provided at the bottom of the fixing block, the second bolt being threadedly connected to the mounting block, and a shock absorber body hinged to the bottom of the supporting round rod.

[0007] As a preferred embodiment of this invention, a rubber ring is fixedly connected to the inner wall of the mounting groove, and the rubber ring is in contact with the reinforcing tube.

[0008] As a preferred embodiment of this invention, the rubber ring is internally fixedly connected with reinforcing ribs, and the number of reinforcing ribs is several, which are evenly distributed in a ring shape inside the rubber ring.

[0009] As a preferred embodiment of this utility model, the bottom of the reinforcing tube is provided with a triangular opening, and the number of the triangular openings is several. The triangular openings are evenly distributed in a ring at the bottom of the reinforcing tube, and a reinforcing strip is fixedly connected inside the triangular opening.

[0010] As a preferred embodiment of this invention, the surface of the shock absorber body is fitted with a telescopic rubber sleeve.

[0011] As a preferred embodiment of this invention, both the first bolt and the second bolt are coated with anti-rust paint.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model employs a mounting bracket on the surface of the longitudinal beam body, with multiple first bolts threadedly connected to the longitudinal beam body, achieving stable installation of the shock absorber. The mounting block on the front of the mounting bracket has a reinforcing tube embedded in its bottom mounting groove. The supporting round rod inside the reinforcing tube is hinged to the shock absorber body, forming a stable support structure. Simultaneously, multiple fixing blocks are evenly distributed in a ring on the surface of the reinforcing tube and fixed to the mounting blocks with second bolts, making the connection between the reinforcing tube and the mounting block more secure. This effectively disperses the stress generated during shock absorption, improving the stability and reliability of the entire shock absorption system. This device has the advantage of excellent performance.

[0014] 2. This utility model, by incorporating a rubber ring on the inner wall of the mounting groove and fitting it against the reinforcing tube, provides excellent cushioning and sealing. When vibrations occur during vehicle operation, the rubber ring absorbs some of the vibration energy, reducing the direct impact of vibrations on the reinforcing tube and mounting block, thereby lowering the risk of wear and damage to components. Simultaneously, the sealing performance of the rubber ring prevents dust, rainwater, and other impurities from entering the mounting groove, avoiding corrosion of the reinforcing tube and support rod, further extending the service life of the shock absorber. Furthermore, the elastic properties of the rubber ring can compensate for minute gaps between the reinforcing tube and the mounting groove, ensuring the stability of the reinforcing tube within the mounting groove and improving the overall performance of the shock absorption system.

[0020] 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.

[0021] like Figures 1 to 4 As shown, a rear suspension shock absorber embedded on the upper side of a cab longitudinal beam includes a longitudinal beam body 1. A mounting bracket 2 is provided on the surface of the longitudinal beam body 1. A first bolt 3 is provided on the surface of the mounting bracket 2. There are several first bolts 3. The first bolts 3 are threadedly connected to the longitudinal beam body 1. A mounting block 4 is fixedly connected to the front of the mounting bracket 2. A mounting groove is provided at the bottom of the mounting block 4. A reinforcing tube 5 is provided inside the mounting groove. A supporting round rod 6 is fixedly connected inside the reinforcing tube 5. A fixing block 8 is fixedly connected to the surface of the reinforcing tube 5. The fixing block 8 fits against the mounting block 4. There are several fixing blocks 8. The fixing blocks 8 are evenly distributed in a ring on the surface of the reinforcing tube 5. A second bolt 9 is provided at the bottom of the fixing block 8. The second bolt 9 is threadedly connected to the mounting block 4. A shock absorber body 7 is hinged to the bottom of the supporting round rod 6.

[0022] refer to Figure 4 A rubber ring 10 is fixedly connected to the inner wall of the mounting groove, and the rubber ring 10 is attached to the reinforcing tube 5.

[0023] As a technical optimization of this utility model, by setting a rubber ring 10 on the inner wall of the mounting groove and fitting it to the reinforcing tube 5, a good buffering and sealing effect can be achieved. When vibration occurs during vehicle operation, the rubber ring 10 can absorb some of the vibration energy, reducing the direct impact of vibration on the reinforcing tube 5 and the mounting block 4, thereby reducing the risk of wear and damage to the components. At the same time, the sealing performance of the rubber ring 10 can prevent dust, rainwater and other impurities from entering the mounting groove, avoiding corrosion of the reinforcing tube 5 and the support rod 6, and further extending the service life of the shock absorber. In addition, the elastic properties of the rubber ring 10 can also compensate for the small gap between the reinforcing tube 5 and the mounting groove, ensuring the stability of the reinforcing tube 5 in the mounting groove and improving the overall performance of the shock absorption system.

[0024] refer to Figure 4 The rubber ring 10 is fixedly connected with a reinforcing rib 11. There are several reinforcing ribs 11, which are evenly distributed in a ring inside the rubber ring 10.

[0025] As a technical optimization of this utility model, by setting multiple uniformly distributed annular reinforcing ribs 11 inside the rubber ring 10, the structural strength and deformation resistance of the rubber ring 10 are significantly enhanced. The reinforcing ribs 11 effectively limit excessive deformation of the rubber ring 10 under stress, maintaining good elasticity and sealing performance during long-term use. When the shock absorber is subjected to a large impact force, the reinforcing ribs 11 can disperse stress, preventing the rubber ring 10 from cracking or being damaged due to excessive local stress, thus ensuring the durability of the buffering and sealing effect of the rubber ring 10. Simultaneously, the addition of reinforcing ribs 11 also improves the rubber ring 10's resistance to temperature changes and chemical corrosion, adapting to harsher working environments and further enhancing the reliability and stability of the entire shock absorption system.

[0026] refer to Figure 4 The bottom of the reinforcing tube 5 is provided with a triangular opening 12. There are several triangular openings 12, which are evenly distributed in a ring at the bottom of the reinforcing tube 5. A reinforcing strip 13 is fixedly connected inside the triangular opening 12.

[0027] As a technical optimization of this utility model, multiple uniformly distributed annular triangular openings 12 are made at the bottom of the reinforcing tube 5, and reinforcing strips 13 are fixedly connected inside the openings. This structural design reduces the weight of the reinforcing tube 5 while improving its structural strength and rigidity. The triangular openings 12 form a truss-like structure, which can effectively disperse and transfer stress, making the reinforcing tube 5 less prone to deformation when subjected to complex loads during shock absorption. The presence of the reinforcing strips 13 further enhances the structural strength at the triangular openings 12, preventing cracking at the edges of the openings due to stress concentration. In addition, this lightweight design also helps reduce the weight of the entire shock absorption system, reduce vehicle energy consumption, and improve fuel economy. At the same time, the design of the triangular openings 12 also provides convenience for the installation and maintenance of the shock absorber, making it easier for operators to perform operations.

[0028] refer to Figure 2 The surface of the shock absorber body 7 is fitted with a telescopic rubber sleeve 14.

[0029] As a technical optimization of this utility model, by covering the surface of the shock absorber body 7 with a telescopic rubber sleeve 14, the shock absorber body 7 can be effectively protected. The telescopic rubber sleeve 14 can prevent sand, dust, and other impurities from directly contacting the piston rod and seals of the shock absorber, reducing the risk of wear and corrosion and extending the service life of the shock absorber. At the same time, the telescopic rubber sleeve 14 has good elasticity and telescopic performance, and will not affect the normal telescopic movement of the shock absorber body 7, and can freely expand and contract with the working state of the shock absorber. During vehicle operation, the telescopic rubber sleeve 14 can also absorb some vibration energy, playing an auxiliary role in shock absorption and improving ride comfort. In addition, the design of the telescopic rubber sleeve 14 can also prevent external moisture and chemicals from corroding the shock absorber, further enhancing the reliability and stability of the shock absorber.

[0030] refer to Figure 1 The surfaces of the first bolt 3 and the second bolt 9 are both coated with anti-rust paint.

[0031] As a technical optimization of this utility model, the corrosion resistance of the bolts is effectively improved by spraying anti-rust paint onto the surfaces of the first bolt 3 and the second bolt 9. During vehicle operation, bolts are easily corroded by rainwater, moisture, and various chemicals, leading to rust and corrosion, which affects the bolt's tightening effect and service life. The anti-rust paint coating forms a protective film, isolating the bolts from contact with the external environment and preventing rust and corrosion. This not only ensures the bolt's tightening force and the connection stability between the mounting bracket 2, mounting block 4, and reinforcing tube 5, but also reduces maintenance and replacement costs due to bolt damage. Furthermore, the anti-rust paint coating also improves the bolt's aesthetics, making the entire shock absorption system cleaner and more durable.

[0032] The working principle and usage process of this utility model are as follows: When the vehicle is in use, uneven road surfaces will cause the wheels to vibrate, and these vibrations will be transmitted to the cab through the suspension system. At this time, the shock absorber body 7 will play a role, converting this kinetic energy into heat energy and dissipating it, thereby reducing the vibration experienced by the cab and improving the comfort of the driver and passengers.

[0033] In this process, the mounting bracket 2 and mounting block 4 play a crucial supporting role, ensuring the stable operation of the shock absorber. The structure composed of the reinforcing tube 5 and the supporting rod 6 further enhances the rigidity of the entire system, ensuring that it will not easily deform under load. The rubber ring 10 is also indispensable; it not only buffers vibrations but also prevents dust and moisture from entering, protecting the internal structure. In addition, the design of the triangular opening 12 and the reinforcing strip 13 is ingenious, reducing the weight of the reinforcing tube 5 while improving its structural strength, making the entire device more stable and reliable.

[0034] First, securely fasten the mounting bracket 2 to the longitudinal beam body 1 using the first bolt 3, ensuring all bolts are tightened to the specified torque. Next, install the rubber ring 10 into the mounting groove of the mounting block 4, then insert the reinforcing tube 5 into the mounting groove, ensuring the fixing block 8 is fully fitted against the mounting block 4. Then, use the second bolt 9 to secure the fixing block 8 and the mounting block 4 together, again ensuring the bolts are tightened. Finally, hinge the shock absorber body 7 to the support rod 6 to complete the installation of the entire shock absorber.

[0035] The aforementioned longitudinal beam body 1 and shock absorber body 7 are both existing common technologies and are common knowledge to those skilled in the art, and will not be described in detail in this application.
