[0002] The tractor front axle is the important component of tractor, is located tractor front part, mainly comprises front axle, steering knuckle, kingpin etc.

[0003] The tractor front axle produces a large amount of vibration in the process of driving or operation due to uneven road surface, engine operation and other factors, so damping device is needed to buffer and damp, to prevent vibration from causing damage to front axle parts, vehicle body and driver, and the tractor front axle damping device generally absorbs and dissipates vibration through spring, damper and other components, thereby reducing vibration transmission, improving the stability and comfort of tractor.

[0004] But the existing tractor front axle damping device has the following shortcomings:

[0005] In the prior art, the structure of the tractor front axle damping device is often single, considering that the tractor is often operated in complex and harsh environment, the ups and downs of the ground and the bumps and pits are inevitable, and a large amount of vibration with high strength and multiple frequency characteristics will be generated, and such single damping structure has limited ability to deal with such complex vibration, and cannot fully play the damping effect, so that the vibration is difficult to be effectively attenuated, resulting in reduced driving comfort of the driver and operation stability of the tractor.

[0006] Therefore, we propose a tractor front axle damping device to solve the problems in the above background. CONTENT OF THE UTILITY MODEL

[0007] The utility model aims at providing a tractor front axle damping device, two groups of damper assemblies can preliminarily buffer vibration and weaken the impact force of vibration, then four groups of dampers and four groups of first shock absorber springs further inhibit the continuous transmission of vibration, reduce vibration frequency, on the other hand, absorb vibration energy, play the effect of elastic buffering, when facing extreme complex road conditions, the above damping measures are not enough to completely eliminate vibration, two groups of second shock absorber springs further absorb and disperse the remaining vibration energy, to solve the problems in the above background.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: a tractor front axle vibration damping device, comprising a front axle body, two sets of fixing brackets fixedly installed on the outer wall of the front axle body, a vibration damper movably sleeved on the outer wall of each of the two sets of fixing brackets, a connecting seat movably inserted into the inner wall of each of the two sets of vibration dampers, a support plate fixedly connected between the tops of each of the two sets of connecting seats, two first rubber pads fixedly connected to the top of each of the two sets of fixing brackets, a damper fixedly connected to the top of each of the four sets of first rubber pads, and a first damping spring movably sleeved on the outer wall of each of the four sets of dampers.

[0009] Preferably, a second rubber pad is fixedly connected to the top of each of the four sets of dampers, and a mounting plate is fixedly connected between the tops of the four sets of second rubber pads.

[0010] Preferably, a set of second damping springs is fixedly connected to the top of each of the two mounting plates, and the bottom of the two support plates is fixedly connected to the outer wall of the two sets of second damping springs.

[0011] Preferably, the outer walls of both support plates are provided with two sets of first threaded grooves, and the inner walls of the four sets of first threaded grooves are threaded with first fixing bolts.

[0012] Preferably, corrugated protective sleeves are movably fitted between the outer walls of the four sets of the first fixing bolts.

[0013] Preferably, the outer wall of the front axle body is provided with four sets of second threaded grooves.

[0014] Preferably, the inner surface of each of the four sets of second threaded grooves is threaded with a second fixing bolt, and the outer surface of the four sets of second fixing bolts is movably inserted into the interior of the four corrugated protective sleeves.

[0015] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0016] 1. In this utility model, through the interaction of the various components of the device, the two sets of damper components can initially buffer the vibration and weaken the impact force of the vibration. Subsequently, the four sets of dampers and the four sets of first damping springs further suppress the continuous transmission of vibration and reduce the vibration frequency. On the other hand, they absorb vibration energy and play an elastic buffering role. When facing extremely complex road conditions, if the above-mentioned vibration reduction measures are insufficient to completely eliminate the vibration, the two sets of second damping springs further absorb and disperse the remaining vibration energy. In this way, the front axle vibration reduction device realizes multiple vibration reduction functions. When the tractor operates in a complex and harsh environment and generates a large number of vibrations with high intensity and multiple frequencies, this multiple vibration reduction structure can effectively attenuate, absorb and filter the vibration, prevent the vibration from being transmitted without obstruction, and greatly improve the driver's driving comfort and the tractor's operating stability.

In this utility model, through the interaction of the various components of the device, the four corrugated protective sleeves can provide effective protection for the vibration damping components, which can isolate external dust, mud, rainwater and other debris, and resist sharp objects to prevent them from eroding, colliding or damaging the vibration damping components, thereby ensuring the stable performance of the vibration damping components and maintaining structural integrity. In addition, the four corrugated protective sleeves are easy to disassemble, which facilitates the subsequent inspection, maintenance, repair or replacement of parts of the vibration damping components, ensuring that the entire vibration damping system is always in good working condition.

Detailed Implementation

[0023] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] Example 1, as shown in the attached document Figure 1 -Appendix Figure 4As shown, this utility model provides a technical solution: a tractor front axle vibration damping device, including a front axle body 1, two sets of fixing brackets 2 are fixedly installed on the outer wall of the front axle body 1, a damper 3 is movably sleeved on the outer wall of each of the two sets of fixing brackets 2, a connecting seat 4 is movably inserted into the inner wall of each of the two sets of dampers 3, a support plate 5 is fixedly connected between the tops of the two sets of connecting seats 4, two first rubber pads 6 are fixedly connected to the top of each of the two sets of fixing brackets 2, a damper 7 is fixedly connected to the top of each of the four sets of first rubber pads 6, a first damping spring 8 is movably sleeved on the outer wall of each of the four sets of dampers 7, a second rubber pad 9 is fixedly connected to the top of each of the four sets of second rubber pads 7, a mounting plate 10 is fixedly connected between the tops of each of the four sets of second rubber pads 9, a second damping spring 11 is fixedly connected to the top of each of the two mounting plates 10, and the bottom of the two support plates 5 is fixedly connected to the outer wall of the two sets of second damping springs 11.

[0026] The overall effect of Embodiment 1 is as follows: During the use of the front axle body 1, the vibration generated by the wheels during driving is first absorbed and converted by two sets of shock absorbers 3. These two sets of shock absorbers 3 can effectively reduce the intensity of the vibration and perform initial buffering. Subsequently, the vibration is further absorbed by four sets of dampers 7. At the same time, four sets of first damping springs 8 also play a role in further weakening the transmission of vibration and providing additional buffering effect. In addition, the setting of four sets of first rubber pads 6 and four sets of second rubber pads 9 can further enhance the damping effect. Through the elasticity and damping characteristics of rubber materials, vibration is further absorbed and isolated. When the road conditions are bad and the above-mentioned damping measures still cannot completely eliminate the vibration, two sets of second damping springs 11 will further intervene during the transmission of vibration to the frame, providing additional damping support to ensure that the vibration is reduced to the maximum extent. Through this multi-vibration damping design, the vibration generated during tractor operation can be reduced as much as possible, so that even in complex road conditions, high-intensity vibration can be effectively absorbed and isolated, thereby improving the driver's comfort and the stability of operation.

[0027] Example 2, as Figures 2-4 As shown, the outer walls of the two support plates 5 are provided with two sets of first threaded grooves 12, the inner walls of the four sets of first threaded grooves 12 are threaded with first fixing bolts 13, and the outer walls of the four sets of first fixing bolts 13 are movably fitted with corrugated protective sleeves 14. The outer walls of the front axle body 1 are provided with four sets of second threaded grooves 15, the inner walls of the four sets of second threaded grooves 15 are threaded with second fixing bolts 16, and the outer walls of the four sets of second fixing bolts 16 are movably inserted into the four corrugated protective sleeves 14.

[0028] The overall effect of Embodiment 2 is as follows: During use, since tractors often need to operate in harsh or complex and changeable environments, the four corrugated protective sleeves 14 can effectively protect the vibration damping components, ensuring that external dust, mud, rainwater, and other debris or sharp objects will not cause corrosion, collision, or damage to the vibration damping components, ensuring the performance stability and structural integrity of the vibration damping components, thereby maintaining the smooth operation of the tractor, extending the service life of the vibration damping components, and improving the reliability of the equipment. In addition, the corrugated protective sleeves 14 are made of rubber material, which is relatively soft and has certain elasticity. When the vibration damping components move in and out due to vibration, the corrugated protective sleeves 14 can also extend or contract accordingly, thus always tightly wrapping the vibration damping components and continuously exerting protective effects.

[0029] The working principle of the entire device is as follows: During use, the chassis is mounted on top of two support plates 5. When the tractor vibrates due to external forces such as road bumps and impacts during operation, the two sets of shock absorbers 3 first play their role, buffering the vibration and initially reducing its amplitude. Subsequently, four sets of dampers 7 further suppress the continuous transmission of vibration, reducing its frequency and intensity. At the same time, four sets of first damping springs 8 further absorb vibration energy, providing elastic buffering. In addition, four sets of first rubber pads 6 and four sets of second rubber pads 9 can further attenuate vibration through their own elastic deformation, thereby significantly reducing the vibration amplitude transmitted to the chassis and improving driving comfort and stability. Furthermore, when the road conditions are extremely poor and the above-mentioned vibration damping measures cannot completely eliminate the vibration, the two sets of second damping springs 11 further play their role during the transmission of vibration to the chassis. Through their own compression and extension, they absorb and disperse the remaining vibration energy, ensuring that the chassis is not subjected to vibration. The vibration is kept within an acceptable range. Through this multi-stage vibration reduction design, the vibration generated by the tractor's operation can be reduced or eliminated as much as possible. The four corrugated protective sleeves 14 can effectively protect the vibration damping components. The corrugated protective sleeves 14 have certain elasticity characteristics. When the vibration damping components move in and out due to vibration, the corrugated protective sleeves 14 can also extend or contract accordingly, always closely fitting the vibration damping components and preventing external dust, mud, rainwater and other debris from entering, thus protecting the performance of the vibration damping components. When it is necessary to maintain or replace parts of the vibration damping components, simply loosen the four sets of first fixing bolts 13 and the four sets of second fixing bolts 16 to remove the four corrugated protective sleeves 14. After the maintenance operation is completed, the four sets of first fixing bolts 13 can be screwed into the corresponding first thread grooves 12 and the four sets of second fixing bolts 16 can be screwed into the corresponding second thread grooves 15 to re-fix the four corrugated protective sleeves 14, so that they can continue to protect the vibration damping components.

[0030] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
