Currently, the commonly used shock-absorbing components in auxiliary support systems are leaf spring crossbeams, circular torsion bar crossbeams, or rubber damping pads. These components have fixed stiffness and limited damping effectiveness. Furthermore, the fixed supports that match the crossbeams are affected by the inclination angle of the transmission, resulting in a wide variety of fixed supports and poor versatility, hindering production management.

[0016] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0018] like Figure 1-3, a gearbox auxiliary support device according to a preferred embodiment of the present invention comprises a crossbeam 1, a fixed support 2 and a shock-absorbing sleeve 3. Fixed supports 2 are respectively provided at both ends of the crossbeam 1. The fixed support 2 is provided with a mounting chamber 21 for cooperating with the shock-absorbing sleeve 3. The shock-absorbing sleeve 3 is provided with a mounting opening 31 for cooperating with the end plate of the crossbeam 1. The interior of the shock-absorbing sleeve 3 is a hollow structure, and the interior of the shock-absorbing sleeve 3 is filled with a non-Newtonian fluid 32.
[0019] The installation process of this embodiment is as follows: first, install the two fixed supports 2 on the vehicle frame, then install the shock-absorbing sleeve 3 in the installation chamber 21 of the fixed support 2, then insert the two ends of the crossbeam 1 into the installation openings 31 of the shock-absorbing sleeve 3 respectively, so that the shock-absorbing sleeve 3 wraps the end of the crossbeam 1, and finally connect the crossbeam 1 to the gearbox 4 to realize the installation of the auxiliary support device, which is easy to install.
[0020] The working principle of this embodiment is: when the vehicle encounters a bumpy road surface causing the gearbox 4 to bounce, the shock-absorbing sleeve 3 is subjected to the vibration impact transmitted from the gearbox 4 to the crossbeam 1, and the non-Newtonian fluid 32 in the shock-absorbing sleeve 3 thickens and hardens, thereby achieving shock absorption and limiting effects, and the shock absorption effect changes with the vibration intensity, effectively reducing the vibration of the gearbox 4, and the crossbeam 1 itself also has a shock absorption effect, that is, the shock-absorbing sleeve 3 and the crossbeam 1 are combined to achieve a double shock absorption effect to make the shock absorption effect of the gearbox 4 better; the end of the crossbeam 1 cooperates with the installation port 31 of the shock-absorbing sleeve 3, that is, the shock-absorbing sleeve 3 wraps the end of the crossbeam 1, thereby achieving the purpose of slowing down the vibration of the crossbeam 1 in all directions. Compared with the common steel plate crossbeam 1 structure auxiliary support which only has the shock absorption effect of up and down jumping, the present invention can more effectively reduce the vibration of the gearbox 4.
[0021] For example, the shock-absorbing sleeve 3 is made of a flexible material. When the gearbox 4 bounces, the vibration of the gearbox 4 is transmitted to the crossbeam 1, and the crossbeam 1 acts on the shock-absorbing sleeve 3. Since the shock-absorbing sleeve 3 is made of a flexible material, the shock-absorbing sleeve 3 will deform when subjected to force, thereby helping to transmit the force applied to the installation port 31 to the non-Newtonian fluid 32 in the shock-absorbing sleeve 3, thereby giving full play to the shock-absorbing performance of the non-Newtonian fluid 32.
[0022] Exemplarily, the shock-absorbing sleeve 3 is made of elastic material. When the beam 1 rotates, the mounting opening 31 is deformed and, under the action of elastic force, the mounting opening 31 keeps wrapping the end of the beam 1. When the beam 1 is connected to the gearbox 4, in order to facilitate the connection between the beam 1 and the gearbox 4 and to ensure that the beam 1 can be evenly stressed when the gearbox 4 jumps, the position of the beam 1 needs to be adapted to the inclination angle of the gearbox 4 so that the bottom surface of the beam 1 and the top surface of the gearbox 4 are fit and connected. In this embodiment, since the shock-absorbing sleeve 3 is made of elastic material, only the position of the beam 1 needs to be rotated, and the mounting opening 31 will adaptively deform, so that the bottom surface of the beam 1 can be adjusted to fit and connect with the top surface of the gearbox 4, that is, the shock-absorbing sleeve 3 can meet the installation and use requirements of gearboxes 4 with different inclination angles, and has strong applicability. At the same time, it can ensure that the shock-absorbing sleeve 3 wraps the end of the beam 1 to play a shock-absorbing role on all sides of the end of the beam 1.
[0023] For example, the shock-absorbing sleeve 3 is made of rubber or silicone, which has good flexibility and elasticity. At the same time, the shock-absorbing sleeve 3 is made of flexible material, so the contact between the crossbeam 1 and the shock-absorbing sleeve 3 will not generate noise due to rigid collision, which can reduce the vehicle noise.
[0024] For example, the crossbeam 1 includes an integrally formed connecting section 11, a transition section 12 and a mounting section 13. The connecting section 11 and the transition section 12 are respectively provided with two sections. The connecting section 11 is located at both ends of the crossbeam 1, the mounting section 13 is located in the middle of the crossbeam 1, and the transition section 12 is located between the connecting section 11 and the mounting section 13. The connecting section 11 cooperates with the mounting opening 31, and the mounting section 13 is connected to the top of the gearbox 4 by bolts, thereby realizing the connection between the crossbeam 1 and the gearbox 4. The connecting section 11 is arranged in parallel with the mounting section 13, and the mounting section 13 is arranged in parallel with the mounting section 13. 3 is higher than the height of the connecting section 11, that is, in the direction from the connecting section 11 to the mounting section 13, the transition section 12 is inclined upward, so that the mounting section 13 protrudes upward relative to the connecting section 11, thereby forming a space for placing the gearbox 4, and at the same time making the crossbeam 1 as a whole arch bridge-shaped, resistant to stress. In addition, the height of the mounting section 13 can be lower than the height of the connecting section 11, and the transition section 12 can be inclined downward from the connecting section 11 to the mounting section 13, or the heights of the connecting section 11, the mounting section 13 and the transition section 12 can be kept consistent.
[0025] Exemplarily, a fixing plate 22 is provided at one end of the fixing support 2 away from the crossbeam 1 , and the fixing plate 22 is mounted on the vehicle frame by bolts, thereby achieving installation and fixation of the entire auxiliary support device.
[0026] For example, the angle formed by the crossbeam 1 and the horizontal plane is consistent with the inclination angle of the gearbox 4, so that the bottom surface of the crossbeam 1 and the top surface of the gearbox 4 are fitly connected, so that during the bouncing process of the gearbox 4, the bouncing pressure of the gearbox 4 can be evenly distributed on the contact surface between the crossbeam 1 and the gearbox 4. It should be noted that the angle formed by the crossbeam 1 and the horizontal plane is consistent with the inclination angle of the gearbox 4, which is the preferred solution. When the angle formed by the crossbeam 1 and the horizontal plane is inconsistent with the inclination angle of the gearbox 4, the installation of the crossbeam 1 and the gearbox 4 can also be achieved, but it does not have the above-mentioned advantages.
[0027] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
