[0020] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention are described in detail below.

[0021] The following is for reference. Figures 1-2 The present invention describes a steering gear mounting bracket 100 according to an embodiment of the present invention, and also proposes a vehicle.

[0022] Reference Figures 1-3 As shown, the steering gear mounting bracket 100 of this utility model embodiment includes: a main mounting platform 11, a first mounting platform 12, and a second mounting platform 13. The first mounting platform 12 is disposed on the front side of the main mounting platform 11, and the second mounting platform 13 is disposed on the rear side of the main mounting platform 11. The main mounting platform 11 is used to mount the steering gear, and the steering gear mounting bracket 100 is mounted on the front connecting beam through the first mounting platform 12 and the second mounting platform 13. like Figure 1 As shown, the main installation platform 11 includes: a platform body 21, a first load-bearing wall 22, a second load-bearing wall 23, and a side wall 24. The first load-bearing wall 22 is connected between the first installation platform 12 and the platform body 21, the second load-bearing wall 23 is connected between the second installation platform 13 and the platform body 21, and the side wall 24 is connected between the first load-bearing wall 22 and the second load-bearing wall 23 to form a frame structure with internal space.

[0023] First, the mounting holes reserved for the steering gear bracket on the front connecting beam are not on the same plane, and have a large span in the X and Y directions of the vehicle coordinate system. However, the 25 steering gear mounting holes are arranged neatly on the same plane, and the steering gear mounting angle is constant. That is, the problem of the large span of the non-equidistant variable plane mounting holes can be solved by the frame structure of the steering gear bracket, while reserving sufficient movement space for the steering rocker arm and facilitating the installation and removal of the steering gear mounting bolts.

[0024] Specifically, the main mounting platform 11 is provided with a first mounting platform 12 and a second mounting platform 13 at its front and rear ends. The first mounting platform 12 and the second mounting platform 13 can be connected to the mounting holes of the front connecting beam, thereby solving the problem of large span of non-equidistant variable plane mounting holes.

[0025] In addition, the first load-bearing wall 22 and the second load-bearing wall 23 are connected via a side wall 24. The side wall 24 acts as a reinforcing rib in the frame structure, increasing local rigidity to suppress deformation and ensure that the steering gear bracket meets the strength requirements. Thus, the main mounting platform 11, the first mounting platform 12, and the second mounting platform 13 form a frame structure, which can solve the problem that the mounting holes reserved for the steering gear bracket by the front connecting beam have a large span in the X and Y directions under the vehicle coordinate system, while reserving sufficient movement space for the steering rocker arm.

[0026] Among them, such as Figure 3 As shown, the platform body 21 has multiple spaced steering gear mounting holes 25, which are rectangularly distributed on the platform body 21. These holes are used to mount steering gears. The steering gear is the core component of the steering system, typically mounted on the vehicle frame and connected to the steering column (the end of the steering wheel). The driver requires relatively little force to turn the steering wheel, while steering the wheels requires a greater force. The steering gear uses internal gear or screw mechanisms (such as rack and pinion, recirculating ball, worm gear crank pin, etc.) to achieve mechanical speed reduction and amplify the input torque.

[0027] The platform body 21 has multiple rectangular steering gear mounting holes 25, allowing the steering gear to be mounted on the platform body 21 through these holes. Furthermore, the multiple steering gear mounting holes 25 are arranged in a rectangle to accommodate the shape of the steering gear.

[0028] like Figure 1 As shown, a first positioning boss 27 is provided on the side of the steering gear mounting hole 25 opposite to the front connecting beam. The first positioning boss 27 provides positioning and guiding functions; that is, it can serve as a positioning reference during assembly, ensuring accurate alignment of the connected parts. Furthermore, the first positioning boss 27 can cooperate with the mounting hole on the steering gear to achieve a self-positioning function, simplifying the assembly process.

[0029] In addition, the first positioning boss 27 can improve local strength and rigidity. Specifically, the material around the steering gear mounting hole 25 will be subjected to greater stress under the preload of bolts or screws. Setting the first positioning boss 27 can increase the material thickness in this area, thereby improving the local structural strength and rigidity and preventing deformation, cracking or crushing caused by stress concentration.

[0030] Furthermore, the first positioning boss 27 can also improve the force distribution. The first positioning boss 27 can transmit the clamping force of the bolt or screw to the connected parts more evenly, avoiding the force concentration at the edge of the hole.

[0031] In addition, such as Figure 1 and Figure 3 As shown, the platform body 21 is provided with a steering rocker arm through hole 26. The steering rocker arm is connected to the steering gear through the steering rocker arm through hole 26 and swings inside the frame structure. That is to say, the platform body 21 is also provided with a steering rocker arm through hole 26, so that the steering rocker arm can be connected to the steering gear through the steering rocker arm through hole 26. That is, one end of the steering rocker arm is connected to the output shaft of the steering gear, and the other end is connected to the steering transmission mechanism (such as a tie rod) through a ball joint hinge.

[0032] The steering rocker arm through hole 26 is sandwiched between the two steering gear mounting holes 25.

[0033] Furthermore, the driver's steering operation process is as follows: The driver turns the steering wheel, the steering column transmits the rotation to the steering gear, the internal mechanism of the steering gear decelerates and increases torque, causing the steering rocker arm to swing left and right, the steering rocker arm pulls the tie rod, the tie rod pushes the steering knuckle arm, and causes the steering wheel to turn.

[0034] The first mounting platform 12 is provided with a plurality of first mounting holes 31, and the second mounting platform 13 is provided with a plurality of second mounting holes 32. Both the first mounting holes 31 and the second mounting holes 32 are used for fixed connection with the front connecting beam.

[0035] Reference Figure 3 As shown, multiple first mounting holes 31 are disposed at the edge of the first mounting platform 12. That is to say, the shape and outline of the first mounting platform 12 are designed according to the outer contour formed by the combination of the multiple first mounting holes 31, and the outline of the first mounting platform 12 is close to the arc of the first mounting holes 31. This allows the multiple first mounting holes 31 to be disposed at the edge of the first mounting platform 12, thereby reducing the area of ​​the first mounting platform 12 and thus achieving a weight reduction effect, preventing the steering gear bracket from being too heavy.

[0036] Similarly, refer to Figure 3As shown, multiple second mounting holes 32 are disposed at the edge of the second mounting platform 13. That is to say, the shape and outline of the second mounting platform 13 are designed according to the outer contour formed by the combination of the multiple second mounting holes 32, and the outline of the second mounting platform 13 is close to the arc of the second mounting holes 32. This allows the multiple second mounting holes 32 to be disposed at the edge of the second mounting platform 13, thereby reducing the area of ​​the second mounting platform 13 and thus achieving a weight reduction effect, preventing the steering gear bracket from being too heavy.

[0037] like Figure 1 As shown, both the first mounting hole 31 and the second mounting hole 32 have a second positioning boss 33 on the side opposite to the front connecting beam. The second positioning boss 33 provides positioning and guiding functions; that is, it can serve as a positioning reference during assembly, ensuring accurate alignment of the connected parts. Furthermore, the second positioning boss 33 can cooperate with the mounting holes on the front connecting beam to achieve a self-positioning function, simplifying the assembly process.

[0038] In addition, the second positioning boss 33 can improve local strength and rigidity. Specifically, the material around the first mounting hole 31 and the second mounting hole 32 will bear a large stress under the action of bolt or screw preload. The second positioning boss 33 can increase the material thickness in this area, thereby improving the local structural strength and rigidity and preventing deformation, cracking or crushing caused by stress concentration.

[0039] Furthermore, the second positioning boss 33 can also improve the force distribution. The second positioning boss 33 can transmit the clamping force of the bolt or screw to the connected parts more evenly, avoiding the force concentration at the edge of the hole.

[0040] An angle is formed between the side of the first mounting platform 12 away from the main mounting platform 11 and the edge of the main mounting platform 11. This angle facilitates the fixed connection between the first mounting platform 12 and the front connecting beam.

[0041] Similarly, an angle is formed between the side of the second mounting platform 13 away from the main mounting platform 11 and the edge of the main mounting platform 11. This angle facilitates the fixed connection between the second mounting platform 13 and the front connecting beam.

[0042] Furthermore, referring to Figure 1 As shown, the height of the first load-bearing wall 22 is lower than that of the second load-bearing wall 23. This is due to the structure of the front beam, where the front end of the front beam is lower than the rear end.

[0043] Furthermore, the side wall 24 is lower than the first load-bearing wall 22 and the second load-bearing wall 23. Setting the side wall 24 lower than the first load-bearing wall 22 and the second load-bearing wall 23 can, on the one hand, provide room for the steering rocker arm to move, thereby avoiding interference with the movement of the steering rocker arm by the side wall 24, and on the other hand, it can reduce weight and prevent the steering gear bracket from being too heavy.

[0044] The height difference between the side wall 24 and the first load-bearing wall 22 can be determined by the relative positions of the first installation platform 12 and the second installation platform 13 with the main installation platform 11.

[0045] According to a second aspect of the present invention, a vehicle includes: a frame longitudinal beam, a front connecting beam, and a steering gear bracket. The front connecting beam is fixed on the frame longitudinal beam, the steering gear bracket is fixed on the front connecting beam, and the steering gear and steering rocker arm are fixed on the steering gear bracket.
