[0037] The embodiments of the present utility model are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present utility model are described in detail below.

[0038] Reference below Figure 1-Figure 9 The steering gear housing 100 according to the embodiment of the present invention is described. The steering gear housing 100 according to the embodiment of the present invention can be applied to a vehicle frame 1000 , and the vehicle frame 1000 according to the embodiment of the present invention can be applied to a vehicle.

[0039] Combination Figure 2 As shown, the steering gear housing 100 according to the utility model can mainly include: a first connection housing 110, a second connection housing 120 and an input shaft housing 20. Specifically, the steering gear housing 100 in the embodiment of the utility model includes the first connection housing 110, the second connection housing 120 and the input shaft housing 20, which can replace the integrated arrangement of the steering gear housing in the prior art, so that the steering gear housing 100 can be arranged in sections.

[0040] Further, the second connection housing 120 is spaced apart from the first connection housing 110 in the first direction, which can provide a setting space for the input shaft housing 20. The input shaft housing 20 is arranged between the first connection housing 110 and the second connection housing 120, and can be rotated and adjusted relative to the first connection housing 110 and the second connection housing 120. Such arrangement can ensure, on the one hand, that the input shaft housing 20 is stably arranged between the first connection housing 110 and the second connection housing 120, and can ensure the setting reliability of the input shaft housing 20 in the steering gear housing 100, so that not only the structural reliability of the steering gear housing 100 can be ensured, but also the transmission reliability of the torque in the steering gear can be ensured. On the other hand, by rotating and adjusting the input shaft housing 20 between the first connection housing 110 and the second connection housing 120, the input shaft housing 20 can be connected between the first connection housing 110 and the second connection housing 120 at a preset angle, so that the input shaft angle on the steering gear can be adjusted.

[0041] In the prior art, the steering gear housing is generally an integrally designed casting structure. Once the steering input shaft angle is determined, it cannot be adjusted. When the steering gear is matched with different vehicle models, the angle and length of the intermediate shaft and the angle of the steering column need to be adjusted. Due to the vehicle's requirements for steering performance, the torque fluctuation is mainly affected by the phase angle, and its adjustment range is limited, and its adaptability to different vehicle models is poor.

[0042] In the embodiment of the utility model, the position of the input shaft housing 20 between the first connection housing 110 and the second connection housing 120 can be rotated and adjusted, so that on the one hand, the input shaft angle can be adjusted without changing the production mold, which is conducive to reducing production costs. On the other hand, within a certain range, the center point of the steering wheel of different models can be adapted to meet the sitting posture requirements of different models, which can improve the generalization of the steering gear for multiple models. In addition, by adjusting the input shaft angle, the phase angle can be adjusted, and in certain circumstances, the torque fluctuation can be reduced, which is conducive to improving the steering performance.

[0043] Combination Figure 4 and Figure 5 As shown, at least one of the first connection housing 110 and the second connection housing 120 is provided with a first guide portion 11, and the input shaft housing 20 is provided with a second guide portion 21, and the first guide portion 11 and the second guide portion 21 are guided and matched. Specifically, at least one of the first connection housing 110 and the second connection housing 120 can provide a stable and reliable setting position for the first guide portion 11, so that the first guide portion 11 can maintain a stable position with at least one of the first connection housing 110 and the second connection housing 120. The input shaft housing 20 can provide a stable and reliable setting position for the second guide portion 21, so that the second guide portion 21 can rotate with the input shaft housing 20.

[0044] Furthermore, when the input shaft housing 20 is rotatably disposed between the first connecting housing 110 and the second connecting housing 120, the first guide portion 11 and the second guide portion 21 are guided and cooperated, so that not only the first guide portion 11 can guide the rotation of the second guide portion 21, but also the rotation of the input shaft housing 20 between the first connecting housing 110 and the second connecting housing 120 can be guided, which is beneficial to improving the convenience of position adjustment of the input shaft housing 20 between the first connecting housing 110 and the second connecting housing 120, and also the input shaft housing 20 can be stably connected between the first connecting housing 110 and the second connecting housing 120, so that the torque can be stably transmitted between the first guide portion 11 and the second guide portion 21, and thus the torque can be stably transmitted between at least one of the first connecting housing 110 and the second connecting housing 120 and the input shaft housing 20. With such a configuration, the convenience of adjusting the input shaft angle and phase angle of the steering gear can be improved, and the structural reliability of the steering gear can be ensured.

[0045] Combination Figure 6 As shown, a plurality of first guide portions 11 are provided on at least one of the first connection housing 110 and the second connection housing 120, and the input shaft housing 20 rotates relative to the first connection housing 110 and the second connection housing 120 so that one of the plurality of first guide portions 11 corresponds to the second guide portion 21. Specifically, when the input shaft housing 20 is rotated, the second guide portion 21 can rotate synchronously. A plurality of first guide portions 11 are provided on at least one of the first connection housing 110 and the second connection housing 120, and the input shaft housing 20 rotates relative to the first connection housing 110 and the second connection housing 120, which can drive the second guide portion 21 to rotate between the plurality of first guide portions 11. When adjusting the input shaft angle to adapt to different vehicle models, the second guide portion 21 can be selected to correspond to one of the plurality of first guide portions 11, and the guides can be matched to connect the input shaft housing 20 between the first connection housing 110 and the second connection housing 120 at a preset angle, thereby realizing the assembly and adjustment of the steering gear housing 100.

[0046] Figure 7-Figure 8 It is a schematic diagram of the position of the input shaft housing 20 between the first connecting housing 110 and the second connecting housing 120 when the second guide portion 21 corresponds to one of the plurality of first guide portions 11 .

[0047] Combination Figure 4 and Figure 5As shown, one of the first guide portion 11 and the second guide portion 21 is a guide groove, and the other is a guide protrusion, and the guide protrusion cooperates with the guide groove. Specifically, the guiding cooperation of the first guide portion 11 and the second guide portion 21 is actually the guiding cooperation of the guide groove and the guide protrusion. The guide groove and the guide protrusion have a simple structure and reliable guidance, which can not only simplify the production operation of the steering gear housing 100, but also help to improve the production convenience of the steering gear housing 100, and can also ensure the guiding reliability of the first guide portion 11 and the second guide portion 21, thereby improving the adjustment convenience and structural reliability of the steering gear housing 100, and can facilitate the adjustment of the input shaft angle when the steering gear is adapted to different vehicle models, and can ensure that the torque is transmitted reliably in the steering gear with different input shaft angles.

[0048] Combination Figure 3-Figure 5 As shown, the first connecting shell 110 and the second connecting shell 120 are both provided with a first guide portion 11, and the second guide portions 21 are respectively provided on both sides of the input shaft shell 20. The second guide portions 21 on both sides of the input shaft shell 20 are respectively guided and matched with the first guide portions 11 on the first connecting shell 110 and the second connecting shell 120. In this way, when the input shaft shell 20 is arranged between the first connecting shell 110 and the second connecting shell 120, both sides of the input shaft shell 20 can be guided and matched with the first connecting shell 110 and the second connecting shell 120.

[0049] With such a configuration, on the one hand, the forces on both sides of the input shaft housing 20 can be evenly distributed, thereby improving the convenience and reliability of position adjustment of the input shaft housing 20 between the first connecting housing 110 and the second connecting housing 120; on the other hand, the torque on the input shaft housing 20 can be simultaneously transmitted to the first connecting housing 110 and the second connecting housing 120 through the guiding cooperation of the first guide portion 11 and the second guide portion 21, so that the torque on the steering wheel can be transmitted to both sides of the first direction of the vehicle through the steering gear, so that people in the vehicle cockpit can achieve stable steering of the vehicle through the steering wheel.

[0050] Combination Figure 3-Figure 5As shown, at least one of the first connecting housing 110 and the second connecting housing 120 has a limiting hole 12 inwardly opened on a side close to the input shaft housing 20 , and a limiting column 22 is provided on the input shaft housing 20 , which extends into the limiting hole 12 and cooperates with the limiting hole 12 in a limiting manner. Specifically, a limiting hole 12 is opened on at least one of the first connecting shell 110 and the second connecting shell 120, and a limiting column 22 protruding outward is set on the input shaft shell 20. When the input shaft shell 20 is set between the first connecting shell 110 and the second connecting shell 120, the limiting column 22 can be extended into the limiting hole 12. This can not only shorten the distance between the input shaft shell 20 and at least one of the first connecting shell 110 and the second connecting shell 120, but also shorten the transmission path of the torque in the steering gear, which is beneficial to reduce the force loss, but also enable the limiting hole 12 to radially limit the limiting column 22, and then enable at least one of the first connecting shell 110 and the second connecting shell 120 to radially limit the input shaft shell 20, so as to ensure the structural stability of the input shaft shell 20 between the first connecting shell 110 and the second connecting shell 120.

[0051] Further, the guide groove is provided on the inner wall of the limiting hole 12, and the guide protrusion is provided on the limiting column 22, and when the limiting column 22 extends into the limiting hole 12, the guide groove and the guide protrusion can be guided and matched. Specifically, the inner wall of the limiting hole 12 can provide a stable and reliable setting position for the guide groove, the limiting column 22 can provide a stable and reliable setting position for the guide protrusion, the guide groove can provide a matching space for the guide protrusion, and the guiding matching between the guide protrusion and the portion of the inner wall of the limiting groove corresponding to the guide groove can make the guiding matching between the guide protrusion and the guide groove, and the torque can be transmitted between the guide protrusion and the portion of the inner wall of the limiting groove corresponding to the guide groove, so that the torque can be transmitted between the input shaft housing 20 and at least one of the first connection housing 110 and the second connection housing 120.

[0052] Combination Figure 2 , Figure 7 , Figure 8 and Fig. 9As shown, the steering gear housing 100 further includes a fastener 30, a first through hole 131 is provided on at least one of the first connection housing 110 and the second connection housing 120, a second through hole 231 is provided on the input shaft housing 20, and the second through hole 231 corresponds to the first through hole 131, and the fastener 30 sequentially penetrates the first through hole 131 and the second through hole 231 to connect and fix at least one of the first connection housing 110 and the second connection housing 120 to the input shaft housing 20. Specifically, the first through hole 131 is provided on at least one of the first connection housing 110 and the second connection housing 120, and the structure of the first through hole 131 is simple and convenient to process, and the second through hole 231 is provided on the input shaft housing 20, and the structure of the second through hole 231 is simple and convenient to process, thereby facilitating the production convenience of the steering gear housing 100.

[0053] Furthermore, the first through-hole 131 and the second through-hole 231 correspond to each other, which can facilitate the fastener 30 to pass through the first through-hole 131 and the second through-hole 231 in sequence, thereby improving the assembly convenience of the steering gear housing 100. By sequentially penetrating the first through-hole 131 and the second through-hole 231 by the fastener 30, the input shaft housing 20 can be connected and fixed to at least one of the first connecting housing 110 and the second connecting housing 120. This can not only enhance the connection reliability between the input shaft housing 20 and at least one of the first connecting housing 110 and the second connecting housing 120, but also ensure that the position of the input shaft housing 20 relative to the first connecting housing 110 and the second connecting housing 120 is fixed, so that the input shaft housing 20 can always be connected between the first connecting housing 110 and the second connecting housing 120 at a preset position, and the input shaft angle of the steering gear can be fixed to ensure the structural stability and working reliability of the steering gear in the vehicle.

[0054] Combination Figure 3-Figure 5As shown, at least one of the first connecting shell 110 and the second connecting shell 120 is provided with a first connecting flange 13, the input shaft shell 20 is provided with a second connecting flange 23, the first through-hole 131 is provided on the first connecting flange 13, the second through-hole 231 is provided on the second connecting flange 23, and the first connecting flange 13 and the second connecting flange 23 correspond to each other so that the first through-hole 131 and the second through-hole 231 correspond to each other. Specifically, the second connecting flange 23 is arranged to fit in correspondence with the first connecting flange 13, which can increase the contact area between the input shaft housing 20 and at least one of the first connecting housing 110 and the second connecting housing 120, and can make the input shaft housing 20 and at least one of the first connecting housing 110 and the second connecting housing 120 in close contact, which can not only improve the connection reliability between the input shaft housing 20 and at least one of the first connecting housing 110 and the second connecting housing 120, but also improve the connection stability between the input shaft housing 20 and at least one of the first connecting housing 110 and the second connecting housing 120, thereby improving the structural reliability of the steering gear housing 100 and the torque transmission efficiency between the steering gear housing 100.

[0055] Furthermore, the first connection flange 13 can provide a stable and reliable setting position for the first through-hole 131, and the second connection flange 23 can provide a stable and reliable setting position for the second through-hole 231, so that the fastener 30 can be stably connected to the first connection flange 13 and the second connection flange 23. When the first connection flange 13 and the second connection flange 23 correspond to each other, the first through-hole 131 and the second through-hole 231 can correspond to each other, so that it is convenient for the fastener 30 to sequentially penetrate the first through-hole 131 and the second through-hole 231, and the reliability of the fastener 30 connecting the first connection flange 13 and the second connection flange 23 can be ensured, thereby improving the connection reliability of the input shaft housing 20 and at least one of the first connection housing 110 and the second connection housing 120.

Specifically, the correspondence between the first through hole 131 and the second through hole 231 is actually the correspondence between the circular hole and the strip hole, and the length of the strip hole exceeds the diameter of the circular hole. In this way, when the circular hole and the strip hole partially correspond, it is not only convenient for the fastener 30 to pass through the circular hole and the strip hole in sequence, but also the circular hole and the fastener 30 can be moved relative to the strip hole together to adapt to the position of the input shaft housing 20 between the first connection housing 110 and the second connection housing 120 to be rotatably adjusted. After the position adjustment of the input shaft housing 20 relative to the first connection housing 110 and the second connection housing 120 is completed, the fastener 30 can be rotated again, and the input shaft housing 20 can be connected and fixed between the first connection housing 110 and the second connection housing 120 at a preset angle, so that the input shaft angle of the steering gear can be kept fixed to complete the adjustment of the input shaft angle of the steering gear.

Specifically, a plurality of first through-holes 131 and a plurality of second through-holes 231 are arranged, so that the connection position between the input shaft housing 20 and at least one of the first connection housing 110 and the second connection housing 120 can be increased, and the connection reliability between the input shaft housing 20 and at least one of the first connection housing 110 and the second connection housing 120 can be improved, so as to help improve the structural reliability of the steering gear housing 100. In addition, multiple first through holes 131 are arranged circumferentially on the outer side of the limiting hole 12, and multiple second through holes 231 are arranged circumferentially on the outer side of the limiting column 22, so that the connection position between the first connecting flange 13 and the second connecting flange 23 can be circumferentially spaced on the end surfaces of the first connecting flange 13 and the second connecting flange 23. This not only facilitates the opening of the first through holes 131 and the second through holes 231, but also facilitates the connection of the fastener 30 on the steering gear housing 100, and also improves the force uniformity of the first connecting flange 13 and the second connecting flange 23. During the torque transmission process, it is beneficial to improve the structural stability of the input shaft housing 20 between the first connecting housing 110 and the second connecting housing 120, and can reduce the transmission loss of the torque in the steering gear housing 100, thereby reducing the torque fluctuation, which is beneficial to improving the steering performance of the vehicle.
