[0036] The following describes a steering gear bracket 1 according to an embodiment of the present utility model with reference to the accompanying drawings.

[0037] like Figure 1-Figure 7 As shown, the steering gear bracket 1 is constructed as a flat plate structure and a steering gear output shaft hole 101 is constructed at the center. The inner side of the steering gear bracket 1 is suitable for installation on the front connecting beam of the frame, and the outer side of the steering gear bracket 1 is suitable for installing the steering gear 10. Among them, the inner side surface of the steering gear bracket 1 is constructed with an inner weight reduction groove 100, and the outer side surface of the steering gear bracket 1 is constructed with an outer weight reduction groove 200, and the inner weight reduction groove 100 and the outer weight reduction groove 200 are staggered. The steering gear bracket 1 is tilted relative to the side of the frame, that is, the lower part of the steering gear bracket 1 is closer to the frame longitudinal beam, and the upper part of the steering gear bracket 1 is farther from the frame longitudinal beam.

[0038] For example, the inner weight-reducing grooves 100 are arranged in multiple rows at equal intervals, and the outer weight-reducing grooves 200 are arranged in multiple rows at equal intervals. The inner weight-reducing grooves 100 and the outer weight-reducing grooves 200 are alternately arranged in the vertical direction to be evenly arranged on opposite sides of the flat plate structure. The steering gear bracket 1 is configured with a steering gear output shaft hole 101 at the center position, which is suitable for penetrating the steering gear output shaft hole 101. The inner weight-reducing grooves 100 and the outer weight-reducing grooves 200 are distributed around the steering gear output shaft hole 101. The outer position of the steering gear bracket 1 is penetrated by fasteners to fix the steering gear 10 with the steering gear bracket 1.

[0039] According to the steering gear bracket 1 of the embodiment of the utility model, the inner side surface of the steering gear bracket 1 is configured with an inner weight reduction groove 100, and the outer side surface is configured with an outer weight reduction groove 200, and the inner weight reduction groove 100 and the outer weight reduction groove 200 are arranged in a staggered manner. The structure of the inner weight reduction groove 100 and the outer weight reduction groove 200 can effectively reduce the material usage of the steering gear bracket 1, thereby reducing the overall weight of the steering gear bracket 1 and reducing the overall total weight of the vehicle. At the same time, the inner weight reduction groove 100 and the outer weight reduction groove 200 are arranged in a staggered manner, and the structural strength of the steering gear bracket 1 can be maintained while achieving a lightweight structure. Each position of the steering gear bracket 1 has a certain material, and the weight reduction of the steering gear bracket 1 is improved to be more uniform. Therefore, while ensuring the structural strength of the steering gear bracket 1, the weight of the steering gear bracket 1 itself is effectively reduced, and the total weight of the vehicle is reduced. Reducing the weight of the vehicle helps to improve fuel efficiency, reduce fuel consumption, and achieve energy-saving and environmental protection effects. In addition, the steering gear bracket 1 is tilted to the frame to ensure the installation angle of the steering gear.

[0040] Therefore, the steering gear bracket 1 according to the embodiment of the utility model has the advantages of reducing the weight of the whole vehicle, reducing the manufacturing cost, and being energy-saving and environmentally friendly.

[0041] In some specific embodiments of the present invention, Figure 3 , Figure 5 and Figure 6 As shown, the cross-section of the inner weight-reducing groove 100 and the outer weight-reducing groove 200 along the vertical direction is configured into a trapezoid. The inner weight-reducing groove 100 and the outer weight-reducing groove 200 of the trapezoidal structure can ensure that the steering gear bracket 1 has sufficient structural strength while reducing the amount of material used. The trapezoidal structure has good bearing capacity, which helps to improve the bending and compression resistance of the steering gear bracket 1, and ensure the safety and reliability of the steering gear bracket 1 during use. The trapezoidal inner weight-reducing groove 100 and the outer weight-reducing groove 200 can also reduce the stress concentration of the steering gear bracket 1, which helps to extend the service life of the steering gear bracket 1.

[0042] In some specific embodiments of the present invention, Figure 5 and Figure 6As shown, the outer weight-reducing groove 200 includes a first upper groove 210, a middle groove 220 and a first lower groove 230. The first upper groove 210, the middle groove 220 and the first lower groove 230 are arranged at intervals in the vertical direction. The inner weight-reducing groove 100 includes a second upper groove 110 and a second lower groove 120. The second upper groove 110 is located between the first upper groove 210 and the middle groove 220 in the vertical direction, and the second lower groove 120 is located between the middle groove 220 and the first lower groove 230 in the vertical direction.

[0043] For example, a weight-reducing groove is constructed on the side of the outer side of the steering gear bracket 1 opposite to the middle groove 220, and a weight-reducing groove is also constructed on the side of the inner side of the steering gear bracket 1 opposite to the second upper groove 110 and the second lower groove 120. The weight-reducing groove on the outer side is located between the weight-reducing grooves on the inner side, and the grooves are arranged in a staggered manner. The staggered inner weight-reducing grooves 100 and outer weight-reducing grooves 200 can reduce the weight of the steering gear bracket 1 while maintaining the structural integrity and stability of the steering gear bracket 1, ensuring that the steering gear bracket 1 has sufficient structural strength in the process of bearing steering force and other forces, thereby improving the stability and reliability of the steering gear bracket 1.

[0044] In some specific embodiments of the present invention, Figure 7 As shown, the maximum thickness of the steering gear bracket 1 is 14mm to 16mm. The steering gear bracket 1 will bear the steering force from the steering gear 10 and other components during the driving of the vehicle. Controlling the wall thickness of the steering gear bracket 1 within an appropriate range can ensure that the steering gear bracket 1 has sufficient structural strength to withstand the stress and load generated during the steering process and ensure the stability and safety of the vehicle during driving. At the same time, excessive or insufficient wall thickness may cause the steering gear bracket 1 to easily crack or deform during use. Controlling the appropriate wall thickness can extend the service life of the steering gear bracket 1 and reduce the cost of maintenance and replacement.

[0045] In some specific embodiments of the present invention, Figure 7 As shown, the thickness of the steering gear bracket 1 at the inner weight-reducing groove 100 and the outer weight-reducing groove 200 is 5 mm to 7 mm.

[0046] The weight of the steering gear bracket 1 can be reduced by the structure of the inner weight-reducing groove 100 and the outer weight-reducing groove 200. By controlling the wall thickness of the inner weight-reducing groove 100 and the outer weight-reducing groove 200 within a certain range, the amount of material used can be reduced, the steering gear bracket 1 can be lightweighted, and the fuel economy, acceleration performance and handling performance of the vehicle can be improved. By controlling the wall thickness of the inner weight-reducing groove 100 and the outer weight-reducing groove 200 within a suitable range, the steering gear bracket 1 can be lightweighted while ensuring that the steering gear bracket 1 has sufficient structural strength to withstand normal working loads, avoid excessive weight reduction and structural weakening, and strike a good balance between lightweight structure and structural strength.

[0047] In some specific embodiments of the present invention, Figure 1-Figure 6 As shown, the outer contour of the steering gear bracket 1 is configured as a polygon, and the steering gear bracket 1 is provided with a steering gear mounting hole 300 and a vehicle frame mounting hole 400 at the corners of the formed polygon.

[0048] The central axis of the steering gear mounting hole 300 extends perpendicularly to the surface of the steering gear bracket 1, and the steering gear mounting hole 300 is suitable for passing a first fastener to install the steering gear 20. The central axis of the frame mounting hole 400 extends obliquely to the normal line of the surface of the steering gear bracket 1, and the frame mounting hole 400 is suitable for passing a second fastener to be installed on the front connecting beam of the frame.

[0049] The outer contour of the steering gear bracket 1 is designed to be a polygonal shape. Compared with the traditional shape, the polygonal structure can better share the external force and reduce deformation, which helps to improve the structural strength of the steering gear bracket 1 and enhance the stability and reliability of the steering gear bracket 1 during operation.

[0050] The steering gear mounting hole 300 and the frame mounting hole 400 are arranged at the polygonal corners, which can effectively utilize the space and provide a stable mounting position. By inserting the first fastener and the second fastener to install the steering gear 10 and connect the front connecting beam of the frame, the steering gear bracket 1 and related components can be effectively fixed and stabilized to ensure that they will not loosen or move abnormally during driving, thereby improving the safety and reliability of the vehicle.

[0051] In some specific embodiments of the present invention, Figure 1-Figure 6 As shown, a steering gear mounting ring 301 is configured on the outer peripheral side of the steering gear mounting hole 300, and the end surface of the steering gear mounting ring 301 is suitable for supporting the steering gear 10. A frame mounting ring 401 is configured on the outer peripheral side of the frame mounting hole 400, and the end surface of the frame mounting ring 401 is suitable for supporting the front connecting beam of the frame.

[0052] The steering gear mounting ring 301 and the frame mounting ring 401 are suitable for supporting the steering gear 10 and the front connecting beam of the frame. Through the structure of the steering gear mounting ring 301 and the frame mounting ring 401, a uniform supporting force can be provided to ensure that the steering gear 10 and the front connecting beam of the frame can be firmly installed on the steering gear bracket 1 to prevent looseness or vibration during vehicle driving.

[0053] The frame mounting ring 401 is an inclined ring, which can better adapt to the inclined setting of the frame front connecting beam, making the installation of the frame front connecting beam more stable. The structure of the inclined ring can not only provide good support performance, but also make the connection between the steering gear bracket 1 and the frame front connecting beam more secure, improve the accuracy and reliability of assembly, and improve the safety of vehicle driving.

[0054] In some specific embodiments of the present invention, Figure 1-Figure 6 As shown, there are multiple steering gear mounting holes 300 arranged in a rectangular shape, and at least some of the steering gear mounting holes 300 are suitable for passing the first fastener to install the steering gear 10. There are multiple frame mounting holes 401 and they are respectively located at the front side of the frontmost steering gear mounting hole 300 and the rear side of the rearmost steering gear mounting hole 300, and the central axes of the multiple frame mounting holes 400 are parallel to each other.

[0055] There are multiple steering gear mounting holes 300 arranged in a rectangular shape, which can ensure that the spacing between the steering gear mounting holes 300 is uniform, so that the installation position of the steering gear on the steering gear bracket 1 is more stable and evenly distributed. At the same time, it can ensure that the force applied to the steering gear bracket 1 during operation is evenly distributed, effectively avoiding the stress concentration problem caused by uneven local force, and improving the durability and stability of the steering gear bracket 1.

[0056] There are multiple frame mounting holes 400, which improve the connection stability and reliability between the front connecting beam of the frame and the steering gear bracket 1, and ensure the stability and safety of the vehicle during driving.

[0057] In some specific embodiments of the utility model, the steering gear bracket 1 is a ductile iron part. Specifically, the material with the grade QT800-5 can be used, which can ensure sufficient structural strength of the steering gear bracket 1 while setting a thinner wall thickness. Ductile iron is a high-strength and high-rigidity material, suitable for occasions where parts are required to have high load-bearing capacity and deformation resistance. The steering gear bracket 1 needs to withstand steering force and road impact, etc. The use of ductile iron material can ensure that the steering gear bracket 1 has sufficient strength and rigidity, improve the service life and reliability of parts, and at the same time, it is cheaper under the condition of selecting the same structural strength, and has better economic selectivity. Ductile iron parts have good wear resistance and corrosion resistance, which enables the steering gear bracket 1 to maintain stable performance in harsh working environments.
