Description

Technical Field

[0001] The utility model belongs to the technical field of vehicle engineering, and in particular relates to a connecting bracket for an automobile steering gear. Background Art

[0002] The steering gear is a crucial component of a vehicle's steering system. Its primary function is to amplify and reduce the torque applied by the driver to the steering wheel. This torque is then transmitted to the steering transmission mechanism, which controls the steering of the vehicle's front or rear wheels. The steering gear is typically mounted at the front of the vehicle frame to facilitate the transmission of torque from the steering wheel. When the vehicle is in motion, especially when heavily loaded, the steering shaft of the steering wheel transmits significant force to the steering gear. This necessitates that the steering gear's mounting bracket be able to withstand significant loads and possess high strength.

[0003] On current new energy heavy-duty hydrogen electric trucks, one end of the steering gear bracket is connected to the front extension beam of the vehicle body, and the other end is equipped with a steering gear and an electric intelligent steering assist system. The steering gear bracket mostly adopts a welded splicing structure. The steering gear bracket has many redundant structures, a large overall weight, a large occupied volume, and limited installation space, which makes it difficult to meet the needs of lightweight truck structures. Utility Model Content

[0004] In order to solve the technical problems existing in the prior art, the utility model provides an automobile steering gear bracket, which has a rationally arranged bracket structure, a light overall weight, and stable structural performance.

[0005] To achieve the above objectives, the present invention employs a technical solution: a vehicle steering gear bracket comprising a first bracket and a second bracket, the first bracket and the second bracket being connected via an intermediate bracket, the first bracket, the second bracket, and the intermediate bracket being integrally formed. While ensuring structural strength, the intermediate bracket is hollow, with one end of the intermediate bracket smoothly connected to the first bracket and the other end of the intermediate bracket smoothly connected to the second bracket to avoid stress concentration.

[0006] The first bracket and the middle bracket are connected by a first reinforcing rib, which can increase the connection strength between the first bracket and the middle bracket; the first bracket and the middle bracket are connected by a second reinforcing rib, which can increase the connection strength between the second bracket and the middle bracket. The first bracket is provided with four first bases, which are located at the four corners of the first bracket. Each first base has a first connecting through hole, and each first connecting through hole is a countersunk hole. The first bracket is provided with three second bases, which are located on one side of the first bracket. The second base has a second connecting through hole, and the first bracket has a semicircular weight-reducing hole. The first and second reinforcing ribs are located on both sides of the middle bracket, and the semicircular weight-reducing hole is located between the first and second reinforcing ribs.

[0007] Five third bases are provided on the second bracket, and the five third bases are arranged around the edge of the second bracket. A third connecting through hole is opened on the third base, and a second weight-reducing groove is opened on the second bracket. The second weight-reducing groove is smoothly connected to the inner hole of the middle bracket to avoid stress concentration.

[0008] The intermediate bracket is placed at one end of the first bracket. In order to meet the installation space requirements, the intermediate bracket is arranged inclined to the first bracket. The first bracket is staggered relative to the second bracket. The semicircular weight-reducing hole is placed at the other end of the first bracket. The semicircular weight-reducing hole is arranged away from the intermediate bracket to ensure the structural strength and stability of the entire first bracket. The semicircular weight-reducing hole is placed between two of the first bases.

[0009] The middle bracket is arranged tilted relative to the second bracket to meet the requirements of the installation space.

[0010] One of the second bases is arranged on the first reinforcement rib and perpendicular to the first bracket, the other two second bases are arranged horizontally, the vertically arranged second base is placed between the two horizontally arranged second bases, and the three second bases are all arranged between two of the first bases, reducing the installation space of the power assist system.

[0011] A first arc segment is provided on one side of the first reinforcing rib, and the first arc segment forms an inwardly concave structure, which reduces the weight of the entire structure while ensuring the strength of the connection structure between the first bracket and the intermediate bracket.

[0012] A second arc segment is provided on one side of the second reinforcing rib, and the second arc segment forms an inwardly concave structure, which reduces the weight of the entire structure while ensuring the strength of the connection structure between the first bracket and the intermediate bracket.

[0013] A first weight-reducing groove is provided on the first bracket and is arranged at the bottom of the first bracket. The first weight-reducing groove is smoothly connected to the inner hole of the middle bracket, which further reduces the weight of the entire structure and avoids stress concentration.

[0014] A third weight-reducing groove is provided on the back side of the second bracket. The third weight-reducing groove conforms to the structural arrangement of the second bracket, which reduces the weight without affecting the structural strength of the second bracket.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The first bracket, the second bracket and the intermediate bracket of the utility model are integrally cast, eliminating the stamping and welding process of the original structure, realizing the integration of multiple assembly functions, the overall structure is compact, the unit weight of the product is greatly reduced, the vehicle turning radius is small, the turning resistance is small, the smooth operation of the steering system is ensured, and the overall safety factor is high.

[0017] 2. The material of the present invention is upgraded from ZG310-570 to ZG650-830, which not only improves the quality of the bracket but also meets the requirements of lightweight design and increases the safety factor by 22.1%.

[0018] 3. The utility model reduces the development cost of the entire steering gear bracket, ensures versatility, and saves layout space. BRIEF DESCRIPTION OF THE DRAWINGS
