Description

Technical Field

[0001] This utility model belongs to the field of automobile assembly, and specifically relates to a lifting bracket for a recirculating ball steering gear. Background Technology

[0002] In the automotive assembly workshop, workers must manually handle and lift the recirculating ball steering gear onto the vehicle frame. Because of its considerable weight, this process is strenuous for workers, resulting in low overall assembly efficiency and posing a safety hazard of the steering gear falling. This is especially true for electric power steering gears, which integrate motors and controllers, weighing even more, sometimes around 20kg, making the current manual lifting method even less suitable.

[0003] Current recirculating ball steering systems are generally used in commercial light trucks. Light trucks typically have a short front overhang, so highly integrated electric recirculating ball steering systems are chosen for ease of installation. These systems are usually installed vertically, with the input shaft facing upwards and the output shaft facing the left side of the vehicle. Because the steering system is a safety component and bears significant forces, it is generally quite heavy, making it difficult for a single worker to install independently.

[0004] For the end-mechanical limit of electric recirculating ball steering gear, the current industry design involves two or more people working together: one person holds the steering gear up, while another person passes the fixing bolt through the mounting point and then tightens it. This installation method has the following disadvantages: it is time-consuming and labor-intensive; the need to hold the steering gear during installation poses a risk of it falling; and even using tools to support the steering gear instead of holding it up makes it inconvenient for workers to pass the bolt through the hole. Utility Model Content

[0005] To address the above problems, this utility model provides a lifting bracket structure for an electric recirculating ball steering gear, which can effectively avoid the difficulty of steering gear installation. The specific technical solution is as follows:

[0006] A hoisting bracket for a recirculating ball steering gear includes three L-shaped lifting ring brackets, one J-shaped hook, and a lifting rope. The L-shaped lifting ring brackets are evenly arranged on the recirculating ball steering gear, and the J-shaped hook is connected to the three L-shaped lifting ring brackets and a crane via the lifting rope. The L-shaped lifting ring brackets are made of bent metal plates, with a through hole on each of the two bends. The lifting rope lifts the bracket and the steering gear together as a whole through the through holes.

[0007] The length of the J-type hook is adjustable via the rope length between the rope and the three L-type ring supports.

[0008] The L-shaped lifting ring brackets are arranged in a triangular pattern on the housing of the recirculating ball steering gear; they are fixed to the recirculating ball steering gear with bolts, forming a single unit with the recirculating ball steering gear. This avoids the need to modify the steering gear body mold.

[0009] Using this utility model of lifting bracket, the vertical projection of the center of gravity of the recirculating ball steering gear after lifting is located within the triangle formed by the vertical projections of the three lifting ring brackets. The angle of the steering gear after lifting can be adjusted by adjusting the length of the three lifting ropes, facilitating worker installation. The beneficial effects of this utility model are: in the final assembly workshop, workers only need to pass the hook through the through hole on the lifting ring bracket to lift the steering gear. Compared with the original manual lifting method, it effectively reduces the labor intensity; the multi-point lifting design makes it more stable after lifting, improving operational safety; the lifting rope length can be adjusted to the most suitable installation angle after lifting. It facilitates workers to insert bolts into the holes, and the lifting ropes do not need to be adjusted again after being adjusted according to the first sample, improving work efficiency; there is no need to change the steering gear shell mold, as the lifting ring bracket is fixed to the steering gear with bolts. It has the characteristics of simple structure, high versatility, and low cost. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] A lifting bracket for a recirculating ball steering gear includes three L-shaped lifting ring brackets 4-6, one J-shaped hook, and a lifting rope. The L-shaped lifting ring brackets are evenly arranged on the recirculating ball steering gear. The J-shaped hook is connected to the three L-shaped lifting ring brackets and a crane via the lifting rope. Each L-shaped lifting ring bracket is a bent metal plate with a through hole on each of the two bends. The lifting rope passes through these through holes to lift the bracket and the steering gear as a whole. The length of the lifting rope between the J-shaped hook and the three L-shaped lifting ring brackets is adjustable. The L-shaped lifting ring brackets are arranged in a triangular pattern on the outer shell of the recirculating ball steering gear and are bolted to the steering gear, forming a single unit. This eliminates the need for modification of the steering gear body mold.

[0016] This embodiment illustrates one arrangement of the lifting ring brackets. Three fixing bolts connecting the upper housing 2 and lower housing 1 of the recirculating ball steering gear secure the lifting ring brackets 4, 5, and 6 to the steering gear body, forming a single unit that is then delivered to the final assembly workshop. Assembly workers only need to hook the three lifting hooks onto the lifting ring brackets to perform the lifting and assembly. This improves the work efficiency of the final assembly workshop and reduces the workload of the workers.

[0017] The preferred embodiments of this patent have been described in detail above. However, this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this patent.
