Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of automobile accessories, and more specifically, to a wear-resistant steering yoke. Background Art
[0002] The steering knuckle is the hinge for steering the wheel and is generally fork-shaped. Coaxial holes are usually set in the upper and lower forks of the steering yoke and are matched with bearings to connect the kingpin. The bearings will wear due to external factors such as poor lubrication and overload, affecting the flexibility of the steering yoke. Since the bearings are usually interference fit with the coaxial holes of the steering yoke, when the bearings are taken out from the coaxial holes of the steering yoke, the coaxial holes of the steering yoke are easily worn. At this time, if a new bearing is installed, it will become loose. Therefore, the entire steering yoke needs to be replaced, which reduces the service life of the steering yoke. Summary of the invention
[0003] In order to overcome the deficiencies of the prior art, the utility model provides a wear-resistant steering yoke, which has the advantage of avoiding wear when the bearing is replaced.
[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a wear-resistant steering yoke, comprising a steering yoke body and a bearing, and also comprising:
[0005] An assembly structure, which is arranged on the steering yoke body and is used for disassembling and assembling the bearing;
[0006] Among them, the assembly structure includes a notch, which is arranged on the steering yoke body, a fixing rod is installed inside the notch, a return spring and an extrusion key are sleeved on the outer surface of the fixing rod, a circular hole is opened on one side of the steering yoke body, and a threaded rod is connected to the internal thread of the circular hole.
[0007] As a preferred technical solution of the utility model, the bearing is sleeved on the inner side of the notch, and when the extrusion key moves along the outer surface of the fixing rod, its inner wall can form a ring with the steering yoke body.
[0008] As a preferred technical solution of the utility model, the inner walls of the notch and the extrusion key are rough, and the extrusion key is in extrusion contact with the bearing.
[0009] As a preferred technical solution of the utility model, the return spring is elastically supported between the notch and the extrusion key.
[0010] As a preferred technical solution of the utility model, the top end of the threaded rod is in extrusion contact with the extrusion key.
[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:
[0012] The utility model enables the threaded rod to rotate and move left and right along the inner wall of the circular hole through the cooperation between the circular hole and the threaded rod, thereby driving the threaded rod to release the squeezing of the squeezing key. At this time, due to the design of the reset spring, the squeezing key has good elastic reset performance, thereby driving the squeezing key to separate from the bearing, thereby avoiding wear on the steering yoke body when the bearing is replaced.

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0019] like Figures 1 to 4 As shown, the utility model provides a wear-resistant steering yoke, comprising a steering yoke body 1 and a bearing 2, and also comprising:
[0020] An assembly structure, which is arranged on the steering yoke body 1 and is used for disassembling and assembling the bearing 2;
[0021] Among them, the assembly structure includes a slot 3, which is arranged on the steering yoke body 1. A fixing rod 4 is installed inside the slot 3. A return spring 5 and an extrusion key 6 are sleeved on the outer surface of the fixing rod 4. A circular hole 7 is opened on one side of the steering yoke body 1, and a threaded rod 8 is connected to the internal thread of the circular hole 7.
[0022] Through the cooperation between the circular hole 7 and the threaded rod 8, the threaded rod 8 can rotate along the inner wall of the circular hole 7 and move left and right, thereby driving the threaded rod 8 to release the squeezing of the squeezing key 6. At this time, due to the design of the reset spring 5, the squeezing key 6 has good elastic reset performance, thereby driving the squeezing key 6 to separate from the bearing 2, thereby avoiding wear on the steering yoke body 1 when replacing the bearing 2.
[0023] The bearing 2 is sleeved on the inner side of the notch 3 , and when the extrusion key 6 moves along the outer surface of the fixing rod 4 , its inner wall can form a ring with the steering yoke body 1 .
[0024] Through the cooperation between the extrusion key 6 and the fixing rod 4, the extrusion key 6 can move along the outer surface of the fixing rod 4. At the same time, through the cooperation between the bearing 2 and the slot 3, the outer surface of the bearing 2 can be covered by the extrusion key 6 to prevent the bearing 2 from falling off.
[0025] The inner walls of the notch 3 and the extrusion key 6 are rough, and the extrusion key 6 is in extrusion contact with the bearing 2 .
[0026] The bearing 2 can be clamped by the cooperation between the extrusion key 6 and the bearing 2. Meanwhile, the design of the notch 3 and the extrusion key 6 can increase the friction force when the bearing 2 is squeezed, thereby making the bearing 2 more stable.
[0027] The return spring 5 is elastically supported between the notch 3 and the extrusion key 6 .
[0028] Through the design of the reset spring 5, the squeezing key 6 has good elastic reset performance. At this time, since the reset spring 5 is in a compressed state, an elastic force will be applied to the squeezing key 6, thereby driving the squeezing key 6 to release the squeezing of the bearing 2, making it easier to disassemble the bearing 2.
[0029] The top end of the threaded rod 8 is in extrusion contact with the extrusion key 6 .
[0030] Through the cooperation between the threaded rod 8 and the extrusion key 6 , when the threaded rod 8 presses the extrusion key 6 , the extrusion key 6 will move along the outer surface of the fixed rod 4 , thereby driving the extrusion key 6 to position the bearing 2 .
[0031] The working principle and use process of this utility model:
[0032] When the bearing 2 is damaged, the staff can use a screwdriver to rotate the threaded rod 8. Through the cooperation between the round hole 7 and the threaded rod 8, the threaded rod 8 will rotate and move along the inner wall of the round hole 7, thereby driving the threaded rod 8 to release the squeezing of the squeezing key 6. At this time, the elastic force of the reset spring 5 will drive the squeezing key 6 to separate from the bearing 2, thereby avoiding wear on the steering yoke body 1 when replacing the bearing 2.
