Abstract
Description
Technical Field
[0001] This utility model relates to the field of vehicle component technology, and more specifically, to a novel fully floating rear axle head locking structure. Background Technology
[0002] The axle head is a key component in the rear axle assembly of a vehicle. It is mainly responsible for connecting the wheels to the rear axle half-shaft, transmitting power, and supporting the weight of the vehicle.
[0003] Currently, when the rear axle head is installed with the wheel hub, the wheel hub rotates on the rear axle head via a bearing inside the wheel hub. After the bearing is installed on the rear axle head, it needs to be locked and fixed by an external structure to maintain the stability of the wheel hub during rotation. The existing locking method is to use the bending of the nut and the edge of the washer to lock it in the corresponding slot of the nut. This locking strength is low and the thread may come loose, which affects the stability of the locking. Therefore, it is necessary to propose a new fully floating rear axle head locking structure to solve the above problems. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides a novel locking structure for the fully floating rear axle head, which aims to improve the existing locking method that uses the bending of the nut and the edge of the washer to lock the axle at the corresponding slot of the nut. This method has low locking strength and is prone to thread slippage, which affects the stability of the locking.
[0005] This utility model is implemented as follows: This utility model provides a novel fully floating rear axle head locking structure, including a rear axle head and a wheel hub mounted on the rear axle head, as well as a locking structure for locking the wheel hub.
[0006] The bearing is placed inside the wheel hub and is sleeved on the rear axle axle head; the locking structure includes a nut, a locking plate and a bolt, the nut is screwed on the rear axle axle head and is located on one side of the bearing, the locking plate is sleeved on the rear axle axle head and the locking plate is fixed to the nut by the bolt.
[0007] In one embodiment of this utility model, the rear axle head is provided with an external thread that matches the nut, and the nut is screwed onto the external thread.
[0008] In one embodiment of this utility model, the nut has a regular hexagonal cross-section, and threaded holes are symmetrically provided on the nut. The locking plate has a through hole corresponding to the threaded hole, and the bolt passes through the through hole and is threaded into the inside of the threaded hole.
[0009] In one embodiment of this utility model, the lock piece has a notch inside, and the notch is distributed circumferentially on the lock piece.
[0010] In one embodiment of this utility model, a limiting protrusion is formed inside the locking plate, and a limiting groove matching the limiting protrusion is provided on the rear axle head, and the limiting protrusion is slidably engaged in the limiting groove.
[0011] The beneficial effects of this utility model are as follows: This utility model provides a novel fully floating rear axle head locking structure. In use, the bearing is fitted onto the rear axle head, and then the wheel hub is fitted onto both the bearing and the rear axle head. Under the action of the bearing, the wheel hub can rotate on the rear axle head. Then, the nut is threaded onto the external thread of the rear axle head to limit and fix the bearing. Next, the limiting protrusion on the limiting locking plate is aligned with the limiting groove, and the limiting locking plate is fitted onto the rear axle head. Finally, a bolt is threaded through the through hole and connected to the inside of the threaded hole for fixation. This increases the locking strength and stability during locking, reduces the occurrence of thread slippage, and thus improves the stability of the wheel hub and makes it more convenient to use.

[0015] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Example
[0016] Please see Figures 1-3 This utility model provides a technical solution: a novel fully floating rear axle head locking structure, including a rear axle head 100 and a wheel hub 200 mounted on the rear axle head 100, and a locking structure 300 for locking the wheel hub 200.
[0017] Please see Figure 1 and Figure 2 The hub 200 contains a bearing 210, which is fitted onto the rear axle head 100.
[0018] The rear axle head 100 has an external thread 101 that matches the nut 310. The nut 310 is screwed onto the external thread 101. The external thread 101 allows the nut 310 to be installed on the rear axle head 100 and limits the bearing 210.
[0019] Please see Figures 1-3 The locking structure 300 includes a nut 310, a locking plate 320, and a bolt 330. The nut 310 is screwed onto the rear axle head 100 and is located on one side of the bearing 210. The locking plate 320 is sleeved on the rear axle head 100 and is fixed to the nut 310 by the bolt 330.
[0020] The nut 310 has a regular hexagonal cross-section and symmetrical threaded holes 311 on it. The locking plate 320 has a through hole 321 corresponding to the threaded hole 311. The bolt 330 passes through the through hole 321 and is threaded into the inside of the threaded hole 311. Here, the bolt 330 is used to directly fix the locking plate 320 and the nut 310, which can improve the locking strength, reduce the occurrence of thread slippage, and make the hub 200 more secure and stable when rotating.
[0021] The locking plate 320 has a notch 322 inside, which is circumferentially distributed in the locking plate 320. The notch 322 is designed to save materials without affecting its strength. The locking plate 320 has a limiting protrusion 340 inside, and the rear axle head 100 has a limiting groove 102 that matches the limiting protrusion 340. The limiting protrusion 340 is slidably engaged in the limiting groove 102. By using the limiting protrusion 340 and the limiting groove 102, the through hole 321 can be aligned with the threaded hole 311, which makes it easier to install the bolt 330 and improves the convenience of use.
[0022] Specifically, the working principle of this new type of fully floating rear axle head locking structure is as follows: In use, the bearing 210 is fitted onto the rear axle head 100, and then the wheel hub 200 is fitted onto the bearing 210 and the rear axle head 100. Under the action of the bearing 210, the wheel hub 200 can rotate on the rear axle head 100. Then, the nut 310 is threaded onto the external thread 101 of the rear axle head 100, thereby limiting and fixing the bearing 210. Next, the limiting protrusion 340 on the limiting locking plate 320 is aligned with the limiting groove 102, and the limiting locking plate 320 is fitted onto the rear axle head 100. At this point, the bolt 330 is threaded through the through hole 321 and connected to the inside of the threaded hole 311 for fixation. This increases the locking strength and stability during locking, reduces the occurrence of thread slippage, and thus improves the stability of the wheel hub 200 and makes it more convenient to use.
[0023] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
