TECHNICAL FIELD

[0001] The utility model relates to the technical field of automobile industry, concretely is a quick release type wheel hub system. BACKGROUND

[0002] The traditional wheel hub adopts a threaded connection mode, is connected with the shaft body by four or five bolts and is locked to the wheel hub. The wheel hub connection system can cause the wheel hub and the shaft body to rust and be locked, which results in the wheel hub being unable to be disassembled. In addition, the disassembly requires professional tools and is time-consuming and laborious. The central locking wheel hub is mainly applied to racing cars and high-end performance cars, but it is difficult to disassemble. It needs a large force and an expensive special tool to be dismounted or screwed on. This is not good for most daily road cars. If a problem occurs, it is difficult to solve the problem by oneself. Only a tow truck can be waited for. SUMMARY

[0003] The utility model aims at providing a quick release type wheel hub which can be quickly and conveniently disassembled.

[0004] To achieve the above-mentioned purpose, the technical scheme of the utility model is as follows.

[0005] A quick release type wheel hub system, comprising a shaft body and a wheel hub, a brake disc is installed on one end of the shaft body through a flange, an inner groove of the shaft body is formed on the outer surface of the shaft body, a plurality of spline grooves are formed on the other end of the shaft body in a coaxial array, and the inner groove of the shaft body is located between the two ends of the shaft body. A plurality of splines are coaxially arranged on the inner wall of the wheel hub mounting portion, the splines are matched with the spline grooves, a sleeve is sleeved on the outer surface of the wheel hub mounting portion, a spring is sleeved on the outer surface of the wheel hub mounting portion, and the two ends of the spring are respectively in abutment with the wheel hub and the sleeve. When the mounting portion is installed on the shaft body, the spring provides a restoring force for the sleeve along the wheel hub axis to the flange. A plurality of through grooves are coaxially arranged on the surface of the wheel hub mounting portion, a rigid ball is arranged in the through groove, and an inner groove of the sleeve is formed on the inner wall of the sleeve.

[0006] It can be seen that the inner groove of the sleeve is aligned with the rigid ball by sliding the sleeve, then the wheel hub is pulled outward, the inclined surface of the inner wall of the inner groove of the shaft body pushes the rigid ball to the position of the inner groove of the sleeve, at this time the rigid ball is separated from the inner groove of the shaft body, the locking function of the shaft body is lost, and the wheel hub can be quickly disassembled. When installing, the spring is compressed by sliding the sleeve, then the mounting portion of the wheel hub is sleeved on the shaft body, the rigid ball enters the inner groove of the shaft body, and the inner wall of the sleeve is used to limit the rigid ball, so as to achieve the purpose of quick installation. The owner can separate or connect the wheel hub and the shaft body without using traditional professional tools, especially in an emergency or when the wheel hub needs to be frequently disassembled. At the same time, the rusting of the wheel hub and the shaft body is prevented, which prevents the wheel hub from being unable to be disassembled, and the replacement time and operation difficulty can be greatly reduced.

[0007] The spline groove is arranged on the shaft body far from the flange, and the corresponding spline is arranged at the bottom of the inner cavity of the mounting part, so that the spline and the spline groove are easily formed, and the processing difficulty is reduced. The spline is beneficial to improving the structural strength of the mounting part.

[0008] Further, a first groove is arranged on the outer surface of the hub mounting part, and a first sealing ring is arranged in the first groove.

[0009] Under the thrust of the spring, the end of the sleeve abuts against the first sealing ring, so as to seal the space between the sleeve and the hub mounting part, and the first sealing ring also limits the sleeve and prevents it from falling off the hub mounting part, thereby ensuring the stability of the connection between the hub and the shaft body.

[0010] Further, a second groove is arranged on the inner wall of the hub mounting part, and a second sealing ring is arranged in the second groove.

[0011] The second sealing ring is arranged to seal the space between the hub mounting part and the shaft body.

[0012] Further, a hub cover is arranged on the surface of the hub, and the hub cover is threadedly connected with the hub.

[0013] The hub cover is conveniently disassembled and assembled through the threaded connection, and the quick-release hub connection system has a split structure design and is modular and customizable. Due to the relatively simple and modular structure, manufacturers and vehicle owners can select different components according to specific needs, thereby realizing customization of the hub, the hub cover and the brake disc. This flexibility allows the vehicle to better adapt to different purposes and individual needs, meeting the needs of different users.

[0014] Further, a first boss is arranged on the outer surface of the sleeve.

[0015] The first boss provides a force point, so that the sleeve can be easily slid by hand and the spring force can be overcome.

[0016] Further, a second boss is arranged on the outer surface of the hub mounting part, and when the sleeve abuts against the second boss, the groove in the sleeve corresponds to the through groove.

[0017] The second boss has a positioning effect, thereby improving the disassembly efficiency of the hub. DETAILED DESCRIPTION

DETAILED DESCRIPTION

[0026] The utility model is described in detail below in combination with the drawings.

[0027] As Figures 1-7 shown, a quick-release type hub system, comprising a shaft body 102 and a hub 101, one end of the shaft body 102 is installed with a brake disc 100 through a flange 120, the outer surface of the shaft body 102 is provided with a shaft body inner groove 103, the other end of the shaft body 102 is provided with a plurality of spline grooves 104 in coaxial array, and the shaft body inner groove 103 is located between the two ends of the shaft body 102. The inner wall of the installation part 1011 of the hub 101 is installed with a plurality of splines 105 in coaxial array, and the spline 105 is matched with the spline groove 104, the outer surface of the installation part 1011 of the hub 101 is sleeved with a sleeve 106, the outer surface of the installation part 1011 of the hub 101 is sleeved with a spring 107, and the two ends of the spring 107 are respectively abutted with the hub 101 and the sleeve 106. When the installation part 1011 is installed on the shaft body 102, the spring 107 provides a reset force for the sleeve 106 along the axis of the hub 101 to the flange 120. The surface of the installation part 1011 of the hub 101 is provided with a plurality of through grooves 108 in coaxial array, the inside of the through groove 108 is provided with a rigid ball 109, and the inner wall of the sleeve 106 is provided with a sleeve inner groove 110.

[0028] The owner only needs to pull the sleeve 106 outward to disassemble and assemble the hub 101. When disassembling, the slidable sleeve 106 compresses the spring 107, and the groove 110 in the sleeve aligns with the rigid ball 109. Then, the hub 101 is pulled outward, and the inclined surface of the inner groove 103 of the shaft body pushes the rigid ball 109 to the position of the groove 110 in the sleeve. At this time, the rigid ball 109 is separated from the inner groove 103 of the shaft body, and the locking function of the shaft body 102 is lost, so that the hub 101 can be quickly disassembled. When assembling, the hub 101 and the shaft body 102 are properly positioned, the sleeve 106 is pulled, and the hub 101 is pushed inward until a "click" sound is heard.

[0029] Specifically, the outer surface of the hub 101 mounting portion 1011 is provided with a first groove 200, and the first groove 200 is provided with a first sealing ring 201. Under the pushing force of the spring 107, the end of the sleeve 106 abuts against the first sealing ring 201, thereby sealing the space between the sleeve 106 and the hub 101 mounting portion 1011. In addition, the first sealing ring 201 also limits the sleeve 106, preventing it from falling off the mounting portion 1011 of the hub 101, thereby ensuring the stability of the connection between the hub 101 and the shaft body 102.

[0030] Specifically, the inner wall of the hub 101 mounting portion 1011 is provided with a second groove 300, and the second groove 300 is provided with a second sealing ring 301. The second sealing ring 301 seals the space between the hub 101 mounting portion 1011 and the shaft body 102.

[0031] Specifically, the hub cover 400 is mounted on the surface of the hub 101, and the hub cover 400 is connected with the hub 101 by screwing. The hub cover 400 can be easily disassembled and assembled by screwing. In addition, the quick-release hub connection system adopts a split structure design, which is modular and customizable. Due to its relatively simple structure and modularity, manufacturers and owners can choose different components according to specific needs, thereby realizing the customization of the hub 101, the hub cover 400, and the brake disc 100. This flexibility allows vehicles to better adapt to different purposes and individual needs, meeting the needs of different users.

[0032] Specifically, the outer surface of the sleeve 106 is provided with a first boss 500. The first boss 500 provides a force point, which facilitates the sliding of the sleeve 106 by hand and overcomes the elastic force of the spring 107.

[0033] Specifically, the outer surface of the hub 101 mounting portion 1011 is provided with a second boss 600, when the sleeve 106 is in abutment with the second boss 600, the sleeve inner groove 110 corresponds to the through groove 108, through the setting of the second boss 600, positioning effect can be achieved, improve the disassembly efficiency of the hub 101.
