DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] See also Figures 1 to 8The present invention provides a technical solution: a connection structure between a brake disc and a wheel hub bearing of a front steering axle of a truck, comprising a brake disc 1, a bearing sleeve 2 is installed at the center of the brake disc 1, a wheel hub bearing 9 is installed at one end of the inner wall of the bearing sleeve 2, an assembly plate 20 is fixedly installed on the inner wall of the bearing sleeve 2, an assembly column 8 is fixedly installed on the outer wall of the assembly plate 20, a control component is slidably installed on the outer wall of the assembly column 8, a riveting block 4 is slidably installed on the outer wall of the assembly plate 20, a positioning groove is provided on the bearing sleeve 2, a limiting groove is provided on the inner wall of the brake disc, the positioning groove and the limiting groove can form a butt connection, and the control component can control the riveting block 4 to move from the positioning groove to the limiting groove. When installing or disassembling, the control component controls the displacement of the riveting block 4 on the outer wall of the assembly plate 20. When the riveting block 4 is displaced, it will pass through the positioning groove and the limiting groove in turn to fix the brake disc and the wheel hub bearing 9, so that they can be connected more stably. In the present invention, the control component is set to control the riveting block to lock the brake disc, and it can also be disassembled more quickly when the brake disc needs to be repaired and inspected, avoiding damage to parts due to improper disassembly. Through the control component, the riveting block can be easily controlled to move from the positioning groove to the limiting groove, thereby achieving fixation with the brake disc. This design can lock or release the rotation at any time as needed, providing a more flexible way of use, and due to the installation method of the riveting block and the control component, it can be easily maintained and replaced. If the brake disc needs to be replaced or the force of the locking rotation needs to be adjusted, it is only necessary to adjust or replace the riveting block and the control component, without large-scale disassembly and maintenance of the entire system, thereby improving the user experience.

[0026] Two control component implementations are provided below.

[0027] Embodiment 1:

[0028] See also Figures 3 to 6Further, the control assembly includes an assembly column 8 fixedly mounted on the outer wall of the assembly plate 20, a driving column 7 is slidably mounted on the outer wall of the assembly column 8, a plurality of connecting rods 5 are hinged on the outer wall of the driving column 7, and the other ends of the plurality of connecting rods 5 are hinged on the outer wall of the riveting block 4. The assembly column 8 is fixedly mounted on the assembly plate 20, so that the entire control assembly can be stably fixed on the brake disc. At the same time, the driving column 7 is slidably mounted on the outer wall of the assembly column 8. This design enables the connecting rod 5 to drive the riveting block 4 to move. By adjusting the sliding position of the driving column 7 on the assembly column 8, the riveting block can be accurately controlled by the connecting rod 5. This flexibility and adjustability enables the control component to adapt to different brake disc sizes and shapes, as well as different locking or releasing requirements. In addition, multiple connecting rods 5 are hinged on the outer wall of the driving column 7, and the other ends of the multiple connecting rods 5 are hinged to the outer wall of the riveting block 4. This hinge method makes the connection between the connecting rod 5 and the riveting block 4 tight and stable. Through the hinge of the connecting rod 5, the control component can apply a stable force to the riveting block 4, so as to more stably fix the brake disc. This stability and reliability ensure that the control component will not loosen or fail during use, thereby improving the reliability and safety of the entire system.

[0029] See also Figure 3 Furthermore, the outer wall of the assembly plate 20 is provided with a plurality of slide grooves 6, and the riveting block 4 is limitedly slid on the inner wall of the slide groove 6. Through the cooperation between the riveting block 4 and the slide groove 6, the slide groove 6 provides a fixed track, so that the riveting block 4 can slide within the slide groove 6. This limited sliding design ensures that the connection between the riveting block 4 and the assembly plate 20 is tight and stable. No matter what working conditions, the riveting block 4 can maintain a fixed position without loosening or falling off. In addition, the design of the slide groove 6 enables the control component to adapt to assembly plates 20 of different sizes and shapes. No matter whether the outer wall of the assembly plate 20 is linear or curved, the slide groove 6 can provide a suitable limited sliding space to ensure that the riveting block 4 can slide stably in the slide groove 6. This adaptability and compatibility enables the control component to be used on different types of vehicles or mechanical equipment, improving its application range and flexibility.

[0030] See also Figure 3Furthermore, a plurality of grooves are provided on the inner wall of the brake disc, and a protrusion is provided on the outer wall of the bearing sleeve 2. The grooves and the protrusions can form a spline fit. In the present invention, the grooves and the protrusions form a foolproof mechanism. The provision of such a foolproof mechanism can prevent the incorrect installation of parts or assemblies. By providing special grooves or protrusions on the parts, only the correct position and direction can be installed. Since only the correct position and direction can be installed, the operator can more easily identify the correct assembly method, thereby reducing the possibility of assembly errors, and can increase the stability and reliability of the assembly. Correctly installed parts can be better fixed in position, reducing the risk of loosening or falling off, which helps to ensure the stability and reliability of the assembly during operation and reduce the risk of failure and maintenance.

[0031] Based on the first embodiment, two implementation schemes of the locking assembly are provided:

[0032] The first embodiment of the locking assembly:

[0033] See also Figure 5 Furthermore, a locking assembly is provided at the top of the assembly column 8. The locking assembly includes a thread at one end opened at the top of the assembly column 8, and a nut 10 is connected to the thread. In the present invention, the control assembly is locked by tightening the threaded component, which can provide a reliable fixing force. The thread locking can prevent the threaded component from loosening or falling off under vibration, impact or other external forces, and the thread locking is a simple and easy-to-use fixing method. The locking can be completed by tightening the threaded component without the use of special tools or equipment. At the same time, the thread locking can be used repeatedly. When the lock needs to be released, the locking state can be released by rotating the threaded component counterclockwise. This reusability makes the thread locking very convenient, and it can be assembled and disassembled as needed, which also improves the user experience.

[0034] The second embodiment of the locking assembly:

[0035] See also Figure 6Furthermore, the locking assembly includes a circular groove 15 provided on the outer wall of the assembly column 8, a first locking sleeve 12 is slidably installed on the outer wall of the assembly column 8, an L-shaped groove is provided on the outer wall of the first locking sleeve 12, a second locking sleeve 11 is slidably installed on the inner wall of the L-shaped groove, a circle of steel balls 13 is provided on the first locking sleeve 12, and a reset spring 14 is fixedly installed on the top of the first locking sleeve 12. In the locked state, the steel balls on the first locking sleeve 12 are inserted into the circular groove on the assembly column 8, and the second locking sleeve 11 is pushed into the L-shaped groove to lock the steel balls. The second locking sleeve 11 can also be locked by the L-shaped groove and the reset spring 14. The use of this locking assembly can be more convenient and quick to install and disassemble, and the reset spring 14 is used to provide a stable connection. This design can prevent the locking assembly from loosening or falling off during use, maintain a stable connection state, improve the user experience, and facilitate the operator.

[0036] Embodiment 2:

[0037] See also Figures 7 and 8 Further, the control assembly includes an assembly disk 17 rotatably mounted on the outer wall of the assembly column 8, the outer wall of the assembly disk 17 is provided with a plurality of limit slots 16 in a circumferential array, the outer wall of the riveting block 4 is fixedly provided with a linkage column 22, the linkage column 22 can slide on the inner wall of the limit slot 16, the outer wall of the assembly disk 17 is symmetrically provided with a handle 18, and it is locked by a locking assembly, when the bearing sleeve 2 and the brake disc need to be fixed, the assembly disk 17 is rotated by rotating the handle 18, due to the cooperation between the limit slot 16 on the outer wall of the assembly disk 17 and the linkage column 22 on the riveting block 4, when the assembly disk 17 rotates, the linkage column 22 slides on the inner wall of the limit slot 16, so that the riveting block 4 is displaced to achieve a locking effect, and the outer wall of the assembly disk 17 is provided with a handle 18, which facilitates the operator to control the assembly disk 17. Through the handle 18, the operator can easily rotate the assembly disk 17 to achieve precise control of the assembly column 8. This design makes the operation more convenient and comfortable, and the locking assembly is arranged in this way, which can provide greater stability. The shape of the iris can keep the mechanism in a relatively stable posture during the movement, reduce the interference of vibration and swing, and improve the stability of the mechanism.

[0038] Based on the second embodiment, a locking assembly implementation scheme is provided:

[0039] See also Figure 8Furthermore, the locking assembly includes a locking buckle 19, which is rotatably mounted on the top of the assembly column 8. A slot is provided on the outer wall of the assembly column 8. In the locked state, the locking buckle 19 can be engaged with the slot. The above-mentioned control assembly can be effectively fixed by the above-mentioned parts. The structural design of the locking buckle 19 and the assembly column 8 enables them to be tightly connected together in the locked state. The locking buckle 19 is rotatably mounted on the top of the assembly column 8. By engaging with the slot of the assembly column 8, the stability and reliability of the locking assembly are ensured. This locking mechanism can effectively prevent the assembly from accidentally falling off or loosening. Moreover, the structure of the locking buckle 19 and the assembly column 8 is relatively simple, easy to operate and install. The locking buckle 19 only needs to be rotatably mounted on the top of the assembly column 8 to achieve a locked state, and the locking buckle 19 is tightly connected with the slot and is not easy to loosen or fall off. This safe and reliable locking mechanism can effectively prevent the assembly column from accidentally moving or deforming during use, thereby improving the stability and safety of the assembly.

[0040] Working principle: When the connection structure between the brake disc and the wheel hub bearing of the front steering axle of the truck is used, the wheel hub bearing is inserted into the inner wall of the brake disc and aligned through the spline fit. Then the control component is driven to displace the riveting block. After it is displaced to the preset position, the locking mechanism is used to lock the control component to achieve fixation.

[0041] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural components recorded in the specification and the drawings can also be directly processed according to the existing technical common sense. At the same time, the connection method of each component adopts the mature conventional means in the prior art, and the machinery, parts and equipment all adopt the conventional models in the prior art, so no specific description will be given here.
