Description

Technical Field

[0001] This utility model belongs to the field of automotive maintenance technology, specifically relating to a quick-installation structure for brake discs. Background Technology

[0002] The brake disc is a key component of a car's braking system. It is typically a round disc that rotates along with the wheels when the vehicle is in motion. Its main function is to generate braking force, in conjunction with the brake calipers, to slow the vehicle down or bring it to a stop. When the driver presses the brake pedal, the brake calipers clamp the brake disc, and the friction between the brake pads and the brake disc achieves the braking effect.

[0003] In terms of performance, brake discs need to possess sufficient hardness and wear resistance to withstand high temperatures and pressures, while maintaining good frictional properties to ensure stable operation during emergency braking or prolonged braking. However, brake discs will also wear down due to factors such as driving habits, vehicle load, brake pad material, and road conditions. Common signs of wear include reduced brake disc thickness, surface cracks or deformation, and increased braking distance, in which case the brake discs need to be replaced promptly.

[0004] When replacing brake discs, the nuts used on the upper part of the brake disc are located inside the wheel, which makes it inconvenient to remove and install the brake disc, especially when the vehicle cannot be lifted. It is extremely time-consuming and laborious for technicians to remove the nuts inside the wheel. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a quick-installation structure for brake discs.

[0006] The technical solution adopted to solve the above technical problem is: a brake disc quick-installation structure, including a base, an electric cylinder mounted on the top of the base, a tray mounted on the top of the electric cylinder, a fixing ring mounted on one side of the top of the tray, an installation block slidably mounted on the back of the fixing ring, a first assembly plate mounted on the top of the installation block, an installation plate rotatably mounted on the end of the first assembly plate away from the fixing ring, a bracket mounted on the side of the installation plate, an assembly box mounted on one end of the bracket, a gear set rotatably mounted on the inside of the assembly box, a gear ring rotatably mounted inside the assembly box, a first motor mounted on the side of the bracket, a second assembly plate slidably mounted inside the installation block, a second motor mounted on the bottom side of the second assembly plate, and the output end of the second motor passing through the second assembly plate and mounted with a hexagonal cylinder.

[0007] Furthermore, at least one gear in the gear set meshes with the gear ring, and the output end of the first motor extends into the assembly box and connects with the gear located at the top of the gear set. Through the above arrangement, the gear ring is driven to rotate by the motor through the meshing action of the gear and the gear ring.

[0008] Furthermore, the side of the assembly box has a through hole that matches the inner ring of the gear ring. A nut is installed inside the gear ring, allowing the nut inside the gear ring to fit onto the nut used on the front of the car plate, thus acting as a wrench.

[0009] Furthermore, the top of the tray is arc-shaped, and the bottom surface of the mounting plate has a through hole facing the center of the gear ring. The through hole allows the screw used to install the brake disc on the front of the tire to pass through without interfering with the installation and removal.

[0010] Furthermore, the top of the second assembly plate is T-shaped, and the interior of the mounting block has a sliding groove that matches the top of the second assembly plate. Through the above structural design, the second assembly plate can slide smoothly.

[0011] Furthermore, the side of the fixing ring is provided with an annular groove that matches the mounting block, and the contact surface between the mounting block and the annular groove inside the fixing ring is provided with a friction layer. The friction layer is provided to stabilize the position of the mounting block after it moves.

[0012] The beneficial effects of this utility model are as follows: This utility model improves installation efficiency by using the components mounted on the mounting plate to assemble and disassemble the nuts on the front side of the brake disc and on the second mounting plate to assemble and disassemble the nuts on the inner side of the brake disc. Through motor drive and a reasonable mechanical structure design, the installation of the brake disc can be completed quickly and accurately, reducing manual operation time and labor intensity. Furthermore, it improves installation quality. Precise gear transmission and a stable sliding structure ensure the stability and accuracy of the installation process, making the brake disc installation more secure and reliable. In addition, the design of this structure has a certain degree of flexibility; the rotatable design of the mounting plate and the sliding design of the second mounting plate can adapt to the assembly and disassembly of nuts in different installation positions, exhibiting strong versatility.

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0019] like Figures 1 to 4 As shown, this embodiment involves a quick-installation structure for brake discs, including a base 1. The base 1 serves as the fundamental support for the entire structure, playing a crucial role in stabilizing the entire device during installation. In actual working environments, various vibrations and shaking may occur; this ensures the entire structure does not shift or shake due to external interference. An electric cylinder 2 is installed on top of the base 1. The electric cylinder 2 is an electrically driven device that can precisely control vertical displacement. Its working principle is to convert electrical energy into mechanical energy, achieving extension and retraction through an internal transmission mechanism. Due to its electric drive, it can achieve relatively precise extension and retraction, adjusting height to the millimeter level, and is adaptable to brake discs of different sizes. A tray 3 is installed on top of the electric cylinder 2. The top of the tray 3 is curved, as brake discs typically have a certain curvature; the curved tray better adapts to the shape of the brake disc, providing better support.

[0020] like Figure 1 As shown, a fixing ring 4 is installed on one side of the top of the tray 3. The side of the fixing ring 4 has an annular groove that matches the mounting block 5. A friction layer is provided on the contact surface between the mounting block 5 and the annular groove inside the fixing ring 4. This friction layer is made of wear-resistant material and its function is to increase friction. During the sliding process of the mounting block 5, the friction allows the mounting block 5 to better control its position, preventing it from sliding randomly due to vibrations or other factors during installation. A first mounting plate 6 is installed on the top of the mounting block 5. A mounting plate 7 is rotatably mounted on the end of the first mounting plate 6 away from the fixing ring 4, fixedly around its axis. The mounting plate 7 can rotate around its fixed axis. In actual brake disc installation, different installation scenarios and brake disc specifications may vary. The rotation function of the mounting plate 7 allows for easy adjustment of the angle to adapt to different installation requirements. A bracket 8 is installed on the side of the mounting plate 7, serving as a connection and support. An assembly box 9 is installed at one end of the bracket 8.

[0021] like Figure 3 As shown, a gear set 10 is rotatably mounted on a fixed axis inside the assembly box 9. At least one gear in the gear set 10 meshes with a gear ring 11. The output end of the first motor 12 extends into the assembly box 9 and connects to the upper gear in the gear set 10. When the first motor 12 starts, the rotor inside the motor begins to rotate, transmitting power to the gear set 10 through the output shaft, thereby driving the gear set 10 to rotate. Since the gear set 10 meshes with the gear ring 11, it drives the gear ring 11 to rotate. A through hole matching the inner ring of the gear ring 11 is provided on the side of the assembly box 9, and a nut is installed inside the gear ring 11. When installing the brake disc, the nut is fitted with the nut used on the front of the brake disc, which acts like a wrench, ensuring quick installation and removal of the nut used on the front of the brake disc.

[0022] like Figure 3 As shown, a first motor 12 is mounted on the side of the bracket 8, and a second mounting plate 13 is slidably mounted inside the mounting block 5. The top of the second mounting plate 13 is T-shaped, and a groove adapted to the top of the second mounting plate 13 is formed inside the mounting block 5. This unique structure allows the second mounting plate 13 to slide stably inside the mounting block 5. A second motor 14 is mounted on the bottom side of the second mounting plate 13, and the output end of the second motor 14 passes through the second mounting plate 13 and is fitted with a hexagonal cylinder 15.

[0023] The working principle of this quick-installation brake disc structure is as follows: First, after the brake disc is installed on the tire, the height of the tray 3 is adjusted by the electric cylinder 2 during the subsequent tightening of the nuts. The operator can precisely adjust the height by controlling the electric cylinder 2 according to the actual installation requirements, ensuring the brake disc reaches the appropriate height so that it fully fits against the curved surface of the tray, with the tray 3 supporting the bottom of the brake disc. Next, the gear ring 11 is fitted onto the front nut of the brake disc, and the first motor 12 is started. The first motor 12 drives the gear set 10 to rotate. Since the gear set 10 meshes with the gear ring 11, it drives the gear ring 11 to rotate, causing the nut inside the gear ring 11 to rotate as well, achieving initial tightening of the front nut of the brake disc. Simultaneously, the mounting plate 7 can rotate around a fixed axis. The operator can flexibly adjust the angle of the mounting plate 7 according to the specific installation requirements of the brake disc to adapt to different installation needs.

[0024] During the installation of the nuts located on the inside of the tire, the second motor 14 starts, and the rotation of the motor is transmitted to the hexagonal cylinder 15 through the output shaft, causing the hexagonal cylinder 15 to rotate. The hexagonal cylinder 15 can mate with the bolts on the brake disc to further complete the installation of the brake disc. The second mounting plate 13 slides inside the mounting block 5, and the operator can flexibly adjust the position of the second mounting plate 13 according to the position of the bolts to ensure that the hexagonal cylinder 15 is accurately aligned with the bolts.

[0025] This improves installation and disassembly efficiency through the aforementioned principles. Driven by a motor and featuring a well-designed mechanical structure, the entire installation process is automated and semi-automated, enabling rapid and accurate brake disc installation while reducing manual operation time and labor intensity. Compared to traditional brake disc installation methods that require multiple workers and significant time, this structure allows a single worker to easily complete the installation, greatly saving manpower and time costs. Furthermore, it improves installation quality. Precise gear transmission and a stable sliding structure ensure the stability and accuracy of the installation process. During gear transmission, the dimensions and tooth profile of each gear are precisely designed and machined, enabling precise power transmission and motion control, resulting in a more secure and reliable brake disc installation. In addition, the structure offers flexibility; the rotatable design of mounting plate 7 and the sliding design of the second mounting plate 13 allow for adaptation to brake discs of different specifications and installation requirements, demonstrating strong versatility. Whether for brake discs on small mechanical equipment or large industrial equipment, this structure leverages its advantages to achieve efficient and high-quality installation.

[0026] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model.
