Description

Technical Field

[0001] This utility model relates to the field of automotive technology, and in particular to a wheel removal and installation tool. Background Technology

[0002] Vehicle reliability testing is an indispensable part of automotive research and development, revealing design and manufacturing problems in vehicles and their components. Reliability testing typically involves various road surface tests, including high-speed circuits, uneven roads, mountain highways, and off-road tracks. Due to the extremely harsh conditions of uneven roads and off-road tracks, tire wear is very high. To ensure the safety of test personnel, wheels must be removed and tires replaced when the tire tread reaches its limit. A single reliability test usually requires multiple wheel removals and reassemblies. Currently, most wheel removal methods involve two people working together to remove and reassemble the wheel from the vehicle's brake disc assembly using tools such as pry bars. This method is not only time-consuming and labor-intensive but also inherently dangerous.

[0003] An existing patent discloses a tire changer (CN210337475U), which combines roller movement and fork lifting in traditional tire removal work, effectively utilizing the lever principle to reduce the labor intensity of disassembly and replacement maintenance personnel. However, the wheels are prone to tipping over during tire removal and installation, leading to safety accidents. Furthermore, the operation requires bending over, which is strenuous; it also requires two people to work together, resulting in significant manpower consumption. In addition, when performing tire removal and installation work, due to the differences in tread blocks, weight, and size between commercial vehicle tires and off-road vehicle tires, there is a risk that the tire changer may not be able to support the wheel, potentially causing it to tip over, posing a significant danger.

[0041] Example 1

[0042] See Figure 1-4 As shown, the wheel removal and installation tool provided in this application embodiment includes:

[0043] Connector;

[0044] The wheel bearing part is located at the first end of the connecting frame. The bottom of the wheel bearing part is provided with a roller assembly, and the upper part of the wheel bearing part is provided with a support frame 8.

[0045] The pressing part is located at the second end of the connecting frame.

[0046] The connecting frame has a wheel bearing part and a pressing part installed at both ends. After removing the wheel fixing bolts, the user can press the pressing part to make the wheel bearing part tilt upward. The wheel bearing part supports the wheel and moves the wheel away from the car through the roller assembly. The support frame 8 ensures that the wheel can lean against the support frame 8 when it tilts during the movement, thus avoiding the safety accident caused by the wheel tilting.

[0047] See Figure 1-4 As shown, the connecting frame includes at least two longitudinal bars 1 and several connecting beams 2 arranged between adjacent longitudinal bars 1. The first end of the longitudinal bar 1 is connected to a wheel bearing part, and the second end is connected to a pressing part.

[0048] In this embodiment, there are two longitudinal rods 1, connected by three connecting beams 2. The three connecting beams 2 are arranged at equal intervals and are perpendicular to the longitudinal rods 1. Each longitudinal rod 1 is connected to the wheel bearing part and the pressure part at both ends, respectively.

[0049] See Figure 1-4 As shown, the wheel-bearing part includes:

[0050] Fork 6, the first end of fork 6 is connected to the first end of longitudinal bar 1, a roller assembly is provided at the bottom of fork 6, and a support frame 8 is provided at the top of fork 6;

[0051] Clamp 7 is located at the second end of the fork 6.

[0052] In this embodiment, two forks 6 are provided, each welded to the first end of one of the two longitudinal bars 1. A clamp 7 is bolted to the second end of the fork 6. A support frame 8 is welded to the middle of the fork 6 and close to the connecting frame. The support frame 8 includes two support rods, with a connecting beam 2 connecting the two support rods to prevent tipping. The fork 6 is tilted upwards, and the clamp 7 supports the bottom of the wheel to allow the wheel to move via the roller assembly. The angle between the two forks 6 is 30-45 degrees, making it easier to insert them into the bottom of the wheel to support it, and reducing limitations compared to the parallel forks 6 in the prior art.

[0053] See Figure 1-3 As shown, the roller assembly includes:

[0054] Roller connecting rod 5, the middle part of which is fixed to the bottom of fork 6;

[0055] Roller 4 is installed at both ends of roller connecting rod 5.

[0056] In this embodiment, two rollers 4 are respectively installed at both ends of the roller connecting rod 5. The roller connecting rod 5 is also welded to the bottom of the two forks 6. The roller connecting rod 5 can strengthen the structural strength of the forks 6, bear a greater weight than the prior art, can be used in harsh working conditions, and is not easily damaged.

[0057] See Figure 1-4 As shown, the pressing part includes:

[0058] Foot pedal connecting rod 12, with both ends of the foot pedal connecting rod 12 rotatably connected to the first ends of two adjacent vertical rods 1;

[0059] Foot pedal 11 is installed in the middle of foot pedal connecting rod 12.

[0060] Using a foot pedal 11, with both ends of the foot pedal connecting rod 12 rotatably connected to the first ends of the two longitudinal rods 1, the foot pedal 11 rotates when pressed down during disassembly and assembly, allowing for smooth pedaling by the operator. A limiting component can be designed along the rotation path of the foot pedal 11 and installed on the longitudinal rods 1; typically, the maximum rotation angle of the foot pedal 11 in both directions is set to 30 degrees. This foot pedal design avoids the operator bending over, allowing only one person to complete wheel disassembly and assembly using leg strength, reducing labor costs and saving time.

[0061] See Figure 1-4 As shown, the upper surface of the foot pedal 11 is provided with anti-slip ridges.

[0062] The anti-slip ridges increase the friction between the foot pedal 11 and the operator's shoe sole, ensuring that the operator is less likely to slip during operation and reducing operational risks.

[0063] See Figure 1-4 As shown, the pressing part also includes a foot pedal limiting pin 13, which is inserted into both the first end of the longitudinal rod 1 and the foot pedal connecting rod 12.

[0064] The travel of the foot pedal 11 is limited by a limit pin, providing stable support during wheel movement.

[0065] See Figure 1-2 As shown, the connecting frame and the wheel bearing part are connected by a curved beam 3, and the support frame 8 is set between the roller assembly and the curved beam 3. The included angle between the connecting frame and the wheel bearing part is 120-160 degrees.

[0066] The connection between the connecting frame and the wheel bearing unit via the curved beam 3 is more robust. When the angle between the connecting frame and the wheel bearing unit is 160 degrees, the angle is relatively large, and the lever principle can easily pull away wheels of any weight. The support frame 8 is set between the roller assembly and the curved beam 3, ensuring that the overall center of gravity does not shift significantly when the wheel rests on the support frame 8, making the wheel movement more stable.

[0067] Furthermore, the clamp 7 can be replaced at any time according to the wheel width, making it suitable for changing wheels of different sizes, so that the clamp 7 can precisely clamp the two sides of the vehicle wheel, saving time and effort and increasing disassembly and assembly efficiency.

[0068] The usage process of this utility model is as follows:

[0069] When removing a wheel, use a jack to lift the side of the vehicle body where the wheel needs to be removed or installed, maintaining a gap of about 10 cm between the wheel and the ground. Use a special tool to remove all the fixing bolts between the vehicle's brake disc assembly and the wheel. Insert the clamp 7 through the gap between the wheel and the ground into the bottom of the wheel, pressing it firmly against the inner and outer sides of the wheel. The operator steps on the foot pedal 11, causing the fork 6 to tilt upwards. The clamp 7 supports the tire. Use the roller assembly to move the wheel away from the vehicle. After the wheel is completely separated from the vehicle's brake disc assembly, the operator can lean the wheel against the support frame 8. The support frame 8 ensures that the wheel can lean against the support frame 8 if it tipes over during movement, preventing accidents caused by the wheel tipping over. When installing the wheel, place the wheel on the clamp 7 and use the roller assembly to move the wheel closer to the vehicle. When it reaches the vicinity of the vehicle's brake disc assembly, the operator steps on the foot pedal 11 to stop the wheel at the required height, and then uses bolts to install the wheel onto the vehicle's brake disc assembly.

[0070] This tool allows one person to easily disassemble and assemble wheels, greatly improving work efficiency and saving time and effort. The support frame effectively prevents the wheels from tipping over and causing safety accidents during disassembly and assembly. This tool is suitable for various vehicle types, such as commercial vehicles, passenger cars, off-road vehicles, and special-purpose vehicles.
