In addition, the technical features involved in the various embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
[0032] like Figure 1-4 As shown, the present invention provides a rim clamp for a four-wheel alignment system for automobiles, comprising a triangular claw 1, a positioning leg 2, a telescopic leg 3, a rim positioning member 4, and a protective rubber strip assembly. The triangular claw 1 is positioned at the center of the rim; the positioning leg 2 comprises a positioning rod 21, the center of which is fixedly connected to a set of corner tips of the triangular claw 1; the telescopic leg 7 is a telescopic rod, the two ends of which are respectively fixedly connected to the other two sets of corner tips of the triangular claw 1; the rim positioning member 4 is provided with four groups, which are respectively perpendicularly arranged at the two ends of the front side of the positioning leg 2 and the two ends of the front side of the telescopic leg 7, and comprise a fixed column 41, a T-shaped rod 42 fixedly arranged at the front end of the fixed column 41, and a rotating seat 43 rotatably arranged at the upper end of the T-shaped rod 42; the protective rubber strip assembly isolates and buffers the positioning leg 2, the telescopic leg 3, and the rim positioning member 4 from the rim to prevent damage to the rim paint surface. The rim clamp of the present invention is provided with a positioning leg member 2 to adjust the fulcrum of the clamping claw, thereby avoiding interference with the spokes and adding an extra fulcrum to make the clamp support more firm.
[0033] like Figure 1 and Figure 4 As shown, the triangular clamping claw 1 is a built-in mechanism of the four-wheel alignment system, and its center point is fixedly connected to the center of the rim for positioning support. The three groups of corner tips are respectively provided with a first positioning hole, a second positioning hole and a third positioning hole.
[0034] like Figure 2 As shown, the positioning leg member 2 is used to adjust the claw fulcrum and includes a positioning rod 21, a first fixing hole 22 provided in the middle of the positioning rod 21, and first connecting holes 23 provided at both ends of the positioning rod 21. The positioning rod 21 is adjusted in length according to the corresponding spoke model to avoid obstruction of the spokes at its two end fulcrums. The first fixing hole 22 is threadedly connected to a first bolt passing through the first positioning hole, thereby fixing the positioning rod 21 to the front side of the triangular claw 1. The first connecting hole 23 is used for fixed connection to the rim positioning member 4.
[0035] like Figure 3-4As shown, the telescopic leg member 3 includes a fixed rod 31, a sliding rod 32, a sliding hole 33, a round rod 34, a second fixing hole 35, and a second connecting hole 36. The fixed rod 31 has a sliding hole 33 at one end along its axis. The round rod 34 has an outer diameter that matches the inner diameter of the sliding hole 33 and slides within the sliding hole 33. The other end of the round rod 34 is fixedly connected to the sliding rod 32. The round rod 34 slides along the sliding hole 33, allowing the fixed rod 31 and the sliding rod 32 to move closer or further apart, thereby meeting the positioning requirements of different models of triangular claws 1. There are two sets of second fixing holes 35, one at the far end of the fixed rod 31 and the other at the far end of the sliding rod 32. Second bolts are threadedly connected to the two sets of second fixing holes 35 by passing through the second and third positioning holes of the triangular claw 1, thereby fixing the telescopic leg member 3 to the front side of the triangular claw 1. There are two sets of second connecting holes 36, each located above the second fixing holes 35, for connecting and fixing the wheel rim positioning member 4.
[0036] The wheel rim positioning member 4 includes a fixing column 41, a T-shaped rod 42 fixedly arranged at the front end of the fixing column 41, and a rotating seat 43 rotatably arranged at the upper end of the T-shaped rod 42; wherein, the rear end of the fixing column 4 is provided with a threaded portion, through which the fixing column 4 is threadedly connected to the first connecting hole 23 and the second connecting hole 36 respectively; the T-shaped rod 42 is threadedly connected to the front end of the fixing column 4, and limits the rotating seat 43 through a T-shaped structure to prevent it from falling off; the rotating seat 43 is a U-shaped member, and a rotating hole is provided on both sides of it, through which the T-shaped rod 42 is passed to realize a rotating connection with the T-shaped rod 42, and its bottom is an arc-shaped plate, which is adapted to the rim and fits on the inner ring of the rim, thereby supporting and positioning.
[0037] The protective rubber strip group includes a first protective rubber strip 5, a second protective rubber strip 6 and a third protective rubber strip 7; wherein, the first protective rubber strip 5 is fixedly arranged on the front side of the positioning leg member 2, and its front side is in contact with the wheel spoke; the second protective rubber strip 6 is fixedly arranged on the front side of the telescopic leg member 3, and its front side is in contact with the wheel spoke; the third protective rubber strip 7 is fixedly arranged on the bottom of the arc-shaped plate of the rotating seat 43, and its outer side is in contact with the inner ring of the rim, thereby increasing the friction between the rim positioning member 4 and the inner ring of the rim while protecting the paint surface, thereby enhancing the clamping force of the fixture.
[0038] When the rim clamp of the present invention is in operation, the triangular clamping jaw 1 is moved to align it with the rim; the triangular clamping jaw 1 is rotated to align the rim positioning members 4 at both ends of the telescopic support leg member 3 with the gap between the spokes; the triangular clamping jaw 1 is fine-tuned to align the rim positioning members 4 at both ends of the positioning support leg member 2 with the gap between the spokes; after ensuring that the four groups of rim positioning members 4 can all pass through the gap between the spokes, the center point of the triangular clamping jaw 1 is fixedly connected to the center of the rim for positioning and support. At this time, the first protective rubber strip 5 and the second protective rubber strip 6 respectively separate the positioning support leg member 2 and the telescopic support leg member 3 from the spoke to avoid damage to the paint surface; the rotating seat 43 is rotated to support and fix the third protective rubber strip 7 at the bottom to the inner ring of the rim, thereby completing the locking and positioning of the clamp on the tire.
[0039] The rim clamp of the present invention is provided with a positioning leg member 2 on the basis of the original triangular clamping claw 1, and its original clamping claw fulcrum is changed to the two ends of the positioning leg member 2, thereby avoiding interference with the spokes, so that the rim positioning member 4 can smoothly pass through the spokes to support and lock the inner ring of the rim. At the same time, an additional fulcrum is added to make the clamp support more firm.
[0040] The rim clamp of the present invention is provided with a positioning support leg part 2 to change the position of the claw fulcrum, and is provided with a telescopic support leg part 3 to adjust its own length to adapt to various types of triangular claws 1, so that the clamp can be applied to various types of automobile four-wheel alignment systems and can clamp and position rims with various spoke spacings. It does not require the original triangular claws 1 to be modified, which greatly saves the cost of replacing or modifying the automobile four-wheel alignment system and has high promotion value.
[0041] The rim clamp of the present invention is provided with a first protective rubber strip 5, a second protective rubber strip 6 and a third protective rubber strip 7, which can isolate and buffer the clamp from the rim to avoid damage to the rim paint surface, while increasing the friction between the rim positioning part 4 and the inner ring of the rim, thereby enhancing the clamping force of the clamp.
[0042] It is easy for those skilled in the art to understand that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
