Description

Technical Field

[0001] The utility model relates to a clamp for an automobile stabilizer bar. Background Art

[0002] The stabilizer bar assembly is a crucial component of the vehicle chassis, typically mounted on the subframe or mainframe. It plays a crucial role in ensuring the vehicle's lateral stability during driving. The stabilizer bar assembly connects to other chassis components via clamps and the stabilizer bar end. The stabilizer bar assembly features two sets of clamps (a first clamp and a second clamp), each consisting of an upper clamp and a lower clamp. These clamps are riveted together using a mold to secure the rubber bushing that fits over the stabilizer bar.

[0003] Typically, vehicle manufacturers have strict assembly order requirements for stabilizer bar clamps, requiring the base hole to be installed first, followed by the remaining three holes. Consequently, the mounting holes for stabilizer bar clamps have specific diameters. In actual production, since the first and second clamps have identical appearances and the diameter difference between the mounting holes is only about 1mm, making it difficult to distinguish visually, clamp assembly errors are common. For example, the lower clamp of the second clamp must be assembled with the upper clamp of the first clamp, or the mounting holes of the same clamp must be installed in the wrong direction. Summary of the Invention

[0004] The technical problem to be solved by the utility model is to provide a clamp assembly for an automobile stabilizer bar, which can prevent the clamp assembly from being misassembled during the assembly process and can improve the assembly efficiency.

[0005] The clamp assembly of a vehicle stabilizer bar according to an embodiment of the utility model includes a first clamp and a second clamp, the first clamp including a first upper clamp and a first lower clamp, and the second clamp including a second upper clamp and a second lower clamp; the first lower clamp and the second lower clamp are both flat-plate-shaped, and each lower clamp is respectively provided with a lower clamp mounting hole near both ends; the first upper clamp and the second upper clamp each include a clamp body and a pair of clamp ears, the clamp body is in an inverted U-shape, the pair of clamp ears are respectively connected to two sides of the clamp body, and each clamp ear is provided with an upper clamp mounting hole; the outer contour line of the first upper clamp is projected on the first lower clamp to coincide with the outer contour line of the first lower clamp, and the outer contour line of the second upper clamp is projected on the second lower clamp to coincide with the outer contour line of the second lower clamp; the outer contour line of the first lower clamp is waist-shaped, consisting of two parallel opposite straight line segments and two open opposite circular arc segments, one of which is provided with a first anti-error notch; the outer contour line of the second lower clamp is rectangular, one corner of the rectangle is provided with a second anti-error notch, and the remaining three corners of the rectangle are provided with chamfers.

[0006] The utility model has at least the following advantages:

[0007] 1. After adopting the above technical solution, even with the naked eye, it is easy to distinguish the difference between the first clamp and the second clamp and the difference in the mounting holes on each clamp, thereby reducing the probability of the clamp being installed incorrectly;

[0008] 2. Simply make the shape of the cavity of the clamp assembly mold coincide with the outer contour of the corresponding clamp to prevent the clamp from being misplaced, thereby preventing the clamp assembly from being misassembled during the assembly process, avoiding rework and reassembly, and improving assembly efficiency.

[0011] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0012] Please refer to Figures 1 to 6 As shown in the figure, the clamp assembly of the automobile stabilizer bar according to the embodiment of the present utility model includes a first clamp 1 and a second clamp 2.

[0013] The first clamp 1 includes a first upper clamp 1 a and a first lower clamp 1 b , and the second clamp 2 includes a second upper clamp 2 a and a second lower clamp 2 b .

[0014] Both the first lower clamp 1b and the second lower clamp 2b are flat. The first lower clamp 1b has a waist-shaped outer contour, consisting of two parallel, opposing straight segments 11 and two open, opposing circular arc segments 12. One of the circular arc segments 12 has a first error-proofing notch 121. The second lower clamp 2b has a rectangular outer contour, with a second error-proofing notch 221 at one corner and chamfers 222 at the remaining three corners. In this embodiment, the edges of the first error-proofing notch 121 and the second error-proofing notch 221 are curved.

[0015] The first lower clamp 1b is provided with a lower clamp mounting hole 131b and a lower clamp mounting hole 132b near both ends; the second lower clamp 2b is provided with a lower clamp mounting hole 231b and a lower clamp mounting hole 232b near both ends.

[0016] The first upper clamp 1a includes a first clamp body 13a and a pair of first clamp ears 14a. The first clamp body 13a is in an inverted U-shape. The pair of clamp ears 14a are respectively connected to the two sides of the first clamp body 13a. The pair of first clamp ears 14a respectively define an upper clamp mounting hole 141a and an upper clamp mounting hole 142a. The projection of the outer contour of the first upper clamp 1a on the first lower clamp 1b coincides with the outer contour of the first lower clamp 1b.

[0017] The second upper clamp 2a includes a second clamp body 23a and a pair of second clamp ears 24a. The second clamp body 23a is in an inverted U-shape. The pair of second clamp ears 24a are respectively connected to the second clamp body 23a on either side. The pair of second clamp ears 24a respectively define an upper clamp mounting hole 241a and an upper clamp mounting hole 242a. The projection of the outer contour of the second upper clamp 2a onto the second lower clamp 2b coincides with the outer contour of the second lower clamp 2b.

[0018] Because the first and second clamps 1 and 2 have distinct appearances, they can be easily distinguished by the naked eye, reducing the chance of mis-installation. The waist-shaped outer contour of the first clamp 1 and the chamfered rectangular outer contour of the second clamp 2 prevent injuries from sharp corners and improve safety. Each clamp has two mounting holes, one near the notch and the other away, making them easily distinguishable to the naked eye, thus reducing the chance of mis-installation.

[0019] During assembly, the first upper clamp 1a and the first lower clamp 1b, as well as the second upper clamp 2a and the second lower clamp 2b, are connected together by riveting. The first upper clamp 1a, the second upper clamp 2a, the first lower clamp 1b, and the second lower clamp 2b are each placed in the corresponding mold cavities. The shapes of the mold cavities match the shapes of the corresponding clamps. If the clamps are placed incorrectly, they will not fit into the corresponding cavities. For example, the mold cavity for the first lower clamp 1b has a shape that matches the outer contour of the first lower clamp 1b, and a first anti-error protrusion is located at a position corresponding to the first anti-error notch 121. When a second lower clamp 2b with a completely different shape is placed, interference occurs, preventing the second lower clamp 2b from being placed, thereby preventing the second lower clamp 2b from being incorrectly assembled with the first upper clamp 1a. If the two mounting holes of the first lower clamp 1b (i.e., the lower clamp mounting hole 131b and the lower clamp mounting hole 132b) are installed upside down, the first lower clamp 1b will be unable to be placed in the mold cavity due to interference from the first anti-error protrusion.

[0020] In this embodiment, the bottom surface of the hoop ear of each upper clamp is provided with a downward extending riveting protrusion 15a at the periphery of the upper clamp mounting hole. The riveting protrusion 15a extends into the lower clamp mounting hole of the corresponding lower clamp for riveting.

[0021] The utility model can prevent the clamp assembly from being incorrectly installed during the assembly process, avoids rework and reassembly, and improves the assembly efficiency of the clamp assembly.

[0022] The above description is a further explanation of the present invention in conjunction with specific embodiments and the accompanying drawings. However, the present invention can obviously be implemented in a variety of other ways than those described herein, and those skilled in the art can generalize and deduce them based on actual usage without violating the scope of the present invention. Therefore, the content of the above specific embodiments should not limit the scope of protection of the present invention.
