Problems solved by technology

The stabilizer bar sleeve and the fastened contact part of the rear axle are generally connected by two connection methods, one connection method is plane connection, such as image 3 As shown, once this kind of structure is loose, when passing a bumpy road or turning quickly, the line change will produce abnormal noise, which will cause a lot of after-sales complaints. The other is a sawtooth surface connection, such as Figure 4 As shown, the sawtooth of this structure will damage the contact surface of the rear axle and cause corrosion when the car is running. The corrosion loss caused by long-term use will cause the torque of the connection part to decrease, which will not only reduce the driving quality, but also cause looseness and abnormal noise.

Embodiment 1

[0038] Such as figure 1 with figure 2 As shown, the rear axle stabilizer bar 2 in the prior art is generally connected to the rear axle through fasteners 3 . The fastening contact between the stabilizer bar sleeve 4 and the rear axle 1 is usually connected by two connection methods, one connection method is plane connection, such as image 3 As shown, once this kind of structure is loose, when passing a bumpy road or turning quickly, the line change will produce abnormal noise, causing great after-sales complaints; the other is a sawtooth surface connection, such as Figure 4 As shown, the sawtooth of this kind of structure will damage the contact surface of the rear axle 1 and cause corrosion when the car is running. Cause loose noise.

[0039] In view of the above problems, this embodiment provides a rear axle stabilizer bar anti-loosening and anti-abnormal noise structure, including a rear axle stabilizer bar 2, and the rear axle stabilizer bar 2 is fixed on the rear ax...

Embodiment 2

[0045] This embodiment provides a rear axle stabilizer bar anti-loosening and anti-abnormal noise structure, including a rear axle stabilizer bar 2, and the rear axle stabilizer bar 2 is fixed on the rear axle by fasteners 3, such as figure 1 with figure 2 shown. Both ends of the rear axle stabilizer bar 2 are respectively provided with a stabilizer bar sleeve 4, and the stabilizer bar sleeve 4 is welded to the surface of the rear axle stabilizer bar 2 along the welding seam 5, as Figure 5 shown. The material of the stabilizer sleeve 4 has a wide range of sources, low carbon steel and alloy steel can be used, and the cost is low.

[0046] Such as Figure 5 As shown, the stabilizer bar sleeve 4 has a tube top surface 6 and a tube bottom surface 7 , and the tube top surface 6 is the contact surface between the stabilizer bar sleeve 4 and the rear axle 1 . The cylinder top surface 6 is processed into a first circular ring plane 61 and a second circular ring plane 62 with an...

Abstract

The invention discloses a structure for preventing a rear axle stabilizer rod from loosening and having abnormal sound. The structure comprises a rear axle stabilizer rod, wherein stabilizer rod sleeve barrels are respectively and fixedly connected to two ends of the rear axle stabilizer rod; each stabilizer rod sleeve barrel is provided with a barrel top surface and a barrel bottom surface; eachbarrel top surface comprises a first annular plane and a second annular plane; the height between each second annular plane and the corresponding barrel bottom surface is greater than that between thecorresponding first annular plane and the corresponding barrel bottom surface; loosening preventing teeth are arranged on each first annular plane, and each loosening preventing tooth is provided with a tooth top and a tooth root; and the height between each tooth top and the corresponding tooth root is greater than that between each first annular plane and the corresponding second annular plane.The structure disclosed by the invention is simple in structure, low in cost, and high in reliability; the problems that the torque of a relevant part is loosened, and a chassis at the relevant parthas abnormal sound can be solved; and the driving quality and the appearance quality can be improved.

Description

technical field [0001] The invention relates to the technical field of automobile rear axle assembly, in particular to a rear axle stabilizer bar anti-loosening and anti-abnormal noise structure. Background technique [0002] The rear axle is an extremely important component of the automobile chassis. It needs to bear the impact load and vibration from the road during the driving process. Therefore, the stiffness, strength, and fatigue life of the rear axle play an important role in the safety and comfort of the vehicle. to a vital role. [0003] The problems existing in the rear axle are mainly reflected in the stabilizer bar. In the prior art, the rear axle stabilizer bar is connected to the rear axle by fasteners, such as figure 1 with figure 2 shown. The stabilizer bar sleeve and the fastened contact part of the rear axle are generally connected by two connection methods, one connection method is plane connection, such as image 3 As shown, once this kind of struct...
