Problems solved by technology

However, this requires vulcanization molding of the bushing to be performed with a bulky and heavy stabilizer bar set directly in the mold for the rubber bushing, leading to a problem of considerably high equipment cost due to large-scale equipment

Embodiment Construction

[0020] The present invention will be described in further detail below in conjunction with specific embodiments.

[0021] A bonding technology for automobile stabilizer bar and stabilizer bushing, the stabilizer bar is a torsion bar spring made of spring steel, such as 50CrVA, 60Si 2 MnA, 60Si 2 Mn, etc.; the stabilizer bar bushing is a rubber part, and the adhesive is coated between the horizontal stabilizer bar and the stabilizer bar bushing and vulcanized into one.

[0022] The bonding steps are as follows:

[0023] S1. The forming of the transverse stabilizer bar and the forming of the bushing of the stabilizer bar;

[0024] The transverse stabilizer bar adopts intermediate frequency induction, and the spring steel that is rapidly heated to 700°C-723°C for intermediate temperature rolling can have the advantages of both cold deformation and hot deformation, avoiding the disadvantages of cold and hot deformation. The use of medium temperature rolling makes the material h...

Abstract

The invention provides an adhesion technology for a transverse stabilizer bar and a stabilizer bar bushing of an automobile. The adhesion technology comprises the steps that 1, the transverse stabilizer bar is subjected to medium-frequency induction and moderate temperature rolling molding, and the stabilizer bar bushing is subjected to hot runner injection molding; 2, the inner surface of the stabilizer bar bushing is coated with adhesives with uniform thickness and dried in the air; 3, the bushing coated with the adhesives in the step 2 is subjected to vulcanization treatment, and a pre-vulcanized bushing is obtained; 4, the surface of the stabilizer bar is subjected to sand blasting treatment, and the pre-vulcanized rubber bushing obtained in the step 3 adheres to the surface of the stabilizer bar; and 5, compressing force is uniformly applied to the bushing in the direction perpendicular to the axis of the stabilizer bar. According to the adhesion technology, the operation steps are simple, the cost is low, the adhesion quality can be ensured, and abrasion and abnormal sound between the stabilizer bar and the bushing are effectively relieved.

Description

technical field [0001] The invention relates to the technical field of an automobile lateral stabilizer bar, in particular to a bonding technology of an automobile lateral stabilizer bar and a stabilizer bar bushing. Background technique [0002] Automobile stabilizer bar is an auxiliary elastic element in the automobile suspension. Its function is to prevent the body from excessive lateral roll when turning, and to keep the body as balanced as possible. The stabilizer bar bushing is fixed on the vehicle frame and plays a role in supporting and positioning the stabilizer bar. At the same time, the stabilizer bar bushing must have sufficient axial stiffness to limit the axial play of the stabilizer bar. In the prior art, metal clips are used to fix the stabilizer bar and the stabilizer bar bushing, and there will be abnormal noises between the stabilizer bar and the stabilizer bar during driving, especially at low temperature due to the rubber of the stabilizer bar bushing. ...
