Problems solved by technology
[0002] Recently, most of the bushings adopt the inner and outer two-layer skeleton structure, and rubber is filled between the two skeletons. The inner and outer skeletons are made of metal, and are an integral structure. When assembling, the accuracy of the outer diameter of the outer skeleton is used to ensure its tightness. , Due to various errors, it is easy to cause loose or too tight and deformed image, and the rubber clamped between the inner skeleton is limited, resulting in poor flexibility, poor cushioning, and unsatisfactory noise reduction and shock absorption effects; the rubber at both ends of the bush is exposed, Easy to cause damage, accelerate the amount of rubber wear and shorten the service life of the bushing

The technical scheme includes that the split bushing assembly for the automotive suspension comprises an inner shaft, a rubber split bushing and ring sleeves, the rubber split bushing is sleeved on the inner shaft, the ring sleeves are arranged at two ends of the inner shaft, the rubber split bushing comprises an outer sleeve, an intermediate sleeve and an inner sleeve which are sleeved in sequence, rubber layers are arranged between the outer sleeve and the intermediate sleeve and between the intermediate sleeve and the inner sleeve and on the inner wall of the inner sleeve respectively, the outer sleeve, the first rubber layer, the intermediate layer, the second rubber layer, the inner sleeve and the third rubber layer are fixedly connected by means of vulcanized forming , and a trapezoidal opening through groove is arranged on the circumference of the rubber split bushing. The split bushing assembly for the automotive suspension has the advantages of reasonable structure, simplicity in process, high elasticity, excellent damping performance, certain rigidity and strength and long service life.
Description
technical field [0001] The invention relates to an open bushing assembly for an automobile suspension, belonging to the technical field of manufacturing rubber shock absorbers for automobiles. Background technique [0002] Recently, most of the bushings adopt the inner and outer two-layer skeleton structure, and rubber is filled between the two skeletons. The inner and outer skeletons are made of metal, and are an integral structure. When assembling, the accuracy of the outer diameter of the outer skeleton is used to ensure its tightness. , Due to various errors, it is easy to cause loose or too tight and deformed image, and the rubber clamped between the inner skeleton is limited, resulting in poor flexibility, poor cushioning, and unsatisfactory noise reduction and shock absorption effects; the rubber at both ends of the bush is exposed, It is easy to cause damage, accelerates the amount of rubber wear and shortens the service life of the bushing.
