Embodiment 1
[0023] like Figure 1-3 As shown, a rear axle bushing of a non-independent suspension includes an inner sleeve 1 assembly, an outer sleeve 2 and a rubber body 3. The inner sleeve 1 assembly is arranged in the middle of the inner cavity of the outer sleeve 2, including a cylindrical The inner sleeve 1 and the circular support plate 11 arranged at the outer edge of one end of the inner sleeve 1, the inner sleeve 1 and the support plate 11 are made of metal, so that the bushing has a certain rigidity, and the support plate The diameter of 11 is larger than the diameter of the inner sleeve 1, and the support plate 11 is fixedly connected with the inner sleeve 1, so as to improve the axial durability and torsional durability of the bushing.
[0024] The middle part of the outer surface of the inner casing 1 is fixed with a rectangular torsion reinforcing plate 13 in the transverse direction. The torsion reinforcing plate 13 is made of metal material. The torsional force between 3 ...

The invention relates to a rear axle bushing for rigid axle suspension. The rear axle bushing comprises an inner sleeve assembly, an outer sleeve and a rubber body; the inner sleeve assembly is arranged in the middle of an inner cavity of the outer sleeve and comprises an inner sleeve and a circular supporting plate arranged at the outer edge of one end of the inner sleeve; a rectangular torsion reinforced plate is transversely and fixedly arranged in the middle of the outer surface of the inner sleeve; and the rubber body is arranged between an inner bushing body and an outer bushing body, and a plurality of damping holes are evenly formed in the rubber body. By designing the supporting plate and the torsion reinforced plate in the inner sleeve of the bushing, the bushing has certain rigidity, and axial durability and torsion durability of the bushing are improved; and by designing the close-up-type outer sleeve, stress of rubber arranged in the outer sleeve is dispersed advantageously, the service life of the bushing is prolonged, through a structure, the bonding area of the rubber and the outer sleeve is increased, the bonding strength of the rubber is improved, and the servicetime of the bushing is further prolonged.
Description
technical field [0001] The invention belongs to the technical field of vehicles, and in particular relates to a rear axle bush of a non-independent suspension. Background technique [0002] With the rapid development of the economy and the substantial improvement of people's living standards, people have obviously higher requirements for the quality of life. Automobiles have become an indispensable means of transportation and transportation in people's lives today. Today, with the popularization of cars, people's demand for cars is not only fuel and vehicle safety, but also ride comfort has become the primary factor people consider when buying a car. Suspension is the general term for all force-transmitting connection devices between the frame of a car and the axle or wheels. The main function of the suspension is to transmit all forces and moments acting between the wheels and the body, such as supporting force, braking force and Driving force, etc., and ease the impact l...
