Abstract
The utility model provides a rubber bushing which comprises an inner metal tube. Rubber is arranged on the outer side of the inner metal tube; and an outer metal tube is arranged on the outer side of the rubber. The rubber bushing is characterized in that the inner metal tube has a pillow-shaped ball type structure. The rubber bushing has the advantages that when the assembly conditions of a product are met, the rigidity requirement of the rubber bushing can be met without adjusting the rubber compounding, thereby ensuring the product fatigue and safety performance and reducing production cost.
Description
Technical field
The utility model relates to a kind of rubber bush, is used to connect each suspension link of car chassis, belongs to the rubber bush technical field.
Background technology
In order to strengthen the handling of automobile, need to increase the rigidity of its suspension, therefore all very high to the rigidity requirement that connects the rubber bush between each suspension link.Existing rubber bush as shown in Figure 1, at the arranged outside rubber 2 of metal inner pipe 1, in the arranged outside metal outer pipe 3 of rubber 2, the cross section of metal inner pipe 1 is rectangular, metal inner pipe 1 to the distance between the metal outer pipe 37 is 7mm.
Should satisfy under the situation that rigidity satisfies assembled condition again, way in the past is to adjust the prescription of rubber 2, improves the hardness of rubber 2, makes the rigidity of rubber bush promote.After but the hardness of rubber 2 promotes, must cause the fatigue property decline of rubber bush and the reduction of safety performance.Want to overcome these shortcomings, can only be with some good rubber raw materials, cost also can improve thereupon like this.
The utility model content
The purpose of this utility model provide a kind of simple in structure, with low cost, do not changing under the product assembled condition, can improve the rigidity of rubber bush own and can satisfy the tired rubber bush that requires of product again.
In order to achieve the above object, the technical solution of the utility model has provided a kind of rubber bush, comprises metal inner pipe, the outside at metal inner pipe is provided with rubber, the outside at rubber is provided with metal outer pipe, it is characterized in that, described metal inner pipe is a pillow type ball formula structure.So-called pillow type ball formula structure is meant that the two ends of the vertical section of metal inner pipe are rectangle, and the centre is an arc-shaped protrusions.
Because metal inner pipe has adopted pillow type ball formula structure, reduced the spacing of outer tube to interior pipe, suitably promoted the radial rigidity of this lining.And pipe has just strengthened torsional stiffness a little than the interior pipe of first pre-structure in the pillow type ball, to rubber bush fatigue property and assembled condition did not influence, can improve product rigidity by the lifting rubber hardness.
The utility model has the advantages that: satisfying under the product assembled condition, do not needing to satisfy the rigidity requirement that rubber bush is proposed, guaranteeing product fatigue and safety performance, reducing productive costs simultaneously by the debugging of rubber compounding.
Description of drawings
Fig. 1 is the structural representation of former rubber bush;
The structural representation of a kind of rubber bush that Fig. 2 provides for the utility model.
The specific embodiment
Specify the utility model below in conjunction with embodiment.
Embodiment
As shown in Figure 2, the structural representation of a kind of rubber bush that provides for the utility model is made up of rubber 2, metal outer pipe 3 and metal inner pipe 4.
Be provided with rubber 2 in the outside of metal inner pipe 4, be provided with metal outer pipe 3 in the outside of rubber 2, metal inner pipe 4 is a pillow type ball formula structure.The summit of metal inner pipe 4 to the distance 5 between described metal outer pipe 3 inwalls is 5mm.The rubber bush of present embodiment is all meeting the requirements of times of fatigue when the stand fatigue test after and phenomenon of rupture does not take place.
Claims (2)
1. a rubber bush comprises metal inner pipe (4), is provided with rubber (2) in the outside of metal inner pipe (4), is provided with metal outer pipe (3) in the outside of rubber (2), it is characterized in that, described metal inner pipe (4) is a pillow type ball formula structure.
2. a kind of rubber bush as claimed in claim 1 is characterized in that, the summit of described metal inner pipe (4) to the distance (5) between described metal outer pipe (3) inwall is 5mm.
