Abstract
Provided is a connecting device for a combined material plate spring and a metal clamping plate. The connecting device comprises the combined material plate spring. A gasket is arranged between the combined material plate spring and the metal clamping plate. The gasket is made by nonmetal flexible material.Due to the fact that the flexible gasket is added between the combined material plate spring and the metal clamping plate, the gasket has better flexibility and has different deformation amount on two interfaces such that effects of reducing contact stress and abrasion of metal on combined material are exerted. Due to the fact that rubber has the feature of absorbing energy, damping effect is exerted so that NVH performance of the combined material plate spring is further improved.When the flexible gasket is adhered to the surface of the combined material plate spring, friction between the flexible gasket and the clamping plate is increased so that a positioning effect is exerted.
Description
Technical field
The invention belongs to automotive field, be specifically related to the attachment means of a kind of composite material plate spring and metal splint.
Background technology
In recent years, due to anxiety and the pressure of environmental conservation of the energy, automotive light weight technology increasingly becomes trend, and composite material plate spring has also obtained increasing concern because of its special superiority.But leaf spring there is also some problems with the connection of vehicle, have impact on the application of composite material plate spring.The connection of the connection of such as composite material plate spring and middle splint and two ends and metal hanger, if these connect and are designed to incorrect, will produce unnecessary stress and concentrate；If on composite material plate spring, punching will make be substantially reduced the service life of leaf spring, thus affect the life-span of whole parts and normally use.
Summary of the invention
The present invention is to provide the attachment means of a kind of composite material plate spring and vehicle, to reduce metal to the abrasion of composite material plate spring and reduction contact stress concentration, utilize the high frictional force between clamping plate and flexible gasket simultaneously, make composite material plate spring just can keep normal operating position in the case of not punching.
For achieving the above object, the present invention is by the following technical solutions:
A kind of composite material plate spring and the attachment means of metal splint, including composite material plate spring, arrange pad between composite material plate spring and metal splint.
Described pad is non-metallic flexible material, is not limited to the one in rubber, polyurethane, nylon, composite.
Described metal splint fully wrapped around firmly composite material plate spring and pad.
Described pad is the most a piece of.
The lining that described pad is integrated.
Being provided with the bolt hole of correspondence on composite material plate spring, metal splint, pad, three fixes with bolt.
Connect with adhesive between described composite material plate spring and pad.
The present invention is increase flexible gasket between composite material plate spring and metal splint, and owing to the pliability of pad is good, it can have different deflections at two interfaces, thus play and reduce the metal contact stress to composite and the effect of abrasion.Owing to the materials such as rubber have the feature of absorption energy, moreover it is possible to play certain damping effect, improve the NVH performance of composite material plate spring further.The frictional force between clamping plate can also be increased when flexible gasket is bonded in the surface of composite material plate spring, thus play locating effect.The present invention reduces the metal abrasion to composite material plate spring, reduce contact stress and concentrate, also use the high frictional force between clamping plate and flexible gasket simultaneously, make composite material plate spring also can keep normal operation position in the case of not punching.Rubber sheet gasket can be connected in any form with composite material plate spring and clamping plate, in order to help location, it is also possible in pad central punch.

Detailed description of the invention
As shown in Figure 1, a kind of composite material plate spring and the attachment means of metal splint, including composite material plate spring 13, arranging pad 12 between composite material plate spring 13 and metal splint 11, the material of described flexible gasket is the non-metallic flexible material such as polyurethane, nylon, composite.Shape and the thickness of metal splint are unrestricted, such as the shape of metal splint 21 in Fig. 2, it is also possible to be flat board；Such as the shape of metal splint 31 in Fig. 3, upper lower plate altogether later can fully wrapped around firmly composite material plate spring and pad at width and thickness direction；The connection of two clamping plate can also be by the connected mode of conventional metals leaf spring.
The shape of pad is not limited to the shape shown in Fig. 1.Pad can be equal thickness, equal in width, it is also possible to be Varying-thickness, Trapezoidal；Half square shape flexible gasket shape can be rectangle, it is also possible to be arbitrary shape.Pad has certain length, generally longer than clamping plate length, but is not limited to this, if the shape of Fig. 4 Intermediate gasket 42 is plane；As the shape of Fig. 1 Intermediate gasket 12 extends to the thickness direction of composite material plate spring, the clamping position portion envelops of composite material plate spring is lived；Shape such as Fig. 5 Intermediate gasket 52, it is also possible to extend to the thickness direction of composite material plate spring, whole by composite material plate spring step up portion envelops；Pad can be one or more pieces, it is also possible to is the lining of one.Clamping plate can be used in any combination with the shape of pad, and compound mode is also not necessarily limited to the example above, does not interferes with and uses the life-span of composite material plate spring after pad.
