Abstract
A connecting device for composite material plate spring and metal splint, comprises composite material plate spring, arranges pad between composite material plate spring and metal splint, and pad is non-metallic flexible material.Between composite material plate spring and metal splint, increase flexible gasket, because the elasticity of pad is good, it can have different deflections at two interfaces, thus plays the contact stress of minimizing metal pair composite material and the effect of wearing and tearing.Because the materials such as rubber have endergonic feature, certain damping effect can also be played, improve the NVH performance of composite material plate spring further.The friction force between clamping plate can also be increased when flexible gasket is bonded in composite material plate spring surperficial, thus play locating effect.
Description
Technical field
The utility model belongs to automotive field, is specifically related to the connecting device of a kind of composite material plate spring and metal splint.
Background technology
In recent years, due to the anxiety of the energy and the pressure of environmental protection, automotive light weight technology more and more becomes trend, and composite material plate spring also obtains increasing concern because of its special preceence.But the connection of leaf spring and vehicle also exists some problems, 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 connections design incorrect, will produce unnecessary stress and concentrate; If on composite material plate spring, punching will make greatly reduce the service life of leaf spring, thus affects the life-span of whole parts and normally use.
Summary of the invention
The utility model is to provide the connecting device of a kind of composite material plate spring and vehicle, concentrate with the wearing and tearing and reduction contact stress that reduce metal pair composite material plate spring, utilizing the high friction force between clamping plate and flexible gasket simultaneously, making composite material plate spring just can keep normal control position when not punching.
For achieving the above object, the utility model is by the following technical solutions:
A connecting device for composite material plate spring and metal splint, comprises composite material plate spring, arranges 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 material.
Described metal splint wraps composite material plate spring and pad completely.
Described pad is at least a slice.
The lining that described pad is integrated.
Composite material plate spring, metal splint, pad are provided with corresponding bolt hole, three fixes with bolt.
Connect with adhesive between described composite material plate spring and pad.
The utility model increases flexible gasket between composite material plate spring and metal splint, and because the elasticity of pad is good, it can have different deflections at two interfaces, thus play the contact stress of minimizing metal pair composite material and the effect of wearing and tearing.Because the materials such as rubber have endergonic feature, certain damping effect can also be played, improve the NVH performance of composite material plate spring further.The friction force between clamping plate can also be increased when flexible gasket is bonded in composite material plate spring surperficial, thus play locating effect.The utility model decreases the wearing and tearing of metal pair composite material plate spring, reduces contact stress and concentrates, also using the high friction force between clamping plate and flexible gasket simultaneously, making composite material plate spring also can keep normal operation position when not punching.Rubber sheet gasket can be connected in any form with composite material plate spring and clamping plate, in order to help location, and also can in pad central punch.

Detailed description of the invention
As shown in Figure 1, the connecting device of a kind of composite material plate spring and metal splint, comprise composite material plate spring 13, arrange 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 material.Shape and the thickness of metal splint are unrestricted, as the shape of metal splint in Fig. 2 21, also can be dull and stereotyped; As the shape of metal splint in Fig. 3 31, upper lower plate can wrap composite material plate spring and pad 32 at width and thickness direction altogether later completely; The connection of two clamping plate can also by the connection 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, and waiting width, also can be Varying-thickness, Trapezoidal; Half square shape flexible gasket shape can be oblong, also can be arbitrary shape.Pad has certain length, is generally longer than clamping plate length, but is not limited thereto, and the shape as Fig. 4 Intermediate gasket 42 is plane; Shape as Fig. 1 Intermediate gasket 12 extends to the thickness direction of composite material plate spring, is lived by the clamping position portion envelops of composite material plate spring; As the shape of Fig. 5 Intermediate gasket 52, also can extend to the thickness direction of composite material plate spring, the whole of composite material plate spring are stepped up portion envelops; Pad can be one or more pieces, also can be the lining of one.The shape of clamping plate and pad can combination in any use, and array mode is also not limited to above-mentioned citing, can not affect the life-span using composite material plate spring after pad.
