Abstract
Provided is a connecting device for a combined material plate spring and a metal lifting lug. The connecting device comprises the combined material plate spring. A linear is arranged at the connection part between the combined material plate spring and the metal lifting lug. The connection between the metal lifting lug and a fixing shaft is provided with a gasket. The metal lifting lug, the combined material plate spring and the liner are fixedly connected. Due to the fact that the linear or the gasket has great flexibility and has different deformation amount on two interfaces such that effects of contact stress concentration, abrasion and service lifetime are reduced due to contact between metal and combined material. Due to the fact that rubber and other high polymer material have the feature of absorbing energy, damping effect is exerted so that NVH performance of the combined material plate spring is further improved.
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 hanger.
Background technology
Noise (Noise), vibration (Vibration) and sound vibration roughness (Harshness, also referred to as " uneven pliable "), these problems being collectively referred to as " NVH " are increasingly becoming auto manufacturing and pay close attention to and the emphasis of research.Due to anxiety and the pressure of environmental conservation of the energy, automotive light weight technology increasingly becomes trend, and nonmetallic composite flat 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 such as composite material plate spring and middle splint and leaf spring two ends and the connection of metal hanger, if these connection are incorrect, will produce unnecessary stress concentration, thus affect the life-span of composite material plate spring and normally use.
Summary of the invention
It is an object of the invention to reduce metal abrasion and the contact stress of composite material plate spring are concentrated, the energy produced when simultaneously can also absorb vibrations, improve the NVH performance of vehicle.
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 hanger, including composite material plate spring, the part being connected with metal hanger at composite material plate spring arranges flexible liner, connecting portion at metal hanger and fixing axle arranges pad, fixing connection between metal hanger, composite material plate spring, lining.
Described lining is one end open or both ends open.
The end of described lining is arc or linear.
Described lining is non-metallic flexible material, is not limited to the one in rubber, polyurethane, nylon, PE, composite.
The part that the present invention is mainly connected with metal hanger in composite material plate spring end increases flexible liner or pad.Owing to the pliability of lining or pad is good, it can have different deflections at two interfaces, thus the stress concentration, abrasion and the impact on the life-span that reduce metal to contact with composite and produce, owing to the macromolecular materials such as rubber have the feature of absorption energy, certain damping effect can be played, improve the NVH performance of composite material plate spring further.
Accompanying drawing explanation
The structural representation of Fig. 1 present invention；
The structural representation that the end sections of composite material plate spring is wrapped up by Fig. 2 lining；
Fig. 3 lining is by structural representation fully wrapped around for the end of composite material plate spring.
Detailed description of the invention
As shown in Figure 1, a kind of composite material plate spring and the attachment means of metal hanger, including composite material plate spring, the part being connected with metal hanger 11 at composite material plate spring 16 arranges flexible liner 15, connecting portion at metal hanger 11 and fixing axle 13 arranges pad 12, between metal hanger 11, composite material plate spring 16, lining 15, fixing connection, can use bolt or rivet 14 to connect, depending on bolt or the number of rivet and size are according to the size of leaf spring and the size of load.The material of described flexible liner or pad is the non-metallic flexible material such as rubber, polyurethane, nylon, PE, composite.Described lining is one end open or both ends open, and the end of lining 25 as shown in Figure 2 is linear；The end of lining 35 as shown in Figure 3 can also be arc.Lining has the contact length of certain length, generally longer than metal hanger and composite material plate spring, but is not limited to this；Lining can be plane, it is also possible to extend to the thickness direction of leaf spring, as in figure 2 it is shown, the end sections of composite material plate spring is wrapped by lining 25；As it is shown on figure 3, lining 35 can also by fully wrapped around for the end of composite material plate spring live.Number and the lining shape of pad are not limited only to the example above.
The use process of the present invention is as follows: before composite material plate spring 16, metal hanger 11 and fixing axle 13 assemble, the part that composite material plate spring 16 is connected with metal hanger 11 arranges flexible liner 15, and the connecting portion at metal hanger 11 and fixing axle 13 arranges pad 12.Owing to the pliability of lining and pad is good, different deflections is had between two interfaces, metal hanger 11 and two interfaces of fixing axle 13 contact that it can contact with metal hanger 11 at composite material plate spring 16, thus the stress concentration, abrasion and the impact on the life-span that reduce metal hanger to contact with composite and produce, owing to the macromolecular materials such as rubber have the feature of absorption energy, certain damping effect can be played, improve the NVH performance of composite material plate spring 16 further.
