Composite spring for vehicle suspension, vehicle suspension and vehicle

Technical Field

The utility model relates to an elastomeric element for the vehicle especially relates to a combined type spring.

Background

As is known, a suspension spring is one of the important components of an automobile suspension, and it can function as follows: the vehicle suspension system has the advantages that firstly, the suspension system has a buffering effect, and a spring for a vehicle suspension can convert one-time large-energy impact on a vehicle wheel into multiple times of small-energy impact; and secondly, the bounce of the wheels caused by the uneven road surface can be reduced through the expansion and contraction characteristics of the spring, so that the wheels are kept in contact with the ground as much as possible, and the driving comfort of a user is improved.

Currently, conventional suspension spring structures are typically purely metallic and do not employ any shielding in the prior art. The disadvantages of this structure are: firstly, foreign matters are easily mixed in the transition ring of the spring, and the transition ring moves all the time and is very easy to wear, so that the spring is broken; secondly, the end ring is matched with a peripheral part during assembly, and only the plane type end ring can be designed, so that the design space of the spring is limited; thirdly, the spring of this kind of structure, can't directly assemble on the rear axle assembly, so can only carry out final assembly on the automobile production line, very influence the final assembly efficiency.

In special cases, conventional suspension springs can also be provided with a plastic protective sleeve on the end ring. The design is substantially only that a plastic protective sleeve is added on the basis of the traditional metal piece spring structure, the protective effect on the transition ring is limited, and the plastic protective sleeve is easy to age so as to lose the protective function.

Based on this, to the defect among the prior art, the utility model discloses expect to obtain a combined type spring for vehicle suspension, its can fundamentally stop the appearance of the wearing and tearing condition of end ring transition circle under the spring to can avoid the combined type spring fracture because this reason leads to completely.

Furthermore, it is another object of the present invention to provide a vehicle that can have the vehicle suspension described above.

A combined type spring, vehicle suspension and vehicle for vehicle suspension have following advantage and beneficial effect:

combined type spring can fundamentally stop the appearance of the wearing and tearing condition of spring lower extreme circle transition circle to can avoid completely because the combined type spring fracture that this reason leads to, it has very good popularization prospect and using value.

Correspondingly, in vehicle suspension and vehicle, adopted foretell combined type spring, it has above-mentioned advantage and beneficial effect equally.

Detailed Description

The composite spring for a vehicle suspension according to the present invention will be further explained and illustrated with reference to the drawings and the specific embodiments, however, the explanation and illustration are not to be construed as an undue limitation on the technical solution of the present invention.

As shown in fig. 1, in the present embodiment, the composite spring of the present invention may include: a spring body 1, a first spring pad 2, a support 3 and a spring holder 4. The first spring pad 2 may be disposed at a lower end of the spring body 1 in the axial direction; the support 3 may be fixedly disposed on the spring plate 4 and disposed below the first spring pad 2, detachably connected to the first spring pad 2.

When the design, can design the internal surface of first spring pad 2 into with the tip adaptation of spring body 1 to first spring pad 2 improves with the inseparable cooperation of spring body 1 the utility model discloses a quality of combined type spring.

It should be noted that, in order to obtain better quality, the combined spring of the present invention may further be provided with a second spring pad 5, in this embodiment, the second spring pad 5 may be disposed at the upper end of the spring body 1 in the axial direction.

As shown in fig. 2 and 3, in the present embodiment, the first spring pad 2 may be a rubber spring pad, and the support 3 may be a plastic support.

The lower surface of the first spring pad 2 of the composite spring of the present invention may further have a buckle 21, and the upper surface of the supporting member 3 may have a slot 32 (as shown in fig. 4). The first spring pad 2 and the support 3 can be detachably connected by the cooperation of the buckle 21 and the clamping groove 32.

In the present embodiment, the first spring pad 2 and the spring body 1 may be bonded to each other. By coating the surfaces of the first spring pad 2 and the second spring pad 5 with a dedicated adhesive, after sufficient oxidation, the first spring pad 2 and the second spring pad 5 can be assembled to the spring body 1, and then the spring body 1 and the first spring pad 2 and the second spring pad 5 are bonded through a heating and static pressing process. The design can ensure that relative movement is not generated between the end ring of the spring body 1 and the first spring pad 2 and the second spring pad 5, thereby realizing long-term effective protection on the surface of the spring transition ring.

As shown in fig. 4, in the present embodiment, two buckles 21 are designed on the first spring pad 2, two slots 32 are correspondingly designed on the plastic support 3, and the first spring pad 2 and the support 3 can be fixed by the cooperation of the buckles 21 and the slots 32, so as to prevent relative movement between the first spring pad 2 and the support 3.

Further, in the present embodiment, the lower surface of the support 3 has a pin 31 protruding downward, and the support 3 may be fixedly provided on the spring holder 4 by the pin 31. In the present invention, the support member 3 of the composite spring may be provided with at least three pins 31.

This design allows the support member 3 to be mounted directly to the spring holder 4, avoiding direct relative movement of the support member 3 and the spring holder 4. Meanwhile, the design gives the supporting piece 3 the matching work with the spring disc 4, so that the design space of the end ring of the spring body 1 is larger, and the design of the spring is more facilitated. Above all, the whole spring body 1 can be directly assembled on a rear axle assembly, and then the axle assembly is supplied to a production line together for final assembly, so that the total assembly efficiency in the production process can be greatly improved.

It should be noted that, after all the way test runs that have ended at present, combined type spring lower extreme circle transition circle wear rate be 0, and the spring of test on the platform before, the spring of circle transition circle is 100% under the spring, and its transition circle wearing and tearing are very serious, lead to the spring fracture easily.

In conclusion, can see that, combined type spring can fundamentally stop the appearance of the wearing and tearing condition of end ring transition circle under the spring to can avoid completely because the combined type spring fracture that this reason leads to, it has very good popularization prospect and using value.
