Description

Lightweight rubber suspension

Technical Field

The utility model relates to an automotive suspension technical field specifically is a lightweight rubber suspension.

Background

Commercial vehicle chassis suspensions are divided into leaf spring suspensions, air suspensions and rubber suspensions according to the structure and damping elements. At present, plate spring suspension is selected for use to chassis suspension more than 90% of domestic commercial car, and along with the super and whole car lightweight development trend of domestic treatment, air suspension progressively uses and promotes on domestic commercial car chassis, is limited to air suspension cost higher, and air suspension still needs certain time at domestic popularization. The rubber suspension frame has the advantages of light weight and cost, and is popularized and used on domestic commercial vehicle chassis in recent years. Common rubber suspension on the market mainly contains parts such as saddle assembly, equalizing beam assembly and rubber spring, bumper shock absorber, auxiliary spring, and the part all adopts the tailor-welding technology, and single structure has further optimization in weight and the structural space that reduces.

SUMMERY OF THE UTILITY MODEL

In order to solve the problem, the utility model aims at providing a lightweight rubber suspension further reduces the weight of suspension on guaranteeing overall structure intensity basis.

In order to achieve the above purpose, the technical scheme of the utility model is that: the utility model provides a lightweight rubber suspension, including the saddle assembly, balanced beam assembly, rubber spring and bumper shock absorber, respectively through the both sides inclined plane fixed connection of the intermediate strut seat of rubber spring and balanced beam assembly middle part on the relative inclined plane in bottom of saddle assembly, the saddle assembly is connected through telescopic bumper shock absorber respectively with balanced beam assembly each side, balanced beam assembly both ends are fixed with the bulb sleeve pipe respectively, the intraductal rubber ball pivot that is provided with of bulb cover, the rubber ball pivot is vulcanized ball round pin, the middle spheroid of rubber ball pivot is located the bulb cover intraductally, and the axial of rubber ball pivot is fixed with the hole retaining ring.

Furthermore, the front side and the rear side of the saddle assembly and the equalizing beam assembly are respectively provided with a lifting lug support, and the lifting lug supports above and below the same side are fixedly connected through a limiting chain.

Furthermore, the limiting chain is penetrated by the pin shaft fixed in each lifting lug support.

Furthermore, two ends of the rubber spring are respectively vulcanized with an integrated fixing plate, and each fixing plate is respectively fixedly connected with the inclined plane of the corresponding saddle assembly or equalizing beam assembly through bolts and nuts.

Through above setting, the suspension is the important part of car, and present rubber suspension has possessed the lightweight, but the development of car is constantly progressive, requires further lightweight, consequently carries out further optimization comparison difficulty on basis before this, the utility model discloses then overcome above-mentioned difficulty, both can satisfy rubber suspension and bear the weight of the requirement, further reduced weight, optimized structure simultaneously again, mainly demonstrate:

1. the saddle assembly is connected with the equalizing beam assembly through the rubber spring, so that a transition structure is simplified, and a spring support is eliminated;

2. the saddle assembly is not provided with a U-shaped connecting plate, adopts a lifting lug support structure and is connected with a limiting chain and a lifting lug support through a pin shaft;

3. the balance Liang Qiujiao is made of vulcanized ball pin, which is axially fixed by a hole check ring, and the interference fit structure of the existing ball hinge and the ball head sleeve is eliminated.

To sum up, the utility model discloses an optimization to rubber suspension structure both satisfies rubber suspension and bears the weight of the demand, has optimized the assembly structure again, has reduced assembly weight, has reduced installation, maintenance cost, accords with product lightweight, configuration optimization trend.
