Description
Technical field
The invention belongs to highway transportation field, specifically a kind of suspension device for vehicle.
Background technology
Suspension arrangement of semitrailer is one of critical piece of semitrailer, and its main function is semitrailer axle moving component
It is tied effectively and reasonably, securely with semitrailer crossbeam.In the prior art in one of Application No. 2005101289753
State's patent discloses a kind of suspension device of chassis and the semitrailer with the suspension arrangement, the technical scheme include front spring bracket,
Middle spring bracket and back spring scaffold, are equipped with car between front spring bracket and middle spring bracket and between middle spring bracket and back spring scaffold
Axle central siphon and leaf spring, leaf spring are located at below axletree central siphon；Front spring bracket and back spring scaffold are welded on the master of semitrailer
The side-lower of crossbeam, stayed mast is located above the side of leaf spring, and the technical scheme reduces chassis by the setting of stayed mast
The height of suspension arrangement, improves the stability and security of vehicle.Using the semitrailer of above-mentioned suspension arrangement, when wheel is different
When contact ground when, hanging wheel does not provide support force, and the load increasing that wheel contact with ground is subject at this moment just occurs
Tyre break, the situation of leaf spring fracture are caused greatly.
For above-mentioned technical problem, a Chinese patent of Application No. 200720126993.2 discloses a kind of semitrailer
Suspension arrangement, including suspension holdfast, vehicle bridge, dumb iron, leaf spring, it is characterised in that：The leaf spring branch
Frame is welded on the top of vehicle bridge, and slotted eye is respectively equipped with propons dumb iron and Rear Axle Steel Plate spring support bottom, correspondence
The position of the slotted eye, the bottom of leaf spring is provided with folding hook, and the folding hook is hooked on the propons and back axle spring support respectively
Slotted eye in；The suspension holdfast is by being pivotally hinged on carrier base, and carrier base is arranged on leaf spring by U bolt
Middle part.Using the semitrailer of the technical scheme, when wheel is different during contiguously face, in the presence of leaf spring, steel plate bullet
Spring can drive hanging wheel active exposure ground to be provided for semitrailer around pivoting for suspension holdfast and carrier base is hinged
Support force, so as to prevent piece wheel by the excessive situation for causing disconnected spring, off-axis, blowing out of load.
Although above-mentioned technical proposal solves the problem of tire force is excessive, but it brings problems with：
1. as shown in Fig. 2 being connected between the leaf spring 5 and dumb iron 7 for contact so that leaf spring
5 rocked in dumb iron 7 cause between larger noise, and leaf spring 5 and dumb iron 7 be unlubricated friction
Wipe, on the one hand meeting output noise, another aspect leaf spring 5 can produce abrasion with dumb iron 7 so that leaf spring branch
Frame 7 is easy to damage and cause security incident.
2. from the angle analysis of stress, when all tire is simultaneously hanging, the height of jackshaft can be higher than under gravity
The height of propons and back axle, the gravitional force that this allows for jackshaft is larger, when tire lands, the tire meeting on propons and back axle
First land but not bear larger support force, only leaf spring just plays branch when the tire in three vehicle bridge lands simultaneously
The effect of support, because the position of jackshaft is of a relatively high so that the gravitional force of jackshaft is larger, so that what leaf spring was subject to
Impulsive force is larger, and then the situation for easily causing disconnected spring, blowing out.
In consideration of it, a kind of suspension device for vehicle that the present invention is provided, can either prevent that the load that local tire is subject to is excessive,
It can be good at reducing the friction of junction again, reduce noise, it specifically has the beneficial effect that：
