Abstract
The utility model belongs to field of automobile design, and in particular to a kind of equalizing-suspension device, including equalizing type of suspension, few leaf spring, and U-bolt, " T " type structure cover board；Few leaf spring is mounted on the support of equalizing type of suspension, " T " type structure cover board is mounted on few leaf spring upper center, U-bolt by equalizing type of suspension, few leaf spring, " the series connection fastening of T " type structure cover board；The U-bolt is unilateral 4 pull-up structures.The utility model falls to draw braking balance suspension+few piece spring structure by using unilateral 4 U-bolts, and the weight of system can be made to reduce 180-360kg, contributed for the lightweight of vehicle.The pretightning force that leaf spring clamps is improved, avoids pretightning force deficiency that leaf spring is caused to be broken.Convenient for tightening up U-bolt, maintenance efficiency is improved, maintenance cost is reduced.
Description
Technical field
The utility model belongs to field of automobile design, and in particular to a kind of equalizing-suspension device.
Background technique
Traditional heavy truck engineering truck equalizing type of suspension is outstanding using integrated balancing suspension+multiple-leaf spring or breakaway-element balance
Frame+multi-disc spring structure, equalizing suspension system weight weight, cost are also relatively high；Braking balance suspension+few 2 U-shaped spiral shells of leaf spring
The positive pull-up structure of bolt, pretightning force is relatively low, tightens up U-bolt difficulty, and maintenance efficiency is low, and maintenance cost is high.
Summary of the invention
The purpose of this utility model is to provide a kind of equalizing-suspension devices, break by using 4 U-bolts in unilateral side
Open type equalizing type of suspension+few piece spring structure, can make the weight of system reduce 180-360kg, contribute for the lightweight of vehicle.It mentions
The pretightning force that high leaf spring clamps, avoids pretightning force deficiency that leaf spring is caused to be broken.Convenient for tightening up U-bolt, maintenance efficiency, drop are improved
Maintenance cost.Specific technical solution is as follows:
A kind of equalizing-suspension device, including equalizing type of suspension, few leaf spring, U-bolt, " T " type structure cover board；Few leaf spring installation
On the support of equalizing type of suspension, " T " type structure cover board is mounted on few leaf spring upper center, and U-bolt is by equalizing type of suspension, few piece
Spring, " the series connection fastening of T " type structure cover board；The U-bolt is unilateral 4 pull-up structures.
The utility model has the beneficial effects that
1) based on unilateral 2 U-bolt traction fracture open type equalizing type of suspensions+few piece spring structure equalizing type of suspension, in line with
It is solid to realize that unilateral 4 U-bolts fall to tense for the general premise of balance suspension support rigging position, equalizing type of suspension newly developed.
2) design matches few leaf spring, meets requirement of the vehicle to equalizing suspension system design input, meet vehicle carrying and
The requirement of ride comfort.
3) designing " cover board of T " type structure guarantees leaf spring cover board when equalizing type of suspension leaf spring is rotated to limit operating position
Movement interference is not generated with balance suspension support.
4) based on unilateral 2 U-bolt traction fracture open type equalizing type of suspensions+few piece spring structure equalizing type of suspension, in line with
It is solid to realize that unilateral 4 U-bolts fall to tense for the general premise of balance suspension support rigging position, equalizing type of suspension newly developed.
5) design matches few leaf spring, meets requirement of the vehicle to equalizing suspension system design input, meet vehicle carrying and
The requirement of ride comfort.
6) designing " cover board of T " type structure guarantees leaf spring cover board when equalizing type of suspension leaf spring is rotated to limit operating position
Movement interference is not generated with balance suspension support.
Detailed description of the invention
Fig. 1 is the equalizing-suspension device structural schematic diagram of the utility model；
Specific embodiment
The utility model is described in further detail in the following with reference to the drawings and specific embodiments.
Embodiment 1
A kind of equalizing-suspension device, including equalizing type of suspension 1, few leaf spring 2, U-bolt 3, " T " type structure cover board 4；Few piece
Spring 2 is mounted on the support of equalizing type of suspension 1, " T " type structure cover board 4 is mounted on few 2 upper center of leaf spring, and U-bolt 3 will balance
Suspension 1, less leaf spring 2, " the series connection fastening of T " type structure cover board 4；The U-bolt 4 is unilateral 4 pull-up structures.
The utility model matches few piece spring structure using unilateral 4 U-bolt braking balance suspensions, makes the weight of system
180-360kg is reduced, is contributed for the lightweight of vehicle；The pretightning force for improving leaf spring clamping is reduced because of U-bolt pine
The dynamic probability for causing leaf spring to be broken；Operation when tightening up convenient for U-bolt improves maintenance efficiency, reduces maintenance cost；It realizes
With unilateral 2 U-bolt traction fracture open type equalizing type of suspensions+general requirement in few leaf spring Standard position, it is convenient for vehicle not
The requirement to change the outfit is used with load and operating condition.
