The utility model is used for on the multiaxle trucks, the inclined to one side mill of tire has also been reduced under the condition that reduces the wheel base as far as possible to make the frame atress more even, lighten the dead weight, simultaneously because the rigidity of balance arm is variable, increased the flexibility of design, improved the ride comfort of vehicle under the different load.
Description
Technical field
This utility model relates to the suspension field of multiple-axle vehicle, specifically a kind of variation rigidity leaf spring staggered form equalizing type of suspension, and it is big and need goods carrying vehicle and the engineering truck of Multi-shaft support that this equalizing type of suspension is suitable for loading capacity.
Background technology
Dependent plate spring suspension brackets as major part goods carrying vehicle and the preferred version of engineering truck rear overhang, it have simple structure, low cost of manufacture, easily keep in repair, the space that takies is little, can reduce the advantages such as car bottom plate height, applies wider in commercial car；But owing to the longitudinal size required for leaf spring is bigger, the rear suspension of multi-axis carrying vehicle and engineering truck uses four link type equalizing type of suspension mostly at present, i.e. the two supports of leaf spring in, on rear axle housing, be equivalent to an equiarm gimbal lever, it is with suspension mandrel as fulcrum, thus can ensure when automobile travels on rough road, each wheel can land, and in making, the vertical load mean allocation of back axle wheel.But the leaf spring of four link type equalizing type of suspension needs to carry two axletrees, loading capacity is relatively big, so the reed being generally used for the leaf spring of this form can be on the high side partially thick, comfortableness and ride comfort are the most poor；And between the equalizing type of suspension of this form and vehicle frame, using the connected mode of single-point support, this allows for vehicle frame load ratio at this junction point and relatively concentrates.
Patent No. " 201420833663.7 ", the earlier application of entitled " a kind of leaf spring staggered form equalizing type of suspension " have substantially solved ride comfort and the comfortableness problem of vehicle, in the case of reducing wheelbase as far as possible, also reduce the eccentric wear of tire simultaneously, make vehicle frame be more uniformly stressed.But in place of above-mentioned earlier application there is also certain shortcoming and defect, it is in particular in: the rigidity of counter-jib is immutable, it is impossible to preferably met the ride comfort requirement of vehicle by regulation rigidity.
Utility model content
The purpose of this utility model is to replace the counter-jib of above-mentioned patent with lamination leaf spring, in order to reduces system stiffness and improves the ride comfort of automobile；A kind of variation rigidity leaf spring staggered form equalizing type of suspension is provided, for multiple-axle vehicle, the eccentric wear of tire is also reduced in the case of reducing wheelbase as far as possible, and make vehicle frame be more uniformly stressed, alleviate deadweight, simultaneously because the variable rigidity of counter-jib, add the motility of design, improve the ride comfort of vehicle under different loads.
The purpose of this utility model is achieved in that
A kind of variation rigidity leaf spring staggered form equalizing type of suspension, this variation rigidity equalizing type of suspension includes propons, back axle, front plate spring, rear leaf spring, vehicle frame, vibroshock, U-bolt, front spring hanger, counter-jib support and rear spring hanger, it is characterized in that: it also includes that a compound leaf spring type counter-jib, described compound leaf spring type counter-jib include mainboard spring, subplate spring and bridle；The front end of mainboard spring is hinged with the lower end of front spring hanger, the rear end of mainboard spring and the upper end thereof of rear spring hanger；Described subplate spring is arranged on above mainboard spring by bridle；Described bridle is hinged with counter-jib support；Described front spring hanger is the most hinged with mainboard spring, and rear spring hanger is upwards hinged with mainboard spring.

A kind of variation rigidity leaf spring staggered form equalizing type of suspension, this variation rigidity equalizing type of suspension includes propons, back axle, front plate spring, rear leaf spring, vehicle frame, vibroshock, U-bolt, front spring hanger and balance arm support, it is characterized in that: it also includes that a compound leaf spring type counter-jib, described compound leaf spring type counter-jib include mainboard spring, subplate spring and bridle；The rear end of described mainboard spring is hinged with the lower end of front spring hanger, and the front end of mainboard spring is hinged with the front end of rear leaf spring；Described subplate spring is arranged on below mainboard spring by bridle, and described bridle is hinged with counter-jib support；Described front spring hanger is the most hinged with mainboard spring.
Advantage of the present utility model and good effect:
1, this utility model equalizing type of suspension is applicable to load truck and engineering truck, on the premise of ensureing that adjacent wheelbase does not increases, two subplate springs are used to arrange in same plane crossed longitudinally connection, improve the force-bearing situation of leaf spring, decrease the sheet number of every subplate spring, improve ride comfort and the comfortableness of vehicle, in the case of reducing wheelbase as far as possible, also reduce the eccentric wear of tire because of uniform load simultaneously.
2, using the connected mode of supported at three point between this utility model equalizing type of suspension and vehicle frame, and four link type balance is outstanding and uses the connected mode of single-point support between vehicle frame, the connected mode of supported at three point can make vehicle frame be more uniformly stressed, and alleviates deadweight.
3, compound leaf spring type counter-jib of the present utility model, along with the increase of Suspension Deformation, mainboard spring becomes larger with the contact area of subplate spring, and suspension rate is gradually increased, and has variation rigidity characteristic, improves the ride comfort of vehicle.
