Abstract
The utility model relates to an independent front air suspension for a medium-sized bus. The independent front air suspension for the medium-sized bus comprises two guiding arms which are arranged in parallel, wherein the front ends of the guiding arms are movably connected with the lower end of a support, the upper part of the support is fixed with a car frame, the middle parts of the guiding arms are connected with an airbag lower support which is fixed on a front bridge, the lower end of an airbag shock absorbing module is connected with the airbag lower support, the upper end of the airbag shock absorbing module is connected with an airbag upper support, the airbag upper support is fixed on the car frame, and the back ends of the two parallel guiding arms are connected through a horizontal stable beam. The front air suspension combines an airbag component and a shock absorber into the airbag shock absorbing module, a dependent stable rod structure is omitted, the horizontal stable beam structure is arranged between the guiding arms, the whole weight reduction of the suspension is realized on the premise of guaranteeing the function of the front air suspension, the number of the components of the front air suspension is reduced, the arrangement space is reduced, and the assembling efficiency of the front air suspension is improved.
Description
technical field:
The utility model relates to passenger vehicle parts technical field, is specifically related to a kind of medium bus dependent front air suspension.
background technology:
Current domestic medium bus front air suspension frame system used (dependent suspension) is four connecting rods or single trailing arm type structure, and these two kinds of suspensions all exist shortcoming:
(1) air bag component and bumper are two parts separately, realize separately the function of oneself, two parts in passenger vehicle operational process, just need in front air suspension frame system, design two installation sites, cause front air suspension parts many, complex structure, difficult arrangement;
(2) two of existing front air suspension frame system air bags communicate, and by a valve control, the anti-roll capability of car load are not contributed substantially.In order to increase roll angular rigidity, improve the anti-roll capability of car load, Panhard rod all can be installed in suspension, but so will increase the numerous parts such as stabilizer rod suspension rod, stabilizer bar bushing, stabilizer rod boom support, increase suspension weight on the one hand, had a strong impact on the other hand the layout of suspension system and the installation effectiveness of suspension.
utility model content:
In sum, in order to overcome the deficiency of prior art problem, the utility model provides a kind of medium bus dependent front air suspension, it is that the air bag component of front air suspension and bumper are merged into an air bag damping module, cancel independent stabilizator rod structure simultaneously, a lateral stability girder construction is installed in the middle of guide arm, ensureing under the prerequisite of front air suspension function, realize the overall weight that reduces suspension, reduce the amount of parts of front air suspension, save the efficiency of assembling of arrangement space and raising front air suspension.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of medium bus dependent front air suspension, wherein: comprise two guide arms that be arranged in parallel, the front end of guide arm is flexibly connected with support lower end, support top and vehicle frame are fixed, the middle part of guide arm is connected with the air bag lower bracket being fixed on propons, and air bag damping module lower end is connected with air bag lower bracket, and air bag damping module upper end is connected with air bag upper bracket, air bag upper bracket is fixed on vehicle frame, and the rear end of two parallel guide arms connects by lateral stability beam.
Further, described air bag damping module comprises air bag and bumper, and bumper lower end is connected by rubber shaft bearing with air bag lower bracket, and bumper upper end is connected with air bag lower end, and air bag upper end is connected with air bag upper bracket.
Further, described guide arm front end is connected by rubber shaft bearing with support lower end.
The beneficial effects of the utility model are:
1, the utility model is that the air bag component of front air suspension and bumper are merged into an air bag damping module, cancel independent stabilizator rod structure simultaneously, a lateral stability girder construction is installed in the middle of guide arm, ensureing under the prerequisite of front air suspension function, realize the overall weight that reduces suspension, reduce the amount of parts of front air suspension, save the efficiency of assembling of arrangement space and raising front air suspension.
2, the utility model uses air bag vibration damping module as elastic element and damping element, replace traditional air bag component (comprising air-bag base, air bag, bump rubber, air bag cover plate) and shock absorber, realize support and the prerequisite of damped vibration function under, greatly reduced amount of parts, improved the efficiency of assembling of suspension.
3, two parallel guide arm rear ends of the present utility model connect by lateral stability beam, lateral stability beam replaces traditional horizontal stabilizer bar structure, has reduced the required space of Panhard rod and stabilizer rod suspension rod, stabilizer rod boom support, stabilizer bar bushing etc. to be installed the required parts of Panhard rod are installed.Optimize structure, reduce the target of complete vehicle weight and integral vehicle cost to reach.
4, the amount of parts of airsuspension system of the present utility model greatly reduces, and suspension frame structure is compacter, easy to assembly simultaneously, is beneficial to the layout of car load and the facility of maintenance; On the basis of reliability requirement that ensures air suspension, optimize component structural, expendable weight, reaches the object that reduces vehicle operating cost.
