Abstract
The invention relates to an independent pneumatic suspension without a supporting arm structure for a medium bus. The independent pneumatic suspension comprises a wheel rim. The upper portion of the wheel rim is hinged to one side of an upper swinging arm, and the other side of the upper swinging arm is connected with a frame through an upper bearing. The lower portion of the wheel rim is hinged to one side of a lower swinging arm, and the other side of the lower swinging arm is connected with the frame through a lower bearing. An air bag assembly is arranged on the upper portion of the upper swinging arm, the lower portion of the upper swinging arm is connected with the upper end of a stable rod lifting rod, the lower end of the stable rod lifting rod is connected with a stable rod, and the middle of the lower swinging arm is connected with the lower end of a shock absorber. Because a leaf spring is replaced by an air spring, good overall rigidity of the medium bus can be acquired, and the comfort of the whole bus can be improved. Meanwhile, the supporting arm structure of an original pneumatic suspension is not needed, the upper swinging arm and the lower swinging arm are directly hinged to the wheel rim, the wheel rim is connected with the frame through the upper swinging arm and the lower swinging arm, and therefore the number of parts of the medium bus is effectively reduced, and the production cost of the bus is reduced.
Description
technical field:
The present invention relates to passenger vehicle parts technical field, be specifically related to the independent air suspension of a kind of medium bus without hold-down arm structure.
background technology:
Along with China's expanding economy, the improving constantly of people's quality of life, user is no longer only confined to its transport capacity aspect to the operating needs of passenger vehicle, and people also progressively improve high level performance requirements such as traveling comfort, road-holding property and safetys.Therefore, traditional passenger vehicle suspension can not meet people's requirement, and people wish further energy-conservation, the lightweight of modern suspension frame structure.
The high performance of independent suspension is that common rigid bridge suspension is incomparable.According to national legislation < < JT/T 325-2006 operating passenger car type, divide and ranking requires the requirement of > >: super-huge Senior Three grade passenger vehicle must use front independent suspension system and follow-up bridge independent suspension system.But because independent suspension product structure is complicated, technical requirements is high, R&D costs are high, China existing passenger vehicle manufacturing enterprise can't produce the medium bus with independent suspension, therefore, how independent suspension system is applied in medium bus, for existing passenger vehicle manufacturing enterprise or a difficult problem.And, between existing independent air suspension vehicle wheel limit and vehicle frame, hold-down arm is all set, air bag component, upper and lower swing arm are all connected with hold-down arm, this kind of structure is equivalent to, between vehicle frame and vehicle wheel limit, transition piece is set, when design independent air suspension, the factor of the structure of necessary consideration hold-down arm, weight, installing space, the amount of parts of increase passenger vehicle, increase labor strength, increase passenger vehicle productive costs.
summary of the invention:
In sum, in order to overcome the deficiency of prior art problem, the invention provides the independent air suspension of a kind of medium bus without hold-down arm structure, use air bellow instead of steel laminated spring can obtain good rigidity of the vehicle, improve the traveling comfort of car load.Cancelled the hold-down arm structure of original air suspension simultaneously, upper and lower swing arm is direct and vehicle wheel limit is hinged, vehicle wheel limit is connected with vehicle frame by pumping arm action, thereby actv. reduces the amount of parts of medium bus, reduce passenger vehicle productive costs, in passenger vehicle motion process, can separately beat in the left and right limit of taking turns simultaneously, therefore can reduce inclination and the vibration of vehicle body, improve ride comfort and the maneuvering performance of car load.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
The independent air suspension of a kind of medium bus without hold-down arm structure, wherein: comprise vehicle frame, vehicle wheel limit, top link, lower swing arm, air bag component, bumper, stabilizer rod and stabilizer rod suspension rod, described top, vehicle wheel limit and a side of top link are hinged, the opposite side of top link is connected by head bearing with vehicle frame, one side of the bottom on vehicle wheel limit and lower swing arm is hinged, the opposite side of lower swing arm is connected by lower bearing with vehicle frame, the top of top link is provided with air bag component, the bottom of top link is connected with the upper end of stabilizer rod suspension rod, the lower end of stabilizer rod suspension rod is connected with stabilizer rod, the middle part of described lower swing arm is connected with bumper lower end.
Technical scheme of the present invention is opened and can be achieved in that described air bag component comprises base, air bag and upper cover plate, and base lower end is connected with top link, and base upper end is provided with air bag, and air bag upper end is provided with upper cover plate.
Technical scheme of the present invention is opened and can be achieved in that between described air bag and upper cover plate and be provided with limiting stopper.
Vehicle wheel limit and top link that technical scheme of the present invention is opened described in can being achieved in that are hinged by ball pivot.
Vehicle wheel limit and lower swing arm that technical scheme of the present invention is opened described in can being achieved in that are hinged by ball pivot.
Technical scheme of the present invention is opened and can be achieved in that described head bearing and lower bearing are rubber shaft bearing.
Beneficial effect of the present invention is:
1, the present invention uses air bellow instead of steel laminated spring can obtain good rigidity of the vehicle, improves the traveling comfort of car load.Cancelled the hold-down arm structure of original air suspension simultaneously, upper and lower swing arm is direct and vehicle wheel limit is hinged, vehicle wheel limit is connected with vehicle frame by pumping arm action, thereby actv. reduces the amount of parts of medium bus, reduce passenger vehicle productive costs, in passenger vehicle motion process, can separately beat in the left and right limit of taking turns simultaneously, therefore can reduce inclination and the vibration of vehicle body, improve ride comfort and the maneuvering performance of car load.
2, between the upper and lower swing arm of the present invention and vehicle frame, by rubber shaft bearing, connect, to realize, flexibly connect, reduce the problems such as noise, wearing and tearing.
3, the present invention is owing to having cancelled rigid shaft, and nonspring carried mass of the present invention is lighter, only has 1/2nd of rigid bridge airsuspension system.Less sprung mass and nonspring carried mass, improved the riding comfort of car load, increased the ground connection performance of tire, reduced the impact to vehicle body, increased the service life of car load.Reduce complete vehicle quality simultaneously, saved oil consumption, reduced operating cost.
4, the present invention is simple in structure, easy to use, cancelled the hold-down arm on original air suspension vehicle frame and vehicle wheel limit, actv. has reduced the amount of parts of medium bus, reduce complete vehicle weight, stability and the operability of bus driving have been guaranteed, reduce passenger vehicle productive costs simultaneously, improve market competitiveness of enterprises.
