Abstract
The utility model relates to a low-floor four-bar linkage type front air suspension used for a medium bus. The low-floor four-bar linkage type front air suspension comprises lower airbag supports, the lower airbag supports are fixed onto a front shaft through bolts, airbag assemblies are fixed to the upper ends of the lower airbag supports, the lower ends of shock absorbers are connected with the lower airbag supports, the upper ends of the shock absorbers are connected with a bus frame, one end of each upper traction bar is connected with the corresponding lower airbag support, the other ends of the upper traction bars are connected with the bus frame, one end of each lower traction bar is connected with the front shaft, the other ends of the lower traction bars are connected with the bus frame and stabilizer bars are connected with the two lower airbag supports. According to the low-floor four-bar linkage type front air suspension, an air spring is used for replacing a steel plate spring to be used as an elastic element, the rigidity of the air spring is low and the offset frequency of the air spring is low, so that ground buffer loads can better be buffered, and therefore driving smoothness and comfort of a finished vehicle can be greatly improved; the advantages of spatial structure arrangement of the air suspension are fully utilized, and therefore the performance requirements for reducing the height of a driving area, widening a channel, reducing the height of a floor and an inlet and the like are met.
Description
technical field:
The utility model relates to passenger vehicle parts technical field, is specifically related to a kind of medium bus low floor four connecting rod front air suspensions.
background technology:
Bus, school bus in existing city traffic all belong to medium bus field, along with China's expanding economy, improving constantly of people's quality of life, the high level performance requirements such as people are no longer only confined to its transport capacity aspect to the operating needs of bus, traveling comfort, road-holding property and the safety of people to bus also progressively improve.The medium-sized bus suspension system of most domestic is plate spring suspension brackets at present, and especially domestic school bus is all plate spring suspension brackets substantially.But plate spring suspension system rigidity is large, poor to the damping capacity of ground impact load, and then can cause the ride comfort of car load and traveling comfort poor.Therefore, the plate spring suspension system on existing bus can not meet the requirement of traveling comfort, ride comfort and the safety of people to bus.
utility model content:
In sum, in order to overcome the deficiency of prior art problem, the utility model provides a kind of medium bus low floor four connecting rod front air suspensions, its elastic element adopts air bellow to replace steel spring, because of the rigidity of air bellow little, offset frequency is low, can better relax ground impact load, and then can greatly improve riding comfort and the traveling comfort of car load.And make full use of the preceence that air suspension space structure is arranged, reach the height that reduces driver zone, strengthen passage width, the performance requriementss such as the height of reduction floor and entrance.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of low floor four connecting rod front air suspensions for medium bus, wherein: comprise front axle, air bag lower bracket, stabilizer rod, lower thrust rod, upper thrust rod, bumper and air bag component, air bag lower bracket is bolted on front axle, air bag lower bracket upper end is fixed with air bag component, bumper lower end is connected with air bag lower bracket, bumper upper end is connected with vehicle frame, one end of upper thrust rod is connected with air bag lower bracket, the other end is connected with vehicle frame, lower thrust rod one end is connected with front axle, its other end is connected with vehicle frame, and stabilizer rod connects two air bag lower brackets.
Further, described air bag lower bracket comprises body, body is triangular structure, the bottom of body arranges front axle fixed orifice, the upper end of body arranges air bag mounting hole, body right middle is provided with upper thrust rod connecting bore, and body bottom left arranges bumper mounting hole, and the right bottom of body is provided with stabilizer rod connecting bore.
Further, the middle part of described front axle is fixed with lower thrust rod Connection Block.
Further, the quantity of described lower thrust rod is two, and two lower thrust rods are " V " type and arrange.
The beneficial effects of the utility model are:
1, elastic element of the present utility model adopts air bellow to replace steel spring, and because the rigidity of air bellow is little, offset frequency is low, can better relax ground impact load, and then can greatly improve riding comfort and the traveling comfort of car load.And make full use of the preceence that air suspension space structure is arranged, reach the height that reduces driver zone, strengthen passage width, the performance requriementss such as the height of reduction floor and entrance.
2, the utility model appropriate design air bag lower bracket and propelling rod length and and its locus of reasonable Arrangement, to obtain better vertical inclineding stability, thereby ensure to greatest extent riding stability and the road-holding property of vehicle; And realize the object of large passage width, reduction floor and entrance height.
3, air bag lower bracket integrated level of the present utility model is high, and air bag, bumper, upper thrust rod and stabilizer rod can be installed simultaneously, and simple in structure, integrated level is high, rationally takies space, chassis.
