Abstract
The utility model relates to a full air front suspension frame of an ultra low floor city passenger car steering axle. A longitudinal beam of a car frame forms an arc shape and is fixedly connected with a cross beam. Air bag supporting seats of both sides are fixed to both ends of a front axle through a shim plate. The middle part of the front axle is fixedly connected to a distance rod supporting seat. One end of each of two V-shaped distance rods is movably connected to the distance rod supporting seat, and the other end of each of two V-shaped distance rods is movably connected to a supporting seat fixed to a lower cross beam. One end of each of longitudinal direction distance rod of both sides is movably connected to the air bag supporting seats, and the other end of each of longitudinal direction distance rod of both sides is movably connected to a longitudinal distance rod supporting seat fixed to an upper cross beam. The lower part of each of air bag assemblies of both sides is fixedly connected to the air bag supporting seats, and the upper part of each of air bag assemblies of both sides is fixedly connected to the longitudinal beam of the car frame through an air bag upper cover plate. The lower part of each of dampers of both sides is fixedly connected to the air bag supporting seats, and the upper part of each of dampers of both sides is fixedly connected with a damper bracket fixed to the longitudinal beam of the car frame. The utility model maintains manipulating stability, enhances ride comfort, overcomes the weakness of the poor side inclination resistance capability of a compound air suspension frame and enhances side inclination rigidity. Thus, the safety of a traveling car is ensured.
Description
[technical field]
The utility model relates to the full air front suspension of super-low floor city bus steeraxle.
[background technology]
Constantly perfect along with developing of automobile industry and arteries of communication, high-grade commercial vehicle/comm..vehicle demand is increasing, and becomes the developing direction of commercial vehicle/comm..vehicle.One of major criterion of high-grade commercial vehicle/comm..vehicle is exactly to adopt air suspension, can improve vehicle running smoothness and traveling comfort like this, makes body platform unloaded constant with the at full load maintenance, and can have " going down on one's knees " function, is convenient to passenger getting on/off.
The sprung parts of domestic production at present is divided into leaf spring suspension and air suspension two big classes, and wherein air suspension can be divided into full air suspension again and become the compound suspension system by leaf spring with the air bag mutual group.
Spring type suspension front suspension structure is by chassis side rail, crossbeam, steel spring and support thereof, shock absorber and upper and lower support thereof are formed, vertical load is all born by leaf spring, so the vibration isolation of system is poor, ride comfort is bad, and empty, at full load overall height changes greatly, i.e. boarding is poor, but anti-roll capability is better than combined type air suspension.
Combined type air front suspension structure is made up of chassis side rail, crossbeam, steel spring and support thereof, air bag and upper and lower bearing thereof, shock absorber and upper and lower support thereof.The vertical load of automobile is carried jointly by leaf spring and air bag, and it is suspended on vibration isolation, the ride comfort than leaf spring and increases, but also has gap with the commercial vehicle/comm..vehicle standard of higher one-level, and its anti-roll capability of spring type suspension descends to some extent relatively.
[summary of the invention]
Technical problem to be solved in the utility model is to overcome existing defective in the above-mentioned prior art, provides a kind of and realize super-low floor, has the all-air suspension mechanism that good ride comfort, road-holding property also can overcome the weakness of combined type air suspension anti-roll capability difference.
The utility model has adopted following technical proposal to solve its technical matters: the full air front suspension of a kind of super-low floor city bus steeraxle, comprise chassis side rail, the crossbeam of captiveing joint and propons with chassis side rail, it is characterized in that: the both sides chassis side rail is arch, and respectively by forward and backward crossbeam captive joint, front cross rail is divided into upper and lower crossbeam, and by the pillar captive joint; Both sides air bag bearing is fixedly connected on the propons two ends by backing plate; Propons middle part captive joint one propelling rod bearing, propelling rod one end of two V-shaped layouts is movably connected on the propelling rod bearing, and the other end is movably connected on the bearing, and this bearing is fixedly connected on the cross sill; Longitudinal rod one end in both sides is movably connected on the air bag bearing, and the other end is movably connected on the vertical propelling rod bearing, and this vertical propelling rod bearing is fixedly connected on the entablatrance; Captive joint with the air bag bearing in air bag assembly bottom, both sides, top is fixedly connected on the chassis side rail by the air bag upper cover plate; Shock absorber bottom, both sides is fixedly connected on the air bag bearing, captives joint with the damper bracket that is fixed on chassis side rail in top.
The utility model is owing to adopted technique scheme, both kept road-holding property, improved ride comfort, overcome the weakness of combined type air suspension anti-roll capability difference again, improved roll rate simultaneously, its anti-roll capability is suitable with the leaf spring suspension, makes the vehicle safety in travelling obtain guarantee.The utility model is applicable to city bus.
