Description
[technical field]
The utility model relates to the rear overhang shelf structure, the full air rear suspension of particularly a kind of automobile drive axle structure.
[background technology]
Constantly perfect along with developing of automobile industry and arteries of communication, high-grade commercial vehicle/comm..vehicle demand is increasing, 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.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 and compound suspension (suspension system that is become with the air bag mutual group by leaf spring) again.
Spring type suspension rear 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 rear 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.
Because left and right wheel of dependent suspension is connected on the same axis, can not link to each other with vehicle frame (or vehicle body) by suspension separately.Therefore exist nonspring carried mass big, its suspension impact load suffered and that pass to vehicle body is big; Body vibrations frequency height, riding comfort is low; And because the beating together of left and right wheels, the inclination of vehicle body and Oscillation Amplitude such as will strengthen at defective.The ride comfort of vehicle can not fully guarantee under to the operating mode of running at high speed.
[summary of the invention]
The problem that the utility model need solve is exactly that a kind of all-air suspension mechanism that has good ride comfort, cargo transportation security, road-holding property and can overcome the weakness of combined type air suspension anti-roll capability difference will be provided.
The utility model has adopted following technical proposal to solve its technical matters: the full air rear suspension of a kind of automobile drive axle structure, comprise vehicle frame, back axle and the wheel hub that is rotationally connected with back axle, it is characterized in that: the back axle two ends are captive joint both sides arched beam respectively, and forms a H ellbeam under vehicle frame; The middle part of back axle is fixedly equipped with a propelling rod bearing, and the bottom of a V-type propelling rod is connected on the propelling rod bearing, and these V-type propelling rod two tops are connected with the bearing that is fixed on the vehicle frame inboard; One end of and arranged on left and right sides longitudinal rod is connected the middle part of both sides arched beam, and its other end is connected the lower end of longitudinal thrust shaft bar, and the upper end of this longitudinal thrust shaft bar is fixedly connected on the anterior outside of vehicle frame; One Panhard rod is the U type, and its two ends are connected suspension rod lower end, both sides, and this suspension rod upper end is fixedly connected on the rear outside of vehicle frame by the stabilizer rod carriage; The U-bottom portion both sides of stabilizer rod are rotationally connected with stabilizer rod clamping plate bearing respectively, and this stabilizer rod clamping plate bearing is separately fixed on the arched beam of both sides; The two ends of arched beam are fixedly equipped with two air bags respectively, captive joint with the outside of vehicle frame by the air bag upper cover plate in this air bag top; Captive joint one shock absorber of every side arched beam, the upper end of this shock absorber are fixedly connected on one and are fixed on the damper bracket in the vehicle frame outside.
The utility model is owing to adopted technique scheme, both kept road-holding property, improved cargo transportation security, 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 the rear suspension of heavy-duty truck.
