Summary of the invention
The problem existed for above-mentioned prior art, this utility model provides a kind of quarry tipper dual-pulling rod type McPherson front suspension structure, the ride comfort in running and control stability can be promoted, reduce use cost, extend the life-span of the parts such as suspension, vehicle frame, tire, thus improve the overall performance of mine truck.
To achieve these goals, a kind of quarry tipper dual-pulling rod type McPherson front suspension structure that this utility model uses, including drag link, brace, hydro pneumatic suspension cylinder barrel and the hydro pneumatic suspension piston rod being arranged in hydro pneumatic suspension cylinder barrel, drag link one end is connected with vehicle frame with bearing pin assembly II by oscillating bearing II, and the other end is connected with hydro pneumatic suspension piston-rod lower end by oscillating bearing；One end of brace is connected with vehicle frame with bearing pin assembly III by oscillating bearing III, and the other end is connected with hydro pneumatic suspension piston-rod lower end by oscillating bearing；The upper-lower position of drag link and brace can be adjusted according to practical situation；Hydro pneumatic suspension cylinder barrel and hydro pneumatic suspension piston rod composition hydro pneumatic suspension oil cylinder, be connected with vehicle frame with bearing pin assembly I by the oscillating bearing I of hydro pneumatic suspension cylinder barrel upper end.It is filled with fluid and air in hydro pneumatic suspension cylinder, and fluid and AIR Proportional can be changed according to actual application environment, thus realize nonlinear stiffness characteristic and the nonlinear dampling characteristic of suspension, be conducive to the ride comfort improving mine car on different road surfaces.
Described hydro pneumatic suspension piston rod is connected with drag link by oscillating bearing IV, and hydro pneumatic suspension piston rod is connected with brace by oscillating bearing V.The oil cylinder of existing candle type suspension bears whole power and moment, and stress is complicated, and the oil cylinder life-span is low.In this utility model, drag link and the existence of brace, bear the most power of suspension and moment, improve the mechanical characteristic of suspension oil cylinder, improve the service life of oil cylinder, and ride comfort is more preferable.
By the length of two pull bars of appropriate design, hydro pneumatic suspension characteristic, guarantee quarry tipper is when loaded vehicle position, and drag link is horizontal and along lateral direction of car, thus ensures under severe duty, front tread change minimum, while improving riding stability, tire wear is minimum.The positional parameter of candle type suspension, as front-wheel camber, kingpin inclination, castor do not change in vehicle operation, this is disadvantageous to the vehicle kinematics characteristic in travelling.Dual-pulling rod type McPherson front suspension structure of the present utility model, the two ends of drag link and brace are oscillating bearing and connect, can swing up and down along with the flexible of suspension oil cylinder, by optimizing drag link, the pin joint position of brace is capable of in vehicle operation, especially during turn inside diameter, the positional parameter making suspension changes according to the rule of beneficially vehicle dynamics characteristics, improves the manipulation stability of vehicle.
Compared with prior art, this utility model solves the problem that general mine vehicle oil-gas suspension load-up condition is severe, reduces hydro pneumatic suspension peak stress, reduces abrasion, improves hydro pneumatic suspension service life；Being joined directly together with hydro pneumatic suspension piston rod by two connecting rods, simple in construction, Front wheel Alignment Parameters Changing Pattern is preferable simultaneously, improves control stability and the riding comfort of mine truck, and Life of Tyre is also improved；Each connecting rod two ends are oscillating bearing and connect, and each connecting rod Impact direction is along two ends oscillating bearing centre of sphere line and influences each other little, reduce the change of structural member Impact direction and the Deformation mode such as vehicle frame, and meanwhile, bar linkage structure is simple, and installation, maintenance is very convenient.

Detailed description of the invention
The utility model is described in further detail below in conjunction with the accompanying drawings.
As shown in Figure 1, a kind of quarry tipper dual-pulling rod type McPherson front suspension structure, including drag link 4, brace 12, hydro pneumatic suspension cylinder barrel 3 and the hydro pneumatic suspension piston rod 9 being arranged in hydro pneumatic suspension cylinder barrel 3, drag link 4 one end is connected with vehicle frame with bearing pin assembly II5 by oscillating bearing II6, and the other end is connected with hydro pneumatic suspension piston rod 9 lower end by oscillating bearing；One end of brace 12 is connected with vehicle frame with bearing pin assembly III10 by oscillating bearing III11, and the other end is connected with hydro pneumatic suspension piston rod 9 lower end by oscillating bearing；The upper-lower position of drag link 4 and brace 12 can be adjusted according to practical situation；Hydro pneumatic suspension cylinder barrel 3 is connected with vehicle frame with bearing pin assembly I2 by the oscillating bearing I1 of hydro pneumatic suspension cylinder barrel 3 upper end with hydro pneumatic suspension piston rod 9.
Hydro pneumatic suspension piston rod 9 connects by oscillating bearing IV7 and oscillating bearing V8 is corresponding with drag link 4 and brace 12 respectively.
During use, by the length of two pull bars of appropriate design, hydro pneumatic suspension characteristic, it is ensured that quarry tipper is when loaded vehicle position, drag link is horizontal and along lateral direction of car, thus ensureing under severe duty, front tread change minimum, while improving riding stability, tire wear is minimum.The positional parameter of candle type suspension, as front-wheel camber, kingpin inclination, castor do not change in vehicle operation, this is disadvantageous to the vehicle kinematics characteristic in travelling.Dual-pulling rod type McPherson front suspension structure of the present utility model, the two ends of drag link and brace are oscillating bearing and connect, can swing up and down along with the flexible of suspension oil cylinder, by optimizing drag link, the pin joint position of brace is capable of in vehicle operation, especially during turn inside diameter, the positional parameter making suspension changes according to the rule of beneficially vehicle dynamics characteristics, improves the manipulation stability of vehicle.
It is filled with fluid and air in the hydro pneumatic suspension cylinder that hydro pneumatic suspension piston rod (9) in hydro pneumatic suspension cylinder barrel (3) forms, and fluid and AIR Proportional can be changed according to actual application environment, thus realize nonlinear stiffness characteristic and the nonlinear dampling characteristic of suspension, be conducive to the ride comfort improving mine car on different road surfaces；Wherein air also can be replaced nitrogen.
