Abstract
The present invention relates to the draft hitch of wheeled car, the particularly a kind of vehicle complex spring equalization suspension device that can realize balanced vibration damping, comprise being arranged on guide arm, accumulator, coil spring and the hydro-pneumatic spring that is hinged mutually with vehicle body on each axletree that characteristics are a cover to be set respectively be linked on the vehicle body by the complex spring support that described coil spring and hydro-pneumatic spring constitute on described each guide arm; The oil cylinder of the hydro-pneumatic spring on the forward and backward wheeled guide arm of homonymy is connected by pipeline, and connects a described accumulator on this pipeline.This draft hitch has improved the cushioning performance of automobile, has the obvious advantage of improving ride comfort when travelling on uneven road surface.
Description
Technical field
The present invention relates to the draft hitch of wheeled car, the particularly a kind of novel draft hitch that can realize balanced vibration damping.
Background technology
In existing automotive suspension structure, a lot of employing spiral spring suspensions are arranged; Also there are some automobiles to adopt hydro pneumatic suspension.Coil spring has advantage of simple structure, but common coil spring is when load change, and the natural frequency of vibration occurring increases the shortcoming that reduces with bodywork height generation marked change with load.Hydro-pneumatic spring has highly controlled advantage, but has strong non-linear (natural frequency of vibration increases with load).Linear coil spring is combined into complex spring with the hydro-pneumatic spring of crossing strong nonlinearity, common carrying, and spring performance of different nature remedies mutually and constitutes the natural frequency of vibration not with the ideal behavior of load change.Usually the pure hydro-pneumatic spring suspension of four-wheel automobile can not be communicated with the hydro-pneumatic spring of front and back the formation equalization suspension, because this structure can not be resisted the trim of vehicle body.
Summary of the invention
The objective of the invention is to propose a kind of later-model vehicle complex spring equalization suspension device,, better improve the cushioning performance of automobile to overcome the defective that existing automotive suspension structure exists.
Vehicle complex spring equalization suspension device of the present invention, comprise being arranged on guide arm, accumulator, coil spring and the hydro-pneumatic spring that is hinged mutually with vehicle body on each axletree that characteristics are a cover to be set respectively be linked on the vehicle body by the complex spring support that described coil spring and hydro-pneumatic spring parallel connection constitute on described each guide arm; The oil cylinder of the hydro-pneumatic spring on the forward and backward wheeled guide arm of homonymy is connected by pipeline, and connects a described accumulator on this pipeline.
Described every cover complex spring, be fixed pallet once in the bottom of its hydro-pneumatic spring, its coil spring is seated on this time pallet, and helical spring upper end is connected with top tray, and top tray is by piston rod and the vehicle body formation flexible-disc joint of rubber cushion blocks with hydro-pneumatic spring.
Also connect a height control system on the pipeline of the hydro-pneumatic spring oil cylinder on the forward and backward wheeled guide arm of described connection homonymy, this height control system is made up of fuel tank, the oil pump that is connected with fuel tank, the height-control valve that is connected with oil pump.
This complex spring suspension system, its each wheel all is equipped with a complex spring assembly, and linear spiral spring suspension has with load to be increased and the remarkable shortcoming that descends of the natural frequency of vibration.And non-linear strong excessively hydro-pneumatic spring suspension increases and the remarkable shortcoming that increases of the natural frequency of vibration with load.The common carrying of coil spring and hydro-pneumatic spring is also suitably selected its stiffness parameters, can remedy shortcoming separately, guarantees that suspension system obtains the ideal behavior that the natural frequency of vibration does not change with load change.Because the hydro-pneumatic spring of homonymy front and rear wheel is by pipeline connection, and a shared accumulator; Take turns independently coil spring constitutes the stressed equalization suspension system of pre-and-post equalization with each.The equalization suspension system that this coil spring and hydro-pneumatic spring are compound has the obvious advantage of improving ride comfort when travelling on uneven road surface: when a certain when taking turns the disturbed distortion of suspension, owing to damping oil cylinder in front and back is communicated with the moving impact load that reduces of fluid string; Because of front and back hydro-pneumatic spring equilibrium of pressure, the load of bearing is identical again, thereby reduces the pitching distrubing moment, improves the cushioning performance of automobile.
Because the hydro-pneumatic spring of and arranged on left and right sides is provided with height control system, the not only lifting of may command vehicle body but also the inclination of may command vehicle body.
Description of drawings
Fig. 1 is the structural scheme of mechanism of vehicle complex spring equalization suspension device of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing structure of the present invention is described in further detail.
With reference to Fig. 1, a kind of vehicle complex spring equalization suspension device, comprise being arranged on guide arm 12, accumulator 3, coil spring 1 and the hydro-pneumatic spring 2 that is hinged mutually with vehicle body on each axletree, a cover is set respectively on described each guide arm 12 is linked on the vehicle body by the complex spring support that described coil spring 1 and hydro-pneumatic spring 2 constitute; The oil cylinder of the hydro-pneumatic spring 2 on the forward and backward wheeled guide arm of homonymy is connected by pipeline 4, and connects a described accumulator 3 on this pipeline 4.
Described every cover complex spring, be fixed pallet once 9 in the bottom of its hydro-pneumatic spring 2, its coil spring 1 is seated on this time pallet 9, and the upper end of coil spring 1 is connected with top tray 10, and top tray 10 is by piston rod and the vehicle body formation flexible-disc joint of rubber cushion blocks 11 with hydro-pneumatic spring 2.
Also connect a height control system on the pipeline 4 of hydro-pneumatic spring 2 oil cylinders on the forward and backward wheeled guide arm of described connection homonymy, this height control system is made up of fuel tank 8, the oil pump 6 that is connected with fuel tank 8, the height-control valve 5 that is connected with oil pump 6.7 for being connected the oil return line of 8 of control cock 5 and fuel tanks among the figure.
Be arranged on the height control system of and arranged on left and right sides hydro-pneumatic spring, it can be two independently height-control valves, it also can be the switch valve that a height-control valve adds two independent manipulation left and right sides liftings, with the shared fuel-feed system that constitutes by oil pump, fuel tank, so that the not only lifting of may command vehicle body but also the inclination of may command vehicle body.
