Abstract

The utility model relates to an improved suspension frame for motor vehicles. The utility model is characterized in that the suspension frame is composed of a vibration damper; the vibration damper is four double-action differential oil cylinders which are hinged between a vehicle frame and a vehicle shaft; a cavity A and a cavity B of the differential cylinder are communicated with an oil pump, an energy storage device, a pressure relay, a check valve, and an electromagnetic unloading overflow valve through a double oil pipe and a controller. When the vehicle turns, or slantwise inclines, runs on the cavity pavement, and brakes, the double-action differential cylinder and the suspension frame can regulate the vehicle body. The running performance and the throughput capacity of the vehicle are improved, and the vehicle loss and the maintenance cost are reduced.

Description

A kind of suspension of power actuated vehicle

The utility model relates to the suspension of power actuated vehicle.

Suspension is the vehicle frame of power actuated vehicle or the power transmission connecting device between self-supporting body and forward and backward vehicle bridge or the wheel.Vehicle under steam, the road surface acts on supporting power, tractive force, braking force and the lateral reaction on the wheel and moment that these counter-forces caused all will be delivered on vehicle frame or the self-supporting body by suspension, to guarantee the cruising of automobile.Mostly system is stiff for the suspension of existing power actuated vehicle, the then buffer distance that has is not enough, cause vehicle potted road surface because of intense impact, rock and spring plate fracture, sudden and violent tire, bad steel ring, spindle nose take place, twist into two parts semiaxis or phenomenons such as crossbeam torsional deflection and brake instability.

The purpose of this utility model is exactly a kind of rideability that can improve power actuated vehicle will be provided, improve it at abominable ground-surface carrying capacity, the both suspension of safety and failure-free power actuated vehicle.

For finishing the suspension of goal of the invention design-calculated power actuated vehicle, form by the elastic element and the shock absorber that are installed between vehicle frame and the forward and backward vehicle bridge, elastic element can be steel spring, coil spring, torsion bar spring, gas spring or rubber spring, and shock absorber is four double acting differential cylinders, and cylinder rod and axletree are hinged; Oil pump by drive power source links to each other with controller with oil pipe through boiler check valve, link to each other with four double acting differential cylinders through the two-way oil pipe again, wherein a road binders pipe communicates with the A chamber of vehicle right side two double acting differential cylinders and the B chamber of vehicle left side two double acting differential cylinders, another road binders pipe communicates with the B chamber of vehicle right side two double acting differential cylinders and the A chamber of vehicle left side two double acting differential cylinders, boiler check valve also links to each other with pressure relay, compression indicator, on the oil pipe between boiler check valve and the controller and be connected with energy storage and electromagnetism unloading overflow valve.On the lengthening vehicle, controller can be two or more.

The power actuated vehicle that the utility model suspension is installed is when straight-line travelling, four double acting differential cylinders are made the power-assisted shock absorber and are used, its stiffness can arbitrarily be adjusted, and can guarantee all the time that suspension has enough buffer distances and crack, ground, and vehicle is by bend or when the skew back road traveling, vehicle body can tilt automatically to the inside by the oil circuit release of suspension; And vehicle is when skew back or potted road surface travel, the oil pressure of four double acting differential cylinders by the increase and decrease suspension, and the may command vehicle body is travelling near under the horizontal state; And vehicle by the adjusting of suspension, can increase the adhesive ability of tire road pavement when brake, shortens the positive braking distance.Simple, the compact conformation of this suspension technology is applicable to various power actuated vehicles, makes that vehicle ' is more steady, comfortable, safety.

Embodiment describes the utility model below in conjunction with accompanying drawing.

Fig. 1 is the structural representation of the suspension of the utility model power actuated vehicle.

As shown in Figure 1, the upper articulation of four double acting differential cylinders 13,16,17,18 on the preceding right side of the vehicle frame 12 of power actuated vehicle, a preceding left side, right, the Hou Zuochu in back, the cylinder rod of oil cylinder and axletree 14 are hinged.The oil pump 5 that drives by propulsion source 6 oil suction and link to each other with controller 10 from fuel tank 9 through boiler check valve 4.Pressure can be through boiler check valve 4, and is stored in the accumulator 1 after relay 3 is adjusted, and its pressure is shown by compression indicator 2.Communicate with controller 10 by oil pipe again, communicate with 15 fens two-way and four double acting differential cylinders 13 by oil pipe 12 again.Be connected with electromagnetism unloading overflow valve 8 between boiler check valve 4 and the controller 10.When vehicle by bend or at the skew back road traveling, during as turnon left, controller 10 makes two use the A chamber of differential cylinder 18 and 17 and the B chamber releases of double acting differential cylinder 13 and 16 by oil pipe 15 and 11, vehicle body skew back to the inside naturally then, make in the vehicle's center of gravity and move, to resist the safety hazard that centnifugal force was brought, the angle of the high more skew back to the inside of the speed of a motor vehicle is big more; And when vehicle when skew back or potted road surface travel, increase the oil pressure of oil pipe 15 and 11 by controller 10, double acting differential cylinder 13,16,17,18 control vehicle bodies are being travelled near under the horizontal state, thereby the automatic guidance vehicle travel in left and right sides skew back amplitude 2.5 degree.

Claims

1, a kind of suspension of power actuated vehicle, by be installed in vehicle frame with before, elastic element between the back vehicle bridge and shock absorber are formed, it is characterized in that said shock absorber is four double acting differential cylinders, cylinder rod and axletree are hinged, oil pump by drive power source links to each other with controller with oil pipe through boiler check valve, link to each other with four double acting differential cylinders through the two-way oil pipe again, wherein a road binders pipe communicates with the A chamber of vehicle right side two double acting differential cylinders and the B chamber of vehicle left side two double acting differential cylinders, another road binders pipe communicates with the B chamber of vehicle right side two double acting differential cylinders and the A chamber of vehicle left side two double acting differential cylinders, boiler check valve also with pressure relay, compression indicator links to each other, on the oil pipe between boiler check valve and the controller and be connected with energy storage and electromagnetism unloading overflow valve.

2, the suspension of power actuated vehicle according to claim 1 is characterized in that said controller can be more than two.
