Abstract

The invention belongs to the design of the vehicle of road running such as automobile, make and the repacking industry.The invention provides the centnifugal force that the vehicle that utilizes road running produces and the pressure that changes or add power in addition and will hinder automatically away from the car body of turn radius center one side and reduce or raise the method that the opposite side car body is reduced automatically when turning, the center of gravity of vehicle is moved to the turn radius center, producing centripetal force is convenient to turn, can avoid Ackermann steer angle to overturn, guarantee the safety of occupant and goods transport, vehicle ' is not slowed down to the turning or few the deceleration, the energy saving fuel improves conveying efficiency.

Description

The invention belongs to design, manufacturing and the repacking industry of the vehicle that on highway, travels.

The data of the vehicle that on the applicant consults both at home and abroad about highways such as automobile, trac., trailers, travels.Observe vehicle homemade, import, all the record and the application example of no this item technology.

Existing various vehicle travels transfer when curved on highway, car body is away from turn radius center one side (hereinafter to be referred as the outside), because action of centrifugal force, the outside is stressed much larger than the inboard, and out-shift of gravity center causes car body to tilt laterally.If the speed of a motor vehicle is fast, easily cause overturning.

The objective of the invention is to address the above problem, the road vehicles that the anti-obliquity device of automatic car body is housed for manufacturing provides new way.When the anti-obliquity device of car body can be turned in vehicle ' automatically, the Outboard Sections of car body is raised or few the reduction automatically.Simultaneously the body inner side part is reduced automatically, vehicle's center of gravity is moved to the turn radius center, car body just has the horizontal component of force-centripetal force of a gravity, and it is easier that turn inside diameter becomes.The roll-over accident that can avoid the Ackermann steer angle out-shift of gravity center to be caused is guaranteed the transportation safety of occupant and goods, also can increase the speed of Ackermann steer angle, can reach saving fuel, improves the effect of conveying efficiency.

The present invention is when turning in the existing vehicle ', and car body is subjected to action of centrifugal force, and the car body outside is stressed much larger than body inner side, and truck spring is depressed, and makes car body outward-dipping, and causes vehicle's center of gravity to move outward.I think rationally to utilize this stressed power much larger than body inner side in car body outside, by hydraulic oil, stop the outside to descend, transmit the epicoele of pressure to the body inner side hydraulic actuating cylinder, make body inner side that bigger decline be arranged, whole vehicle's center of gravity is moved down, and move to turning center.This way is without additionaling power.If Hydraulic Pump etc. is installed, at Ackermann steer angle, high pressure oil is squeezed into the cavity of resorption of the outer side cylinder of car body, raises outer side body, and high pressure oil is pressed into the epicoele of body inner side oil cylinder simultaneously, side body in reducing, better effects if.

The way of implementing has multiple.Unpowered (no Hydraulic Pump) scheme of talking earlier illustrates the present invention, and (as Fig. 1) fixes a differential type cylinder body 1,3 near the axle housing each wheel of vehicle ... the

piston rod

2,4 of differential type cylinder body ... be fixed on the car body.Connecing the epicoele of differential type cylinder body and the oil pipe of cavity of resorption all receives on the three-position four-way valve 5.Three-position four-way valve 5 horizontal settings.Each spring made the midway location of control stalk in valve body about the control stalk of valve body was used, and this moment, each differential type cylinder body upper and lower cavity communicated with three-position four-way valve, and the accumulation of energy fuel tank of connecting band low pressure.Hydraulic oil is in low-pressure state, is fit to car body this moment and keeps straight on.The differential type cylinder participates in vehicle damping.On three-position four-way valve 5 control stalks scalable weight 6 is housed also, when vehicle is turned with certain speed, control stalk is under the action of centrifugal force of weight 6, the outside of deflection car body, the cavity of resorption that this moment, three-position four-way valve 5 was in oil cylinder 3 only links to each other with the epicoele of oil cylinder 1, and the cavity of resorption of the epicoele of oil cylinder 3 and oil cylinder 1 links to each other with the accumulation of energy fuel tank.Because the Ackermann steer angle outside is stressed big, bonded assembly piston rod 4 will be defeated on the oil in the cavity of resorption of oil cylinder 3 on the car body, and oil flows to the epicoele of oil cylinder 1 from oil cylinder 3 cavity of resorptions.The piston of oil cylinder 1 is descended, drive body inner side by piston rod 2 and descend.The car body outside is descended be obstructed, body inner side descends more, and reaches anti-obliquity purpose automatically.The valve body control stalk is by the springs return midway location when vehicle is kept straight on.The upper and lower cavity of oil cylinder all links to each other with the accumulation of energy fuel tank.U-turn is in like manner no longer narrated.

The scheme that high-pressure hydraulic pump is installed is: when three-position four-way valve mediated, high pressure had circulating system of one's own.Each oil cylinder upper and lower cavity all is in same pressure.Work as Ackermann steer angle, three-position four-way valve control stalk biased outward, this moment, high-pressure hydraulic pump communicated with the cavity of resorption of the outer side cylinder of car body, made on the piston of the outside and moved, and raised the car body outside, and the epicoele of side cylinder is depressed piston in the body that also is open to traffic simultaneously, and body inner side is descended.This scheme is than unpowered scheme better effects if.The available weight of the control of this scheme three-position four-way valve is centrifugal, also available guide's hydraulic pressure (utilizing two side cylinder difference of pressures) mode, also interlocking of signals such as available velocity, direction machine.Available electromagnetic type oil pressure pump, power is from driving engine or electric power.

Every axle of vehicle can be used said apparatus separately, but also multiaxis parallel connection said apparatus.

The speed of a motor vehicle is fast more, and turn radius is more little, moves big more in the vehicle's center of gravity.

Unpowered scheme is applicable to trailer, and vehicles such as lorry are equipped with the scheme of high-pressure hydraulic pump, are applicable to senior vehicles such as car, passenger vehicle, crane.

Automatic car body anti-obliquity device of the present invention can make vehicle keep higher speed when turning, and the energy fuel savings improves conevying efficiency. Can make Ackermann steer angle produce a centripetal force. Turn inside diameter is become easily, avoid or reduce vehicle when turning, overturning, the occupant is felt comfortably cool, guarantee cargo transportation security.
