Abstract
The utility model discloses an in-situ steering device for motor vehicle. The utility model makes use of the principle of hydraulic technique to solve the steering problem of the motor vehicle. The in-situ steering device for motor vehicle can do clockwise and anticlockwise rotating motions on the horizontal direction within the range of 360 DEG. The driving direction of the motor vehicle can be changed quickly. The utility model is characterized in that the vehicle is lifted by a hydraulic cylinder. The rotation is driven by a low speed high torque hydraulic motor. The utility model can automatically turn the head with the operation of the driver on a crowding road. So the maneuverability of the vehicle is improved, and the in-situ turning gear can be used as a carriage jack. The in-situ turning gear for motor vehicles is appropriate for cars, lorries, engineering vehicles, tanks, other military vehicles, etc. The in-situ turning gear for motor vehicles has the advantages of simple structure, reliable working, flexible operating, low cost, and easy maintenance.
Description
The utility model belongs to and relates to power actuated vehicle and turn to technology to rely on the hydraulic technique device specifically.
Existing power actuated vehicle travels and can only advance or move backward as fore-and-aft direction, or utilize reverse action just can make head end operation, thereby need certain space for activities, can not make pivot stud, during as narrow road surface or vehicle congested conditions, just vehicle is in the advance and retreat state of all There ising nothing one can do.
The purpose of this utility model just is to solve power actuated vehicle in the urban traffic congestion, on the highway that vehicle is concentrated again on the inconvenient passage of reversing end for end or the mountain area is narrow, use the utility model just can on 360 ° of horizontal directions of the liftoff work in original place, rotate the tune action, increase the new function and the manoevreability of power actuated vehicle with this.Solve unsolved problem in the reality technology.
The utility model is to use hydraulic principle, hydraulic gear is installed on the power actuated vehicle roman rigid chassis, utilize driving engine to become a maneuvering system for power combines with hydraulic efficiency pressure system, by driver operation, the occupant need not to get off and can make vehicle change travel direction in the original place.
By accompanying drawing the embodiment that the utility model uses is described below on small passenger car:
Accompanying drawing 1, hydraulic scheme of the present utility model
Accompanying drawing 2, round lifting of the present utility model turn to supporting station longitudinal profile scheme drawing.
Fig. 1, after vehicle stops to travel, provide power with vehicle motor to Hydraulic Pump (2), it through filter (1) becomes high-voltage oil liquid after the sucking-off with fluid and flows to whole hydraulic efficiency pressure systems from fuel tank.Want to make head end operation to turn to, the valve rod of at first handling parallel series change-over valve (4-2) moves right and makes it that high-voltage oil liquid is transferred to the hydraulic actuating cylinder (7) that passes vehicle drain pan (17) and consult Fig. 2, in the 160-200 kilograms per centimeter
2Applied pressure promote down piston (19) reach lower dead point with garden type lifting turn to supporting station (9) move downwards until contact with ground and gradually vehicle lifting is made its four when failing the unsettled 100-200 of reaching millimeter or higher height till.Reply meta with the valve rod of parallel series change-over valve (4-2) this moment.After vehicle stops lifting, press the valve rod of the mobile again parallel series change-over valve of direction (4-1) of head end operation then, switch high-pressure oil passage, make it to drive low speed high torque hydraulic motor (10) running that is installed on the vehicle chassis frame (22).
Fig. 2, when turning round, HM Hydraulic Motor drives driving gear (11) rotation, meanwhile with its ingear, and with bolt (21) be welded on the driven gear (8) that turns to that adapter plate (18) on the weight of chassis frame (22) fits together and rotate, can make vehicle with 3 rev/mins～10 rev/mins rotating speed in 360 ° scope, in the horizontal direction, make contrary, right-hand revolution.Be that the level that vehicle can be made any angle turns to.Square opening on the piston rod (20) allows vehicular drive main shaft (23) to pass, phase mutual interference when avoiding work, piston rod (20) will with thrust bearing (25), cylindrical bearing (24), round lifting turns to the hub cap (9a) of supporting station, ball (27) and circular lifting turn to the base (9b) of supporting station to fit together, buy car in installments and make handling maneuver, turn to the face of changing one's position of supporting station all adoring four track adjusting wheels (26) all around in circular lifting, tilt to keep the unlikely when rotated generation of vehicle.Circular lifting turns to the hub cap (9a) on the supporting station that two guide pillars (28) are housed, and moves automatically with anti-vehicle.Consult Fig. 1, Fig. 2, when head end operation turns to arrival to give the angle of phase, make the valve rod of parallel series change-over valve (4-1) reply meta, vehicle shuts down, and then the valve rod of parallel series change-over valve (4-2) is moved to the left, the high-voltage oil liquid oil return in the hydraulic efficiency pressure system, piston in the promotion hydraulic actuating cylinder (7) moves up and reaches first dead center, in order to circular lifting is turned to supporting station withdrawal, the four-wheel of vehicle is landed once again after, even the direction that turns to according to tune with vehicle continues to travel.
Fig. 1 is provided with bidirectional hydraulic lock (6) at hydraulic actuating cylinder (7) import and export, its function be when vehicle reached by lifting give the phase position after tight locking oil circuit, sink after lifting to prevent vehicle.In like manner during vehicle ' because oil circuit also is to be in the circular lifting that locking state withdrawn to turn to supporting station also can not sink, to guarantee vehicle driving safety.Limit valve (5) is in order to the position and the double as unloader valve at the upper and lower dead point of piston arrives in the restriction oil cylinder.
In the loop of low speed high torque hydraulic motor, be provided with slow supply oil valve (12), when impacting with high pressure and repairing in oil circuit appear in preventing in a flash of stopping operating of vehicle in the oil circuit, also can make HM Hydraulic Motor that brake function is arranged simultaneously.Balance cock (13) is in order to the rotating speed of regulator solution pressure motor.
In hydraulic efficiency pressure system, be provided with back pressure valve (14) and be used for laying in certain oil pressure, replenish fluid for power element.Filter (15) filters fluid once more, to keep the cleaning of fluid.Safety valve (16) is the safety that is used for guaranteeing whole hydraulic efficiency pressure system.
Device of the present utility model is installed on the chassis of motor vehicles, and draws close with the center of gravity of vehicle as far as possible, and the series connection reversal valve control crank place near the driver's seat, on the easy to operate position. Cooperate vehicle to reverse gear and use the mobility that just can increase vehicle, the jack that also can double as vehicle uses.
The utility model is used for car, offroad vehicle, truck, big minibus and various engineering truck, more be applicable on the military vehicle such as tank, armored personnel carrier, self-propelled gun, two tenon battlebuses etc., can concentrate in emergency circumstances crowded, evacuate rapidly vehicle and spread from dangerous situation.
The utility model is simple in structure, reliable operation, and flexible movements, with low cost, easy to operate, for ease of maintenaince.
