Abstract
The utility model relates to an increased hydraulically-hoisting universal-wheel steering mechanism for an automobile, which is a mechanism utilizing hoisting universal-wheels to guide direction to turn automobiles, fork trucks, cranes, and particularly semi-dragging trucks. The hoisting universal-wheels are arranged on the first half part of an automobile chassis, the first half part of the automobile is jacked up by the universal-wheels through a hydraulic driving device and replaces the automobile deflection and the direction guidance of the automobile front wheels, under the situation of single braking realized by the driving wheels of the automobile, and the automobile is driven to turn at original place. The turning center of the automobile is positioned on the driving wheel with single braking by the utility model, and thus, the automobile has a small steering radius and a smooth steering even if narrow areas.
Description
The utility model is a kind of with hydraulic lifting cardan wheel guiding, can make the particularly mechanism that turns on the spot of semi-dragging truck of automobile, fork truck, crane.
The automobile that uses generally is to finish handling maneuver with two deflection front-wheel deflection guiding, back-wheel drives now.Automobile is when turning to, the pilot control bearing circle, make each self-deflection different angles (being called angle of inclination) of two deflection front-wheels, deflecting wheel and drive wheel all are on the circumference that one group of concentrically ringed radius do not wait, starting rear drive vehicle then is turning center around one away from the center of circle beyond the automobile position, make circular movement, reach the purpose of motor turning with this.Because deflecting wheel is subjected to the influence of vehicle structure, its angle of inclination generally can not surpass 35 °～45 °, and deflection angle is little, thereby the motor turning radius is big, are subjected to the place limitation big, turn to for automobile on the spot and have brought group difficult.
The purpose of this utility model is exactly on the automobile of this front-wheel deflection guiding, back-wheel drive, set up a kind of universal wheel mechanism by the hydraulic actuator lifting, under the situation of drive wheel one side brake, the turning center of automobile is on the drive wheel position of one side brake, thereby shorten the Turning radius of automobile, reduce the difficulty of motor turning, improve its steering capability.
Task of the present utility model is to finish with following frame mode: the first half lateral symmetry at car chassis is provided with two liftable cardan wheels.Cardan wheel (1) supports with a rocking arm (6), and rocking arm (6) is installed on the bearing (5) that car chassis sets up by a rotating shaft (7).Cardan wheel comes the lifting hydraulic actuator to be made up of several parts such as electrical motor, oil pump, hydraulic actuating cylinder, oil basin, oil pipeline and hydraulic control mechanisms by hydraulic actuator.Hydraulic actuating cylinder (4) is installed near the chassis (3) of cardan wheel (1) by a rotating shaft (10), and stick harness or stopper rod (9) link by a dead axle (8) and rocking arm (6).Electrical motor and oil pump are installed in the place, space of car chassis and the seat bottom of automobile cab.Hydraulic control mechanism is installed in by the indoor hand brake lever of vehicle drive.The hydraulic actuator available motor, also the power of available automotive engine carries out work.When automobile need turn to, earlier fall cardan wheel (1) to kiss the earth with hydraulic actuating cylinder (4) by hydraulic control mechanism, and cardan wheel (1) is moved along ground by the pressure of stick harness or stopper rod (9), the first half of jack-up automobile disengages automobile deflects front-wheel (2) and ground.At this moment cardan wheel rocking arm (6) is perpendicular to the ground, and cardan wheel is in running order.Under the situation that realizes the drive wheel one side brake, start rear drive vehicle and turn to.The braking left rear wheel, automobile drives forwards promptly pivot stud left, and automobile is to the i.e. pivot stud to the right of rear drive; The braking off hind wheel, automobile drives forwards promptly pivot stud to the right, and automobile is to rear drive pivot stud left then.After motor turning is finished, rise cardan wheel by hydraulic control mechanism and be stand-by state, automobile deflects front-wheel (2) recovers to contact with ground, and automobile can travel as usual.
The utility model replaces deflection front-wheel guiding because the cardan wheel with any angle of inclination has been installed on automobile, under the situation of automobile driving wheel one side brake, the motor turning center is on the drive wheel position of one side brake, shortened the Turning radius of automobile greatly, make automobile AT STATION, harbour, warehouse, goods heap limited ground, place such as field and can turn on the spot, particularly make need bigger Turning radius semi-dragging truck turn on the spot and become a reality.Reduce the difficulty of motor turning, improved the steering capability of automobile.According to the analogue test of doing on liberation CA15 type automobile (bicycle), the minimum turning radius of automobile before the utility model is installed is 8.9 meters, minimum turning radius behind installation the utility model shortens to 4.5 meters, only is 1/2 of former minimum turning radius.
Following accompanying drawing has been described an embodiment of the present utility model.
Fig. 1 is a cardan wheel stand-by state scheme drawing.
Fig. 2 is the cardan wheel working state schematic representation.
Fig. 3 installs the scheme drawing that turns to behind the utility model for automobile.
Among the figure: (1) is cardan wheel, (2) automobile deflects front-wheel, (3) car chassis, (4) hydraulic actuating cylinder, (5) bearing, (6) rocking arm, (7) rotating shaft, (8) dead axle, (9) stick harness, (10) rotating shaft, L is a vehicle wheel base, B two-wheeled stub centre distance, α, the angle of inclination of the inside and outside wheel of β, O are the turning center before automobile is installed the utility model, and P is the turning center behind installation the utility model, R is the Turning radius before automobile is installed the utility model, and H is the Turning radius after automobile is installed the utility model.
The utility model is installed on the liberation CA15 type automobile (bicycle), cardan wheel (1) is installed in deflection front-wheel inboard by rocking arm (6), the modulated pressure steering unit makes cardan wheel (1) drop to kiss the earth and jack-up automobile first half, automobile deflects front-wheel (2) and ground are disengaged, at this moment cardan wheel rocking arm (6) is perpendicular to the ground, cardan wheel is in running order, drive trailing wheel realizes under the situation of one side brake on a left side, automobile drives and advances, and realizes pivot stud left.
Claims (3)
1. set up on the automobile of two deflection front-wheel guiding, back-wheel drive for one kind, be used for the mechanism that automobile turns on the spot, it is characterized in that it is made up of liftable cardan wheel and hydraulic actuator.
2. according to the described mechanism of claim 1, it is characterized in that the liftable cardan wheel is installed in the first half of car chassis.
3. according to the described mechanism of claim 1, it is characterized in that hydraulic actuating cylinder is installed near the chassis of cardan wheel, electrical motor, oil pump are installed in the position, space on chassis and the seat bottom of automobile cab, and hydraulic control mechanism is installed in by the indoor hand brake lever of vehicle drive.
