The specific embodiment
As shown in Figure 1, vehicle frame 1 can adopt the body frame structure for automotive of side fork lift truck, in the front part sides of vehicle frame 1, divide the near front wheel drive system 25 and off front wheel drive system 24 are housed, left drive wheel 3 is connected to (Fig. 5) in the near front wheel drive system 25, and right front drive wheel 2 is connected in off front wheel drive system 24.Three-wheel is housed in the middle position, rear portion of vehicle frame 1 and swings rigid suspension 6, trailing wheel 12 is connected to three-wheel and swings in rigid suspension 6 (Fig. 2).For reducing vehicle frame, be out of shape and improve whole vehicle stability, the two ends that swing rigid suspension 6 at three-wheel are symmetrically installed with left cardan wheel 13 and right cardan wheel 11(Fig. 2), when very not smooth on ground, two cardan wheels still can with ground good contact, realized five of bottom of frame and taken turns stable support structure.
Referring to Fig. 5, the near front wheel drive system 25 and off front wheel drive system 24 have included and have driven fire proof motor 19, mechanical-hydraulic composite brakig device 17, rotating disk 20 and retarder 21.In the near front wheel drive system 25, also include the near front wheel steering cylinder 4, (Fig. 1), in off front wheel drive system 24, also include off front wheel steering cylinder 5.The near front wheel drive system 25 and off front wheel drive system 24 are that to drive fire proof motor 19 be power, by retarder 21, drive respectively two front driving wheels to rotate.During braking, mechanical-hydraulic composite brakig device 17 is held motor output shaft 18 tightly, and locking drives fire proof motor 19, thereby realizes the braking of vehicle.
In f-w-d system, adopt horizontal drive wheel mode, be conducive to reduce the height of cargo platform, increase the area of loading platform; The serviceability of fire proof motor is good, and starting operation is steady, and motor is non-maintaining; Adopt turntable structure, can reduce steering effort.Left and right two front driving wheels are all provided with identical rack and pinion drive, or installing connecting rods driving device, respectively the piston rod displacement of front-wheel steering oil cylinder is separately changed into the corner of front driving wheel.Two front-wheel steering oil cylinders, through matching treatment, are associated the oil outlet of one of them steering cylinder and the oil inlet of another oil cylinder, thereby make the displacement of two oil cylinders identical, identical to guarantee the corner of two front driving wheels.
In Fig. 4, trailing wheel 12 is realized rear-axle steering by being installed on the hydraulic steering mechanism 15 on trailing wheel top.
Front-wheel steering oil cylinder in two f-w-d systems forms four-wheel steering control mechanism together with controlling the hydraulic steering mechanism 15 of trailing wheel.When vehicle is during at cross running, two front driving wheels can not turn to, and by trailing wheel 12, are controlled and are turned to, and the deflection angle of trailing wheel 12 feeds back to electric controller, control the differential of two front driving wheels, realize and keeping straight on or turning driving.When longitudinal direction of car travels, after two front driving wheel half-twists, as wheel flutter, trailing wheel 12 longitudinally locks, and two front driving wheel counter-rotation equal angular, are the interior Eight characters or the outer Eight characters turns to.Two front driving wheels and trailing wheel all can independently be realized 180 ° of rotations, corner equal and opposite in direction, opposite direction between two front driving wheels.
As shown in Figure 2, Figure 3, Figure 4, three-wheel swing rigid suspension mechanism 6 comprises left swing arm 9, right swing arm 10, left cardan wheel 13, right cardan wheel 11, deflecting wheel support bracket 16 and hydraulic steering mechanism 15.Left swing arm 9 is connected with vehicle frame 1 by left swing arm bearing pin 7, and left cardan wheel 13 is hinged on the external side end of left swing arm 9, and right swing arm 10 is hinged with the right-hand member of left swing arm 10 by right swing arm bearing pin 8, and right cardan wheel 11 is hinged on the external side end of right swing arm 10.Above left cardan wheel 13, be provided with left limit piece 22, be provided with right limit piece 23 above right cardan wheel 11, when Vehicle Driving Cycle is during in uneven section, left and right limiting stopper is respectively in order to limit the jerk value of left and right cardan wheel.Left and right cardan wheel can adopt and meet all kinds of cardan wheels that vehicle uses.Trailing wheel 12 is arranged on deflecting wheel support bracket 16, and deflecting wheel support bracket 16 is vertically articulated with on right swing arm 10.Explosion-proof potential device 14(Fig. 3 is installed on left swing arm 9), for measuring the rotational angle of trailing wheel 12.Hydraulic steering mechanism 15 is connected to (Fig. 2, Fig. 4) between right swing arm 10 and deflecting wheel support bracket 16, and hydraulic steering mechanism 15 drives deflecting wheel support bracket 16 deflections, and then makes trailing wheel 12 deflections, with this, realizes turning to of vehicle.
When vehicle requires trailing wheel 12 not play steering-effecting, hydraulic steering mechanism 15 can be locked by trailing wheel 12.Two limiting stoppers are arranged in the top of two cardan wheels, and when vehicle is beated through uneven road surface, both sides cardan wheel, two limiting stoppers can limit beating of both sides cardan wheel.
Three-wheel swings rigid suspension 6 makes the ratio of the adhesive ability on trailing wheel 12 be greater than the ratio of the adhesive ability of left and right two cardan wheels, has improved thus the turning efficiency of vehicle.When Vehicular turn, trailing wheel 12 drives left and right two cardan wheels to turn to, and two cardan wheels do not affect the cornering properties of trailing wheel.The three-wheel arrangement structure of left and right cardan wheel and trailing wheel, has increased the Area of bearing of vehicle, and while having guaranteed to travel on roughness pavement, five take turns simultaneously and land, and have improved thus the stability of Vehicle Driving Cycle.
