The specific embodiment
Contrast accompanying drawing below, by the description to optimum embodiment, the specific embodiment of the present utility model is described in further detail.
As shown in Figures 1 to 4, the narrow body automobile of track rear that this is adjustable, comprises vehicle frame 1, at vehicle frame 1 front end, establishes front-wheel and the front-wheel steering driver train being connected with front-wheel, in vehicle frame 1 both sides, rear end, is respectively equipped with trailing wheel 13, and trailing wheel 13 is connected with vehicle frame 1 by wheel tread adjusting mechanism.
Wheel tread adjusting mechanism comprises crossbeam, longeron and is located at the hydraulic actuating cylinder 3 on vehicle frame; Crossbeam and longeron one end interconnect, longeron other end connecting vehicle frame 1, and the crossbeam other end connects wheel 13; On longeron, being provided with the piston push rod 4 that pushes away groove 12 and hydraulic actuating cylinder 3 is connected; On crossbeam and longeron, be provided with the reversible ratchet device 11 matching.
On vehicle frame 1, be provided with the electric hydraulic pump 2 of connecting fluid cylinder pressure 3.
Longeron one end and vehicle frame 1 are hinged, and the longeron other end and crossbeam are hinged.
On piston push rod 4, establish penetrate push away groove 12 when piston push rod 4 is flexible at the push rod pin 5 that pushes away groove 12 interior movements.
Preferably push away groove 12 for being located at the kidney slot on longeron.
As shown in Figure 5 to Figure 6, wheel tread adjusting mechanism comprises that symmetry is located at the revolver distance regulating mechanism of connecting vehicle frame rear end left side wheel and the right wheel tread adjusting mechanism of connecting vehicle frame rear end right side wheels of vehicle frame 1 both sides.Revolver distance regulating mechanism and right wheel tread adjusting mechanism, include the connecting rod mechanism that crossbeam, longeron, reversible ratchet device 11 and piston push rod 4 connect and compose.
Revolver distance regulating mechanism, comprises left longeron 8, left crossbeam 7, reversible ratchet device 11 and hydraulic actuating cylinder 3; Right wheel tread adjusting mechanism, comprises right vertical beam 10, right crossbeam 9, reversible ratchet device 11 and hydraulic actuating cylinder 3.The leading portion of left longeron 8 and right vertical beam 10 is connected with vehicle frame 1 by selling 6 before longeron respectively, and the rear end of left longeron 8 and right vertical beam 10 is connected with the front end of right crossbeam 9 with left crossbeam 7 by selling 14 after longeron respectively.The rear end of left crossbeam 7 and right crossbeam 9 is connected with trailing wheel 13.Hydraulic actuating cylinder 3 is connected on vehicle frame 1, and the front end of piston push rod 4 is connected with the groove 12 that pushes away on right vertical beam 10 with left longeron 8 by two push rod pins 5.
Electric hydraulic pump 2 is by controlling piston push rod 4 flexible of hydraulic actuating cylinder 3, the push rod pin 5 that makes piston push rod 4 front ends left swing leg longeron 8 and right swinging kick longeron 10 push away groove 12 in move, thereby left swing leg longeron 8 and right swinging kick longeron 10 are rotated sell 6 before longeron centered by, reach the effect that changes track rear.
As Fig. 7 and Fig. 8, reversible ratchet device 11 changes by the angle of controlling between left longeron 8 and right vertical beam 10 and left crossbeam 7 and right crossbeam 9, thereby reaches the effect that changes trailing wheel angle.
Narrow body automobile is to overtake time, reversible ratchet device 11 is by controlling the increase of angle between left longeron 8 and right vertical beam 10 and left crossbeam 7 and right crossbeam 9, the rear end of left crossbeam 7 and right crossbeam 9 is connected trailing wheel 13, makes trailing wheel 13 in to overtake, produce the external force of travelling laterally; Electric hydraulic pump 2 makes the elongation of the piston push rod 4 of hydraulic actuating cylinder 3 by control, left longeron 8 and right vertical beam 10 are outwards rotated under the effect of piston push rod 4 centered by longeron front axle 6, thereby reach by the effect of hydraulic actuating cylinder 3 and reversible ratchet device 11 object that increases track rear.
The narrow body automobile of track rear that this is adjustable, when automobile driving speed surpasses certain value, electric hydraulic pump 2 is by the elongation of control plunger push rod 4, and longeron moves under piston push rod 4 drives, and turning ratchet drives ratchet and then promotes cross beam movement; Reversible ratchet device 11 is controlled the increase of longitudinal and cross beam angle, and track rear is extended, and automobile forces trailing wheel 13 outwards to travel in to overtake; When track rear increases to setting value, piston push rod 4 stops extending, and reversible ratchet device 11 keeps to overtake trailing wheel 13 by adjusting the angle of trailing wheel 13.
When running into narrow road section and maybe need to stop, automobile is first reduced to certain value by speed, and electric hydraulic pump 2 is by the contraction of control plunger push rod 4, and reversible ratchet overturns, longeron moves under piston push rod 4 drives, and turning ratchet drives ratchet and then promotes cross beam movement; Reducing of the angle of reversible ratchet device 11 control longitudinal and cross beams, track rear reduces, and automobile forces trailing wheel 13 inwardly to travel in to overtake; When track rear narrows down to minimum value, piston push rod 4 stops shrinking, and reversible ratchet device 11 keeps to overtake trailing wheel 13 by adjusting the angle of trailing wheel 13.Compare with existing narrow body automobile, the narrow body automobile of track rear that this is adjustable, track rear can, according to road conditions and the actual adjustment of the speed of a motor vehicle, have better riding stability and safety.
The utility model specific implementation is not subject to the restrictions described above, as long as adopted the improvement of the various unsubstantialities that method of the present utility model design and technical scheme carry out, all within protection domain of the present utility model.
