The specific embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail.
The utility model comprises hydro-pneumatic spring 1, hydro-pneumatic spring upper bracket 16 and wheel limit 4, and hydro-pneumatic spring upper bracket 16 is captiveed joint with vehicle frame, and the upper end of oily vapour spring 1 is connected by pin 17 on the hydro-pneumatic spring with hydro-pneumatic spring upper bracket 16.
The utility model also comprises top link 2, following swing arm 5 and swing arm support 12; Wheel 4 upper ends, limit are installed with bulb 3, and the lower end is installed with down bulb 9; The somewhere is connected with the downside pin locknut by hydro-pneumatic spring downside pin 7 between gasoline spring 1 lower end and top link 2 two ends; Top link 2 one ends are connected with the bearing pin nut by top link bearing pin 13 with swing arm support 12, and top link 2 other ends are connected by last bulb 3 with wheel limit 4; One end of following swing arm 5 is connected by following swing arm bearing pin 14 with swing arm support 12, and the other end of following swing arm 5 is connected by following bulb 9 with wheel limit 4.
The utility model also comprises angular transducer 10, sensor fork 8, first sensor bar and second rodmeter; Angular transducer 10 is positioned on the top link bearing pin 13, and with the 13 concentric fixed installations of top link bearing pin; The first sensor bar and second rodmeter are installed as sensor leverage 11 by the screw thread secure alignment.Sensor fork 8 one ends and angular transducer 10 concentric movable installations, the other end is captiveed joint with sensor leverage 11, and the other end of sensor leverage 11 is captiveed joint with hydro-pneumatic spring downside pin 7; Shape in an angle between sensor fork 8 and the sensor leverage 11.Can pass through to regulate the length of thread of the first sensor bar and second rodmeter to satisfy the requirement of assembling.Forming thus with the center of circle of angular transducer 10 is the triangle leverage of centre of gration, and also therefore the angle of sensor fork 8 rotations equals the angle that top link 2 rotates.
The utility model also comprises the limiting stopper 6 and stop screw 15 that is fixedly installed on the swing arm support 12.When top link 2 moved downward certain position, stop screw 15 withstood the lower edge of top link 2, limited its motion.When swing arm instantly 5 moved upward to certain position, limiting stopper 6 withstood down the upper edge of swing arm 5, limited its motion.
The adjusting of chassis frame height is a process relative and ground raises and reduces.Because hydro-pneumatic spring upper bracket 16 is connected with vehicle frame, the upper journal of hydro-pneumatic spring 1 by pin 17 on the hydro-pneumatic spring with after hydro-pneumatic spring upper bracket 16 is connected, it is an integral body that hydro-pneumatic spring 1 connects to ground, and hydro-pneumatic spring extends corresponding vehicle frame and raises, and hydro-pneumatic spring shortens corresponding vehicle frame and reduces.After top link 2, following swing arm 5 and wheel limit 4 are connected by bulb, with swing arm support 12 composition four-bar linkages.When hydro-pneumatic spring shortened, top link 2 raise with respect to vehicle frame, and following swing arm 5 is upward movement thereupon also, thus driven wheel limit 4 upward movement together.Because wheel 4 relative ground, limit maintain static, so vehicle frame moves downward the chassis frame height reduction with respect to ground.Otherwise chassis frame height raises.
There is desirable kinematic relation in top link 2 with the angle and the chassis frame height of horizon.To minimum, middle height value is corresponding one by one with angle from High variation for the corresponding chassis frame height of the positive-angle of this angle from the negative angle of maximum to maximum.Set up the functional relation of this angle and chassis frame height, heighten controller for suspension and convert.Heighten in the process, when top link 2 motion, send signal with top link 2 bonded assembly angular transducers 10 and heighten controller, be converted into chassis frame height numerical value, and the telltale in operator's compartment shows synchronously, can be next step operation of the personnel of heightening foundation is provided to suspension.
