Detailed description of the invention
As Fig. 1, 2, 3, shown in 6, this device comprises rear wheel support, vehicle body support plate, recoil spring, pulley support, pulley, slide block shifting bar, chute, drive hydraulic actuating cylinder, hydraulic actuating cylinder fixed sturcture, rear wheel, trailing wheel rotating shaft, leaf spring, sleeve fixed block, slide block guide rail, slide block, wherein rear wheel is arranged on trailing wheel rotating shaft side, middle, leaf spring convex side is fixed in trailing wheel rotating shaft, two ends, leaf spring recessed side are fixed on rear wheel support, rear wheel support forms two bottoms by forming both sides, a top in the middle of four 90 degree of bendings, the available space making full use of wheel both sides is mainly wanted in this design, and be convenient to the installation of shock absorber, as shown in Fig. 4,5,8, slide block is arranged on by its bottom chute on the guide rail that is fixed on rear wheel support top end face, and moves along guide rail direction, pulley is arranged in pulley support, pulley slides in slide block end face groove, pulley support has two and is equidistantly arranged in the body support base surface area corresponding to rear wheel support apex zone, the corresponding pulley of each pulley support and slide block, two groups of slide blocks, what the design goal of pulley and pulley fixing structure was that rear wheel support energy both sides balance supports vehicle body, slide block shifting bar two ends are arranged on the side of two slide blocks respectively, and one end and driving hydraulic actuating cylinder one end are connected and fixed, the hydraulic actuating cylinder other end is connected with the hydraulic actuating cylinder fixed sturcture be fixed on side, rear wheel support top, moved by Driven by Hydraulic Cylinder slide block shifting bar, the cooperation position change of pulley and slide block top chute, the usable height of slider support changes, when usable height reduces, recoil spring will be stressed, at this moment certain auxiliary buffer action will be played, in addition when not needing recoil spring to assist buffering, hydraulic actuating cylinder is driven to play the effect of fixing slide position, pulley is allowed to be in a certain position on the chute of slide block top, at this moment the complete backup plate spring buffering of trailing wheel, as shown in Figure 7,8, for in two bottoms of rear wheel support both sides any one, sleeve fixed sturcture one end is fixed on rear wheel support bottom, the other end be fixed on be arranged on vehicle body support plate bottom surface sleeve fixed block on, recoil spring one end is arranged on rear wheel support bottom, the other end is arranged on vehicle body support plate bottom surface and is nested in outside sleeve fixed sturcture, is provided with tube-in-tube structure in recoil spring inside, and object utilizes tube-in-tube structure to fix cross travel between vehicle body support plate and rear wheel support.
As shown in Figure 1, drive hydraulic actuating cylinder, hydraulic pipe, on Hydraulic Pump, front wheel sensor once connects, under generally running into emergency case, the road surface that front-wheel can be felt very large in advance rises and falls, and the front-wheel utilizing front-wheel to sense rises and falls and regulates the damping device of trailing wheel.
As shown in Figure 9, described sleeve fixed sturcture comprises bar in sleeve, sleeve outer ring, and in its middle sleeve, bar one end is arranged on sleeve fixed block, and one end, sleeve outer ring is arranged on rear wheel support, and in sleeve, the bar other end is nested with inside, sleeve outer ring.
Described front wheel sensor can be pressure sensor or displacement pickup.When front-wheel runs into the unexpected change on road surface, the pressure jump of front-wheel fulcrum can be there is, or the change in displacement of front-wheel leaf spring fulcrum, utilize pressure sensor or displacement pickup to go perception all can obtain the signal of bump change, then act on and assist shock absorption device to trailing wheel, start shock absorber.
As shown in Figure 10, for rear wheel damping device runs rough schematic, for auxiliary shock absorption device, when passenger vehicle is normally in smooth traveling on the broad road, slide block and pulley keep certain cooperation, namely, relative displacement between rear wheel support and vehicle body support plate is constant, recoil spring will not have the change of deformation, at this moment the complete backup plate spring buffering of passenger vehicle trailing wheel, the elasticity modulus of the leaf spring of passenger vehicle is larger, there is when the very little prevailing roadway that rises and falls travels the effect that stable vehicle body rocks, when the extreme running into suddenly road surface is protruding or pit time, due to larger leaf spring elasticity modulus, there is very large unexpected fluctuating in vehicle body, so the design is when the front-wheel that passenger vehicle is first pass by occurs to rise and fall suddenly, signal is communicated to Hydraulic Pump, make to drive hydraulic ram to be moved along guide rail by slide block, at this moment the relative distance of rear wheel support and vehicle body support plate changes, recoil spring generation deformation is stressed, because the effect of recoil spring, when slide block continues mobile, may occur that pulley and slide block disconnect, prop by recoil spring completely, after trailing wheel assists buffer gear to adjust, when trailing wheel runs over projection or pit, because the buffer action of recoil spring, the uncomfortable sensation of vibrations will be reduced, in the design, recoil spring is arranged on rear wheel support two bottom, also be the object for the length increasing recoil spring as much as possible, the length of recoil spring is longer, the elasticity modulus of the recoil spring in corresponding design can be less, cushion characteristic is better, simultaneously because the elasticity modulus of recoil spring is less, if travelling prevailing roadway also in the words of effect, passenger vehicle there will be heave of the sea, so at trailing wheel by after projection, slide block moves, increase the relative distance of rear wheel support and vehicle body support plate, recoil spring is not booster action, at this moment trailing wheel uses the leaf spring that elasticity modulus is large.
