The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, a kind of non-highway wide dumper offset cab shock absorption device, comprise two bumpers, bumper comprises bumper body 3, upper bracket 2 and undersetting 4, two bumper symmetries are arranged on cab framework 1 both sides, the upper bracket 2 of every side bumper and undersetting 4 are welded on respectively in cab framework 1 and cab legs 10, and bumper body 3 is connected with undersetting 4 with upper bracket 2 by bolt, and bumper body 3 is all acute angle with cab framework 1 and cab legs 10.According to the feature of the narrow and small compactness of side chamber cab space structure, the angle between bumper body 3 and cab framework 1 is preferably to 10 °.Adopt bumper tilting to install, energy fast speed absorbs the vibrational energy of vertical and horizontal direction, can improve the ride comfort of operator's compartment integral body.Be angle between bumper body 3 and cab framework 1 while being 10 °, the integral structure matching of vibration insulating system is good, and damping effect is the most obvious.
In conjunction with Fig. 1, Fig. 2, Fig. 3, Fig. 4, this shock absorption device also comprises that at least two energy adjust air bellow 5 and the adjusting mechanism of self rigidity automatically according to actual condition.Air bellow 5 symmetries, be vertically mounted between cab framework 1 and cab legs 10, the top of air bellow 5 is bolted on the bottom surface of cab framework 1, and the bottom of air bellow 5 is bolted on the support 10 of operator's compartment.
Adjusting mechanism comprises vertically disposed pull lever 6 and horizontally disposed levelling valve 7, pull lever 6 tops are bolted on cab framework 1, the valve body of levelling valve 7 is bolted in cab legs 10, and be communicated with the air bag of air bellow 5 by air receiver, the pull bar of the tail end of pull lever 6 and levelling valve 7 is bolted.When operator's compartment is excited upwards to vibrate, drive pull bar 6 actions, thereby make levelling valve 7 connect exhaust gas circuit, the gas in air bag is extruded in air receiver, makes air bag inner chamber form negative pressure, thereby gives a downward power of operator's compartment, on prevention operator's compartment continues, moves; When operator's compartment moves down, levelling valve 7 is connected air inlet gas circuit, and the pressure gas in air receiver enters air bag, increases the air pressure of air bag inner chamber, to operator's compartment, provides a bearing capacity making progress, and stops operator's compartment to continue to move down.In addition, according to varying in size of levelling valve 7 switch valve ports, the compressed gas volume that increases in air bag or reduce is different, thereby for air bellow 5 provides different rigidity, reduces the amplitude that operator's compartment raises or reduces, and improves passenger's comfort level.
Air bellow 5 is used in conjunction with bumper, can automatically adjust according to actual condition the rigidity of self, again can fast speed damped vibration energy, and the traveling comfort and the safety that have improved operator's compartment passenger riding.
In addition, in order to realize better shock-absorbing function, in the utility model, between air bellow 5, be also horizontally installed with Panhard rod, Panhard rod comprises stabilizer rod body 8, left support abutment 11 and right support abutment 12, left support abutment 11 and right support abutment 12 are welded on respectively in cab framework 1 and cab legs 10, and stabilizer rod body 8 two ends are connected with right support abutment 12 with left support abutment 11 respectively by bolt.According to the performance characteristics of air bellow 5 self, can only bear the up-down vibration of operator's compartment.But non-highway wide dumper offset cab, self exists side to turn phenomenon, must install Panhard rod additional.Because Panhard rod two ends are separately fixed in cab framework 1 and cab legs 10, not only can limit the horizontal hunting of cab framework 1, and can avoid the too early damage of air bellow 5.
Simultaneously, between air bellow 5, be also vertically installed with longitudinal spacing mechanism 9, longitudinal spacing mechanism 9 is positioned at the middle part of cab framework 1 and cab legs 10, longitudinal spacing mechanism 9 bottoms are bolted in cab legs 10, the top of longitudinal spacing mechanism 9 is at right angles crooked, and sweep is bolted on the bottom surface of cab framework 1.Because longitudinal spacing mechanism is separately fixed in cab framework 1 and cab legs 10 at two ends Shang Xia 9, while guaranteeing that operator's compartment Oscillation Amplitude transfinites value, operator's compartment is all the time on the perch in permission.
