Fig. 1 is the utility model structural representation;
Fig. 2 is the structure for amplifying scheme drawing of part 15 among Fig. 1;
Fig. 3 is rearmounted bolster air suspension air-path control system scheme drawing;
Among the figure: 1 operator's compartment, 2 driving engines and annex, 3 power-transfer clutchs, 4 change speed gear boxs, 5 transmission shafts, 6 double drive axles, steering shaft I before 7,8 front spring spring I, steering shaft II before 9,10 front spring spring II, 11 vehicle frames, 12 wheels, 13 rear leaf springs, 14 rearmounted twins bolsters, 15 rearmounted bolster air suspensions, 16 equalizer supports, 17 equalizers, 18 Connection Blocks, 19 carrying air bags, 20 shock absorbers, 21 propelling rods, 22 air receivers, 23 by pass valves, 24 air pressure sense voltage adjustment of on-load valves, 25 test splices, 26 safety valves, 27 buffering air receivers.
(5) body embodiment
A kind of specific embodiment as shown in the figure comprises operator's compartment 1, driving engine and annex 2, transmission system, steering system, running device, brake system and electric system.Transmission system is made up of power-transfer clutch 3, change speed gear box 4, change speed gear box manipulation, clutch control, transmission shaft 5, double drive axle 6 etc., mainly by preceding steering shaft I7, preceding steering shaft II9, rearmounted twins bolster 14, vehicle frame 11, wheel 12, front spring spring I8, front spring spring II10, rear leaf spring 13, rearmounted twins bolster 14 and rearmounted bolster air suspension 15, rearmounted bolster air suspension 15 has air-path control system to described running device.
Rearmounted twins bolster 14 is connected with vehicle frame 11 by rearmounted bolster air suspension 15, the propulsive effort of double drive axle 6 is delivered on the rearmounted twins bolster 14 through vehicle frame 11, rearmounted bolster air suspension 15, to realize being installed in the motion of the wheel on the rearmounted twins bolster 14.In addition, ground passes on the vehicle frame 11 by rearmounted twins bolster 14, rearmounted bolster air suspension 15 in the face of the braking force of wheel, needs with the braking that realizes car load.
Equalizer 17 1 sides of rearmounted bolster air suspension 15 and pass through equalizer support 16 and be connected with vehicle frame 11, be connected with rearmounted twins bolster 14 by Connection Block 18 on the other hand, the propelling rod 21 of rearmounted bolster air suspension 15 is connected with vehicle frame 11, rearmounted twins bolster 14.The carrying air bag 19 of rearmounted bolster air suspension 15 is connected with equalizer 17 and vehicle frame 11.As can be seen from Figure 2: there are following relation: F=FI*L/L1 in the axle load F of rearmounted twins bolster 14 and the bearing capacity FI of carrying air bag 19, therefore, available less carrying air bag satisfies the axle load requirement of rearmounted twins bolster, and this also is one of advantage of single arm type air suspension.
The two ends of the shock absorber 20 of rearmounted bolster air suspension 15 link to each other with vehicle frame 11, equalizer 17 respectively; can produce damping to the vertical bounce of rearmounted twins bolster 14 relative vehicle frame 11 in the vehicle operating process, thus protection carrying air bag 19 and raising car load operation ride comfort.
Rearmounted bolster air suspension air-path control system (as Fig. 3) has been used by pass valve 23, air pressure sense voltage adjustment of on-load valve 24 and safety valve 26, when the air pressure in the air receiver 22 is crossed when low, pressurized air impassabitity by pass valve 23, thus braking gas circuit air pressure guaranteed, guarantee the brake safe performance.Air pressure sense voltage adjustment of on-load valve 24 is used for regulating the air pressure that carries air bag 19 according to the load-carrying situation, to guarantee the traction of double drive axle 6, guarantees the car load dynamic property.Safety valve 26 guarantees that carrying air bag 19 pressure are no more than authorized pressure, to guarantee to carry the safety of air bag.The buffering air receiver 27 be installed in the carrying air bag 19 near, when vehicle frame 11 makes the gas pressurized that holds in my air bag 19 with rearmounted twins bolster 14 relative beating, when pressure raises, gas can expand in buffering air receiver 27, can effectively reduce the gas temporary impact pressure in the carrying air bag 19, avoid carrying air bag 19 being caused damage because of safety valve 26 response lags.Test splice 25 is housed on air-path control system, can carries the measurement of air bag air pressure easily, so that air pressure sense voltage adjustment of on-load valve 24 is carried out parameter adjustment.
