Shock absorber is double adjustable shock absorber, and shock absorber and freely fitted damper spring coaxial line assemble.
Principle of work of the present utility model is: in compression stroke (vehicle body and vehicle frame close to each other), absorber damping force is less, to give full play to the elastic reaction of elastic element (damper spring), relax and impact, at this moment, elastic element plays a major role; In extension stroke (vehicle body and vehicle frame mutually away from), absorber damping force is comparatively large, to give full play to the damped vibration effect of shock absorber, thus reduce amplitude and the vibration number of body vibrations, at this moment, shock absorber plays a major role; When relative velocity when between vehicle body (or wheel) and vehicle frame is excessive, require that shock absorber can strengthen flow quantity automatically, make dumping force remain within certain limit, to avoid bearing excessive impact load.Vibration damper complement is used for the amplitude of rapidly decay body vibrations, vibration number to reach the object of quick vibration damping, and the guide position limiter increased vertical and cross travel necessarily can control operator's compartment, and when preventing motion, amplitude is excessive, affects traveling comfort; Through the checking of real vehicle multiple road, this vibration insulating system effectiveness in vibration suppression is obvious, improves the travelling comfort of driver and crew.
The utility model tool has the following advantages:
1. rear-suspending machinery vibration insulating system good damping result, structure is simple, easy to use, reasonable price;
2. the damping of vibration damper complement and the rigidity of spring are according to the feature matched design again of torsion bar upset operator's compartment, make effectiveness in vibration suppression more obvious, more optimized structure;
3. the gap of guide position limiter necessarily can control at vertical and cross motion operator's compartment with structure.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the partial enlarged drawing of guide position limiter.
Detailed description of the invention
In Fig. 1, the rear-suspending left socle assembly be symmetrically arranged is connected with vehicle frame by bolt with rear-suspending right support assembly, for operator's compartment provides support.Rear-suspending left socle assembly and rear-suspending right support assembly and vehicle frame 15 are rigidly connected by bolt.Its structure is illustrated: upper cushion assembly 2 is symmetrically arranged for rear-suspending left socle assembly, be bolted on U-shaped bracket 3 two ends, support the bracket of rear cabin 16 both sides, decay with the part of vehicle body vertical direction, cross travel in motion for the transition buffer directly supporting operator's compartment during locking.U-shaped bracket 3 bottom is rigidly connected by bolt and tray rack 8, upper cushion assembly 2 is bolted on U-shaped bracket 3, U-shaped bracket 3 is locked to operator's compartment by the latch hook on lockable mechanism when operator's compartment falls, and is provided with the locking riser 1 locked mutually with the latch hook of lockable mechanism in the middle part of U-shaped bracket 3.Hook with safety tong 4 on tray rack 8 and the secondary lock hook phase locking on lockable mechanism, carry out secondary locking, safer, reliable, hook with safety tong 4 is only arranged on the tray rack 8 of rear-suspending left socle assembly.Vibration damper complement, guide position limiter is connected with between tray rack 8 and left socle assembly 13.Vibration damper complement comprises damper spring 6, shock absorber 7, and shock absorber 7 lower end is undertaken hinged by bolt shaft 17 and left socle assembly 13, and bolt shaft is through the hole of shock absorber bottom, and shock absorber can do around bolt shaft 17 and rotate.Damper spring 6, shock absorber 7, guide position limiter, the assembly of their compositions plays vibration damping and restriction jointly when operator's compartment bob; The vibration damper complement that wherein the floating damper spring 6 installed and shock absorber 7 are formed plays main damping of vibrations, and guide position limiter provides guiding for operator's compartment bob and plays control action to bob amplitude.Wherein, 14 is right support assembly.
In Fig. 2, guide position limiter comprises guidepost 9, lubricating cup 10 and orienting sleeve 11.Guidepost 9 upper end is connected with tray rack 8 through bolt, and through orienting sleeve 11, left socle assembly 13 in the middle part of guidepost, vibration damping rubber cushion 12, large pad, two jam nuts are equipped with in guidepost lower end.Orienting sleeve 11 is provided with lubricating cup 10, and orienting sleeve 11 inwall has the annular oil groove corresponding with lubricating cup.When vibration damping rubber cushion 12 prevents end motion under guidepost and bracket assembly rigid contact, certain buffer action can be played simultaneously.Prevent from loosening with two jam nuts.
The lower cushion assembly used before the vibration damper complement adopting damper spring 6 and shock absorber 7 to form in this system substitutes, shock absorber adopts double adjustable shock absorber, thus makes new damper mechanism more simple, and whole apparatus system work is more steady.Feature due to operator's compartment torsion bar turnover mechanism: when operator's compartment is lockup state, this structure makes the twist angle of torsion bar be maximum, the now torque maximum of torsion bar, and the gravitational moment of operator's compartment is also maximum; After locking is removed, the torque of torsion bar is in operator's compartment front support, overcome operator's compartment gravitational moment, and apply less operator's compartment can be made to realize upset to lifting force, when driver's cab turnover is to maximum angular position, the energy of torsion bar discharges substantially, and the reversal rate of operator's compartment is decayed gradually, push away operator's compartment gently, rely on operator's compartment strut bar operator's compartment to be locked in the position of maximum flip angle; When putting down operator's compartment, operator's compartment utilizes self gravity fall, its gravitational moment increases gradually, operator's compartment front support makes its twist angle increase to torsion bar effect, then torsional drag force moment also increases, and overcomes gravitational moment, and the fall velocity of operator's compartment is reduced gradually, slightly apply external force, pull operator's compartment that it can be made to pin downwards.These features just require that the rigidity of the damper spring played a major role in the process that operator's compartment is beated downwards can not be too large, and the damping of vibration damper complement is less; The damping of the vibration damper complement played a major role in the process of upwards beating is comparatively large, and the amplitude of body vibrations of decaying rapidly and vibration number, to reach satisfied effectiveness in vibration suppression.Lock portion simultaneously in this system can well and safety locking mechanism assembly interlock, and there is secondary lock locking mechanism, considerably increase the safety of system, reduce the safety misadventure caused because of maloperation, make the safe more secure of navigating mate.Lockable mechanism structure is simple, safe and reliable.
