Description
Technical field
The utility model relates to the floating full rear suspension device of a kind of operator's compartment.
Background technology
The floating full rear suspension device of the operator's compartment that has occurred in the market, as the patent No. is that 02281153.2 Chinese patent discloses a kind of operator's compartment rear suspension device, and wherein a kind of comprises a rear overhang float crossbeam, the left back upright beam that suspends, right back upright beam, vibration damper complement, the elastic element and be connected lock assembly of suspending.Wherein, rear overhang upright beam in the left and right sides places the below of the unsteady crossbeam of rear overhang respectively, vibration damper complement vertically is connected in rear overhang and floats between crossbeam and the upright beam of left and right rear overhang, its upper end links to each other with the unsteady crossbeam of rear overhang, its lower end is connected with the upright beam of left and right rear overhang, and elastic element is placed on the vibration damper complement, connects lock assembly and comprises connection lock and locking bolt support, locking bolt props up and is placed on the float crown center of crossbeam of rear overhang, connects lock and is placed on the locking bolt support in the middle of the body tail by being assemblied in.This suspending can completely cut off certain vibration, and traveling comfort and ride comfort all have some improvement.
This deficiency that exists that suspends is reflected in the following aspects:
This suspends and adopts the spring of deciding rigidity to support, and the rigidity that suspends remains unchanged.But when the suffered load of operator's compartment was excessive, the vertical deformation that suspends also can be excessive, might surpass the deflection that allows, thereby destroy ride comfort.Therefore, this suspends to such an extent that rigidity is often done greatlyyer, but bigger rigidity is unfavorable for absorbing impact energy, causes cushion characteristic poor.By theory of oscillation as can be known, spring stiffness is big more, and transmission of vibration is also big more, so its vibration isolation is also bad.
Because this rigidity that suspends is for deciding rigidity, remain unchanged, when the suffered load of operator's compartment produced bigger variation, the vertical deformation that suspends also changed bigger, thereby the number of times variation in operator's compartment up-down vibration in the unit time is too fast, and also promptly the frequency change of vibration is too fast.Be unfavorable for making the vibration of operator's compartment to be stabilized in the adaptable frequency limit of human body institute like this, promptly effectiveness in vibration suppression is poor.
This suspends and adopts the hydraulic pressure locking bolt that is positioned at the floating beam centre that thereby the operator's compartment locking can not overturn, when the operator's compartment upward movement, locking bolt holds it for the downward pulling force of operator's compartment, thereby only realizes upwards spacing by a bit, occur operator's compartment easily and tilt to both sides, therefore stability is bad.
When operator's compartment moved downward, the V-arrangement rubber block of the floating beam left and right sides was to the weight of upper support operator's compartment, by the support of these 2 realizations to it.But because locking bolt with operator's compartment locking and connection, is positioned at middle locking bolt and also can gives the support of operator's compartment to make progress, therefore actual have operator's compartment is supported at 3.Because 3 strong points are arranged simultaneously on a floating beam, obligatory point is too much, certainly will cause the strong point fully not contact or have the gap, so portion can support operator's compartment by actv., promptly stable bad; Simultaneously also can bring obligatory point to occur the situation of stress concentration easily.
On structural strength, existing complete floating rear suspension device adopts two independently modes of supporting respectively of left and right sides lower bracket, because globality is bad, when vehicle frame distorts in generation, it is little that left and right sides lower bracket produces this deformation ability of opposing, unfavorable to the attitude that keeps operator's compartment; Simultaneously, when transmitting bigger impact load between operator's compartment and chassis, the insufficient strength of left and right sides lower bracket can produce stress concentration in the junction.
Summary of the invention
For addressing the above problem, the utility model provides a kind of operator's compartment floating full rear suspension device, can be to operator's compartment effectively buffering, vibration damping and spacing, and lateral stability is good.
The floating full rear suspension device of automobile cab, comprise that the operator's compartment that upper left support and upper right support are formed is connected bracket assembly, the hydraulic pressure locking bolt, two are enclosed within the jounce bumper assembly that constitutes on the cylinder type damper by coil spring, left and right connection support down and two ends and the left and right following connection bracket assembly that is connected the crossbeam composition of support captive joint down, connect the hydraulic oil pipe of left and right sides hydraulic pressure locking bolt, it is characterized in that: also be provided with the swing arm that connects the jounce bumper assembly; Left and right connection support lower end down is connected on the vehicle frame, and the left and right upper end of connection support down is provided with hinge hole; The two ends up and down of the cylinder type damper of each jounce bumper assembly are provided with hinge hole, and the lower end of two cylinder type dampers is hinged by hinge hole, attaching parts are connected support with left and right time middle lower end; The hydraulic pressure locking bolt is formed by left and right two, left and right hydraulic pressure locking bolt is separately fixed in two swing arms, the inboard of two swing arms respectively the upper end by attaching parts, left and right down connection support hinge hole with left and right under to be connected support hinged, it is hinged that the upper end hinge hole and the cylinder type damper of attaching parts, cylinder type damper passed through in the outside of two swing arms respectively; Upper left support, upper right support upper end are respectively equipped with joint face and are connected with cab anchorage, the lower end of upper left support, upper right support is respectively equipped with the circular arc bearing surface, and the circular arc bearing surface of upper left support, upper right support is supported on respectively in the support slot of two hydraulic pressure locking bolts.
Below, on function, the utility model is described further:
Upper left support is connected with cab anchorage by bolt with upper right support, transmit from or put on the load of operator's compartment.
The lower bracket assembly is captiveed joint with vehicle frame by bolt, transmit from or put on the load of vehicle frame.Crossbeam is captiveed joint with left and right sides lower bracket assembly, can increase the counter-bending deformation ability of left and right sides lower bracket, the stress concentration of having avoided lower bracket may occur in the junction of interior adapter shaft by actv..
The lockable mechanism of hydraulic pressure locking bolt foot operator's compartment.When oil pipe not during fuel feeding, the latch hook of hydraulic pressure locking bolt can self-return, thereby with the circular arc bearing surface of the upper left support of locking, upper right support, thereby limited the operator's compartment upset forward that may occur.When oil pipe to the left and right during hydraulic pressure locking bolt assembly fuel feeding, the latch hook of left and right sides hydraulic pressure locking bolt is opened respectively, has removed the locking to operator's compartment.
Hydraulic pressure locking bolt, swing arm and jounce bumper assembly upper bracket with under be connected between the support, transmit the various load between operator's compartment and the vehicle frame together, wherein, the function of the existing locking of hydraulic pressure locking bolt has the function of transmitting above-below direction load again.
Contrast existing complete floating rear suspension device, the effect that suspends after the utility model is floating entirely is embodied in the following aspects:
One, on the arrangement of spring and shock absorber, be different from the mode of the vertical support of existing complete floating rear suspension device, adopted the structural shape of shock absorber with the oblique layout support of the spring of deciding rigidity, can realize better buffering and vibration damping, and total deformation is less, satisfies the requirement of spatial destribution.
When 1, operator's compartment moves downward
Because the upper end of spring is supported in the outside of swing arm, when the operator's compartment band lock pin and is moved downward, by geometric relationship, the arc length that the outer end of swing arm slips over is more much bigger than displacement, and the actionless relatively spring lower end, spring upper end that is connected in outside the swing arm also can produce bigger compress variation, the restoring force increase that spring makes progress is very fast, increase along with load, the restoring force of spring is nonlinear and increases progressively, promptly realized becoming the nonlinear characteristic of the spring of rigidity, can resist the trend that operator's compartment moves downward rapidly, made operator's compartment reach balance, avoid downward excessive rapid displacement and acceleration/accel, realized flexible buffering.
2, during the operator's compartment upward movement
Because spring is in compressive state installing under the state of equilibrium, when operator's compartment was crossed installation equilibrium point upward movement, spring just recovered compressive deformation gradually, and restoring force upwards; When operator's compartment moved up to spring and is in free state, spring i.e. power by compression not; When operator's compartment continues upwards, spring promptly is in extended state, and the restoring force of its generation is downward, resists the movement tendency that operator's compartment makes progress with gravity.
Identical when moving downward, the little displacement meeting of operator's compartment causes the displacement that spring is bigger, thereby obtains the nonlinear restoring force of spring.When operator's compartment is crossed the installation equilibrium point, and spring is the trend that the non-linear restoring force that makes progress that reduces can be eliminated the operator's compartment upward movement rapidly when not reaching free state, makes operator's compartment faster near equilibrium point is installed; When spring was in extended state when moving in the operator's compartment continuation, the downward restoring force that is non-linear increase can be eliminated the trend that operator's compartment continues upward movement rapidly, makes it to return to the balance position of installation.Under these states, excessive rapid displacement and the acceleration/accel of all having avoided operator's compartment to make progress, thus realized the buffering of the flexibility that makes progress.
Because this device possesses and can eliminate moving displacement up or down rapidly, so it can make total displacement less, can not surpass the scope that allows.Simultaneously,, increase initial displacement, improve the effect of buffering because these characteristics also can reduce the rigidity value of its spring.The rigidity of spring reduces, and the effect of transmitting vibrations also improves thereupon.
Because it possesses change rigidity, total change in displacement is little, so the oscillation frequency variation is also less, helps making oscillation frequency also to remain in the acceptable scope.
Generally speaking, up and down in the motion process, this device can both be realized the buffering of the flexibility of operator's compartment and vibration damping at operator's compartment.
Therefore, this supporting way can solve the deficiency of the existing complete floating rear suspension device of speaking of in the background technology, promptly its more existing complete floating rear suspension device of deflection is little up and down, ride comfort is good; Cushion softly, oscillation frequency also remains in the acceptable scope, and traveling comfort is good.
Two, on the locking mode, distinguish existing complete floating rear suspension device an and mode center lock locking, the structural shape that has adopted the right and left to end by the hydraulic lock bolt-lock respectively, lateral stability is good.
In the process of operator's compartment upward movement, the unsettled situation of the spacing operator's compartment that causes of single point can not appear, and promptly lateral stability is good.
Three, on supporting way, be different from the existing complete unsteady crossbeam that suspends after floating and the integrated support mode of V-arrangement rubber block, the independent mode that has adopted both sides to support has respectively overcome and has crossed the stress concentration that restricted problem is brought.
At the mistake orientation problem of existing complete floating rear suspension device, cancelled floating beam, left and right sides independent support, the mistake restricted problem in the time of can not occurring supporting, thus can not produce the stress concentration that constraint brings yet.
Four, on structural strength, be different from two of the existing complete floating rear suspension device independently modes that support respectively of left and right sides lower bracket, adopted crossbeam to connect the mode of left and right sides lower bracket, actv. has increased the intensity of left and right sides lower bracket, has avoided the stress concentration of junction.
Summary, this apparatus structure is simple, compact, cleverly by arranging, realized the non-linear-elastic characteristic of variable rate spring with the spring of deciding rigidity, than common rear suspension device better travelling comfort and riding comfort are arranged, resiliency and good stability do not have stress concentration, and this device has very high using value.
