Description
Technical field
The utility model relates to Cab mounting assembly field, specifically a kind of N9 Cab mounting assembly.
Background technology
Along with the continuous upgrading of heavy goods vehicles technology, the safety of the travelling comfort how improving chaufeur, the strength at repeated alternation alleviating chaufeur, raising vehicle has become the key factor of designer's consideration.At present, European heavy motor vehicle has been widely used the new mode of the air suspension comprising air bellow and Quan Sidian vibration suspension.Conventional heavy-duty automobile cab suspension adopts semi-floating design, and not only cost is high, and the total root mean square of weighed acceleration of the vibration of oscillation frequency and steering position is also comparatively large, and traveling comfort is poor, and operator's compartment can be also that fulcrum makes pitch rotation with front suspension support.
Summary of the invention
The utility model, in order to solve the problems of the technologies described above, provides a kind of N9 Cab mounting assembly.
The utility model is achieved through the following technical solutions: N9 Cab mounting assembly, comprises cabin front suspension and put assembly and driving cab rear suspension assembly,
It is to be symmetrical set by two and the consistent left front portion mechanism of structure and right front portion mechanism are formed that cabin front suspension puts assembly; Described left front portion mechanism and right front portion mechanism include cab turning mechanism, to be fixed on below cab turning mechanism and bolt is fixed on the front overhang bearing in vehicle frame front, be articulated with the front air bellow bumper at the upper side of cab turning mechanism, be articulated with the front overhang support of opposite side above cab turning mechanism, be fixed on the front levelling valve on front overhang support, the front levelling valve yaw bar that one end of described front levelling valve is arranged is connected with cab turning mechanism by front levelling valve adjust bar; Two cab turning mechanisms of left front portion mechanism and right front portion mechanism are flexibly connected by connecting rod;
Driving cab rear suspension assembly to be symmetrical set by two and the consistent left back portion mechanism of structure and right back portion mechanism are formed, described left back portion mechanism and right back portion mechanism include the rear overhang bearing that bolt is fixedly connected on vehicle frame rear, hinged support is in the rear air bellow bumper of rear overhang holder top side, be connected to the hydraulic lock support of rear air bellow bumper upper end, be assemblied in the lock support that hydraulic lock support coordinates with hydraulic lock bracket hydraulic, be fixed on the connection bracket of rear overhang holder top opposite side in assembling of tilting, one end is articulated with the transverse damper on hydraulic lock support, be assemblied in the rear levelling valve in connection bracket, the rear levelling valve yaw bar that one end of described rear levelling valve is arranged is connected with hydraulic lock support by rear levelling valve adjust bar, be connected by crossbeam between left back portion mechanism and two connection bracket upper ends of right back portion mechanism, and the other end of two transverse dampers is all articulated with on crossbeam.
During concrete use, the upper end that the cabin front suspension of N9 Cab mounting assembly described in the utility model puts the described front air bellow bumper of assembly is fixedly connected on cab front wall, front overhang pedestal upper end is fixedly connected on cab floor, and the lock support of driving cab rear suspension assembly is fixedly connected on cabin rear wall.
When vehicle is subject to impacting, height between cab floor and vehicle frame can change, this change is directly reflected by front levelling valve adjust bar and rear levelling valve adjust bar, thus control the intake and exhaust of air bellow bumper: when highly becoming large, levelling valve adjust bar drives levelling valve yaw bar to move downward, levelling valve carries out deflating action, air bag volume-diminished, thus reduces the distance between cab floor and vehicle frame; When highly diminishing, levelling valve adjust bar drives levelling valve yaw bar upward movement, and levelling valve carries out inflation action, and air bag volume increases, thus increases the distance between cab floor and vehicle frame.Air bellow bumper is main vibration isolation element of the present utility model, can strengthen the vibratory impulse absorbing and be passed to operator's compartment from vehicle frame, improves the traveling comfort that chaufeur is taken.Left back portion mechanism and right back portion mechanism connect as one by the crossbeam of driving cab rear suspension assembly, improve the integral rigidity of driving cab rear suspension assembly, when operator's compartment rolls, the impact of operator's compartment to air bellow bumper can be reduced, improve the service life of air bellow bumper; And the hydraulic pressure between hydraulic lock support with lock support coordinates and ensures when being put in place by operator's compartment locking, avoid departing from driving conditions, face upward before causing operator's compartment and excessively cause overturning.
Compared with prior art, it has following beneficial effect to N9 Cab mounting assembly described in the utility model:
(1) can rigidity be reduced by increasing air bellow bumper bag volume and have nothing to do with load;
(2) height of the carbody can be made not by the impact of load, remain constant;
(3) rigidity is with load change, and the natural frequency of vibration remains unchanged substantially, ensure that the traveling comfort of operator's compartment;
(4) there is less rigidity, the absorption of high-frequency vibration and sound insulation value good.
