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.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 N8 Cab mounting assembly.
The utility model is achieved through the following technical solutions: N8 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 the front overhang bearing that bolt is fixed on vehicle frame front, the cab turning mechanism of hinged support on front overhang bearing, be articulated with the front shock absorber of front end, cab turning mechanism top, described front shock absorber top is connected on cab front wall, cab turning mechanism upper rear end is articulated with on cab floor, in the middle part of cab turning mechanism, top is fixedly connected on cab floor by upper bump rubber and the bracket be connected on upper bump rubber, is fixedly connected on vehicle frame below middle part by lower bump rubber; Be connected by connecting rod between left front portion mechanism and two cab turning mechanisms of right front portion mechanism;
Driving cab rear suspension assembly is 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 connected to vehicle frame rear, the vehicle body after poppet of vertical bolt support on rear overhang bearing, inclined shore is fixed on the vehicle body rear shock absorber on rear overhang bearing, bolt is fixed on the vehicle body latching mechanism on vehicle body rear shock absorber, the intermediate rod being articulated structure by two ends between vehicle body latching mechanism with vehicle body after poppet is connected, vehicle body latching mechanism is connected with lock by hydraulic lock, lock bolt is connected on cab floor, vehicle body after poppet top is supported in below lock by rear overhang bump rubber.
N8 Cab mounting assembly described in the utility model compared with prior art, has following beneficial effect:
(1) travelling comfort is improved: the vertical bounce displacement of semi-floating Cab mounting is 5 ~ 20 mm, and maximum vertical shake frequency can reach 15 Hz, bigger than normal, effectively cannot avoid the resonance frequency of vehicle frame; N8 Cab mounting assembly described in the utility model, operator's compartment vertical shake frequency, coil spring is 1.8 ~ 3 Hz, can avoid the resonance frequency of vehicle frame completely, the displacement of vertical bounce simultaneously also can reach 40-60mm, and the traveling comfort taken can increase substantially;
(2) space utilization degree is high: cab turning mechanism eliminates usually turning supporting seat used, adopts upper and lower sectional type foundry goods, increasing release workshop front space, be conducive to the layout of the products such as driving engine, extend product available model;
(3) reduce fault rate: rear overhang bump rubber directly contacts with lock, simultaneously horizontal damping adopts Rubber Parts, travels under the environment that operating mode is poor, can the vibration isolation element of available protecting suspension system, the fault rate of the parts such as reduction shock absorber.

Detailed description of the invention
N8 Cab mounting assembly, comprises cabin front suspension and puts 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 the front overhang bearing 2 that bolt is fixed on vehicle frame 1 front, the cab turning mechanism 3 of hinged support on front overhang bearing 2, be articulated with the front shock absorber 4 of front end, cab turning mechanism 3 top, described front shock absorber 4 top is connected on cab front wall 5, cab turning mechanism 3 upper rear end is articulated with on cab floor 6, in the middle part of cab turning mechanism 3, top is fixedly connected on cab floor 6 by upper bump rubber 7 and the bracket 8 be connected on upper bump rubber 7, below, middle part is fixedly connected on vehicle frame 1 by lower bump rubber 9, be connected by connecting rod 10 between left front portion mechanism and two cab turning mechanisms 3 of right front portion mechanism,
Driving cab rear suspension assembly is 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 11 that bolt is connected to vehicle frame 1 rear, the vehicle body after poppet 12 of vertical bolt support on rear overhang bearing 11, inclined shore is fixed on the vehicle body rear shock absorber 13 on rear overhang bearing 11, bolt is fixed on the vehicle body latching mechanism 14 on vehicle body rear shock absorber 13, the intermediate rod 15 being articulated structure by two ends between vehicle body latching mechanism 14 with vehicle body after poppet 12 is connected, vehicle body latching mechanism 14 is connected with lock 17 by hydraulic lock 16, lock 17 bolt is connected on cab floor 6, vehicle body after poppet 12 top is supported in below lock 17 by rear overhang bump rubber 18.
During concrete enforcement, the solid frequency of vehicle frame 1 is avoided by the rigidity value and damping value adjusting front shock absorber 4, reduce the probability that resonance occurs, the optimal value that the rigidity of cab turning mechanism 3 built-in rubber bump rubber is obtained by computer modeling simultaneously has also played very large effect to the raising of vibration isolation rate.
Further, the mode that vehicle body latching mechanism 14 and lock 17 are fastened by the hydraulic pressure of hydraulic lock 16 realizes operator's compartment locking.In the design process, by calculating operator's compartment weight distribution, drawing the rigidity of bumper, confirming damping size by experiment, more finally realizing vibration isolation and anti-rolling object by intermediate rod 15.
