Above-mentioned operator's compartment floats in the technical scheme of suspending apparatus entirely, technical scheme can also be more specifically: described front overhang undersetting has the connection bent plate be connected with described vehicle frame and the reinforced plate being arranged at described connection bent plate one side, described reinforced plate is perpendicular to described connection bent plate, and described connection bent plate and described reinforced plate are equipped with multiple through hole and fin.
Further, the damping coefficient of described front overhang shock absorber is 0.8 ~ 3.5 Newton-second/rice, and dumping force is 300 ~ 4000 Ns; The damping coefficient of described rear overhang shock absorber is 0.8 ~ 3.5 Newton-second/rice, and dumping force is 300 ~ 4000 Ns.
Further, the curve form of described front overhang undersetting, described swing arm and described front overhang upper bracket is obtained by topological optimization.
Owing to have employed technique scheme, the utility model compared with prior art has following beneficial effect:
1, front overhang of the present utility model have employed the assemblies such as the shock absorber that significantly can absorb impact and damped vibration, thus by the Cab mounting of medium-sized commercial vehicle/comm..vehicle by original half floating outstanding be improved to 4 entirely floating outstanding, its vibration isolating effect is good, improve medium-sized commercial vehicle/comm..vehicle ride performance, improve driving comfort level.
2, swing arm and stabilizer rod and front overhang upper bracket hinged, the setting of front overhang shock absorber is arranged between the supplemental support support of swing arm madial wall and front overhang upper bracket front end, this structure design can avoid the problem because of the comfort level difference caused that is coupled, improve decoupling zero rate, make ride comfort and reliability all quite stables of operator's compartment, and structure is simple, compact, is beneficial to and saves space arrangement space.
3, dumping force and damping coefficient by hanging shock absorber before and after adjustment carry out optimal damping curve, to improve ride comfort, reduce driver and crew's degree of fatigue.
4, Cab mounting support adopts topological optimization, under the prerequisite meeting requirements for quality, can reduce deadweight, be beneficial to reduce costs.
Accompanying drawing explanation
Fig. 1 is the structural representation of this Cab mounting device.
Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the utility model is described in further detail:
Operator's compartment shown in Fig. 1 entirely floating suspending apparatus mainly comprises two groups of front overhang assemblies 3, rear overhang assembly 5 and stabilizer rod 2, front overhang assembly 3 and total 5 one-tenth four ends be connected between both sides vehicle frame 1 and operator's compartment longeron 4 of rear overhang, forms at 4 and entirely floats outstanding.Two groups of front overhang assemblies 3 are connected by a stabilizer rod 2, and the stabilizer rod 2 in the present embodiment is a cylindrical straight-bar, and stabilizer rod 2 is symmetrically arranged with two spacing shoulders 21; Often organize front overhang assembly 3 and include front overhang undersetting 31, turning supporting seat 32, swing arm 33, front overhang shock absorber 34 and front overhang upper bracket 35, wherein, front overhang undersetting 31 is fixedly installed in the lateral wall of vehicle frame 1, the top of front overhang undersetting 31 is bent outwardly inclination, and namely the top of the front overhang undersetting 31 of two groups of front overhang assemblies 3 is bending to the direction mutually deviated from; The turning supporting seat 32 be connected with stabilizer rod 2 termination is fixed with in the upper end of front overhang undersetting 31, stabilizer rod 2 is hinged with swing arm 33 between spacing shoulder 21 and turning supporting seat 32, the other end and the front overhang upper bracket 35 of swing arm 33 are hinged, one end of swing arm 33 stable connection bar 2 have turn to relevant position after coordinate spacing projective structure with front overhang undersetting 31; Front overhang upper bracket 35 is connected with operator's compartment longeron 4, front overhang upper bracket 35 has base plate, side plate 352 and is placed in the supplemental support support 351 of operator's compartment longeron 4 front end, side plate 352 offsets with the lateral wall of operator's compartment longeron 4, the front end of operator's compartment longeron 4 has the spacing rib 41 of bending, spacing rib 41 is placed between side plate 352 and supplemental support support 351, and supplemental support support 351 and spacing rib 41 are connected to a fixed; The madial wall of swing arm 33 connects the front overhang shock absorber 34 erect and arrange, and the other end of front overhang shock absorber 34 is connected with the supplemental support support 351 of front overhang upper bracket 35; Preferably, the damping coefficient of front overhang shock absorber 34 is 0.8 ~ 3.5 Newton-second/rice, and dumping force is 300 ~ 4000 Ns.The structure of the rear overhang assembly 5 of the present embodiment has been open in 201210489894.6 at application number, does not repeat them here; Preferably, the damping coefficient of rear overhang shock absorber 51 is 0.8 ~ 3.5 Newton-second/rice, and dumping force is 300 ~ 4000 Ns.It is worth mentioning that, front overhang undersetting 31 has the connection bent plate 311 that is connected with vehicle frame 1 and is arranged at the reinforced plate 312 connecting bent plate 311 1 side, reinforced plate 312 is perpendicular to connection bent plate 311, and connection bent plate 311 and reinforced plate 312 are equipped with multiple through hole 314 and fin 313; In addition, the curved shape of front overhang undersetting 31, swing arm 33 and rear overhang undersetting is obtained by topological optimization, to reduce deadweight, reduces cost.
