Summary of the invention
The object of this invention is to provide a kind of operator's compartment floating suspending apparatus entirely, there is vibration isolating effect difference, drives the not good problem of comfort level in the half suspended device that this device can solve existing medium-sized commercial vehicle/comm..vehicle.
In order to solve the problem, the technical solution used in the present invention is: this operator's compartment entirely floating suspending apparatus comprises and is connected to two groups of front overhang assemblies between both sides vehicle frame and operator's compartment longeron and rear overhang assembly, described rear overhang assembly has rear overhang shock absorber, and described two groups of front overhang assemblies are connected by a stabilizer rod, often organize described front overhang assembly and comprise the front overhang upper bracket be connected with described operator's compartment longeron and the front overhang undersetting being fixed on described frame outside wall, the upper end of described front overhang undersetting is fixed with the turning supporting seat be connected with described stabilizer bar end, described stabilizer rod is provided with spacing shoulder, described stabilizer rod is hinged with swing arm between described spacing shoulder and described turning supporting seat, the other end and the described front overhang upper bracket of described swing arm are hinged, the madial wall of described swing arm connects the front overhang shock absorber erect and arrange, the other end of described front overhang shock absorber is connected with described front overhang upper bracket, the supplemental support support that described front overhang upper bracket has base plate, side plate and is connected with described front overhang shock absorber, the lateral wall of described side plate and described operator's compartment longeron offsets, the front end of described operator's compartment longeron has the spacing rib of bending, described spacing rib is placed between described side plate and described supplemental support support, and described supplemental support support is connected with described spacing rib, the top of the described front overhang undersetting of described two groups of front overhang assemblies is bending to the direction mutually deviated from.
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, 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 present invention compared with prior art has following beneficial effect:
1, front overhang of the present invention 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 invention will be further described:
