Description
Technical field
The present invention relates to field of automobile, especially a kind of suspension gear for the truck cab.
Background technology
Automobile in motion, the vibration on the operator's compartment mainly is delivered on the operator's compartment by chassis suspension, engine mounting, operator's compartment suspension by the road surface.Traditional automobile cab vehicle body all adopts the direct coupled mode of common vibration damping to link to each other with vehicle frame.The operator's compartment of domestic main autotruck product is most at present adopts with the suspension system of elastomeric material as suspension members, this structure is travelled under the flat road surface condition with the low speed of a motor vehicle for vehicle, and the vibration that is delivered on the operator's compartment is had certain obstruct and mitigation.But when vehicle in the situation that the speed of a motor vehicle is higher travels, or when a bit weaker road of pavement conditions travels, rubber mounting is well damped vibration just, the structural vibration that produces in the operator's compartment and the structureborne noise that is caused by high-frequency vibration are larger, thereby reduced the traveling comfort of operator's compartment, cab structure has easily been produced under effect of vibration damage.Therefore adopt this common vibration damping mode, effectiveness in vibration suppression is not obvious between automobile cab vehicle body and the vehicle frame, exists the impact by the road surface to pass to automobile chassis frame and cause that the vibration of operator's compartment is larger, and operator's compartment does not have good ride comfort; On the other hand, this common vibration damping mode does not have anti-trim ability yet, and fore-and-aft stability and the handling safety of operator's compartment are relatively poor.
Summary of the invention
Technical matters to be solved by this invention provides a kind of heavy truck cab suspension gear, and it can solve, and prior art automobile cab traveling comfort is poor, stability is inadequate and the relatively poor problem of handling safety.
In order to address the above problem, technical scheme of the present invention is: this heavy truck cab suspension gear comprises front-end equipment and rear linkage; Described front-end equipment comprises the front overhang stabilizer rod, be installed in consistent left suspension gear and the right suspension gear of structure at described front overhang stabilizer rod two ends, the two has included the front overhang upper bracket described left suspension gear and right suspension gear, front overhang undersetting, front overhang bumper and spring; Described front overhang undersetting one end is captiveed joint with vehicle frame, and the other end is connected with front overhang trip shaft bearing, at described front overhang trip shaft bearing the front overhang trip shaft is installed, and described front overhang trip shaft is hinged with the bull stick that is connected with described front overhang upper bracket; The two ends of described front overhang bumper are hinged with described front overhang upper bracket and described front overhang trip shaft respectively; Described spring one end is socketed on the front overhang limiting stopper that is connected with described front overhang trip shaft, and the other end is connected on the described front overhang upper bracket;
Described rear linkage, include the rear overhang bumper, two ends are equipped with the rear overhang arched girder of rear overhang undersetting and the rear overhang floating beam that two ends are connected with the hydraulic lock adapter plate, and described rear overhang bumper two ends vertically are hinged on respectively on the rear overhang shock absorber mounting board on described hydraulic lock adapter plate bottom and the described rear overhang undersetting; Between described hydraulic lock adapter plate and the described rear overhang arched girder rear overhang intermediate rod is installed.
In the technique scheme, more specifically scheme can be: described spring is coil spring; Described front overhang limiting stopper is columniform rubber block; Described rear overhang bumper is the air bellow bumper; At described rear overhang undersetting height adjusting valve is installed; Described height adjusting valve is connected with described hydraulic lock adapter plate by adjust bar; Described rear overhang arched girder and described rear overhang undersetting are fixedly connected into " C " word shape.
Owing to having adopted technique scheme, compared with the prior art the present invention has following beneficial effect:
1, adopts the front mechanical rear gasbag shock-damping structure of operator's compartment, by adjusting front overhang helical spring rigidity and the damping of front overhang bumper, and rear overhang air-bag vibration damper assembly is adjusted into vertical layout, swing for suppressing operator's compartment simultaneously, increase rear overhang rubber intermediate rod, can make vehicle adapt to different road conditions, can either relax the impact of vertical direction, vertical direction and horizontal vibration can decay simultaneously again, has preferably vibration-damping function, can alleviate from vehicle frame and be delivered to vibration on the operator's compartment, make operator's compartment have good ride comfort.
2, two undersettings of rear linkage of the present invention link to each other with vehicle frame by bolt, are used for transmitted load, and the bow-shaped structural that utilizes header board and rear overhang undersetting to be connected to form by the rigidity of vehicle frame, has improved resistance to bending significantly.
3, have good anti-trim ability, guarantee fore-and-aft stability and the handling safety of operator's compartment.
