Abstract
The invention discloses a front suspension device for a heavy-duty truck cab, relating to the technical field of truck manufacturing. The front suspension device comprises a front suspending stabilizer bar, a left suspension device and a right suspension device, wherein the left suspension device and the right suspension device respectively comprise a front suspending upper bracket, a front suspending lower bracket, a vibration damper and a spring; one ends of the front suspending lower brackets are fixedly connected with a frame and the other ends thereof are connected with front suspending turnover shaft brackets; front suspending turnover shafts are installed on the front suspending turnover shaft brackets; the front suspending turnover shafts are hinged with rotary bars connected with the front suspending upper brackets; the two ends of the vibration dampers are respectively hinged with the front suspending upper brackets and the front suspending turnover shafts; and one ends of the springs are sleeved on front suspending stop blocks connected with the front suspending turnover shafts and the other ends thereof are clamped on the front suspending upper brackets. Compared with the prior art, the front suspension device can solve the problems of poor comfort, insufficient stability and poorer operation safety of the truck cab.
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 common 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 travels in the higher situation of the speed of a motor vehicle, or when a bit weaker road of pavement conditions travels, the common well damped vibration that just suspends, 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 been produced under effect of vibration easily 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 front-end equipment, 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 front-end equipment comprises the front overhang stabilizer rod, left suspension gear and right suspension gear; Described left suspension gear is consistent with right suspension gear structure and be installed in the two ends of described front overhang stabilizer rod, and the two has included the front overhang upper bracket described left suspension gear and described right suspension gear, front overhang undersetting, 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 bumper are hinged with described front overhang upper bracket and described front overhang trip shaft respectively; One end of described spring is socketed in outside the front overhang limiting stopper that is connected with described front overhang trip shaft, and the other end is installed on the described front overhang upper bracket.
In the technique scheme, more specifically scheme can be: described spring is coil spring; Described front overhang limiting stopper is columniform rubber block.
Owing to adopted technique scheme, compared with the prior art the present invention has following beneficial effect:
1, has preferably vibration-damping function, can alleviate from vehicle frame and be delivered to vibration on the operator's compartment.
2, can decay rapidly impact by the road surface passes to automobile chassis frame and causes the vibration of operator's compartment, makes operator's compartment have good ride comfort.
3, have good anti-trim ability, guarantee fore-and-aft stability and the handling safety of operator's compartment.
