Abstract

The invention discloses a rear suspension device for a heavy-duty truck cab and relates to the technical field of automobile manufacturing. The rear suspension device comprises a rear suspension shock absorber, a rear suspension arched girder of which two ends are provided with rear suspension lower supports, and a rear suspension floating beam of which two ends are connected with a hydraulic lock mounting plate, wherein two ends of the rear suspension shock absorber are respectively and vertically hinged to the lower part of the hydraulic lock mounting plate and a rear suspension shock absorber mounting plate on the rear suspension lower supports; and a rear suspension tie rod is arranged between the hydraulic lock mounting plate and the rear suspension arched girder. According to the rear suspension device, the problem that the automobile cab has low comfort level, low stability and low operating safety in the prior art can be solved.

Description

The heavy truck cab rear linkage
Technical field
The present invention relates to field of automobile, especially a kind of suspension gear for the truck cab.
Background technology
Car 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.The automobile cab rear linkage is a kind of device with operator's compartment and vehicle frame floating connection, has preferably vibration-damping function, can decay to be delivered to vibration on the operator's compartment from vehicle frame.Traditional cab rear suspension is only at the vertical shock absorber that is equipped with, this class rear linkage can only play attenuation to the vibration of vertical direction, and vibration that can not the effective attenuation side direction, thereby reduced the traveling comfort of operator's compartment, cab structure is easily produced under effect of vibration damage.Therefore adopt this 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.
Summary of the invention
Technical matters to be solved by this invention provides a kind of heavy truck cab rear linkage, 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 rear linkage includes 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 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.。
Further: 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, two undersettings of the present invention link to each other with vehicle frame by bolt, are used for transmitted load, utilize header board and rear overhang undersetting to be fixedly connected into " C " word shape, by the rigidity of vehicle frame, have improved significantly resistance to bending.
2, rear overhang bumper two ends vertically are hinged on respectively on the rear overhang shock absorber mounting board on hydraulic lock adapter plate bottom and the rear overhang undersetting, the vibration of the vertical direction that can decay.
3, hard-wired rear overhang intermediate rod between hydraulic lock adapter plate and rear overhang arched girder, the horizontal vibration that enough decays can make vehicle adapt to different road conditions; Rear linkage can either relax the impact of vertical direction like this, 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, guarantee stability and the handling safety of operator's compartment.
Description of drawings
Fig. 1 is the structural representation of the embodiment of the invention.
The specific embodiment
Below in conjunction with accompanying drawing embodiment is described in further detail:
Heavy truck cab rear linkage shown in Figure 1 includes rear overhang bumper 5, rear overhang arched girder 13, rear overhang floating beam 2; At rear overhang arched girder 13 two ends rear overhang undersetting 8 is installed, rear overhang arched girder 13 is fixedly connected into " C " word shape with rear overhang undersetting 8; Rear overhang floating beam 2 two ends are connected with hydraulic lock adapter plate 4; Rear overhang shock absorber mounting board 10 is installed on the rear overhang undersetting 8, and rear overhang bumper 5 two ends vertically are hinged on respectively on hydraulic lock adapter plate 4 bottoms and the rear overhang shock absorber mounting board 10; Rear overhang bumper 5 is the air bellow bumper; At rear overhang undersetting 8 height adjusting valve 7 is installed; Height adjusting valve 7 is connected with hydraulic lock adapter plate 4 by adjust bar 6; Height adjusting valve 7 can be regulated air bag rigidity, in order to better realize vibration damping.
Left side hydraulic lock adapter plate 4(can be right side hydraulic lock adapter plate or both sides hydraulic lock adapter plate at other embodiment) and rear overhang arched girder 13 between be hinged with rear overhang intermediate rod 12; Hydraulic lock adapter plate 4 tops are equipped with hydraulic lock 11, and hydraulic lock adapter plate 4 upper articulations have the switch block 3 that is connected with rear overhang upper bracket 1, and hydraulic lock 11 is captiveed joint with automobile cab by rear overhang upper bracket 1; Switch block 3 plays the effect of locking operator's compartment; Bumper 5 at right angle settings can slow down the impulsive force of above-below direction when vehicle is capable to be driven, and when vehicle generation double swerve, the power that the rear overhang intermediate rod is about 12 pairs is alleviated; Rear linkage can either relax the impact of vertical direction like this, 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, guarantee stability and the handling safety of operator's compartment.
