Description
Technical field
The utility model relates to automobile hanging technical field, is specially a kind of cabin front suspension and puts system.
Background technology
In the prior art, in order to improve the travelling comfort of truck cap, the high-end truck on home market generally adopts full-float cab front-suspension system.
A kind of operator's compartment full-floating front suspension device is disclosed in the Chinese utility model patent specification sheets that is CN200620095941.9 at application number, this device is linked together chassis and operator's compartment jointly by turnover bracket, flip-arm and front overhang upper bracket, and has arranged that vibration damper complement is for decaying from the vibration on chassis; Because the trip shaft of this device is fixed on vehicle frame front end with turnover bracket, trip shaft connects turnover bracket and flip-arm, so flip-arm drives front overhang upper bracket and vehicle frame generation relative motion when trip shaft axis rotates; When Vehicle Driving Cycle, although decayed by shock absorber from the vibration of vehicle frame vertical direction, from the vibration of vehicle frame fore-and-aft direction and left and right directions, there is no damping element decay.And, full-float cab front-suspension system due to complex structure and part kind on the high side, conventionally need to first be distributed into front-suspension assembly, when car load assembles, distinguish again the attachment point of connecting assembly on vehicle frame and operator's compartment, so cause assembling up also more difficult.
Summary of the invention
As can be seen here, do not provide can be by the scheme of the vibration damping of vehicle frame fore-and-aft direction and left and right directions for prior art.
Therefore, the deficiency existing in order to overcome prior art, the utility model is put system for the technical matters that will solve provides a kind of cabin front suspension, realizes the vibration damping of vehicle frame vertical direction, fore-and-aft direction and left and right directions.
For solving the problems of the technologies described above, the utility model cabin front suspension system of putting comprises that two ends are provided with stabilizer rod and a pair of air-bag shock absorber, upper bracket, absorber seat and the turnover bracket of flip-arm; Rear end and the turnover bracket of described flip-arm are hinged, the front end of described flip-arm is provided with mounting hole, in described mounting hole, be provided with trip shaft, the rear end of described flip-arm is hinged by the first bolt and turnover bracket, between described trip shaft and flip-arm, be provided with rubber coating, described trip shaft two ends are connected with upper bracket by the second bolt, and the upper/lower terminal of described air-bag shock absorber is hinged with upper bracket and absorber seat respectively.
As the above-mentioned cabin front suspension of the utility model, put the preferred version of system, described air-bag shock absorber, upper bracket and absorber seat three are vertical direction and arrange.
As the above-mentioned cabin front suspension of the utility model, put the further improvement of system, described turnover bracket is provided with air bag punching venting control cock, and described air bag punching venting control cock is connected with air-bag shock absorber by tracheae.
As the above-mentioned cabin front suspension of the utility model, put the further improvement of system, described air-bag shock absorber inner side is provided with limiting stopper.
The beneficial effects of the utility model are as follows: due to the upper/lower terminal of air-bag shock absorber respectively with upper bracket with absorber seat is hinged and air-bag shock absorber, upper bracket and absorber seat three are vertical direction and arrange, guaranteed in cab motions process that air-bag shock absorber is substantially in vertical best effort attitude, so can directly reflect front overhang vertical direction position relationship, realize flexibly connecting of operator's compartment and chassis, made effectiveness in vibration suppression better.Stabilizer rod is located to the front end of flip-arm, makes stabilizer rod preposition, thereby improved the torsional stiffness of front overhang system, bring into play better the anti-roll capability of operator's compartment.By rubber coating being set between trip shaft and flip-arm, trip shaft and operator's compartment are synchronized with the movement, vibration decays via rubber coating, the axial direction of trip shaft in rubber coating is bidirectionally limited, during driving, rubber coating energy actv. absorbs the vibration of the left and right directions bringing on road surface, improve traveling comfort, realized the vibration damping of vehicle frame vertical direction, fore-and-aft direction and left and right directions.In addition, trip shaft and upper bracket are easy to connect, have saved time of setting up when operator's compartment docks with chassis.
Read by reference to the accompanying drawings after the detailed description of the utility model embodiment, other features of the present utility model and advantage will become clearer.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in further detail, wherein:
Fig. 1 is the utility model structural representation.
Fig. 2 is the local structure for amplifying schematic diagram of the utility model.
Fig. 3 is rubber coating and trip shaft mounting structure schematic diagram in Fig. 1.
Fig. 4 is rubber coating and trip shaft mounting structure cutaway view.
The specific embodiment
Below in conjunction with accompanying drawing and the specific embodiment of the present utility model, the utility model cabin front suspension system of putting is made the following instructions.
Embodiment: the utility model comprises that two ends are provided with the stabilizer rod 5 of flip-arm 3, the front end of flip-arm 3 is provided with mounting hole, trip shaft 2 is positioned at the mounting hole of flip-arm 3 front ends, the rear end of flip-arm 3 is hinged with turnover bracket 7 by the first bolt 10, between trip shaft 2 and flip-arm 3, be provided with rubber coating 4, trip shaft 2 two ends are hinged with upper bracket 1 by the second bolt 12, the axial direction of trip shaft 2 in rubber coating 4 is bidirectionally limited, during driving, rubber coating 4 energy actvies absorb the vibration of the left and right directions bringing on road surface, improve traveling comfort.Air-bag shock absorber 6 is hinged with upper bracket 1 and absorber seat 8 respectively by the hanger of upper/lower terminal, air-bag shock absorber 6, upper bracket 1 and absorber seat 8 threes can be to vertical direction arranges, guaranteed in cab motions process that shock absorber is substantially in vertical best effort attitude, can directly reflect front overhang vertical direction position relationship, good damping result.Air-bag shock absorber 6 inner sides are provided with limiting stopper 11.
During installation, upper bracket 1 is connected with cab rigid, and absorber seat 8 is rigidly connected with vehicle frame, and air-bag shock absorber 6 is vertical connects upper bracket 1 and absorber seat 8, thereby has realized flexibly connecting of operator's compartment and chassis.Air bag punching venting control cock 9 is arranged on turnover bracket 7, regulates the inflation/deflation of air-bag shock absorber 6 when operator's compartment up-and-down movement, makes air-bag shock absorber 6 all the time in balance position, thereby reaches the effect that makes operator's compartment attitude stabilization.Turnover bracket 7 is rigidly connected with vehicle frame, and the rear end of flip-arm 3 is hinged on turnover bracket by the first bolt 10, and the rear end of flip-arm 3 can be around the first bolt 10 rotations.The motion that upper bracket 1 upper and lower makes progress drives flip-arm 3 to rotate around turnover bracket 7.Stabilizer rod 5 links into an integrated entity a pair of flip-arm 3 by welding, and when operator's compartment rolls, upper bracket 1 drives flip-arm 3 rotations, and the difference degree of the anglec of rotation is relevant to the side tilt angle of operator's compartment size.
