Abstract
The utility model relates to semitrailer field, is the semitrailer of a kind of left-right telescopic, low flat board.It is characterized in that tire under gooseneck shape vehicle frame above have arc groove under vehicle frame, on air suspension, be connected with gooseneck shape vehicle frame, under air suspension, be connected with leaf spring; At gooseneck shape vehicle frame, be fixed with cross member of frame, in the left and right of cross member of frame, left hydraulic ram and right hydraulic ram are housed respectively, on left hydraulic ram, there is left sleeve, the cylinder body of left hydraulic ram is fixed on the left side of cross member of frame, the plunger rod of left hydraulic ram is connected with left sleeve, has left limit pin on left sleeve.Owing to having adopted the technical program, can the flexible goods table top in left and right, make carrying surface can be narrow can be wide; Vehicle frame is slope, arc gooseneck type structure, adopts air suspension structure, and is designed to arch formula at tire part frame, and the carrying surface terrain clearance of vehicle is less than 1 meter, and the center of gravity of vehicle is low, good stability.Can deliver various construction machinery and equipments, large-scale super wide equipment etc. again.
Description
Technical field
The utility model relates to semitrailer field, is the semitrailer of a kind of left-right telescopic, low flat board.
Background technology
Strengthen especially at present the control and management to overrun vehicle both at home and abroad, every country and area have all been formulated corresponding traffic law and have been alleviated the problems: as the width of any vehicle that comprises superimposed trailer travelling by day and institute's transporting cargo all can not surpass 2.5 meters, can not deliver various construction machinery and equipments, large-scale super wide equipment etc.Meanwhile, for the transport vehicle of the article such as household electrical appliances, articles for daily use, rubber, timber and timber-work, light cargo, have that center of gravity is high, poor stability, the drawback such as easily superelevation, transport benefits be low.
Summary of the invention
The purpose of this utility model is the semitrailer that a kind of left-right telescopic, low flat board will be provided.Left and right sleeve type hydraulic oil cylinder is housed on vehicle frame, and vehicle frame is slope, arc gooseneck type structure, and is designed to arch formula at tire part frame.
The technical solution of the utility model is: the semitrailer of a kind of left-right telescopic, low flat board, it is characterized in that tire under gooseneck shape vehicle frame above have arc groove under vehicle frame, on air suspension, be connected with gooseneck shape vehicle frame, under air suspension, be connected with leaf spring; At gooseneck shape vehicle frame, be fixed with cross member of frame, in the left and right of cross member of frame, left hydraulic ram and right hydraulic ram are housed respectively, on left hydraulic ram, there is left sleeve, the cylinder body of left hydraulic ram is fixed on the left side of cross member of frame, the plunger rod of left hydraulic ram is connected with left sleeve, has left limit pin on left sleeve; On right hydraulic ram, have right sleeve, the cylinder body of right hydraulic ram is fixed on the right side of cross member of frame, and the plunger rod of right hydraulic ram is connected with right sleeve, and right limit pin is housed on right sleeve.
Owing to having adopted technique scheme, can the flexible goods table top in left and right, make carrying surface can be narrow can be wide; Vehicle frame is slope, arc gooseneck type structure, adopts air suspension structure, and is designed to arch formula at tire part frame, and the carrying surface terrain clearance of vehicle is less than 1 meter, and the center of gravity of vehicle is low, good stability.Can deliver various construction machinery and equipments, large-scale super wide equipment etc. again.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of gooseneck shape vehicle frame cross-sectional plane of the present utility model.
In the drawings: 1, gooseneck shape vehicle frame; 2, air suspension; 3, arc groove under vehicle frame; 4, left sleeve; 5, left limit pin; 6, cross member of frame; 7, right hydraulic ram; 8, right sleeve.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is further described.
In Fig. 1 and Fig. 2, above the tire under gooseneck shape vehicle frame 1, there is arc groove 3 under vehicle frame, on air suspension 2, be connected with gooseneck shape vehicle frame 1, air suspension is connected with leaf spring for 2 times; At gooseneck shape vehicle frame 1, be fixed with cross member of frame 6, in the left and right of cross member of frame 6, left hydraulic ram and right hydraulic ram 7 are housed respectively, on left hydraulic ram, there is left sleeve 4, the cylinder body of left hydraulic ram is fixed on the left side of cross member of frame 6, the plunger rod of left hydraulic ram is connected with left sleeve 4, has left limit pin 5 on left sleeve 4; On right hydraulic ram 7, have right sleeve 8, the cylinder body of right hydraulic ram 7 is fixed on the right side of cross member of frame 6, and the plunger rod of right hydraulic ram 7 is connected with right sleeve 8, on right sleeve 8, right limit pin is housed.
Left hydraulic ram and right hydraulic ram 7 by both sides are flexible, drive respectively left sleeve 4 and the right sleeve 8 of both sides, along cross member of frame 6, slide cargo carrying platform is stretched both sides to the left and right, plug locating dowel pin 5 locking, simultaneously identical for guaranteeing the flow of hydraulic ram of left or right side, the sleeve that promotes respectively both sides with identical thrust does not produce twisted or stuck phenomenon during along cross beam movement, and the flow that a flow divider-combiner is controlled respectively two oil cylinders of the left and right sides is respectively housed in the hydraulic circuit of both sides.
