Description
One, technical field
The utility model is the long wheelbase superimposed trailer that a kind of goods transport is used.
Two, background technology
The semitrailer wheel space of present domestic use is many below 1350mm; Under the requirement of state compulsion standard GB1589, for selected vehicle type, its maximum autohrozed total mass and contour dimension are defined, under the situation of existing wheelbase, the distance between the towing pin and first reach is bigger, to the intensity of vehicle frame very high requirement will be arranged, this must increase the thickness of vehicle frame beam slab, thereby increase the weight of vehicle frame, reduced capacity weight, reduced charge material amount factor of utilization.
Three, summary of the invention
The purpose of this utility model is that the transportation for goods provides a kind of long wheelbase superimposed trailer.It is simple in structure, has reduced the thickness of vehicle frame beam slab, has increased capacity weight, has improved conveying efficiency, has increased the active area of tire road pavement, reduces the Tyte Wear amount.
For achieving the above object, the technical solution adopted in the utility model is: having designed wheelbase is the suspension assembly of 1400～1900mm, the distance of first reach and towing pin is reduced, the reach of carrying center of gravity, can reduce requirement of strength to chassis side rail, reduce the thickness of vehicle frame beam slab, increased capacity weight; Designed the suspension assembly of forming by support, spring plate, equalizing bar, connecting rod; Specifically the utility model includes frame assembly, towing pin, suspension assembly, supporting leg, vehicle bridge and tire assembly, guard rail, brake assembly, electric assembly etc.; Towing pin is contained in the front end of frame assembly, supporting leg is contained in the front portion of frame assembly downside, vehicle bridge and tire assembly are contained in frame assembly rear portion downside by suspension assembly, vehicle bridge and tire assembly are provided with brake assembly, electric assembly is contained on the frame assembly, and guard rail is contained in the sidepiece and the rear portion of frame assembly downside; The wheelbase that it is characterized in that suspension assembly is 1400～1900mm.
The version of suspension assembly is a lot, can include equalizing bar, balance shaft, pull bar, connecting rod, bracket I, bracket I I, plate spring assembly, spring block; Equalizing bar, balance shaft are two, bracket I, bracket I I are fixed on the frame assembly downside of superimposed trailer, bracket I is in the front side of bracket I I, equalizing bar is equipped with by balance shaft respectively in the lower end of bracket I, bracket I I, the equalizing bar of bracket I downside connects with the plate spring assembly of front side, and the equalizing bar of bracket I I downside connects with the plate spring assembly of rear side; Length-adjustable connecting rod is housed between two equalizing bars, and connecting rod and equalizing bar are articulated lifting arm; One end of pull bar and bracket I I articulated lifting arm, the other end and be fixed on the spring block articulated lifting arm of rear side plate spring assembly lower end, plate spring assembly is fixed on the vehicle bridge of superimposed trailer vehicle bridge and tire assembly by the spring block of lower end.
Because suspension assembly of the present utility model design has length-adjustable connecting rod, and structure has been carried out suitable improvement, make the wheelbase of suspension assembly can be by increasing to 1400～1900mm below the original 1350mm.To the superimposed trailer of maximum autohrozed total mass, towing pin is under one stable condition of frame assembly position, and what assembling had a long wheelbase is suspended in the frame assembly rear portion, makes the reach of carrying center of gravity; Therefore it is simple in structure, has reduced the thickness of vehicle frame beam slab, has increased capacity weight, has improved conveying efficiency, has increased the active area of tire road pavement, reduces the Tyte Wear amount.
Characteristics of the present utility model:
1, because the utility model has designed the suspension of realizing having long wheelbase by the length that changes equalizing bar and connecting rod, particularly realize this method of long wheelbase by changing length of connecting rod, can realize being assembled into the suspension assembly that wheelbase is 1400～1900mm, make the reach of carrying center of gravity widely, increased capacity weight.
2, because the utility model has designed the suspension assembly of long wheelbase, increased the active area of tire road pavement, reduced the Tyte Wear amount, made the application force between tire and the road surface more reasonable, vehicle ' is more stable.
Four, description of drawings
Fig. 1 is the utility model scheme drawing;
Fig. 2 is the suspension assembly scheme drawing.
Five, specific implementation method
Accompanying drawing is an embodiment of the present utility model, is three and adorn the long wheelbase container transport semi-trailer, includes frame assembly 2, towing pin 1, suspension assembly 6, supporting leg 3, vehicle bridge and tire assembly 5, guard rail 4, brake assembly, electric assembly etc.; Towing pin 1 is contained in the front portion of frame assembly 2, supporting leg 3 is contained in the front and rear part of frame assembly 2, suspension assembly 6 is contained in frame assembly 2 rear portions, vehicle bridge and tire assembly 5 are contained on the suspension assembly 6, brake assembly is contained on vehicle bridge and the tire assembly 5, electric assembly is contained on the frame assembly 2, and guard rail 4 is contained in the sidepiece and the rear portion of frame assembly 2.
