Description
Technical field
The utility model relates to a kind of drag reduction covers, relate more specifically to a kind of for cargo or the Containerizable Cargo tailstock
The drag reduction cover of portion's adjustable-angle formula.
Background technique
Correlative study shows that the 60% of fuel oil power be used to overcome pneumatic resistance when lorry travel speed is 80Km/h
Power, and most aerodynamic drags are generated by tail portion, therefore, optimize the tail structure of lorry, for reducing aerodynamic drag, are improved
Fuel economy, response national energy-saving environmental protection are advocated, and have real value and meaning.
The deficiencies in the prior art are: being generally the fixed of bolt etc between the end plate and end face of existing drag reduction cover and connect
It connects, needs to reset bolt and be just adjustable angle, disassembly is inconvenient, and adjusts limited angle.This patent be intended to can directly by by
The running of key control hydraulic stem, to adjust the angle between end plate and end face.
Utility model content
Purpose of utility model: purpose of the utility model is to solve the deficiencies in the prior art, provide a kind of for compartment
The drag reduction cover of formula lorry or container carrier tail portion adjustable-angle formula, the cover adjustable range are wide, simple without disassembly, operation
Just.
Technical solution: in order to achieve the goal above, a kind of truck tail adjustable-angle formula described in the utility model
Drag reduction cover, it includes end face, end plate, rod piece, connecting rod and hydraulic stem, and the end plate is connect by hinge with end face, rod piece
Both ends be connected respectively with end face and end plate, connecting rod links together two rod pieces, and one end of hydraulic stem is fixed on end face,
One end of hydraulic stem is connected with connecting rod.
As the further preferred of the utility model, one end of the rod piece is connected by hinges with end face, separately
One end is connected by hinges with end plate.
As the further preferred of the utility model, the both ends of the hydraulic stem pass through hinges (6) and end respectively
Face is connected with connecting rod.
As the further preferred of the utility model, the end plate is mounted on the edge side of end face.
As the further preferred of the utility model, the quantity of the end face is two.
As the further preferred of the utility model, the end plate with a thickness of 2mm~5mm.
As the further preferred of the utility model, the angle between the end plate and end face is 0 °~90 °.
As the further preferred of the utility model, the hydraulic stem, which is connected and is passed through with hydraulic cylinder, drives indoor behaviour
Control platform controls and makes its work, can the directly operation button completion in driver's cabin by driver.
As the further preferred of the utility model, the end face is mounted on the tail portion of vehicle.
Working principle: the aerodynamic drag of cargo or container carrier in the process of moving by lorry front end and tail portion
Pressure drag formed, relative to front end, most pressure drags is generated by tail portion, and the generating source of tail portion aerodynamic drag
In its biggish separation eddy, the formula drag reduction cover can directly in driver's cabin control button to control the running of hydraulic stem,
The angle between end plate and end face is adjusted, so that the traveling incoming air preferably biggish separation eddy in cutting car tail portion, reduces
Tail end face negative pressure region area, to reduce front and back pressure drag.
The utility model has the advantages that described in the utility model a kind of for cargo or container carrier tail portion adjustable-angle formula
Drag reduction cover have the advantage that compared with prior art
A kind of drag reduction cover of truck tail adjustable-angle formula described in the utility model, compared with prior art, tool
It has the advantage that
1, the range of adjustable-angle is 0 °~90 °, and adjustable range is wide；
2, when not using drag reduction cover, end plate is shrinkable to be parallel to end face, has without disassembly；
3, drag reduction cover structure described in the utility model is simple, stable and reliable in work without disassembly, easy to operate.
