Description
Technical field
The present invention relates to dumper technology, specifically a kind of a11wheel drive expanded letter used under off-highway road conditions is certainly
Unload.
Background technology
The area of south China, Southeast Asian countries and regions and similar tropical rainy climate and tropical monsson climate, rainfall
Frequently, the time in rainy season is long, and road surface is soft, miriness, and existing most of dumpers can not be transported in this muddy, soft road conditions
OK.Existing dumper, mainly there is two major classes, and a class is the road dump truck of automobile category, and another kind of is earthmoving machinery category
Haul truck, and haul truck is divided into three classes：Off-highway machine driving quarry tipper, off-highway electric transmission
Quarry tipper, off-highway machine driving wide dumper；Wherein articulated truck belongs to the mining self-unloading of off-highway machine driving
One kind in car, is mainly used in the transport of surface mine loose unpacked material.Above-mentioned two classes dumper, is primarily present following deficiency：
The road dump truck of automobile category, because of the limitation of highway code and vehicle standard, it is difficult to meet well off-highway
Particular/special requirement of the operating mode to vehicle；
The off-highway machine driving wide dumper of earthmoving machinery category, it is 4X2 or 6X4 that it, which drives pattern, in muddy, pine
Terrain surface easily skids and sunken car, poor by property；The road worthiness of articulated truck and although disclosure satisfy that by performance makes
With requiring, but its price and maintaining expense and oil consumption are all very high, so actually used less.The off-highway expanded letters of 6X4 are certainly
Unload, it is mainly total by engine assembly, cooling system, front suspension, clutch assembly, transmission assembly, transmission shaft component, jackshaft
Into, rear suspension, rear axle assy, subframe, main car frame, container, gas extraction system, drive chamber assembly and annex, steering, tire
And wheel rim, front axle assembly, wing plate and bumper, gas handling system, container dumping mechanism composition, it drives pattern to be driven for 6X4, its
Front tread is with jackshaft and rear axle wheel away from difference, and middle back axle tire is arranged as twins.
Off-highway machine driving wide dumper, is limited to by its arrangement structure, and used tire is maximum at present
Specification is 16.00-25, and diameter of tyres is 1490mm, and the section width of tire is 430mm, and the minimum ground clearance of its vehicle is
380mm, the grounding pressure of its tire is big, and minimum ground clearance is small, due to not being a11wheel drive, easy in muddy, soft surface
Skid and sunken car, vehicle it is poor by property.
The content of the invention
For off-highway machine driving wide dumper, exist under muddy, the soft working condition of off-highway state and beat
The inadaptability of sliding and sunken car, can fully meet soft, muddy road surface applying working condition it is an object of the invention to provide a kind of
The off-highway wide dumper of a11wheel drive.
The technical scheme is that：
The off-highway wide dumper of a11wheel drive of the present invention, on the basis of the off-highway wide dumpers of 6X4, is added
Steer drive front-axle, transfer gear suspension, transfer case assembly.Its operation principle is：Vehicle is on soft, heavy road face or in nothing
, it is necessary to increase the number of driving wheel when being travelled in the case of road, to make full use of the weight of vehicle to increase between wheel and road
Adhesive force, transfer case assembly be arranged on transmission assembly behind, be connected with transmission shaft component with transmission assembly, its effect is
The moment of torsion that speed changer is transmitted distributes to each drive axle（Steer drive front-axle, middle axle assembly and rear axle assy）.
