Description
Technical field
The present invention relates to dumping car technology, specifically a kind of a11wheel drive wide dumper used under highway road conditions.
Background technology
The area of south China, Southeast Asian countries and regions and similar tropical rainy climate and tropical monsoon climate, rainfall is frequent, the time in rainy season is long, and road surface is soft, muddy, and existing most of dumping car can not run in this muddy, soft road conditions.Existing dumping car, mainly contain two large classes, one class is the road dump truck of automobile category, another kind of is the haul truck of earthmoving machinery category, and haul truck is divided three classes: highway mechanical drive quarry tipper, highway electric transmission quarry tipper, highway mechanical drive wide dumper; Wherein articulated truck belongs to the one in highway mechanical drive quarry tipper, is mainly used in the transport of surface mine loose unpacked material.Above-mentioned two class dumping cars, mainly have the following disadvantages:
The road dump truck of automobile category, because of the restriction of highway code and vehicle standard, is difficult to meet the particular/special requirement of highway operating mode to vehicle well;
The highway mechanical drive wide dumper of earthmoving machinery category, it drives pattern to be 4X2 or 6X4, and easily skid and sunken car at muddy, soft surface, crossing ability is poor; Although the road worthiness of articulated truck and can operating needs be met by performance, its price and maintaining expense and oil consumption all very high, use less so actual.6X4 highway wide dumper, primarily of engine assembly, cooling system, front suspension, clutch assembly, transmission assembly, transmission shaft component, middle axle assembly, rear suspension, back axle assembly, subframe, main car frame, container, exhaust system, operator's compartment assembly and annex, steering swivel system, tire and wheel rim, front axle assembly, wing plate and bumper/spoiler, air system, container dump mechanism composition, it drives pattern to be that 6X4 drives, its front wheel tread and jackshaft and rear axle wheel are apart from different, and middle back axle tire is arranged as twins.
Highway mechanical drive wide dumper, by the limitation of its arrangement structure, the tire maximum specification used at present is 16.00-25, and diameter of tyres is 1490mm, and the section width of tire is 430mm, the road clearance of its car load is 380mm, the grounding pressure of its tire is large, and road clearance is little, owing to not being a11wheel drive, easily skid and sunken car at muddy, soft surface, the crossing ability of vehicle is poor.
Summary of the invention
For highway mechanical drive wide dumper, exist under muddy, the soft working condition of highway state and skid and the inadaptability of sunken car, the object of this invention is to provide and a kind ofly fully can meet a11wheel drive highway wide dumper that is soft, muddy road surface applying working condition.
