Description

A kind of wide dumper

Technical field:

The utility model relates to haul truck technical field, is a kind of wide dumper specifically; Be applicable to the special occasions such as port and pier, glory-hole.

Technical background:

In the niche market such as port and pier, glory-hole, its transported material is relatively stable, operating mode is severe, vehicle hour is long, and common road dump truck, owing to being subject to the restriction of highway code and vehicle standard, is difficult to meet user demand; For this particular market, the wide dumper of exploitation at present, its load-carrying is large, the speed of a motor vehicle is low, intensity is high, more adapt to port and pier, this particular market of glory-hole, but it still exists larger deficiency than road dump truck:

1, existing wide dumper still adopts the technology platform of road dump truck, just carry out local improvement, do not carry out brand-new design, so existing wide dumper does not solve the problem that road dump truck occurs completely, and limited it and develop toward large-tonnage;

2, existing wide dumper generally adopts 375 horsepower engines, but that car load maximum total mass reaches 70t is even larger, has the problem of dynamic property deficiency; In order to improve operating efficiency, the engine long time is moved near maximum speed of revolution, causes breakdown in the motor rate high, and service life is short; In addition, the fuel consumption rate of driving engine in the time of high rotating speed is higher, causes vehicle oil consumption high, and economy is bad;

3, existing wide dumper generally adopts Manual transmission, but need often gearshift in the niche market such as port and pier, glory-hole, strengthened the manipulation strength of chaufeur, and because gearshift is frequent, make the fault rate of change speed gear box, power-transfer clutch very high, greatly shorten service life;

4, existing wide dumper generally adopts riveted joint vehicle frame, and the longeron of riveted joint vehicle frame is to be formed by steel plate punched, and its thickness generally, in 12mm, has also just determined that the rigidity of riveted joint vehicle frame is less than normal; In order to increase vehicle frame rigidity, how on vehicle frame, to increase a subframe, complex structure, and increased vehicle's center of gravity height, bad stability, easily causes the accidents such as overturning; In addition, vehicle frame rigidity is on the low side, in use easily occurs vehicle frame distortion, and serious meeting causes vehicle scrapping;

5, the forward mounting of existing wide dumper generally adopts steel spring structure, this structure have two significantly not enough: 1, leaf spring is as main load member and shock absorber part, stressed complexity, fault rate is high; The load change of 2, vehicle zero load, at full load propons is larger, and the steel spring adopting such as is at the rigidity, and while causing zero load, the oscillation frequency of vehicle is higher, and traveling comfort is poor;

6, the rear-mounted of existing wide dumper generally adopts the equalizing suspension system structure that steel spring is housed, and this structure exists significantly not enough: 1, leaf spring is as main load member and shock absorber part, stressed complexity, and fault rate is high; 2, vehicle in use, because road conditions are poor, road resistance coefficient is large, operation intensity is high, the phenomenon such as serious that overloads, often occurs propelling rod fracture, the distortion of propelling rod bulb causing the phenomenons such as middle back axle walks; 3, owing to having friction pair between leaf spring and middle back axle and positioning plate, and between positive pressure larger, cause in this structure existing larger friction force;

7, the steering swivel system of existing wide dumper generally adopts the integral automobile steering system of a large cylinder diameter, then adds an external steering actuation cylinder; But this kind of arrangement exists significantly not enough: 1, the working flow of Integral steering device is all generally 25 L/min at present, and operation pressure is 15MPa, has limited its application on large-tonnage vehicle; 2, this scheme output torque in the time turning left with right-hand rotation is different; 3, owing to there being two deficiencies above, also cause the fault rate of deflector higher; 4,, because weight on front axle is larger, this scheme, in the time that steering pump lost efficacy, can not provide emergent and turn to;

8, wide dumper is mainly engaged in a cubic meter overburden operation in mining area, and bottom plate wear is serious; And load stone when larger, and may be excessive because of the impact of stone, cause compartment distortion, have a strong impact on the life-span in compartment; For solving the deficiency of this two aspect, now many on cabin floor welding anti-ly pound bar, increase that thickness of slab etc. comes anti-ly to pound, the effect of abrasionproof, but this kind of way not only increased the complexity in compartment, increases cost, but also the deadweight that has increased vehicle, car load economy variation.
