Description

A kind of off-highway self-discharging vehicle that reduces wear, improves the leaf spring life-span

Technical field

The present invention relates to the dumping car that a kind of non-highway operating mode is used, especially a kind of can under non-highway operating mode situation, in various open cast mine material short distance transition transportations, the performance high transportation a kind of of usefulness and reduce wear improved the off-highway self-discharging vehicle in leaf spring life-span.

Background technology

At present, for similar site's these particular markets of loose unpacked material transportation such as domestic water conservancy power construction building site, glory-hole, the camp site relative closure, the duration is longer, and transported material is relatively stable, the vehicle working strength is big, upgrades fast.The mining car of engineering category is more suitable, but because of its acquisition cost and operating cost height, contracting of project unit needs purchase to be used for qualification certification on a small quantity for bid, the actual use seldom; The engineering truck of automobile category, on business road rules and vehicle standard restriction is difficult to the fine specific (special) requirements of satisfying the engineering operating mode to vehicle.Its deficiency point is main to be showed as follows:

1, the non-road vehicle of tradition use still improves with the just part that car is designed with by the engineering of standard basically, does not carry out the unit design layout according to need of real project.

2, traditional engineering is with in the car rear suspension; Use saddle clamp that Multi-Leaf Springs is installed in the balance shaft housing groove; Two ends are installed on the leaf spring slide plate chair on the bridge, and load-carrying is passed to subframe, vehicle frame, leaf spring to bridge and tire through container with power, Zhongdao ground.Steel spring is main load member and shock absorber part in suspension frame structure, causes the leaf spring rapid wear easily.In engineering truck uses,, improve the load-carrying capacity of vehicle simultaneously owing to limited by domestic heat treatment integral level; If the Multi-Leaf Springs thickening is too many, crack formed during heat-treatment can appear, can reduce elasticity simultaneously; Engineering truck goes and uses at uneven road surface like this; Cause vehicle to jolt seriously, steel spring is easily broken, and driver's labour intensity increases.

3, traditional engineering uses car back balance suspension propelling rod to adopt upper thrust rod vertically to distribute as single pole, and lower thrust rod is that two bar splayeds distribute.When this vehicle uses on-site; Because the building site road conditions are poor, the soft strong degree in vehicle ' road surface is poor, and surperficial road resistance coefficient is big; The high overload of operation intensity is serious; The upper thrust rod phenomenon of rupture often occurs, cause for a long time that drive axle walks, middle rear axle propeller shaft damages phenomenon, this suspension propelling rod distribution mode can not satisfy the building site and use.

4, traditional balance suspension all is the veneer spring structure, is about to the leaf spring center fixed on a balance shaft.Two end supports is delivered to power on the ground through the tire on the vehicle bridge on former and later two vehicle bridge again.This balance suspension is can be well with the power mean allocation on former and later two wheels, thereby is used widely.But along with continuing to increase of carload lot, this traditional veneer spring balance suspension can not well solve the contradiction under the unloaded and fully loaded two kinds of service conditions of vehicle.Be under the no-load condition, the total mass ratio of vehicle is less, and it is too big that the rigidity of leaf spring seems, the chaufeur difficult handling; And the total mass ratio of vehicle is bigger under the heavily loaded situation, and the rigidity of leaf spring seems too little.

5, traditional engineering is with in the car rear suspension, and drive form is the engineering truck of 6X4, and mostly rear suspension is the steel spring balance suspension, is connected with the whole machine balancing axle between leaf spring and the vehicle frame and realizes.The problem that exists is that noise is big, Heavy Weight, and the economic performance of vehicle is bad.

6, traditional engineering with car oil cylinder connection mode be support direct connection with the oil cylinder two ends on the container header board, such connection mode has three shortcoming: one, be the hole of on the container header board, boring 12 φ 16.5, because container header board weight is heavier; Area is very big; Processing is got up very inconvenient, and two, be because container header board easy deformation when the container lade so just directly causes the oil cylinder installation site to change; Make oil cylinder receive extra subsidiary load, reduce oil cylinder service life; Three, be because bolt directly links to each other with the container header board, make bolt cap be exposed at container the inside outward, receive after the goods shock effect to be difficult to dismantle after distortion or the corrosion, be not easy to the oil cylinder maintain and replace.

7, the investigation of a large amount of operating modes shows, for peeling off or the building sites such as exploitation of metallic ore of open coal mine, and once nearly more than 50 ton of the cargo-carring material of container; Container is in the lifting discharge process; Bigger to container upset free bearing device impulsive force, if insufficient strength or unreasonable structure are prone to cause upset free bearing cracking to have or gap increase; Cause container left and right sides play, therefore can damage elevating ram or cause roll-over accident.

8, the investigation of a large amount of operating modes shows: for peeling off or the building sites such as exploitation of metallic ore of open coal mine, the density of Loaded goods is greater than 1.8 tons/side, and thing grain diameter is greater than 500 millimeters; Loading facilities is big bucket capacity digging machine, loader or power shovel; This operating mode is for the big and serious wear of impulsive force of container, container easy of crack, distortion, particularly base plate easy deformation, cracking; Repair cost height and repairing efficiency is long, maybe can't repair and scraps.

9, original vehicle is in operation; Because ground-surface cheat recessed injustice cause vehicle vibrations, jolt; If the goods of dress is more in the container, the material that stows is skipped the container side plate and is dropped on the road surface of vehicle ', like the hail of pebbles used on the engineering on the road surface; Can damage vehicle tyre, reduce the service life of tire.

10, traditional engineering is with in the car rear suspension, and the leaf spring slide plate chair has dual mode, and a kind of is tower structure, can be from spacing in balance suspension, when back axle is beated, and be the plane but go up the plane, there is not oil groove with arc surface at present; Another kind is a reaping hook formula structure, and last plane is the plane, can not be from spacing when middle back axle is beated.Because in non-highway operating mode, the vehicle ' road surface is the engineering sidewalk, road conditions are poor; It is big that recessed out-of-flat is cheated on the road surface, and the axle tramp amount is big and frequent, and two kinds of structures of traditional like this leaf spring slide plate chair are used and the plane when non-highway operating mode, can be occurred on the spring block and under vehicle bridge, jump and when spacing, contact with the leaf spring line and be hit; The leaf spring increase that is stressed; Simultaneously lower plane does not have oil groove, causes the longest 3 of leaf spring like this, weares and teares with the leaf spring slide plate chair below; Be hit above, lengthy motion picture uses in the building site and is easy to fracture.
