Abstract
The utility model relates to a truck with high curb weight utilization factor, which is characterized in that parts of a bottom plate, an auxiliary frame, a carriage and a hydraulic dumping mechanism are made of high-strength materials for bearing large load. Sectional heights of parts made of plates are reduced effectively while integral strength of the truck is guaranteed, accordingly gravity center height and curb weight of the truck are reduced effectively, and load mass is increased. Compared with trucks using common plates, the high-strength plates can guarantee that the curb weight of the single truck is reduced by 1-2 tons while the sectional heights of the plates of the carriage are reduced by 20%, and the load mass of the truck is increased while the total weight is unchanged, thereby increasing single-trip capacity of the truck and bringing extra economic benefits. Further, the curb weight of the single truck is reduced, fatigue strength of other parts is reduced, the service lives of tires, plate springs, axles, transmissions and the like are prolonged, and transportation cost is saved greatly.
Description
Technical field
The utility model relates to a kind of automotive energy-saving emission-reducing field, is specifically related to a kind of high curb mass factor of utilization automobile.
Background technology
The degree of perfection of the parts of curb mass factor of utilization and automobile, assembly, structure and the Occupation coefficient of lightweight material are relevant, it shows the usage level of automobile main material, in the design that reflects automobile, manufacture level, also reflected the economy of automobile indirectly.In transportation, the automobile curb mass will cause unproductive oil consumption, quicken the loss of wear on tyres and engine power.Under the identical condition identical with service life of charge material amount of automobile, the curb mass factor of utilization is high more, and the structure of this vehicle and manufacture level are just high more, so the raising of curb mass factor of utilization is one of important symbol of modern goods carrying vehicle manufacturing technology progress.
Charge material amount requirement under identical curb mass improves day by day to automobile along with the demestic user in recent years, and domestic heavy depot through technical develop rapidly in the past few years huge variation is taking place all aspect vehicle and the product structure.According to the preliminary statistics, dumping car, the superimposed trailer of the annual repacking of China are about 300,000, if calculate for 5 tons with average each car, a year steel using amount should add other vehicle steels at 1,500,000 tons, and the steel demand is no less than 1,800,000 tons, is in great demand.Generally speaking, the curb mass of automobile whenever alleviates 10%, and fuel oil consumption can reduce by 6%~8%, year steel using amount 1,800,000 ton hours will save 2,250,000 liters of fuel oils.In order to reach the purpose of " energy savings cuts down the consumption of energy ", except constantly improving vehicle structure and manufacturing technology, the main path that reduces the curb mass of automobile is to utilize lightweight composite materials.
The utility model content
The utility model is at the deficiencies in the prior art, a kind of major part that high strength, lightweight material is applied to automobile has been proposed, not only can improve the structural strength of automobile, also can effectively reduce the automobile curb mass, improve the charge material amount, reduce the high curb mass factor of utilization automobile of centre of gravity of vehicle.
The technical solution of the utility model is as follows:
A kind of high curb mass factor of utilization automobile, it is characterized in that: it comprises subframe, compartment and hydraulic tipping gear, and described subframe is arranged on the end face of chassis, and described compartment is arranged on the subframe; Described subframe end face is provided with guide plate and carries out spacing to described compartment; Described hydraulic tipping gear is arranged between compartment and the headstock, and following of oil cylinder of described hydraulic tipping gear and described subframe are fixed, and described oil cylinder and described compartment are fixed near an end of headstock; The material that bears the position of big load in described subframe, compartment and hydraulic tipping gear is the high strength material of T610L, T710L and/or T810L for the intensity trade mark.
Described subframe comprises subframe longeron and chassis cross-member.
Described compartment comprises base plate and railway carriage or compartment plate.
The afterbody on described chassis is provided with the anti-holder of turning over.
The described structure member that bears big load also comprises following of oil cylinder, anti-holder, guide plate and the connecting arm of turning over.
Technique effect of the present utility model is as follows:
The utility model uses high strength material in the bigger loose mail of subframe, compartment, hydraulic tipping gear and the bearing load of automobile, outside the bulk strength that guarantees automobile, also effectively reduce the thickness of sheet material manufacturing part, thereby effectively reduce curb mass, improve the charge material amount, for example on base plate false longeron, floor beam, base plate body, railway carriage or compartment plate crossbeam and railway carriage or compartment plate longeron, use high-strength plate, sheet metal thickness is reduced.Compare with the automobile that uses common sheet material, high-strength plate can guarantee under the situation of compartment sheet metal thickness reduction by 20%, the curb mass of separate unit car can reduce the 1-2 ton, under total weight unmodified situation, improved the charge material amount of automobile, thereby improved single transport power of automobile, brought extra economic benefit.Because the curb mass of separate unit car reduces, will alleviate the strength at repeated alternation of other parts simultaneously, prolong the service life of tire, leaf spring, vehicle bridge, change speed gear box etc., save traffic cost greatly.Curb mass reduces the oil consumption that has also alleviated vehicle, 1 ton of the every minimizing of automobile curb mass, and fuel consumption of 100km just can reduce 1L, significantly reduces the oil consumption cost.
Owing to use high strength material, outside the bulk strength that guarantees engineering dump truck, also effectively reduce the depth of section of sheet material manufacturing part, thereby effectively reduce the height of gravitational center of car load, the safety that has improved vehicle '.For example on subframe longeron 1 and underframe longitudinal member 31, use high-strength plate, can reduce the depth of section of institute's workpieces.
Simultaneously, the part working strength trade mark is the high-strength panel of T610L, T710L and/or T810L in the compartment, improve 1 times with respect to the common trade mark for the Q235 timber intensity, anti-simultaneously surrender, shock resistance, anti-wear-resisting more than 1 times of common sheet material that reaches can prolong the car opertion life-span.
