Abstract
The utility model discloses a back four-wheel full driving mechanism of a middle or small load-carrying vehicle, comprising a drive shaft, a first drive bridge, a first primary reduction box, a first back cover, a transmission shaft, a second drive bridge, a second primary reduction box and a second back cover. The drive shaft passes through the first primary reduction box, the first drive bridge and the first back cover in turn to connect onto one end of the transmission shaft, and the other end of the transmission shaft is connected with a reducing mechanism of the second primary reduction box and the second drive bridge in a driving way. A gear mechanism capable of transferring power of the drive shaft to a reducing mechanism of the first primary reduction box is arranged inside the first primary reduction box, and the reducing mechanism of the first primary reduction box is connected with the first drive bridge in a driving way. The utility model adopts the technical solution, and the back four wheels all transfer power, thereby greatly increasing stability of the vehicle on wet icy roads, muddy roads and rough roads, and the back four-wheel full driving vehicle can climb steeps where back two-wheel driving vehicles can not reach.
Description
Technical field
The utility model relates to the full drive configuration of back four-wheel of middle-size and small-size load-carrying vehicle.
Background technology
Middle-size and small-size load-carrying vehicle is meant that load carrying ability is the bogie below 10 tons, and its power is connected with the deceleration assembly of back axle by transmission shaft through change speed gear box, realizes power transmission.Its back axle generally has only the mechanism of two-wheel drive, and on wet and slippery ice and snow, muddy road surface and uneven road surface, trailing wheel skids through regular meeting, and the crossing ability of vehicle and climbing property are relatively poor.
The utility model content
The purpose of this utility model is to provide a kind of can effectively prevent rear wheels slip, improves the full drive configuration of back four-wheel of the middle-size and small-size load-carrying vehicle of the crossing ability of vehicle and climbing property.
The technical solution of the utility model is such: the full drive configuration of back four-wheel of middle-size and small-size load-carrying vehicle comprises imput shaft, first drive axle, first main reduction gear, first bonnet, transmission shaft, second drive axle, second main reduction gear and second bonnet; Above-mentioned imput shaft connects an end that passes above-mentioned first main reduction gear, above-mentioned first drive axle and above-mentioned first bonnet and be connected to above-mentioned transmission shaft successively, and the other end of above-mentioned transmission shaft is in transmission connection with the speed reduction gearing of above-mentioned second main reduction gear, above-mentioned second drive axle successively; Being provided with in above-mentioned first main reduction gear can be with the transmission of power of the above-mentioned imput shaft gear mechanism to the speed reduction gearing of above-mentioned first main reduction gear, and the speed reduction gearing of above-mentioned first main reduction gear and above-mentioned first drive axle are in transmission connection.
Said gear mechanism comprises back axle gear, transition gear and the driving gear that is meshed successively, and the spline of above-mentioned back axle gear is connected on the above-mentioned imput shaft, and the speed reduction gearing of the wheel shaft of above-mentioned driving gear and above-mentioned first main reduction gear is in transmission connection.
After adopting such scheme, the full drive configuration of back four-wheel of middle-size and small-size load-carrying vehicle of the present utility model, because the back four-wheel is transferring power all, improved vehicle so greatly at wet and slippery ice and snow, muddy road surface and uneven ground-surface crossing ability, simultaneously the four-wheel full vehicle that drives in back can be climbed up back two-wheel drive vehicle and be climbed the abrupt slope of not getting on.If having added propons drives, form one six drive system, will 1, improve crossing ability and climbing property greatly: 2, provide splendid turning performance: adhesion of tyres has confidential relation with the power size that transfers to road, and with the increase of power, the lateral control force of tire trend reduces.Power reduces, and lateral control force raises, the performance when improving wet and slippery road surface and lane change; 3, provide splendid startup and acceleration capability: the vehicle that front and back wheel drives, engine power on average is passed to all six wheels, and the adhesive ability of six wheels can be used effectively.Even floor so will speed up pedal suddenly, wheel also can not dally, thereby has improved the startup and the acceleration capability of vehicle; 4, straight motion stability: because the rising of the residue adhesive ability of each wheel, so the ability of the anti-external disturbance of wheel is enhanced.Therefore six-wheel drive demonstrates superior directional balance.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the axial local cut-away enlarged view of imput shaft in the utility model.
The specific embodiment
The full drive configuration of back four-wheel of middle-size and small-size load-carrying vehicle of the present utility model as shown in Figure 1, 2, comprises first main reduction gear 1, first drive axle 2, first bonnet 3, transmission shaft 4, second main reduction gear 5, second drive axle 6, second bonnet 7 and imput shaft 8; Imput shaft 8 connects an end that passes first main reduction gear 1, first drive axle 2 and first bonnet 3 and be connected to transmission shaft 4 successively, the end that imput shaft 8 is stretched out first main reduction gear 1 is provided with flange 81, the other end that imput shaft 8 is stretched out first bonnet 3 is provided with flange 82, imput shaft 8 is connected with transmission shaft 4 by flange 82, and the other end of transmission shaft 4 is in transmission connection with flange, second drive axle 6 of second main reduction gear 5 successively; Be provided with back axle gear 13, transition gear and the driving gear 14 that is meshed successively in the housing 12 of first main reduction gear 1 (housing 12 is integrally casting moulding), the spline of back axle gear 13 is connected on the imput shaft 8, and driving gear 14 is in transmission connection with speed reduction gearing 15, first drive axle 2 of first main reduction gear 1 successively.During work, power is delivered to imput shaft 8 through flange 81, is delivered to transmission shaft 4 through flange 82 again, passes through transmission shaft 4 then with the speed reduction gearing of transmission of power to second main reduction gear 5, and finally the speed reduction gearing by second main reduction gear 5 drives second drive axle 6; Give transition gear by back axle gear 13 transferring power that are socketed on the imput shaft 8 simultaneously, give driving gear 14 by transition gear with transmission of power again, give the speed reduction gearing 15 of first main reduction gear 1 by driving gear 14 with transmission of power again, finally realize the driving of first drive axle 2 by the speed reduction gearing 15 of first main reduction gear 1.
The utility model redesigns the housing of first main reduction gear, by gear mechanism, makes doube bridge drive simultaneously, and the hand of rotation unanimity, need not other retarder.Imput shaft connects passes bonnet, transferring power.The rest may be inferred, can realize the driving of three bridges or even four bridges, five bridges, forms three, the through-drive axle of tetrad, 5-linked.
