The gear installed on input drive shaft is engaged with the gear on the mainshaft. The non-shelled differential unit is installed to the mainshaft via spline. The shaft holes is left or right semi-shaft gear is matched with the mainshaft in slide mode and their external cylindrical gears are respectively engaged with the gears on two parallel drive shafts of back wheels. The drive shaft of rear wheels are linked to the drive shafts of front wheel via clutch. It can prevent skid of wheels.
Description
Technical field: the invention belongs to the improvement of self-propelled vehicle differential driver, particularly differential independent unit for individual 4 drivers of moto-driven vehicle.
Background technology: China is large agricultural country, and agricultural is progressively realizing mechanization production, and trac. is the main member in the field machine.At work, require the dilatory multiple ground-surface ploughing work of functional adaptation, and can operate by cruising, have good through performance.Present four-wheel drive tractor is the form by the four wheel drive of two differential controls vehicles, and the oad of its auxiliary gear box is excessive, has limited the ground Clearance, influences the through performance of vehicle.When trac. travelled on abominable road surface, wheel often skidded, and tractive force descends, and made the vehicle can't cruising, and its complex structure, the manufacturing cost height.
Summary of the invention: the object of the present invention is to provide a kind of differential independent unit for individual 4 drivers of moto-driven vehicle, wheel was non-slip when trac. was travelled on abominable road surface, turned to freely, guaranteed normal vehicle operation; And simple in structure, the auxiliary gear box oad is little, increases the ground Clearance, improves the through performance of vehicle.
The object of the present invention is achieved like this: a kind of differential independent unit for individual 4 drivers of moto-driven vehicle, comprise diff, input shaft gear drives input shaft by transmission system and rotates, the gear of installing on the input shaft is meshed with gear on the main shaft, no shell-type diff is installed on the main shaft by spline, its left side, the axis hole of right axle shaft gear respectively with the main shaft bearing fit, a left side, the outer cylinder gear of right axle shaft gear is meshed with gear on two back-wheel drive axles that are installed in symmetrical parallel respectively, and the opposite side of two back-wheel drive axles is connecting two front wheel driving shafts by arrangement of clutch respectively.
Two arrangement of clutch of the present invention by symmetry couple together two back-wheel drive axles and two front wheel driving shafts of symmetrical parallel setting, finally output power in the corresponding front and rear wheel side reducer, come powered vehicle to travel and advance.Having realized that the homonymy wheel links, is to rotate with speed.The wheel of both sides allows to exist velocity contrast like this, therefore, can not influence the turning efficiency of vehicle, makes vehicle can accomplish to turn to freely.
When vehicle of the present invention being installed travelling on normal road surface, handle arrangement of clutch and two back-wheel drive axles are thrown off with two front wheel driving shafts respectively is connected, at this moment, the form of vehicle employing back-wheel drive is travelled.When vehicle ' is on abominable road surface, handles arrangement of clutch two back-wheel drive axles are connected with two front wheel driving shafts respectively.So just realize four wheel drive, and the homonymy wheel just turns round together with speed.When a tyre skidding, the power of other three wheels still exists, and vehicle can cruising.When with two tyre skiddings on drive axle or the diagonal line, because of the homonymy wheel links, the power of slip wheel can not increase because of the reduction of slip wheel power.In this case, vehicle still can cruising.Strengthened the earth-catching property of wheel, wheel is non-slip when carrying out farmland operation and transportation, turns to freely, and the power of driving engine has obtained giving full play to.
Because the present invention is simple in structure, adopt the auxiliary gear box of four wheels of a diff driving, reduced the oad of auxiliary gear box, increased the ground Clearance, improved carrying capacity.
Description of drawings: Fig. 1 is a sectional structure scheme drawing of the present invention, and Fig. 2 is the A-A sectional structure scheme drawing of Fig. 1.
The specific embodiment: the present invention is described in further detail below in conjunction with accompanying drawing.A kind of differential independent unit for individual 4 drivers of moto-driven vehicle comprises diff, and by change speed gear box output two-way power, one road power input shaft 16 is used to transmit independently outputting power, to satisfy at present or the job requirement of multiple advanced farm implements later on.Another road is then by input shaft gear 1 input auxiliary gear box, one end of input shaft 4 is installed in the axis hole of input shaft gear 1 by bearings, its other end is installed on the bearing seat, input shaft gear 1 drives input shaft 4 by transmission system and rotates, the gear of installing at the opposite side of input shaft 43 is meshed with the gear 11 on the main shaft 8, to be input shaft gear 1 be meshed with big gear wheel by the big or small compound gear 15 of bearing installation on main shaft 8 transmission system, middle part at input shaft 4 is installed with slip compound gear 2 by spline, and slip compound gear 2 has internally toothed annulus and outer cylinder gear; Be positioned at the right side of input shaft 4 when slip compound gear 2, the miniature gears of the big or small compound gear 15 by bearing installation on its outer cylinder gear and the main shaft 8 is meshed, when slip compound gear 2 is positioned at the left side of input shaft 4, its internally toothed annulus is meshed with input shaft gear 1.By fork controls slip compound gear 2 respectively with the pinion of input shaft gear 1 or big or small compound gear 15, make input shaft 4 obtain different rotating speeds.No shell-type diff 6 is installed on the main shaft 8 by spline, its left and right half gear 5,7 axis hole respectively with main shaft 8 bearing fits, the outer cylinder gear of left and right half gear 5,7 respectively with two back-wheel drive axles 17,9 that are installed in symmetrical parallel on gear 12,10 are meshed, the opposite side of two back-wheel drive axles 17,9 is connecting two front wheel driving shafts 14 by arrangement of clutch respectively, and annotate: the label of two front wheel driving shafts all is 14.Arrangement of clutch is for by the spline overriding clutch on companys of being installed in a back-wheel drive axle 17,9 and two front wheel driving shafts 14 respectively, and overriding clutch is unidirectional wedge-typed overrunning clutch or the roller clutch of rubbing; As shown in Figure 1, wherein the axle sleeve of the shell 13 of roller clutch is installed in respectively on two back-wheel drive axles 17,9 by spline, and star-wheel 18 is installed in respectively on two front wheel driving shafts 14 by spline; When adopting unidirectional wedge-typed overrunning clutch, its star-wheel is installed in respectively on two back-wheel drive axles 17,9 by spline, and the axle sleeve of shell is installed in respectively on two front wheel driving shafts 14 by spline; Vehicle is in operation, when front-wheel skids or when front wheel rotation speed was greater than the rotating speed of back-wheel drive axle during Vehicular turn, overriding clutch cut off the power that is transmitted by front-wheel automatically, is that parasitic horsepower does not take place whole drive system.When vehicle ' during at fair running road surface or downhill running, stir overriding clutch by shift fork, make two overriding clutchs disconnect being connected of rear drive shaft and front wheel driving shaft respectively, to improve driving efficiency.
The present invention has satisfied the every requirement of country to trac., has accomplished the interlock of wheel homonymy, has increased the ground Clearance, improved carrying capacity, strengthened the adherence properties of wheel, when carrying out farmland operation and transportation, wheel is non-slip, turns to freely, and the power of driving engine has obtained performance fully.
