The specific embodiment
Below in conjunction with accompanying drawing and instantiation the utility model is made detailed description further.
As shown in the figure, comprise the preceding wheel assembly 1 of existing walker tractor, adopt hinge 2 to link to each other with trailer 3, the goods that trailer 4 transports in order to placement, trailer has rear wheel assembly 5 and rear driving axle 6 for 4 times; The hydraulic-driven part, the oil pump 11 that links to each other with walker tractor change speed gear box 7 is arranged, trailer 3 is provided with distributing box 14 and fuel tank 16, distributing box 14 is connected with control lever 13, control lever 13 replaces on position retaining plate 12, and HM Hydraulic Motor 15 connects back axle 6 and drags rear wheel assembly 5 motions, and hydrostatic drive is by the high pressure hose contact, control lever 13 affects steel wire backguy 34 operations, realizes advancing, retreat, dallying of trailer 3 by control lever 13; The utility model adopts the hydraulic-driven operation to constitute, be provided with the auxiliary facility of HM Hydraulic Motor, the utility model is characterised in that, on the semiaxis 21 of the rear driving axle 6 of trailer 3, be provided with diff 22, the motor key axle 24 of HM Hydraulic Motor 15 rotates, be fixed with forward gear gear 25 and backward gear gear 26 on the motor key axle 24, it accepts the position operation of control lever 13 at position retaining plate 12, flower wheel 23 on the semiaxis 21 is meshing with forward gear gear 25, perhaps in 26 engagements of backward gear gear, perhaps flower wheel 23 does not mesh,, reach the action of advancing, retreat, dallying of trailer 3; This operation is that nationality helps steel wire backguy 34 to realize, steel wire backguy 34 affects its gearshift position of shifter bar 35 realizations, spring 36 has balance, resets, the tension effect, bearing 31 is used for the ratchet running, reduces resistance of motion and friction, is provided with gear self-locking spring 33 on ratchet sleeve, be pressed with gear self-locking steel ball 32 under it, be provided with three gear limited pits 30 on motor key axle 24, gear self-locking steel ball 32 can fall into, and advances, retreats or the needs that dally to adapt to gearshift trailer 3; Slidably flywheel 40 is arranged on motor key axle 24, be provided with ratchet 41, ratchet 42, ratchet spring 43 in it.
The utility model working process is as follows:
When running into abrupt slope and muddy highway section, at first the tractor clutch is drawn back, change speed gear box 7 and oil pump 11 cut, the control lever 13 of trailer 3 is suspended to forward gear, 13 pullings of control lever steel wire backguy 34, the forward gear gear 25 that affects the shifter bar 35 on the rear driving axle 6 to stir on the motor key axle 24 is suspended on the flower wheel 23, connects oil circuit, change speed gear box 7 hangs up gear, wheel assembly 1 front-wheel rotates before the loosen the clutch, trac., and oil pump 11 starts, HM Hydraulic Motor 15 work drag trailer 3 and move ahead; Because the rotating speed of wheel assembly 1 front-wheel before the rear wheel rotation speed of rear wheel assembly 5 is lower than, flywheel 40 effects in the rear driving axle 6 in the forward gear gear 25, make the trailing wheel of rear wheel assembly 5 not obtain the power of HM Hydraulic Motor 15, still rotate by the front-wheel of wheel assembly 1 before the trac. and walk, its operation and general walker tractor are without any distinguishing on the function, when running into climbing or muddy highway section, front-wheel skids, slow down or when not walking, then there is the rear wheel rotation speed of rear wheel assembly 5 to descend, ratchet 41 slippage no longer forward of flywheel 40 in the forward gear gear 25 on the motor key axle 24 of HM Hydraulic Motor 15, ratchet 42 and ratchet 41 engagements drive flower wheel 23 and diff 22 and semiaxis 21 rotates, and rear wheel assembly 5 trailing wheels are rotated, thereby realization four wheel drive, car load are to overtake; After abrupt slope or muddy highway section, the front-wheel of preceding wheel assembly 1 no longer skids, and the speed of a motor vehicle is accelerated, and the rear wheel rotation speed of rear wheel assembly 5 is accelerated, flywheel 40 begins action again, car load cruising, forward gear gear 25 no longer rotate, and flower wheel 23 no longer rotates, no longer affect the trailing wheel of rear wheel assembly 5 to rotate, with saving in power, then can stop oil pump 11 and HM Hydraulic Motor 15 this moment, thereby reduce consumption of power.
