Described change-speed gearing is provided with the manual control selector fork parts that can make the change-speed gearing move left and right; And the steering cluth spline gear is provided with the clutch displacement fork that is turned to by Driven by Hydraulic Cylinder, arrange two Multi-plate Wet Friction Clutch on steering clutch shaft, and they disposes the hydraulic jack that control turns to and brakes.
Two axletrees become same straight line about described, and each is arranged in parallel and is placed in the mould assembling formula casing by bearing respectively, and wherein driven wheel is placed in the casing by deep groove ball bearing.
The utility model compared with prior art has compact conformation, and handiness is flexible, technical indicator is advanced, uses reliably, and installation and maintenance are convenient, cost is low, and " three change " degree height of main parts size can satisfy the characteristics such as crawler type infinitely variable speeds combine demand of wide swath.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in detail: shown in the accompanying drawing 1, the utility model mainly includes: the spline housing 1 of an input power is fixed on the power shaft 3; Power shaft is by input gear 2 that is connected and the engagement that is connected in the transition gear 27 of transition axis 5; Transition axis is equipped with a change-speed gearing 4, on a variable-speed shaft, be fixed with the I retaining gear 25, II retaining gear 6, the III that correspond respectively to I, II, III retaining and keep off gear 24, and above-mentioned three gears respectively with change-speed gearing 4 corresponding realization speed changes; The III retaining gear 24 of variable-speed shaft and 8 engagements of steering cluth gear, the both sides of this steering cluth gear 8 all dispose steering cluth spline gear 9, big idle gear 12, little idle gear 13, and are meshed with driven wheel 14 on being connected in left and right sides axletree 15,20 by little idle gear 13.
Described change-speed gearing is provided with the manual control selector fork parts 26 that can make change-speed gearing 4 move left and right; And steering cluth spline gear 9 is provided with the clutch displacement fork 23 that is turned to by Driven by Hydraulic Cylinder, arrange two Multi-plate Wet Friction Clutch on steering clutch shaft, and they disposes the hydraulic jack that control turns to and brakes.
Two axletrees become same straight line about described, and each is arranged in parallel and is placed in the mould assembling formula casing by bearing respectively, and wherein driven wheel is placed in the casing by deep groove ball bearing.
Operation principle of the present utility model is: the power of hydraulic motor reaches power shaft 3 by spline housing 1; The power of power shaft reaches transition axis 5 by the engagement of input gear 2 and transition gear 27; The power of transition axis reaches variable-speed shaft 7 by the I on change-speed gearing 4 and the variable-speed shaft or II or III retaining gears engaged; The power of variable-speed shaft reaches steering cluth gear 8 by III retaining gear 24, and under the situation that does not have braking, the steering cluth gear directly reaches power driven wheel 14 by steering cluth spline gear 9, big idle gear 12, little idle gear 13; Driven wheel reaches power on the wheel of combine by left and right sides axletree 15,20, drives vehicle and travels.When needing gearshift, manually control selector fork parts 26 and rotate, make change-speed gearing 4 move left and right, realize gearshift.When needing to turn, rotate, make steering cluth spline gear 9 break away from steering cluth gear 8, thereby a side is cut off the transmission of power, under the driving of opposite side power, realize turning by Driven by Hydraulic Cylinder steering cluth displacement fork 23.When both sides power all is cut off, under the effect of Multi-plate Wet Friction Clutch 11, realize braking.
The utility model is that a kind of need not unpacking is the mechanical type three retaining crawler type infinitely variable speeds combine variable speed drives of detachable left and right sides axletree, and it adopts seven shaft type external gear pump transmissions, and left and right sides axletree becomes same straight line, and each is arranged in parallel.All gears adopt the external toothing spur gear, can be used for the crawler type infinitely variable speeds combine of hydraulic motor input.
