Abstract
The purpose of this utility model is to provide that a kind of structure is simple, practical, user cost is low, assembling and cat infinitely variable transmission easy to maintenance.A kind of cat infinitely variable transmission of the present utility model, adds hydrostatic stepless speed changes devices (HST) structure owing to have employed power taking connecting plate, and the driving force of walking transmission is transmitted by solid shaft, and without clutch.Power output power through clutch, hollow shaft transmission.Walking drive path and Power output are independent separately, are independent of each other, at utmost meet every job requirements of cat.Have employed jack shaft and intermediate drive gear structure because travel unit divides again, make the component using existing self-propelled combine special gear box in a large number become possibility.After improving, greatly reduce gearbox manufacture cost and rate of fault, decrease maintenance expenses.
Description
Technical field
The utility model belongs to farm machinery, specifically a kind of cat infinitely variable transmission.
Background technique
Due to the destruction of wheeled tractor when paddy-field-working to plough pan, namely ecological agriculture cat arises at the historic moment, so far existing history more than 5 years.At present, China's cat infinitely variable transmission does not also have appropriate products, be mostly the transformation of the way of self-propelled combine special gear box to form, because cat machine infinitely variable transmission is large compared with self-propelled combine special gear box working load, it is unreliable that cat infinitely variable transmission uses, and fault is many.The improvement of this cat infinitely variable transmission, at home and abroad have not been reported at present.
Model utility content
The purpose of this utility model is to provide a kind of structure simpler, manufactures, user cost is low, assemble and keep in repair cat infinitely variable transmission more easily.
In order to solve the problems of the technologies described above, the utility model provides following technological scheme:
A kind of cat infinitely variable transmission, it is characterized in that it comprises power engine flywheel, power taking connecting plate, clutch, gearbox casing, top in gearbox casing is provided with solid transmission shaft and Hollow Transmission Shafts, and the middle part of gearbox casing is provided with jack shaft and pto＝power take-off, and gearbox casing is also provided with several driving gears and bearing.
Described a kind of cat infinitely variable transmission, it is characterized in that power taking connecting plate is arranged between power engine flywheel and clutch friction plate, power taking connecting plate uses clutch to lengthen fixing bolt and power engine flywheel is fixed together, be spline in the middle of power taking connecting plate, by spline joint solid transmission shaft, solid transmission shaft is bearing on power engine flywheel by bearing one end, and the other end is bearing in Hollow Transmission Shafts.
Described a kind of cat infinitely variable transmission, it is characterized in that described pto＝power take-off is connected with clutch, clutch is connected with Hollow Transmission Shafts, and Hollow Transmission Shafts is bearing on gearbox casing by two bearings.
Described a kind of cat infinitely variable transmission, is characterized in that described jack shaft is provided with intermediate drive gear.
A kind of cat infinitely variable transmission of the present utility model, owing to have employed hydrostatic stepless speed changes devices (HST), the output speed of HST is 0--± 3000 rev/min.It is 0 that its Joystick is placed on neutral position rotating speed.Therefore walking transmission device does not need clutch, the driving force of walking transmission without clutch, and is transmitted by solid shaft.Also significantly reduce clutch load.After improving, greatly reduce Gearbox Fault rate, decrease maintenance expenses.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure, 1-power engine flywheel; 2-solid transmission shaft; 3-power taking connecting plate; 4-clutch friction plate; 5-Hollow Transmission Shafts; 6-hydrostatic stepless speed changes devices (HST); 7-jack shaft; 8-intermediate drive gear; 9-gearbox casing; 10-pto＝power take-off; 11---urges brake device; Z1-Z12, Z15-Z17, Z1 '-Z8 ' is driving gear, Z13-steering gear; Z14-central driver gear.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
As shown in Figure 1, the utility model is that a kind of cat infinitely variable transmission adopts and the direct-connected Placement of power engine, Power output power is through clutch, hollow shaft 5 is delivered to Z1 '/Z5 ' or (Z2 ' → Z6 ') → Z7 '/Z3 ' → Z4 '/Z8 ' → pto＝power take-off 10, for pto＝power take-off provides two kinds of speed; In table 1 Power output drive path of the present utility model table.Walking transmission driving force by solid shaft be delivered to Z5/Z6 → hydrostatic stepless speed changes devices (HST) 6 → Z4/Z3 →, I shelves Z7/Z9 (II shelves Z2/Z1 or IIII shelves Z8/Z10) → Z10/Z11 → Z12/Z14 → Z13/Z15 → Z16/Z17 → live axle; In table 2 walking transmission of the present utility model drive path table.
Table 1: Power output drive path table of the present utility model
Table 2: walking transmission drive path table of the present utility model
The dental inlay for turning to is had between central driver gear Z14 and both sides steering gear Z13, by turning to shift fork (not shown in FIG.), can to be separated or in conjunction with dental inlay, namely cut off or connect the driving force from central driver gear, be rotated further and turn to shift fork, the outside mobile urges brake device 11 of steering gear, makes steering gear Z13 brake, the reduction gear that steering gear and reduction gear Z15 often engage is braked, by the Z16/Z17 gear transmission → live axle braking of normal engagement; Even if unit is braked; Unclamp and turn to declutch control lever, steering gear, under the pushing effect turning to spring, makes to turn to dental inlay to recombine, unit straight-line travelling.Left and rightly turn to shift fork by rotating, supporting facility just can realize left and right having turned to easily and flexibly.
In a word, improve after facility assembling and easy to maintenance; Reduce rate of fault, decrease maintenance expenses, improve the overall performance of gearbox.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., be all included within protection domain of the present utility model.
