Description
Technical field
The invention belongs to agricultural mechanical field, relate to a kind of tractor dynamic power output brake and clutch linkage operating control.
Background technology
As everyone knows, the trac. unit often needs to engage or the detachment dynamic output clutch when farmland operation, so as the rotation of control tractor motive power output shaft with stop.When the power that cuts off power take-off shaft needed facility to quit work, because effect of inertia, facility can lag behind and quit work and produce the situation of mal operation.Thereby the dynamic output brake of part trac. design and installation makes and forces to stop the power take-off shaft rotation when cutting off power.The manipulation of tractor dynamic power output brake all is independently in the prior art; Be that the takeoff output brakes and clutches all has independent manipulation device separately; This independent manipulation apparatus structure is complicated; Handle trouble, and still be difficult to keep takeoff output brakes and clutches synchronization action, influence its operation effectiveness.In addition, after the tractor dynamic power output brake was implemented braking in the prior art, with the difficulty that is connected of facility, the key tooth can produce interference when promptly the takeoff output male splines docked with the facility splined hole because the takeoff output spindle nose can not rotate fully.
Summary of the invention
The object of the invention is exactly in order to overcome the deficiency in the above technology, to provide a kind of simple in structure, control comfort, and synchronous braking is effective, and unit connects tractor dynamic power output brake and clutch linkage operating control efficiently.
The objective of the invention is to adopt following technical scheme to realize that tractor dynamic power output brake and clutch linkage operating control comprise: power output clutch, takeoff output drg, imput shaft, driving gear, takeoff output casing; On the front end spline with imput shaft power output clutch is housed; The takeoff output drg is housed on the spline of rear end; On the middle spline driving gear is housed; Imput shaft is provided with the pressure oil duct vertically, and the pressure oil duct communicates with the piston oil pocket of power output clutch, the piston oil pocket of takeoff output drg respectively, between power output clutch and the takeoff output drg takeoff output casing is installed.
The braking hub of takeoff output drg is connected with the imput shaft spline; The terminal pad of braking hub is connected with braking dividing plate spline; Brake strip is connected with the brake disc spline, and brake disc places in the hole of takeoff output casing, and an end of fixed pin shaft inserts in the long otch of brake disc; Brake piston is positioned at cylinder body, and belleville spring will be braked dividing plate, brake strip is pressed between cylinder body and the braking hub.
Brake disc is provided with a long otch along its excircle, and an end of fixed pin shaft is positioned at this long otch, and the other end is fixed and clamped on the takeoff output casing.
The present invention adopts the advantage after the technique scheme to be: one of which, and the shared cover electrohydraulic control system of takeoff output drg and power output clutch only needs takeoff output contactor of operation to get final product, and is simple in structure, easy to operate, low cost of manufacture; Its two, by the pressure oil interlock steering maneuver output brake and the power output clutch of takeoff output contactor control, realize the synchronization action of two devices fully, improved the unit operation performance, reach operating needs; They are three years old; Because brake disc is designed with a long otch along its excircle; Allow fixed pin shaft restriction brake disc in long otch scope, freely to rotate; Therefore, even when the takeoff output drg is in braking mode, power take-off shaft headdress flower key also can freely rotate a tooth and conveniently dock with the splined hole of facility.
Description of drawings
Fig. 1 is the structural representation of tractor dynamic power output brake of the present invention and clutch linkage operating control.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is further described.The structure of tractor dynamic power output brake of the present invention and clutch linkage operating control; Comprise: power output clutch D, takeoff output drg E, imput shaft 1, driving gear 2, takeoff output casing 3 etc.; Imput shaft 1 is supported on the top of takeoff output casing 3 through two bearings; On the front end spline of imput shaft 1 power output clutch D is housed; Takeoff output drg E is housed on the spline of rear end, driving gear 2 is housed on the middle spline, the ring gear engagement on driving gear 2 and the power take-off shaft; Imput shaft 1 is provided with pressure oil duct A vertically, and communicates with the piston oil pocket B of power output clutch D, the piston oil pocket C of takeoff output drg E respectively, and power output clutch D and takeoff output drg E handle control by electric liquid.
Takeoff output drg E comprises A end, passive part, actuating element, and the braking hub 9 of A end is connected with imput shaft 1 through spline, and the terminal pad of braking hub 9 is connected with braking dividing plate 10 through spline; The brake strip 11 of passive part is connected with brake disc 12 through spline, and brake disc 12 places in the hole of takeoff output casing 3, the rotation of fixed pin shaft 13 restriction brake discs 12; The brake piston 14 of actuating element forms a seal oil chamber C with cylinder body 15, and belleville spring 16 will be braked dividing plate 10, brake strip 11 is pressed between cylinder body 15 and the braking hub 9.
It is 140 ° otch that brake disc 12 is provided with arc length along its excircle; The angle that brake disc 12 rotated when the spline that this incision length is equivalent to power take-off shaft rotated a tooth; It is 140 ° otch that one end of fixed pin shaft 13 is positioned at arc length, and the other end is fixed and clamped on takeoff output casing 3.
Power output clutch D is the conventional structure of multi-disc wet type, repeats no more at this.
Mode of operation: connect power take-off valve; Pressure oil gets into the piston oil pocket B of power output clutch D through pressure oil duct A; Promotion piston 8 is moved to the left and compresses dividing plate 5 and friction lining 6; Power passes to imput shaft 1, driving gear 2 by active hub 4, dividing plate 5, friction lining 6, passive hub 7, drives the power take-off shaft rotation, and promptly power output clutch D is in engagement state; At this moment; Because pressure oil also gets into the piston oil pocket C of takeoff output drg E simultaneously; Promote cylinder body 15 and move right, overcome the pressure of disk spring 16, make cylinder body 15 and braking dividing plate 10 generation gaps; Braking hub 9 and braking dividing plate 10 relative brake strips 11 and brake disc 12 idle running, takeoff output drg E is in off-state.
Break off power take-off valve, pressure oil cuts off, and produces the gap between the dividing plate 5 of power output clutch D and the friction lining 6, power cut, and piston 8 is returning quickly under helical spring effect, and promptly power output clutch D is in released state.At this moment; Because the piston oil pocket C of takeoff output drg E does not have pressure oil yet; Disk spring 16 promotes cylinder body 15 left; Compress braking dividing plate 10 and brake strip 11, make braking hub 9, braking dividing plate 10, brake strip 11 become one with brake disc 12 and implement braking, power take-off shaft is stopped operating synchronously.
The present invention is simple in structure, control comfort, and synchronous braking is effective, can use adaptable across trac. farmland operation unit.
