Description
Technical field
The invention belongs to agricultural mechanical field, relate to a kind of tractor dynamic power output brake and clutch interlink controller.
Background technology
As everyone knows, tractor set, when farmland operation, often needs to engage or detachment dynamic output clutch, to control rotation and the stopping of tractor motive power output shaft.When cutting off the power of power take-off shaft and needing facility to quit work, due to effect of inertia, facility can delayed quitting work and produce the situation of mal operation.Thus, the dynamic output brake of part trac. design and installation, makes to force during cut-out power to stop power take-off shaft rotating.In prior art, the manipulation of tractor dynamic power output brake is all independently, namely Power output brakes and clutches has respective independent operating device, this independent operating device complex structure, handle trouble, and be still difficult to keep Power output brakes and clutches synchronization action, affect its operation effectiveness.In addition, after in prior art, tractor dynamic power output brake implements braking, because power output shaft head can not rotate completely with the connection difficulty of facility, when namely power take-off shaft spline docks with facility splined hole, key tooth can produce interference.
Summary of the invention
Object of the present invention is exactly the deficiency in order to overcome in above technology, and provide a kind of structure simple, control comfort, synchronous braking is effective, and unit connects tractor dynamic power output brake and clutch interlink controller efficiently.
The object of the invention is to adopt following technical scheme to realize, tractor dynamic power output brake and clutch interlink controller, comprising: power output clutch, Power output drg, imput shaft, driving gear, Power output casing; By on the front end spline of imput shaft, power output clutch is housed, Power output drg rear end spline is equipped with, middle spline is equipped with driving gear, imput shaft is provided with pressure oil duct vertically, pressure oil duct communicates with the piston oil pocket of power output clutch, the piston oil pocket of Power output drg respectively, is provided with Power output casing between power output clutch and Power output drg.
The brake hub of Power output drg and imput shaft spline joint, terminal pad and the braking dividing plate spline joint of brake hub, brake strip and brake disc spline joint, brake disc is placed in the hole of Power output casing, one end of fixed pin shaft is inserted in the long otch of brake disc, brake piston is positioned at cylinder body, and braking dividing plate, brake strip are pressed between cylinder body and brake hub by belleville spring.
Brake disc is provided with a long otch along its excircle, and one end of fixed pin shaft is positioned at this long otch, and the other end is fixed and clamped on Power output casing.
Advantage after the present invention adopts technique scheme is: one, and Power output drg and power output clutch share a set of electrohydraulic control system, only needs operation Power output contactor, and structure is simple, easy to operate, low cost of manufacture; Its two, the pressure oil that controlled by Power output contactor interlock steering maneuver output brake and power output clutch, realize the synchronization action of two devices completely, improve unit operation performance, reach operating needs; They are three years old, because brake disc is designed with a long otch along its excircle, fixed pin shaft restriction brake disc is allowed freely to rotate in long cut and hang, therefore, even if when Power output drg is in braking mode, power output shaft head spline also freely can rotate a tooth and conveniently dock with the splined hole of facility.
Accompanying drawing explanation
Fig. 1 is the structural representation of tractor dynamic power output brake of the present invention and clutch interlink controller.
Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.The structure of tractor dynamic power output brake of the present invention and clutch interlink controller, comprise: power output clutch D, Power output drg E, imput shaft 1, driving gear 2, Power output casing 3 etc., imput shaft 1 is supported on the top of Power output casing 3 by two bearings, the front end spline of imput shaft 1 is equipped with power output clutch D, Power output drg E rear end spline is equipped with, middle spline is equipped with driving gear 2, and driving gear 2 engages with the ring gear on 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 Power output drg E respectively, and power output clutch D and Power output drg E is by electric liquid maneuvering and control.
Power output drg E comprises A end, passive part, actuating element, and the brake hub 9 of A end is connected with imput shaft 1 by spline, and the terminal pad of brake hub 9 is connected with braking dividing plate 10 by spline; The brake strip 11 of passive part is connected with brake disc 12 by spline, and brake disc 12 is placed in the hole of Power output casing 3, and fixed pin shaft 13 limits the rotation of brake disc 12; Brake piston 14 and the cylinder body 15 of actuating element form a seal oil chamber C, and braking dividing plate 10, brake strip 11 are pressed between cylinder body 15 and brake hub 9 by belleville spring 16.
Brake disc 12 is provided with the otch of the corresponding arc length of 140 ° of central angles along its excircle, this incision length corresponds to the angle that when spline of power take-off shaft rotates a tooth, brake disc 12 rotates, one end of fixed pin shaft 13 is positioned at the otch that arc length is 140 °, and the other end is fixed and clamped on Power output casing 3.
Power output clutch D is the conventional structure of multi-sheet wet-type, does not repeat them here.
Mode of operation: connect power take-off valve, pressure oil enters the piston oil pocket B of power output clutch D by pressure oil duct A, promote piston 8 and be moved to the left compression 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, driving power take-off shaft rotates, and namely power output clutch D is in engagement state; Now, because pressure oil also enters the piston oil pocket C of Power output drg E simultaneously, promote cylinder body 15 to move right, overcome the pressure of disk spring 16, cylinder body 15 is made to produce gap with braking dividing plate 10, brake hub 9 dallies with brake disc 12 with braking dividing plate 10 relative brake friction lining 11, and Power output drg E is in off-state.
Disconnect power take-off valve, pressure oil cuts off, and produce gap, power cut between the dividing plate 5 of power output clutch D and friction lining 6, piston 8 is returning quickly under helical spring effect, and namely power output clutch D is in released state.Now, because the piston oil pocket C of Power 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 brake hub 9, braking dividing plate 10, brake strip 11 be integrated with brake disc 12 one-tenth and implement to brake, power take-off shaft is synchronously stopped operating.
Structure of the present invention is simple, control comfort, and synchronous braking is effective, can be widely used in trac. farmland operation unit and use.
