Description
Technical field
The utility model belongs to agricultural mechanical field, relates to a kind of tractor dynamic power output brake and clutch interlink controller.
Background technology
As everyone knows, tractor set 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 power output brake and power-transfer clutch have independent operating device separately, this independent operating device complex structure, handle trouble, and still be difficult to keep power output brake and clutch synchronization action, affect 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 namely the power take-off shaft spline docked with the facility splined hole because power output shaft head can not rotate fully.
The utility model content
The purpose of this utility model 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 efficiently tractor dynamic power output brake and clutch interlink controller.
The purpose of this utility model is to adopt following technical scheme to realize, tractor dynamic power output brake and clutch interlink controller comprise: power output clutch, power output brake, imput shaft, driving gear, power output box body; On the front end spline with imput shaft power output clutch is housed, the power output brake 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, the pressure oil duct communicates with the piston oil pocket of power output clutch, the piston oil pocket of power output brake respectively, between power output clutch and the power output brake power output box body is installed.
The brake hub of power output brake and imput shaft spline joint, the terminal pad of brake hub and braking dividing plate spline joint, brake strip and brake disc spline joint, brake disc places in the hole of power output box body, one 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 brake 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 power output box body.
The utility model adopts the advantage after the technique scheme to be: one, power output brake and power output clutch share a cover electrohydraulic control system, only need power switching output circuit of operation to get final product, and be simple in structure, easy to operate, low cost of manufacture; Its two, by pressure oil interlock steering maneuver output brake and the power output clutch of power switching output circuit 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, when even the power output brake is in braking mode, the power output shaft head spline 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 the utility model tractor dynamic power output brake and clutch interlink controller.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.The utility model comprises power output clutch D, power output brake E, imput shaft 1, driving gear 2, power output box body 3 etc., imput shaft 1 is supported on the top of power output box body 3 by two bearings, on the front end spline of imput shaft 1 power output clutch D is housed, power output brake E is housed on the spline of rear end, on the middle spline driving gear 2 is housed, 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 power output brake E respectively, and power output clutch D and power output brake E handle control by electric liquid.
Power output brake 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 places in the hole of power output box body 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 brake 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 power output box body 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, pushing 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, the rotation of driving power take-off shaft, namely power output clutch D is in engagement state; At this moment, because pressure oil also enters the piston oil pocket C of power output brake E simultaneously, promoting cylinder body 15 moves right, overcome the pressure of disk spring 16, make cylinder body 15 and braking dividing plate 10 produce the gap, brake hub 9 and braking dividing plate 10 relative brake strips 11 and brake disc 12 idle running, power output brake E is in off-state.
Disconnect 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 namely power output clutch D is in released state.At this moment, because the piston oil pocket C of power output brake 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 become one with brake disc 12 and implement braking, power take-off shaft is stopped operating synchronously.
The utility model is simple in structure, control comfort, and synchronous braking is effective, can be widely used in trac. farmland operation unit and use.
