Abstract
An electric hydraulic control power output clutch comprises a driving hub, a driven hub, a catch, driving friction plates, driven friction plates, a spiral return spring, a pressure plate, a piston, a combined sealing ring and a piston cylinder. The driving hub is connected with a shaft A of the power output clutch via a spline, the driven hub is connected with a shaft B of a power output transmission case I via a spline, 6-9 pairs of driving friction plates and driven friction plates are mounted between the driving hub and the driven hub, the driven hub is provided with the catch, the spiral return spring is mounted between the driven hub and the pressure plate, the combined sealing ring is installed between the piston and the piston cylinder, and the driving friction plates and the driven friction plates are all wet type friction plates. The power output clutch adopts the wet friction plates, and is smaller in volume compared with a single-chip dry type double-action clutch transmitting equal power. Devices needing continuous power, such as a hydraulic pump and the like, can be conveniently disposed at the rears of the shaft of the transmission case and the shaft of the power output clutch by the aid of the power output clutch. In addition, the power output clutch can realize electric hydraulic control via an electromagnetic valve, and combination and separation of the clutch can be conveniently controlled via a button switch.
Description
Technical field
The utility model belongs to the tractor field, relates to a kind of clutch, relates in particular to a kind of used with tractor electrichydraulic control power output clutch.
Background technique
At present, on the large power wheel tractor that China produces, the power output clutch that is disposed mostly is the double-action clutch that is made of one with main clutch, and this double-action clutch is installed between motor and the gearbox.When the detachment dynamic output clutch, the power of motor just cuts off with the power output clutch axle, can't arrange in gearbox that oil hydraulic pump for example etc. needs the device of continuous power resources again.The main clutch volume of large power wheel tractor is bigger, if power output clutch is made of one with it, will make its structure complicated more, cause the clutch reliability to reduce, and big-power tractor often needs a plurality of oil hydraulic pumps to satisfy the needs of its difference in functionality, if all be contained on the motor then difficulty is bigger.Therefore, at tractor rear portion configuration power output clutch, can make tractor dynamic power output clutch axle under the situation that power does not cut off, cut off the power of power output transmission case, convenient oil hydraulic pump and other arranged in gearbox needs the device of continuous power resources, the power output clutch that band brake is also arranged in the prior art is installed butterfly spring between its active hub and the platen, and the spring returning place force is bigger, under same system pressure, the coefficient of torque reserve of clutch is lower.
The model utility content
The purpose of this utility model be to provide a kind of rational in infrastructure, use used with tractor electrichydraulic control power output clutch reliable, easy operation.
The technical solution of the utility model is: a kind of electrichydraulic control power output clutch mainly comprises initiatively hub, driven hub, catch, active friction plate, from movable friction plate, helical return spring, platen, piston, combined seal ring, piston cylinder; It is characterized in that: initiatively hub is connected by spline with power output clutch axle A; B of driven hub and power output transmission case is connected by spline; Initiatively be equipped with between hub and the driven hub 6～9 pairs of active friction plates with from movable friction plate; Catch is housed on the driven hub; Between driven hub and the platen helical return spring is housed; Between piston and the piston cylinder combined seal ring is housed; Active friction plate be the wet friction sheet from movable friction plate.
The utility model can reach following beneficial effect after adopting technique scheme: because the power output clutch device adopts multi-disc wet friction sheet, transmission is little with the conventional one-piece dry type double-action clutch volume of constant power power, the device of the continuous power of needs such as oil hydraulic pump can be configured in easily the rear portion of transmission case power output clutch axle; Power output clutch can be realized electrichydraulic control by solenoid valve, be convenient to by the push-button switch solenoidoperated cluthes combination with separate.The power output clutch piston is by the helical spring return, because return spring power is less, can effectively increase the torque reserve of clutch.
Description of drawings
Accompanying drawing is the main TV structure sectional view of the utility model electrichydraulic control power output clutch.
Embodiment
The utility model will be further described below in conjunction with accompanying drawing.As shown in drawings the electrichydraulic control power output clutch mainly comprise initiatively hub 1, driven hub 2, catch 3, active friction plate 4, from movable friction plate 5, helical return spring 6, platen 7, piston 8, combined seal ring 9, piston cylinder 10; Initiatively hub 1 is connected by spline with power output clutch axle A; B of driven hub 2 and power output transmission case is connected by spline; Initiatively between hub 1 and the driven hub 2 6～9 pairs of active friction plates 4 are housed and from movable friction plate 5; Catch 3 is housed on the driven hub 2, guarantees active friction plate 4 and can compress reliably from movable friction plate 5; Between driven hub 2 and the platen 7 helical return spring 6 is housed; Because the returning place force of helical return spring 6 is less, under same system pressure, the torque reserve of clutch is bigger, and OE type combined seal ring 9 is housed between piston 8 and the piston cylinder 10; This seal ring starting friction resistance is less, can effectively reduce the return resistance of piston; Active friction plate 4 be the wet friction sheet from movable friction plate 5, the wet friction sheet, high temperature resistant, working life is than the dry type length of a film that rubs.
Electrichydraulic control power output clutch working principle: when clutch in conjunction with the time, the piston cavity that the inside oil duct of one road hydraulic oil by a B of power output transmission case enters clutch overcomes the returning place force of helical return spring 6, promote piston 8 and platen 7 will be many to active friction plate 4 with compress the combination of realization clutch from movable friction plate 5.Simultaneously, the inside oil duct of another road hydraulic oil by a B of power output transmission case is to the active friction plate 4 of clutch, be lubricated and dispel the heat from movable friction plate 5; When clutch separation, the hydraulic oil in the piston cavity is by the control oil channel off-load, and at this moment helical return spring 6 pushes back piston 8, makes clutch separation.The combination that the operator on the tractor can realize clutch by the push-button switch control electromagnetic valve with separate, alleviated driver's labor intensity greatly, made things convenient for operation, improved working efficiency.
