Description
Technical field
The present invention relates to clutch, is a kind of liquid damping static pressure type clutch.
Background technique
Generally between active machine and driven machine, often be provided with clutch, so that operate driven machine easily, for example, existing automobile all is provided with clutch between motor and speed changer, when wanting the conversion car speed, speed changer is broken away from and the contacting of motor, could operate shifting of transmission.Existing clutch generally has engagement sleeve, friction clutch, hydraulic couplers and torque converter etc., and wherein: engagement sleeve only is applicable to rotating speed 100-150 rev/min Synchronous Transmission.Though friction clutch is applicable at a high speed, skid and scaling loss easily, and structure is big, control moment is big automatically.Efficient under low speed such as hydraulic couplers and torque converter is extremely low.
Summary of the invention
The purpose of this invention is to provide a kind of Flooding clutch, utilize the incompressibility of the flow resistance of liquid and liquid realize machine initiatively and by between the motivation from, close, and make the moment of its transmission and rotating speed can implement any adjustment.
Realize the present invention of above-mentioned purpose, include a cylinder body that can be connected mutually and a rotating shaft that can be connected mutually with the main shaft of driven machine with the rolling disc of active machine, its center of cylinder body among the present invention is a hollow cylindrical, the inner chamber of cylinder body makes cylinder body have a cylindrical outer cylinder body and a cylindrical inner cylinder body in the form of a ring; In inner chamber of cylinder block, be provided with two pistons, make inner chamber of cylinder block constitute three hydraulic chambers that can link up; Two pistons are structure ringwise all, be provided with at least two centrifugal choke apparatus on the piston body of each annular piston in uniform way, extend at least two wrist pins on the inner circumference of each annular piston in uniform way, this wrist pin is embedded in the waveform guide groove of rotating shaft axle after passing the casing wall of inner cylinder body; Corresponding with annular piston, be provided with two circle waveform guide grooves on the circumferential rim face of rotating shaft symmetrically.The present invention also is provided with movable flow cover between the root of wrist pin and cylinder body bottom surface, have the assignment hole that can be connected with oil circuit on the cylinder body on the sidewall of this flow cover.
Centrifugal choke apparatus in the said structure of the present invention includes one centrifugal and a centrifugal damping piston, presses by two return springs for centrifugal and puts on piston body, and centrifugal damping piston is sat with a return spring and is pressed on centrifugal, and with a pressing plate solid pressure.
Its working method of the present invention is as mentioned above, is example with automobile with this Flooding clutch: 1, and " combination " of clutch.When opening the throttle booster engine, because of the cylinder body of this clutch and the flywheel of motor are connected mutually, then clutch cylinder body and flywheel rotate synchronously, after the rotating speed of motor is higher than the speed changer rotating speed, cylinder body drive annular piston rotates synchronously within the cylinder body, when reaching the setting rotating speed, be located at centrifugal elastic force that under the work of centrifugal force, overcomes return spring on the piston body to outer displacement, gradually the oil duct on the piston body is closed, at this moment, three hydraulic chambers in the cylinder body are disconnected mutually, liquid stream is static, the second ring piston stops to do axial runout under this static pressure effect, and then wrist pin drives the rotating shaft rotation that is connected mutually with the main shaft of speed changer, realizes " combination " of motor and speed changer at this moment.2, " separation " that clutch is in operation.When unclamping throttle and make engine retard and be lower than the speed changer rotating speed, be that the cylinder body rotating speed lags in the rotating shaft rotating speed, the annular piston rotation that also lags simultaneously, then wrist pin promptly drives the flow cover along the inner cylinder body rotation that lags, when the assignment hole on the sidewall of flow cover when oil circuit on the cylinder body communicates, three hydraulic chambers in the cylinder body form paths, indoor oil pressure reduction, annular piston then recovers to do free to-and-fro motion, promptly realizes " separation " of motor and speed changer this moment.3, " separation " of clutch when the rotating speed of motor is lower than the setting rotating speed.When the rotating speed of motor is lower than setting rotating speed (operation or bursty state), centrifugal centrifugal force is less than the spring-back force of two return springs, at this moment, under the effect of spring-back force centrifugal the withdrawal and the oil duct on the piston body is opened, three hydraulic chambers in the cylinder body are connected, and clutch is promptly realized " low speed separation ".
Advantage of the present invention is that the present invention has two pistons of structure ringwise, can transfer larger torque.Of the present invention from, close and need not other parts, simple in structure, compact, it is minimum to wear and tear, the life-span is long, and is easy to operate, is particularly suitable for high-power power machine and uses.
