    Abstract: A brake-clutch assembly applicable as a safety element in machines having a start-stop movement, such as presses, shears and the like, has a hub which is to be mounted on a machine shaft and a brake-side cover having a cylindrical part defining a cylindrical cavity for admitting compressed air. A friction disc is mounted on the cylindrical part. The hub also carries a central piston-plate which supports two rings having frictional linings on both the brake side and the clutch side. The inner diameter of the cylindrical part is considerably larger than the inner diameter of one of the locking rings, thereby allowing a maximum power to be achieved because the cylindrical cavity defining a pressure chamber can be extended to attain a diameter close to that of the friction disc. This is achieved by removing the material in an area of the central piston-plate.

When the signal changes from OFF to ON, which means that the brake pedal has been trodden, the antilock control function is disabled so that the pressure generated in the master cylinder will be directly applied to the wheel cylinders. This state continues until the antilock device detects a locking tendency of any wheel. In addition to the brake lamp switch signals, signals representative of the ON and OFF positions of the accelerator pedal may be supplied to the antilock control device so that the antilock control function will be disabled when either the accelerator pedal position signal changes from OFF to ON or the brake pedal position signal changes from ON to OFF.

  • Patent number: 4422600
    Abstract: This invention relates to a fishing reel which has free spooling, variable drag, and lock up action controlled by an exterior lever. The lever is cammed to a draw rod, which, in turn, through a floating contact, pins journalled through the reel housing, and a thrust bearing, urges a brake disk against a brake lining fixed to the spool. The floating contact is adjustable for presetting the maximum drag and provides smooth operation even under conditions of a warped brake disk or uneven brake lining. And use of approximately a dozen pressure pins, depending on reel size, avoids pressure warpage of the thrust bearing race and consequent binding during maximum drag operation. The brake disk, floating contact, journalled pins, and thrust bearing are located in a housing opposite that containing the lever, winding handle, and a second thrust bearing for the spool and thereby permit easy access for repair.

    Abstract: Disclosed is a torque transmitting and blocking device which includes a cylindrical drum, a pair of arcuate shoes positioned within the drum, and a spanner bar or ring extending between the shoes to one side of the axis of the drum. On the other side of the drum axis the shoes are displaceable toward each other, and may conveniently be lightly biased apart. The shoes have surfaces, which may include holes, lateral or transverse projections, or the ends of the shoes, through which rotative forces may be transmitted from sources external of the drum and through which the shoes may retransmit such forces. Application of a rotational force through such a surface into a shoe in a direction tending to displace the shoes toward each other results in rotation of the shoes and bar within the drum, and consequent transmission of torque, if desired, out of the drum through another shoe surface.

    Abstract: A film wrapping dispenser having a fluid pressure actuated, controlled drag shaft is disclosed. It comprises a cylindrical, hollow tube wall which is formed of an extensible material which envelopes a fluid pressure-tight cavity. The tube wall rotatably engages an inner cylindrical bearing surface of a relatively rotating member. A controllable fluid pressure source is connected to the tube for selectively applying fluid pressure within the cavity to radially expand the tube wall. This enables the selective frictional engagement of the tube wall with the inner cylindrical surface of the member. The pressure source may be a bellows shaped as a handle which is integrally formed with the tube wall on one end of the cylinder. The tube and bellows may be precharged with a fluid pressure of sufficient magnitude to impart a relatively low degree of frictional engagement when the bellows is relaxed and to provide a relatively high degree of frictional engagement when the bellows is compressed.

  • Patent number: 4310080
    Abstract: A ratarder for a power transmission shaft comprises a liquid immersed coupling between the shaft and a drag member, the drag member being normally entrained to rotate with the shaft by viscous drag in the coupling. A dry brake mechanism, having a frictional drag greater than that of the coupling, is provided to restrain the drag member for relative movement to take place in the coupling. In the embodiments shown, the coupling comprises a friction disc pack alternately connected to the shaft and the drag member, the brake mechanism firstly restraining the drag member and subsequently shifting it axially to engage the friction disc pack.The coupling is suitable for use in heavy motor vehicle transmission systems.

  • Patent number: 4269291
    Abstract: The driving, braking and freewheeling device for tricycles has a simplified structure including a central circular disc driven by a pedal-operated shaft. Cams, symmetrically positioned around the periphery of the central disc, oppose brake shoes which form a segmented ring within the hub of the vehicle's driven wheel. The inner surfaces of the brake shoes are contoured to act as cam followers. Application of torque to the drive shaft in a first direction forces the brake shoes outwardly until engagement is made with an inner surface of the wheel causing the wheel to rotate. When no torque is applied to the drive shaft there is no cam action to force the brake shoes outwardly against the wheel thus permitting the wheel to rotate freely. When the drive shaft is torqued in the opposite direction, the cams force the brake shoes to engage the inner surface in opposition to the rotation of the driven wheel and effect a braking action.

  • Patent number: 4248331
    Abstract: A combined clutch and brake control is provided for a lawn and garden tractor of the type including a traction drive transmission, formed in part by an infinitely variable pulley, and including a traction drive brake. The control includes a clutch brake pedal adapted for connection to the infinitely variable pulley and to the brake and operable when depressed to act on the pulley to sequentially reduce the transmission speed to zero and then apply the brake; and includes a brake pedal coupled to the brake and operable to apply the brake to prevent rolling during hillside operation when the clutch-brake pedal is being depressed through a neutral range or zone located between clutching or speed reducing and braking ranges. An adjustable spring is connected to the brake for limiting the amount of force applied thereto via operation of the clutch-brake and brake pedals.

  • Patent number: 4226312
    Abstract: The disclosure provides for a number of improvements in a brake-clutch mechanism wherein a drum is carried on the drive member for driving engagement by clutch shoes carried by the driven member. The clutch shoes are normally biased into driving engagement with the drum and a brake band is utilized to move the clutch shoes out of engagement with the drum and to stop rotation of the driven member without interrupting the rotation of the drive member. The improvements relate to a higher torque capability for the mechanism, the exclusion of foreign matter from the mechanism, the mounting for the brake band, the use of the brake band to aid in keeping the braking surfaces clean, and provision for cut-off of the power source in the event the brake band should fail. The disclosure further contemplates a novel arrangement for driving and controlling the chain sprocket of a chain saw.

  • Patent number: 4141439
    Abstract: A combined clutch and brake mechanism for use in such applications as power lawnmowers. During actuation of a manual control the brake is released and power is transmitted from the engine to the blade carrier. If the manual control is released, power transmission is disabled and braking is initiated, the braking being maximized by the very motion of the member being braked. The invention is also shown in a form adaptable for use in general power transmission applications.
