  • Patent number: 11692598
    Abstract: A one-way clutch, including: a case; a drive plate enclosed by the case and defining openings; a first plate non-rotatably connected to the case and defining a first opening; a rotatable actuator plate; a strut including a central portion, an engagement portion, and a control portion; and a spring. In a locked mode: the spring pivots the engagement portion into an opening of the drive plate, a rotation of the drive plate in a first direction is enabled, and a rotation of the drive plate in a second direction is blocked. To transition from the locked mode to a free-wheel mode, in which the rotation of the drive plate in the second direction is enabled, the actuator plate is rotated by an actuator to contact the control portion and pivot the strut to displace the engagement portion out of the opening of the drive plate.

  • Patent number: 6361460
    Abstract: The present invention relates to a device for driving a sprocket of a bicycle, which enables a rider to easily rotate both pedals even with little force when both cranks of the pedal are vertically positioned. According to the present invention, when a crank (11) gets to be vertically positioned by rotating the pedals (11a), a guide pin (21) projected from a rotating plate (20) draws a tensile spring (41) from the guide groove (31) and thereby the rotating plate (20) gets to be elastically rotated so the crank (11) can go off the vertical position rapidly. Accordingly, the rider can easily rotate the pedals, and at the same time, the force of restitution of the drawn tension spring (41) can help the sprocket (10) be rotated. Consequently, the accumulated force of the tensile spring (41) accelerates the rotation of the sprocket (10) to enable the crank (11) to go off the vertical position effectively, which in turn enables the rider to drive the bicycle with ease.

  • Patent number: 5944156
    Abstract: A power transmission mechanism which is adapted to completely interrupt power transmission when a torque exceeds a predetermined value, and which has a simple configuration and is manufactured at low cost, and which is bidirectionally rotatable. When a torque, whose magnitude is not more than the predetermined value, is transmitted from a pulley (1) to a shaft (4), each of three elastic members is accommodated in such a manner as to extend over both of a holding portion (3) of the pulley and a holding part (6) of a hub (5). When an excessive torque, whose magnitude exceeds the predetermined value, is applied to the pulley, deformation of each of the elastic members is gradually enhanced by a compressive force applied from the pulley in a radial direction, so that each of the elastic members moves in the radial direction. Then, each of the elastic members further advances and is detached from a corresponding one of the holding portion of the pulley.

  • Patent number: 5862706
    Abstract: A shaft deflection controller includes an input driveshaft adapted for inputting power from an engine. The input driveshaft includes an axis of rotation and a spur pinion at an end of the input driveshaft. The axis of rotation of the input driveshaft changes, relative to a frame, with deflections of the input driveshaft. Two face gears are adapted for meshing with the spur pinion of the input driveshaft. A flexible shaft stabilizing mount includes an inner sleeve portion and a mounting flange. The inner sleeve portion includes a base portion connecting the inner sleeve portion to the mounting flange and a plurality of cage spring members. The mounting flange is connected to and concentric with the inner sleeve portion. The flexible shaft stabilizing mount controls the deflection of the input driveshaft by applying forces onto the input driveshaft, which tend to resist changes in the alignment of the axis of rotation of the input driveshaft. The flexible shaft stabilizing mount is connected to a rigid frame.

  • Patent number: 5810668
    Abstract: A fuel pump drive gear assembly is provided which includes torsional absorption elements positioned between a drive gear and a fuel pump hub. The drive gear includes a plurality of apertures for receiving a plurality of projections formed on the fuel pump hub. The torsional absorption elements are positioned in the apertures between the projections and the drive gear so as to frictionally engage a surface of both the projection and the drive gear, thus creating a mechanical driving connection between the rotating drive gear and the fuel pump hub. The torsional absorption elements have adequate stiffness to provide the necessary torque to drive the fuel pump, while retaining sufficient flexibility to permit relative rotational movement between the driving gear and the fuel pump hub for absorbing the vibratory loads imposed upon the gear assembly by the fuel pump without compromising the timing between the fuel pump and engine.

    Abstract: An armature assembly for an electromagnetic coupling includes an armature plate made of a material having low magnetic reluctance and also includes an output hub having angularly spaced and radially extending mounting arms for supporting the armature plate. The armature plate is connected to the mounting arms by angularly spaced leaf springs which couple the armature plate and the output hub for rotation in unison while allowing the armature plate to move axially relative to the mounting arms when the coupling is engaged and disengaged. The leaf springs are made of a material having high magnetic reluctance and are formed with tabs or fingers which are sandwiched between the armature plate and the mounting arms to create a flux barrier for magnetically isolating the armature plate from the mounting arms and the output hub.

  • Patent number: 4943261
    Abstract: A flexible drive coupling for transmitting rotational forces between respective flanges of a driving shaft and a driven shaft. The flexible drive coupling has, in a substantially planar circular configuration, a number of wedges. The wedges have respective end faces facing the adjacent wedges and connected thereto by flexible elements. Alternate wedges attach respectively to the flanges of the driving and driven shafts. The flexible elements consist of a link between two end plates. The mating faces of the link and the end plates are curved so that they co-operate one with the other. An elastomeric filler occupies the space between the curved surfaces of the end plates and the links permitting each end plate to pivot with respect to the link by deforming the elastomeric filler. The end faces of the wedges and, the corresponding faces of the end plates of the flexible elements which face them, have co-operating tabs and recesses to prevent relative radial and axial movement.
