  • Patent number: 7806012
    Abstract: A drive unit includes a gear set driving a drive pulley that in turn drives a flexible drive member which is attached to a driven member by an attachment assembly that travels in a channel. The attachment assembly is attached to the flexible drive member by a coupler that has teeth that extend through respective windows of the flexible drive member. The coupler is disposed between side walls of a yoke and attached to a bridge wall of the yoke. An outer shoe engages each side wall of the yoke. The attachment assembly includes an optional spring to tension the flexible drive member and the shoes have optional flexible tapered fingers to stabilize the drive pulley. The flexible drive member and the spring are trapped between the coupler and the bridge wall of the yoke.

  • Patent number: 7785220
    Abstract: An automotive vehicle has a power operated lift-gate that is opened and closed by two drive units. The typical drive unit has a guide channel, an attachment assembly that is disposed in the guide channel, a flexible drive member that is attached to the attachment assembly and formed in a loop for moving the attachment assembly in the guide channel. The flexible drive member is trained solely around two pulleys at the respective opposite ends of the guide channel to form the flexible drive member in a narrow loop. One of the pulleys is an idler pulley that is part of an adjustable pulley assembly and the other pulley is driven by a power unit that is attached to the guide channel. The adjustable pulley assembly adjusts the distance between the pulleys to take up slack in the flexible drive member.

  • Patent number: 7297082
    Abstract: A flexible drive member attachment is connected to a flexible drive member by a yoke having side walls connected by a bridge wall that has a stud connecting the attachment to a driven member. A coupler is disposed between the side walls and attached to the bridge wall. The coupler has teeth that extend through respective windows of the flexible drive member. An outer shoe engages each side wall of the yoke. Each outer shoe has a forward flange engaging the bridge wall and a rearward flange that extends through a rearward slot of the associated side wall. Each rearward flange has fingers that extend behind the flexible drive member and through spaces between adjacent teeth of the coupler and into sockets of the other shoe. The flexible drive member may be a drive chain or a drive belt having spaced windows.

  • Publication number: 20020104732
    Abstract: An electromagnetic clutch has a spool that houses an internal coil winding and that has a drive member attached to it. A molded plastic carrier cap is fitted onto an axial end of spool. Carrier cap has two thin, axially spaced slip rings that are secured to a peripheral wall of the carrier cap. The two slip rings are connected to input and output ends respectively of the coil winding. Coil winding is energized from a direct current source by stationery brush assemblies that are radially oriented and circumferentially spaced from each other. Each brush assembly includes a brush contact that is spring biased into contact with one of the slip rings. A plate rotor that has a drive member attached to it is next to the opposite axial end of the spool.
