A drive shaft made from composite materials that comprises a hollow body and a flange that is integrally formed with the hollow body. The hollow body is adapted to rotating around an associated rotation axis and is made of a first composite material. The flange is made of a second composite material and arranged at an axial end of the hollow body. The flange comprises at least two separate plates that branch out from the hollow body at the axial end. The flange further comprises a mounting section that is configured to be mounted to an external component and comprises a plurality of holes that is adapted to accommodate coupling means.

A flexible coupling for coupling a first shaft and a second shaft includes a first body and a second body. The first body includes a first end to be fixed to the first shaft, a second end to be fixed to the second shaft and a first tooth, fixed to the radially inner face. The second body is secured to the first body, and has a radially outer face and a second tooth fixed to the radially outer face. The first tooth and the second tooth come into contact when a torque is applied to the first end of the first body so as to transmit the torque to the second end of the first body by the intermediary of the second body.

A heated throttle valve apparatus is disclosed herein, which includes a valve system with a valve driver configured to provide a rotational force to a valve assembly via a thermal isolating drive coupler configured to prevent the transfer of thermal energy from the valve assembly to the valve driver. The valve assembly includes a valve body and a valve closure member, a valve shaft with a valve shaft heater in a first heating zone and one or more body heaters in a second heating zone, permitting the user to control temperature in the heating zones independently. An electrical conductor strain relief is provided, configured to eliminate strain in the shaft heater electrical conductors when the valve closure member undergoes a change in angular orientation. The electrical conductor strain relief includes a curvilinear flexible member wound between a first connection area and a second connection area.

A coupling assembly arranged between an input shaft and a rotor shaft of a supercharger includes a first hub, a second hub, a first side coupling assembly, a second side coupling assembly, a central hub and a plurality of coupler pins. The first hub is mounted for concurrent rotation with the input shaft. The second hub is mounted for concurrent rotation with the rotor shaft. The first side coupling assembly has a first side coupling body and a first side elastomeric insert. The first side coupling body includes an inboard body portion having a first series of pockets and an outboard body portion having a second series of pockets. The first side elastomeric insert has a first and second plurality of lobes. The pockets of the first and second series of pockets are tangentially offset relative to each other and each receive respective first and second plurality of lobes therein.

The invention relates to a driveshaft assembly comprising an elongated front shaft (3), a retaining element (10) being engaged from a connection end (50) with the front shaft (3) in a co-rotating manner and a coupling device (20) secured to the front shaft (3) by means of the retaining element (10). The driveshaft further comprises a gear part (52) which is extending on the connection end (50) and the retaining element (10) is having a sleeve (17) fits to the gear part (52) in axially slidable manner.

An engine damper includes a drive disc having a plurality of studs circumferentially arranged to be received in a flex plate and a driven disc connected to the drive disc by a resilient member. The driven disc defines a plurality of circumferentially arranged first holes arranged in a first pattern. A hub is configured to non-rotatably connect to a shaft. The hub defines a plurality of second holes circumferentially arranged in a second pattern that corresponds to the first pattern. Connectors are disposed in the first and second holes to connect the hub to the driven disc.

A flexible coupling comprises a flexible torque disc (24) having a first plurality of fixing points (24a) whereby it can be mounted upon a first rotatable component (12), in use, and a second plurality of fixing points (24b) whereby it can be mounted upon a second rotatable component (14), in use, a support ring (26), and mounting means (34) whereby the flexible torque disc (24) is secured to the support ring (26), the mounting means (34) restricting deflection of the flexible torque disc (24) relative to the support ring (26).
