Patent ID: 7712358

Claim:
Apparatus for testing a component of a drive train of a vehicle, the apparatus comprising an output drive line for connection to an output of the component, an input drive line for connection to an input of the component, the input and output drive lines being operable to test the component with a predetermined combinations of drive speed and torque, wherein each of the input and output drive lines has a coupling for engaging with a corresponding coupling of the component and each of the drive lines is mounted for movement into and out of engagement with the component, the coupling of one of the input and output drive lines having a radially facing engagement surface and an axially facing reference surface, the engagement surface of the coupling of the drive line being for engaging with a corresponding radially facing engagement surface of the component the coupling of the component having an axially facing reference surface, and a controller arranged to move the said one of the drive lines towards the component so that the engagement surfaces of the coupling and component engage, with their reference surfaces spaced by a predetermined amount, and to initiate testing of the component whilst maintaining the said engagement and the said predetermined amount of spacing.
