Abstract:
An on-vehicle disc brake lathe system for resurfacing a brake disc of a vehicle brake assembly, the brake lathe system comprising:a lathe body with a driving motor; a cutting head operably attached to the lathe body; a drive shaft extending from the lathe body and operably connected to the driving motor so as to be rotated by the driving motor; a mechanical coupling connected to tie drive shaft and configured to provide an adjustable connection between the drive shaft and the vehicle brake assembly, the mechanical coupling including a first component connected to the drive shaft, a second component including structure for connection to the vehicle brake assembly, and a mechanical adjustment element between the first component and the second component, the mechanical coupling being configured to vary an axial alignment of the first component relative to the second component by moving the mechanical adjustment element; and an electronic control system connected to the mechanical coupling and operable to automatically adjust the adjustable connection provided by the mechanical coupling so as to improve alignment of the cutting head relative to an axis of rotation of the vehicle brake assembly as the drive shaft rotates.
