Apparatus and method for automatically compensating for lateral runout
First Claim
1. An on-car 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;
at least one cutting head operably attached to the lathe body;
an input adaptor configured to be attached to the vehicle brake assembly;
a rotatable drive shaft;
an alignment mechanism including a sensor, the alignment mechanism operable to generate a measurement signal indicative of an orientation of a lathe axis of rotation with respect to a rotor axis of rotation and to adjust the orientation of the lathe axis of rotation with respect to the rotor axis of rotation; and
a microprocessor coupled to the alignment mechanism to electronically generate at least one control signal in response to the measurement signal, the at least one control signal used by the alignment mechanism to improve the alignment of the lathe axis of rotation with respect to the rotor axis of rotation.

Abstract
An on-car disc brake lathe system for resurfacing a brake disc of a vehicle brake assembly includes a lathe body with a driving motor, a cutting head operably attached to the lathe body, and a drive shaft. The system also includes an alignment system having an electronic controller, input and output adaptors configured to rotate with the drive shaft, one or more adjustment discs, and an adjustment mechanism. The adjustment disc is positioned between the input adaptor and the output adaptor, and an axial alignment of the input adaptor relative to the output adaptor may be varied based on a rotational orientation of the adjustment disc. The adjustment mechanism is configured to change the rotational orientation of the adjustment disc in response to commands from the electronic controller.

6. A method of resurfacing a brake disc of a vehicle brake assembly, the method comprising:
-
providing an on-vehicle brake lathe system having a lathe body with a driving motor, at least one cutting head operably attached to the lathe body, an input adaptor, and a rotatable drive shaft; attaching the input adaptor of the on-vehicle brake lathe system to the vehicle brake assembly; using an alignment mechanism including a sensor, the alignment mechanism operable to align the lathe body of the brake lathe system, to generate a measurement signal indicative of an orientation of a lathe axis of rotation with respect to a rotor axis of rotation; using a microprocessor coupled to the alignment mechanism to electronically generate at least one control signal in response to the measurement signal; adjusting the orientation of the lathe axis of rotation with respect to the rotor axis of rotation using the alignment mechanism and in response to the at least one control signal so as to improve the alignment of the lathe axis of rotation with respect to the rotor axis of rotation; and rotating the vehicle brake assembly with respect to the at least one cutting head to resurface the brake disc of the vehicle brake assembly. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13, 14)
