摘要:
An apparatus (50) and method for automatically compensating for the lateral runout between an on-car lathe apparatus (52) and a vehicle hub (44) axis including one or more stop discs (94, 96) that rotate with the drive shaft of the lathe and that can be selectively stopped from rotating with the shaft by a stop mechanism (98, 100).
摘要:
A knuckle hub assembly (10) and a method for manufacturing same whereby brake run out is produced includes a knuckle (12), a bearing (28) press fit into the knuckle (12), and a wheel hub (14) coupled to the bearing (28) and rotateable with respect to the knuckle (12). The wheel hub (14) has a flange surface (34) having a relief channel (60) formed therein. A plurality of wheel studs (44) are press fit into bolt opening (42) formed in the relief channel (60). This arrangement provides a flat flange surface (34) for mating with a rotor (42) to minimize brake run out. The knuckle hub assembly (10) is mounted into a floating tool for finish turning of the flange surface (34) to provide minimal run out and maximum flatness.

An on-car disc brake lathe system (30) for resurfacing a brake disc of a vehicle brake assembly includes a lathe body (34) with a driving motor (32), a cutting head (36) operably attached to the lathe body, and a drive shaft (68). The system also includes an alignment system (50) having an electronic controller (600), input and output adaptors (66, 82) configured to rotate with the drive shaft, one or more adjustment discs (90, 92), and an adjustment mechanism (94, 96).

摘要:
A disc brake lathe for machining a brake disc on a vehicle without removing the disc from the vehicle, but only the wheel and other parts of the brake mechanism. The disc brake lathe comprises a power drive unit (3) for rotating a brake disc on the vehicle and a lathe head (2) having at least one cutting tool (15) for machining the disc while being rotated by the power drive unit. The lathe head is adapted to be mounted on the vehicle and includes a motor for power feeding of the at least one cutting tool in each of two opposite directions during machining. Vibration of the lathe head during machining, which causes rough surface finish on the machined brake discs, is avoided or reduced by the provision of a vibration damper (50) which is attached to the lathe head for absorbing energy of vibration.
摘要:
A device (1), for holding a movable tool holder (5) at right angles to a shaft (3) for turning a brake disc (7) on a vehicle, has a coupling section (11), which is formed by a plate (13) that is fastened against a hub (17) on the shaft (3), and securing devices (19), in the form of a disc (23), for securing the tool holder (5). The device (1) also has devices for holding the tool holder (5) at right angles to the shaft (3). These devices are formed by a hinge construction, which is built up of a sphere (29), which is fastened on an ancillary shaft (33) that is fastened in the plate (13), and two scale-shaped parts (35, 37). The scale-shaped parts (35, 37) can be pressed towards each other by turning a hollow nut (39), so that they can be clamped onto the sphere (29) and block the hinge construction.
