Abstract
A tailstock assembly includes a housing, a torque cell supported on the housing and configured to measure loads in a first load range, and a load cell supported on the housing and configured to measure loads in a second load range that is different from the first load range. The tailstock assembly is configured so that the torque cell can be selectively mechanically isolated from the housing. In particular, the torque cell and the load cell are supported on the housing through a low friction bearing, and the tailstock assembly can be selectively switched between a first measurement mode in which the torque cell is fixed to the housing, and a second measurement mode in which the torque cell is mechanically isolated from housing via the bearing. The tailstock assembly may be used as part of a brake dynamometer for accurately measuring both active braking torques and residual drag torques.
