Abstract
A steer-by-wire handwheel actuator in a vehicle is presented. The handwheel actuator comprises a driver input shaft; a gear train connected to the driver input shaft; a motor responsive to control signals from a controller and variably geared to the gear train; a electro-mechanical brake responsive to the control signals from the controller and geared to one of the driver input shaft and the gear train; and a stop mechanism attached to a housing and coupled to one of the electro-mechanical brake and the gear train.
Claims6
A steer-by-wire handwheel actuator utilizing a controller operative to accept as input thereto data from the steer-by-wire system and generate therefrom control signals in a vehicle comprising:
- a driver input shaft;
- a gear train connected to the driver input shaft;
- a motor responsive to the control signals from the controller and variably geared to the gear train, the motor including a motor shaft driven therefrom and a motor pulley connected to the motor shaft and having cogs circumferentially arranged;
- an electro-mechanical brake responsive to the control signals from the controller and geared to one of the driver input shaft and the gear train;
- and
- a stop mechanism attached to a housing and coupled to one of the electro-mechanical brake and the gear train,
- wherein the gear train is a pulley and gear train assembly, said gear train assembly including:
- a driver feedback pulley connected to the driver input shaft;
- a speed reducer pulley having cogs circumferentially arranged for positive engagement with the motor pulley cogs and being connected to the driver input shaft;
- and
- a spur gear connected to the driver input shaft.
