Torque sensing device for slip-controlled brake systems

Torque detecting device for slip-controlled brake systems (ABS, TRC) for controlling the wheel brake pressure in a vehicle having an engine (10, 11) having an output shaft and with a drive train (12, 13, 14), on the one hand (10 with the engine, 11 is connected) and the other with right and left wheels (1, 9) of the vehicle, comprising: a) a wheel-turning angle sensor means (6) for detecting wheel rotational angles (θ b) an output shaft rotation angle sensor (15) (for detecting an output shaft rotation angle θ c) a torque calculating device (41) for calculating a (to the wheels 1, 9) via the drive train (12, 13, 14) applied torque (T characterized, in that the torque calculation device, the torque based on c1) (of torsional rigidities k c2) (of gear ratios i and c3) of the output shaft rotation angle (θ
