A method for estimating torque transmitted to a structure located downstream of a transmission system of a vehicle is disclosed. The vehicle comprises an engine for generating torque, a transmission system configured to transmit a fraction of the torque generated by the engine to a plurality of wheels of the vehicle, and a further fraction of the torque generated by the engine to the structure. The transmission system includes a shaft arrangement interposed between the engine and the structure, a planetary gearing supported by the shaft arrangement, and a transmission unit arranged in parallel to the shaft arrangement. The torque transmitted to the structure is estimated on the basis of a group of parameters which comprise torque upstream of the transmission system, twist of the shaft arrangement, and a parameter which is indicative of the ratio between an output rotational speed at an output of the transmission unit and an input rotational speed at an input of the transmission unit.

A method for calibrating a detector of a damping assembly in a vehicle. The damping assembly comprises a damper for connecting a transmission shaft of a transmission system of the vehicle to a driving shaft, the method comprising the step of applying different torques at the damping assembly by generating losses at different working conditions of the transmission system, so that the damper can be compared to a damper of a reference vehicle for each of the different working conditions.

The invention relates to mounting of a stack of Belleville springs about a shaft. The individual springs of the stack are first positioned over the shaft. A jig is then placed over the shaft and the springs and has at least one axially extending pressure bar that is radially inwardly biased to urge the inner circumferences of all the springs into contact with axially aligned points on the surface of the shaft. The springs are then compressed using a compression element while they are still urged by the pressure bar against the shaft. Finally, to retain the springs on the shaft and maintain the springs in compression, a split retaining clip is pressed onto to the shaft until it engages in a groove.
