Abstract: A torque measuring system is provided in a vehicle transmission including a clutch assembly having a two part, rotatable torque transmitting member, the two pans of the member being angularly movable relative to one another against the compression of at least one damper spring pack, and an actuator with a non rotatable cylinder for controlling the clutch. A device for radiating and receiving wave energy is arranged to irradiate the damper spring pack in order to receive a reflected modulation signal proportional to the current resonance frequency of the damper spring pack, and where the modulation signal is arranged to be converted to a torque value by a signal processing device, which torque value corresponds to the actual torque over the clutch.

Abstract: A control system and method for minimizing tire wear on vehicles such as highway trucks and tractors determines a drive wheel torque limit based on an assumed tire/road friction coefficient and at least an estimated vehicle weight. The drive wheel torque limit is used to control engine torque applied to the drive wheels.

Abstract: Method and arrangement for managing a product strategy over a period of time spanning one or more generations. The method considers people's lifestyle, life stage, generational belonging, and product characteristics in order to predict necessary changes of product requirements for one or more target groups. The arrangement includes a data processing system having a computer processing means for processing data and a storage means for storing data on a storage medium. Input data includes demographic data, as well as current and predicted product requirement data for selected lifestyles and life stages. By processing and correlating the data, a product specification is obtained that determines a product strategy for the product or products in question. The invention also relates to a method for managing a product strategy using said processing system.

Abstract: A locking member being provided with a parallel to a side face running primary recess within an internal or external rim surface. This primary recess is dividing the member into a solid supporting portion and a first portion having a side face provided with a locking member, the depth of the recess being such that the member formes one integrated single piece. The side face of the first portion is divided by secondary cuts carried through a central point of symmetry forming a number of sectors corresponding to the number of desired locking members, the secondary cuts at the same time constituting gripping surfaces for tools for the manipulation and use of the member. The locking member also provides internal or external locking to an internal or external threaded but also non-threaded surfaces.
