摘要： Method of operating a gearbox (6) in a vehicle by means of a gear lever (1) with the help of a computer (4). The computer controls a device that can be a friction device (8), a continuous current motor, a stepping motor or a magnetic device with controlled forces of attraction/repulsion so that the device gives adjustable perceptive indications of the movement of the gear lever. If necessary, the slowing down or blocking of the movement of the gear lever can take place with the controllable device. The invention also refers to an electronically-controlled friction device for performing the method.

摘要： A device for driving an instrument (2) step-by-step, for example an axis, which device includes a driving part (1), a space (3) between the driving part and the instrument (2), and at least one ball/roller (4) which can have different positions (A, B, C) in the space. In the different positions the ball/roller is clamped between the driving part and the instrument or is not clamped, depending on the design of the space and/or the direction of the driving part. A guiding means can be arranged in order to force the ball/roller to the different positions.

摘要： The invention concerns a system for the axial operation of a shaft (1) to one or more positions. The operation is achieved by one or more functional blocks that can be combined with each other and that can drive the shaft in either direction with variable steps, with variable speed and with variable force; or that are arranged to disengage, brake or lock the shaft (1). The functional blocks comprise a magnetic core (6) with a winding (7) together with a moving magnetic part (8) arranged on the shaft (1) and means (11.13) to achieve locking between the shaft and the locking means, for movement of the shaft together with the moving part (8) when the latter is drawn towards the core (6) on magnetisation. One special use of the invention is in association with gear-boxes of vehicles, in which combinations of units give a simple solution with great rapidity and force.
