Problems solved by technology

In particular, the collar element needs to be reliably held in an intermediate position corresponding to the neutral position of the transmission system even when the magnetic actuator is not supplied with current, since an inadvertent excursion from the neutral position may even be dangerous

Embodiment Construction

[0022] The specific examples provided in the following description should not be construed to limit the scope and / or applicability of the appended claims. The list of examples and groups provided in the description are not exhaustive unless expressly stated otherwise.

[0023] Figure 1a , 1b and 1c illustrate a magnetic actuator 100 according to an exemplary and non-limiting embodiment. The magnetic actuator 100 comprises a first element 101 and a second element 102, the second element 102 being movable in a movement direction relative to the first element. exist Figure 1a-1c , the moving direction of the second component 102 is parallel to the z-axis of the coordinate system 199 . The first element 101 comprises a first core 103 comprising a first tooth 107 and a second tooth 108 and a first yoke connected to the first tooth and the second tooth. The first teeth 107 and the second teeth 108 are sequentially arranged in the moving direction of the second member 102 and p...

Abstract

A magnetic actuator comprises a first element (201) and a second element (202) movable with respect to the first element in a movement direction. The first element comprises teeth (207-210) successively in the movement direction, two coils in slots defined by the teeth, and a permanent magnet (211). The second element comprises teeth (212, 213) successively in the movement direction. The teeth of the first and second elements and the permanent magnet are arranged so that the second element is held by magnetic forces in each of three positions also when there are no currents in the coils. The second element can be moved between the three positions by supplying electric currents to the coils. Thus, the second element is held in any of the three positions also when current supply to the magnetic actuator is unintentionally lost.

Description

technical field [0001] The invention relates to a magnetic actuator which may, for example, but need not be part of a transmission system capable of producing different transmission ratios. Furthermore, the present disclosure relates to a transmission system comprising at least one magnetic actuator for controlling the transmission system to produce a desired one of selectable transmission ratios. Background technique [0002] In many devices and systems, drives are required to change and control the position of functional elements. Without limiting generality and for purposes of example only, we consider a transmission system comprising a first shaft provided with a first gear and a second shaft provided with a second gear. Each second gear is capable of transmitting torque to and from the second shaft and meshes with a corresponding one of the first gears. In this exemplary case, the transmission ratio between the aforementioned first and second shafts can be selected by...
