Estimating the term…
A transmission device (1) having a switching element, which is actuated by at least one electric component (5, 17) which is part of an actuator (4). The electric actuator component is linked to a countershaft (3) of the transmission and rotates at the speed of countershaft (3) during operation, and is functionally connected through an electric transformer rotary transformer device (15) with further enclosure mounted components of the transmission device (1). Via the transformer device (15), electric energy and/or data can be exchanged, through collector ring contacts, using inductive or capacitive coupling between the enclosure mounted components of transmission device (1) and at least one electric actuator component (5, 17) which is linked with the countershaft (3).
A transmission device having at least one shift element which is actuated by an actuator device having at least one electrical component, the at least one electrical component being coupled to a countershaft of the transmission and rotating, during operation, at a rotational speed of the countershaft, the at least one electrical component being functionally connected, via a rotary transformer of an electric transformer device, with additional elements of the transmission device that are mounted on a transmission housing for transmitting at least one of electric energy and data between the at least one electrical component and the additional elements of the transmission device.
A transmission device (1) having at least one sleeve shifting element (11) being actuated by an actuator device (4) having at least one electric actuator component (5, 17), the at least one electric actuator component (5, 17) being rotationally fixed to a countershaft (3) of the transmission and being functionally connected, via a rotary transformer (15), with additional components of the transmission device (1) that are rigidly secured to a transmission housing, the rotary transformer (15) transmitting at least one of electrical energy and electrical data, by one of an inductive or a capacitive coupling, between the additional components of the transmission device (1) and the at least one of the electric component (5, 17).
