    摘要: The present invention relates to an electromagnetic actuator which reduces power consumption at the time of continuous operation with maintaining controllability. The electromagnetic actuator includes therein a permanent magnet (4) and a switching electromagnet coil (6) which switches a route along which this magnetic flux passes, and is constructed so that, in the case of performing the continuous operation, the magnetic flux of the permanent magnet (4) may pass along a route, which includes an armature (3), by exciting the switching electromagnet coil (6).

    摘要: A transmission employs a drum type gear selector having circumferential pads (45) employing driving pad geometry, which allows a pad to be in full contact with the drum. Each pad has its centre of gravity "Cg" on the left side of pivot point (53) so that the pad s centrifugal force "Cf" keeps the pad out of contact with the drum when it rotates in neutral. A spring (54) has one end hooked into a slot (55) of pad (45) and its other end is anchored at point (56), and also resting on the hydraulic spring at Point (S2). The spring (54) arrangement and its shape allow spring (54) to act in two major directions required for proper operation of pad (45). One action is to pull pad (45) about its pivot point (54) to a neutral position (45A) by rotating pad (45) about pivot (53) for distance "H1" moving Point (P1) into Point (P2). At the same time when the pad is pulled to position (45A), the hydraulic spring (49) is rotated about its pivot Point (S1) to position (47A). These two movements place the pad (45) in its rest position with clearance gaps "G1" and "G2" at rear and front of the pad respectively. It has to be noted that centrifugal force "Cf" is a major force, which keeps the pads in a neutral position when gears are in free operating mode.

    摘要: The invention relates to an electromagnetic clutch (4) which is used to connect a steam engine (2) to a combustion engine (3) and which comprises a first shaft (8) that can be driven by the steam engine (2), and a second shaft (9) that can be driven by the combustion engine (3), an idler gear (23) being connected to the first shaft (8) and a clutch bell (26) being connected to the second shaft (9). A freewheel (27) is provided between the idler gear (23) and the clutch bell (26) and is used to transmit a rotational movement from the idler gear (23), which is connected to the first shaft (8), onto the clutch bell (26) and allows the clutch bell (26) to freewheel in relation to the idler gear (23). An electromagnetic actuation force can furthermore generate a frictional force between the idler gear (23) and the clutch bell (26) to carry along the steam engine (2).
