摘要:
Die Erfindung betrifft eine elektromagnetische Bremse oder Kupplung, mit einem Elektromagneten (2), einem Permanentmagneten (3) und einer mit dem Elektromagneten (2) und dem Permanentmagneten (3) zusammenwirkenden Ankerplatte (4), die verdrehfest, gleichwohl aber axial verschieblich auf einem Nabenkörper (11) angeordnet ist, wobei der Elektromagnet (2) ein Magnetgehäuse (5) und eine davon aufgenommene Spule (6) aufweist, wobei das Magnetgehäuse (5) ankerplattenseitig einen einen Außenpol bereitstellenden Außenringkörper (15) und einen einen Innenpol bereitstellenden Innenringkörper (16) aufweist, dadurch gekennzeichnet, dass der Innenringkörper (16) ankerplattenseitig den Permanentmagneten (3) trägt und dass zwischen dem Innenringkörper (16) und dem Außenringkörper (15) ein als Magnetflussbrücke dienender und den Innenringkörper (16) mit dem Außenringkörper (15) verbindender Steg (17) angeordnet ist.

A rotation transmission device includes torque cams (40) provided between opposed surfaces of a flange (21) of a control retainer (16A) and a flange (25) of a rotary retainer (16B) and configured to convert an axial movement of the control retainer (16A) to relative rotational motion between the two retainers (16A and 16B). All of the torque cams (40) are circumferentially offset from all of the pillars (22) of the control retainer (16A) and all of the pillars (26) of the rotary retainer (16B), and a pair of cam grooves (41 and 42) forming each torque cam (40) are heat-treated only at their areas that are brought into contact with a ball (43) of the torque cam (40), to increase the hardness of these areas, thus improving the durability of the retainers (16A and 16B).

A device (10) for providing air under pressure to a rotating pneumatic tire is disclosed. The device comprises a pump (48, 50, 58) which in use rotates with the tire and which provides air under pressure to the tire when the pump is activated. There is a pump drive system for activating the pump upon a loss of pressure in the tire. The pump drive system includes a connecting rod (52) which is rotationally connected to the tire and an eccentric body (32) which rotates with the rod when the pump is inactive. The eccentric body is inhibited from rotating with the rod to activate the pump. Relative rotation between the rod and the eccentric body drives the pump to provide air under pressure to the tire. An electromagnetic clutch is provided which has a first plate (26) which is non-rotatable and a second plate (36) which rotates with the body. The first plate is connected to the second plate electromagnetically when the clutch is engaged to prevent rotation of the second plate and hence of the connecting rod.

An electromagnetic clutch unit (3) includes: a friction mechanism (7) including a first friction member (70) and a second friction member (71); a lock sleeve (8) connected to an input shaft member so as to be non-rotatable relative to the input shaft member, and movable in an axial direction of the electromagnetic clutch unit between a first position at which the lock sleeve is engaged with only the input shaft member and a second position at which the lock sleeve is engaged with both an output shaft member and the input shaft member; and a pressing member (90) that constitutes a magnetic path extending over the pressing member and the second friction member, and that presses the lock sleeve with the electromagnetic force to move the lock sleeve from the first position to the second position.

Brushes (20, 21), which slide on slip rings (23, 24) having power feeding terminals (51, 53) to be electrically connected with a power feed side, are provided with extensions (32, 36) extending in the radial direction of a feed core (3). The extensions (32, 36) are so formed as to be bent in a direction away from a coil bobbin (12), and third bent portions (32c, 36c) positioned at the ends are electrically connected with terminal portions (10d, 10d) of coil terminals. A mounting recess (3a) housing a power feeding unit (5) of the feed core (3) has an outer diameter (R1) made smaller than the inner diameter (R2) of the coil bobbin (12). As a result, the mounting recess (3a) can be so positioned in the feed core (3) as to be separated in the direction shown by an arrow (A) from a coil-wound portion (14) of the coil bobbin (12) by a distance (H), whereby the size of a coil rotation type electromagnetic clutch (1) can be reduced in the directions shown by arrows (A-B).

The invention relates to a motive power device for a vehicle, comprising: two electric motors (M1;M2) with a support configured to support the two electric motors, each motor (M1;M2) driving a wheel mount and a clutch (EMC) connected between the two motors (M1;M2) to drive torque between them. The motors may be supported inside the vehicle and connected to the wheel mounts using drive shafts (S1,S2).

An actuator is disclosed which can be used in multiple applications, and which provides both linear and rotary outputs. The device comprises a motor driven rotor having clutch plates (20, 42) on both sides thereof. One clutch plate includes a gear driven output, and the other clutch plate drives a linear rack (12) for the linear output. An electromagnet controls the engagement of the first and second clutches (20, 42).
