摘要:
The invention relates to an electromagnetic selection device for a two-stage planetary gear set (1) with an input shaft (2) and an output shaft (3), a sun wheel (8), a hollow wheel (11), a planet carrier (10) with planet wheels (5), a gearbox housing (6) and a sliding sleeve (14) for switching from a first gear, in which the hollow wheel (11) is coupled to the housing (6) and a second gear, in which the hollow wheel is coupled to the sun wheel. The sliding sleeve may be displaced by means of an electromagnet made from magnet coils (22, 23) and an armature (24). According to the invention, the armature (24) is arranged on the sliding sleeve (14) such as to rotate but is axially fixed.

A rotation transmission device includes an electromagnetic clutch (50) including an armature (51), a rotor (52) having an outer tubular portion (52a) and an inner tubular portion (52b), and an electromagnet (53). A bearing support tube (57) is provided at the outer end surface of a core (53b) supporting an electromagnetic coil (53a) of the electromagnet (53). A bearing (58) is mounted in the bearing support tube (57) so as to be axially fixed in position and not to be pulled out of the bearing support tube (57). The small-diameter tubular portion (52c) is provided at the end of the inner tubular portion (52b) of the rotor (52), and press-fitted in the bearing (58) such that the rotor (52) and the electromagnet (53) form a unit. This makes it easier to assemble the electromagnetic clutch (50), and to control the overlap distance between the outer tubular portion (52a) of the rotor (52) and the core (53b) of the electromagnet (53).

A clutch apparatus (8) comprises a torque limiter body (12) and a solenoid brake magnet (14). The torque limiter body is pivotable relative to the solenoid brake magnet when torque acting between the torque limiter body and the solenoid brake magnet is greater than a threshold value, and is not pivotable relative to the solenoid brake magnet when the torque is less than the threshold value. Energisation of coil assembly (20) enables the torque limiter body to pivot relative to the solenoid brake magnet.

An electromagnetic clutch includes a motor, a worm wheel rotatably driven by a motor, a rotor having an electromagnetic coil and rotatable about a same rotational axis as the worm wheel, an armature that is mounted to the worm wheel and is pulled into contact with the rotor upon application of electric power to the electromagnetic coil, so that the armature is rotated with the rotor, a cover member configured to cover the rotor and the armature, and a power supply mechanism disposed between the cover member and the rotor and connected to a power source for supplying power to the electromagnetic coil. The power supply mechanism includes a fixed frame body having a first power supply portion for receiving the power from the power source and fixed to the cover member, a rotary frame body having a second power supply portion in contact with the first power supply portion for supplying the power to the electromagnetic coil, the rotary frame body being fixed to the rotor and rotatably engaged with the fixed frame body; and a plate-like conducting member provided in the cover member, the conducting member coming into contact with a portion of the first power supply portion projecting from the fixed frame body.
