first embodiment

[0023]FIG. 1 is a block diagram of a door-opening / closing unit to which a door-opening / closing apparatus of the present invention is applied. FIG. 2 is schematic diagram of the door-opening / closing apparatus shown in FIG. 1. FIG. 3 is a front view of the door-opening / closing apparatus shown in FIG. 2. FIG. 4 is a side view of the door-opening / closing apparatus shown in FIG. 2. FIG. 5 is a vertical cross-section of a clutch shown in FIG. 3. FIG. 6A to FIG. 6C illustrates an operation of the clutch.

[0024] A door unit 1 for a vehicle comprises an opening 2a of a vehicle body 2, a door 3 which supports an upper portion of the opening 2a and closes the opening 2a, a door-opening / closing switch 4, a position detection switch 5 which detects a position of the door, a switch 6 which switches between an automatic opening / closing operation and a manual opening / closing operation of the door 3, a door-opening / closing apparatus 7, a closer 8 and a control device 9 which controls the above member...

second embodiment

[0046]FIG. 7 is a vertical cross-section of a clutch of a door-opening / closing apparatus according to the present invention. FIG. 8A to FIG. 8C illustrates an operation of the clutch.

[0047] Like the clutch of the door-opening / closing apparatus of the first embodiment, the clutch of the door-opening / closing apparatus of the second embodiment comprises a housing, an input shaft rotatably supported by a housing, and an output shaft which transmits a rotation of the input shaft in the current-carrying state and cuts off the transmission of the rotation of the input shaft in the non-current-carrying state. Since the housing and the input shaft are the same as those of the clutch of door-opening / closing apparatus of the first embodiment, they are designated with the same symbols and explanation thereof is omitted.

[0048] The clutch of the door-opening / closing apparatus according to the second embodiment is different from that of the first embodiment in that a one-way clutch 38C which perm...

Abstract

The clutch includes a drive disk, a follower disk and a brake disk. When current flows, the follower disk is connected with the drive disk to transmit a power from a driving unit to a door-opening / closing mechanism. When no current flows, the follower disk is separated from the drive disk to cut off the power transmission from the driving unit to the door-opening / closing mechanism. In a state that the drive disk and the follower disk are separated from each other, the brake disk is connected to the follower disk to brake the door-opening / closing mechanism in the opening direction of the door, and to allow the door-opening / closing mechanism to move in the closing direction of the door.

Description

BACKGROUND OF THE INVENTION [0001] 1) Field of the Invention [0002] The present invention relates to a door-opening / closing apparatus for a door of a vehicle. [0003] 2) Description of the Related Art [0004] A conventional door-opening / closing apparatus includes a clutch that is placed between a door-opening / closing mechanism and a motor that drives the door-opening / closing mechanism. The clutch can arbitrarily select a completely connected state, an incompletely connected state and a completely separated state. According to the door-opening / closing apparatus, in the completely connected state, the clutch connects the motor and the door-opening / closing mechanism to transmit the rotation of the motor to the door-opening / closing mechanism, thereby opening and closing the door. In the completely separated state, the transmission of the rotation of the motor is cut off and the door can be manually opened and closed. In the incompletely connected state, the clutch is brought into a half c...
