  • Patent number: 10955012
    Abstract: An electromagnetic connecting device includes a flange of a hub, an armature supported by the flange via a leaf spring, a rotor accommodating an electromagnetic coil, and an anti-vibration member. When an electric current is supplied to the electromagnetic coil, the armature moves in the axial direction of the hub against the spring force of the leaf spring, and is attracted to the rotor. The leaf spring includes a moving portion that moves in the axial direction together with the movement of the armature. The anti-vibration member is fixed to the moving portion of the leaf spring. The anti-vibration member includes a stopper that comes in contact with the flange, and a damper that comes in contact with the armature. With this configuration, an electromagnetic connecting device capable of reducing an impact sound both when the armature is attracted and released can be manufactured at a low manufacturing cost.

  • Patent number: 7798302
    Abstract: In this electromagnetic clutch, a compressive force is generated in a plate spring when an armature plate is contact with a first rotor. Therefore, a force in the direction away from the first rotor acts on a first bent portion of a plate spring. However, an extension portion of a second rotor is capable of abutting to the first bent portion from the direction opposite to the first rotor. So a stress generated in the first bent portion is dispersed to the extension portion.

  • Patent number: 7721863
    Abstract: When an armature plate is attracted to a rotor so that the turning force of the rotor is transmitted to the armature plate, the turning force of the armature plate is transmitted to a main shaft via a plate spring. An angle (hereinafter referred to as a slope angle) formed between the plate spring and the armature plate is set so as to be not smaller than 10° and not larger than 63°. Therefore, since the slope angle is larger than the slope angle (about 3°) of the general electromagnetic clutch, the torque increase effect increases about 5 percent as compared with the general electromagnetic clutch, and also an excessive pressing force of the plate spring does not develop.

    Abstract: An electromagnetically operable friction disk clutch having a electromagnet as well as having a rotor and an armature element to which the electromagnet can apply a magnetic field for interaction of the rotor and armature element, the armature element being arranged on a resting means which moves the armature element along a rotation axis of the rotor by magnetic force through a movement distance to a stop position on the rotor, and returns elastically without any magnetic forces to a position in which the armature element and the rotor can move, with respect to one another, without touching. According to the invention the resetting means comprise not only an elastic component but also a plastic component which at least partially compensates for the increase in the original movement distance resulting from wear by plastic deformation of the resetting means.

  • Patent number: 6834749
    Abstract: A drive coupling system and method of engaging/disengaging the coupling provided by a drive coupling system are disclosed. The drive coupling system includes first and second torque couplers coupled respectively to drive and driven shafts. One of the couplers includes a support and first and second members rotatably coupled to the support, where each coupler includes a respective extension and a respective plurality of gear teeth. The first and second members are capable of being respectively rotated to first and second rotational positions beyond which the first plurality of gear teeth are able to at least begin to slip out of alignment with the second plurality of gear teeth. The relative slipping of the first plurality of gear teeth with respect to the second plurality of gear teeth is limited due to contact occurring between the extensions. As the relative slipping occurs, teeth of the two members become locked.

  • Publication number: 20040211640
    Abstract: In a clutch device 1, a clutch cover assembly 8 is attached to a second flywheel assembly 5 to bias elastically a frictional connection portion 54 against a friction surface 21a of a flywheel 21. A release device 10 releases the bias toward the frictional connection portion 54 by applying a load to the clutch cover assembly 8 in an axial direction toward the engine. A support plate 39 elastically supports the second flywheel assembly 5 such that the second flywheel assembly 5 can move in a bending direction. A bending direction movement suppression mechanism 24 suppresses bending movement of the second flywheel 5 by connecting the second flywheel assembly 5 to a disk-like member 13 when the clutch cover assembly 8 receives a load toward the engine in the axial direction.

  • Patent number: 6808050
    Abstract: The invention relates to a brake disc for a rail vehicle, with which a hub body (16) and a brake ring (12) are connected to one another such that with braking procedures a thermal expansion of the brake ring (12) relative to the hub body (16) is possible. At the same time screws (15) pass through axially aligned openings in a hub flange (14) arranged on the hub body (16) and a brake ring flange (13) arranged on the brake ring (12). According to the invention the screws at their end exiting the brake ring flange (13), by way of a retaining element which, for example, may be a retaining lug (17) formed integrally on the hub body (16) or a retaining bracket fixed on the hub body, may be fixed relative to the hub body (16) so that an axially parallel position of the screws (15) and a centering of the brake ring (12) is ensured even with thermal expansions.

  • Patent number: 6692362
    Abstract: The invention concerns a driving disc for transmitting the torque from one drive unit to a hydrodynamic converter (2). The driving disc (5) has one leg (51) extending in radial direction and fastened on the output shaft (1) of the drive unit and one leg (52) extending in axial direction and fastened on supporting devices (4) of a housing (3) of the hydrodynamic converter (2). By recesses (10) spaced apart from each other in peripheral direction of the driving disc (5), there are formed in the leg (52) extending in axial direction bracket arrangements which serve to fasten the leg (52) extending in axial direction on supporting device (4) situated in the housing (3). The bracket arrangements are each formed by tongue-shaped brackets (11, 12; 11′, 12′) which seen in peripheral direction extend successively from both sides of the recess (10). The end areas of the brackets (11, 12; 11′, 12′) are each fastened on one supporting device (4).

  • Patent number: 6659254
    Abstract: A clutch disc, particularly for use between a pressure plate and a counterpressure plate in a friction clutch which is installed in the power train of a motor vehicle, has two friction linings flanking resilient carriers mounted on a washer which has a hub connectable with a torque receiving part, such as the input shaft of a change-speed transmission. The carriers are connected with reinforcing sections of the friction linings by rivets in such a way that the friction linings and the washer are movable radially relative to each other. This reduces the likelihood of excessive wear upon the friction linings in response to repeated engagement and disengagement of the clutch.

  • Patent number: 6648114
    Abstract: A brake assembly includes a flex disk brake secured to a brake device of a press clutch-brake combination. A plurality of axially flexible finger elements extends from a peripheral side of the flex disk in a bent or arcuate configuration. The finger elements extend at least in part in a circumferential direction of the flex disk generally opposite to a direction of rotation of the press crankshaft. Each finger element is secured at one end to the stationary press crown. During brake activation, the axial flexibility of each finger element accommodates axial displacement of the attached brake device as the brake device undergoes actuated movement into its braking position. The flex brake disk provides a torquing rigidity that renders it rotationally stationary.
