    摘要: A vehicle drive system including: a rotating electric machine; an output drivingly coupled to a wheel; a differential gear device provided in a power transmission path between the rotating electric machine and the output, the differential gear device including at least a first rotating element drivingly coupled to the rotating electric machine, a second rotating element drivingly coupled to the output, and a third rotating element that is selectively fixed by a one-way clutch to a non-rotating member and that is selectively fixed by a friction brake to the non-rotating member; and a clutch that selectively couples together two of the first rotating element, the second rotating element, and the third rotating element.

    摘要: An automatic transmission (3) of a vehicle having a central synchronization device (8) with at least one shift element (33; 9, 10) assigned to a transmission input shaft (32; 6, 7) and being a friction locking brake, an actuating device (14) driven by supplying energy, and at least one transmission region (34; 12, 13) disposed between the brake and a transmission output shaft (30), an operative connection between the transmission input shaft and the transmission output shaft and different transmission ratios are producible over the at least one transmission region. The brake is transferable with the operative connection and the actuating device (14) into an operating state in which a transmission input shaft (6) interacting with the brake (33; 9, 10), is held in a rotationally fixed manner by the brake (33; 9, 10), wherein the brake (33; 9, 10) is held by the actuating (14) without any energy infeed.

    摘要: A work apparatus having a work tool and having a combustion engine which drives the work tool has a start enrichment device for the combustion engine and a braking arrangement for the work tool. The work apparatus has an operating mode selector for actuating the start enrichment device. The start enrichment device actuates the braking arrangement in at least one start position. Low actuating forces and a simple configuration are achieved when the braking arrangement is a differential band brake.

    摘要: Motion control systems, devices, and methods are operable for controlling rotary motion of an actuated device. In one aspect, a motion control device is coupled between an external motive input (200) and a rotary output device (300). The motion control device has a brake core (110) configured to produce an electromagnetic field when an electric current is applied. A brake band (130) made of a magnetically responsive material surrounds the brake core (110) and is coupled to the brake core (110) when the electric current is applied. A rotor (120) that is coupled to both the external motive input (200) and the rotary output surrounds at least the perimeter of the brake band (130) and is coupled to the brake band (130) for rotation together. When the electric current is applied, the rotor (120) and the brake core (110) are thus rotatably locked together to control rotary motion generated by actuating forces imparted by the external motive input (200).
