Abstract:
A rotary actuation system (1) for moving a door (2) with orientable wings, in particular for vehicles, said rotary actuation system (1) defining a rotation axis (3) and comprising a fluid-dynamic linear actuator (8) and a screw transmission (11) in which a stator shaft (4) and a cylindrical outer wall (6) of the screw transmission defines a pressure chamber (9) of the linear actuator (8).
Abstract:
An emergency release device (1) for a door actuation system (2) with two decouplers (3, 3') comprises a sliding body (10), movable between a locking position and a release position, a first Bowden connection interface (12), arranged on the sliding body (10), for activating and deactivating a first decoupler (3), a second Bowden connection interface (12'), arranged on the sliding body (10), for activating and deactivating a second decoupler (3'), a spring device (14), which strains the sliding body (10) permanently towards the release position, a locking mechanism (15), movable in a locking configuration, wherein it locks the sliding body (10) in the locking position, and a release configuration, wherein it releases the sliding body (10) towards the release position, a third Bowden connection interface (16), arranged on the locking mechanism (15), for displacing the locking mechanism (15) from the release configuration to the locking configuration, optionally, a release detector (18) for detecting the attainment of the release configuration and for generating a corresponding electric release signal, as well as an electric restore actuator (20), operable for displacing the sliding body (10), against the force of the spring device (14), from the release position to the locking position and for displacing the locking mechanism (15) from the release configuration to the locking configuration.
Abstract:
A door system (1) comprises a door leaf (3) for closing off an entrance opening (4), a suspension rod (10) having two opposite ends (11, 12) supported by a support structure (13), a suspension member (14) that connects the door leaf (3) to the suspension rod (10) and that can slide together with the door leaf (3) along the suspension rod (10) from an initial position corresponding to a closed position of the door leaf (3), to a final position corresponding to an open position of the door leaf (3), wherein the two opposite ends (11, 12) of the suspension rod (10) are slidable in a horizontal direction transverse to the entrance opening (4) and the suspension member (14) is slidably coupled to and guided by a non-linear upper guide (17) positioned above the suspension rod (10).
Abstract:
A rotary actuator (1) for a door (2) or ramp comprises an electric motor (3), a reduction gear (4, 5) connected to a front portion (6) of a shaft (7) of the motor (3), an output shaft (8) connected to the reduction gear (4, 5), an automatic locking brake (9) connected to a rear portion (10) of the motor shaft (7) and a decoupler (11) connected between the rear portion (10) of the motor shaft (7) and the locking brake (9) and actuatable to decouple the motor shaft (7) from the locking brake (9).
Abstract:
A rotary actuator (1) for a door (52) comprising an electric motor (3), a reduction unit (4), and a decoupler (9) connected to the reduction unit (4) and having a cam - lever mechanism for the reduction of the decoupling motion.
Abstract:
An actuating device (1) for a door (2) of a vehicle, particularly a bus, comprises: a support structure (5) comprising means (6) for connecting the device (1) to this vehicle, a door lifting unit (3) connected to the support structure (5) and which comprises a lifting member (4) movable between a lifted position and a lowered position and connectable to this door (2) such that this upward and downward movement results in a closing and opening movement of the door (2), blocking means (7) suitable to block this lifting member (4) in the lifted position, release means (8) suitable to release the blocking means (7) for allowing the lifting member (4) to be moved downward. This actuating device (1) comprises an auxiliary support device (9) distinct from the support structure (5) and removably connectable or connected thereto, wherein said blocking means (7) and said release means (8) are connected to this auxiliary support device (9).
