Activation unit with an actuator

摘要

An activation unit is disclosed having at least one actuator having a variable length disposed around at least one first axis. The activation unit operatively interacts with an activation element mounted so that it can be bi-directionally deflected along a second axis. The front side of the actuator is indirectly or directly engaged with a first piston, which can be deflected along the first axis in a mechanically positively driven manner. The first piston has a front side facing away from the actuator which axially borders at least regions of a transfer medium on one side. The transfer medium is radially surrounded relative to a first axis by a housing radially to the first axis, and axially borders at least regionally a front side of at least one second piston. The at least second piston can be deflected in a mechanically positively driven manner, and engages the activation element directly or indirectly. An actively variable and/or passive temperature control medium is provided on and/or in the housing that is in indirect or direct thermal contact with the transfer medium.

主权项

1. An activation unit having at least one actuator of a variable length disposed around at least one first axis and which operatively interacts with an activation element which is bi-directionally movable along a second axis, comprising:
an actuator which is indirectly or directly engaged with a first piston which is movable along the first axis by a positive drive; the first piston includes a front side facing away from the actuator and axially bordering one side of a transfer medium comprising at least one elastomeric material; the transfer medium being surrounded radially by a housing relative to the first axis, bordering at least regionally another side of the transfer medium along the first axis and a front side of at least one second piston and the at least second piston being movable by a positive drive and engaging the activation element directly or indirectly; and an active variable and/or passive temperature control on and/or in the housing that is in indirect or direct thermal contact with the transfer medium for providing temperature control of the transfer medium; and wherein the temperature control is one of a fluid line which is in thermal contact with the housing and through which a temperature control medium can be conveyed, at least one thermoelectric structural component, a Peltier element and a heating element.
