Abstract:
The invention relates to a drive device, comprising a drive device housing with a longitudinal axis, at least one gearing assembly received in the drive device housing, with a gearing housing, which is received in the drive device housing so as to be rotatable about the longitudinal axis thereof, an engagement element received in the drive device housing and connected thereto for rotation therewith with respect to a rotation about the longitudinal axis thereof, said engagement element comprising an end face running substantially orthogonally to the longitudinal axis, which end face is in frictional and, if desired, additionally interlocking engagement with an associated counter end face of the gearing assembly or one of the plurality of gearing assemblies, and a spring, which is received in the drive device housing and prestresses the end face and the counter end face against one another.
Abstract:
An actuating device includes a base part and a part which can be moved and is coupled to the base part in a manner such that it can pivot about a pivot axis. A driving device has a cable which can be wound up on a cable drum to drive the movement of the part which can be moved. The driving device has a pull/push rod which is coupled by its one end to the part which can be moved at a distance from the pivot axis and is guided movably by its second end along a guide path, which extends approximately at right angles to the pivot axis, on the base part. In this case, the second end of the pull/push rod can be pulled by a first cable to a first end of the guide path and by a second cable to a second end of the guide path.
Abstract:
A piston/cylinder unit having a selectively inhibited movement includes a cylinder filled with a hydraulic medium and a piston arranged on a piston rod and dividing the cylinder into working spaces. A flow connection system having a flow connection is arranged between the first and second working spaces. The flow connection system includes an on-off valve having a movable valve element which opens the flow connection as a function of a position of the movable valve element. The flow connection system further includes a load-dependent valve arranged in series with the on-off valve for inhibiting complete flow through the flow connection independently from the on-off valve when a load on the piston/cylinder unit is lower than an inhibiting load.
Abstract:
A piston rod is guided in an axially movable manner within a cylinder filled with a damping medium, and a piston is arranged on the piston rod, which piston divides the cylinder into a working space on the piston-rod side and a working space remote from the piston rod. The two working spaces are connected to each other by at least one flow passage which is activated as a function of the axial position of a valve body, which is prestressed in the opening direction by a spring, the valve body being movable onto a valve seat surface into the closed position as a function of dynamic pressure and at least reducing the passage cross section of the at least one flow passage. The piston has a valve seat surface on which the valve body comes to bear with a conical closing surface in the maximally closed position.
Abstract:
Actuating system comprising an actuator with a torque-transmission element for a movable element, in particular a swing-action panel in a motor vehicle, the movable element being mounted pivotably in a basic hinge element. The actuating system has a torque support arranged functionally between the basic hinge element and the actuator, at least one key profile being made in the torque support, so that it is possible to bring about axial plug-connection assembly with the basic hinge element.
Abstract:
The pneumatic spring which holds the rear gate of a station wagon in the open position transmits electric current to heating filaments in the window of the rear gate by way of terminals on the piston rod and the cylinder of the spring, the terminals being connected by a contact spring in the cylinder cavity in the closed position of the rear gate.
Abstract:
In a pneumatic spring of adjustable length, the piston rod is sealed to the cylinder by an annular sealing disc stressed in compression between the inner cylinder wall and a rigid, tubular projection on the radial end wall of the cylinder through which the piston rod extends outward of the cylinder cavity. The sealing disc is axially longer than the projection so that it extends inward of the cavity beyond the projection and carries an annular sealing lip engaging the piston rod only under the fluid pressure in the cylinder cavity, but practically fully relieved by the annular projection from the compressive stresses.
Abstract:
A fluid damper is provided including a cylinder filled with a damping fluid, a piston base body shiftably guided in the cylinder along a stroke axis, and a valve disk spaced apart from a shell wall of the cylinder. The piston base body divides an inner space of the cylinder into a front space and a rear space along the stroke axis. In the piston base body, there is at least one channel connecting the front space to the rear space in a fluid-conducting manner. The valve disk is shiftably guided along the stroke axis between an opening position unblocking the at least one channel and a closing position closing the at least one channel. The valve disk has a central area extending radially outward from the stroke axis, the central area being free of apertures.
Abstract:
A damping apparatus for use with a solar panel array and a solar tracking device that is operatively connected to the solar panel array to control positioning of solar panels. The damping apparatus can absorb kinetic energy from movement of the solar panels and convert the kinetic energy to heat energy. The damping apparatus can include one or more sensors that collect data corresponding to the heat energy. The damping apparatus can send instructions to the solar tracking device for adjusting the position of the solar panels based on the analysis of the sensor data.
Abstract:
A damping apparatus (10) can be self-centering and include one or more precompressed and preloaded mechanical springs (16). A solar tracking apparatus (100) can include a solar panel (102) mounted on a rotating shaft (104), and a self-centering damping apparatus (50) operatively connected to the rotating shaft (104) to compensate for torque created when the solar panel (102) is rotated at an angle to horizontal. A steering assembly for a zero-turn riding lawn mower can include a pair of steering levers and a self-centering damping apparatus (50) operatively connected to the steering levers.
