Abstract
A pivot unit includes a housing and a drive motor moveably connected to the housing. The drive motor includes a cylinder housing at least partially defining a cylinder bore. A piston is disposed within the cylinder bore. A first piston rod has a proximal end attached to a first side of the piston and a distal end attached to the housing. The cylinder housing is moveable along the first piston rod relative to the piston and the housing between a first cylinder housing position and a second cylinder housing position. A drive linkage is fixedly attached to the cylinder housing for concurrent movement with the cylinder housing relative to the piston and the housing.
Claims16
A pivot unit comprising:
- a housing;
- a drive motor comprising:
- a cylinder housing at least partially defining a cylinder bore;
- a piston disposed within the cylinder bore;
- and
- a first piston rod having a proximal end attached to a first side of the piston and a distal end attached to the housing, the cylinder housing moveable along the first piston rod relative to the piston between a first cylinder housing position and a second cylinder housing position;
- a drive linkage fixedly attached to the cylinder housing for concurrent movement therewith;
- a pivot head connected to the drive linkage, the pivot head rotatable about a pivot axis relative to the housing between a first pivot head position and a second pivot head position in response to movement of the cylinder housing between the first cylinder housing position and the second cylinder housing position;
- and
- a second piston rod have a proximal end fixedly attached to a second side of the piston opposite the first side of the piston and a distal end fixedly attached to the housing, wherein the cylinder housing is moveable along the second piston rod between the cylinder housing first position and the cylinder housing second position.
A pivot unit comprising:
- a housing;
- a drive motor comprising:
- a cylinder housing at least partially defining a cylinder bore;
- a piston disposed within the cylinder bore;
- and
- a first piston rod having a proximal end attached to a first side of the piston and a distal end attached to the housing, the cylinder housing moveable along the first piston rod relative to the piston between a first cylinder housing position and a second cylinder housing position;
- a drive linkage fixedly attached to the cylinder housing for concurrent movement therewith;
- a pivot head connected to the drive linkage, the pivot head rotatable about a pivot axis relative to the housing between a first pivot head position and a second pivot head position in response to movement of the cylinder housing between the first cylinder housing position and the second cylinder housing position;
- and
- a drive pulley attached to the pivot head for concurrent rotation therewith about the pivot axis, the drive linkage comprising a drive belt engaging the drive pulley, the drive belt fixedly connected to the cylinder housing so as to move in unison with the cylinder housing relative to the piston.
A pivot unit comprising:
- a housing;
- a slide rail attached to the housing;
- a drive motor slidably attached to the slide rail, the drive motor moveable along the slide rail relative to the housing between a first drive motor position and a second drive motor position;
- and
- a drive linkage attached to the drive motor, wherein the drive linkage moves in unison with the drive motor.
