Abstract
A control device, in particular for a boat drive, which comprises a control drive, a reduction gear system (8, 11, 15/17) and a control element (2) that can be pivoted through a steering angle. The reduction gear system comprises a multi-stage toothed gear transmission (8, 11, 15/17) with a toothed wheel (10) on the drive input side, and the control drive comprises two servomotors (6) which drive the toothed wheel (10) simultaneously but whose driving action are slightly opposed to one another.
Claims12
A control device comprising:
- a control drive,
- a reduction gear system (8, 11, 15/17), and
- a control element (2) being pivotable about a steering angle,
- the reduction gear system comprising a multi-stage toothed gear transmission (8, 11, 15/17) with a toothed wheel (10) on a drive input side, and
- the control drive comprising first and second servomotors (6) which simultaneously drive the toothed wheel (10), and the first and the second servomotors (6) acting in opposition to one another.
A boat drive with a propulsion and steering unit (2), which is arranged in a hull of a boat such that the propulsion and steering unit (2) being pivotable about a vertical axis (z) and being moved by a control device (5) to produce a steering action for the boat through a steering angle, the control device comprising:
- a reduction gear system (8, 11, 15/17) and the propulsion and steering unit (2) being pivotable through the steering angle,
- the reduction gear system comprising a multi-stage toothed gear transmission (8, 11, 15/17) with a toothed wheel (10) on a drive input side and a control drive comprising first and second servomotors (6) which simultaneously drive the toothed wheel (10), and the first and the second servomotors (6) acting in opposition to one another.
A control device for a boat drive, the control device comprising:
- a reduction gear system (8, 11, 15/17), and
- a casing (2) rotatably supporting a propeller driveshaft, the casing (2) being pivotable about a steering angle,
- the reduction gear system comprising a multi-stage toothed gear transmission (8, 11, 15/17) with a toothed wheel (10) which is located on a drive input side multi-stage toothed gear transmission (8, 11, 15/17) and first and second servomotors (6), each driving a drive pinion (9, 22) which engages the toothed wheel (10), the first and the second servomotors (6) simultaneously driving the toothed wheel (10) in opposition to one another.
