摘要： A boat propeller drive unit of the inboard-outboard type, having a portion securely mounted in an opening in a boat transom and adapted to be drivingly connected to a motor inboard of the transom, and having a propeller leg disposed outboard of the transom. This leg is adjustable to various angles in relation to the transom by tilting about a horizontal axis and is pivotable about an upright steering support. The drive unit comprises an inductive sensor connected to a wire passing through a central bore of the steering shaft, and a magnetic core fixedly attached to the propeller leg. The magnetic core has magnetic areas separated by non-magnetic areas, and when the magnetic core is moved under the sensor, the sensor functions as a pulse counter to count a pulse of each magnetic area is moved under it. The sensor thus provides an output signal depending on the tilting angle relative to the transom, which signal indicates that angle.
摘要翻译：内侧舷外型的船用推进器驱动单元，其具有牢固地安装在船艉板的开口中的部分，并且适于被驱动地连接到艉板的内侧的电机，并且具有设置在艉板外侧的螺旋桨支脚。该腿可以通过围绕水平轴线倾斜而相对于横梁可调整到各种角度，并且可绕直立的转向支撑件枢转。驱动单元包括连接到穿过转向轴的中心孔的线的感应传感器和固定地附接到螺旋桨腿的磁芯。磁芯具有由非磁性区域分离的磁性区域，当磁芯在传感器下方移动时，传感器作为脉冲计数器计数，每个磁性区域的脉冲在其下方移动。因此，传感器根据相对于横梁的倾斜角度提供输出信号，该信号指示该角度。

摘要： A boat propeller drive unit, a so-called inboard-outboard drive unit, has a sensor which senses the trim/tilting angle of the drive unit and is designed to be connected to an electrical indicator instrument on the boat instrument panel. The sensor is a potentiometer mounted in a recess in the drive unit steering shaft. A shaft mounted in a bore in the steering shaft engages the potentiometer and is joined at its lower end to a gear, which engages a toothed segment on the helmet of the drive unit. When the drive unit is tilted, the gear is rotated by the toothed segment, and the output signal of the potentiometer varies.
摘要翻译：船用螺旋桨驱动单元（所谓的内侧舷外驱动单元）具有感测驱动单元的修剪/倾斜角的传感器，并被设计成连接到船舶仪表板上的电气指示仪。传感器是安装在驱动单元转向轴的凹部中的电位器。安装在转向轴中的孔中的轴接合电位器并且在其下端处连接到与驱动单元的头盔上的齿形段啮合的齿轮。当驱动单元倾斜时，齿轮由齿形段旋转，电位器的输出信号变化。
