    摘要： A control module for a walk behind trowel configured to detect and to prevent an uncontrolled or undesirable motion of the trowel. The trowel includes an engine configured to drive rotation of a rotor. The control module includes a gyroscope and a controller. The gyroscope is configured to provide an electrical signal representative of an angular rate of motion of a reference structure on the walk behind trowel. The controller is configured to receive the electrical signal from the gyroscope and to determine when a change in the angular rate of motion of the trowel exceeds a threshold value, and in response, to prevent the engine from driving the rotor to rotate.

    摘要： A brake (100) of a concrete finishing trowel (10) responds automatically to the cessation of drive torque delivery to the rotor to actively brake the trowel's drive train, hence inhibiting or preventing frame rotation. The brake (100) preferably takes advantages of inherent characteristics of an inclined gear (82), such as a worm of a gearbox, to permit an internal component of the gearbox to shift automatically upon the cessation of drive torque therethrough from a brake released position to a brake engaged position. In the case of a worm gear-based gearbox (40), the worm (80) is configured such that reaction forces that are normally generated by the delivery of drive torque therethrough shift the worm to release the brake during normal trowel operation. These forces are eliminated in the absence of drive torque transfer, permitting the worm to shift to a brake engaged position.

    摘要： A starter module configured to limit an engine speed of an engine for a walk behind trowel at time of startup. The walk behind trowel includes a rotor driven by the engine, a throttle to command an operating state of the walk behind trowel, and a clutch operable to selectively couple an output of the engine to the rotor. The starter module includes a sensor operable to provide a signal representative of an operating state of the trowel upon engine start-up. The starter module further includes a controller configured to receive the signal representative of the operating state of the walk behind trowel, and to prevent the clutch from engaging the engine output to drive the rotor if the detected operating state is outside of a designated range for idling operation of the engine.

    摘要翻译： 混凝土整理t刀（10）的制动器（100）自动响应驱动转矩输送到转子的动作，主动地制动t刀驱动系，从而抑制或防止框架旋转。 制动器（100）优选地具有诸如齿轮箱的蜗杆的倾斜齿轮（82）的固有特性的优点，以允许变速箱的内部部件在从制动器释放位置停止其驱动转矩时自动地移动 到制动器接合位置。 在蜗轮传动齿轮箱（40）的情况下，蜗杆（80）被构造成使得正常通过传递驱动扭矩而产生的反作用力在正常t刀操作期间使蜗杆移动以释放制动器。 在没有驱动扭矩传递的情况下，这些力被消除，允许蜗杆移动到制动接合位置。
