摘要： A clutchless belt drive system for pavement saw. The saw having an engine (16) mounted to a frame (12) via a pivot mount (14) . The engine drives a first pulley (20) , which is fixed relative to the engine. The first pulley drives a belt (22) , which in turn drives a second pulley (24) . The second pulley drives a saw blade (26) . An actuator (18) connected to the frame and to the engine so that the actuator extension rotates the engine in a first direction about the pivot mount, driving the first pulley against the belt and tautening the belt about the first pulley and the second pulley, and so that actuator retraction rotates the engine in a second direction counter to the first direction, releasing the first pulley from the belt and relaxing belt tension. A shroud (28) encircles the belt in a plane perpendicular to the line defined by the center of the first pulley and the center of the second pulley. The shroud is positioned so that when the belt tension is relaxed, the belt contacts the shroud and the resulting friction decelerates the belt.

摘要： A hybrid drive train for a self propelled power trowel includes a frame having a centerline from front to rear, an engine-generator set, a pair of rotors with trowel blades tiltably connected to the frame and positioned to support the frame above a concrete surface being finished, electric motors for driving the rotors, means for tilting each rotor toward and away from the centerline, and means for tilting a rotor fore and aft, parallel to the centerline. A rectifier and inverter in series at the engine-generator output allows engine speed to be regulated by a capacitor bank, and usage of highly efficient brushless AC synchronous motors to drive the rotors. A rechargeable battery may be connected in parallel with the capacitor bank.

摘要： An auxiliary system with purge control automatically supplies diesel exhaust fluid (DEF) to an onboard DEF tank of a diesel engine to enable prolonged unattended operation. The system includes an auxiliary DEF tank, an auxiliary DEF supply line, a controller, a pump, an air inlet, and a three-way valve configured to switch the pump inlet between the auxiliary DEF tank and air. In response to low-level DEF, the pump delivers DEF through the supply line to replenish the onboard DEF tank. The controller may automatically calculate onboard DEF tank volume based on the delivered volume of DEF, and DEF level data received from an ECM, to enable replenishment control regardless of engine make and model. In response to high-level DEF, engine stoppage, or other system fault, the controller switches the valve to air and runs the pump for a predetermined time to purge DEF from the supply line.

摘要： A self-propelled power trowel for finishing a concrete surface is equipped with reversible rotors to allow an operator to reverse the direction of rotation of rotor blades. The trowel includes a rigid frame adapted for operation over a concrete surface, a pair of rotor assemblies having rotor blades tiltably connected to the rigid frame for frictionally contacting the concrete surface and supporting the rigid frame thereabove, a prime mover mounted to the rigid frame and operatively coupled to drive the rotor blades of the rotor assemblies in opposite rotational directions. Synchronous or hydraulic motors are configured for causing, responsive to manual controls, reversal of the direction of rotation of the rotor blades.

摘要： A method for thermal management of a power trowel executable by an on-board logic controller allows operation of the trowel in normal mode in which rotor speed is determined by manual control and in which a sensed temperature of the trowel lies below a high temperature setpoint. In response to the sensed temperature exceeding the high temperature setpoint, the controller switches operation of the power trowel from normal mode to thermal management mode in which a maximum rotor speed achievable by manual control is reduced by the controller in incremental steps to allow the trowel to cool. In response to the sensed temperature reaching a low temperature setpoint, the controller increases rotor speed in incremental steps, and returns operation to normal mode when a desired rotor speed is maintained for sufficient time during which the sensed temperature remains below the low temperature setpoint.
