Device and method for transmitting engine power

Abstract

An engine power transmission device for improving the acceleration performance of an engine connected to a torque converter of construction machinery in accelerating from standstill, wherein a clutch (10) capable of controlling a transmission torque and a controller (15) controlling the torque transmissibility of the clutch (10) according to the rotational speed of the engine are installed between the engine (1) and the torque converter (2). In a low speed rotation area where the engine rotational speed is, for example, 1000 rpm or below, the transmission torque is variably controlled to increase according to a rise in engine rotational speed within the range of 100% or less. In a high speed rotation area where the engine rotational speed exceeds 1000 rpm, the transmission torque is maintained at 100%.
