DRIVING DEVICE AND CONSTRUCTION MACHINE
PROBLEM TO BE SOLVED: To provide a driving device and a construction machine the operability of which can be improved even if a hydraulic motor and a rotary electromotor are used concurrently.SOLUTION: The driving device according to an embodiment comprises: a hydraulic motor and a rotary electromotor; a control part; an operation part; a rotary position detection part; and an inclination angle detection part. The hydraulic motor and the rotary electromotor drive a driven body to swivel. The control part performs drive control of the hydraulic motor and the rotary electromotor. The operation body outputs a rotational speed signal to the control part and drives the driven body to swivel at a rotational speed which is based on the rotational speed signal. The rotary position detection part detects the rotary position of the driven body. The inclination angle detection part detects the inclination angle and an inclination direction of the driven body. The control part performs the drive control of the rotary electromotor based on the detection result of the rotary position detection part and the inclination angle detection part.SELECTED DRAWING: Figure 3
