Abstract

A mixer drum driving apparatus is provided with the aim to stably supply the working fluid discharged from an auxiliary fluid pressure pump to a mixer drum when the apparatus is at an idling stop. The mixer drum driving apparatus (100) includes: a hydraulic pump 5 driven by a running engine (3) of the vehicle; a hydraulic motor 6 configured to rotationally drive the mixer drum (2) by being operated by the working fluid discharged from the hydraulic pump (5), a control valve (8) configured to control the flow of the working fluid from the hydraulic pump (5) to the hydraulic motor (6); an electric motor (11) rotated by the electricity during idling stop of the running engine (3), an auxiliary hydraulic pump (12) driven by the rotation of the electric motor (11), the auxiliary hydraulic pump (12) discharging the working fluid and operating the hydraulic motor (6); and a check valve (14) configured to prevent the backflow of the working fluid from the control valve (8) toward the hydraulic pump (5).
