OIL PUMP DRIVE MECHANISM IN SPECIALLY EQUIPED VEHICLE SUCH AS DUMP TRUCK, ETC.

摘要

PURPOSE:To reduce the number of bearing members and to enhance the transmission efficiency, by using a single shaft which is common for both output gear shaft of a PTO and drive shaft of an oil pump. CONSTITUTION:An idler gear 9 to which the rotation of an engine is transmitted through a transmission unit is journalled by means of a pair of ball bearings 9a to an idler gear shaft 8 which is secured to the lower section of the inside of a PTO1 casing 4. Further, a single shaft 10 which is used commonly for both output gear shaft 10a of the PTO1 and pump drive shaft 10b of an oil pump 2, is rotatably journalled to the center section of the inside of the PTO1 casing 4 and the center section of the inside of the casing 5 of the pump 2, by means of a ball bearing 11 in the PTO1 casing 4 and a pair of bearing bushings 12 in the casing 5.
