Title: Differential gear device
Inventor: MATSUOKA KAZUO
IPC: F16H48/06
Filed: 1978-07-17
Abstract: PURPOSE: To operate two drive wheels without use of any long drive shaft by directly coupling the rotary shafts of oil hydraulic pumps to the shafts of side gears and piping the oil hydraulic pumps and oil hydraulic motors directly coupled to the drive wheel axle.  
     CONSTITUTION: When a drive gear 6 is rotated by a motor 11, a gear case 8 is rotated to cause rotation of side gears 2 and 3 through pinion mate gears 4 and 5. Thus, oil hydraulic pumps 13 and 14 are rotated at a predetermined speed, and oil hydraulic motors 20 and 21 are operated by discharged oil hydraulic operating fluid from the oil hydraulic pumps 13 and 14, thus causing rotation of drive wheels 17 and 18. When the running vehicle changes the direction of tis running, a greater load is applied to either one of the side gears 2 and 3 to increase the speed of the other side gear. As a result, the discharge from the oil hydraulic pump on the side of the gear which is increased in speed is increased, whereby the outer wheel is rotated at a higher speed to effect a change of the direction of running of the vehicle.
