Abstract
Abstract An axle driving apparatus wherein a hydraulic motor and a hydraulic pump for a hydro-static-transmission are housed in a transmission casing of the axle driving apparatus and a center section for connecting the hydraulic motor and hydraulic pump is disposed in the transmission casing, the center section being fixed at the butt joint portion at the transmission casing, and an oil passage from the hydraulic pump to the hydraulic motor at the center section is bent at a right angle so as to extend the motor shaft in parallel to the axles, so that the rotation direction of the motor shaft conventionally changed by bevel gears is changed by the oil passages in the center section.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
136 words
An axle driving apparatus comprising a transmission casing including an upper casing joined to a lower casing; an axle disposed in parallel to the joint of said upper casing and said lower casing; a hydrostatic transmission for driving said axle, said hydrostatic transmission disposed within said transmission casing and including a hydraulic pump and a hydraulic motor; a substantially L-shaped center section fixed within said transmission casing against said lower casing, said L-shaped center section including a pump mounting surface for mounting said hydraulic pump formed on the longer part of said L-shaped center section, said pump mounting surface disposed in parallel to said axle, and a motor mounting surface for mounting said hydraulic motor formed on the shorter part of said L-shaped center section, said motor mounting surface disposed perpendicular to said pump mounting surface.
Claim 2
Dependent Claim
136 words
An axle driving apparatus comprising a transmission casing including an upper casing joined to a lower casing; an axle disposed in parallel to the joint of said upper casing and said lower casing; a hydrostatic transmission for driving said axle, said hydrostatic transmission disposed within said transmission casing and including a hydraulic pump and a hydraulic motor; a substantially L-shaped center section fixed within said transmission casing against said lower casing, said L-shaped center section including a pump mounting surface for mounting said hydraulic pump formed on the longer part of said L-shaped center section, said pump mounting surface disposed in parallel to said axle, and a motor mounting surface for mounting said hydraulic motor formed on the shorter part of said L-shaped center section, said motor mounting surface disposed perpendicular to said pump mounting surface.
Claim 3
Dependent Claim
117 words
An axle driving apparatus comprising: a transmission casing including an upper casing joined to a lower casing; an axle disposed in parallel to the joint of said upper casing and said lower casing; a hydrostatic transmission for driving said axle, said hydrostatic transmission disposed within said transmission casing and including a hydraulic pump and a hydraulic motor; a center section, including a casing mounting surface, mounted within said transmission casing to said upper casing at said casing mounting surface, said center section further including a pump mounting surface adjacent to and substantially level with said casing mounting surface for mounting said hydrostatic pump, said center section also including a motor mounting surface for mounting said hydrostatic motor.
