  "textContent": "A hybrid four-axis drive apparatus has an engine (E/G) and a generator (G) on a first axis, a motor (M) on a second axis, a counter gear mechanism (T) on a third axis, and a differential device (D) on a fourth axis. The engine and the generator are connected to the countershaft via a differential gear device (P). The motor and the differential device are directly connected to the countershaft. The differential gear device and the countershaft are connected by a first pair of gears (41, 42). The motor and the countershaft are connected by a second pair of gears (43, 44). The countershaft and the differential device are connected by a third pair of gears (45, 46). Therefore, it becomes possible to change the gear ratio of the pair of gears (41, 42) without changing the positions of the four axes relative to one another.",
