The transmission includes a first shaft, a second shaft, a third shaft, and a fourth shaft. These shafts are parallel to each other. A first gear couples to the first shaft. A second gear couples to or idles around the first shaft when a first clutch is switched. A third gear meshes with the first gear and couples to the second shaft. A fourth gear couples to or idles around the second shaft when a second clutch is switched. A sixth gear meshes with the first gear and couples to the third shaft. A seventh gear couples to or idles around the third shaft when a fourth clutch is switched. A ninth gear meshes with the second gear, the fourth gear, and the seventh gear, and couples to the fourth shaft.

Transmission

A wet multiple disk clutch apparatus for use in vehicles has an input shaft; a clutch drum mounted on the input shaft; a plurality of first clutch plates positioned in the clutch drum and movable in an axial direction of the clutch drum and restricted against rotation; an output shaft; a hub fixed to the output shaft; a plurality of second clutch plates movably mounted on the hub for movement in the axial direction of the hub and restricted against rotation and with one second clutch plate positioned between each adjacent pair of first clutch plates; an actuator on the clutch drum for pressing the first and second clutch plates in the axial direction for pressing them together in clutching engagement; a plurality of guide holes opening out of the clutch drum at positions spaced at intervals around the clutch drum and each guide hole extending in the axial direction of the clutch drum, each of the first clutch plates having a plurality of pairs of projections on the outer periphery and extending into corresponding guide holes; and a plurality of spring members, one positioned in each of the gaps between respective ones of the plurality of first clutch plates and normally urging the first clutch plates in a direction so as to widen the gaps between the first clutch plates, each spring member being a pair of leaf springs with both ends bent out of the plane of the leaf spring in the same direction, and the pair of leaf springs being engaged back to back at a center portion thereof, the ends of the leaf springs abutting respective projections of the pairs of projections on the periphery of adjacent first clutch plates, the leaf springs being loosely movably mounted for movement in the same direction as the clutch plates and independently of the clutch plates.

Wet multiple disk clutch apparatus which is used in vehicles

The rotating brake plates and the fixed brake plates of a power train brake are pressed by way of the movement of the brake piston due to the supply of hydraulic pressure, thereby braking the output shaft. The guide rod is cantilever supported in the housing. The guide rod is inserted into a hole in the projecting portion at the outer periphery of the piston. The return spring is interposed between the flange portion at the end of the rod and the piston. When the hydraulic pressure is released, the brake piston is returned by the force of the return spring.
