摘要： A multi-wheel-drive vehicle has at least six wheels, a transmission with a first brake, and a transaxle device for the front drive wheels. The transaxle device includes a drive axle, an input shaft rectangular to the drive axle for receiving power from the transmission, a drive train connecting the drive axle to the input shaft, a second brake, and a clutch device in the input shaft. The drive axle may be a pair of drive axles connected by a differential unit. The clutch device can selectively isolate the drive axle from the rotation of the input device. Further, the clutch device is engaged when the first brake is applied. Additionally, the first and second brakes may be connected such that their operation may be synchronized.

摘要： A gear retaining mechanism is provided for a transmission comprising a rotary shaft, a hub fixed on the rotary shaft, a clutch slider axially slidably fitted on the hub, and a gear relatively rotatably provided on the rotary shaft. The hub is provided on an outer periphery thereof with a male spline having an axially tapered portion. The clutch slider is provided on an inner periphery thereof with a female spline meshing with the male spline of the hub. The gear is provided on an outer periphery thereof with a male spline to mesh with the female spline of the clutch slider. The male spline of the gear includes an axially tapered portion. The clutch slider is slid along the rotary shaft and located so as to fix the gear to the rotary shaft through the hub so that the female spline meshes with the male spline of the gear.

摘要： A transaxle for auxiliary wheels of a vehicle having a main drive wheel and left and right auxiliary drive wheels, comprises: a gear to which a rotary force for driving the main drive wheel is distributed; a pair of left and right axles drivingly connected to the respective left and right auxiliary drive wheels; a pair of clutches, wherein one of the clutches is interposed between the gear and the left axle, and the other clutch is interposed between the gear and the right axle; judging means for judging whether or not the main drive wheel slips; and a shift mechanism for engaging and disengaging the pair of clutches based on the judgment of the judging means. The judging means comprises a two-way clutch interposed between the gear and the pair of axles, which is engaged when rotary speed of the gear exceeds rotary speed of at least one of the axles. Alternatively, the judging means comprises: a sensor for detecting rotary speed of the gear; a sensor for detecting rotary speed of at least one of the axles; and a controller for controlling the shift mechanism. The controller receives signals from both of the sensors so as to judge whether or not the main drive wheel slips.
