Front wheel speed increasing mechanism for four wheel device vehicle in turn

Abstract

Abstract PURPOSE:To reduce the operation force for a steering wheel by suppressing the application of the pressing force of a frictional plate device onto the operation force for the steering wheel by installing a mechanical type auxiliary operating mechanism, in the mechanism for increasing the speed of front wheels, interlocking with the steering of the steering wheel. CONSTITUTION:A speed increasing bevel gear 10 is installed at right angles at the top edge of a front wheel driving shaft 1. Further, the speed increasing bevel gears 44 and 45 freely fitted at the both edges of the speed increasing bevel gear 10 are meshed with a front wheel pinion bevel gear 2b installs at the rear edge of a front wheel pinion shaft 2 and a brake bevel gear 12 freely fitted onto the outer periphery of the front wheel driving shaft 1. In this constitution, a frictional plate 21 is engaged with a servoactuator 3 which is supported in turnable and slidable ways onto the inner surfaces of the front wheel drive cases 8 and 9. Further, a cam ball 4 is fitted between the servoactuator 3 and a bearing case 8. A pressing body 15 for the frictional devices 20 and 21 is installed at a part of the servoactuator 3.
