Abstract:
An axle driving apparatus for a vehicle having a prime mover and a belt driven stepless transmission, comprising:a pair of axles connected to respective drive wheels; a propelling transmission mechanism drivingly connected to said prime mover at a variable speed through said belt driven stepless transmission so as to transmit speed-variable output rotation of said belt driven stepless transmission to both said axles, thereby rotating said axles together at various speeds in a common direction selected from two opposite directions for forward and backward traveling of said vehicle; a steering transmission mechanism drivingly connected to said prime mover at a constant speed so as to transmit two oppositely directive output rotations to said respective axles, thereby differentially rotating said axles at various rotational speeds between said axles; an accelerator operatively connected to said belt transmission so as to change the output rotational speed of said propelling transmission mechanism; and a steering operation device operatively connected to said steering transmission so as to change the output rotational speed of said steering transmission.
