<p><P>PROBLEM TO BE SOLVED: To provide a working machine, the turnability of which can be improved by reducing the speed of a turning-direction-side rear wheel by using one actuator and the straight advanceability of which can also be improved without increasing the cost or the weight of an electric motor. <P>SOLUTION: The working machine (1) includes: differential gears 60L, 60R each comprising a planetary gear mechanism including three elements; an input shaft (34) for transmitting the power from an engine 2 to first elements (61), (61); rear wheel transmission shafts 36L, 36R which are connected respectively to second elements (63), (63) and used respectively for transmitting the power to the rear wheels 21L, 21R; worm gear mechanisms 40L, 40R for transmitting the power respectively to third elements (64), (64); one-way clutches 50L, 50R capable of transmitting the power respectively to the worm gear mechanisms 40L, 40R; the electric motor 30 capable of transmitting the power to the one-way clutches 50L, 50R; and a control part 80 for controlling the rotative direction and rotational speed of the electric motor 30 according to an operation of a handle sensor 81. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
