Patent ID: 7074149

Claim:
A transmission for a wheel type working vehicle in which a mechanical transmission mechanism for mechanically transmitting power, and a hydraulic power transmission mechanism having a hydraulic pump and a hydraulic motor driven by said hydraulic pump to transmit hydraulic transmission power are provided side by side as power transmission mechanisms for transmitting power of an engine to front and rear wheels via a front and rear wheel driving output shaft, wherein an output shaft of said mechanical transmission mechanism is provided in a direction orthogonal to a vehicle longitudinal direction; wherein said front and rear wheel driving output shaft and an output shaft of said hydraulic power transmission mechanism are provided in the vehicle longitudinal direction; wherein power from the output shaft of said mechanical transmission mechanism is transmitted to said front and rear wheel driving output shaft via a bevel gear transmission mechanism; and wherein power from the output shaft of said hydraulic power transmission mechanism is transmitted to said front and rear wheel driving output shaft via a cylindrical gear transmission mechanism.
