摘要： The present invention provides a vehicle traveling control apparatus for a vehicle with an HST and a mechanical transmission, which are connected in tandem to each other and interposed in a traveling power transmission path between a driving power source and driving wheels. The vehicle traveling control apparatus includes a speed-change control mechanism which in turn includes a signal detection part and a control part for controlling the changing of the output speed of the HST and the shifting operation of the mechanical transmission. The signal detection part includes a load-torque detection means. The control part is designed to control the mechanical transmission and the HST based upon the detected results by the load torque detection means so that where the vehicle lies in a high load torque state, the control part downshifts the mechanical transmission to a lower speed stage, while increasing the output speed of the HST.

摘要： A first hydraulic pump P1 driven by power of an engine and a first hydraulic motor M1 are fluidly connected so as to form a closed fluid circuit. An output shaft 2 of first hydraulic motor M1 is drivingly connected with a subtransmission 3. The output power from sub-transmission 3 drives main-driving wheels 5 and also drives a second hydraulic pump P2 fluidly connected with a second hydraulic motor M2 for driving sub-driving wheels 6. A clutch 7 is interposed between an output shaft 4 of sub-transmission 3 and an input shaft 9 of second hydraulic pump P2 or on the output side of second hydraulic motor M2. Second hydraulic pump P2 or second hydraulic motor M2 has variable displacement, so that second hydraulic motor M2 is drivingly accelerated in proportion to the degree of turning operation of a steering operating tool 31. In case that a plurality of front reel mowers 8FL, 8FM and 8FR are disposed in front of the vehicle body, a pair of decelerator casings 29 are disposed on both lateral sides of transmission casing 1 for driving main-driving wheels 5. Decelerator casings 29 project horizontally forward and support main-driving wheels 5 respectively at their front portions. Middle front reel mower 8FM is disposed between left and right decelerator casings 29.

摘要： A transmission has a pair of hydraulic motors for hydraulically driving crawler type vehicles. The hydraulic motors are connected by a drive train having rotary members. The hydraulic motors are disposed such that a rotary axis of an output shaft on one hydraulic motor is offset from a rotary axis of an output shaft on the other hydraulic motor. A clutch is provided between one output shaft and another rotary member, which is coaxially disposed on the one output shaft. The clutch in accordance with the invention improves the accuracy of straight forward movement of the vehicle. In accordance with the invention, when a steering unit for steering the vehicle is moved to a steering position, for turning the vehicle, and a non-steering position, for straight forward movement of the vehicle, vehicle impact and clutch damage are reduced. The transmission can also be made more compact. In addition, a parking brake can be equipped on the other output shaft.
