<p><P>PROBLEM TO BE SOLVED: To prevent a vehicle from running uncontrollably, to prevent early wear of a braking material, and to prevent the increase of oil temperature and the loss of energy in the hydraulically driven traveling vehicle. <P>SOLUTION: The hydraulically driven traveling vehicle has hydraulic motors 51L and 51R for driving rear wheels 13L and 13R, and ball valves 52L and 52R which are flow control valves and arranged in the outlet passages of the hydraulic motors 51L and 51R. The ball valves 52L and 52R, and brake pedals 18L and 18R for operating the ball valves 52L and 52R are linked through linking mechanisms 60 so that the flow in the outlet passages of the hydraulic motors 51L and 51R may be changed according to the depressed distances of the brake pedals 18L and 18R. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
