Crawler controlling device for vehicle, has foot brake operating condition determination mechanism for determining actuation state of foot brake

摘要

Crawler controlling device has a foot brake operating condition determination mechanism (22) for determining the actuation state of the foot brake. The torque delivered by the clutch, is specified thus that the crawler cycle condition of the vehicle can be steered by a braking force according to the degree of the manipulation of the foot brake and a manual crawler switch (18), in order to select one of the first and second crawler mode. Crawler controlling device has an engine (2), a drive wheel, a power transmission system (13) for transferring a delivery torque from the engine to the drive wheel and a clutch (14), which is provided in the power transmission system. The first crawler mode control equipment inclusive of a condition, allows crawler cycle in a first crawler mode, where the clutch is brought into a partial interference condition, if the operating condition of the vehicle fulfills a first fixed condition, that the foot brake is not operated, which is determined by the foot brake operating condition, which is determined by the foot brake operation condition determination mechanism. Second crawler mode control equipment allows the crawler running in a second crawler mode, where the clutch is brought into a partial interference condition, that the foot brake is operated.
