Abstract

Disclosed is a tracked vehicle direction control valve comprises a main control valve, a valve handle is arranged at the lower end of the main control valve, a long guide rod is arranged on one side of the valve handle, a fixing disc is arranged at the upper end of the long guide rod, a reversing plate is arranged at the lower end of the fixing disc, and a rotating shaft is arranged at the lower end of the reversing plate. By arrangement of the multi-connecting-rod control mechanism, people can control the vehicle running at a high speed conveniently, huge impact caused by sudden acceleration and deceleration is avoided, the service life of the motor is prolonged, the personal safety of a user is protected, operation difficulty is lowered, and operation comfort is improved; by means of the multi-connecting-rod control mechanism, a user can control left and right running of the tracked vehicle with one hand, operation is easy, and the tracked vehicle can be applied to an open system and a closed system and can be used by people conveniently.

Description

technical field [0001] The invention relates to the field of direction control mechanisms, in particular to a direction control valve of a crawler vehicle. Background technique [0002] In the current stage of hydraulically driven tracked vehicles, the open system relies on the opening of the spool to control the speed of the tracked vehicle. The larger the opening of the spool, the faster the tracked vehicle, and the smaller the opening, the slower the tracked vehicle. , when the spool opening is zero, the vehicle brakes. Generally, two valves are used to control the left and right tracks, one valve controls the left track, and the other valve controls the right track. Push the two valve stems at the same time when moving forward, and pull the two valve stems at the same time when going backward. When turning in place, push one handle and pull the other. During travel, the push or pull stroke of a valve stem can be reduced to slow down the speed of the track in the desire...
