Negative type forward and backward clutch for working vehicle and Negative type forward and backward clutch system containing the same

摘要

As a shift clutch for forward and backward shifting of a work vehicle, when hydraulic pressure is applied, the clutch disengages, and when the hydraulic pressure is released, the spring is inversely engaged by the elastic restoring force. do. The negative forward/reverse clutch for a work vehicle according to the present invention is installed in an input shaft that rotates by engine power, and is maintained in an Engage state by an elastic restoring force of a first spring installed therein and is dis-in when hydraulically applied. The first clutch assembly of a hydraulic multi-plate clutch structure that is gauged (disengage), installed on the intermediate shaft parallel to the input shaft, and the intermediate shaft, some of which are connected to a part of the first clutch assembly to transmit power, and the elasticity of the second spring installed inside The second clutch assembly of the hydraulic multi-plate clutch structure, which is maintained in the state of engagement with the restoring force and is disengaged when hydraulically applied, parallel to the input shaft and the intermediate shaft, and the other part of the first clutch assembly and the second clutch assembly The gist of the configuration is to include an output shaft provided with an output gear that is geared to enable power transmission with another part of the structure.
