    • PROBLEM TO BE SOLVED: To improve the operability of a parking brake in a work vehicle which preforms gear shift operation and parking brake operation by one operation lever.SOLUTION: The work vehicle has a first link mechanism 44 that interconnects an operation lever 19A with a gear shift device, and a second link mechanism 70 that interconnects and releases between the operation lever 19A and a parking brake mechanism 17. If the operation lever 19A is operated to either a gear shift path or a neutral path, the second link mechanism 70 dose not interconnect the operation lever 19A with the parking brake mechanism 17, but if the operation lever 19A is operated from the neutral path to an interconnection path, the second link mechanism 70 interconnects the operation lever 19A with the parking brake mechanism 17. Then if the brake path is operated, the parking brake mechanism 17 activates, and in addition, if the lock path is operated, a lock mechanism 18 activates.
    • 要解决的问题:提高通过一个操作杆预变换换档操作和驻车制动操作的作业车辆中的驻车制动器的可操作性。 解决方案:作业车辆具有将操作杆19A与变速装置相互连接的第一连杆机构44,以及在操作杆19A和驻车制动机构17之间互连和释放的第二连杆机构70.如果 操作杆19A被操作到换档路径或中立路径,第二连杆机构70不将操作杆19A与驻车制动机构17相互连接,而是如果操作杆19A从中立路径操作到互连 第二连杆机构70将操作杆19A与驻车制动机构17相互连接。然后,如果制动路径被操作,则驻车制动机构17启动,此外,如果锁定路径被操作,则锁定机构18激活 。 版权所有(C)2013,JPO&INPIT
