Abstract

A coupler for a wheel loader is used for coupling an attachment(102) to a lifting arm of the wheel loader. A bracket(100) is installed between the lifting arm and the attachment(102).The bracket's back face is pivotally connected to a lifting arm and the bracket's front face is detachably connected to the attachment(102).The attachment(102) has a pair of protrusions (104a,104b) rearwardly extending from the lower back of the attachment(102) and have locking holes pierced through their width. The bracket has a pair of receiving slots(108a,108b) formed at the lower front of the bracket and engaged with the protrusions(104a,104b).The coupler has a shaft(202),and a pair of locking pins(204a,204b) combined with the shaft by threads(216a,216b).The threads (216a,216b)formed at one end of the shaft(202) are right handed and the threads (216a,216b) formed at the other end of the shaft(202) are left handed. When users turn the shaft(202)in one direction,the locking pins (204a,204b)are extended and engaged with the locking holes(a coupling position).When users turn the shaft in the other direction,the locking pins are shortened and released from the locking holes(a release position).

Description

technical field [0001] The present disclosure relates to a wheel loader, and more particularly, to an accessory coupling for a wheel loader. Background technique [0002] The loader has equipment for coupling and decoupling attachments to the lift arms or for changing between various attachments such as buckets, tongs or forks. [0003] A coupler is used to couple the attachment to the lift arm. Hydraulically actuated replaceable pins are commonly used for locking of accessory couplings. That is, the attachment is guided such that the locking holes are positioned so that replaceable pins can pass through, and then these pins are guided by controls located in the operator's console to be hydraulically actuated and enter the holes, thereby locking the attachment with the lift arm. [0004] Hydraulically actuated locking enables relatively quick exchange of accessories without leaving the operator station, but requires various hydraulic components such as actuators, conduits ...
