FULL CROWD DETENT DEVICE FOR A WHEEL LOADER BUCKET

摘要

The present invention relates to a full crowd detent device for a wheel loader bucket, and it is an aim of the present invention to provide a full crowd detent device for a wheel loader bucket able to increase convenience of joystick operation for the operator by providing a full-crowd detent function for fully crowding the bucket even without the user holding the bucket-operating joystick lever from the maximum dump position of the bucket up until the time of completion of the maximum full-crowd operation, which is achieved by controlling the power source of an electromagnet by comparing a sensed value for the angle of the bucket, as detected from a rotational angle sensor for sensing the angle through which the rotational shaft of the bucket has rotated, with the values of the angles of predetermined bucket positions (e.g. full-crowd and return-to-dig).
