Document Type and Number:
Japanese Patent JP3981827
Kind Code:
B2
Abstract:
A wheel nut assembly includes a stud ( 1 ), a main wheel nut ( 4 ) mountable on threads ( 3 ) provided on the stud, and a retaining nut ( 6 ) engageable with threads ( 5 ) provided on the stud to prevent accidental loosening of the wheel nut ( 4 ). The threads of the wheel nut ( 4 ) and the threads for the retaining nut ( 6 ) are of opposite hand. A cap ( 11 ) is slidably mounted on the retaining nut ( 6 ) and biased into a first position by a spring ( 16 ). The cap ( 11 ) includes multi-hexagonal profiles ( 12, 14 ) for engaging hexagonal profiles ( 13, 15 ) provided on the retaining nut ( 6 ) and on the main wheel nut ( 4 ). Accordingly, in the first position, the retaining nut ( 6 ) and the main wheel nut ( 4 ) are rotationally locked to each other and because of the opposite hand of the respective threads it is not possible to remove the retaining nut. To release the retaining nut ( 6 ), the cap ( 11 ) is grasped and pulled to the limit permitted by the spring ( 16 ) to permit rotation of the retaining nut ( 6 ) and removal thereof.
