Document Type and Number:
Japanese Patent JP2015167491
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a slope work vehicle wheel that enables self-traveling in a paved public road in addition to a non-paving road surface and a slope.SOLUTION: A slope work vehicle wheel is characterized as follows: the wheel includes protrusions such as claws 2 protruding from an outer circumference of a wheel body part 1; the claws 2 are substantially V-shaped, and the base part is turnably pivoted in the circumference direction of the wheel to the wheel body part 1; tension springs 3 are stretched between the wheel body part 1 and the middle parts of the claws 2; the claws 2 are maintained in the state of being rotated in the direction protruding from the wheel body part 1 by the biasing force of the tension springs 3 when the wheel body part 1 rotates in the bending direction of the V-shaped claws 2; and the claws 2 are configured so as to be turned in the direction retracting from the wheel body part 1 such that a contact pressure with a road surface resists the biasing force of the tension springs 3 when the wheel body part 1 rotates in the reverse direction with the bending direction of the V-shaped claws 2, and thereby the claws 2 are configured so as to be retractable from the wheel body part 1.
