Title:
LEAF SPRING DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/085174
Kind Code:
A1
Abstract:
A leaf spring device (1) comprises a leaf spring body (11), a first eye part (12), a second eye part (13), and a coupling piece (14). The first eye part is rotatably coupled to a vehicle body (B1) about a first axis (O1) extending in a width direction of the leaf spring body, and the second eye part is rotatably coupled to the coupling piece about a second axis (O2) extending in the width direction. A central portion region of the leaf spring body in the longitudinal direction supports an axle, and the leaf spring body is provided in a manner allowing flexible deformation in the upward direction. During the process of the leaf spring body flexibly deforming upward, a connection portion (11a), of the leaf spring body, that connects with the second eye part is biased by the elastic restoral force of the coupling piece in the direction (x1) where the connecting portion initially displaces in the longitudinal direction.
