摘要： A leaf spring structure is designed as a single piece to be able to change the spring rates of leaf springs under a load independently from the manufacturing material. The operating mechanism of the leaf spring allows for increasing the spring rates by deactivating the short spring, which remains between the point A and the point B, as a result of the interaction between the short spring and the long spring after a certain amount of vertical displacement in the leaf spring.

摘要： A vehicle leaf spring shackle includes pair of longitudinal plate members opposed to each other, pair of devices for connecting the pair of longitudinal plate members to each other at their opposite end portions with respective predetermined spacing distances, and between pair of longitudinal plate members, one pair of devices is coupled to a member of a vehicle body while other pair of devices is coupled to one end portion of a leaf spring device provided to suspend the vehicle body. At least one end portion of the pair of longitudinal plate members on the leaf spring device side including a thick-walled portion formed with thickness larger than other portions of the pair of longitudinal plate members, the thick-walled portion is formed by press-forming operation to press at least one end portions of the longitudinal plate members on the leaf spring device side, in direction of the end portion plane.

摘要： A vehicle spring for a spring system, includes a spring body (20) and is produced, in particular rolled, from a profiled bar (1) made of a flat steel bar, in particular spring steel, in a hot deformation process. The profiled bar (1) or the spring body (20) has at least one material recess (6) which is provided over the length of the profiled bar or the spring body at least in some regions. The cross-sectional shape of the profiled bar (1) can be the same over the entire length of the profiled bar, whereas the cross-sectional shape in the spring body (20) can vary over the length of the spring body.
