ABSTRACT:
A self-leveling damper for motorcycles including a cylinder filled with hydraulic oil. A piston is slidably fitted in the cylinder. A hollowed piston rod is fitted at the lower end in the piston and projected at the upper end from the cylinder. The piston rod has a first oil path communicatable with the inside of the cylinder. A hollowed inner rod planted is fixed at the lower end on the bottom part of the cylinder and extends at the upper end in the first oil path of the piston rod. The inner rod has a second oil path communicatable with the inside of the cylinder. An upper bracket is secured to the upper end of the piston rod. A first spring seat is slidable relative to at least either the upper bracket or the cylinder. A second spring seat is secured to the other of them. A coil spring is stretched between the first and second spring seats. A hydraulic chamber is partially defined by the first spring seat. A third oil path connects the hydraulic chamber to the first and second oil paths; and a restricting mechanism restricting the return of hydraulic oil from the hydraulic chamber, the restricting mechanism being provided in the third oil path.
In the damper, the first spring seat and that one of the upper bracket and the cylinder to which the first spring seat is slidable are either made of iron at least about a sliding surface thereof and the other made of aluminum alloy.
