Title: Antidive suspension unit
Inventor: HIRANO MASAHIRO
IPC: B62K25/08
Filed: 1986-05-14
Abstract: PURPOSE:To make the maintenance of valves easy and simplify the structure of a cylinder to improve the performance, by detachably mounting a valve case at a lower end portion, and containing the requisite valves wholly in the valve case. CONSTITUTION:A valve case 48 is mounted at a lower end portion,and valves are wholly contained therein. With this arrangement, the maintenance of the valves is made easy, and as no valves are arranged in an inner cylinder 38, the cylinder structure is simplified, and the stroke of a piston 39 can be ensured over the substantially entire length of the inner cylinder 38. Furthermore, as a control oil pressure opening for the valve is provided at the lower portion of the valve case 48, the lower end of a coil spring 36 fixedly engaged on an outer circumferential surface of an outer cylinder 37 does not interfere with the control oil pressure opening, and a requisite entire length of the coil spring 36 can be sufficiently ensured, thus improving the suspension performance owing to the insurance of the stroke of the piston 39 in combination therewith.
