Title: Shock absorber cooling structure
Inventor: MARUYAMA AKIRA
IPC: B60G13/06
Filed: 1994-12-26
Abstract: PURPOSE: To cool a shock absorber without requiring a power source or cooling water by interposing a cooling means for cooling a damping fluid on a passage between a discharge outlet or a suction inlet provided on a tank and a cylinder. CONSTITUTION: When a shock absorber 1 repeats its expansion and contraction actions, oil generates heat and its temperature rises by the friction of respective damping valves 3c, 4a. Oil whose temperature became high moves upward by convection and is consecutively discharged to the exterior. Each time the shock absorber 1 makes a contraction action, oil is discharged to the exterior and accumulated in a tank 31 after being cooled by a heat exchanger 35. Each time the shock absorber 1 makes an expansion action, oil is returned to the interior of the shock absorber 1 from the tank 31. Thus the shock absorber 1 can be effectively cooled without requiring any power source because oil circulates through the interior of the shock absorber 1 and a cooling circuit 30 by the expansion and contraction actions of the shock absorber 1.
