Title: Power steering device
Inventor: ABE MASAO
IPC: B62D6/02
Filed: 1982-04-14
Abstract: PURPOSE:To extremely lower energy consumption in a steering pump, by disposing a centrifugal clutch between an engine and the pump so that the pump is driven upon low speed running but is not driven upon high speed running. CONSTITUTION:The rotary shaft 7a of an engine 7 is coupled to the input shaft 11a of a centrifugal clutch 11 through a pulley 8, a belt 9 and a pulley 10. The output shaft 11b of the entrifugal clutch 11 is coupled to a steering pump 6. A spring member 21 is disposed in a hole 12 formed in the input shaft 11a, through a supporting piece 22. The inner end of the spring member 21 urges the front end of a pressing member 23 which is therefore pressed against the large diameter part 20 of the output shaft 11b. Upon low engine speed, since centrifugal force generated in the centrifugal clutch is small, the pressing member 23 is pressed against the large diameter part 20 for carrying out power transmission. Upon high engine speed, since the centrifugal force is increased to exceed the biasing force of the spring 21, frictional force by the pressing member 23 is lowered, thereby power transmission is interrupted.
