Title:
VEHICLE HEIGHT ADJUSTING DEVICE
Document Type and Number:
WIPO Patent Application WO/2010/074322
Kind Code:
A1
Abstract:
A displaceable spring seat (2) for supporting one end of a suspension spring (S) of a vehicle is supported by fluid pressure in an operating chamber (J). A screw pump (P) for supplying an operating fluid to the operating chamber (J) is provided with a pump chamber (L) which is defined within a cylinder (10) by a piston (11). A nut (13) is integrated with the piston (11), and a screw shaft (14) is engaged with the nut (13) through threads. When the screw shaft (14) is driven rotationally, a guide member (16) which is affixed to the cylinder (10) is engaged with the outer periphery of the nut (13) or of the piston (11) so as to screw-feed the piston (11) through the nut (13). The guide member (16) consisting of a non-metallic low-friction material reduces resistance in the driving of the piston (11), and this enhances the durability of the thread-engaged section between the nut (13) and the screw shaft (14).
