<P>PROBLEM TO BE SOLVED: To achieve miniaturization and lightening of a vehicle suspension device as an entire device capable of properly changing the camber angle according to the rolling stock run situation with a simple structure. <P>SOLUTION: An upper arm 4b constituting the vehicle suspension device is constituted of: a frame 12; a telescopic mechanism 33 comprising a pair of feed screw mechanisms 13a and 13b; an electric motor 24; a worm speed reducer 14; a gear type speed reducer 25; and a link mechanism 15. In order to change the camber angle, the electric motor 24 is energized, and screw shafts 20a and 20b constituting the feed screw mechanisms 13a and 13b are moved back and forth in the back and forth direction of the vehicle. As a result, the opening angle of link arms 29a and 29b constituting the link mechanism 15 is changed, and lengths L of both link arms 29a and 29b concerning the width direction of a vehicle body 11 are changed. In this manner, the structure to make the total length of the upper arm 4b variable can be consolidated into the upper arm 4b and the problem can be solved. <P>COPYRIGHT: (C)2013,JPO&INPIT |
