A suspension apparatusincludes a leaf springin which a front end and a rear end are rotatably supported by a frameof a car and an intermediate portion thereof in a longitudinal direction is attached to an axle; and a stayhaving an engaging portionfor blocking rotation of a portion to a rear of a breaking point of the leaf springwhen the leaf springis broken at a portion to a rear of the intermediate portion thereof.

Suspension apparatus

A suspension device for suspension of an axle by an intermediate portion of a single leaf spring has first restriction device which restricts, upon breakage of the leaf spring at a position behind the intermediate portion of the spring, the rear portion of the leaf spring from tilting downwardly relative to a shackle, and a second restriction device for restriction of the shackle from pivotally moving backward beyond a predetermined angle. The first restriction device is constituted by a stopper plate on the shackle for support of the rear portion of the leaf spring from below upon breakage.

Suspension device

A suspension device for suspension of an axleby an intermediate portion of a single leaf springhas first restriction means which restricts, upon breakage of the leaf springat a position behind the intermediate portion of the spring, the rear portion of the leaf springfrom tilting downwardly relative to a shackle, and a second restriction means (retainer pawl) for restriction of the shacklefrom pivotally moving backward beyond a predetermined angle. The first restriction means is constituted by a bushwith projectionswhich is arranged at a connection between the shackleand the rear end of the leaf springfor integral rotation with the rear end of the leaf springand engages with the shackleat a predetermined rotary position.
