Abstract: A suspension for a vehicle is configured such that, even in a situation of departing from a range (spring freedom height) in which a coil spring may be tensioned as a rebound state is added in a full rebound state, a lower end of the coil spring is coupled to a spring pad coupled to a leaf spring and continuously supported, so that the separation of the coil spring connecting a suspension arm to a body member may be prevented. The suspension includes the leaf spring provided at the suspension arm connecting a body frame to a knuckle; a spring pad coupled to the leaf spring; and the coil spring supported, at opposite ends of the coil spring, by the body member and the spring pad, the body member being located above the suspension arm.

Abstract: An adjustment assembly for compensating a length variation of a spring element for a vehicle is enabled. The adjustment assembly can comprise a first adjustment element having a primary abutment surface and a primary support surface. The adjustment assembly can comprise a second adjustment element having a secondary abutment surface and a secondary support surface. The first adjustment element and the second adjustment element can be arranged adjacent to one another along an axis such that the primary abutment surface and the secondary abutment surface contact each other. The primary abutment surface and the secondary abutment surface can extend circumferentially around the axis respectively and can be sloping, such that a distance between the primary support surface and the secondary support surface is adaptable by rotating the first adjustment element and the second adjustment element relative to one another.

Abstract: A hollow coil spring is made of a hollow wire in which a terminal sealed portion is formed on an end portion of the wire. The terminal sealed portion has a rotationally symmetric shape in which an axis passing through the center of the wire is the symmetric axis. The hollow coil spring includes an end wall portion, and an end face arc-shaped curved surface. The end wall portion includes an end face perpendicular to the axis. A distal-end-center closure portion is formed on the axis at the center of the end wall portion. A spring seat includes a base member and a sheet member. An end turn portion of the hollow coil spring is in contact with the sheet member. The end face of the end turn portion is opposed to a stopper wall of the spring seat.

Abstract: An end turn portion of a coil spring includes a first portion, a second portion, and a third portion. The first portion is always in contact with a spring seat irrespective of the magnitude of a load applied to the coil spring. The second portion contacts the spring seat when the load applied to the coil spring is large, and is separated from the spring seat when the load is small. The third portion is always separated from the spring seat irrespective of the magnitude of the load. An insulating sheet made of a material having rubber elasticity is attached to a lower surface of a wire at the end turn portion by means of adhesive bonding. The insulating sheet is provided on a lower surface of a region including at least the second portion.
