Abstract
In a suspension assembling structure, a suspension link has an engagement hole formed in a mounting face for a spring seat. The spring seat has a protrusion formed on the lower face of a seat body and configured to be brought into engagement with the suspension link by insertion into the engagement hole. Also, the spring seat has a flange formed on the outer peripheral surface of a cylindrical portion in a manner so as to radially protrude through a clearance space defined between adjacent wires of a coil spring, and configured to hold the wire of a first turn at the lower end of the coil spring, while being kept in abutted-engagement with the upper face of the first turn.
Claims9
A suspension assembling structure comprising:
- a suspension link through which a road wheel and a vehicle body are pivotably connected to each other;
- a coil spring interleaved between the suspension link and the vehicle body in such a manner that a coil axis of the coil spring is arranged in a substantially vertical direction of the vehicle body;
- a spring seat interleaved between the suspension link and a lower end of the coil spring;
- the suspension link having an engagement hole formed in a mounting face for the spring seat;
- the spring seat comprising:
- (a) a seat body;
- (b) a protrusion formed on a lower face of the seat body and configured to be brought into engagement with the suspension link by insertion into the engagement hole;
- (c) a cylindrical portion located on an upper face of the seat body and configured to be fitted into the lower end of the coil spring;
- and
- (d) at least one flange formed on an outer peripheral surface of the cylindrical portion in a manner so as to radially protrude through a clearance space defined between adjacent wires of the coil spring, and configured to hold the wire of a first turn at the lower end of the coil spring, while being kept in abutted-engagement with an upper face of the first turn,
- wherein said at least one flange comprises two flanges formed on the outer peripheral surface of the cylindrical portion at respective circumferential positions, and
- wherein at least one of the two flanges is laid out on a straight line that passes through the coil axis and is perpendicular to an axis of oscillation motion of the suspension link on a side of the vehicle body.

A spring seat comprising:
- a seat body configured to be interleaved between a suspension link and a lower end of a coil spring;
- a protrusion located on a lower face of the seat body and configured to be brought into engagement with the suspension link;
- a cylindrical portion located on an upper face of the seat body and configured to be fitted into the lower end of the coil spring;
- and
- at least one flange formed on an outer peripheral surface of the cylindrical portion in a manner so as to radially protrude through a clearance space defined between adjacent wires of the coil spring, and configured to hold the wire of a first turn at the lower end of the coil spring, while being kept in abutted-engagement with an upper face of the first turn,
- wherein said at least one flange comprises two flanges formed on the outer, peripheral surface of the cylindrical portion at respective circumferential positions and
- wherein at least one of the two flanges is laid out on a straight line passing through a coil axis and perpendicular to an axis of oscillation motion of the suspension link on a side of a vehicle body.
