Abstract
A strut suspension includes a strut whose upper end is supported by an automobile body and whose lower end is supported by a wheel side member, an upper side spring seat, a lower side spring seat fixed to the strut, and a coil spring arranged between the upper side spring seat and the lower side spring seat so as to surround the strut. In a vehicle standard state where a rudder angle provides a neutral rudder position and a vehicle is stopped. A coil center axis of the coil spring and a kingpin shaft cross each other. The coil center axis of the coil spring and a strut shaft form an angle larger than zero when being seen at a vehicle side view.
Claims5
A strut suspension, comprising:
- a strut whose upper end is supported by an automobile body and whose lower end is supported by a wheel side member;
- an upper side spring seat;
- a lower side spring seat fixed to the strut, and a coil spring arranged between the upper side spring seat and the lower side spring seat so as to surround the strut;
- wherein, in a vehicle standard state where a rudder angle provides a neutral rudder position and a vehicle is stopped,
- a coil center axis of the coil spring and a kingpin shaft cross each other, and
- the coil center axis of the coil spring and a strut shaft form an angle larger than zero when being seen at a vehicle side view.
A strut suspension, comprising:
- a strut whose upper end is supported by an automobile body and whose lower end is supported by a wheel side member;
- an upper side spring seat supported via a bearing so as to rotate against the automobile body;
- a lower side spring seat fixed to the strut;
- and
- a coil spring arranged between the upper side spring seat and the lower side spring seat so as to surround the strut;
- wherein, in a vehicle standard state where a rudder angle provides a neutral rudder position and a vehicle is stopped,
- a coil center axis of the coil spring and a kingpin shaft cross each other, and
- a bearing rotational shaft is inclined at a non-right angle against a bearing surface of the upper side spring seat or the kingpin shaft is inclined at a non-right angle against a bearing surface of the lower side spring seat, when being seen at a vehicle side view.
A strut suspension, comprising:
- a strut whose upper end is supported by an automobile body and whose lower end is supported by a wheel side member;
- an upper side spring seat supported via a bearing so as to rotate against the automobile body;
- a lower side spring seat fixed to the strut;
- and
- a coil spring arranged between the upper side spring seat and the lower side spring seat so as to surround the strut;
- wherein, in a vehicle standard state where a rudder angle provides a neutral rudder position and a vehicle is stopped,
- a coil center axis of the coil spring and a kingpin shaft cross each other, and
- a bearing rotational shaft is inclined at a non-right angle against a bearing surface of the upper side spring seat or the kingpin shaft is inclined at a non-right angle against a bearing surface of the lower side spring seat, so that the inclination directions are opposite to each other, when being seen at a vehicle side view.
A strut suspension, comprising:
- a coil spring;
- wherein a coil center axis of the coil spring and a kingpin shaft cross each other in a vehicle standard state where a rudder angle provides a neutral rudder position and a vehicle is stopped, and
- a reaction force line of the coil spring and the kingpin shaft are in a twisted state at the time of bound and rebound.
