  • Patent number: 11820194
    Abstract: A vehicle suspension system smoothly changes a vehicle posture with respect to a steering force and a steering angle by minimizing a kinematic roll at an initial turning stage, thereby allowing a driver to obtain the sensation of maneuvering the vehicle well. The suspension system includes a front suspension having geometry satisfying that a caster angle is +3° to +5°, a caster trail is +20 to +30 mm, an intersection point between a kingpin axis and ground is located on an inner side in a vehicle width direction of a center of a tire contact patch, and an anhedral angle of a lower arm is +2.8° to +7.2°. A rear suspension includes five links and has geometry satisfying that a virtual kingpin axis extends near the center of a tire contact patch of a rear wheel assembly and extends vertically at ?2° to 0°.

  • Patent number: 11691471
    Abstract: A five-link automobile suspension device is configured to support a lower end of a damper with a lower arm, and is capable of reducing sliding friction while ensuring a road clearance. Embodiments include a lower arm connecting a wheel support and a vehicle body, and a damper that has a lower end connected to the lower arm and is disposed to incline upward toward a vehicle-width-direction inner side in a rear view. A wall surface of the lower arm has a damper mounting portion, which supports a pivot of the damper, at a position lower than a straight line connecting a pivot on a wheel side and a pivot on a vehicle-body side of the lower arm. A bottom surface of the lower arm has a bulge formed at a position under the damper mounting portion.

  • Publication number: 20050119358
    Abstract: A resin molding for use as optical base molded by means of micro-cellular foam molding, wherein the relative density of the resin molding is within a range of from 0.99 to 0.6. The ratio (f1/f2) of the linear expansion coefficient (f1) of the resin molding in MD direction at any given portion to the linear expansion coefficient (f2) of a non-foamed resin molding in MD direction at the same portion is preferably at least 1.05. The resin molding for use as optical base having the above-mentioned relative density and linear expansion coefficient has reduced dimensional change and deviation of optical axis during use of the same.
