SUSPENSION SYSTEM PROVIDING DESIRED WHEEL KINEMATICS AT PRESCRIBED CONDITIONS
Systems are provided for suspensions that deliver desirable wheel kinematics at prescribed conditions. A system includes a vehicle body structure with an engine cradle, and an associated wheel assembly. A suspension system links the wheel assembly with the engine cradle, and includes a link coupled with the engine cradle and coupled with the wheel assembly. A joint at the link includes a flange that has an opening, an edge, and at least one undercut defined in edge of the flange. The joint allows release of the wheel assembly from the engine cradle by designed tearing between the opening and the at least one undercut. The release is initiated only under loads above a select threshold at the joint, to provide select kinematics of the wheel assembly for specific operational cases.
INDEPENDENT STEERING SYSTEM
An independent steering system includes a knuckle fastened to inside of a wheel and driven integrally with the wheel, an upper arm fastened to an upper end portion of the knuckle, a lower arm fastened to a lower end portion of the knuckle, a steering motor positioned on the lower arm, and a steering gear portion having a first end portion connected to the steering motor and a second end portion engaged to the knuckle, wherein the steering gear portion rotates integrally with the knuckle by a rotation force of the steering motor.
Independently driving wheel module and mounting method thereof
An independently driving wheel module includes: a base frame including an upper end fixed to a coupling surface of a vehicle body, and a rotation part coupled to the upper end of the base frame such that the rotation part is rotatable with respect to the upper end of the base frame; a connection link including a first end integrally coupled to the rotation part, and a second end having a shape extending downward from the first end of the connection link; a driving wheel disposed at a side of the second end of the connection link and coupled to the second end of the connection link; and a rotation plate including an upper and lower surfaces extending obliquely in misaligned directions, the rotation plate being interposed between the base frame and the vehicle body so as to be rotatable with respect to the base frame or the vehicle body.
VEHICLE SUSPENSION SYSTEM
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°. Arear 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°.
Toe link support and method of supporting a toe link
A toe link support is disclosed. In a first aspect, the toe link aperture of a hub has been bored out to receive inner and outer spacers. The spacers have bolt holes through which a toe link bolt is inserted to secure a toe link to the hub. The bolt is secured by a nut. The spacers protect the hub from damage by the bolt, and vice versa, resulting from motion of the toe link. In a second aspect, the outer spacer is further configured to be inserted into the bolt hole of the toe link, further protecting the bolt from damage. A method of supporting a toe link is also disclosed.
A BUSH PIN, A BRACKET AND A MOUNTING ASSEMBLY FOR A V-STAY FOR A VEHICLE
A bush pin is provided for a V-stay presenting two arms adapted to structurally connect an axle casing for a vehicle wheel axle to a respective of a left and right vehicle frame member, including a central bush portion and a fastening portion on each side of the central bush portion, wherein each of the fastening portions is adapted to be connected to a bracket by a fastening arrangement, wherein the bush pin includes a first contact surface on each side of the central bush portion, and displaced from the fastening portions, for contacting a corresponding contact surface of the bracket in order to transfer loads.
REAR SUSPENSION STRUCTURE OF AUTOMOTIVE VEHICLE
In a rear suspension device of an automotive vehicle, a shock absorber is provided perpendicularly to a H-shaped lower arm in a side view, respective axis of resilient bushes of pivotal portions which pivotally support upper and lower arms at a vehicle-body side are configured to be parallel to a standard line which extends in a vehicle longitudinal direction in a plan view, and an imaginary axial line which interconnects respective centers of front and rear connection portions, via which the lower arm is connected to a wheel side, is configured to extend obliquely forward and inward relatively to the vehicle longitudinal direction.
MULTI-BEARING-POINT INDEPENDENT SUSPENSION
An independent suspension comprises upper and lower fork arms, elastic elements, shock absorber and fork arm positioning pivots. The fork arms are A-shaped, front ends of the fork arms respectively connect to upper and lower suspension points of a wheel, and rear ends of the fork arms connect to a vehicle frame through the elastic elements. The shock absorber mounts on top of the front end of the upper fork arm. Vehicle frame bearing pivot points and transmission parts are constructed on peripheries of the upper and lower fork arms. The arrangement absorbs bearing elastic forces by changing directions of force and the arms of force, to form multiple points supporting multiple elastic elements, so force applied on the wheel is distributed by multiple points, increasing average running speed. Increasing the number and arrangement of the elastic elements reduces vehicle height, optimizes space utilization and improves stability and running smoothness.
CORNER MODULE APPARATUS FOR VEHICLE
Disclosed is a corner module apparatus for a vehicle. The corner module includes a knuckle coupled to a wheel bearing rotatably supporting a wheel, a drive motor, configured to generate a drive power, spaced a distance away from the wheel, a transfer shaft, disposed between the wheel and the drive motor, configured to transfer the drive power generated from the drive motor, a suspension connected to the knuckle and configured to absorb shock transferred from a road surface, and a steering system configured to support the drive motor and the suspension and to adjust a steering wheel of the wheel.
OFFSET STEERING AXIS KNUCKLE SYSTEM
A vehicle includes an assembly for providing suspension and steering for a wheel. The assembly includes an inner knuckle and a steering knuckle. The inner knuckle is coupled to an upper control arm at an upper joint and a lower control arm at a lower joint, forming a double wishbone suspension. The upper joint and the lower joint define a first axis. The steering knuckle is coupled to the inner knuckle at a steering joint that forms or otherwise defines a kingpin axis. The steering joint includes a revolute joint, a ball joint, or both. The steering knuckle is configured to be engaged with a tie-rod coupled to a steering mechanism. The kingpin axis is nearer a center of the wheel than the first axis, thus preventing or otherwise limiting torque steer. The upper and lower joints are constrained from significant steering rotation by suitable bushings, anti-steer arms, or both.
