摘要： A wheel module for a vehicle includes a tire, a steering unit, a driving unit, a braking unit, and a suspension mechanism. The steering unit is configured to output a steering force for the tire. The driving unit is configured to output a driving force for the tire. The braking unit is configured to output a braking force for the tire. The suspension mechanism is supported by an upper end fulcrum and a lower end fulcrum so as to reduce vibration or impact transmitted from a road surface. An imaginary straight line extending along a vertical direction and passing through a center of the tire in a radial direction and in a width direction of the tire is defined as a tire central axis. The lower end fulcrum of the suspension mechanism is positioned away from the tire central axis when viewed from a side surface of the tire.

摘要： A shock absorber for a vehicle suspension system may include a damper tube having an axis defining an axial direction extending between a first end and a second end, a bumper cap, and a dust gaiter operably coupled to the bumper cap. The bumper cap may have a cover portion and a retention portion. The cover portion may be operably coupled to the second end of the damper tube, and the retention portion may extend along a lateral periphery of the damper tube to an opposite end of the bumper cap relative to the cover portion. The retention portion may include a continuous ring at a distal end of the bumper cap relative to the cover portion to define a limit for movement of the dust gaiter along the bumper cap in the axial direction. The continuous ring may be retained by a plurality of fixed fingers that extend from the cover portion to the continuous ring. A movable finger is disposed between each of the fixed fingers, each instance of the movable finger having a radially extending locking tab to engage the dust gaiter. Each instance of the moveable finger has a radial deflection rate of less than about 8 N/mm.

摘要： A rod-end front suspension is provided for an off-road vehicle. The rod-end front suspension comprises a spindle assembly that is pivotally coupled with an upper suspension arm by way of a first rod-end joint and pivotally coupled with a lower suspension arm by way of a second rod-end joint. A steering rod-end joint coupled with the spindle assembly pivotally receives a steering rod. An axle assembly coupled with the spindle assembly conducts torque from a transaxle to a wheel coupled with the spindle assembly. Each of the first and second rod-end joints comprises a ball rotatably retained within a casing. The ball is fastened within a recess between parallel prongs extending from the spindle assembly. A threaded shank extending from the casing is threadably fixated with the suspension arm, such that the spindle assembly may be moved with respect to the casing and the suspension arm.
