A vehicle configuration wherein the center of mass of the vehicle is approximately superimposed upon the passenger and driver centers of mass when seated within the vehicle. An occupant's center of mass can be approximated using a standard center of mass position approximation, or a combination of any number of standard center of mass position approximations. The vehicle's center of mass can be approximately superimposed upon the occupant's center of mass in at least the longitudinal and vertical directions.

An All-Terrain Vehicle with a frame comprising an arcuate shape or an elevated portion with an apex. In one embodiment, the arcuate shape or elevated portion with an apex is located between a rear axis and a front axis such that there is additional clearance over a typical non arcuate frame or a flat frame for a given ride height. The frame may also provide for additional structural strength. The frame may also include the ability to attach periphery accessories such as an engine cage, a passenger cage, trailing arms, power train and transmission.

A suspension system includes a main pivot housing, a swing arm housing, a linkage assembly, and a resilient component. The main pivot housing is disposed on a lower end of a leg of a stroller. An accommodating space is formed inside the main pivot housing. The swing arm housing is pivoted to a side of the main pivot housing. A wheel of the stroller is pivoted to the swing arm housing. The linkage assembly is movably disposed in the accommodating space. The resilient component is disposed between the linkage assembly and a bracket of the stroller. The swing arm housing can be forced to drive the linkage assembly to pivot relative to the main pivot housing for compressing the resilient component, so as to absorb a shock load.

A suspension tower has: a top plate at which an upper end side of a front suspension is fixed at a fixing portion that is disposed apart from a stroke axis of the suspension; and a gradually changing rib that is provided upright from the top plate and extends from the stroke axis side toward an outer peripheral side at the top plate. The gradually changing rib has a constant level portion whose height from the fixing portion is constant, and a gradually changing portion whose height from the fixing portion is gradually decreased from the constant level portion toward the outer peripheral side. A boundary between the constant level portion and the gradually changing portion is disposed adjacent to the fixing portion.

The present invention relates to a rotary disc suspension system for connecting different components constituting a moving body, comprising: an inner disc rotatably connected to one component of the moving body; and an outer disc which is coupled to another component of the moving body and which is rotatably coupled to the inner disc while disposed to face the inner disc, and thus force applied to the moving body during traveling is converted into rotational motion from linear motion so that dynamic strain and dynamic stress of the moving body can be more actively managed, and thus, even if the moving body encounters bumpy and rugged land or sloped land when in motion, a horizontal state can be maintained without tilting.
