A stabilizer having a tubular shape is provided so as to extend in a widthwise direction of a vehicle and coupled to a suspension arm at opposite end portions of the stabilizer. Each of the opposite end portions includes: a first large-diameter bar portion having an outside diameter greater than an outside diameter of an intermediate portion of the stabilizer; and a second large-diameter bar portion having an outside diameter greater than the outside diameter of the first large-diameter bar portion and having a wall thickness greater than a wall thickness of the intermediate portion.

Provided is an automobile capable of improving ride quality and adjustment stability. To this end, the automobile according to the exemplary embodiment of the present invention includes: an actuator; a first stabilizer bar which has one end coupled to one end of the actuator; a second stabilizer bar which has one end coupled to the other end of the actuator; and a decoupler which couples at least one of one end of the first stabilizer bar and one end of the second stabilizer bar to the actuator.

A torsion bar unit includes a cylindrical shaped torsion bar including a fiber-reinforced composite material and extending in a first direction, a first holding member having a first groove for holding an end part of the torsion bar, and a second holding member having a second groove for holding the end part of the torsion bar at a position opposite the first groove and sandwiching and holding the end part of the torsion bar between the first groove and the second groove by overlapping the first holding member and the second holding member.

A stabilizer is a stabilizer including: a main body cylinder portion which is elastically deformable and a pair of connection plate portions respectively connected to a pair of left and right suspension devices, wherein the connection plate portion includes a pair of base material portions located on both sides in the connection plate portion in a plate thickness direction T and an alloy oxide region which is disposed between the pair of base material portions and in which alloy oxides are scattered, and wherein crystal grains constituting the pair of base material portions straddle the alloy oxide region in the plate thickness direction and the pair of base material portions are joined.

The present invention relates to all terrain vehicles having at least a pair of laterally spaced apart seating surfaces.

A vehicle including: a frame; front suspension assemblies and wheels; a rear left suspension assembly connected to the frame; a rear right suspension assembly connected to the frame; rear wheels having a wheel axis and an inner rim radius; a rear gear train; and a motor. Each rear suspension assembly including a swing arm; a shock assembly; a knuckle including: a first portion connected to a wheel hub, and a second portion extending upward from the first portion; a first link having an outward end connected to the first portion and an inward end connected to the frame; and a second link having an outward end connected to the second portion and an inward end connected to the frame, the outward end of the second link being distanced from the corresponding wheel axis by a distance greater than the inner rim radius.

A stabilizer manufacturing method includes forming a first end and a second end of a stabilizer by processing a tubular member such that each of the first end and the second end has a wall thickness equivalent to a wall thickness of a main body of the stabilizer. The first end and the second end constitutes both ends of the stabilizer, and the first end and the second end are formed by sandwiching and pressing the ends of the tubular member by two pairs of pressing members, facing directions of the two pairs of pressing members being different from each other.

A stabilizer-bar holding device includes a bracket and a body for a vehicle, which hold a stabilizer bar. A normal line that is normal to each of a pair of mounted surfaces of a pair of mounted portions of the body is inclined with respect to an up and down direction of the vehicle. A holding surface of a holder of the body has a first holding surface that is a flat surface greater than each of the pair of mounted surfaces in angle of inclination with respect to the up and down direction. An up and down plane extending in the up and down direction through a central axis of the stabilizer bar extends through the first holding surface in a state in which the stabilizer bar is held by the stabilizer-bar holding device.

A bushing device for a stabilizer includes a bracket section coupled to a subframe, a bearing section mounted on the bracket section, a bushing section coupled to the bearing section to surround a stabilizer bar, and a pair of foreign substance blocking sections respectively coupled to two ends of the bracket section so as to contact the stabilizer bar so that a gap between the stabilizer bar and the bracket section is removed to block foreign substances from entering the bracket section from an outside.

This invention pertains to sway bar systems, and a method of controlling their operation. Specifically, the present invention relates to provide a way of adjusting the response characteristics of a sway bar system by changing the structure of the typical sway bar links and regulating the modified structure by utilizing an electronically adjustable sway bar link. Said electronically adjustable sway bar link comprises a twin tube cylinder filled with mixed incompressible fluid and pressurized gas and forms a determined volume in order to host pressurized gas higher than fluid flow regulation functions, permitting a directional control valve to always remain fully submerged in incompressible fluid and to modify the fluid path between each tube of said twin tube cylinder, allowing closed or opened fluid flow operation, determined by a controlling device receiving an electronic input and piloting said directional control valve.
