A coupling structure of a suspension, may include a lower arm having one end portion engaged with a vehicle body, an assist knuckle in which a strut is located, a RevoKnuckle engaged with the assist knuckle, rotated independently from the assist knuckle, and configured to perform steering of a vehicle wheel, a steering input portion fixed to the vehicle body and configured to apply a steering force to the RevoKnuckle during steering, and a rotation transmission unit which is engaged with the RevoKnuckle and the steering input portion and has a length which is varied in a response to a wheel rebound of a vehicle.

A protruding portion includes a fitting portion to which an outer periphery of a cylinder is fitted. When the cylinder and a closing member are assembled into an outer cylinder, a length from a contact portion to one end side end portion of the outer cylinder is longer than a length from the other end side end portion of the cylinder to one end side end portion on an outer peripheral side of the closing member. A length from one end side end surface of the protruding portion to the contact portion is longer than a difference between the length from the contact portion of a bottom portion to one end side end portion of the outer cylinder and the length from the other end side end portion of the cylinder to one end side end portion on the outer peripheral side of the closing member.

The present invention provides a shock absorber serving as a cylinder device capable of securing a clearance between an outer tube and a peripheral member and improving bending rigidity of the outer tube. An outer tube 104 housing an inner tube 103 is provided with a pair of knuckle bracket fastening plates 110a and 110b protruding in one direction from an outer surface of the outer tube 104. The pair of knuckle bracket fastening plates 10a and 110b has wide surfaces facing each other, and the wide surfaces are provided along an axial direction of the outer tube 104. When the inside of a vehicle is defined as a virtual region I 192 and the outside of the vehicle is defined as a virtual region II 193 with a virtual line 191, which passes through a stroke center line 71 and matches the inside and outside of the vehicle, as a boundary in an orthogonal cross section at an arbitrary axial position of the outer tube 104 orthogonal to the stroke center line 71 of a piston rod 102, a cross-sectional area A.sub.i1 of the outer tube 104 in the virtual region I 192 is made larger than a cross-sectional area A.sub.o1 of the outer tube 104 in the virtual region II 193.

The disclosure relates to an electric vehicle for the transportation of persons and/or loads, having a frame structure and axle modules which are coupled to the frame structure, a front axle module and a rear axle module, to which in each case the wheels are coupled kinematically, at least one of the axle modules having a drive and an energy source. One of the axle modules has four suspension points for the attachment by means of elastic bearings to the frame structure, in each case, two suspension points forming a pair, and the pairs lying at different heights in the motor vehicle vertical direction.

A wheel carrier assembly for a front axle or rear axle of a motor vehicle, with a wheel carrier part on which a link for a control arm assembly, a fixing device for a damper strut and a recess for a wheel bearing are provided. The wheel carrier part includes an air guide device for supplying air to a disk brake assembly, which as brake parts has at least a brake disk and a brake caliper. The wheel carrier part has a circumferentially hollow wheel carrier housing part. The air guide device includes at least one air inlet opening and at least one air outlet opening directed onto a brake part.

A wheel suspension includes an axle limb which supports a wheel. The axle limb includes a first steering axle which provides a first steering angle in a specified range for the wheel, and components for connecting the axle limb to a support structure. At least one of the components includes a second steering axle which provides a second steering angle which is different than the first steering angle provided by the first steering axle. The second steering axle is selectively releasable. The components for connecting the axle limb to the support structure form a double transverse link axle which includes an upper traverse link and a lower traverse link. A support tube is arranged at a chassis-side end portion of each of the upper traverse link and the lower traverse link of the double transverse link axle. The support tube is pivotable about the second steering axle.

In a riding mower having a frame supported on front and rear wheels, a mower deck supported beneath the frame, a chair on said frame and a source of motive power also supported on said frame and including an improved suspension system with an articulating front axle that substantially isolates the front wheels from the frame of the lawnmower to thereby dampen vibrations transmitted to the operator as the vehicle traverses the ground.
