An independent suspension system includes two suspension oil cylinders, respectively arranged between wheels at two sides and a frame: and a steering mechanism, configured to be driven by a steering booster oil cylinder to drive the wheels at two sides to turn. The independent system also includes two swing links arranged corresponding to the wheels at two sides, an end at one side of each of the swing links is hinged to a wheel hub of the wheel at the corresponding side via a spherical hinge, and an end at another side of each of the swing links is hinged to a fixing member fixed below a main speed reducer via two spherical hinges respectively along a fore-and-aft direction. A crane having the independent suspension system is further provided.

A suspension device for an in-wheel motor driven wheel is provided. An upper suspension arm is pivotally supported on the vehicle body for supporting the wheel in a vehicle upper position higher than an axle. A link member pivotally connects the wheel to the upper suspension arm and has an absorber connecting portion connected to a lower end of the shock absorber. The shock absorber connecting portion is disposed in the vehicle bottom position lower than an upper end portion of the in-wheel motor unit. The shock absorber is disposed between the vehicle body and the in-wheel motor unit and inclined so as to be closer to the vehicle body toward the lower end.

A wheel suspension for a motor vehicle including a wheel carrier supporting a wheel. The wheel carrier connected via at least one upper camber link, a lower control arm, and a lateral toe link to the vehicle body or subframe. A stabilizer rod connects to the wheel carrier. The wheel suspension including a damper unit and a spring unit wherein the stabilizer rod and the damper unit connect to the wheel carrier at a common connecting point.

The invention relates to a single-shell spring control arm formed of sheet metal for a wheel suspension of a motor vehicle, with upwardly directed side limbs connected to one another by a base, with a first end section for connection to a chassis girder, with a second end section for wheel-side connection, with a spring receiving section, which is located between the two end sections and has a spring support surface formed on the base, and with a damper receiving section formed between the spring receiving section and the second end section for connecting a shock absorber. In order to achieve at relatively low component weight and favorable manufacturing costs improved stiffness with respect to high axle loads, the invention provides that a U-shaped constriction is formed between the spring support surface and the damper receiving section, which constriction extends in the base and in the side limbs.

The present invention relates to wheelchair improvements and, in particular, to a wheelchair including a monocoque structural skin according to one aspect, and a suspension assembly according to another aspect.

The invention relates to a strut rod made of composite material for a suspension of a front axle of a vehicle, including: an upper part coupled to a rod and piston assembly connected to a vehicle body; and a U-shaped lower part including two brackets for fixing a knuckle arm of the vehicle. This strut rod includes means for detecting a crack. This detection means includes at least one additional edge positioned so as to project from an outer surface of the U-shaped lower part of the strut rod in a region where a crack possibly occurs in the case of an accidental shock on a wheel of the vehicle.

The four wheel vehicle uses an electric motor (142) for driving the vehicle and a battery unit (160) for supplying electric power to the electric motor. The lower chassis (5) of the vehicle includes a pair of front side frames (10) extending linearly in a fore and aft direction with an upward slant and a progressively increasing lateral mutual spacing from a front part thereof to a rear part thereof and a plurality of cross members (14, 16, 18) connecting the front side frames to each other. The battery unit is positioned between the two front side frames such that the battery unit overlaps with the front side frames in side view. Thereby, the battery unit can be effectively protected from side impacts.

A recreational off-highway vehicle ROV includes a first connection subframe connected to a first rear subframe and a main frame, and an arm connector disposed rightward of a left upper arm and leftward of a right upper arm and supporting the right and left upper arms. A distance between first and second upper connections connecting the first rear subframe and the first connection subframe is longer than a distance between first and second lower connections connecting the main frame and the first connection subframe. A first upper end portion of a left shock absorber and a second upper end portion of a right shock absorber are disposed between the first and second upper connections in a rear view of the vehicle.

A vehicle suspension system includes a frame, a damper and a rocker arm. The frame is connected with the rocker arm through the damper, the swing part of swing arm limits the swing arm's rotation angle by matching the limit structure on the frame; the bottom of damper is provided with the universal structure, the damper is connected with the rocker arm through the universal structure, and the universal structure controls the damper in free deflection. A deviation motion of vehicle wheels on both ends by coordinating the swing arm, vibration damper, etc. to avoid the slipping and rollover due to great sides way upon vehicle steering and the lateral wheels disengagement from ground and to enhance the safety of cornering driving of vehicles.
