A vehicle wheel suspension including a spring unit suspending a vehicle wheel on a vehicle body. The spring unit including a leaf spring portion extending along a Y-axis. The spring unit including a wheel carrier portion receiving a vehicle wheel. The wheel carrier portion at an end or outboard side of the leaf spring portion. The wheel carrier portion extending transversely to the leaf spring portion.

A suspension for a vehicle is configured such that, even in a situation of departing from a range (spring freedom height) in which a coil spring may be tensioned as a rebound state is added in a full rebound state, a lower end of the coil spring is coupled to a spring pad coupled to a leaf spring and continuously supported, so that the separation of the coil spring connecting a suspension arm to a body member may be prevented. The suspension includes the leaf spring provided at the suspension arm connecting a body frame to a knuckle; a spring pad coupled to the leaf spring; and the coil spring supported, at opposite ends of the coil spring, by the body member and the spring pad, the body member being located above the suspension arm.

Disclosed is a variable length shackle assembly that includes a first frame member that includes a vehicle frame mount and a rail support and a second frame member that includes a leaf spring mount and a guide rail that cooperates with the rail support to permit the first frame member to move linearly relative to the second frame member while resisting non-linear movement and a biasing member such as a spring that connects that first frame member to the second frame member.

A suspension system allows travel of a sprung mass relative to an unsprung mass. A primary stage has a primary leaf attached between the sprung mass and the unsprung mass. An auxiliary stage has an auxiliary leaf operatively attached to either the primary stage or unsprung mass. A variable engagement bracket includes a mount point, attached to the sprung mass and defining an axis, and an offset arm extending from the mount point and rotatable about the axis. The offset arm contacts the auxiliary stage at a first point at a first travel of the suspension system and at a second point at a second travel. The first point provides or defines a maximum contact span and the second provides a minimum contact span, smaller than the maximum contact span, for the auxiliary stage.

A driving robot device is provided. The driving robot device may include a plurality of suspensions configured to absorb a shock applied by a driving surface on which the driving robot device drives; a first driving part that includes a motor and is configured to adjust a strength of the plurality of suspensions; and at least one processor configured to control the first driving part to adjust the strength of the plurality of suspensions based on driving surface information with respect to a state of driving surface, and based on food information with respect to a state of food carried by the driving robot device.

A combined spring compensation suspension device for a vehicle includes a free spring, a compensation spring, a compensation spring pre-tightening device, a vibration isolation block, a light damping shock absorber and a guide mechanism. The compensation spring pre-tightening device is installed at an upper end of the compensation spring. The guide mechanism is used to connect a wheel with a vehicle body. An elastic element on the suspension device of the vehicle is composed of the free spring and the compensation spring. A suspension load has a compensation interval nearby a static deflection stroke of a suspension. When the suspension load is changed in the compensation interval, the stroke is not changed or is slightly changed. Only when the suspension load exceeds the compensation interval, the suspension stroke can be changed. Controllability and comfort of the vehicle adopting the design can be simultaneously improved.

A battery electric vehicle including an axle, a motor, a suspension, an inverter, a power cable, and a support bracket is provided. The axle extends in a vehicle-width direction. The motor is coupled to the axle, and drives the axle. The suspension supports the axle and the motor, and causes the axle and the motor to swing along a circular arc when viewed in the vehicle-width direction. The inverter is fixed to a chassis, and supplies electric power to the motor. The power cable connects the inverter and the motor. The support bracket supports the power cable, and swings together with the motor. The power cable is supported by the support bracket, at a position that is closer to the center of the circular arc than a position of half of the radius of the circular arc is when viewed in the vehicle-width direction.
