Abstract: An assembly for supporting a vehicle chassis on a wheel of the vehicle includes a wheel attachment component for attaching the assembly to the wheel, a chassis attachment component for attaching the assembly to the vehicle chassis, and a suspension component. At least one adjustment element is coupled with the chassis attachment component and with a first portion of the suspension component, and is configured to shift the first portion of the suspension element between a plurality of operating positions relative to the chassis attachment component. A single strut bar is rigidly coupled with the wheel attachment component and with a second portion of the suspension component, and is configured to pivot relative to the chassis attachment component. The suspension component is configured to regulate motion transfer between the wheel attachment component and the chassis attachment component.

Abstract: This invention relates to a suspension particularly for every type of land vehicles and additionally for robotic applications, which can be used in bilateral operations, such as fully automated unmanned vehicles that can be driven on both sides (up and down) or in robots which can be capable of executing multi functional movements.

Abstract: The train braking device includes an air brake controller in which a plurality of friction coefficients corresponding to a brake command and a brake initial velocity are stored, an electropneumatic conversion valve that converts a pressure control signal transmitted from the air brake controller into a pneumatic signal, a relay valve that generates a predetermined brake cylinder pressure corresponding to the pneumatic signal, and a brake cylinder that controls brake shoes according to the brake cylinder pressure, wherein the air brake controller generates the pressure control signal based on the friction coefficients corresponding to the brake command and the brake initial velocity.

Abstract: A suspension mount for a vehicle axle includes first and second mount components that are positioned on opposing sides of the axle. A spring is supported by the first and second mount components. The axle is comprised of a tubular beam body that encloses a cavity. The tubular beam body has a fore wall, an aft wall, a top wall, and a bottom wall that bound the cavity. The first mount component is positioned adjacent the fore wall and the second mount component is positioned adjacent the aft wall. At least one fastener extends through the cavity and through the fore and aft walls to secure the first and second mount components to the tubular beam body.

Abstract: A vehicle axle includes an axle housing defining a cavity. The axle includes a pair of outer drive shafts, each being coaxially received in a respective housing cavity and slidable therein, each outer drive shaft defining a splined cavity. The axle includes a pair of inner drive shafts, each having a splined end coaxially coupled to a respective outer drive shaft splined cavity such that a respective outer drive shaft is slidably movable therein. A piston is attached to the inner end of each outer drive shaft and separates an inner fluid chamber from an outer fluid chamber. A fluid channel includes opposed ends in communication with respective fluid chambers. A force absorption container is in fluid communication with each fluid channel and includes a compression spring, wherein the spring is compressed when movement of the piston pushes fluid through the channel into the force absorption container.

Abstract: A steer axle for a vehicle and a method of making the same involves forming portions of a steer axle to have a three sided design. Spring seats that wrap around two of the three sides are secured to the steer axle. Plates are secured to the spring seats. The plates extend over the third surface of the steer axle. Angled spring pads are located over the plates.

Abstract: A stable wheel assembly has wheels, a connector, a wheel stand with a bracket and a resilient body. Each wheel has a center. The connector has two spindles and two protrusions. Each protrusion has a free end and an upright step integrally formed with the free end of the protrusion. The upright steps on the protrusions are mated with each other. The bracket is pivotally mounted on two protrusions with a fastener. When the scooter or electric motorcycle mounted the stable wheel assembly run on an uneven surface, the wheels is raised up and the protrusion connected to the raised wheels is pivoted around the fastener mounted inside the protrusion and bracket. Therefore, a scooter or an electric motorcycle with the stable wheel assembly can be prevented from turning over.
