摘要:
A tire traction assembly for enhancing traction of vehicle tires on a slippery driving surface includes a pair of traction frames that can each be positioned on a slippery driving surface upon which a vehicle is not capable of driving due to a loss of traction. A plurality of nets is each integrated into a respective one of the traction frames. The plurality of nets includes a set of top nets and a set of bottom nets. Moreover, each of the set of top nets frictionally engages a respective vehicle tire and each of the bottom nets frictionally engages the slippery driving surface when the traction frames are positioned on the slippery driving surface. Additionally, each of the top nets and each of the bottom nets is comprised of a resilient material to resist being deformed by the weight of the vehicle tire.

A traction board for insertion under a vehicle's tire for freeing the vehicle from a stuck condition includes an elongated board body and an end plate pivotally connected to an end portion of the elongated board body. According to a further aspect, a traction board includes an elongated board body and a finger pivotally connected to the elongated board body and pivotally extending below the elongated board body in order to prevent the elongated board body from sliding rearward.

Techniques are described for determining whether snow chains are permitted to be used and to deploy snow chains based on traffic signs, weather conditions, and/or road conditions. An example method of autonomous driving operation includes performing a first determination, by a computer located in an autonomous vehicle, whether a use of snow chains is permitted based at least on a location where the autonomous vehicle is operating, performing a second determination that snow chains are required for driving the autonomous vehicle on a road, and sending, in response to the first determination indicating that the use of snow chains is permitted and in response to the second determination, instruction to snow chain devices located on the autonomous vehicle, where the instruction triggers the snow chain devices to deploy snow chains on tires of the autonomous vehicle.

An anti-skid arrangement including a friction wheel with several chains intended to be thrown under a tire in order to increase friction between the tire and the ground, and an operating arm rotatably connected to the friction wheel, wherein the operating arm is adapted to be connected to the vehicle and to bring the friction wheel into frictional engagement with the tire. The anti-skid arrangement also includes a protective member having an inner part arranged around a rotation axis of the friction wheel and between the friction wheel and the operating arm, and an outer part with two side walls abutting against opposite sides of the operating arm.The protective member prevents the chains from getting stuck between the friction wheel and the operating arm, and is simple to produce.

An anti-skid arrangement for a vehicle is disclosed. The anti-skid arrangement includes a friction wheel including a hub and a ring arranged around the hub, and a chain plate attached to the hub, wherein the chain plate includes several chains intended to be thrown under the tire in order to increase friction between the tire and the ground. The hub includes two parts clamping the ring. Further, an inner side of the ring is provided with grooves extending in a tangential direction along the ring and facing each hub part, and the two parts are provided with protrusions engaging the grooves.The engagement between the tangential grooves and the protrusions in the hub will secure the ring firmly, even when the tread of the ring is worn down.

A unit for rapid deployment and retraction of chain traction systems for vehicles includes a pneumatic cylinder having a cylindrical chamber enclosing a piston that is pneumatically-movable bidirectionally. A control rod coupled at one end to the piston passes through an end of the chamber and is coupled to a rack linearly movable within a sealed, grease-containing case. The rack is formed from a series of equally-spaced roller pins secured between parallel walls of a rack frame. The roller pins of the rack engage a sprocket affixed to a rotatable shaft to which is rigidly coupled an actuator arm of the rapidly-deployable vehicle ice and snow chain traction system. As the rack is moved back and forth, the actuator arm swings through an arc that—depending on the displacement of the control rod and the length of the rack, can be greater than 180 degrees.

A metering device for granular material, includes a housing that can be arranged inside a container for the granular material. The housing has at least one inlet for the granular material and an outlet, which outlet can be closed by a sealing element. The sealing element is arranged on a metering piston, which is preloaded by a spring and can be moved axially in a compressed-air cylinder, wherein a compressed-air connection is provided on the compressed-air cylinder such that the metering piston can be moved against the spring by compressed air and the outlet can be opened, and the spring has an at least two-stage design such that the stroke of the metering piston can be changed at least in two stages by varying the compressed air.

In a method for controlling braking torque in a two-wheeled vehicle traveling in an inclined position, the driver specifies a desired braking torque, which is divided into wheel braking torques at the front wheel and at the rear wheel in such a manner, that a steering torque resulting from the wheel braking torques is less than a limiting value.

A mobile robot configured to be widely versatile in its use. For example, the mobile robot can be configured for being used on a wide assortment of surfaces, regardless of the orientation and/or shape of the surfaces. Alternatively or in combination, the mobile robot can be configured for effective and efficient movement on the surfaces it traverses. In some cases, the mobile robot is configured with two or more component units. In some cases, the component units are configured with magnets and a control system for orientating the magnets. In some cases, one or more component couplings join the component units. In some cases, the mobile unit is configured with Mecanum wheels.
