Abstract: The invention relates to an anti-skid chain, in particular for forestry and agricultural vehicles. The anti-skid chain is to permit high traction, while it has a low weight and can be easily mounted. It should simultaneously be permitted for driving on roads. To enable this, an anti-skid chain to be attached to two wheels with tires disposed one behind the other at fixed distances, in particular for the two wheels of a tandem axle, is provided according to the invention. The anti-skid chain comprises two lateral, laterally stable guide chains which are located, in the mounted state, laterally of the tread of the tires. Between the two guide chains, a chain mesh with chain strands extends. Preferably, the chain mesh is subdivided into ladder sections which are only connected to each other via the guide chain. Joint points of the guide chains are located in a radial position between the radius of the tire shoulder and the tire center. The guide chains are in particular embodied as plate link chains.

Abstract: A mixture pilot control for operating an internal combustion engine, in particular a gasoline engine of a motor vehicle, is provided. The mixture pilot control determines at least one composition of an air-fuel mixture required for a predetermined target air-fuel mixture ratio. The internal combustion engine is also provided with a lambda control with at least one lambda probe arranged in the exhaust gas flow of the internal combustion engine for determining a deviation of the actual air-fuel ratio from the predetermined target air-fuel ratio. Operating-parameter-dependent correction factors for the composition of the air-fuel mixture by the mixture pilot control are determined in dependence on the lambda control deviation, at least one of the load and/or the rotational speed and/or the temperature of the internal combustion engine, and further operating parameters of the vehicle other than the load, rotation speed or temperature of the internal combustion engine.

Abstract: A friction gear for the continuously variable speed control of an output shaft driven by an input shaft, and which includes a gear or differential gear between first and second friction wheels, and a friction disk whose rotation axis extends perpendicularly to the rotation axes of the friction wheels and is displaceable in parallel to the rotation axis of the friction wheels. The friction disk includes a recess or depression concentrically positioned in relation to the rotational axis thereof.

Abstract: An internal combustion engine has at least one cylinder and at least one gas exchange valve (1; 1a, 1b) controlled by a first cam (14) on a first camshaft (16) and by a second cam (15) on a second camshaft (17), at least one camshaft (16, 17) having an adjustable phase position in order to modify the control times of the gas exchange valve (1; 1a, 1b). The first cam (14) acts upon actuating means (6, 10) and the second cam (15) upon actuating means (6, 10) which actuate the gas exchange valve (6, 10). The actuating means (6, 10) are designed in such a way that the gas exchange valve (1) opens only when both the first cam (14) and the second cam (15) are acting upon the actuating means (6, 10). A simple structure with very high degrees of freedom for the control is achieved in that the actuating means (6, 10) comprise a lever which actuates the gas exchange valve (1; 1a, 1b) and is actuated by both cams (14, 15).

Abstract: A ring member for a tire chain has a ring body having at least one flattened portion deviating from a circular shape at an outer side of the ring member. The tire chain made from such a ring member has also stay members engaging the ring members. The ring members are arranged such that the at least one flattened portion, respectively, extends at least approximately in a longitudinal chain direction.

Abstract: The invention relates to an insulating panel fixing plug (10) having a hollow shank (12) with a holding plate (14) and having a clamping sleeve (18) protruding from the hollow shank (12). The invention provides for a closure part (24) to be arranged in the hollow shank (12), which closure part, as the insulating panel fixing plug (10) is set in position, is separated at a rupturable junction into two parts (30, 32), of which one part (30) is pulled back against a rear end of the hollow shank (12) as a drill bit (26) is withdrawn from the insulating panel fixing plug (10), and thereby closes off a cavity (16) of the hollow shank (12).
