Power steering system for vehicle

The power steering system is such that the switch-over action in the drive region of the position member (drive 10), which controls the steering movement, is achieved by a direct transmission process which approximates to the original steering wheel movement. The switch-over action is carried out through a 'steer by wire' function in which the first steering movement as desired by the driver is blocked and the steering movement is controlled exclusively via the servo system.

ABS braking system for vehicle

The ABS control system is improved using fuzzy logic which takes into account the slewing forces on the vehicle and any instability caused by braking. The braking program is modified to provide a balanced braking control by monitoring the changes in the slewing forces etc. The system monitors the changes in wheel speed, steering setting, speed etc. The system is extended by including rear wheel steering in which the steering setting of the rear wheels is compared with the steering setting of the front wheels and the dynamics of the vehicle. Fuzzy logic is also applied to the control of the rear wheel steering.

Apparatus for textile-surface processing

The invention relates to an apparatus for the spray processing of a textile surface. The apparatus as a whole is arranged within a container housing 2, in which is formed a spray station 1, through which runs a suspended conveyor 4 which guides the material to be treated past the spray nozzles 5 mounted in the frame 6. ...

Electrical layout for measuring rotational speed

Two sensor layouts are described for determining the rotational speed of a component, in particular of a vehicle wheel. Said layouts are designed in such a way that in addition to the rotational speed it is also possible to obtain the direction of rotation from the sensor signal. This requires a change to be made to only a few markings on the marker wheel of the sensor in order to evaluate the effects produced thereby so as to detect the sense of rotation.

ANTIBLOCKIERREGELSYSTEM

The invention relates to an antilock braking system (ABS) for all-wheel drive vehicles in which, in particular, a reference speed for slip control is formed. An auxiliary reference and a reference speed for the slip control are derived from the speeds of wheels with different speeds. In the event of instability, however, the increase in the auxiliary reference determines the variation in the reference speed.

Method for measuring wetting forces and a wetting solder balance

A method is described for measuring wetting forces on immersion of a substrate (1) into liquid solder, in which the substrate (1) is immersed in the solder wave (2) of a flow soldering facility (13). A wetting solder balance for carrying out the method has a container for the liquid solder, a measuring arm (3) for the substrate (1), the substrate (1) being fixed to the measuring arm (3) by means of a force transducer (4), and a lifting device for achieving a relative movement between measuring arm (3) and container. The measuring arm (3) can be lifted and lowered by means of the lifting device and the container is part of a flow soldering facility (13). ...

LENKSYSTEM

Four-wheel steering system for a motor vehicle in which at least one axle is of steerable design. The steering movements of the wheels are effected as a function of the intention of the driver and/or of variables which represent and/or influence the driving condition. According to the invention, driving conditions in which a deceleration of a certain, selectable magnitude is present are detected. During these driving conditions, steering movements which are dependent on variables which represent and/or influence the driving condition are at least reduced. In particular, steering movements in the opposite sense during braking manoeuvres starting at high speeds are prevented on vehicles with four-wheel steering. To improve directional stability during braking, steering movements of the front and rear wheels in the opposite sense which usually occur below a threshold vehicle speed are reduced or prevented if the vehicle is decelerating from a higher speed as detected by comparing wheel or ...

Pipe-mounting bearing arrangement e.g. for nuclear engineering plant

The pipe retaining mounting (1) has a bearing surface (5) for one pipe (6) and in which the mounting surface is formed by processing a metal blank by use of flame-cutting, without any mechanical reworking or re-machining. The spacing lamination (7) for receiving the pipe (6) is arranged on the bearing surface (5) and may be mfd. e.g. of austenite.

Detection and signalling of situation of antilock-braked vehicle - involve characterisation and filtering of values of transverse acceleration, angle of steering and front wheel braking pressures

The situation is assessed from determination (1) of the transverse acceleration (b sub y) from the steering angle (delta v) of the front wheels and from the braking pressures (Pv1,Pvr) thereon. A characteristic (Kby) is obtd. (4) which has a value declining from 1 towards zero as the transverse acceleration increases. The pressure difference (delta p) between the front wheel brakes is corrected and a filtered characteristic is obtd. (5) which rises to 1 and remains at that vale with increasing pressure difference. A change-of-course characteristic (Kspw(k)) is stored in a buffer memory (7a). ADVANTAGE - Friction-coefft.-split braking, curve-following, changes of course and straight-line running can be distinguished for optimal ride stabilisation making significantly fewer demands on driver.

Foldable boat for yachts etc.

The boat comprises hinges (12) which are formed as belt bands. Each band is fastened to the inside of the end wall (4) of one hull shell (2), about halfway up, and located near the top edge of the end wall (5) of the other hull shell (3). The shells overlap near the engaging side walls, so that transverse movement of the shells is prevented.The locking device is formed as a tension cable (16). The fixed end of the cable is fastened to one shell and passed over its underside. The free cable end is passed over the underside of the other shell and fastened to it. Due to this, the shells are fastened to each other rigidly along their engaging end walls.
