摘要:
A circular knitting machine for producing knitted fabrics with combed-in fibers, comprising a needle cylinder, at least one carding device with a comb-in wheel and an extraction device for waste fibers, which produces knitted facbrics of a high quality and requires as little maintenance as possible. The extraction device has at least one extraction nozzle for generating a directional extraction flow.

For the determination of the friction/slip characteristics of the tires of a road vehicle which is equipped with an antilock system designed for an individual wheel control, in an initial phase of a controlled braking, only the wheel brake of an individual vehicle wheel is acted upon by brake pressure and the latter is dimensioned so that the result is the initial retardation in accordance with the driver's wish. During this initial test phase of the braking, the absolute brake slip .lambda..sub.B as well as the friction utilization .mu..sub.B linked therewith is continuously determined as soon as, as a result of just the braking of the test wheel, the vehicle retardation z increases no further and/or the braked vehicle wheel is more strongly retarded than corresponds to a predetermined threshold value, the test braking is interrupted and the braking is continued by pressure action on the further vehicle wheels; corresponding test braking phases are carried out in cyclic sequence for all guidance wheels.

The present invention discloses preadhered, melt-spun, spin-drawn polyester filaments having improved adhesive properties towards rubber and processes for making the same. The process for making these filaments include the following steps:(a) spin-drawing polyester filaments at an up-take speed ranging between about 2,000 and about 6,000 meters per minute by using an integrated spin-drawing process; and(b) immediately after spin-drawing, applying to the polyester filament a composition which has simultaneously about 0.05 to about 0.5% by weight of a polyepoxide and about 5 to about 140 ppm of a tertiary amine with linear functional groups.The resulting polyester filament has a minimum adherence towards rubber in the Strip-test of about 16.0 to about 21.5 daN.

A control system for a vehicle has a detection device for generating signals which describe the operating and vehicle state. The latter signals are supplied to a regulating and control unit which generates actuating signals for switching on and off a vehicle component that influences a brake servo device for automatically producing braking force if the accelerator pedal is not actuated by the driver. This “acceleration—automatic braking” mode is triggered if the brake pedal has been actuated in a prescribed manner within a defined period of time.

A device for winding webs of fabric into a lap, arranged on a lap rod, with a machine frame, a lap carrier which can move to and from with respect to the machine frame between a winding position and an unloading position and is provided with receiving mechanism for the two ends of the lap rod, which have positioning guides which position the lap rod in the winding position of the lap carrier in a winding rotational position, and with securing elements which secure the lap rod, in the winding position of the lap carrier, against any movement out the positioning guides.
摘要:
In order to avoid faults as a result of different diameters of tires, under prescribed conditions a correction of one wheel speed with respect to the other on each side of the vehicle is performed. The conditions are based on a comparison of the throttle valve angle to the zero torque angle, and a comparison of the speed of the driven wheel to the speed of the non-driven wheel.

A device for data transmission for a motor vehicle is presented, which has sensors used for generating data. The sensors are arranged on or in chassis components occupying a variable position relative to the body of the motor vehicle. Furthermore, the device for data transmission has components or assembly units provided as rigid parts of the body for processing and/or evaluating the data generated in or on the chassis components occupying a variable position and a means for transmitting the data supplied by the sensors to said components, which are arranged as rigid parts of the body. The transmission means is designed according to the present invention as a plastic film web, which is provided with strip conductors and whose strip conductors establish a connection between interfaces provided on the chassis side and on the body side.
摘要:
A method and apparatus for braking a vehicle having a vehicle brake system with a brake control device, and an engine whose torque is transmitted via a transmission to driven wheels. When there is a malfunction of the braking system and a demand for a braking operation, the transmission ratio is increased by a transmission control unit, which activates the transmission, to produce increased braking torque at the driven wheels.
