    摘要: A drill tool-holder comprises close to its end at least two radial cavities each opening outwardly of the tool-holder and inwardly of its axial bore, and each adapted for housing a ball, or cylinder, the outlet orifices of the cavities being dimensioned so that the ball, or cylinder, may be introduced from the outside into these cavities, but cannot come out thereof towards the inside of the tool-holder axial bore, which tool-holder is characterized by the fact that there is associated therewith a piece made from a hard material (3) whose body (10) has the same form as the cavities and may be housed therein without play, and has on each of its opposite faces a projecting portion (11,12) in the form of a small bar.

    摘要: The present invention is directed toward a drill bit which firstly comprises two locking grooves (1,1') diametrically opposed with respect to each other, and secondly, also diametrically opposed, with respect to each other, a first driving groove (3) and a second driving groove (4) associated with a locking groove (2) by being superimposed thereon. The driving groove (4) is advantageously angularly offset with respect to the associated locking groove (2) so as to have, in the drill bit driving zone, the lateral faces of the two associated grooves almost merged. This permits an extension of the friction zone so as to increase the wear resistance thereof, while the opposite lateral faces or edges of the superimposed grooves defines projecting locking surfaces (7) insuring proper locking of the drill bit.

    摘要: To determine the transverse acceleration of a vehicle, in particular as an input quantity for an electronic vehicle control system such as ABS, TCS, EBV, etc., the output signals of wheel sensors representative of the rotational behavior of the individual vehicle wheels are evaluated. The correction factors representing the differences of the tire tread circumferences of the individual wheels are determined. A short-time correction factor and a long-time correction factor KZ and LZ are produced in each case for the non-driven vehicle wheels. A difference between the long-time correction factor and the short-time correction factor of the respective wheel is determined and evaluated in a filtering and adapting circuit. The quotient KZ/LZ of the short-time correction factor and the long-time correction factor of the respective wheel is calculated, and the difference is produced between the quotients of the left and right non-driven ##EQU1## wheels. The transverse acceleration of the vehicle Q.sub.FZ is the result of the relation

    摘要: The present invention describes a process for a vehicle including an electronic control system, which processes input signals representative of the rotational behavior of the individual wheels, and wherein the differences of the tire tread circumferences of the individual wheels are determined by way of short-time and long-time correction factors. The long-time correction factors LZ.sub.n. are determined from the differences D.sub.R1 between the short-time correction factors KZ.sub.R1 and the long-time correction factors LZ.sub.R1 of the respective wheel by averaging LM.sub.r1 the differences during a predetermined time interval and by evaluating and weighting the average value. For the quick identification of an emergency wheel, every time the vehicle engine is started, the long-time factor LZ.sub.R1 is equalled once to the short-time factor KZ.sub.R1 of the respective wheel, if simultaneously the short-time correction factors of three wheels are approximately equal and the short-time correction factor of the fourth wheel adopts a relatively high value, which is within a predetermined range, for a predetermined time interval or minimum time interval, and if the short-time correction factor of the fourth wheel remains approximately constant during this time interval.

    摘要: For the reduction of disadvantageous effects of engine stall torques on the braking behavior of a vehicle which is equipped with a brake unit having an anti-lock control system, the brake slip of the driven wheels is monitored independently of any actuation of the brake. In the event of a rotational behavior of the driven wheels which is typical of the effect of engine stall torques, in particular in the event of a brake slip at the driven wheels exceeding a limit value, brake pressure existing in the wheel brakes of the driven wheels is maintained constant or reduced, or, if the braking action has not yet commenced, the supply of brake pressure into the wheel brakes of the driven wheels is prevented.
