A brake disc has an outer friction path on one side and an inner friction path on the other side. Between the friction paths free spaces are provided, which on the outer friction path side have a different configuration than on the inner friction path side.

A brake actuator for an electrical parking brake comprises an electric motor and a planetary gear set. The axes on which the planet wheels are carried on the planet carrier are joined substance-to-substance to the planet carrier, i.e. formed in one piece with it or for instance mounted on its surface by means of atomic or molecular forces. Recesses on the axes can receive a lubricant. Spacers between the planet carrier and planet wheels can reduce the contact surface in the axial direction.

An assembly ( ) for use in a vehicle suspension system for connection with a wheel ( ) of a vehicle includes first and second hollow hydroformed sections ( and ). In one embodiment of the assembly ( ), upper and lower pivot mountings ( and ) are connected with the hollow hydroformed sections ( ). A wheel mounting section ( ) is pivotally connected with the upper and lower pivot mountings ( and ). The pivot mountings ( ) allow the steerable vehicle wheel ( ) to be turned to effect steering of a vehicle ( ). The assembly ( ) may be utilized in association with a vehicle wheel ( ) which is not steerable. When the assembly is utilized in the vehicle wheel ( ) which is not steerable, the pivotal wheel mounting section ( ) may be eliminated.

An axle journal (20), especially for the front axle of a front wheel drive motor vehicle comprises a main body (30) made of shaped sheet metal parts (32, 34) which enclose a circumferentially extending cavity (36). The cavity (36) houses portions (43) and (46) of mounting components (brake carrier member 42 and a combination 45 steering tie rod mount and transverse link seat) which portions stiffen the axle journal (20). The section of the cavity not taken up by the stiffening portions of the mounting components may be foam-filled. This composite-structure axle journal can be manufactured at low cost due to the reduced mechanical finishing required and can sustain heavy loads, whereby it meets present day requirements of lightweight construction.

An electronically controllable braking system for ground vehicles, comprising a cylinder/piston arrangement (6) which is able to introduce friction forces (F.sub.akt) into a friction element (8) which is coupled with a vehicle wheel by subjecting a hydraulic chamber (4) of the cylinder/piston arrangement (6) with hydraulic fluid, is developed further in that an electrically actuatable displacement element (12) projects into the hydraulic chamber (4) of the cylinder/piston arrangement (6) which is actuatable as a function of control signals from an electronic controller (22) for increasing or decreasing the pressure acting on the hydraulic fluid in the hydraulic chamber (4) in order to increase or decrease, respectively, the friction forces (F.sub.akt) which, during a braking operation, are introduced into the friction element (8).

An apparatus for shaping a three-dimensional workpiece by inducing the following relative motions between an abrading die member and the workpiece: a feed motion, periodical retract and advance motions in a z-direction, and a planetary or orbital motion in the x and y directions. The mechanism which generates the planetary or orbital motion is provided with means for infinitely adjusting the eccentricity of this motion and is provided with means for selectively and releasably fixing the chosen amount of eccentricity. An assembly is provided to adapt the following process values to conditions within a gap between the die and the workpiece such that the abrading process is optimized: (i) feed pressure between the die and the workpiece during an abrading period of a work cycle; (ii) speed of the feed motion; and (iii) speeds of periodical retract and advance motions.
