Abstract
A unit comprising a drive motor and a radial piston pump is proposed, in which unit an armature of the drive motor and an eccentric of the radial piston pup are carried by a common unitary shaft which has three bearings. A three-bearing mounting, known from the prior art, for a shaft of this kind consists of three ball bearings, which are expensive. The invention proposes to replace the ball bearing situated at the greatest distance from the eccentric in the prior art by a slide bearing, and to design the latter as a sintered metal bearing and to impregnate it with a viscous lubricant. The unit according to the invention can be used as a component of an anti-lock device of a vehicle brake installation or of a drive-slip control device acting on driven wheels.
