HYDRAULIC UNIT, MORE PARTICULARLY FOR THE OPEN-LOOP AND CLOSED-LOOP CONTROL OF BRAKE PRESSURE IN A BRAKE CIRCUIT OF AN ELECTRONICALLY SLIP-CONTROLLABLE BRAKING SYSTEM OF A MOTOR VEHICLE AND METHOD FOR ASSEMBLING A HYDRAULIC UNIT

The invention relates to a hydraulic unit (10), more particularly for the open-loop and closed-loop control of brake pressure in a brake circuit of an electronically slip-controllable braking system of a motor vehicle and to a method for assembling a hydraulic unit (10). Known hydraulic units (10) have a pump housing (12), a motor (17) for driving a brake pressure generator (19), and an electronic control device (20) for controlling the motor (17) in line with demand. The motor (17) and the control device (20) are disposed on opposite sides of the pump housing (12), and a shaft bore (14) extending all the way through is formed therebetween, in which shaft bore a motor shaft (18) which can be rotationally driven is disposed. A sealing apparatus seals the shaft bore (14) with respect to an interior of the electronic control device (20). A sealing apparatus which comprises an insertion seal (50) disposed on the pump housing (12) in a seal socket (52) and to which a mechanical preloading force is applied by a preloading apparatus (48) is proposed. Unidad hidráulica, en particular para el control de lazo abierto y lazo cerrado de una presión de frenado en un circuito de frenado de un sistema de frenado electrónicamente regulable por deslizamiento de un vehículo de motor y método de montaje de una unidad hidráulica.
