摘要:
An anti-lock hydraulic brake system comprising a separating valve (14) and a regulating valve (19). A combined arrangement is provided wherein the valves are connected into each other. The movability (play s) of the piston (30) affords the event that a compensating volume for the control action in the event that the output of the pump is insufficient in specific situations requiring a large amount of fluid for control.
摘要:
An anti-lock hydraulic brake system is described wherein a throttle valve has a restrictive flow condition which becomes effective in the brake line in the event of brake slip control. Pumps for reapply pressure deliver fluid to the wheel brake via this restriction and regulating the pressure in the wheel brake is performed by control of an outlet valve. The throttle valve is operated hydraulically by various arrangements including the application of pump pressure, or by wheel brake pressure applied upon opening of the outlet valve at the start of an anti-lock control cycle.

A hydraulic anti-locking brake unit is presented in which the brake line is shut off by an isolating valve (20) during a control action. For the reduction of the pressure, the outlet valve (7) is opened, so that the pump (14) delivers hydraulic fluid out of the wheel brake into the high-pressure accumulator (19). For a renewed pressure build up, the inlet valve (6) is opened, so that hydraulic fluid flow is directed out of the high-pressure accumulator (19) back to the wheel brake. In order to be able to utilize a high-pressure accumulator having a low receiving capacity, various valving arrangements are disclosed to direct excess flow from the pump either to the master cylinder or a low pressure accumulator.

An assembly, consisting of a motor and a pump, the motor being arranged in a motor housing and the pump in a pump housing. Both housings can be coupled to each other. The motor housing is provided with a second main bearing. The pump housing is equipped with a pump bearing. During normal operation, the forces acting on the pump eccentric are essentially supported by the main bearing and the pump bearing. The bearing forces are introduced into the pump housing. If the motor housing is not fastened to the pump housing, the rotor shaft is supported by the main bearing and, if necessary, an accessory bearing. Thus the motor can be tested without being connected to the pump housing.

The invention relates to a motor-driven pump unit, in particular for antilock systems of motor vehicles, with an electric motor that is arranged on one side of a pump unit and an electronic unit that is arranged on another side of the pump unit and fastened thereto. The main aspect of the invention is that means are provided for an axially movable attachment and contacting of carbon brushes in connection with an axial installation of the unit. In this way, the individual components of the unit can be assembled axially in a simple manner and at low cost. In addition, the unit requires very little space.

An electrohydraulic pressure control mechanism, with electromagnetically controllable hydraulic valves arrayed on a valve housing, with coils which have some of their parts overhanging the valve housing, and the parts being equipped with contact elements. A molding box enclosing the coils and the contact elements, with the molding box or part thereof being suitable for installation of an electronic controller or parts of terminals for such. The molding box featuring cavities extending from its set-down surface on the valve housing to the far outer surface of the molding box; and the cavities taking on the form of lead-through opening in the proximity of coils. This assures a simplified attachment of coil casings to the valve domes.

A motor-and-pump assembly includes armature shaft of the electric motor which is retained in the pump housing by way of a main bearing and an auxiliary bearing.The objective is to align the motor housing centrically to the axis of the armature and, in addition, to achieve a reliable attachment of the motor housing to the pump housing.Therefore, the housing of the electric motor has a bowl-shaped design, and the rim of the motor housing is inserted into a concentrically circumferential groove in a flange surface on the pump housing. The diameter of the inner wall of the groove corresponds to the inside diameter of the motor housing. Thus, the inside wall of the motor housing abuts on the inner rim of the groove. The motor housing is thereby aligned centrically.The motor housing can simply be fastened to the pump housing by a clamping ring which is also inserted into the groove.
