Problems solved by technology

Due to this linear relationship, although the hydraulic load torque on known hydraulic fluid pumps can be well set by simply adjusting the current strength, such hydraulic fluid pumps are not optimal in all parts of the operating range. Work

Embodiment Construction

[0032] exist figure 1In, as already explained above, it is shown how the solution according to the invention can suitably provide a delivery rate of the delivery device of the hydraulic fluid pump on the vehicle brake system which varies depending on the magnitude of the hydraulic back pressure. At this point, regarding the figure 1 The description can be found in the description above.

[0033] exist figure 2 A hydraulic fluid pump 80 is shown in , its main components include an inlet valve 90, an inlet pipe 100, a cylinder 110 with a piston 120 located therein, a corresponding eccentric gear 130, an outlet pipe 140 and an outlet valve 150 . Here, inlet valve 90 , inlet line 100 and outlet line 140 together with outlet valve 150 are fluidically connected to compression chamber 160 formed by cylinder 110 and piston 120 so that hydraulic fluid (not shown) passes through the piston The movement of 120 in cylinder 110 is sucked into and outputted from compression chamber 160...

Abstract

Disclosed is a hydraulic fluid pump (80) for a motor vehicle brake system, comprising delivery means (110, 120) for delivering hydraulic fluid against a hydraulic counter-pressure prevailing in one part of the vehicle brake system (100, 90). Said hydraulic fluid pump (80) further comprises means (270), preferably an elastomer component in the motor shaft bearing (200, 220), for modifying the volume delivered by the delivery means (110, 120) in accordance with the level of the hydraulic counter-pressure.

Description

technical field [0001] The invention relates to a hydraulic fluid pump for a vehicle braking system comprising delivery means for delivering hydraulic fluid against a hydraulic back pressure present in a part of the vehicle braking system. Furthermore, the invention also relates to a vehicle brake system comprising such a hydraulic fluid pump. Background technique [0002] Hydraulic fluid pumps for vehicle braking systems are known, in which hydraulic fluid pumps are used for conveying hydraulic fluid or brake fluid in the vehicle braking system, in particular for returning brake fluid and / or To actively increase the brake pressure, reciprocating piston pumps are used as delivery devices. These reciprocating piston pumps are also referred to as pump elements. [0003] These pump elements are usually driven by an electric motor with an eccentric mounted on the drive shaft. As an alternative, cam drives or the like can also be used. Depending on the eccentricity of the ecc...
