Abstract
A pressure modulator for an ABS system includes a housing that which has a hydraulic inlet and a hydraulic outlet that are interconnected via a hydraulic line; a volume accumulator that increases a volume of the hydraulic line during an activated anti-lock function, a linear drive for opening the volume accumulator and an electronic circuit that controls the linear drive and is disposed in the housing.
Claims14
A pressure modulator for an antilock braking system (ABS), comprising:
- a housing having a hydraulic inlet and a hydraulic outlet that are interconnected via a hydraulic line;
- a volume accumulator for increasing a volume of the hydraulic line during an activated anti-lock function;
- a linear drive for opening the volume accumulator;
- an electronic circuit disposed in the housing for controlling the linear drive;
- a spring element, wherein the linear drive comprises a rotor bar and wherein a displacement movement of the rotor bar effectuates an opening of the volume accumulator against a spring force of the spring element;
- and
- a control piston that extends into the rotor bar, the control piston being fixedly connected to the housing and supporting the spring element.
