Hydraulic block for a hydraulic unit of a brake controller of a hydraulic vehicle brake system
A hydraulic block for a hydraulic unit of a brake controller of a hydraulic vehicle brake system is configured to fit with hydraulic components such as solenoid valves of the brake controller. The hydraulic block is manufactured by 3D printing, which enables considerably more complex line routing than manufacture by machining.
1. A hydraulic block for a hydraulic unit of a brake controller of a hydraulic vehicle brake system, comprising:
a hydraulic block body formed as a homogeneous single piece structure;
a plurality of receptacles defined in the hydraulic block body and configured for hydraulic components of the brake controller; and
a plurality of lines defined in the hydraulic block body and configured to at least one of (i) port the hydraulic components and (ii) connect the hydraulic components,
wherein the hydraulic block is formed by casting, die casting, sintering, or 3D printing,
wherein at least one line of the plurality of lines includes a straight portion having a central axis that runs in an axial direction of the straight portion of the at least one line, and
wherein linear extensions of the central axis of the straight portion pass, in both directions along the axial direction, through portions of the homogeneous single piece structure of the hydraulic block body.
2. The hydraulic block according to claim 1 , wherein the hydraulic block is formed by 3D printing.
3. The hydraulic block according to claim 1 , wherein one or more of the plurality of lines is a stub line.
4. The hydraulic block according to claim 1 , wherein:
the plurality of lines further include at least one of:
first mouths located at intersections of the plurality of lines, the first mouths having first edges; and
second mouths located at openings of the plurality of lines into the plurality of receptacles, the second mouths having second edges; and
at least one of the first mouths and the second mouths includes chamfers or curves.
5. The hydraulic block according to claim 1 , wherein at least one of the plurality of receptacles has a non-circular cross-section.
6. The hydraulic block according to claim 1 , wherein:
one or more of the plurality of lines includes a first portion having a first central axis and a second portion having a second central axis;
the first central axis and the second central axis intersect so as to define an angle.
7. The hydraulic block according to claim 1 , wherein one or more of the plurality of lines includes at least one curved portion, the at least one curved portion having a central axis that is curved.
