Embodiment Construction

[0009] The hydraulic block 1 according to the invention shown in the drawing is produced from metal using a 3D printer, i.e. layer by layer, wherein the hydraulic block 1 is not a layer composite, but a composite of successively applied coatings homogeneous body. The 3D printing methods used are, for example, selective laser melting, selective laser sintering or electron beam melting. The hydraulic block 1 is square, and in appearance, it is rectangular, approximately square, and its height is about 1 / 4 of its width or length. 3D printing can also be understood as a shapeless (such as liquid, paste, etc.) , granular, powdered, chipped or fibrous) metal that solidifies, connects and / or hardens into a solid hydraulic block 1 .

[0010] The hydraulic block 1 has receptacles for hydraulic components of a brake adjustment system of a hydraulic vehicle brake system. Such components are, for example, hydraulic pumps, solenoid valves, non-return valves, pressure sensors, hydraulic a...

Abstract

A hydraulic block (1) 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 (1) is manufactured by 3D printing, which enables considerably more complex line routing than manufacture by machining.

Description

technical field [0001] The invention relates to a hydraulic block for a hydraulic assembly of a brake adjustment system of a hydraulic brake system of a vehicle having the features stated in the preamble of claim 1 . Background technique [0002] Such hydraulic blocks are known. Generally speaking, it is a square, approximately square block of metal in appearance, and the height is about 1 / 4 to 1 / 3 of the length or width. The hydraulic block has a receptacle for hydraulic components of the brake adjustment system and lines for coupling and / or connecting the receptacle or components installed in the receptacle. The hydraulic components of the brake regulating system of the hydraulic vehicle brake system are, for example, solenoid valves, non-return valves, throttle valves, hydraulic accumulators, shock absorbers and pumps. Generally speaking, the receptacle is a cylindrical blind hole with a stepped diameter. The lines in the hydraulic block are connected to the receptacle...
