Definitions
- the invention is based on a housing block of an anti-lock device of a hydraulic motor vehicle brake system according to the preamble of claim 1 and on a method for its production according to the preamble of claim 7.
- an anti-lock device with such a housing block which has numerous recesses, bores, receiving holes and the like for receiving an eccentric, directional control valves, two pump pistons and first and second storage chambers.
- further bores and channels are provided in order to create hydraulic or electrical connections between the components arranged in or on the housing block, such as an electric motor.
- a common feature of these bores, channels, recesses and receiving holes is thus that they are exclusively for the function of Blok- kierschutzein ⁇ 'rect provided.
- the housing block separate clamping bores on the top and bottom, which are provided for receiving clamping tools and which are manufactured in a first machining step. The housing block can then be clamped for further machining steps, for example in a machining center, by means of clamping tools inserted into the separate clamping bores.
- each receiving hole or each channel can be designed as a clamping hole, especially since there are usually holes, receiving holes and channels of different dimensions and diameters in the housing blocks of anti-lock devices.
- the engagement surface is formed by at least one annular bead which is arranged on the radially inner peripheral surface of the function-related bore and which is formed by
- Expanding means of an expanding mandrel inserted into the bore is designed to be able to be gripped behind.
- the spreading means preferably include, in a radially outer position, hydraulically drivable balls which are in a ring groove Spreading head of the expansion dome are held.
- the hydraulically actuated balls that engage behind the annular bead enable a particularly good interlock between the mandrel and the housing block and consequently a high degree of rigidity in the housing block, which has a positive effect on the manufacturing accuracy.
- the function-related hole can be a blind hole or a through hole, depending on where the respective hole is located on the housing block.
- bores are preferred as clamping bores, which are as close as possible to the machining points of subsequent machining steps in order to avoid large lever arms between the clamping point and the cutting force acting on the machining point. Such large lever arms would lead to undesirable displacements of the housing block, which would have an adverse effect on the manufacturing accuracy.
- the function-related bore comprises at least one through hole which is provided for the implementation of an electrical contact and / or an electrical line, which and / or which has an electrically conductive connection between an electric motor and an electronic control device arranged on the opposite side of the housing block creates. Due to its diameter, this through hole is particularly suitable for holding mandrels.
- FIG. 1 shows a perspective view of a preferred embodiment of the invention
- FIG. 2 shows a sectional view along the line II-II of FIG. 1;
- FIG 3 shows an expanding mandrel which engages in a form-fitting manner in a through bore of the housing block.
- FIG. 1 A preferred embodiment of a housing block 1 according to the invention of an anti-lock device of a hydraulic motor vehicle brake system is shown in a perspective view according to FIG.
- the housing block 1 includes, in addition to other channels and bores, such as a stepped eccentric bore 2 for receiving an eccentric driven by a motor shaft of an electric motor (not shown for scale reasons), bores 4 for wheel connections and bores 6 for master cylinder connections, one that is best visible in FIG. 2, for example cylin - Drical through hole 8, which is provided for performing an electrical contact and / or an electrical line.
- the electrical contact and / or the electrical line creates an electrically conductive connection between the electric motor and an electronic control device arranged on the opposite side of the housing block 1. Since the through hole 8 thereby has a function within the anti-lock device, 5 it is a function-related through hole.
- a through hole provided for such a function is known for example from WO 01/26945 A1.
- the through hole 8 is preferably arranged parallel and in the immediate vicinity of the eccentric bore 2.
- a central axis of a further, I O preferably formed as a blind hole 10, which exclusively as
- Clamping hole is used, for example, in the same plane as the central axes of the eccentric bore 2 and the through hole 8, the blind hole 10 being beyond the eccentric bore 2 in relation to the latter.
- the through-hole 8 additionally serves as a clamping hole for clamping devices of one or more machine tools, with the aid of which the housing block 1 is processed, for example for the positive reception of clamping devices of a machining center.
- both holes 8, 10 have engagement surfaces for the clamping means, which are spaced, for example, by equidistantly from the housing surface 12 facing the electric motor, each on the radially inner circumferential surface of the respective hole 8 , 10 arranged, circumferential ring desert 14 are formed, which are arranged perpendicular to the central axis of the respective bore 8, 10.
- the through hole 8 and the blind hole 10 are also manufactured as stepped bores, with their diameter gradually decreasing in a direction pointing away from the housing surface 12.
- the two holes 8, 10 serve for the positive reception of expanding mandrels 16, which are fastened, for example, to a clamping device of the machining center, which is not shown for reasons of scale.
- the expanding mandrel 16 has an expanding head 18 with expanding means which releasably engage behind the annular bead 14.
- the spreading means are preferably formed by a circumferential annular groove 20 of the spreading head 18 movable ⁇ held and distributed there over the periphery are arranged balls 22 which engage behind by the action of a pressurized hydraulic fluid radially outwards, in a the annular bead 14 of the through hole 8 position are pushable, as shown in Fig.3.
- the expanding mandrel 16 is positively fixed in the through hole.
- the through hole 8 and the blind hole 10 are first produced in one setting, for example by drilling, internal turning or circular milling.
- the housing block 1 is tensioned as described above by the two expanding mandrels 16 anchored in the holes 8, 10 and the further bores, channels and receiving holes 2, 4, 6 are made.
- a plurality of such bores can also be formed as clamping bores.
