Definitions
- the present invention relates to an adapter component and an adapter assembly for connecting a brake booster to a mounting bracket of a vehicle, a brake booster assembly, a method for producing an adapter component and a method for assembling a brake booster assembly.
- Brake boosters such as electromechanical brake boosters, are designed to amplify the force generated by a brake pedal or brake lever, or to generate an output force based on travel of the brake pedal or brake lever. This is usually done by means of an electric servo drive, which is kinematically coupled to an actuating rod via a gear.
- the brake booster is attached to a mounting bracket in the vehicle, for example to a wall section.
- fastening openings are usually formed on the mounting bracket, in which fastening pins provided on the brake booster are fixed. Consequently, it is necessary to change the location of the mounting pins on the brake booster and to match the location of the mounting holes of the receiving bracket.
- an adapter component for connecting a brake booster to a mounting bracket of a vehicle with the features of claim 1, an adapter assembly with the features of claim 9, a brake booster assembly with the features of claim 11, a method for producing an adapter component with the features of claim 12 and a method of assembling a brake booster assembly having the features of claim 13 is provided.
- an adapter component for connecting a brake booster to a mounting bracket of a vehicle includes a flat extending base part, which has at least two first connection openings for receiving first connecting pins for fastening the brake booster, a collar, which runs in a direction transverse to the base part axial direction projecting from the base part, and a flange projecting outwardly from the collar in a radial direction, which flange has at least two second connection openings for receiving second connection pins for attachment to the receiving holder.
- a method for producing an adapter component according to the first aspect of the invention includes forming the base part, the collar and the flange by deep drawing a sheet metal blank, creating the first connection openings in the base part and creating the second connection openings in the flange.
- a method of assembling a brake booster assembly according to the third aspect of the invention. This method includes fixing the second connection pins in the second connection openings of the flange of the adapter component and fixing the first connection pins in the first connection openings of the base part of the adapter component.
- the adapter component being implemented as a substantially hat-shaped, thin-walled component.
- the adapter component can be implemented, for example, as a shaped sheet metal, which can have a thickness in a range between 2 mm and 4 mm, for example.
- the adapter component has a base part or a base plate with a first surface and a second surface located opposite thereto, a collar or axial web which projects from the first surface in an axial direction transverse to the first surface, and a flange or radial web.
- the flange extends from an end of the collar that is in relation to the axial direction is located away from the base part, in a radial direction, ie transversely to the collar, outwards, in particular with respect to a geometric center of the base part.
- the base part has a plurality of first through-openings or connecting openings, into which connecting pins provided on the brake booster can be inserted.
- the flange also includes a plurality of second connection openings which are arranged in a pattern which corresponds to a hole pattern of the receiving bracket.
- the second connection openings in the flange can easily be arranged at distances from one another which differ from the distances between the first connection openings in the base part. Another advantage is that the adapter component can be manufactured extremely cheaply, e.g. by deep drawing.
- the base part has a central recess for passing through an actuating device of the brake booster.
- the central recess may be arranged coaxially to the geometric center of the base part, with the first connection openings being located between a peripheral edge of the base part and the central recess with respect to the radial direction.
- the base part has an essentially circular outer circumference.
- the geometric can be defined, for example, by the center of the circle that corresponds to the outer circumference.
- the geometric center can be defined, for example, by the centroid of the base part, in particular the first surface of the base part.
- the first connection openings are arranged inside the collar with respect to the radial direction.
- the first connection openings are arranged between the geometric center of the base part and the collar.
- the collar is designed as a closed, peripheral frame.
- the collar can be ring-shaped or essentially ring-shaped.
- a circumferential collar offers the advantage that it can be easily produced using a deep-drawing process.
- the rigidity of the adapter component can be increased further as a result.
- the collar is arranged in an edge area of the base part with respect to the radial direction.
- the collar can be designed as a fold over the base part or can extend from the outer circumference of the base part. Such a design is easy to produce in a deep-drawing process.
- a number of the second connection openings is different from a number of the first connection openings. This advantageously increases the possible uses of the adapter for different hole patterns on the mounting bracket and the brake booster.
- the fixing of the first connecting pins in the first connecting openings of the base part of the adapter component includes passing the first connecting pins through the first connecting openings and screwing a nut onto each first connecting pin.

- the collar 2 can in particular be implemented as a web connected to the base part 1 . As shown by way of example in FIG. 2, the collar 2 extends along the axial direction A1 and thus transversely to the base part 1. In particular, the collar 2 protrudes from the first surface 1a of the base part 1 in the axial direction A1.
- the collar 2 can optionally be designed as a peripheral frame. As shown by way of example in FIG. 2, the collar 2 can be implemented as an essentially ring-shaped frame. "Substantially annular" includes both a continuous ring and a ring shape that has a plurality of ring or cylinder segments separated by intermediate sections that have a common center point, as shown in FIG. 2 by way of example. Provision can also optionally be made for the collar 2 to be arranged in an edge region of the base part 1 in relation to the radial direction RI.

- the second connecting pins 231 can, for example, be fixed in the respective receiving recess 511 by nuts 232 which are screwed to an external thread of the second connecting pin 231 .
- An advantage of the design of the adapter component described is that a modular approach can be implemented in a simple manner, in which the position of the first and the second connection openings 11, 31 and the length of the connecting pins 211, 231 can be adapted relatively easily for different installation boundary conditions, the geometry of the base part 1, the collar 2 and the flange 3 being able to remain unchanged. Only the position of the connection openings 11, 31 has to be adjusted.
