Abstract

An actuator arrangement for a brake, particularly an electric parking brake or an electro-mechanic operating brake with a brake pad-adjustment unit that can be driven by an actuator arrangement. The actuator arrangement comprises: an electric motor, a transmission unit located in a housing, which is coupled to the electric motor and is effectively connected at the output side with the brake pad, adjustment unit, a mechanism for fastening the actuator arrangement at the caliper or at the brake pad, adjustment unit, a plug accept for a connection plug of an electric connection unit, which is electrically connected to the electric motor, the electric motor is encompassed at least partially by an encasement, at which the plug accept is formed in one piece, and/or the fastening mechanism are embodied as a separate exchange part, with fastening openings, and fixed at the actuator arrangement in a torque-proof fashion.

First claim

We claim:

1. An actuator arrangement for a brake, particularly an electric parking brake or an electro-mechanic operating brake with a brake pad-adjustment unit, which is driven by an actuator arrangement, with the actuator arrangement assembled in a modular fashion and showing the following features:
an actuator,
an electric motor,
a transmission unit located in a housing, which is coupled to the electric motor and at the output side is effectively connected to the brake pad-adjustment unit,
fastening means embodied as a separate exchange part for fastening the actuator arrangement at the caliper or the brake pad-adjustment unit, and
a plug accept or a connection plug of an electric connection unit, which is electrically connected to the electric motor,

and wherein:
the electric motor is at least partially encompassed by an encasement, at which the plug accept is formed in one piece for the connection plug, and
the fastening means is embodied as an attachment part and sits on the actuator, wherein such fastening means is fixed at the latching cams of a transmission carrier cup and the latching cams of a housing lid of the actuator arrangement.

2. The actuator arrangement of claim 1 , wherein the encasement is made from plastic and embodied as a cylindrical plastic cup, in which the electric motor is accepted within a motor housing, with the plug accept extending in one piece from a cylindrical wall of the plastic cup.

3. The actuator arrangement of claim 1 , further comprising wherein an entire electric contacting of a drive unit is arranged in the encasement.

4. The actuator arrangement of claim 1 , wherein a transmission carrier cup is made from plastic and, fixed at a joined connection at the bottom of the transmission carrier cup, with the encasement accepting the electric motor, particularly by a material-to-material connection, such as ultrasound welding, laser welding, or adhesion.

5. The actuator arrangement of claim 1 , wherein the fastening means are embodied as a metallic stamped part or a plastic part.
