Patent ID: 7383927

Claim:
An operating mechanism for a parking brake having brake cables and arranged in a housing, the operating mechanism comprising: a motor rigidly installed in the housing; a threaded rod; a coupling element connecting the threaded rod to the motor, wherein the threaded rod is axially displaceably arranged in the coupling element; a first brake cable fixing guided on the threaded rod and adapted to transform rotation of the motor to a linear movement of the first brake cable fixing; a second brake cable fixing arranged axially with the first brake cable fixing, wherein rotation of the motor causes relative movement of the first brake cable fixing with respect to the second brake cable fixing; wherein the first brake cable fixing and the second brake cable fixing are adapted to carry out a common movement relative to the housing, thereby to uniformly distribute a load to the brake cables connected thereto; wherein the first brake cable fixing and the second brake cable fixing are arranged on the threaded rod and adapted to execute a common movement relative to the motor; and wherein the coupling element provides a direct positive connection between the motor and the threaded rod, such that the first brake cable fixing, the second brake cable fixing, the threaded rod, the coupling element, and the motor are positioned along a common axis.
