COMBINED VEHICLE BRAKE WITH A BALL SCREW DRIVE

摘要

The invention relates to a combined vehicle brake which has a hydraulically actuable service brake and an electromechanically actuable parking brake device. The present invention is based on the problem of improving the known ball screw drives for use in vehicle brakes, of making simple automated assembly possible, and in addition of opening up the possibility to increase cycle times. In order to solve said problem, it is proposed that a spring element (10) of double helical type which is configured differently in sections is provided, by means being provided in a middle section (22), that is to say in the drive thread turn, which means substantially do not impede the elastically pliable adaptation of the spring element (10) to the helically wound drive thread turn, and wherein a bearing section (24) is additionally provided at at least one end of the spring element (10), which bearing section (24) has an increased transverse rigidity or has it impressed onto it in comparison with the middle section (22).
