Abstract:
PCT No. PCT/SE92/00201 Sec. 371 Date Sep. 24, 1993 Sec. 102(e) Date Sep. 24, 1993 PCT Filed Mar. 31, 1992 PCT Pub. No. WO92/17714 PCT Pub. Date Oct. 15, 1992.An electromechanical brake unit in a housing (1) is provided with a drive sleeve (8) subjected to a torque of a prestressed coil spring (6), a locking spring (16) between the drive sleeve and the housing for permitting rotation of the former in a first direction, and a control sleeve (17), which is rotatable by a control motor (20) in the first direction to open the locking spring and allow the drive sleeve to rotate the same angular distance as the control sleeve. In order to obtain rotary force transmission from the drive sleeve (8) over the locking spring (16), if the control sleeve (17) is not held against rotation, the locking spring has a slightly smaller external rest diameter than the bore in the housing (1), with which it is to cooperate, whereas the control motor (20) is provided with means to hold it against rotation in its rest position, unless the current supply is broken.
