Abstract
A hydraulic unit is elastically supported by means of elastomer elements, through which bolts pass, on two legs of a mounting bracket that extend perpendicular to one another. The leg of the mounting bracket has recesses, open counter to the mounting direction of the unit, for receiving the elastomer element. With clamping means disposed on the bolt, the elastomer element is axially shortened and pressed against both the recess and side faces, located on either side of the recess, of the leg of the mounting bracket. With the shortened elastomer element, a positive and nonpositive engagement with the leg of the mounting bracket is achieved.
Claims7
An apparatus (10) for elastic mounting of a hydraulic unit (11) of a vehicle brake system in a vehicle, comprising:
- a mounting bracket (12) having first (13) and second (14) legs extending at right angles to one another and on which the unit (11) is supported by means of elastomer elements (17, 18) through which bolts (15, 16) pass, the unit (11) being mountable on the bracket (12) in a direction (45) perpendicular to the first leg (13),
- one of said bolts (15), extending in the mounting direction (45) of the unit (11) and into the hydraulic unit, being associated with the first leg (13),
- the second leg (14) of the mounting bracket (12) having at least one recess (21, 22), open counter to the mounting direction (45), for receiving one of the elastomer element (18) with an axis extending perpendicular to the plane of the second leg (14), said one of the elastomer elements (18) being a hollow-cylindrical elastomer element,
- a second of said bolts extending through said hollow-cylindrical elastomer element and into the hydraulic unit,
- the hollow-cylindrical elastomer element (18) associated with the second leg (14) of the mounting bracket (12) having a reduced-diameter middle portion (40), which is placed in the recess (21, 22) of the second leg (14) of the mounting bracket (12);
- the middle portion (40) of the hollow-cylindrical elastomer element (18) being embraced over more than half its circumference by the second leg (14) of the mounting bracket (12);
- the hollow-cylindrical elastomer element (18) associated with the second leg (14) of the mounting bracket (12) being both radially widened and axially shortened by clamping means (34, 35, 36) disposed on the second of said bolts (16);
- and
- the hollow-cylindrical elastomer element (18) being pressed with its middle portion (40) against the recess (21, 22) and with its end portions (38, 39), adjoining the middle portion (40) on either side, against the two side faces (24, 25), defining the recess (21, 22), of the second leg (14) of the mounting bracket (12).
