Abstract: An electric caliper includes an electric drive mechanism which generates a pressing force for pressing a friction pad against a disc rotor, and a retraction mechanism provided in a piston of a pressing mechanism. The mechanism includes a reversing member which is compressed by a force transmission portion and a pressing portion of the piston to thereby generate a reverse force. Also, the mechanism includes a movable element which relatively retracts due to the reverse force, and a first elastic member which is compressed by the movable element and the advancing force transmission portion to thereby apply a restoring force. Thus, in the mechanism, the reversing member generates the reverse force as a result of advancement of the force transmission portion, and the movable element relatively retracts due to the reverse force and compresses the first elastic member.

Abstract: A stabilizer serves for stabilizing a link of a three-point suspension system of an agricultural tractor. The stabilizer has at least one telescope consisting of a tube and a piston held displaceably therein. Said tube and piston are coupled elastically by at least one spring. The piston is designed such that it can be adjusted in length by means of at least one thread. In order to retain the telescope, the stabilizer has at least one pivotably held retaining clip. In a retaining position, said retaining clip engages over an abutment of the piston whereas, in a release position of the retaining clip, the piston can be freely moved. In order to obtain simple handleability of said stabilizer, the abutment is formed by at least one substantially rotationally symmetrical disc. The piston length can therefore be adjusted in or in the vicinity of the retaining position.
