linjaer vaexel saerskilt at transfervagn in parking garage

摘要

Linear gearing primarily intended for use in connection with so-called transfer trolleys in automatic parking buildings. The transfer trolley includes a first carriage (101) which can be moved in at least a horizontal direction, and a second carriage (102) which is connected to the first carriage for movement from a first end position, in which the second carriage is located within the horizontal extensions of the first carriage, to a second position in which the second carriage has been moved in its longitudinal direction and the longitudinal direction of the first carriage and is located completely outside, or substantially completely outside the horizontal extensions of the first carriage. The invention is characterized in that the linear gearing includes at least two chains, namely a first chain (17A) which runs between two end wheels (16A, 16B) between which a first rod (11) or the like extends, and a second chain (17B) which also runs between two end wheels (16C, 16D) between which a second rod (19) or the like extends, the chains being in mutually spaced, parallel relationship. The first rod (11) is connected to a power source (103) which functions to move the rod (11) in the direction of its longitudinal axis relative to the first carriage (101), and the run or part of the second chain (17B) which is remote from the first chain (17A) is connected to said second carriage (102). The second rod (19) is connected to that run of the first chain (17A) which lies adjacent the run of the second chain (17B), and the run of the second chain (17B) which lies adjacent the run of the first chain (17A) is attached to the first rod (11). The run of the first chain (17A) which is remote from the run of the second chain (17B) is attached to the first carriage (101).
