Fastening for a rail and arrangement for fastening of rails The invention relates to a fastening for a rail for securing a rail (10) whose foot is resting on a concrete sleeper (16), comprising at least one elastic clip (20) having several legs of which at least one leg extends inside a shoulder (42, 44) or channel of a holder (24) that is connected to the concrete sleeper, and at least one further leg rests on the rail foot. For securing a rail to the necessary extent with simple design means and in space-saving form, it is suggested that the holder (24, 26) is arranged detachably in the concrete sleeper (16) or in a plate element resting thereon and is connected to the concrete sleeper by a bolt element.

Described is a method of controlling a power distribution hydromechanical branched transmission consisting of an adjustable hydrostatic unit (4), an integrating planetary gear (10) with at least two outputs (26, 27) and, connected to the integrating planetary gear, a range-changing gear (11) designed as a double planetary gear. The two outputs (26, 27) are connected to the range-changing gear (11) by a first clutch (K1) or a second clutch (K2), and one element of the range-changing gear (11) is controlled by a third clutch (KV). Additional clutches (K3, K4) are fitted for the other ranges. In conditions in which the gear-change position is uncertain, the first clutch (K1) or the second clutch (K2), depending on the instantaneous speed of the vehicle, is synchronized and engaged by adjusting the hydrostatic unit (4), and then either one of the other clutches (K3, K4) or the third clutch (KV) is synchronized and engaged.
摘要:
The seat cushion of a seat can be tilted about its longitudinal center axis for generating a tilting movement of the pelvis of a seat occupant. For generating the tilting movement, an adjusting element is provided in each of the right and the left area of the seat cushion. The adjusting elements interact to cause an opposite adjusting movement in the vertical direction, whereby the tilting movement of the pelvis is achieved. The adjusting elements are constructed, for example, as liquid-filled rolling bellows, in which case a sliding vane rotary pump changes the volume of the two adjusting elements in a diametrically opposed manner.

A rail fastening apparatus fastens an inner stock rail in a railway slide chair assembly. The apparatus includes a base plate. The base plate has on one face a rail seat region on which the inner stock rail sits when the slide chair assembly is in use. A resilient rail fastening clip restrains the inner stock rail. A locating means locates the rail fastening clip in a first position. A loading means vertically deflects the clip so as to produce a load in a toe portion of the clip. A second locating means holds the rail fastening clip in a second position different from the first position such that the toe portion of the clip sits on a ramp of the loading means in a preload condition in which the clip does not bear on the rail

A rail fastening apparatus for fastening an inner stock rail (2) in a railway slide chair assembly comprises a baseplate (100) having on one face thereof a rail seat region (110) on which the inner stock rail (2) sits when the slide chair assembly is in use, a resilient rail fastening clip (7) for restraining such an inner stock rail (2), the clip (7) comprising an elongate member having at one end a toe portion (71) for bearing on the rail (2), locating means (101, 102) for locating the rail fastening clip (7), which locating means (101, 102) are positioned on the baseplate (100) in a second region (120) spaced from the rail seat region (110), the clip (7) having at its other end a heel portion (72) for engaging the locating, means (101, 102), and the locating means (101, 102) comprising an abutment portion (101a) against which the heel portion (72) of the clip (7) abuts when the apparatus is in use to inhibit withdrawal of the clip (7) from the rail (2), and loading means (9) for vertically deflecting the clip (7) so as to produce a load in the toe portion (71). The abutment portion (101a) of the locating means (101, 102) comprises a wall (101a) of a recess (101) provided on the face of the baseplate (100) and the loading means (9) comprise a ramp (9) provided adjacent to the rail seat region (110), whereby the clip (7) can be installed in the apparatus by hammer-driving the heel portion (72) of the clip (7) towards the rail seat region (110) until the toe portion (71) slides up the ramp (9) onto the rail (2) and the heel portion (72) drops into the said recess (101).
