An integration element including a shaft and a housing, wherein the housing includes a passage for the shaft and the shaft includes connecting elements on the shaft ends which are accessible from outside the housing, these elements providing a rotationally-fixed connection to connecting shafts. The housing has at least one connection for fastening to a connection structure and the shaft together with the housing delimits a measuring equipment space for receiving measuring equipment. The housing is formed by at least two housing parts detachably connected to each other, said housing parts being designed to be separated around the full extent of their circumference surrounding the shaft to allow access to the measuring equipment space. The housing has bearing seats for shaft bearings and these shaft bearings support the shaft in a rotatable manner with respect to the housing.

The invention relates to a device for adjusting the height of a vehicle body, having two components, which can be moved longitudinally relative to each other, and a movement thread, which is arranged between these components. The movement thread includes a partial thread which is designed as a spindle paired with a first component and a partial thread which is designed as a spindle nut paired with the other component. The partial threads are designed to be axially movable relative to each other by a rotational drive. The device also includes a locking device which bridges the movement thread in at least three longitudinal positions and which comprises an axially fixed locking ring that is arranged on the spindle in a rotatable manner and has locking cams distributed over the circumference and a shifting gate that is rigidly connected to the spindle nut in an axial manner, receives the locking cams, and includes locking stops, which are arranged at end positions of the at least three longitudinal positions and are distributed over the circumference, and switching ramps, which lie axially opposite the locking stops, are provided with slopes that decrease in the circumferential direction, and are arranged over the circumference. A movement of the locking cams towards the locking stops and towards the switching ramps in the shifting gate is provided by an axial movement of the spindle relative to the spindle nut, this displacement depending on a rotational direction of the rotational drive, and a selection of the locking stops is carried out by rotating the locking ring by the rotated locking cams resting against switching stops provided between the switching ramps. In order to shorten the switching paths and the switching times of the locking device, at least one switching ramp arranged between two locking stops is expanded relative to the remaining switching ramps in a direction of the locking stops.
