Storage device for operating rods

The innovation relates to a storage device for actuating rods of adjusting elements for execution limited pivoting movements, especially for feed-through bores, and guidance of the actuating linkage in a sleeve.

Such arrangements are used, for example, as fixed points on Bowden cables that operate a pivot lever and

In addition to the axial movement, a limited angular movement is carried out. It is known to be transmitted in small Forces and low demands on the transmission accuracy to make the Bowden cable ends elastic, Furthermore, with higher demands on the transmission quality, the end pieces of the control cables were also included Articulated joints provided that can absorb the angular movement. These lead in particular when transferring Compressive forces, however, to high lateral guidance and kinking

forces that also affect the transmission quality.

It is also known to arrange ball joints, with the spherical body is firmly connected to the bearing element and encompassed from the outside by two spherical half-shells as well as is performed, which for example run out like a flange and are screwed to the fixing wall. As a result, all the kinematic requirements for a high-quality storage device are met, but it does a lot of space is required and installation is difficult. This is especially true in the event that the Implementation of the control cable through the storage device and the fixing wall must be made tight, like this when passing through the bulkhead between the crew compartment and the machine room of heavy vehicles is required.

The task of the innovation is to create a simple storage device of the generic type, which allows a small installation space and also ensures tightness requirements.

This object is achieved according to the invention in that concave half-shells are arranged on the sleeve to form a receiving space for ¹ convex sleeve parts as a counter surface, the sleeve parts being arranged on both sides of a holder with a receiving opening and one
Have freedom of movement for the sleeve.

This makes it possible to insert the sleeve parts into the holder in the form of a wall from different sides insert and the thus fixed sleeve parts

to use with their convex surfaces as a guide for the associated enclosing half-shells.

An advantageous embodiment is that the Convex surfaces of the two sleeve parts in the installation state form parts of a spherical surface.

In order to ensure easier installation, it is proposed that one of the concave half-shells be detachable

A functional arrangement to improve the tightness and the storage is formed by | 'j that the concave half-shells against spring elements

the convex surfaces of the sleeve parts are pressed.

concave half-shell 8 with an associated locking nut 9 on approximately spherical mating surfaces of slide convex sleeve parts 10,11. Here, the sleeve parts 10, 11 are received through the bore 5.

The half-shell 8 and nut 9 are set so that that there is a minimal axial play within the device and this is thus a seal against air ~ and water will pass through, such as disses for partition walls between the crew room and the engine room required by heavy vehicles. The tightness between the actuating linkage 1 and the wall 6 can can be produced by an elastic bellows 12.

Half-shells 13 »14 are detachably connected to the sleeve 15. In this case, spring elements 16 ensure a backlash-free installation of the bearing and the compensation of any occurring manufacturing inaccuracies within the storage.
