Explanation: is what I think must be meant here. Reading between the lines (as it were!)I fancy you are translating something to do with replacement of change-of-gauge facilities at Brest / Terespol gr., by an on-train mechanism.
If so, it works like this: wheels are mounted on an axle which is basically in two parts, splined shafts beings secured by some sort of locking device. (Splined shafts are, or were, used in the motor industry to allow propeller-shafts for example to "stretch"). In some way I've yet to figure out, it is now possible to change gauge on one of these specially-equipped vehicles at a speed of up to 275 Km/h.
The mind positively boggles!
The reference below will give a description of the design (or perhaps that's where the question came from?)
Without more context, you'll not be likely to get sensible answers in a case like this

Explanation: The new boogie is based on a fixed axle. Two sliding elements have been build on it; i.e., two elements that can be moved to the centre or ends of the axles. Bearings have been put on these elements, and finally, wheels have been put on the bearings. A reducer has been installed in the centre of the axle using a hollow shaft. This hollow shaft has been installed in the main axle by taper roller bearings. At the same time, the hollow shaft uses a cogged coupling and a flexible coupling to join with the wheels. On the other side, above the hollow shaft there are two disk-brakes. In order to ensure that the distance between the wheels is the appropriate one, some rivets and pins have been put in the Brava boogie. The pins support the sliding elements; the rivets joint the body and the mechanical elements of the axle. In addition, the Brava boogie has also a safety rivet to ensure that the distance between the wheels is at all times adequate. That way, the rest of the rivets and pins will not undo while the train is moving in a normal speed. http://www.globaltechnoscan.com/19thSep-25thSep01/brava_axle...

Explanation: I think of a "dog clutch" common on synchros for various kinds of gearboxes or comparable mechanisms
(you will find by yourself multiple occurrences of "dog clutch" if my idea of a typo may be useful)

The updates to the menu were made to make the site easy and more intuitive for visitors. Obviously, like any change, this may take a few days to get used to.
The dropdown menus have been divided into two-dimensional panels with similar items grouped together under headings. This eliminates scrolling for those with smaller screens, and also improves readability.
Mouseover your name at the top of the screen. Here you will find information about your account, your email settings, and more. The "My ProZ.com" menu was moved up here to simplify the main navigation, and to keep all of this type of information together.
