which shock, absorption occurs during spacecraft rotation after linkage, determines the possible angle between the longitudinal axis shock absorbers and the size of the protruding elements on the docking frame determine the course of the rod , substantially affecting the longitudinal dimensions of the docking mechanism. The length of the rod of the docking mechanism with levers on the hull is minimal, and consequently, a docking mechanism with this type of equalization mechanism has minimal dimensions for an extended and retracted rod. In this scheme • wo types of angular limiters are possible: with a support into the mobile levers, and immobile (relative to the hull of the docking mechanism) angular limiters. In the latter there is no load on the lever mechanism in angular shock absorption, which is advantageous. This type of docking mechanism has the minimum possible value of angle for which, in full retraction, the supports do no touch the hull. When the conicity is changed the minimum value of also changes. To decrease the longitudinal dimensions of the docking mechanism it is expedient to increase the conicity ; thus, for example, in the Soyuz- Salyut docking device, in which the docking mechanism is located on the tunnel hatch, a scheme with an equalizing mechanism on the hull is used and . 2.6.3. Signaling Characteristics When the head of the rod of the docking mechanism is spherical and relatively small, it is easy to create a compact contact sensor construction which provides for activation for arbitrary contact of the head with the cone in a certain range of angles between the longitudinal axes of the spacecraft. Thus, the activation of this sensor for various errors is excluded. When errors are made it is necessary to quickly separate the spacecraft to avoid dangerous collisions and damage to vitally important structural elements. For automatic actuation of the jet control system of the active spacecraft to “exit” during an error it is expedient to use a sensor for face contact (contact sensor 2 in the Soyuz and Soyuz-Salyut
