A charge-air hose assembly includes a charge-air hose () for connecting to a pipe stub (). The charge-air hose (), in the assembled position, is pushed into the pipe stub () in such a way that overpressure occurring in the charge-air hose () presses the charge-air hose () radially outward against the radial inner wall () of the pipe stub (). The charge-air hose () is assigned a latching device which, during the insertion of the charge-air hose () into the pipe stub (), latches with the pipe stub () so as to axially fix the charge-air hose () to the pipe stub () in a predetermined axial position of the charge-air hose () relative to the pipe stub ().

Charge-air hose assembly

A resilient shaft coupling having two metal parts that include an inner coupling ring and, coaxial thereto, an outer coupling ring. The facing generated surfaces of the rings are formed with a number of substantially radial cams or dogs which mesh with one another alternately in the circumferential direction and extend to near the pertaining opposite generated surface. Each two circumferentially consecutive cams or dogs form a pair whose adjacent surfaces are concave and delimit a chamber whose longitudinal axis extends parallel to the rotational axis of the coupling, and in which a resilient coupling member is disposed. The coupling members are radially biased or pre-loaded by a predetermined amount, and are secured to the generated surfaces of the inner and outer ring coupling rings. With the coupling in its rest position, gaps or spaces are present between each resilient coupling member and each cam or dog, and permit the members to deform freely and thus to be stressed in shear. The advantage of this shear compression is that the coupling has a very reduced torsional stiffness at low torques, and operates without backlash or play at low torques.
