Trailer coupling for vehicle; has ball rod with shaft held in coupling support connected to vehicle and secured by locking unit with adjustable transverse bolt that engages radial recess in shaft

摘要

The coupling has a ball rod (1) with a shaft that can move between rest and working positions and a coupling ball (2). The shaft is held in a coupling support (3) connected to the vehicle and is secured in the working position by a locking unit. An axially adjustable transverse bolt of the locking unit is arranged transverse to the shaft of the ball rod and engages a radial recess in the shaft of the ball rod to lock the ball rod. The transverse bolt slides axially in a guiding transverse bolt in the coupling support and is spring-biased in the direction of the ball rod or the radial recess. The free end of the transverse bolt has a handle (4) to unlock the transverse bolt against the spring force and out of the recess.
