<p>The first coupling member (10) on the first vehicle has an optical transmitter (38) and a spring-loaded transparent transmission member (18) with a concave outer end. A similar transmission member on the second coupling member (12) has a convex end which fits closely against the concave end of the first transmission member. The two members are buried in load carrying couplings for the vehicles and can accommodate angular misalignment. The second element is spring-loaded toward the first. There is an optical receiver (40) on the second vehicle. The transparent transmission members have opaque sheaths (22).</p> |
