ABSTRACT:
A combination car system is made up from a first car and a second car, both of which are capable of running independently. The first car includes a pair of front wheels by which it is driven, a pair of rear wheels, a first engine, and a first transmission which drivingly couples this first engine to the front wheels. The second car includes a pair of front wheels, a pair of rear wheels by which it is driven, a second engine, and a second transmission, which drivingly couples this second engine to the rear wheels, and which is an automatic transmission which can be set to at least N, D, L, and R ranges according to the position of a switching valve. The first car and the second car are couplable together into a combination car which runs on the front wheels of the first car and on the rear wheels of the second car, the rear wheels of the first car and the front wheels of the second car being at this time removed from road contact. At this time, an electrical connecting system provides control by a first electrical switching system fitted in the first car to an electrically operated servo device which positions the switching valve of the automatic transmission of the second car to any one of the above ranges. On the other hand, when the cars are running independently, at this time the electrical connecting system provides control by a second electrical switching system fitted in the second car to this electrically operated servo device. Thus, when the cars are coupled together into the combination car, the operation of the automatic transmission of the second car may be controlled from the first car by operating the first electrical switching system, and the controlling operation of the second electrical switching system is at this time unavailable.
