Abstract: A frame for a vehicle to accommodate a large-sized accessory, such as a fuel tank, to be mounted downwardly of a rear pipe without having to lower a rear sub-pipe. A large-sized accessory, such as a fuel tank, can be inserted into a space under a rear pipe by removing a second rear sub-pipe from a main frame and the rear pipe. The second rear sub-pipe can be fixed to the main frame and the rear pipe by simply tightening bolts. Similarly, by simply loosening the bolts the second rear sub-pipe can be removed from the main frame and the rear pipe and the large-sized accessory can be removed onto an outside in a vehicle width direction. This facilitates mounting and helps reduce the number of man-hours involved in mounting the accessory.

The rotating axle is rotationally disposed on a frame body and has two cranks with force-receiving members disposed at the two ends thereof, for allowing the force received by the force-receiving members to provide a rotational force to drive the rotating wheel to rotate and thus facilitate the auxiliary motor to output power, wherein the auxiliary motor is disposed between the two cranks disposed at the two ends of the rotating axle, and wherein the auxiliary motor includes a magnetic field having the same axle center as or parallel to the axle center, thereby facilitating the auxiliary motor to output power in cooperation with the rotating power provided by the rotating axle to synchronically drive the rotating wheel.

Abstract: A trailer converter dolly includes a frame bearing a fifth wheel supported by a suspension mechanism, an axle assembly, and a wheel assembly. A drawbar housing secured to the front of the frame moveably receives a drawbar which is configured to move toward and away from a leading truck or trailer, thus adjusting the distance between the towed trailer attached to the trailer converter dolly and a leading truck or trailer. A speed sensor determines the speed of the trailer converter dolly and provides one or more signals relating to the speed of the trailer converter dolly. An automatic adjusting mechanism associated with the moveable drawbar moves the drawbar in response to the one or more speed signals provided by the speed sensor.
