Description: |
| Abstract:
Comprises the combination of a frame 1a, a. slow or medium speed internal-combustion engine 1 mounted thereon, a gear-box 4 also mounted on the frame and driving the road wheels, and an endless flexible member such as 5 transmitting the drive from the engine shaft 2 to the primary shaft 3 of the gear-box, the said primary shaft being driven at or above the speed of the engine. In the construction shown the shaft 3 is driven by the chain 5 at engine speed, but the sprockets 6, 7 can be readily changed so that the shaft 3 may be driven at a higher speed. The chain passes over a jockey pinion 8<1>, and it may be enclosed. The last shaft 8 of a change-speed gear in the gear-box drives a shaft 13 through reducing gear 12 and the shaft 13 drives the road wheels through a single reducing train 14, 15. |
