Abstract
A drive system includes a hollow axle with a jackshaft that extends therethrough and is mounted to extend parallel thereto. Bearings rotatably connect both the hollow axle and the jackshaft to first and second chassis portions. A first end of the jackshaft extends beyond the hollow axle and is connected to a motor by a pair of clutches interconnected by a drive belt. A second end of the jackshaft extends beyond the opposite end of the axle and has a drive sprocket attached thereto that is interconnected to a first idler sprocket on an idler shaft by a first drive chain. A second idler sprocket is connected to a driven sprocket, which is affixed to the axle, by a second inboard drive chain.
Claims8
A drive system for a motorized machine, said motorized machine including a motor, said drive system comprising:
- a) a hollow axle extending between first and second chassis portions;
- b) first bearing means mounting each end of said hollow axle in one of said first and second chassis portions;
- c) a jackshaft extending through said hollow axle and extending beyond each end of said hollow axle;
- d) second bearing means mounting each end of said jackshaft in one of said first and second chassis portions;
- e) a driven means attached to a first end of said jackshaft which extends beyond a first end of said axle, said driven means being interconnected to a drive means by first endless flexible drive means;
- f) interconnecting drive means attached to a second end of said jackshaft and a second end of said axle opposite said first ends, respectively, said interconnecting drive means including
- i) a drive sprocket affixed to said jackshaft;
- ii) an idler shaft spaced from and parallel to said jackshaft;
- iii) a first idler sprocket affixed to said idler shaft;
- iv) a second endless flexible drive means interconnecting said drive sprocket and said first idler sprocket;
- v) a second idler sprocket mounted on said idler shaft inboard of said first idler sprocket;
- vi) a driven sprocket affixed to said axle;
- vii) a third endless flexible drive means interconnecting said second idler sprocket and said driven sprocket;
- whereby drive torque is adapted to be transmitted from the motor to said jackshaft from the drive means to the driven means by said first endless flexible drive means and from said jackshaft to said axle by said drive sprocket through said second endless flexible drive means to said first idler sprocket, from said first idler sprocket to said second idler sprocket through said idler shaft, through said second idler sprocket to said driven sprocket which is affixed to said axle, by said third endless flexible drive means.
