More Information
Summary:A transmission for a manually operated wheeled machine includes an output shaft having a close-ended axial channel. A drive gear mounted on the output shaft includes an engaging groove. A ratchet is received in the channel and is in engagement with the engaging groove. A holder mounted on the output shaft includes a relief that receives the ratchet. A friction member applies radial friction to the holder to temporarily prevent rotation of the holder with the output shaft in a drive condition of the machine moving the ratchet into engagement with the engaging groove, and in the drive condition the drive gear and holder rotate with the output shaft. In a freewheeling condition of the machine the output shaft is stationary, and an overdrive of the drive gear disengages the ratchet from the engaging groove allowing for free rotation of the drive gear about the stationary output shaft.
