| 摘要 |
The invention involves the manual driving mechanism for a three- or more wheel vehicle, such as to enable transmission of circular hand-driven movement through gear connection of the main gear (1) and the intermediate gears (2, 2'), as well as via friction wheels (2a, 2b, 2a', 2b') to the driven wheel (4) of the vehicle with appropriate shift ratio and simple driving control forwards or backwards along with the possibility of braking and sudden stopping and/or blocking of the driven wheel (4). The mechanism is constructed in the way that it can be mounted and/or built on to the existing vehicle, e.g. a wheelchair following a simple intervention. |
