<p>PURPOSE:To secure such a small electric motor car that is excellent in safety capable of stopping it easily by installing a means which links up a brake with a negative braking device, thereby bringing the negative braking device into a state of being operated and released with the operation and release of the brake. CONSTITUTION:A wire 27 is pulled by a brake lever 16 of a handle 3 and a brake A operates. On the other hand, in an electric motor, there is provided a negative braking device B which makes brake force act on the motor shaft through energizing force by a spring, while releases the brake force by current- energization to the motor. This brake is operated with return operation of an accelerator lever 13. In this case, a limit switch 29 is wired in series in a circuit, whereby the negative braking device B is operated with operation of the brake A, while this device B is made into a state of releasing its operation with the operation release of the brake A, thereby constituting a means C linking up the brake A with the negative braking device B.</p> |
