초록 ▼

A vehicle connectable to an auxiliary power unit capable of energizing a pair of fail-safe brakes that arrest rotation of a pair of electric transaxles mounted to the vehicle. Each brake has an external connector and requires electrical power to assume a non-braked state that permits free rotation of an electric motor engaged to the brake and incorporated in each of the electric transaxles. The auxiliary power unit having first and second circuits and first and second connectors compatible with the external connectors of one of the brakes.

대표청구항 ▼

1. An auxiliary power unit capable of energizing a pair of fail-safe brakes that arrest the rotational output of a pair of electric transaxles mounted to a vehicle, each electric transaxle having a separate electric motor engaged to one of the pair of brakes, and each brake having an external electrical connector and requiring electrical power to assume a non-braked state that permits free rotation of its respective electric motor, the auxiliary power unit comprising: a first switchable circuit comprising a first power source connected in parallel with a first visual indicator and a first electrical connector compatible for connection with the external electrical connector of one of the brakes;a second switchable circuit comprising a second power source in parallel with a second visual indicator and a second electrical connector compatible for connection with the external electrical connector of the other of the brakes; anda switch in electrical communication with the first and second switchable circuits, wherein when the switch is closed: the first and second power sources are electrically connected to the first and second visual indicators, respectively; andthe first and second power sources supply the electrical power to the first and second electrical connectors, respectively, such that the brakes assume the non-braked state when the first and second electrical connectors are connected with the external electrical connectors of the brakes. 2. The auxiliary power unit of claim 1, further comprising a case enclosing the first and second power sources. 3. The auxiliary power unit of claim 1 wherein the first and second visual indicators comprise light-emitting diodes. 4. The auxiliary power unit of claim 1, wherein the switch is a double pole single throw switch. 5. The auxiliary power unit of claim 1, wherein the first power source and the second power source comprise a plurality of batteries. 6. The auxiliary power unit of claim 1, wherein the auxiliary power unit is configured to be mounted to the vehicle. 7. The auxiliary power unit of claim 1, wherein the first electrical connector and the second electrical connector comprise two-wire connectors. 8. The auxiliary power unit of claim 2, wherein the first and second visual indicators are mounted on the exterior of the case. 9. The auxiliary power unit of claim 2, wherein the switch is mounted on the exterior of the case. 10. The auxiliary power unit of claim 2, wherein the first and second electrical connectors are external to the case and communicate electrically with first and second switchable circuits, respectively, through a pair of extended leads. 11. The auxiliary power unit of claim 5, wherein each of the plurality of batteries comprises a 9V cell. 12. A vehicle comprising: a pair of electric transaxles driving a pair of output shafts, each electric transaxle comprising an electric motor;a pair of fail-safe brakes each engaged to one of the electric motors, each fail-safe brake having an external electrical connector for receiving electrical power, wherein each fail-safe brake arrests the rotational output of one of the pair of electric transaxles and requires the electrical power to assume a non-braked state that permits free rotation of the electric motor engaged to the brake; andan auxiliary power unit comprising: a first switchable circuit comprising a first power source connected in parallel with a first visual indicator and a first electrical connector compatible for connection with the external electrical connector of one of the brakes;a second switchable circuit comprising a second power source connected in parallel with a second visual indicator and a second electrical connector compatible for connection with the external electrical connector of the other of the brakes; anda switch in electrical communication with the first and second switchable circuits. 13. The vehicle of claim 12, wherein the auxiliary power unit further comprises a case enclosing the first and second power sources. 14. The vehicle of claim 12, wherein the first and second visual indicators comprise light-emitting diodes. 15. The vehicle of claim 12, wherein the switch is a double pole single throw switch. 16. The vehicle of claim 12, wherein the first power source and the second power source comprise a plurality of batteries.
