Title:
DOUBLE-SPEED MOTOR FOR ELECTRIC CONTROLLED SPEED-CHANGING ELECTROMOBILE
Document Type and Number:
WIPO Patent Application WO/2011/153883
Kind Code:
A1
Abstract:
A double-speed motor for an electric controlled speed changing electromobile comprises a casing, a stator (2), a rotor (1) and a shaft. The output end of the rotor (1) is drivingly connected with positive and negative driving chains. The driving mediums located at the output end of the positive and negative driving chains are drivingly connected with output transmission components by unidirectional clutches respectively. The clutch between the negative driving medium and the output transmission component is a controllable unidirectional clutch, and the positive driving medium drives a transitional sleeve (7.3) through a unidirectional clutch. A circumferential notch is formed between the transitional sleeve (7.3) and the coaxial output transmission component, and a stopper is provided in the circumferential notch. The transitional sleeve (7.3) pushes an additional transmission mechanism by the stopper, and the additional transmission mechanism can promote the controllable unidirectional clutch to move. When the electromobile rolls back, the additional transmission mechanism can produce interlock and clear self-locking of the electromobile.
