Benefits of technology

This technology helps save power when it works with an air conditioner (AC) system that uses compressed gas instead of liquid water). It also allows for more efficient use of space inside the AC's housing without losing any extra weight or reducing coolant flow rate due to increased pressure on certain parts of the circuitry caused by the compressor being used during normal operations.

Problems solved by technology

This patented technical problem addressed by this patents relates to improving the efficiency of electrically driven cars' brakes while reducing costs associated therewith without compromizing safety features like traditional hydraulostic/pneumatics type braks that require frequent maintenance and replacement.

Abstract

The invention provides a vacuum-assist braked power device for an electric vehicle. The vacuum-assist braked power device for the electric vehicle is arranged between a brake drum and a vacuum pump and comprises a power take-off wheel, a drive shaft, a magnetic disc, a copper disc, a spline shaft and a sleeve shaft which are arranged sequentially. The power take-off wheel is in contact with an inner disc of the brake drum, the sleeve shaft is connected with the drive shaft of the vacuum pump. A steering wheel is arranged on the spline shaft and a steering fork is clamped outside of the steering wheel. The two ends of a joystick are fixedly connected with the steering fork and a driven magnetic disc correspondingly, the driven magnetic disc is connected with a magnetic disc spline shaft in a sliding mode, a driving magnetic disc is fixedly connected with the magnetic disc spline shaft. The side of the driving magnetic disc is fixedly connected with a brake pin which is connected with an inhaul cable of a brake pedal. A first sector magnet of which the N-pole faces the driving magnetic disc and a second sector magnet of which the S-pole faces the driving magnetic disc are arranged on the driven magnetic disc, and a third sector magnet of which the N-pole faces the driven magnetic disc is arranged on the driving magnetic disc. The vacuum-assist braked power device for the electric vehicle realizes operating of the vacuum pump by recycling partial braking capacity, and saves energy while realizing braking assist.
