Description
technical field [0001] The invention relates to a Y-direction vibration attenuation device for an electric vacuum pump of a new energy vehicle. Background technique [0002] The vacuum boosting effect of the braking system is related to the driving safety of the car. In the automobile brake booster system, because the vacuum booster cannot obtain vacuum or the vacuum obtained is insufficient, the boosting effect of the brake system will be poor. The electric vacuum pump can monitor the change of vacuum in the booster through the vacuum sensor, so as to ensure that the driver can provide sufficient boosting effect under various working conditions. Electric vehicles are driven by electric motors, which cancel the traditional engine, so they lose the source of vacuum, that is, they cannot provide vacuum boost for the brake master cylinder of the car. The electric vehicle vacuum booster pump is produced to make up for this deficiency. The electric vehicle vacuum booster pump ...
