Technical field
The present invention relates to new-energy automobile spare and accessory parts fields, and in particular to a kind of new energy vehicle electronic parking wheel motor use
Denoising device.
Background technique
Currently, EPB(Electrical Park Brake) be electronic brake system english abbreviation, EPB passes through interior
The longitudinal acceleration sensor in its computer is set to calculate the gradient, is produced on the slope due to gravity so as to calculate vehicle
Raw sliding force, computer apply brake force to rear-wheel to balance sliding force by motor, enable the vehicle to stop on the slope.Work as vehicle
When starting, computer calculates the brake force for needing to apply by the size of displacement sensor and throttle on clutch pedal,
The size to know engine traction is communicated by high-speed CAN and engine computer simultaneously.Computer calculates engine automatically and leads
The increase of gravitation, reduces brake force accordingly.When tractive force overcomes sliding force enough, computer driving motor releases braking, from
And realize the smooth starting of vehicle.The system can guarantee vehicle steadily halt on 30% slope.In addition the system is realized automatically
Thermal compensation, i.e., if vehicle parking after forcing to move, rear brake disc can be because of temperature decline and friction plate generation gap, at this time
Motor can start automatically, and driving clamp nut comes the gap that compensation temperature decline generates, and guarantee reliable parking effect.
Traditional EPB motor, noise is larger, and because its be in wheel side position, tire high speed rotation and brake when heating compared with
Height cannot wrap up, and be not easy to do noise reduction schemes.Existing noise reduction mode, general using acoustical cotton is increased, the devices such as rubber pad are dropped
It makes an uproar, but because brake heating can be to 300 ~ 500 degree, and acoustical cotton cannot be wrapped up all, and noise reduction effect is general when EPB works.
