It can achieve a parking capacity of over 30% on slopes, far exceeding the regulatory requirement of 20% for parking.

The assembly is directly integrated at the wheel edge, with a short parking cable, 100% return performance, and nearly zero drag torque, which is beneficial for extending the vehicle’s range. And it responds quickly (<1.5s), with a decrease in MGU parking force of<10%, which is conducive to vehicle calibration.

It can achieve functions such as manual parking release and reclamping on sloping terrain, improving safety and reliability.

The highly sealed waterproof structure design avoids the risk of EPB actuator failure due to water ingress.

Design a dedicated structure for after-sales repair: when the vehicle harness fails and cannot be powered on to release the parking, the after-sales repair structure can be used to release the parking operation.

The bidirectional self increasing drum EPB realizes dual self adjustment of parking and driving, achieving shorter travel time, occupying less space, facilitating layout, and good platformization.
