AI Technical Summary
Existing axle systems are complex in structure, have many components and occupy a lot of space, traditional wheel disc brakes suffer from wear and environmental pollution, and parking management systems lack redundancy.
The system replaces traditional wheel disc brakes with wet-operation diaphragm brakes and achieves uniform or non-uniform braking of the wheels through an electronic control unit. It provides redundant parking functions by combining diaphragm brake parking actuators and parking locks, and uses a self-locking mechanism to ensure that the braking force is maintained.
It simplifies the axle structure, reduces the number of components, avoids brake wear, improves the redundancy and reliability of the parking management system, and reduces environmental pollution.
