The invention discloses a commercial vehicle driving and parking electromechanical braking actuating device and a braking method, and belongs to the field of vehicle braking control systems. Cylinder bodies of the parking brake motor, the service brake motor and the self-locking mechanism are fixedly connected to the brake shell. A parking brake sleeve of the self-locking mechanism is in sliding connection with the cylinder body; the push rod pushes a rocker arm of the brake of the commercial vehicle along with the linear sliding of the service braking rack rod; the service braking rack rod penetrates through the self-locking mechanism, a service braking rod baffle is fixedly connected into the self-locking mechanism, and the service braking rod baffle is attached to the parking braking sleeve in the parking state. The parking braking sleeve extends out of the self-locking mechanism, and the part, outside the self-locking mechanism, of the parking braking sleeve is provided with a parking braking tooth part meshed with the parking braking pinion. The parking spring can be locked in a pure mechanical self-locking mode, and the working time of the parking motor is greatly saved.
Description
technical field [0001] The invention belongs to the technical field of vehicle brake control systems, in particular to an electromechanical brake actuation device and a brake method for driving and parking commercial vehicles. Background technique [0002] With the development of society, the demand for logistics and transportation is increasing, and the proportion of commercial vehicle transportation is increasing. As an important part of active safety, the braking system is becoming more and more safe and reliable. It has attracted the attention of OEMs and brake manufacturers. At present, the existing commercial vehicle air pressure braking system has the disadvantages of large volume, complex structure, slow braking response, and high failure rate; and the noise is large when the brake chamber is exhausted; the air pressure brake consumes the power of the engine; Stable, resulting in poor driving comfort. [0003] Brake-by-wire technology is a new type of braking techn...
