Shulou(Shulou.com)11/24 Report--

CTOnews.com November 14, CTOnews.com learned from ZF official account that at the "next Generation Travel Day" held this week, ZF, a global automotive partner and parts supplier, showed off a new dry braking system for the first time. The braking force of each wheel of the system is completely generated by the motor, without the need for hydraulic system and brake fluid. The system is developed for the global market by ZF's R & D centers in China, the United States and Germany.

This dry on-line braking system does not need to use brake fluid, and its braking pressure is directly driven by the motor rather than through hydraulic pressure. The braking interaction from the brake pedal to the brake is done through communication signals, which is the origin of the term "dry" on-line braking.

Officials say new on-line braking systems, such as the Integrated Brake Control system (IBC), can achieve shorter braking distances, better braking energy recovery, and lower maintenance costs than traditional braking systems.

At 100km/h speed, the braking distance of the automatic emergency braking function of the wire control system can be as high as 9 meters shorter than that of the traditional braking system. In addition, the on-line braking system can better match the braking energy recovery and increase the mileage by up to 17%.

Compared with the traditional braking system, the dry-by-wire braking system can achieve almost zero residual drag torque by reducing the contact between the brake pad and the brake disc, so the dry-by-wire braking system can reduce the particle emission caused by wear and reduce driving resistance. save energy and increase the mileage of electric vehicles.

In ZF's new dry on-line braking system, the braking force of each wheel is generated entirely by the motor without the need for a hydraulic system. Eliminating the hydraulic system also means fewer system components, which can significantly reduce the assembly and logistics costs of vehicles in the production process. During the use of the vehicle, as the brake fluid no longer needs to be replaced, the corresponding maintenance work will be reduced accordingly, and users will also benefit from this.

ZF said that although there is no longer a mechanical connection between the brake pedal and the brake actuator, the user's braking experience will still be the same as the hydraulic brake. All connections, systems and power supplies are backed up in the system to ensure the security of data transmission and processing, similar to the on-line control systems commonly used in the aviation field.

The main engine factory can combine the best braking scheme according to its own needs, including from the classical pure hydraulic braking system to the brand-new all-dry line-controlled braking system. For example, the front axle can use a hydraulic system and the rear axle can use a hybrid mode of dry wire-controlled braking system. In addition, ZF provides one-stop supply of all components of the braking system, including wheel brakes to parking brakes, as well as a comprehensive range of products from hardware to software.
