Description

technical field

[0001] The invention relates to the technical field of hydraulic brakes, in particular to a constant-lock hydraulic disc brake device. Background technique

[0002] Permanent lock brake means that the brake device is in the braking state without human operation. At present, it is mainly used in baby carriages, airport luggage carts, medical equipment, supermarket shopping carts, and other non-powered wheeled transport tools to prevent Personnel and equipment damage due to vehicle rolling on slopes, unintentional bumps and vibrations. At present, most of the strollers on the market adopt the active braking method, as shown in the patent No. CN200620149310.0 utility model, which requires the guardian to stop the stroller and step on the brake pedal to increase the static friction between the brake and the wheels. Realize the locking of the wheels. Once the guardian does not step on the brake pedal due to negligence, the brake device cannot be started. The pate...
