Problems solved by technology

Some movable equipment on the ship adopts the active braking method with brake universal wheels. The active braking method has great safety hazards under the condition of human operation, and each wheel needs to step on the brake when braking. The mobile equipment The braking and unlocking processes cannot be controlled at the same time, which is very inconvenient during use
The normally open hydraulic disc brake device used on the electric tricycle on the market, when the pressure oil provided by the hand brake pump acts on the two disc brakes at the same time, due to the different frictional resistance of the sealing device, the The pistons can't move at the same time, so they can't brake at the same time, resulting in serious dynamic load unbalanced load and affecting the driving direction

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...
