The invention relates to an integral low-latency intermediate shaft
brake. The integral low-latency intermediate shaft
brake is mounted at the front end of a transmission intermediate shaft and comprises a
brake shell connected with a transmission shell. Three gas paths are formed on the brake shell, and one end of the first gas path is plugged. A quick release valve, a
piston, five friction plates, five steel sheets and an ejector pin pressed into the
piston are arranged in the brake shell. The simple-structure quick release valve device is integrated in the control gas path, when braking isrelieved, a brake
gas cylinder exhausts gas, a
solenoid valve is controlled not through the brake, the quick release valve directly exhausts gas, the retardation time for relieving brake is shortened,and the
system response speed is increased; the integrated structure is adopted, the quick release valve, the
piston, the friction plates, the steel sheets and the like are integrated in the brake shell, the
system integration level is high, adaptability is strong, and convenience of assembling and maintenance is improved; and the dual sealing structure is adopted by the piston, gas and oil sealing of the two sides of the piston is achieved through two identical Y-shaped sealing rings, sealing is achieved reliably, and cost is low.
