Principle of work: the pressure air by locomotive control pipe operation brake pipe, be divided into inflation, maintenance and exhaust and have three active positions respectively, be service application position, pressurize position and alleviation position.
Service application position: locomotive is inflated to brake pipe, pressure air enters the air inlet base mouth of cylinder body, pressure air promotes piston and moves, yet driving guiding nut, leading screw, adjustment nut and extension bar by piston rod is moved to the left together, till brake shoe and vehicle recline, be in service application position.
The pressurize position: locomotive operation brake pipe inflation pressure air keeps not increasing when not subtracting, and this moment, drg was the service lap position.
Alleviate the position: the pressure air row of locomotive operation brake pipe is when atmosphere is zero.Because of the pressure air on piston right side has arranged zero, this moment, piston was subjected to the elastic force effect of release spring to reset to original alleviation position, and piston rod, leading screw composition are also got back to together and alleviated the position simultaneously.
Track traffic passenger vehicle vehicle unit brake design advantage:
1. owing to having adopted integral threaded connection structure between piston and the piston rod, when piston is subjected to
When the fast aeration pressure, piston is subjected to the restriction of piston rod, thus piston just can not tilt,
This structural development is the main inventive point of present patent application, greatly reduces piston back seal circle
Resistance improves having guaranteed braking and the basic function of alleviating.
2. has function commonly used, that emergency braking improves braking force.
3. the jump ring structure that has conveniently assemble and disassemble has substituted loaded down with trivial details bolt fastening structure.
4. but have the brake clearance self-align effect of brake shoe abrasion back, guaranteed car brakeing
Not waning property of power is guaranteed the safety of driving a vehicle.
5. have manual replacing brake block, but the function of hand adjustment leading screw length mechanism.
