Detailed Description
A special brake cylinder for a muck truck is composed of a spring energy storage brake cavity 1, an operation brake cavity 2, an air pipe 3, a fixed push rod 4, a piston 5, a movable push rod 6, a hollow connecting shaft 7, a brake cylinder shell 8, a brake spring 9, a leather cup 10, an outer connecting nut 11 and a check ring 12, wherein the spring energy storage brake cavity 1 is arranged on the left side of the brake cylinder shell 8, the operation brake cavity 2 is arranged on the right side of the brake cylinder shell 8, the piston 5 and the brake spring 9 are arranged in the spring energy storage brake cavity 1, the leather cup 10 is arranged in the operation brake cavity 2, and an air hole interface 14 is arranged on the spring energy storage brake cavity 1; a hollow connecting shaft 7 is fixedly arranged in the middle of the piston 5, the other end of the hollow connecting shaft 7 is arranged in the middle of the brake cylinder shell 8 and can slide left and right on the brake cylinder shell 8, and a sealing ring 13 is arranged on the contact surface of the hollow connecting shaft 7 and the brake cylinder shell 8. The left end in the hollow connecting shaft 7 is provided with a fixed push rod 4, and the other end of the fixed push rod 4 is fixed on the left side of the brake cylinder shell 8; the right end in the hollow connecting shaft 7 is provided with an external nut 11, the center hole of the external nut 11 is provided with a movable push rod 6, the movable push rod 6 is fixed with the external nut 11 through a retaining ring 12 welded at the left end, and the right end of the movable push rod 6 passes through a leather cup 10 and then extends out of the brake cylinder shell 8. The hollow connecting shaft 7 and the movable push rod 6 are connected into a whole through a connecting outer nut 11 and a check ring 12 and move along with the left and right movement of the piston 5.
The working process of the special brake cylinder for the muck truck comprises the following steps:
when braking is needed, air pressure in the spring energy storage braking cavity 1 is released, the braking spring 9 pushes the piston 5 to move rightwards, and meanwhile, the hollow connecting shaft 7, the connecting outer nut 11, the check ring 12 and the movable push rod 6 are driven to move rightwards together, so that the movable push rod 6 extends out to push the right braking mechanism to brake; meanwhile, as the special brake cylinder for the muck truck is horizontally mounted in a suspension manner, when the movable push rod 6 pushes the right brake mechanism to brake, the reaction force pushes the brake cylinder shell 8 to drive the fixed push rod 4 to move leftwards so as to push the left brake mechanism to brake. In order to prevent vacuum from forming on the left side of the piston 5 and influence the pushing force of the brake spring 9 pushing the piston 5, the left side of the piston 5 is fed with air from the outside of the leather cup 10 through the air pipe 3.
When the brake needs to be released, air enters the spring energy storage brake cavity 1 through the air hole interface 14, so that the piston 5 moves leftwards to compress the brake spring 9, and meanwhile, when the piston 5 moves leftwards, the hollow connecting shaft 7, the connecting outer nut 11, the check ring 12 and the movable push rod 6 are driven to move leftwards together, so that the right brake mechanism is released; meanwhile, as the special brake cylinder for the muck truck is horizontally suspended, when the movable push rod 6 moves leftwards to release the brake mechanism, the fixed push rod 4 also moves rightwards to release the brake of the left brake mechanism.
In order to ensure the pressure in the spring energy storage brake cavity 1, a sealing ring 13 is arranged at the contact surface of the hollow connecting shaft 7 and the brake cylinder shell 8, and a sealing ring is also arranged at the contact surface of the piston 5 and the brake cylinder shell 8.
While the foregoing is directed to embodiments of the present invention, other and further embodiments of the invention may be devised without departing from the basic scope thereof, and the scope thereof is determined by the claims that follow.
