Description
Technical field
The present invention relates to the disc brake component with one or more rotating disks, rub in the rotating disk with annular
Wipe surface, against friction surface be for rotating disk apply brake force stress static friction plate/gasket.Especially
Ground, the present invention relates to the disk brake of the type with brake strip, the brake strip is by for providing required system
The spring actuated of power disconnects or starts the torque on the disk to contact the annular friction surface on rotor disk.This seed type
Disk brake utilize in response to the Fluid pressure applied in annular pressure chamber annular piston to be axially moveable this
Piston is to make piston sheet from annular disk release and therefore discharge the brake force on disk.
Background technique
The disk brake of the above-mentioned type is used for heavy-duty machine application, such as oil well drill pipe and surface mining equipment；And
It has been desirable in certain applications, may be used as urgent brake.One example of such brake, which uses, has 50 inches
The disconnection of the diameter and 5,578,000in-lbs (630,282 Ns of rice) of (127cm) or the rotor disk of starting torque.
Referring to Fig. 6 and 7, friction plate is already installed on pressure plare 1, and pressure plare 1 is fixed to shape by spacer 4 and bolt 5
Circularize the shell 2 of pressure chamber 3.The annular piston 6 being set in chamber 3, which has, to be slidably housed on spacer 4
Aperture.Pressure plare 1 has the aperture being slidably received on spacer 7；And piston 6 is via the spiral shell for crossing spacer 7
The Peripheral-array and lock nut 19a of line column 19 are fastened on annular static installation plate 8, so that the fluid pressurization of chamber leads to shell
It is moved axially with pressure plare 1.Rotor disk 9,10 is accepted on drive hub 11 and spline connection on it is to allow the disk
It is moved axially on spline 10 about wheel hub 11, while maintaining to engage with the rotate driving of wheel hub.Multiple brake pressure springs 12
It is arranged around piston 6 with Peripheral-array, one end of each spring abuts piston 6, and the opposite end of each spring abuts pressure plare 1.
In operation, when there is no Fluid pressure in chamber 3, spring 12 in figs. 6 and 7 push up pressure plare 1 and shell to the left
2, so that the friction plate 14 being arranged in around rotor disk 9 is pressed against on the annular friction surface of rotor, and keep rotor disk 9 mobile
To contact with the friction plate 15 being mounted on axially movable annular reaction plate 16, reaction plate 16 can be slided on spacer 7
It moves axially dynamicly, but by bolt 19 and the limitation of spacer 7 without being able to rotate.There is reaction plate 16 setting to rub surrounding
