Embodiment
Below with specific embodiment, each form content that the utility model is disclosed is described in detail.
See also Fig. 3, be schematic representation according to Drum brake of the present utility model mechanism 20, this Drum brake mechanism 20 comprise a fixed tray 22, a brake drum 21, with a connection part 25.Wherein fixed tray 22 have an axis of rotation 221, a catheter channel 222, with a plurality of Brake shoes 223.Brake drum 21 for partly be coated on the fixed tray 22 and and fixed tray 22 between form an enclosed space 23, and around axis of rotation 221 rotations.Connection part 25 is for being connected between a catheter channel 222 and the sourceof negative pressure 24.And the effect of sourceof negative pressure 24 is the interference friction factor material in the enclosed space 23 is attracted through connection part 25, reaches the effect of removing the interference friction factor material in the enclosed space 23.
Connection part 25 comprises one first conduit 252 and one second conduit 253, and wherein first conduit 252 is connected in catheter channel 222, and second conduit 253 is connected in sourceof negative pressure 24.
Again, sourceof negative pressure 24 is an outlet pipe, and connection part 25 comprises an one-way cock 253.This one-way cock 254 is arranged between first conduit 252 and second conduit 253, is used to prevent that the interior exhaust flow of outlet pipe is to enclosed space 23.And the negative pressure in the outlet pipe can be expelled to the hot gas sucking-off in the enclosed space 23 outside the outlet pipe via connection part 25 again.
Again, connection part 25 comprises a filter assemblies 251 again, this filter assemblies 251 is arranged between catheter channel 222 and the one-way cock 254, and the negative pressure in the outlet pipe can and enter connection part 25 with the dust sucking-off enclosed space 23 in the enclosed space 23, utilize the filter assemblies 251 in the connection part 25 that aforesaid dust collection is filtered, preventing that dust from entering in the outlet pipe, and this filter assemblies 251 can be a dry filter or a wet filter.
See also Fig. 4, be schematic representation according to another embodiment's provided by the utility model Drum brake mechanism 30, this Drum brake mechanism 30 comprise a fixed tray 32, a brake drum 31, with a connection part 35.Wherein fixed tray 32 have an axis of rotation 321, a catheter channel 322, with a plurality of Brake shoes 323.Brake drum 31 for partly be coated on the fixed tray 32 and and fixed tray 32 between form an enclosed space 33, and around axis of rotation 321 rotations.Connection part 35 is for being connected between a catheter channel 322 and the sourceof negative pressure 34.And the effect of sourceof negative pressure 34 is the interference friction factor material in the enclosed space 33 is attracted through connection part 25, reaches the effect of removing the interference friction factor material in the enclosed space 23.It should be noted in addition, Drum brake mechanism 30 is that with the main difference of Drum brake mechanism 20 connection part 25 comprises first conduit 252 and second conduit 253, connection part 35 then comprises a conduit 352, and this conduit 352 is connected between sourceof negative pressure 34 and the fixed tray 32.
Again, wherein sourceof negative pressure is 34 1 outlet pipes, and connection part 35 comprises an one-way cock 353.This one-way cock 353 is arranged between conduit 352 and the catheter channel 322, is used to prevent that the interior exhaust flow of outlet pipe is to enclosed space 33.And the negative pressure in the outlet pipe can be expelled to the hot gas sucking-off in the enclosed space 33 outside the outlet pipe via connection part 35 again.
