Definitions
- the invention relates to a drum brake for a motor vehicle with a rotatably mounted brake drum, with a ra dial inwardly facing friction surface, with brake pads arranged radially within the friction surface, with an actuator for biasing the brake pads against the friction surface and with egg nem anchor plate to hold the Actuator, with an opening for discharging brake debris from the brake drum and with a cover of the brake drum.
- Such a drum brake is known from WO 2018/054821 Al.
- an opening with a horizontal axis is arranged on the cover immediately on the brake drum, to which a suction device provided with a dust removal unit is connected.
- the suction device has the task of sucking off accumulating brake dust and preventing its emission into the environment.
- the invention is based on the problem of developing a drum brake of the type mentioned at the beginning in such a way that the brake debris can be easily removed.
- the bag enables the brake debris to accumulate. After a specified time or a specified level of brake abrasion, this can be removed from the pocket via the opening, for example by suction. to be removed.
- the brake debris is particularly easy to remove from the pocket. Continuous suction is therefore not absolutely necessary.
- the pocket is particularly simple in construction when the opening is spaced from the base area of the cover.
- the brake abrasion collects under the opening under the force of gravity, so that exposing the opening does not lead to an unintentional escape of brake abrasion. Since the opening is spaced from the bottom area of the anchor plate, an accidental release of brake debris when it is removed is avoided.
- the removal of the brake debris is particularly simple if the opening opens into a collecting funnel that protrudes into the pocket.
- the collecting funnel enables the resulting brake wear to be collected.
- the brake debris is thus removed as it arises from the pairing of the brake pads and the brake drum and collects ge in the collecting funnel.
- the collecting funnel can be used to influence the flow during the removal of the brake debris.
- Brake abrasion is particularly simple according to another advantageous development of the invention when the collecting funnel is arranged between two brake pads and immediately above half of the inside of the brake drum and has a trough shape to collect the brake abrasion.
- the dimensions of the pocket can easily be limited if the cover has a vertical section, if the vertical section forms a partial area of the pocket and when the opening is net angeord above the vertical section.
- the cover is designed according to another Schohaf th development of the invention particularly simple when the anchor plate and the cover are taken in one piece gefer.
- the drum brake is particularly inexpensive when the opening is closed by a plug.
- the plug can be removed during inspection and a suction tube inserted into the pocket to suck in the brake debris.
- the opening has a connection for a suction line.
- the suction line can be connected to the connection when the vehicle is being inspected, for example, or it can be kept connected at all times for continuous suction.
- the arrangement of a suction fan to be mounted separately can be avoided if the opening is connected to an intake section of an internal combustion engine.
- the brake wear is retained in the air filter that is already present.
- the suction line can be simply and permanently fixed to the opening if the opening has a pipe socket.
- Fig.l simplifies a longitudinal section through a
- FIG. 2 shows a partial area of a first embodiment of the drum brake from FIG. 1,
- FIG. 3 shows a suction cup for connection to the drum brake from FIG. 2.
- FIG. 4 shows a partial area of a second embodiment of the drum brake from FIG. 1,
- FIG. 5 shows a partial area of a third embodiment of the drum brake from FIG. 1,
- FIG. 6 shows a sectional illustration of the embodiment according to FIG. 3 along the line VI - VI.
- Figure 1 shows a simplified longitudinal section through a drum brake 1 of a motor vehicle with a rotatably gelager th brake drum 2 and a radially inwardly facing friction surface 3.
- the brake drum 2 brake pads 4 opposite.
- the brake pads 4 are arranged in pairs, as shown in FIG.
- the brake linings 4 are held on an armature plate 5 and can be pressed against the friction surface 3 by an actuator 6.
- the anchor plate 5 has a portion of the brake drum 2 overlapping cover 7. Between the brake drum 2, and a vertical portion 8 of the cover 7 is a pocket 9 is arranged in which the brake abrasion melts.
- the anchor plate 5 has an opening in an inclined section 10 arranged above the vertical section 8
- the cover 7, which is manufactured in one piece with the armature plate 5 in the present exemplary embodiment, seals the pocket 9 from the environment, so that the entry of brake dust into the environment is prevented.
- FIG. 2 shows, enlarged, the lower part of the drum brake 1 from FIG. 1 in the area of the opening 11.
- the opening 11 is closed by a plug 12.
- a suction device 13 shown in FIG. 3 can be inserted through a connection 14 of the opening 11 and the brake debris can be sucked off.
- FIG. 3 schematically shows a sucker 13 for connection to the opening 11 from FIG. 2.
- the sucker 13 has a suction line 15 for insertion into the opening 11, a fan 16 and an air filter 18. If the suction line 15 is inserted into the opening 11 introduces, the free end of the suction line 15 reaches the bottom area of the pocket 9. The brake debris can then be sucked off by means of the blower 16 and collected in the air filter 18.
- FIG. 4 shows a further embodiment of the lower part of the drum brake 1 from FIG. 1 with an opening
- the opening 111 has a tubular connection 114 onto which a suction cup 113 is attached.
- the suction device 113 leads via a suction line 115 to an intake tract 116 of an internal combustion engine 117 of the motor vehicle.
- the suction line 115 extends into the bottom area of the pocket 9.
- the connection 114 has a pipe socket 119 for permanent fixation of the suction line 115. Otherwise, the embodiment is designed as that from FIG.
- FIG. 5 shows a further embodiment of the lower part of the drum brake 1 from FIG. 1 with an opening 211.
- the opening 211 has a tubular connection 214 for a suction device, not shown here.
- the tubular connection 214 has a pipe socket 219.
- a collecting funnel 220 protrudes into the pocket 9 constructed as in the previously described embodiments.
- the collecting funnel 220 protrudes directly in front of the friction surface 3 of the brake drum 2 and has a trough shape for collecting the brake debris.
- Figure 6 shows a sectional view through the embodiment of Figure 5 along the line VI - VI. It can be seen here that the collecting funnel 220 is arranged between two brake pads 4.
