Definitions
- the present invention relates to a drum brake of a vehicle and its associated mounting method.
- the invention aims to improve the chain assembly of drum brakes on vehicles.
- the invention also aims to facilitate the replacement of worn drum brakes.
- a drum brake includes a drum and a brake plate.
- the drum and the brake plate have a circular shape.
- the brake plate is intended to be inserted in the drum.
- a drum brake is fixed on the one hand, concentrically to a rim of at least one wheel of a vehicle via the drum.
- the drum brake is also fixed to an axle of the vehicle via the brake plate.
- the drum and the brake plate come into contact with each other via two brake shoes.
- the two brake shoes have a circular arc shape and are arranged in diametrical opposition to each other. These two segments delimit a circle of a certain diameter.
- a hand brake lever and a play take-up lever are articulated. The handbrake lever is pulled by a handbrake cable and the action of the cable is controlled by a conductor.
- the handbrake lever is intended to exert a force on each of the segments so that these segments move away from each other to come to bear against the folded periphery of the drum.
- the clearance take-up lever is intended to bring the two brake shoes closer to the periphery of the drum when the brake linings wear out.
- a brake cylinder can be installed, in some cases, at one end of the segment, at a place where the two brake segments meet. This brake cylinder is also intended to exert a force on each of the segments when the driver presses on a brake pedal, in such a way that these segments move away from one another to come to bear against the periphery of the drum.
- the mounting of the drum brake is carried out by inserting inside the drum, the brake plate which carries the two brake shoes, the handbrake lever, the play take-up lever and the brake cylinder.
- Such an assembly requires an assembly clearance of the two brake segments.
- the mounting clearance of the two brake shoes corresponds to a distance from a given point on the periphery of the drum to another corresponding point on the circle delimited by the two brake shoes, an average distance necessary to insert the two brake shoes inside the drum being of the order of 0.8 millimeters.
- the two brake shoes must undergo a spacing in order to adapt to a working clearance.
- the operating clearance corresponds to an optimal spacing of the two brake segments with respect to a diameter of the drum.
- This optimal spacing is such that it does not allow, at rest, the contact of the brake shoes with the drum. This optimal spacing must however be close enough to the folded periphery of the drum for a given braking, braking is relatively immediate.
- the operating clearance or the distance separating the external diameter of the brake shoes from the diameter of the drum is of the order of 0.3 to 0.4 millimeters.
- the friction of the linings on the periphery of the drum over time and their use can hollow out the wall of the drum. It follows the formation of a step in the wall of the drum. Due to the formation of this step and the increase in the spacing of the two brake segments by automatic and regular readjustment of the distance between the circle delimited by the brake segments and the periphery of the drum, the extraction of the two Drum brake segments may become more difficult or even impossible to achieve.
- the invention provides an assembly method such that the spacing of the two segments of brake is set at the factory before a given operating clearance.
- the chain mounting method is greatly facilitated since the operator no longer needs to perform a hydraulic adjustment to adjust the spacing of the two brake segments to the operating clearance. To switch from the mounting clearance to the operating clearance, a single operation on the handbrake is sufficient.
- the invention thus provides an assembly method for inserting the brake shoes inside the drum. with a larger mounting clearance. For this, the two brake segments are tightened against each other so that the diameter they define is reduced.
- the invention provides a disassembly process.
- the disassembly process is such that, thanks to a light present in the drum and to a stop present on the handbrake lever, the two brake segments of the drum can be extracted from the drum by tightening them. Tightening the two brake shoes means reducing the diameter of the circle they delimit.
- the subject of the invention is therefore a drum brake for a wheel of a vehicle comprising a plate, a drum, two brake segments, and a hand brake lever articulated on one of the two brake segments, characterized in what - the plate and / or the drum are provided with a light placed directly above the place where the handbrake lever is located so that it is possible to access this light by the exterior of the plate and / or of the drum for lifting and / or pulling the lever of the brake segment on which it is articulated, - the hand brake lever is provided on one of its faces intended to be opposite a brake segments of a stop cooperating with one of the two segments.
- the invention also relates to a method for mounting a drum brake, characterized in that it comprises the following steps: - the spacing of two brake segments is adjusted in the factory to an operating clearance corresponding to a drum reference,
- the handbrake lever is pulled using the handbrake cable to replace a stopper, present on the handbrake lever, against an internal rim of the segment on which this lever is articulated.
- the subject of the invention is also a method for dismantling a drum brake, characterized in that it comprises the following steps:
- a hand brake lever of this drum brake is in a position such that a stop present on this lever is wedged against an internal rim of a first brake segment of this drum brake, this lever being articulated on this first segment and then

- Figure 3 A sectional view of a drum brake according to the invention
- Figures 4a and 4b Schematic representations of the cooperation of a stop of a hand brake lever with a brake shoe according to two embodiments of the invention.
- a drum brake 1 of a vehicle wheel comprises, according to the invention, FIG. 1, a plate 2, a drum 3, two brake segments 4 and 5, and a hand brake lever 6 hinged on one of the two brake segments 4 and 5, here segment 4.
- the plate 2 has a circular shape of a certain diameter 7 and the periphery 8 of which is folded at a right angle. This plate 2 has a central hole 9 intended to receive a shaft of a wheel (not shown).
- the tray
- FIG. 1 Inside the plate 2, FIG. 1, two brake segments 4 and 5 in the form of an arc of a circle are arranged circularly one after the other. Between these two segments 4 and 5 and the periphery 8 of the plate 2 is inserted a drum 3.
- This drum 3 has a periphery 11 by means of which the drum 3 is inserted inside the plate 2.
- This drum 3 has a wall 12 rising perpendicular to a plane of the drum 3, of a certain thickness 13.
- the wall 12 of the drum 2 has an external face 14 and an internal face 15.
- the external face 14 is intended to be opposite of the periphery 8 of the plate 2.
- the internal face 15 is intended to be opposite the two segments 4 and 5.
- the drum 3 has a diameter 16 on the internal face 15 of the wall 12.
- the two flat segments 4 and 5 have an external rim 17 at a right angle and an internal rim 18.
- the rim 17 is located opposite the periphery 1 1 of the drum 3.
- On the rim 17 of each of the segments 4 and 5 is arranged a brake lining 19.
- the brake lining 19 is intended to come to press against the internal face 15 of the wall 12 of the drum 3 during braking.
- the two segments 4 and 5 define a diameter 20 on their external edge 17 such that it is less than the diameter 16 of the drum 3.
- the hand brake lever 6 and a play take-up lever 21 are respectively disposed. These levers 6 and 21 are articulated on the segments 4 and 5 respectively using pins such as that 22.
- the resulting joints 23 and 24 are arranged facing one another, at one of the ends of each of the segments 4 and 5 so that the ends opposite to those where the joints 23 are present and 24 can join when the segments pivot around the joints 23 and 24 along axes of rotation perpendicular to the plane of FIG. 1.
- This hook 25 allows the hand brake lever 6 to be pulled by a hand brake cable (not shown).
- the clearance take-up lever 21 is articulated on the segment 5.
- a device for gear for example a series of teeth, is present at the opposite end 27 of that where the lever 21 is articulated.
- This end 27 can by complementarity be embedded in an automatic adjustment device 28 comprising, for example also, - a series of teeth.
- This end 27, by means of the device 28 makes it possible to adjust the spacing of the two segments 4 and 5 relative to the diameter 16 of the drum 3 when the brake linings 19 and the wall 12 wear out.
- the two brake segments 4 and 5 are connected by a connecting rod 29.
- the connecting rod 29 makes it possible to separate the brake segments and makes it possible to keep them at a certain distance from each other corresponding to the diameter 20.
- the link 29 has at its two ends a fork (not shown). This fork is intended to straddle at each end of the link 29, the segment brake 4 and the handbrake lever 6 on one side, and the brake shoe 5 with lever 21 on the other side.
- the segments 4 and 5 have connecting rod retaining horns 29.
- the two segments 4 and 5 are also held together by return springs such as 30 located on the brake segments 4 and 5 at the location where the two joints 23 and 24 are located and at the two ends opposite the joints 23 and 24 These springs 30 force the two brake segments 4 and 5 to return to the rest position after they have been moved apart. Between the two joints 23 and 24, there is a brake cylinder
- This brake cylinder 31 is intended to hydraulically separate the two brake segments 4 and 5 from one another in order to compress the brake linings 19 against the periphery 11 of the drum 3.
- the plate 2 also includes a light 32 located towards the periphery 8 of the plate 2 and directly above the place where the handbrake lever is located 6.
- This light 32 allows, as will be seen subsequently, extract the brake shoes 4 and 5 from the drum 3.
- the light 32 is located below the hand brake lever 6 so that an operator can access from the outside of the plate 2 to lift the hand brake lever 6 of the brake segment 4 on which it is articulated.
- the drum 3 can also include or instead a light 33, FIG. 3.
- This light 33 also makes it possible to extract the worn segments 4 and 5 from the drum 3.
- This light 33 is located directly above the handbrake lever 6 so that an operator can access the outside of the drum 3 to move the handbrake lever 6 by pulling, for example with a hooked tool, the handbrake lever 6.
- Figures 1, 2a to 2c, on the hand brake lever 6 is also present a stop 34 located on one of its faces intended to be facing the brake segment 4 and between the joint 23 and the hook 25.
- This stop 34 is produced, for example, by stamping the hand brake lever 6. The stamping is carried out in such a way that part of the wall of the hand brake lever 6 is hollowed out until a recess of a certain depth is formed. This recess corresponding to the stop 34 is intended to cooperate with the segment 4.
- the stop 34 is intended to cooperate with the side of the segment 4 according to two embodiments of the invention, Figures 4a and 4b. According to a first embodiment of the invention, FIG.
- the stop 34 cooperates with the sidewall segment 4 while being in abutment against the internal rim 18 of the segment 4.
- the stop 34 cooperates with the segment 4 by being mounted in a slot 35 made in the segment 4. Inside this slot 35, the stop 34 can thus come to bear against a portion of a periphery 35.1 of the light 35.
- a radial displacement of the stop 34 from a portion of the periphery 35.1 of the light 35 to another portion of this same periphery 35.1 allows the movement of the stop 34 inside this light 35. This movement of the stop 34 inside the light 35 therefore allows the movement of the handbrake lever 6 around the articulation 23.
- the handbrake lever 6 can be positioned in two positions A and B, FIG. 1. According to position A, the handbrake lever 6 is pushed back to the outer edge 17 of segment 4 with the stop 34 placed on the segment 4, Figure 2c. In position A, the handbrake lever 6 makes it possible to tighten the two brake segments 4 and 5 one against the other and allows in this position A to decrease the diameter 20. According to position B, ie lever handbrake 6 is set on the segment
- the handbrake lever 6 can be wedged against the internal rim 18 dti segment 4 via the stop 34.
- the handbrake lever 6 can be wedged by inserting the stop 34 in the slot 35.
- the handbrake lever 6 maintains the two brake segments 4 and 5 and allows in this position B to define a diameter corresponding to the operating clearance given according to the invention.
- the insertion of the brake segments 4 and 5 into a drum 3 requires a mounting clearance 36 and an operating clearance 37 of the two brake segments 4 and 5 relative to the diameter 16 of the drum 3.
- the figure 3 shows the mounting clearance 36 and the operating clearance 37 of a drum brake 1 sectional view, according to the invention.
- the mounting clearance 36 of the drum brake according to the invention is greater than the clearance mounting 38 of a conventional drum brake.
- a conventional mounting clearance 38 corresponds to the distance separating a point from the periphery 11 of the drum 3 from a corresponding point on the circle delimited by the two brake segments 4 and 5 of diameter 20, when these two brake segments 4 and 5 are not tight against each other.
- the mounting clearance 36 corresponds to the distance separating a point of diameter 16 from the drum 3 from a corresponding point on the circle delimited by the two brake segments 4 and 5 of diameter 20 when the brake segments 4 and 5 are pressed against each other.
- the operating clearance 37 of the drum brake 1, according to the invention makes it possible, once the two brake segments 4 and 5 are inserted in the drum 6, to move the two brake segments 4 and 5 towards the periphery 11 of the drum 3 to a diameter 20 such that the two brake segments 4 and 5 do not touch the periphery 11 of the drum 3.
- the circle delimited by the two brake segments 4 and 5 must have a diameter 20 sufficiently close to the periphery 11 of the drum 3 so that braking is relatively immediate during braking.
- FIG. 3 also shows the wear of the brake linings 19, the formation of a step 39 in the wall 12 of the drum 3 and the spacing of the two brake segments at the operating clearance 37, during the use of this drum brake 1.
- the device 28 automatic adjustment allows to make up a space 41 resulting from this wear to obtain a space corresponding to the operating clearance 37.
- the linings 19 dig into the wall 12 of the drum 3 due to their friction during braking. It then creates in the wall 12 of the drum 3 a step 39. Due to the formation of this step 39 and the take-up of the space 41 resulting from the wear of the linings 19, the assembly 40 widens and does not can no longer be removed from the drum 3.
- the assembly and disassembly method makes it possible to solve this problem.
- the link 29 corresponding to an operating clearance 37, while the lever 6 is in position B and that the lever 21 is at the start of the adjustment of the clearances.
- the adjustment of the spacing of the segments 4 and 5 is achieved by this choice of the rod 29.
- This choice can be made using a template representing the shape of the drum 3.
- the hand brake lever 6 is moved from the position B to position A, Figures 1, and 2a to 2c.
- the hand brake lever 6 is lifted from the brake segment 4 on which the hand brake lever 6 is articulated, FIG. 2b. This lifting causes a separation in a direction parallel to the axes of the joints 23 and 24.
- the hand brake lever 6 is pushed using a suitable tool, for example a screwdriver 42, so that the handbrake lever 6 lifts up from the inside of the plate 2. Or from the outside of the drum 3 and through the light 33, the hand brake lever 6 is pulled using a hooked tool. The handbrake lever 6 is raised until the stop 34 is located above the segment 4, FIG. 2b. Then the handbrake lever 6 is pushed towards the external rim 17 of this same segment 4 by the interior of the drum 3, FIG. 2c. In position A and when the lever 6 is pushed to the outer edge 17, the hand brake lever 6 moves away from the fork of the link 29.
- a suitable tool for example a screwdriver 42
- the stop 34 may no longer be placed inside the light 35 or against the internal rim 18 of the segment 4.
- the segment 4 is therefore released from the light 35 and / or the stop 34 and the fork of the link 29.
- the two segments 4 and 5 can thus tighten l one against the other. This tightening allows a mounting clearance 36 greater than the mounting clearance 38 usually used.
- the disassembly process is as follows. First, the hand brake lever 6 is lifted. For this, the same steps are carried out as previously described in FIGS. 2a to 2c. Using a screwdriver 42 and the light 32, the handbrake lever 6 which is initially in position B is pushed from behind the plate 2. Or, using a hooked tool and from the light 33, the hand brake lever 6 is pulled through the light 33. In this way the stop 34 comes above the segment 4 and outside the light 35, FIG. 2b. Then push the hand brake lever 6 to the outer edge 17 of segment 4 to obtain the hand brake lever
