Definitions
- the present invention relates to a braking device for a vehicle which comprises a drum brake adapted to collect magnetic particles of braking dust emitted during braking of the vehicle.
- the present invention relates more particularly to such a braking device for a vehicle which comprises a drum brake comprising a first part intended to be fixed to a running gear of said vehicle and a second part forming a support for fixing a wheel of said running gear, the first part comprising a metal plate, the inner wall of which forms a support for two movable segments, each segment being provided with a brake lining, the second part comprising a drum, the inner side wall of which is adapted to form a bearing surface for the brake linings during a braking phase, the fiction of the brake linings against the drum creating magnetic particles of braking dust, the drum brake comprising magnets adapted to retain at least a part of said magnetic particles of braking dust .
- a braking device for a vehicle which comprises a drum brake comprising a first part intended to be fixed on a running gear of said vehicle and a second part forming a support for fixing a wheel of said train roller, the first part comprising a metal plate, the inner wall of which forms a support for two movable segments, each segment being provided with a brake lining, the second part comprising a drum, the lateral inner wall of which is adapted to form a surface of support for the brake linings during a braking phase, the fiction of the brake linings against the drum creating magnetic particles of braking dust, the drum brake comprising magnets adapted to retain at least a part of said magnetic particles of brake dust, such that magnets are positioned along its peripheral edge of the platter.
- a peripheral opening on the periphery of the drum brake, between the first part and the second part, is formed a peripheral opening, the magnets being positioned at the edge of said peripheral opening.
- the magnets are positioned in housings positioned outside the drum brake.
- openings are formed along the edge of the plate in correspondence of said housings for the passage of the magnetic particles of braking dust towards the magnets, preferably, the housings are separated two by two by a angular sector equal to 60 degrees, but a smaller angular sector can also be envisaged, this increases the production cost of the braking device and its weight, but this increases the quantity of magnetic particles of braking dust which are collected in the housings .
- the housings are removable, allowing them to be removed in order to remove the magnetic particles of braking dust without dismantling the drum brake.
- Such housings are preferably made of metal.
- the present invention also relates to a motor vehicle running gear comprising a braking device which comprises at least one of the preceding characteristics. It also relates to a vehicle which comprises at least one such running gear, such running gear generally constituting a rear axle of the vehicle.
- a motor vehicle running gear comprising a braking device which comprises at least one of the preceding characteristics. It also relates to a vehicle which comprises at least one such running gear, such running gear generally constituting a rear axle of the vehicle.
- FIG. 1 shows a perspective view of a brake drum according to the invention.
- FIG. 2 shows a partial perspective view of the brake drum according to the invention without the brake drum.
- FIG. 3 shows a partial perspective view of a plate of a first part of the brake drum according to the invention.
- a braking device comprising a drum brake 1 which comprises a first part 2 intended to be fixed on a running gear of said vehicle (the running gear not being shown) and a second part 3 which forms a support for fixing a wheel of said running gear (the wheel not being shown).
- the first part 2 comprises a metal plate 21 whose inner wall forms a support for two movable segments 23, each segment 23 being provided with a brake lining 24.
- the second part 3 comprises a drum 31 whose inner side wall is adapted to form a support surface for the brake linings 24 during a braking phase.
- a peripheral opening 11 Through which escapes a large part of the magnetic particles of braking dust causing magnets 4 to be positioned at the edge of this peripheral opening 11 to retain a maximum.
- the magnets 4 are positioned in housings 5 positioned outside the drum brake 1, in correspondence of openings 25 which are formed along the outer edge of the plate 21.
- the housings 5 are separated two by two by an angular sector equal to 60 degrees and are made of metal, so that the magnets 4 which are directly in contact with the metal of the housings 5, also magnetize the housings 5 and part of the plate 21 in edge of these housings 5, causing these parts of the drum brake 1 to also directly attract the magnetic particles.
- the housings 5 are removable, making it possible to remove the magnetic particles which have accumulated in each housing 5 without dismantling the drum brake 1.
