Definitions
- the invention relates to a wheel assembly for a motor vehicle, a wheel cover and a magnet.
- Friction brakes are usually used in motor vehicles to reduce the speed. Friction brakes usually have one or more brake pads and at least one friction partner, e.g. a brake disc, on which at least one brake pad rubs.
- a brake disc can be made of cast iron, for example, while steel wool is used as a main component for the brake pads.
- ferrous brake abrasion is generated. If this brake abrasion is not collected, particles of the brake abrasion are emitted into the environment, which increases the fine dust pollution.
- this abrasion also referred to as brake dust, which can have particle sizes of around 10 nm - 10 pm, contaminates the wheel rims on which the brakes are mounted.
- EP 2 151 596 B1 discloses a device for catching and/or holding back brake dust from a brake unit, which is based on a magnetic operating principle.
- the invention is based on the object of providing an alternative device with which brake dust can be held back more efficiently.
- a wheel arrangement for a motor vehicle comprising a steel disc wheel, a disc brake and a wheel cover.
- the steel disc wheel has a rim and a wheel disc.
- the disc brake includes a brake disc and a brake caliper.
- a number of ventilation openings are guided through the wheel disk.
- At least one magnet is arranged on the wheel cover in such a way that a magnetic field is formed between an inner side of the wheel cover and the ventilation openings.
- the mostly magnetic particles of the brake pigeon are attracted by the magnet or magnets. The brake particles are deposited on the magnetic surface and are no longer released into the environment.
- the arrangement of a magnetic brake particle collection device on the wheel cover is characterized by its ease of implementation, since only one wheel cover has to be adapted for this, while no changes are required to the wheel and wheel brake.
- the magnet can be designed as a one-piece magnet ring which is arranged coaxially to an axis of rotation of the steel disk wheel on the wheel cover.
- the radii of such a magnetic ring can easily be adapted to the distance between the ventilation openings and the axis of rotation of the steel disc wheel and to the respective diameter of the ventilation openings.
- the magnetic ring and the ventilation openings are thus self-adjusting to one another when the wheel cover is installed on an outside of the steel disc wheel.
- the magnet or magnets can be cast in a plastic body of the wheel cover.
- a one-piece wheel cover with a cast-in magnet enables easy cleaning, which can be done with a high-pressure cleaner, for example.
- the magnet or magnets can be releasably connected to the wheel cover via mechanical connecting elements.
- the mechanical connecting elements can be designed, for example, as a clip connection, as a Velcro connection or as a bayonet-like mechanical connecting device.
- the magnet or magnets can be exchanged or cleaned independently of the wheel cover.
- the magnet or magnets can be glued to an inner side of the wheel cover.
- the magnet or magnets can be designed as an adhesive magnetic tape that can be attached to the inside of the wheel cover with self-adhesive.
- the wheel cover can be a closed wheel cover.
- a ventilation of a respective wheel brake can be used
- the openings in the wheel covers provided for this purpose can be dispensed with, since the brake energy recovery (recuperation) produces less waste heat when braking.
- a closed wheel cover is therefore to be understood as meaning a wheel cover which has at least no unsealed openings between its inner and outer side. The steel disc wheel is thus fluidically closed on the outside by the closed wheel cover.
- the closed wheel covers reduce air turbulence, so that the range of electric vehicles increases. It is also advantageous that due to the lower flow rate inside the rim, less moisture and protection can reach the brake disc and brake caliper. This leads to less corrosion, so that brake noise is reduced.
- the magnet or magnets can be arranged on or within a number of openings in the wheel cover.
- openings in such an open wheel cover air can flow through the steel disc wheel, which enables cooling of the wheel brake.
- the magnets arranged on or inside the openings can attract and trap the brake particles that are created in the air flow through the steel disc wheel.
- the object is achieved by a wheel cover for a wheel assembly as described above.
- At least one magnet is or can be arranged on the wheel cover in such a way that a magnetic field can be aligned with a number of ventilation openings of a steel disk wheel.
- a magnet can be designed as a one-piece magnetic ring which is or can be aligned coaxially to a central axis of the wheel cover.
- the central axis of the wheel cover corresponds to the axis of rotation of the steel disc wheel when the wheel cover is attached to an outside of the steel disc wheel.
- At least one magnet in a plastic body Wheel cover to be cast.
- a number of mechanical connecting elements which are designed for the detachable attachment of at least one magnet, can be arranged on an inner side of the wheel cover.
- an adhesive surface for adhesive attachment of at least one magnet can be arranged on an inside of the wheel cover.
- the object is achieved by a magnet for attachment to a wheel cover according to one of the aspects described above.
- FIG. 1 shows a cross section through a wheel arrangement according to the invention
- FIG. 2 shows a first alternative of a wheel arrangement according to the invention
- FIG. 3 shows a second alternative of a wheel arrangement according to the invention
- Figure 4 shows a prior art wheel assembly
- FIG. 5 shows a third alternative of a wheel arrangement according to the invention.
- FIG. 1 shows a cross section through a wheel assembly 1 for a motor vehicle, which includes a steel disc wheel 10 with a rim 11 and a wheel disc 12 .
- a disc brake 20 On a radial inner side of the steel disc wheel 10, a disc brake 20 is arranged. A wheel cover 30 is mounted on a radially outer side of the steel disk wheel 10 .
- the disc brake 20 has a brake disc 21 and a brake caliper 22 in which a pair of brake pads 23 are arranged in a movable, controllable manner.
- the brake pads 23 contain steel wool as an essential material component.
- the brake disc 21 is made of cast iron and is centered on the wheel disc 12 by means of a hub bore. The brake disc can be screwed to the wheel disc 12 of the steel disc wheel 10 via a number of wheel nuts, which are not shown in the figure.
- a number of ventilation openings 13 are guided through the wheel disc 12 and are arranged at a distance from an axis of rotation of the steel disc wheel 10 in radia ler direction with a uniform radius. Furthermore, the ventilation openings 13 are placed in the wheel disc 12 in a circumferentially spaced-apart manner.
- the brake pads 23 are pressed against the friction ring 24 of the brake disk 21 by means of an actuator in the brake caliper 22 . Friction between the brake pads 23 and the friction ring 24 produces ferrous brake particles 50 which flow at least partially through the ventilation openings 13 into an intermediate space between the wheel disc 12 and the wheel cover 30 .
- a magnet 31 is arranged on the wheel cover 30 in such a way that a magnetic field 40 is formed between an inside of the wheel cover 30 and the ventilation openings 13 of the wheel disc 12 .
- the magnetic braking particles 50 that have flowed through the ventilation openings 13 are attracted by the magnet 31 .
- the magnetic brake particles 50 generated during the braking process remain in or under the wheel cover 30 and do not escape into the environment.
- the magnet 31 is ring-shaped in the present example, with the radii of such a magnetic ring being adapted to the distance between the ventilation openings 13 and the axis of rotation of the steel disk wheel 10 and to the respective diameter of the ventilation openings 31 .
- the magnetic ring can be glued to the inside of the wheel cover 30, for example.
- the ring-shaped magnet 31 can be designed as an adhesive magnetic tape.
- a nut-shaped adhesive surface for receiving the magnetic ring in the wheel cover 30 can be provided as an assembly or centering aid.
- FIG. 2 shows a first alternative exemplary embodiment of a wheel assembly 1 according to the invention and a corresponding wheel cover 30.
- a ringförmi ger magnet 31 is cast in a plastic body of the wheel cover 30 .
- Such a one-piece design of wheel cover 30 and magnet 31 enables simple service, since cleaning can be carried out using a high-pressure cleaner, for example.
- a preferably ring-shaped magnet 31 can alternatively also be detachably connected to the wheel cover 30 by means of a clip connection 32 .
- the magnet 31 can be replaced independently of the wheel cover 30, for example when its brake dust collection capacity is exhausted.
- the outlined clip connection 32 other common mechanical locking conditions can be provided for a detachable connection.
- the Radab covers 30 shown in Figures 1 to 3 can therefore preferably have a closed shape. This means that the openings 32 in the wheel cover 30 shown in FIG. 4, which are common in conventionally powered motor vehicles and communicate fluidically with the ventilation openings 13 of the wheel disc 12, can be dispensed with.
- FIG. 5 shows that a corresponding arrangement of magnets 31 for collecting magnetic brake particles 50 can also be used in conjunction with an open, i.e. ventilated, wheel cover 30.
- one or more magnets 31 are suitably arranged on or in the openings 32 of a corresponding wheel cover 30 .
