Definitions
- the invention relates to a method and an apparatus for determining the thickness of a brake disk
- Thickness of a brake disk of a pneumatic vehicle in particular a passenger car (PKW) or a commercial vehicle (commercial vehicle).
- Determining and checking the thickness of brake discs of a pneumatic vehicle is an important maintenance measure.
- the thickness of a brake disc is usually measured by means of a mechanical disc vernier caliper. For this purpose, it is necessary to remove the wheel assigned to the respective brake disk and to mount it again after the measurement.
- DE 102 1 1 813 A1 discloses a system for measuring the thickness of brake discs and brake pads, which is permanently installed in the vehicle.
- DE 101 56 675 A1 discloses a method in which an ultrasonic sensor is placed on the caliper to measure the thickness of the brake pad carrier and the brake pads on one side of the brake discs. For this purpose, the brake must be pressed, to which a second person is required.
- An inventive method for determining the thickness of a brake disc of a pneumatic vehicle, in particular a car or commercial vehicle comprises the steps of applying an ultrasonic measuring head to the - - Measuring brake disc, while a disc associated with the wheel is mounted on the vehicle, that is, in particular without first dismantling the wheel to be measured associated with the wheel, and performing an ultrasonic measurement to determine the thickness of the brake disc.
- the invention also includes an apparatus for determining the thickness of a brake disc of a pneumatic vehicle, in particular a passenger car or commercial vehicle, the apparatus having at least one ultrasonic measuring head which is designed to pass through an opening formed in a rim of a wheel of the vehicle is feasible to apply the ultrasonic measuring head to a brake disc of the vehicle.
- the thickness of a brake disc of a pneumatic vehicle in particular a car or commercial vehicle, can be easily and quickly performed by a single person.
- the measurement with the method according to the invention can be carried out simply on a vehicle standing on the ground; in particular, it is not necessary to drive the vehicle onto a lift and raise it.
- the sensor can be designed as a mechanical sensor, for example as a pushbutton, as an electrical sensor, for example as a conductivity sensor, or as an optical sensor, for example as a light reflection sensor.
- the ultrasonic measuring head is designed so that it detects at least one of the webs in so-called internally ventilated brake discs, which have at least two mutually parallel brake discs, which are interconnected by webs and taken into account in the determination of the thickness of the brake disc.
- internally ventilated brake discs which have at least two mutually parallel brake discs, which are interconnected by webs and taken into account in the determination of the thickness of the brake disc.
- the device additionally has at least one evaluation and / or display unit which is spatially separate from the ultrasonic measuring head and designed to evaluate and display the measurement signals provided by the ultrasonic measuring head.
- a wired data link is particularly inexpensive and reliable, a wireless data link (realized, for example, by WLAN or Bluetooth or the like) allows a particularly convenient handling of the ultrasonic probe, since the mobility and manageability of the ultrasonic probe is not limited by a data cable.
- the evaluation and / or display unit is integrated into the measuring head, whereby a one-piece measuring device is provided, which is particularly easy to handle.
- FIG. 1 shows a schematic sectional view through a wheel 10 and a brake disk 4 of a vehicle (not shown in the figure), in particular a car or LWK, on which a measurement according to the invention is carried out.
- the brake disk 4 and the wheel 10 are on a common axis or
- the brake disk 4 shown in the figure is a so-called internally ventilated brake disk 4 which has two circular brake disk plates 4a, 4b arranged parallel to one another
- the two brake disk plates 4a, 4b are interconnected by a plurality of webs 12, which extend parallel to the axis of rotation A.
- the wheel 10 is fixed by a plurality of wheel nuts 5 on the axle or hub 1 1 and has a rim 2, which is usually made of steel or aluminum, and an air-filled tire 1, which is arranged on the outer circumference of the rim 2 ,
- openings 3 are formed at a radial distance from the axis of rotation A, which also allow access to the brake disk 4 when the wheel 10 is mounted on the axle or hub.
- a cylindrically shaped ultrasonic measuring head 6 is guided in such a way that an end face 6a of the ultrasonic measuring head 6 facing the brake disk 4 is shown on a side of the ultrasonic measuring head 6 facing the right
- Brake disc plate 4a rests, so that it is possible with the help of
- Ultrasonic measuring head 6 to measure the thickness of the brake disc 4. - -
- the end face 6a of the ultrasonic measuring head 6, which faces the brake disk 4 has the largest possible area in order to detect a region of the brake disk 4 in which at least one of the webs 12 is formed.
- the diameter D of the ultrasonic measuring head 6 must be chosen so small that the ultrasonic measuring head 6 through the openings 3, which are formed in the rim 2 of the wheel 10, can be performed.
- the power supply of the ultrasonic measuring head 6 can take place via the data connection 7, or in the case of a wireless data connection 7, via a power source provided in the ultrasonic measuring head 6 (eg a rechargeable battery or a solar cell).
- a power source provided in the ultrasonic measuring head 6 eg a rechargeable battery or a solar cell.
- the cylindrical shape of the ultrasonic measuring head 6 shown in the figure is only an example.
- the rear area 6b of the ultrasonic measuring head 6 facing away from the brake disk 4 can be designed as a handle and / or holding device, in order to make it possible to mount the ultrasonic measuring head 6 - - Easy, safe and convenient to position in a suitable position on the brake disc 4 and fix if necessary.
- the evaluation device 8 can also have a storage device 15, which makes it possible to store the results of the measurements for later evaluation and / or for documentation purposes.
- the display device 9 may be designed so that it outputs an optical alarm signal when the measured thickness of the brake disk 4 falls below a predetermined limit. Alternatively or additionally, at the
- Evaluation device 8 may also be an acoustic signaling device 16 may be provided which outputs an audible warning signal in this case.
- the evaluation device 8 and the display device 9 may be designed to be mobile, in particular, the evaluation device 8 and the
- Display device 9 be integrated into the ultrasonic measuring head 6 to form a single compact device. It should be noted, however, that the dimensions of the device are chosen so that the ultrasonic measuring head 6 can continue to be guided through an opening 3 in the rim 2, to be brought into contact with the brake disc 4.
