Wherein the calculator 3 is provided in an Electronic Control Unit (ECU) of the vehicle.
In the embodiment of this application, rim plate and wheel hub 2 normal running fit, wheel hub 2 is the free rotation of rim plate relatively, and range sensor 1 installs on the rim plate, and range sensor 1 is static for wheel hub 2's rotation axis promptly, and that is to say the distance of range sensor 1 to wheel hub 2's rotation axis is the definite value. An extension line of the sensing direction of the distance measuring sensor 1 intersects with the rotation axis of the hub 2, i.e., the sensing direction of the distance measuring sensor 1 coincides with the radial direction of the hub 2. The distance of the rim of the hub 2 is monitored in real time through the distance measuring sensor 1, the sensor transmits a monitored distance signal to the calculator 3, the calculator 3 calculates the roundness of the hub 2 by using the distance signal, and the calculator 3 transmits the roundness information of the hub 2 to the display 4. The driver can judge whether the roundness of the hub 2 is within a preset range according to the roundness information on the display 4 to ensure safe driving.
As shown in FIG. 1, a brake caliper 6 is fixed on the wheel disc in the circumferential direction, a distance measuring sensor 1 is installed on the brake caliper 6, and the sensing end of the distance measuring sensor 1 is arranged towards the inner wall of the rim of the hub 2. The brake caliper 6 is used for braking the brake disc 11, the brake disc 11 is connected with the hub 2, and the brake disc 11 and the hub 2 rotate synchronously. To ranging sensor 1, brake caliper 6 does not have radial movement, and brake caliper 6 plays the supporting role, and ranging sensor 1 installs on the rim plate through brake caliper 6, need not to increase other supporting component, does not have manufacturing cost's increase, and simple to operate.
As shown in fig. 2, brake caliper 6 is equipped with first spacing groove 5 on the side towards 2 rims of wheel hub, and range sensor 1 inserts and establishes in first spacing groove 5, and range sensor 1's outer wall cooperates with the inside wall butt of first spacing groove 5. The setting of first spacing groove 5 carries out radial spacing to range sensor 1, and at the vehicle operation in-process, the position of avoiding range sensor 1 takes place radial offset to lead to the range finding deviation.
For carrying out better spacing to distance measuring sensor 1's position, make the shape phase-match of the shape of first spacing groove 5 and the shape of distance measuring sensor 1 installation department, distance measuring sensor 1's outer wall is laminated completely with the inside wall of first spacing groove 5 promptly.

The distance measuring sensor 1 may be a laser distance measuring instrument, an infrared distance measuring instrument or an ultrasonic distance measuring instrument.
As shown in fig. 1, the ranging sensor 1 is externally covered with a protective cover 7. The setting of protection casing 7 is protected range sensor 1, and at the vehicle operation in-process, it is impaired because of the striking that receives the object that splashes to avoid range sensor 1.
In order to facilitate observation of the state of the distance measuring sensor 1, the protective cover 7 may be made of a transparent material.
As shown in fig. 2, a second limit groove 8 is formed in one side face, facing the rim of the hub 2, of the brake caliper 6, the protective cover 7 is inserted into the second limit groove 8, and the outer wall of the protective cover 7 is in butt joint with the inner side wall of the second limit groove 8. 2 rim one end of wheel hub of the orientation of protection casing 7 is equipped with and passes through hole 9, and the response end that passes through hole 9 and range sensor 1 sets up relatively. The setting of second spacing groove 8 carries out radial spacing to protection casing 7, and at the vehicle operation in-process, the skew takes place for the position of avoiding leading to range sensor 1 because of the skew of protection casing 7. Through the setting of hole 9, make distance measuring sensor 1's response end not receive 7 tip's of protection casing sheltering from, make distance measuring sensor 1's monitoring more sensitive.
Further, a space is arranged between the inner wall of the protective cover 7 and the outer wall of the distance measuring sensor 1. The arrangement of the spacing space reduces the probability that the distance measuring sensor 1 is influenced by the radial offset of the protective cover 7.
As shown in fig. 4, the protective cover 7 is in a cylindrical shape, an ear plate 10 is provided at the mounting end of the protective cover 7, and the protective cover 7 is connected to the brake caliper 6 through the ear plate 10.
Further, the wheel hub roundness monitoring system also comprises an alarm. The alarm is arranged on the vehicle and is in signal connection with the calculator 3. The setting of alarm, when wheel hub 2's circularity exceeded and predetermine the limit value scope, the driver can in time be reminded to the alarm to in time renovate wheel hub 2, guarantee safe driving.
The working principle of the hub roundness monitoring system is as follows:
the roundness of the hub 2 is P, and the calibration distance between the distance measuring sensor 1 and the inner wall of the hub 2 is L s The actual distance between the distance measuring sensor 1 and the inner wall of the hub 2 measured by the distance measuring sensor 1 is L i . The hub 2 rotates for one circle, the sampling amount of the distance measuring sensor 1 is n, and the value of n is 360 generally. Wherein, the roundness limit value of the hub 2 preset in the calculator 3 is P lim 。
The calculation formula of the roundness P of the hub 2 is as follows:
mixing P with P lim The comparison is carried out to obtain a comparison result, and the calculator 3 sends the comparison result to the display 4 and the alarm. If P is<P lim And when the roundness of the hub 2 exceeds the preset limit range, the alarm sends out an alarm signal to remind a driver.
