When the disc and the outer ring of the bearing are installed, the disc and the hub of the wheel can be fixed, and the disc and the wheel can synchronously rotate.
And a plurality of reinforcing ribs 1.7 distributed in a circular array are connected between the disc 1 and the cylinder 2. The purpose of setting up the strengthening rib is in order to increase the intensity between disc 1 and the cylinder 2, and a plurality of strengthening ribs 1.7 are circular array and distribute, when the wheel rotates, are favorable to the dynamic balance of wheel.
The first central channel and the second central channel are both cylindrical channels, and the axes of the first central channel, the second central channel, the disc and the cylinder are collinear. The length of the first inner cavity is larger than half of the radius of the disc. The number of the first inner cavities is more than or equal to 8; and the adjacent inner cavities are distributed at equal intervals. Through setting up a plurality of first inner chambers, and the length of first inner chamber is longer, and when the length of longer first inner chamber was favorable to the wheel to rotate, the first piston of centrifugal force compression of iron plate produced the compression of the gaseous of great volume. And set up the first inner chamber of a plurality of equidistant circular arrays that distribute to the gas volume that can compress is bigger, is favorable to improving pressure sensor's measurement accuracy.
The operation panel can control the vehicle speed limiting device to be in a first mode or a second mode, wherein in the first mode, a first electromagnetic valve is opened, and a second electromagnetic valve is closed, and in the second mode, the first electromagnetic valve is closed, and the second electromagnetic valve is opened; when the first electromagnetic valve is opened, the second electromagnetic valve is closed, the disc does not rotate and is placed parallel to the horizontal plane, the length of the elastic rope is larger than one third of the length of the first inner cavity and smaller than two thirds of the length of the first inner cavity. When the first electromagnetic valve is opened, the second electromagnetic valve is closed, the disc does not rotate and the disc is placed in parallel with the horizontal plane, the length of the elastic rope is equal to half of the length of the first inner cavity. In the second mode, the control unit controls the vibrator to vibrate when the measured value of the pressure sensor is greater than or equal to a set threshold value.
In the first mode (actually, in a non-reminding mode), the first electromagnetic valve is opened, the second electromagnetic valve is closed, the two parts of the first inner cavity separated by the first piston are actually communicated through the connecting channel, the connecting hard tube, the first central channel and the second central channel, so that the air pressure between the two parts is the same, the centrifugal force generated by the rotation of the wheel can enable the piston to move towards the circumferential direction of the disc (the purpose of arranging the iron block is to increase the centrifugal force), and the attraction of the magnet is provided, so that the first piston can be tightly attached to the end part of the first inner cavity, and in the running process of the wheel, the position of the first piston is basically fixed, and the dynamic balance of the running of the wheel is facilitated. When the wheels of the vehicle stop rotating, the centrifugal force disappears, and the first piston can reset under the tension of the elastic rope and is positioned at the approximate middle position of the first inner cavity.
In the second mode (actually be the detection mode), first solenoid valve is closed, and the second solenoid valve is opened, and the iron plate promotes first piston and outwards removes under the effect of centrifugal force to the air that first inner chamber is close to the part of disc circumferencial direction is compressed, thereby the piston of second inner chamber is compressed by atmospheric pressure, thereby the great deformation takes place for the spring, thereby pressure sensor's measuring value grow, when being greater than the settlement threshold value, the electromagnetic shaker vibrations. Because a plurality of first inner chambers are arranged, and a part of the plurality of first inner chambers, which is close to the circumference of the disc, is communicated with the second inner chamber, the gas in the first inner chambers is compressed and is transmitted to the second inner chamber to compress the second piston, so that the pressure applied to the second piston is larger, the measurement sensitivity of the pressure sensor is increased, and whether the vehicle speed exceeds a set threshold value or not is more accurate. In the second mode, the positions of the plurality of first pistons are slightly changed along with the change of the vehicle speed, so the dynamic balance is poorer than that of the first mode, and the second mode is suitable for running in places with more vehicles, such as urban areas needing speed limit running. When the vehicle exceeds the set threshold, the vibrator can remind a driver, the device can be nested and matched with the existing speed control system of the vehicle, for example, after the vibrator vibrates for 5 seconds, if the speed is still greater than the set threshold, the control unit actively reduces the speed of the vehicle until the speed of the vehicle is less than or equal to the set threshold.
While the invention has been shown and described with respect to the preferred embodiments, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the scope of the invention as defined in the following claims.
