Detailed Description
Fig. 1 is a schematic structural view of a brake for a vehicle according to another embodiment of the present invention. Fig. 2 is a partial structural schematic view of a brake for a vehicle according to another embodiment of the present invention. As shown in fig. 1 and 2, the present invention provides a brake for a vehicle, which includes a plurality of friction plates 1 and at least two brake shoes 2, wherein at least one friction plate 1 is fixed on each brake shoe 2. The brake also comprises the same number of sensors 3 as the brake shoes and the same number of clamping pins 5 as the brake shoes as the controller 8. Each detent 5 is provided on each brake shoe 2. Each sensor 3 is mounted on one of the brake shoes 2, respectively, for sensing a position variation amount of the brake shoe 2.
According to the scheme of the embodiment, the position change quantity of the brake shoes 2 is sensed by arranging the sensors 3 on the brake shoes 2, and each brake shoe 2 is provided with one sensor 3, so that the abrasion of the friction plate 1 corresponding to the brake shoe 2 can be accurately determined from the brake shoes 2, and the maintenance and the replacement are convenient. Further, in the using process of a vehicle, the friction plate 1 is required to brake, when the friction plate 1 is worn, the position of the brake shoe 2 which is opened for braking is correspondingly changed, and the larger the wear degree of the friction plate 1 is, the larger the position variation of the brake shoe 2 is, so that the position of the current brake shoe 2 when the brake shoe 2 is opened for braking can be measured through the sensor 3 arranged on the brake shoe 2, the position variation is obtained, and the wear condition of the friction plate 1 is judged. Therefore, the wear condition of the friction plate 1 can be intelligently monitored in the whole process, and the reliability is high.
Continuing with fig. 1, in one embodiment, the brake further includes at least one return spring 4. Two ends of each return spring 4 are respectively connected with the clamping pins 5 on two adjacent brake shoes 2 for returning the brake shoes 2. Each locking pin 5 is correspondingly arranged on each brake shoe 2 and is used for connecting a return spring 4. In a preferred embodiment, two adjacent brake shoes 2 are provided with a clamping pin 5 at their two ends, and each clamping pin 5 is connected with one end of the same return spring 4. When the vehicle brakes, the brake shoe 2 needs to be opened to brake, and after the vehicle brakes, the brake shoe 2 is reset through the return spring 4.
As shown in fig. 1, in one embodiment, the brake further comprises a brake drum 6 and at least one cam 7. The brake drum 6 is arranged outside at least two brake shoes 2, the brake drum 6 is in contact with the friction plate 1 when the brake shoes 2 are opened, and a preset gap exists between the brake drum 6 and the friction plate 1 when the brake shoes 2 are retracted. Each cam 7 is arranged between the two brake shoes 2 and used for pushing the two brake shoes 2 to move towards two opposite sides and open so as to enable the friction plate 1 to be in contact with the brake drum 6 and further enable the brake drum 6 to stop rotating.
Optionally, in one embodiment, the brake further comprises a controller 8 connected to each sensor 3, the sensor 3 senses the position change amount when the brake shoe 2 is opened and sends the position change amount to the controller 8, and the controller 8 determines that the friction plate 1 is worn when the position change amount is larger than a preset value. The position of the current brake shoe 2 when the brake is opened can be measured through the sensor 3 arranged on the brake shoe 2 and sent to the controller 8, the controller 8 compares the current position with the initial position (the initial position is the position of the friction plate 1 after the brake shoe 2 is opened when the brake is firstly braked after the friction plate 1 is installed), and the position variation is obtained, so that the abrasion condition of the friction plate 1 is judged. There is no need to embed a chip in the friction plate 1 as in the prior art, no need to punch a hole in the brake shoe 2, and no need for complicated piping inside the brake. When the vehicle brakes, the cam 7 pushes the brake shoe 2 to rotate left and right, and the friction plate 1 on the brake shoe 2 is contacted with the brake drum 6 to generate braking force, so that the braking is realized. In this process, the locking pin 5 moves left and right with the brake shoe 2 being opened. As the friction lining 1 wears, the detent 5 is further away from the initial position when the brake shoe 2 is opened.
Optionally, the sensor 3 is nested within the bayonet 5.
As shown in fig. 2, in one embodiment, the brake further comprises an alarm 9 connected to the controller 8 for giving an alarm to remind the driver to replace the friction plate 1 when the controller 8 judges that the friction plate 1 is worn. Since the clearance between the friction plate 1 and the brake drum 6 needs to be adjusted by an automatic adjusting arm of the brake after the brake is installed, and the positions of the brake and the clamping pin 5 are continuously changed in the process, in a preferred embodiment, when the vehicle driving range is set to be more than or equal to 100km, the controller 8 marks 0 on the sensor 3. When the sensors 3 are marked with 0, under the condition of no braking signal, each position sensor 3 respectively collects 5 position point data, and the average value of the 5 points is used as the 0 point of the position sensor 3. After the reference 0, the controller 8 collects the stroke L0 of the sensor 3 moving when the driver steps on the brake pedal and generates the braking force 5 times, as the stroke of the normal brake latch 5 in the initial state.
As the friction plate 1 is worn continuously, the sensor 3 is farther from the initial 0 point position after braking each time, when the distance from the 0 point calculated by the controller 8 reaches the set value L1 of the wear alarm of the friction plate 1, the controller 8 sends a wear alarm signal of the friction plate 1 to the alarm 9, and accordingly, the alarm 9 sends an alarm to remind a driver to replace the friction plate 1.
In addition, in a preferred embodiment, after the mark 0 is marked, after each time the vehicle is powered on, the controller 8 completes judgment of a wear alarm, when the controller 8 calculates that the actual thickness of the friction plate 1 is 2 times larger than the wear alarm thickness, the wear alarm device is powered off automatically, real-time monitoring is not performed any more, and judgment is performed again after the next power on (for example, when the thickness of the friction plate 1 is 12mm, the wear alarm thickness is set to be 2mm, and the thickness of the friction plate 1 is more than or equal to 4mm, the sleep mode is entered after each power on detection). When the controller 8 calculates that the actual thickness of the friction plate 1 is 1 time larger than the wear alarm thickness and is less than or equal to 2 times, if the vehicle is not powered off, the wear alarm device is awakened once every 4 hours. When the controller 8 calculates that the actual thickness of the friction plate 1 is less than or equal to 1 time of the wear alarm thickness, the controller 8 judges the wear condition every time braking is carried out.
Further, if the distance difference between the two sensors 3 is large in the process that the controller 8 judges the position of the bayonet 5, the failure of the cam 7 or the brake shoe 2 of the brake can be prompted to remind a driver to check the brake in time.
Alternatively, at least two brake shoes 2 are distributed on the same ring, which is concentric with the brake drum 6.
Optionally, the cam 7 is substantially S-shaped. When the vehicle brakes, it rotates around the center position, and the two ends push the brake shoes 2 to open.
As shown in fig. 1, the number of brake shoes 2 is two, and two friction plates 1 are fixed to each brake shoe 2.
In particular, a vehicle includes a brake for the vehicle. The wear of the friction plate 1 in the brake can be monitored intelligently in the whole process, and an alarm can be given when the friction plate is worn to a certain extent.
Thus, it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the invention have been shown and described in detail herein, many other variations and modifications can be made, consistent with the principles of the invention, which are directly determined or derived from the disclosure herein, without departing from the spirit and scope of the invention. Accordingly, the scope of the present invention should be understood and interpreted to cover all such other variations or modifications.
