Referring to fig. 1 and 2, a caliper structure 100 of the present invention includes a bracket 10, a friction plate backing plate 20, and a piston 30. The friction plate back plate 20 comprises a first mounting part 21 and a second mounting part 22 which are opposite, and the first mounting part 21 and the second mounting part 22 are mounted on the bracket 10; the piston 30 is connected to the friction plate backing plate 20. The center of the first mounting portion 21 is connected with the center of the second mounting portion 22 to form a center line, and the center of the piston 30 is higher than the center line.
The utility model discloses in calliper structure 100 of embodiment, the central line that forms is connected with the center of second installation department 22 with the center of first installation department 21 sets to the center that is less than piston 30 for in braking process, friction disc backplate 20 produces the moment the same with the wheel direction of travel, in order to ensure that friction disc backplate 20 can not have the tendency to rotate for the wheel, thereby guarantee friction disc backplate 20's stability, and then make calliper avoid the braking low frequency noise that produces at the in-process of work. Meanwhile, the design does not need to additionally increase the structure, so the design cost is low.
Specifically, the bracket 10 may be used to support the friction plate back plate 20, and the friction plate back plate 20 may be mounted on the bracket 10 by means of snap-fit connection, welding, or the like. The first mounting portion 21 and the second mounting portion 22 may be symmetrical structures on the friction plate backing plate 20, and the first mounting portion 21 and the second mounting portion 22 may be located at both ends of the friction plate backing plate 20 and symmetrical with respect to a central axis of the friction plate backing plate 20, respectively. The first mounting portion 21 may be circular or square, but the embodiment of the present invention is not limited thereto. Similarly, the second mounting portion 22 may also be circular, square, etc., which is not limited by the embodiment of the present invention.
The piston 30 may be commercially available or custom made, and the embodiment of the present invention is not limited to a specific type of the piston 30. The piston 30 may be in the shape of a cylinder, a prism, etc., and the embodiment of the present invention is not limited thereto. The piston 30 may be connected to the friction plate backing plate 20 by welding, bolting, etc., and the piston 30 may be pressed against the friction plate backing plate 20, and further, the piston 30 may be pressed against the friction plate backing plate 20 completely.
Taking the first mounting portion 21 and the second mounting portion 22 as an example, both of which are square, the center of the first mounting portion 21 may be the geometric center of the square, and the center of the second mounting portion 22 may also be the geometric center of the square. In this case, the center line may be a line connecting the centers of the two squares.
Taking the shape of the piston 30 as a cylinder as an example, the center of the piston 30 may be the center of the end circle of the cylinder. The center of the piston 30 may be higher than the center line in the height direction of the vehicle 1000. If the center of the piston 30 is lower than the center line in the height direction of the vehicle 1000, the force direction of the friction plate back plate 20 is opposite to the force direction of the center of the piston 30 when the height direction of the vehicle 1000 is higher than the center line, so that in the braking process, the friction plate back plate 20 generates a torque opposite to the driving direction of the wheel, so that the friction plate back plate 20 has a rotation tendency relative to the wheel, the stability of the friction plate back plate 20 is affected, and the low-frequency braking noise generated in the working process of the caliper is further caused. The force-receiving direction of the friction plate back plate 20 is the direction indicated by the hollow arrow in the figure, the wheel driving direction is the direction indicated by the solid arrow above the figure, and the moment generated by the friction plate back plate 20 under the force-receiving direction is the direction indicated by the solid arrow below the figure.
Referring to fig. 1, in some embodiments, the height difference H between the center of the piston 30 and the centerline is greater than 6mm.
Therefore, the friction plate back plate 20 does not have a tendency of rotating relative to the piston 30, and the stability of the friction plate back plate 20 is ensured, so that the brake low-frequency noise generated in the working process of the caliper is reduced. If the height difference H between the center of the piston 30 and the center line is less than 6mm, under the same stress condition, the moment arm is reduced, and the moment is reduced, so that the friction plate back plate 20 generates a moment opposite to the driving direction of the wheel, and the friction plate back plate 20 has a rotation tendency relative to the wheel.
Optionally, the height difference H between the center of the piston 30 and the center line may be 6mm, 6.5mm, 7mm, etc., and the embodiment of the present invention does not limit this.

In this way, the friction plate back plate 20 can be fixed on the support 10 by the first protrusions 24 and the second protrusions 25, so that the slippage of the friction plate back plate 20 relative to the support 10 is reduced, thereby avoiding the abrasion and dragging of the friction plate back plate 20 during braking and the low-frequency noise generated during braking.
Specifically, the body 23 may be the main structural portion of the friction plate backing plate 20, and the piston 30 and the orthographic projection may all be located within the orthographic projection of the body 23. The first mounting portion 21 may be a portion of the main body 23 close to the bracket 10, the first mounting portion 21 may have a plurality of positions, the first protrusions 24 may be a plurality of positions, the plurality of first protrusions 24 may be disposed at intervals on the first mounting portion 21, and the more the first protrusions 24 are, the tighter the connection between the friction plate backing plate 20 and the bracket 10 is.
Similarly, the second mounting portion 22 may be a portion of the main body 23 close to the bracket 10, there may be a plurality of second mounting portions 22, there may be a plurality of second protrusions 25, and a plurality of second protrusions 25 may be arranged at intervals on the second mounting portion 22, and the more second protrusions 25, the tighter the connection between the friction plate back plate 20 and the bracket 10 is.
The shape of the first bump 24 and the second bump 25 may be circular, square, etc., and the embodiment of the present invention is not limited thereto.
The connection mode of first lug 24 and body 23 can be block connection, bolted connection, welding etc., and the connection mode of second lug 25 and body 23 also can be block connection, bolted connection, welding etc., the embodiment of the utility model discloses this all does not do the restriction.

The first and second mounting grooves 11 and 12 may be ship-shaped grooves, rectangular grooves, etc., and the first and second protrusions 24 and 25 are at least partially inserted into the first and second mounting grooves 11 and 12.
Referring to fig. 1, in some embodiments, the center of first bump 24 and the center of second bump 25 are located at the same height.
If the center of the first bump 24 and the center of the second bump 25 are not located at the same height, the torques applied to the first bump 24 and the second bump 25 cannot be offset, which is not favorable for the service life of the first bump 24 and the second bump 25.

Specifically, "the projection of the piston 30 on the surface in contact with the friction plate back plate 20" refers to the orthographic projection of the piston 30. The upper end 26 may be of arcuate configuration, and in this case the piston 30 is of arcuate configuration. The upper end 26 may be of square configuration, and the piston 30 is now of square configuration. The configuration of the upper end 26 ensures that the piston 30 is always located on the friction plate backing plate 20.
