[0033] Reference below Figure 1-Figure 5 A brake caliper 100 according to an embodiment of the present invention is described.

[0034] like Figure 1-Figure 5 As shown, the brake caliper 100 according to the embodiment of the utility model includes: a caliper body 10 and a bracket 20 .

[0035] The caliper body 10 is provided with a driving member, and the caliper body 10 is provided with a driving member and a sealing ring 12. The sealing ring 12 is located between the caliper body 10 and the driving member, and the sealing ring 12 is interference fit in the driving member bracket 20 and connected to the caliper body 10. A clamping member 21 is movably connected to the bracket 20, and the driving member is suitable for driving the clamping member 21.

[0036] For example, when the bracket 20 is connected to the caliper body 10, the two are connected by bolts and the caliper body 10 can move to a certain extent relative to the bracket 20, that is, the brake caliper 100 in this embodiment is a floating caliper, which makes it easier for the driving member to drive the clamping member 21 to clamp the brake disc. At the same time, the driving member can be driven by hydraulics, so that the driving force generated is relatively large and the driving member will not be affected by the friction resistance generated by the sealing ring 12 when driving the clamping member 21 to brake, so that the clamping member 21 can respond in time and clamp the brake disc, ensuring that the brake caliper 100 will not experience braking delays. At the same time, when the braking is completed, the driving member is no longer driven by hydraulics at this moment, and the friction resistance encountered by the driving member will become a booster for the driving member to return to its position. At the same time, the driving member will also drive the clamping member 21 to move together, so that the clamping member 21 can be separated from the brake disc as soon as possible, thereby making the drag torque of the brake caliper 100 smaller.

[0037] Therefore, after the caliper body 10 and the bracket 20 are connected, the driving member on the caliper body 10 can contact the clamping member 21 when moving, so as to drive the clamping member 21. In this way, the clamping member 21 can clamp the brake disc under the drive of the driving member to brake. At the same time, the sealing ring 12 has an interference fit with the driving member. In this way, when the driving member moves relative to the caliper body 10, the sealing ring 12 can generate a certain friction resistance to the driving member. Therefore, after the driving force of the driving member disappears, the friction resistance can enable the driving member to drive the clamping member 21 to fall off the contact with the brake disc faster, thereby reducing the drag torque of the brake caliper 100.

[0038] According to the brake caliper 100 of the embodiment of the utility model, the driving member on the caliper body 10 can drive the clamping member 21 to clamp the brake disc to complete braking. When the driving member moves, the sealing ring 12 will generate friction resistance to the driving member, and when the driving force of the driving member disappears, the friction resistance will drive the driving member to return to its position. At the same time, the driving member will also drive the clamping member 21 so that the clamping member 21 will be separated from the brake disc faster, thereby reducing the drag torque of the brake caliper 100 and increasing the cruising range of the new energy vehicle 1000.

[0039] In some embodiments, the sealing ring 12 is disposed on the caliper body 10 and is interference fit with the driving member, and the interference amount d satisfies 0.2 mm≤d≤0.4 mm.

[0040] For example, the interference amount d can be d=0.2mm, or d=0.3mm, or d=0.4mm. Preferably, d=0.3mm, so that the interference amount between the sealing ring 12 and the driving member is larger, thereby the pressure on the driving member is also greater, and the friction resistance generated by the sealing ring 12 on the driving member is also greater. This can make the driving member return faster, thereby reducing the drag torque of the brake caliper 100.

[0041] Therefore, after the sealing ring 12 is set on the caliper body 10, the interference fit between the sealing ring 12 and the driving member is larger, so that the pressure on the driving member and the friction resistance are larger, so that the driving member returns faster, thereby reducing the drag torque of the brake caliper 100.

[0042] In some embodiments, the surface roughness of the sealing ring 12 is Ra, and Ra satisfies 2<Ra<3.2.

[0043] For example, the surface roughness Ra can be Ra=2.4, or Ra=2.6, or Ra=3. Preferably, in the present embodiment, Ra=2.6, so that the friction coefficient of the sealing ring 12 will be larger, thereby making the friction resistance generated by the sealing ring 12 larger, so that the friction resistance can drive the driving member to return to its position faster, thereby making the clamping member 21 disengage from the brake disc faster, thereby reducing the drag torque of the brake caliper 100.

[0044] Therefore, the higher surface roughness of the sealing ring 12 makes the friction coefficient of the sealing ring 12 larger, so that the sealing ring 12 can generate greater friction resistance, so that the driving member returns faster, thereby reducing the drag torque of the brake caliper 100.

[0045] In some embodiments, Figure 1-Figure 2 As shown, the driving member is configured as a piston 13 , and the caliper body 10 has a pressure chamber 15 , in which the piston 13 is movably disposed.

[0046] For example, the driving member is constructed as a piston 13 and the piston 13 is sleeved in the pressure chamber 15 of the caliper body 10. At the same time, the caliper body 10 pushes the piston 13 by injecting hydraulic oil into the pressure chamber 15, so that the piston 13 can move in the pressure chamber 15, and then the piston 13 can move relative to the caliper body 10. In this way, the piston 13 can have a larger torque when it moves relative to the caliper body 10 by hydraulically driving the piston 13, so that the piston 13 can have a good braking effect when driving the clamping member 21 to clamp the brake disc.

[0047] Among them, the sealing ring 12 can make the pressure chamber 15 have good sealing performance, so that when the piston 13 is braking, the hydraulic oil enters the pressure chamber 15 and pushes the piston 13 to move to achieve braking. When the piston 13 stops braking, the hydraulic oil will be extracted from the pressure chamber 15, so that negative pressure will be generated in the pressure chamber 15 and act on the piston 13 so that the piston 13 can return to its original position faster, thereby further reducing the drag torque of the brake caliper 100.

[0048] Therefore, when the driving member is constructed as a piston 13, the structure of the driving member is relatively simple, which is convenient for subsequent maintenance. At the same time, the piston 13 is driven to brake under the action of the hydraulic oil in the pressure chamber 15, so that the piston 13 can generate a large torque when driving the clamping member 21, so that the clamping member 21 can have a good braking effect when clamping the brake disc for braking.

[0049] In some embodiments, Figure 1-Figure 4 As shown, the clamping member 21 includes a first brake block 221 and a second brake block 223 , the driving member is dynamically connected to the first brake block 221 and / or the second brake block 223 , and the first brake block 221 and the second brake block 223 define a braking space 23 .

[0050] For example, the first brake block 221 and the second brake block 223 are spaced apart when they are arranged on the bracket 20, so that the first brake block 221 and the second brake block 223 define a braking space 23, and the brake disc portion extends into the braking space 23, so that the first brake block 221 and the second brake block 223 can clamp the brake disc under the drive of the driving member to achieve braking.

[0051] Furthermore, the driving member can be dynamically connected to the first brake pad 221, or the driving member can be dynamically connected to the second brake pad 223, or the driving member can be dynamically connected to both the first brake pad 221 and the second brake pad 223. Preferably, the driving member is dynamically connected to the first brake pad 221 and the first brake pad 221 is on the side close to the driving member, so that the force transmission path of the driving member is shorter when driving the first brake pad 221 to move, thereby reducing the lost force and further improving the braking effect of the brake caliper 100.

[0052] Among them, the first brake block 221 is dynamically connected to the driving member, and the second brake block 223 is connected to the caliper body 10. In this way, the driving member drives the caliper body 10 to move after driving the first brake block 221 to abut against the brake disc. At this time, the caliper body 10 drives the second brake block 223 to abut against the brake disc to achieve a better braking effect.

[0053] Thus, the driving member achieves braking by driving the first brake block 221 close to itself to abut against the brake disc, and the caliper body 10 drives the second brake block 223 to abut against the brake disc, so that the brake disc is clamped by the first brake block 221 and the second brake block 223 for braking, which can achieve better braking effect. At the same time, the driving member is only connected to the first brake block 221, so that the force transmission path of the driving force is shorter, thereby reducing the force loss, thereby achieving better braking effect. At the same time, the driving member is only connected to the first brake block 221 and occupies less space, so that there can be more space in the wheel to set the remaining parts of the vehicle 1000.

[0054] In some embodiments, Figure 1-Figure 4 As shown, a mounting cavity 14 is formed on the side of the piston 13 facing the bracket 20 , and a clamping piece 222 is provided on the side of the first brake block 221 facing the piston 13 , and the first brake block 221 is clamped and matched with the piston 13 .

[0055] For example, the clamping member 222 can be constructed as a two-claw spring, so that when the first brake block 221 is connected to the piston 13, the two-claw spring is clamped into the mounting cavity 14 of the piston 13, so that the first brake block 221 is easier to clamp with the piston 13 and the piston 13 is not easy to fall off when driving the first brake block 221. At the same time, it also makes the subsequent maintenance of the brake caliper 100 more convenient

[0056] Therefore, the first brake block 221 is engaged in the installation cavity 14 of the piston 13 through the clamping piece 222, which makes it easier to connect the piston 13 and the first brake block 221, thereby improving the installation efficiency. At the same time, when the piston 13 returns, it can drive the first brake block 221 away from the brake disc. In this way, the faster the return speed of the piston 13 is, the faster the first brake block 221 can be away from the brake disc, thereby reducing the drag torque of the brake caliper 100.

[0057] In some embodiments, Figure 1-Figure 5 As shown, an elastic member 24 is disposed on the bracket 20 , and two ends of the elastic member 24 are respectively slidably matched with the first brake block 221 and the second brake block 223 .

[0058] For example, the elastic member 24 is fixedly arranged on the bracket 20, and the length direction of the elastic member 24 intersects with the length direction of the first brake block 221 and the second brake block 223, so that the two ends of the elastic member 24 can slide and cooperate with one side of the first brake block 221 and the second brake block 223 respectively, so that the first brake block 221 and the second brake block 223 will be against the elastic member 24 during the process of clamping the brake disc and the elastic force of the elastic member 24 will gradually increase, and when the piston 13 stops driving the first brake block 221, the first brake block 221 and the second brake block 223 will move away from the brake disc under the action of the elastic force.

[0059] Therefore, the elastic member 24 is fixedly arranged on the bracket 20 and the two ends of the elastic member 24 are slidably matched with one side of the first brake block 221 and the second brake block 223, so that the first brake block 221 and the second brake block 223 can be affected by the elastic force generated by the elastic member 24 during the braking process. After the braking is completed, the driving force generated by the piston 13 disappears. At this time, the first brake block 221 and the second brake block 223 will be separated from the brake disc faster under the action of the elastic force, thereby making the drag torque of the brake caliper 100 smaller.

[0060] In some embodiments, Figure 1-Figure 5 As shown, two ends of the elastic member 24 are provided with spring plates 241 , and the spring plates 241 are suitable for at least partially abutting against the first brake block 221 or the second brake block 223 .

[0061] For example, when the first brake block 221 and the second brake block 223 are not braking, only a portion of the spring 241 will contact the first brake block 221 and the second brake block 223, and the portion of the spring 241 that is not in contact with the first brake block 221 and the second brake block 223 will bend in the direction close to the first brake block 221 and the second brake block 223, so that when the first brake block 221 and the second brake block 223 are braking, the contact area of ​​the spring 241 with the first brake block 221 and the second brake block 223 will gradually increase, and the first brake block 221 and the second brake block 223 will gradually change the spring 241 from a bent state to an extended state. At this time, the elastic force on the first brake block 221 and the second brake block 223 will gradually increase, and when the belt braking is completed and the piston 13 stops driving the first brake block 221, the spring 241 will gradually reset and drive the first brake block 221 and the second brake block 223 away from the brake disc.

[0062] Therefore, when not braking, the first brake block 221 and the second brake block 223 will partially abut against the spring plate 241 to ensure that the first brake block 221 and the second brake block 223 will not move at will, and when braking, the contact area between the first brake block 221 and the second brake block 223 and the spring plate 241 gradually increases, so that the elastic force generated by the spring plate 241 is greater. In this way, after braking is completed and the driving force disappears, the elastic force generated by the spring plate 241 can make the first brake block 221 and the second brake block 223 separate from the brake disc faster, thereby making the drag torque of the brake caliper 100 smaller.

[0063] In some embodiments, Figure 1-Figure 5 As shown, two elastic members 24 are provided, and the two elastic members 24 are symmetrically arranged on the bracket 20 and are both slidably matched with the first brake block 221 and the second brake block 223 .

[0064] For example, the elastic members 24 are symmetrically arranged at the two ends of the bracket 20, so that the two elastic members 24 will be matched and connected with the first brake block 221 and the second brake block 223, that is, the two ends of the first brake block 221 and the second brake block 223 will contact the spring sheet 241 of the elastic member 24, so that the first brake block 221 and the second brake block 223 will be subjected to a greater elastic force after braking is completed, so that the first brake block 221 and the second brake block 223 will be able to detach from the brake disc more quickly.

[0065] Therefore, the first brake block 221 and the second brake block 223 are subjected to a greater elastic force when completing braking, so that when the driving force disappears, the first brake block 221 and the second brake block 223 will be faster when leaving the brake disc, thereby reducing the drag torque of the vehicle 1000.

[0066] The utility model also provides a vehicle 1000 .

[0067] like Figure 6 As shown, a vehicle 1000 according to an embodiment of the present utility model comprises the brake caliper 100 in the above embodiment.

[0068] According to the vehicle 1000 of the embodiment of the utility model, in the brake caliper 100 thereon, the driving member on the caliper body 10 can drive the clamping member 21 to clamp the brake disc to complete braking, and the sealing ring 12 will generate friction resistance to the driving member when the driving member moves, and when the driving force of the driving member disappears, the friction resistance will drive the driving member to return to its position, and at the same time, the driving member will also drive the clamping member 21 so that the clamping member 21 is separated from the brake disc faster, thereby reducing the drag torque of the brake caliper 100 and increasing the cruising range of the new energy vehicle 1000.
