Description

Technical Field

[0001] The utility model relates to the field of brake calipers, in particular to an EMB brake caliper capable of improving the connection stability of a power source. Background Art

[0002] Currently, with the development trend and advancement of electronic technology, modern braking systems tend to integrate more advanced functions, such as ABS (anti-lock braking system), EBS (electronically controlled braking system), and BAS (electronic brake assist system). These systems require more electronic control units and sensors, and larger power sources to provide stronger braking force and more stable performance. The increased functional integration has led to a gradual increase in the size of the power sources in driving and parking brakes. In most current EMB calipers, the power source and the caliper body are usually connected with multiple bolts. This connection method results in uneven force between the power source and the caliper body. Uneven force may generate additional noise and vibration during braking, affecting the driving experience and even risking structural damage. At the same time, the difficulty of aligning the bolts between the power source and the caliper body each time affects installation efficiency and structural stability. Summary of the Invention

[0003] The utility model aims to solve the shortcomings of the existing technology and provides an EMB brake caliper with improved power source connection stability, so that the connection between the power source and the caliper body has the advantages of uniform force, stable and reliable connection structure, simple and efficient installation and operation.

[0004] To solve the above technical problems, the present invention is solved by the following technical solutions:

[0005] An EMB brake caliper with improved power source connection stability comprises a caliper assembly comprising a power source and a caliper body. The power source is provided with a connecting step, and the caliper body is provided with a mounting ring that cooperates with the connecting step, the mounting ring being adapted for insertion and installation. The upper end surface of the mounting ring and the lower end surface of the connecting step are circumferentially provided with a plurality of mounting connection components. Each mounting connection component comprises a claw and a groove, each claw corresponding to a groove. The claw can vertically extend into the groove and lock the mounting connection component by relative circumferential rotation between the two. The mounting ring and the connecting step are each provided with radially outward mounting ears, which are locked together by bolts. The coordination of the claws and grooves creates contact surfaces between the power source and the caliper body in multiple directions: vertically, horizontally, circumferentially, and inwardly and outwardly. This improves force uniformity between the power source and the caliper body, preventing uneven force from affecting the driving experience or even damaging the caliper. Furthermore, this installation method makes the connection between the power source and the caliper body convenient, stable, and quick.

[0006] Preferably, the claw has a vertical extension portion and a transverse limiting portion, and the transverse limiting portion is formed by bending the end of the vertical extension portion inward or outward.

[0007] Preferably, the groove includes a first cavity for the claw to extend vertically into and a second cavity for locking with the lateral limit portion. The second cavity is formed by extending the first cavity in a clockwise or counterclockwise direction, and the cavity height of the second cavity is narrower than the cavity height of the first cavity.

[0008] Preferably, a limit block is provided above the second cavity for clamping the lateral limit portion. When the power source and the mounting ring are installed through relative circumferential rotation, the limit block is provided on the side of the vertical extension portion extending from the lateral limit portion.

[0009] Preferably, the claw is arranged on the lower end surface of the connecting step of the power source, the vertical extension portion extends downward from the bottom of the connecting step, the groove is arranged on the top of the mounting ring, and the claw can extend vertically into the first cavity.

[0010] Preferably, the transverse limiting portion is located at the bottom of the vertically extending portion, and extends toward the center of the connecting step or away from the center of the connecting step.

[0011] Preferably, the caliper assembly further comprises a bracket, on which a friction plate assembly is mounted via a bracket spring, and the caliper body and the bracket are connected via a sliding shaft.

[0012] Preferably, the outer surface shapes of the connecting step and the mounting ring match each other. The connecting step and the mounting ring cooperate with each other to make the outer surfaces of the power source and the caliper flush after installation, making the appearance of the caliper more beautiful.

[0013] Preferably, the mounting ring and the mounting ears of the connecting step are provided with coaxial bolt holes.

[0014] The utility model has significant technical effects due to the adoption of the above technical solutions:

[0015] 1. The power source and the caliper body are connected with a buckle-like structure, and then stopped by bolts. Due to the coordination between the claws and the grooves, the claws can be positioned by simply inserting them into the grooves and rotating them. Compared with the traditional method of aligning the bolt holes, the connection method is simple and convenient, and the installation efficiency is significantly improved.

[0016] 2. Since the limiting surfaces between the claws and the grooves are fully fitted, the vertical limit is fully matched and the circumferential limit is one-way. After the auxiliary bolts fix the mounting ears, the circumferential limit is achieved to prevent rotation, which can make the connection between the power source and the caliper evenly stressed. When the EMB caliper assembly is working, the connection structure between the two is guaranteed to be stable and reliable.

[0017] 3. It solves the drawbacks of the traditional caliper body and power source installation method, and effectively achieves position accuracy and stability during the installation process of the power source and caliper through the cooperation of the groove and the claw.

[0028] The present invention is described in further detail below with reference to the accompanying drawings and embodiments.

[0029] Example 1

[0030] An EMB brake caliper that improves the stability of power source connection, such as Figure 1-2As shown, the caliper assembly 1 includes a power source 11 and a caliper body 12. The power source 11 is provided with a connecting step 111. The caliper body 12 is provided with a mounting ring 121 that cooperates with the connecting step 111. The mounting ring 121 is for the power source 11 to be inserted into and installed.

[0031] The upper end surface of the mounting ring 121 and the lower end surface of the connecting step 111 are circumferentially provided with a plurality of mounting connection components. Each mounting connection component includes a claw 13 and a groove 14. The positions of each claw 13 and the groove 14 correspond one to one. The claw 13 can vertically extend into the groove 14 and the mounting connection components are locked by relative circumferential rotation between the claw 13 and the groove 14.

[0032] The mounting ring 121 and the connecting step 111 are respectively provided with mounting ears 19 radially outward, and the upper and lower mounting ears 19 are locked by bolts 191 .

[0033] The claw 13 has a vertical extension portion 131 and a transverse limiting portion 132 . The transverse limiting portion 132 is formed by bending the end of the vertical extension portion 131 inward or outward.

[0034] The groove 14 includes a first cavity 141 for the claw 13 to extend vertically into and a second cavity 142 for locking with the lateral limit portion 132. The second cavity 142 is formed by extending the first cavity 141 in a clockwise or counterclockwise direction. The cavity height of the second cavity 142 is narrower than the cavity height of the first cavity 141.

[0035] A stopper 143 is positioned above the second cavity 142 to engage the transverse stopper 132. When the power source 11 and the mounting ring 121 are mounted via relative circumferential rotation, the stopper 143 is positioned on the side where the transverse stopper 132 extends beyond the vertical extension 131. The stopper 143 cooperates with the bottom wall of the groove 14 to provide upper and lower limits for the transverse stopper 132, maintaining it at that height during sliding. The wall at the end of the second cavity 142 limits the horizontal position of the transverse stopper 132, ensuring precise positioning. The auxiliary mounting lugs are secured with bolts to provide circumferential positioning.

[0036] In this embodiment, Figure 3-5 As shown, the lateral limit portion 132 is formed by bending the end of the vertical extension portion 131 outward, and the limit block 143 above the groove 14 is arranged on the outside relative to the mounting ring 121. The vertical extension portion 131 can slide from the inside of the limit block 143 when rotating.

[0037] The claw 13 is arranged on the lower end surface of the connecting step 111 of the power source 11 , the vertical extension portion 131 extends downward from the bottom of the connecting step 111 , the groove 14 is arranged on the top of the mounting ring 121 , and the claw 13 can extend vertically into the first cavity 141 .

[0038] The transverse limiting portion 132 is located at the bottom of the vertical extending portion 131 and extends toward the center of the connecting step 111 or away from the connecting step 111 .

[0039] like Figure 2 As shown, the caliper assembly 1 further includes a bracket 17 , on which the friction plate assembly 15 is mounted via a bracket spring 16 , and the caliper body 12 and the bracket 17 are connected via a sliding shaft 18 .

[0040] The outer surface shapes of the connecting step 111 and the mounting ring 121 match each other. The connecting step 111 and the mounting ring 121 are connected to each other, so that after the power source and the caliper body are installed, their outer surfaces are flush, making the appearance of the caliper more beautiful.

[0041] The mounting ring 121 and the mounting ears 19 of the connecting step 111 are provided with coaxial bolt holes. The bolt connection method is the simplest fixed connection method. The bolts pass through the upper and lower coaxial bolt holes to connect and fix, realizing circumferential fixation between the two mounting ears and playing a role in preventing rotation.

[0042] Installation steps between the clamp body and the power source:

[0043] 1. Align the two or more claws 13 of the power source with the two or more grooves 14 of the caliper body one by one, and then insert the claws 13 so that they extend vertically into the first cavity 141;

[0044] 2. After insertion, Figure 6 As shown, the power source is rotated a certain number of degrees so that the lateral limit portion 132 enters the second cavity 142 until it is stuck by the cavity wall of the second cavity 142, thereby completing the snap connection;

[0045] 3. Finally, align the upper and lower mounting ears and secure them with bolts 191. The bolts act as a stop during installation to prevent the relative rotation of the two and prevent them from falling off.

[0046] Example 2

[0047] The structure of this embodiment is roughly the same as that of embodiment 1, except that Figure 7-8 As shown, the lateral limit portion 132 is formed by bending the end of the vertical extension portion 131 inward, and the limit block 143 above the groove 14 is arranged on the inner side relative to the mounting ring 121. The vertical extension portion 131 can slide from the outside of the limit block 143 when rotating.

[0048] Installation steps of the clamp body and power source:

[0049] 1. Align the two or more claws 13 of the power source with the caliper body and the two or more grooves 14 of the caliper body one by one, and then insert the claws 13 so that they extend vertically into the first cavity 141;

[0050] 2. After insertion, Figure 9 As shown, the power source is rotated a certain number of degrees so that the lateral limit portion 132 enters the second cavity 142 until it is stuck by the cavity wall of the second cavity 142, thereby completing the snap connection;

[0051] 3. Finally, align the upper and lower mounting ears and secure them with bolts 191. The bolts act as a stop during installation to prevent the relative rotation of the two and prevent them from falling off.
