Description

Technical Field

[0001] The utility model relates to the technical field of brake equipment, in particular to an integrated brake caliper. Background Art

[0002] The caliper disc brake is a type of disc brake. Its rotating element is a metal disc that works on the end surface, called a brake disc. The fixed element is a brake block composed of a friction block with a small working area and its metal backing plate. There are 2 to 4 brake blocks in each brake. These brake blocks and their actuators are installed in a clamp-shaped bracket spanning both sides of the brake disc, collectively called a brake caliper. The brake disc and the brake caliper together constitute a caliper disc brake.

[0003] Currently, the brake calipers in motorcycles, electric motorcycles and electric bicycles are generally of a two-section structure and are assembled and installed by bolts and nuts. Therefore, the strength is relatively low and self-twisting may occur after a long time, and even affect the safety of the driver. Utility Model Content

[0004] In order to solve the above problems, the utility model provides an integrated brake caliper, which has a high-strength structure, increases the service life, and ensures the driving safety of the driver.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] An integrated brake caliper comprises a housing and a friction plate, wherein a brake groove is concavely formed on the bottom surface of the housing, and the friction plates are located at opposite sides of the brake groove and are slidably connected to the housing so that a brake disc can be located between the two friction plates;

[0007] Oil cylinders are recessed on opposite sides of the housing, the openings of the oil cylinders face the friction plates, and pistons are arranged in the oil cylinders for driving the friction plates.

[0008] Furthermore, two ends of the shell are respectively provided with connecting pieces to mount the shell on a vehicle body.

[0009] Furthermore, a connecting seat is provided on one side of the top surface of the shell, and a connecting port is recessed in the connecting seat for connecting the brake oil pipe. Two oil circuit holes are mirror-imaged on the opposite sides of the shell, and one end of the oil circuit hole is connected to the connecting port, and the other end is connected to the corresponding oil cylinder so that the brake oil can be input into the oil cylinder.

[0010] Furthermore, a sliding opening communicating with the brake groove is provided on the top surface of the shell, a latch is fixedly provided on the sliding opening, and one end of the friction plate is embedded in the sliding opening and slidably sleeved outside the latch.

[0011] Furthermore, the latch sleeve is provided with a return spring, the return spring is located between the two friction plates, and the return spring abuts against the two friction plates respectively.

[0012] Furthermore, a fixing hole is recessed in the shell on one side of the sliding opening, and a threaded hole is penetrated through the shell on the other side of the sliding opening. One end of the latch passes through the threaded hole and the sliding opening in sequence and is embedded in the fixing hole, and the other end is threadedly connected to the threaded hole.

[0013] The beneficial effects of the utility model are:

[0014] 1. By setting the brake groove and oil cylinder in the housing, the friction plate and the piston are installed in the housing. At the same time, the housing does not need to be assembled, so that it maintains an integrated structure with a high-strength structure, increases the service life, avoids damage to the housing during driving, and ensures the driving safety of the driver.

[0015] 2. Since the connection seat is connected to the brake oil pipe, the brake oil can enter the two oil holes at the same time, and the brake oil provides pressure to the two pistons at the same time to drive the pistons to extend, so that the two friction plates can clamp the brake disc at the same time, improving the braking stability. At the same time, the oil hole of the utility model has a simple oil circuit structure, which reduces the difficulty of oil circuit maintenance.

[0016] 3. After the brake oil is recovered, the two friction plates return to their initial positions at the same time under the elastic force of the return spring to release the friction between the friction plates and the brake disc. At the same time, the return spring can provide opposite forces to the two friction plates to prevent the friction plates from accidentally contacting the brake disc and affecting the vehicle's driving.

[0024] Please also see Figures 1 to 3 An integrated brake caliper according to a preferred embodiment of the utility model comprises a housing 1 and a friction plate 2.

[0025] A brake groove 101 is concavely formed on the bottom surface of the housing 1 , and the friction plates 2 are located on opposite sides of the brake groove 101 and are slidably connected to the housing 1 so that the brake disc can be located between the two friction plates 2 .

[0026] In this embodiment, connecting members 11 are respectively provided at both ends of the shell 1 to mount the shell 1 on the vehicle body. The connecting members 11 can be fixed to the vehicle body by bolts and nuts to achieve the installation of the shell 1.

[0027] Oil cylinders 102 are recessed on opposite sides of the housing 1 . The opening of the oil cylinder 102 faces the friction plate 2 . A piston 3 is disposed in the oil cylinder 102 for driving the friction plate 2 .

[0028] By setting a brake groove 101 and an oil cylinder 102 in the housing 1, the friction plate 2 and the piston 3 are installed in the housing 1. At the same time, the housing does not need to be assembled, so it maintains an integrated structure with a high-strength structure, increases the service life, avoids damage to the housing 1 during driving, and ensures the driving safety of the driver.

[0029] like Figure 1 and Figure 2 As shown, a connecting seat 4 is provided on one side of the top surface of the shell 1, and a connecting port 401 is recessed in the connecting seat 4 for connecting the brake oil pipe. Two oil passage holes 103 are mirror-imaged on the opposite sides of the shell 1. One end of the oil passage hole 103 is connected to the connecting port 401, and the other end is connected to the corresponding oil cylinder 102, so that the brake oil can be input into the oil cylinder 102.

[0030] In this embodiment, the connecting seat 4 is arranged in the middle of one side of the top surface of the shell 1, and an inclined hole is drilled in the connecting port 401, and is drilled into the oil cylinder 102 to form an oil passage hole 103 with an inclined structure, so that the connecting port 401 and the oil cylinder 102 are connected through the oil passage hole 103, so that the brake oil can drive the piston 3 and the friction plate 2 clamps the brake disc to achieve vehicle braking.

[0031] Since the connection seat 4 is connected to the brake oil pipe, the brake oil can enter the two oil holes 103 at the same time, and the brake oil provides pressure to the two pistons 3 at the same time to drive the pistons 3 to extend, so that the two friction plates 2 can clamp the brake disc at the same time, thereby improving the braking stability. At the same time, the oil hole 103 of the utility model has a simple oil circuit structure, which reduces the difficulty of oil circuit maintenance.

[0032] like Figure 1 and Figure 3 As shown, the top surface of the housing 1 is provided with a sliding opening 104 communicating with the brake groove 101 , the sliding opening 104 is fixedly provided with a latch 5 , one end of the friction plate 2 is embedded in the sliding opening 104 and slidably sleeved outside the latch 5 .

[0033] The latch pin 5 is sleeved with a return spring 51 . The return spring 51 is located between the two friction plates 2 , and the return spring 51 abuts against the two friction plates 2 respectively.

[0034] After the brake oil is recovered, under the elastic force of the return spring 51, the two friction plates 2 return to their initial positions at the same time to release the friction between the friction plates 2 and the brake disc. At the same time, the return spring 51 can provide opposite forces to the two friction plates 2 to prevent the friction plates 2 from accidentally contacting the brake disc and affecting the driving of the vehicle.

[0035] In this embodiment, a fixing hole 501 is recessed in the shell 1 on one side of the sliding opening 104, and a threaded hole 502 is penetrated through the shell 1 on the other side of the sliding opening 104. One end of the latch 5 is embedded in the fixing hole 501 through the threaded hole 502 and the sliding opening 104 in sequence, and the other end is threadedly connected to the threaded hole 502. One end of the latch 5 is a cylindrical structure, and the other end is provided with a thread to enable one end of the latch 5 to be slidably embedded in the fixing hole 501, and the other end is threadedly penetrated into the threaded hole 502 to fix the latch 5 at the sliding opening 104.

[0036] In this embodiment, a sliding plate that slidably cooperates with the sliding opening 104 is disposed at one end of the friction plate 2 . The sliding plate passes through the sliding opening 104 and is slidably connected to the sliding opening 104 . The sliding plate is slidably sleeved outside the latch 5 .

[0037] Since the latch 5 is threadedly connected to the housing 1, the latch 5 can be removed from the housing 1 by twisting the latch 5, thereby realizing the removal of the friction plate 2. After the friction plate 2 is removed, the piston 3 and the oil circuit can be easily inspected, which effectively reduces the difficulty of maintenance.

[0038] The braking principle of the integrated brake caliper of this embodiment is:

[0039] After brake control is performed, the brake oil enters the connection port 401 through the brake oil pipe, and then enters the two oil holes 103 at the same time and is input into the oil cylinder 102, so that the piston 3 is pushed and the two friction plates 2 clamp the brake disc to brake the vehicle.

[0040] After the brake is released, under the elastic force of the return spring 51, the two friction plates 2 return to their initial positions at the same time to release the friction between the friction plates 2 and the brake disc.
