[0002] Disc brakes are widely used in the automotive industry due to their simple structure, easy maintenance, stable braking effect, good heat dissipation, and low braking noise. As an important part of the brake system, the caliper not only has a complex external shape, but also has high dimensional and positional accuracy of the parts. In addition, its safety performance directly affects the braking performance and is related to the personal safety of the driver and passengers. Therefore, the design of the caliper is a very important part of the brake system design.

[0003] The disc brake caliper body generally includes a bow-back part at the rear end of the caliper body and a receiving cavity at the front end of the caliper body. Because the force-enhancing structure limit surface inside the caliper body is difficult to process, the traditional radial pneumatic disc brake caliper body adopts a split structure. The bow-back part of the caliper body and the receiving caliper body are connected by bolts. This split structure facilitates the processing of the internal limit surface of the caliper body.

DETAILED DESCRIPTION

[0015] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0016] The present application provides an integrated disc brake caliper body, which is described in detail below. It should be noted that the description order of the following embodiments does not limit the preferred order of the embodiments of the present application. In the following embodiments, the description of each embodiment has its own emphasis. For parts that are not described in detail in a certain embodiment, please refer to the relevant description of other embodiments.

[0017] In order to solve the technical problems of the existing split caliper body, such as the difficulty in processing, poor connection strength, and the impact on the overall rigidity and strength of the caliper body, an embodiment of the present application provides an integrated disc brake caliper body, which is described in detail below.

[0018] The brake includes a caliper body, a bracket, a pair of brake discs, a lever and a push rod assembly, etc. The push rod assembly includes a support seat, a pair of push rods, a pair of push discs, a mounting plate, an active adjustment mechanism and a passive adjustment mechanism.

[0019] The push rod is a lead screw, which is respectively connected to both sides of the support seat. The front end of the push rod passes through the mounting plate and then connects to the push plate. A return spring is arranged between the mounting plate and the support seat. The rear end of the main push rod is connected to the active adjustment mechanism, and the rear end of the slave push rod is connected to the driven adjustment mechanism. The active adjustment mechanism and the driven adjustment mechanism are connected by a chain 43 to achieve synchronous transmission. The active adjustment mechanism is used to control the rotation of the push rod relative to the support seat, thereby controlling the position of the push plate relative to the support seat, and finally controlling the braking gap of the brake.

[0020] Since the traditional caliper body is split, the active adjustment mechanism and the driven adjustment mechanism are both located inside the caliper body, that is, the main sprocket 41, the slave sprocket 42 and the chain 43 are all located inside the chamber, which makes the assembly of the brake very inconvenient.

[0021] As Figures 1 to 5 shown, an integral disc brake caliper body includes: An outer caliper body 1, in which a first chamber 11 is opened. The first chamber 11 runs through the outer caliper body 1 up and down, and the first chamber 11 is adapted to accommodate the upper end of the bracket and the brake disc; An inner caliper body 2, in which a second chamber 21 is opened. The second chamber 21 runs through the inner caliper body 2 horizontally. The outside of the second chamber 21 is integrally formed with the outer caliper body 1. The second chamber 21 is communicated with the first chamber 11. The outside port of the second chamber 21 forms a first mounting surface 27 in the first chamber 11. A plurality of first connection holes are opened on the first connection surface. A main adjustment through hole 22, a slave adjustment through hole 23, a plurality of pin holes and a second connection hole are opened on the inner side end surface of the inner caliper body 2; A connecting body 3, in which a third chamber 31 is opened. The third chamber 31 runs through the connecting body 3 horizontally. The connecting body 3 is formed together with the inner caliper body 2. The outside cavity opening of the third chamber 31 is communicated with the second chamber 21. The rear cavity opening of the third chamber 31 serves as the push rod through hole 32 of the brake, and its hole opening is upward. The port of the push rod through hole 32 forms a horizontal second mounting surface 33; After the inner side end surface of the inner caliper body 2 is connected to the connecting body 3, the remaining end surface forms a "冂" shape structure, and the main adjustment through hole 22 and the slave adjustment through hole 23 are respectively located on both sides of the connecting body 3.

[0022] A positioning pin 24 is installed in the pin hole. The positioning pin 24 is used to support the chain 43. As Figure 5 shown, the number of the positioning pins 24 is four.

[0023] As Figure 2 shown, both the first connection hole and the second connection hole are threaded holes. The push rod assembly is matched with the first mounting surface through the mounting plate, and the connecting screw passes through the mounting plate and then connects with the first connection hole, thereby fixing the mounting plate on the first mounting surface, that is, installing the push rod assembly in the inner caliper body 2.

[0024] Specifically, as an optional implementation in this embodiment, Figure 4 As shown, a pair of arc-shaped support seats 6 are provided in the second chamber 21, and the arc-shaped support seats 6 and the inner clamp body 2 are an integral structure; The two arc-shaped support seats 6 are respectively located on both sides of the outer opening of the third chamber 31; The lever of the brake is placed horizontally in the second chamber 21 and the third chamber 31 , the rear end of the lever is arranged in the third chamber 31 , the front end of the lever extends into the second chamber 21 , and the lever passes between two arc-shaped support seats 6 .

[0025] The lever is arranged horizontally, and its rear end can swing up and down under the push of the air chamber top rod, so as to push the support seat in the push rod assembly to move forward in the second chamber 21, that is, drive the push plate forward for braking, and the support seat is reset under the return spring, and the lever is also reset at the same time.

[0026] Specifically, as an optional implementation in this embodiment, Figure 1 and Figure 2 As shown, a tool feed hole 26 is provided on the side of the inner caliper body 2, and the tool feed hole 26 is located on one side of the arc-shaped bearing seat.

[0027] Through the tool hole 26, when finishing the second chamber 21 of the caliper body, the turning tool can directly enter from the tool hole 26 to process the arc-shaped support seat 6 and several other working surfaces. After the processing is completed, the tool hole 26 is sealed with a cover.

[0028] Specifically, as an optional implementation in this embodiment, Figure 4 As shown, a slot is provided on the arc-shaped support seat 6 , and the semicircular needle roller bearing is connected to the slot via a clamping block, so that the semicircular needle roller bearing is installed on the arc-shaped support seat 6 .

[0029] Semicircular needle roller bearings are existing mature products and will not be described in detail here.

[0030] Specifically, as an optional implementation in this embodiment, Figure 3 As shown, the inner end surface of the inner caliper body 2 is connected to a cover plate 5 , and the cover plate 5 is a U-shaped structure. The cover plate 5 is suitable for covering the sprocket and chain 43 .

[0031] The main sprocket 41 is part of the active adjustment mechanism, and the slave sprocket 42 is part of the driven adjustment mechanism. The active adjustment mechanism and the driven adjustment mechanism are first installed on the push rod assembly and then installed in the second chamber 21. The rear ends of the active adjustment mechanism and the driven adjustment mechanism extend from the main adjustment through hole 22 and the slave adjustment through hole 23 respectively. Then the active adjustment mechanism is connected to the main sprocket 41, and the driven adjustment mechanism is connected to the slave sprocket 42. Finally, the chain 43 is installed between the two sprockets. Since the main sprocket 41 and the slave sprocket 42 can be installed outside the caliper body, the brake assembly is more convenient.

[0032] Specifically, as an optional implementation in this embodiment, Figures 1 to 4 As shown, the height of the outer side of the inner caliper body 2 is consistent with that of the outer caliper body 1, and an inner end plate 25 is formed at the junction of the inner side of the inner caliper body 2 and the connecting body 3. The inner end plate 25 is higher than the inner caliper body 2 and the connecting body 3. A right-angle step is formed between the outer side of the inner end plate 25 and the inner caliper body 2. The inner side of the inner end plate 25 and the inner end surface of the inner caliper body 2 are in the same vertical plane, and the pin hole and the second connecting hole are opened on the inner end plate 25.

[0033] In this embodiment, the outer caliper body 1 and the inner caliper body 2 in the caliper body do not occupy too much installation space in terms of vertical height, so that the axial disc brake can be arranged on the rear axle without space problems.

[0034] The caliper body of the present invention is integrally formed to ensure the strength of the entire caliper body. Secondly, the caliper body is re-optimized and designed, and a main adjustment through hole 22, a slave adjustment through hole 23, a plurality of pin holes and a second connecting hole are opened on the rear side of the inner caliper body 2, so that the related parts of the active adjustment mechanism and the slave adjustment mechanism can be installed, and finally the cover plate 5 is used to seal it, so that the brake assembly is more convenient.
