Description

Technical Field

[0001] This utility model relates to the field of automotive brakes, specifically to an integrated disc brake caliper body. Background Technology

[0002] Disc brakes are widely used in the automotive industry due to their simple structure, ease of maintenance, stable braking performance, good heat dissipation, and low braking noise. As a crucial component of this braking system, the caliper not only has a complex external shape and requires high dimensional and positional precision, but its safety performance directly affects braking performance and is related to the personal safety of the driver and passengers. Therefore, caliper design is an extremely important part of braking system design.

[0003] Disc brake caliper bodies typically consist of a bow-shaped section at the rear of the caliper body and a receiving cavity at the front. Because the limiting surfaces of the force-amplifying structure inside the caliper body are difficult to machine, traditional radial air disc brake caliper bodies employ a split structure. The bow-shaped section and the receiving cavity are connected by bolts. This split structure facilitates the machining of the internal limiting surfaces. However, due to the high requirements for the shape and positional accuracy of caliper body parts in automotive braking systems, the traditional split structure places even greater demands on caliper body assembly and machining, increasing processing difficulty. Furthermore, the bolts pose a risk of failure, affecting the overall rigidity and strength of the caliper body. Utility Model Content

[0032] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0033] This application provides an integrated disc brake caliper body, which will be described in detail below. It should be noted that the order of description of the following embodiments is not intended to limit the preferred order of the embodiments of this application. Furthermore, in the following embodiments, the descriptions of each embodiment have their own emphasis; parts not described in detail in a certain embodiment can be referred to in the relevant descriptions of other embodiments.

[0034] To address the technical problems of existing split caliper bodies, such as high processing difficulty, poor connection strength, and impact on the overall rigidity and strength of the caliper body, an embodiment of this application provides an integrated disc brake caliper body. This is described in detail below.

[0035] The brake includes a caliper body, a bracket, a pair of brake discs, a lever, and a push rod assembly. The push rod assembly includes a support base, a pair of push rods, a pair of push discs, a mounting plate, an active adjustment mechanism, and a passive adjustment mechanism.

[0036] The push rod is a lead screw, which is connected to both sides of the support base. The front end of the push rod passes through the mounting plate and is connected to the push plate. A return spring is set between the mounting plate and the support base. The rear end of the main push rod is connected to the active adjustment mechanism, and the rear end of the push rod is connected to the driven adjustment mechanism. The active adjustment mechanism and the driven adjustment mechanism are connected by chain 43 to achieve synchronous transmission. The active adjustment mechanism is used to control the push rod to rotate relative to the support base, thereby controlling the position of the push plate relative to the support base, and finally controlling the braking clearance of the brake.

[0037] Traditional caliper bodies are split, with both the active and driven adjustment mechanisms located inside the caliper body. Specifically, the main sprocket 41, the driven sprocket 42, and the chain 43 are all located inside the chamber, which makes brake assembly very inconvenient.

[0038] like Figures 1 to 5 As shown, an integrated disc brake caliper body includes...

[0039] An outer clamp body 1, wherein a first chamber 11 is formed inside the outer clamp body 1, the first chamber 11 extends vertically through the outer clamp body 1, and the first chamber 11 is adapted to accommodate the upper end of the bracket and the brake disc;

[0040] The inner clamp body 2 has a second chamber 21 that extends laterally through it. The outer side of the second chamber 21 is integrally formed with the outer clamp body 1. The second chamber 21 is connected to the first chamber 11. The outer port of the second chamber 21 forms a first mounting surface 27 in the first chamber 11. Multiple first connecting holes are formed on the first mounting surface 27. The inner end face of the inner clamp body 2 has a main adjustment through hole 22, a slave adjustment through hole 23, multiple pin holes, and a second connecting hole.

[0041] The connecting body 3 has a third chamber 31 inside it. The third chamber 31 extends laterally through the connecting body 3. The connecting body 3 is formed together with the inner clamp body 2. The outer cavity of the third chamber 31 is connected to the second chamber 21. The rear cavity of the third chamber 31 serves as the top rod through hole 32 of the brake. Its opening faces upward. The port of the top rod through hole 32 forms a horizontal second mounting surface 33.

[0042] After the inner clamping body 2 is connected to the connecting body 3, the remaining end face of the inner clamping body 2 forms a "冂" shape structure, and the main adjustment perforation 22 and the secondary adjustment perforation 23 are respectively located on both sides of the connecting body 3.

[0043] A positioning pin 24 is installed in the pin hole, and the positioning pin 24 is used to support the chain 43. As Figure 5 shown, the number of the positioning pins 24 is four.

[0044] 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 27 through the mounting plate. After the connecting screw passes through the mounting plate, it is connected to the first connection hole, thereby fixing the mounting plate on the first mounting surface 27, that is, installing the push rod assembly in the inner clamping body 2.

[0045] Specifically, as an optional implementation manner in this embodiment, as Figure 4 shown, a pair of arc-shaped support seats 6 are arranged in the second chamber 21, and the arc-shaped support seats 6 and the inner clamping body 2 are of an integral structure;

[0046] The two arc-shaped support seats 6 are respectively located on both sides of the outer cavity opening of the third chamber 31;

[0047] The lever of the brake is horizontally placed 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 through between the two arc-shaped support seats 6.

[0048] The lever is horizontally arranged, and its rear end can swing up and down under the push of the air chamber push rod, so as to push the support seat in the push rod assembly to move forward in the second chamber 21, that is, to drive the push plate to perform braking forward. The support seat is reset under the return spring, and at the same time the lever is also reset.

[0049] Specifically, as an optional implementation manner in this embodiment, as Figure 1 and Figure 2 shown, a tool feed hole 26 is formed in the side surface of the inner clamping body 2, and the tool feed hole 26 is located on one side of the arc-shaped bearing seat.

[0050] Through the tool feed hole 26, when the second chamber 21 of the caliper body is machined to a high precision, the turning tool can directly enter from the tool feed hole 26 to process the arc-shaped support seat 6 and several other working surfaces. After the processing is completed, the tool feed hole 26 is blocked with a cover.

[0051] Specifically, as an optional implementation manner in this embodiment, as Figure 4 shown, a clamping groove is formed in the arc-shaped support seat 6, and the semi-circular needle roller bearing is connected to the clamping groove through a clamping block, so as to install the semi-circular needle roller bearing on the arc-shaped support seat 6.

[0052] Semi-circular needle roller bearings are existing mature products and will not be discussed further here.

[0053] Specifically, as an optional implementation method in this embodiment, such as Figure 3 As shown, the inner end face of the inner clamp 2 is connected to the cover plate 5, which has a U-shaped structure and is suitable for covering the sprocket and chain 43.

[0054] The main sprocket 41 is part of the active adjustment mechanism, and the driven sprocket 42 is part of the passive adjustment mechanism. The active and passive adjustment mechanisms are first installed on the push rod assembly and then installed in the second chamber 21. The rear ends of the active and passive adjustment mechanisms extend from the main adjustment through hole 22 and the driven adjustment through hole 23, respectively. Then the active adjustment mechanism is connected to the main sprocket 41, and the passive adjustment mechanism is connected to the driven sprocket 42. Finally, the chain 43 is installed between the two sprockets. Since the main sprocket 41 and the driven sprocket 42 can be installed outside the caliper body, the brake assembly is more convenient.

[0055] Specifically, as an optional implementation method in this embodiment, such as Figures 1 to 4 As shown, the outer side of the inner clamp 2 is at the same height as the outer clamp 1. An inner end plate 25 is formed at the junction of the inner side of the inner clamp 2 and the connecting body 3. The inner end plate 25 is higher than the inner clamp 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 clamp 2. The inner side of the inner end plate 25 and the inner end face of the inner clamp 2 are on the same vertical plane. The pin hole and the second connecting hole are opened on the inner end plate 25.

[0056] 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 the vertical height, thus solving the problem of no space to arrange the axial disc brake on the rear axle.

[0057] The caliper body of this utility model is integrally molded, which ensures the strength of the entire caliper body. Secondly, the caliper body is redesigned and optimized. A main adjustment through hole 22, a driven adjustment through hole 23, multiple pin holes and a second connecting hole are opened on the rear side of the inner caliper body 2, so that the relevant parts of the active adjustment mechanism and the driven adjustment mechanism can be installed. Finally, the cover plate 5 is used to seal the caliper, making the brake assembly more convenient.
