Description

Technical Field

[0001] This utility model relates to the field of wheel-side brake technology, and in particular to an internal sprocket wheel-side brake that is easy to maintain. Background Technology

[0002] Wheel-side brakes include disc brakes and drum brakes. Disc brakes are commonly used for braking sprockets. The rotating element in the friction pair of a disc brake is a metal disc that works on its end face, called the brake disc. The friction elements clamp the brake disc from both sides to generate braking. The fixed elements have various structural forms. Generally, disc brakes can be divided into two categories: caliper disc brakes and full disc brakes. The friction elements include brake pads, which are wear parts and require regular maintenance and replacement.

[0003] The existing technology has the following problems: the maintenance and replacement of brake pads is relatively cumbersome and requires workers to use tools to complete the replacement and maintenance of brake pads, resulting in low maintenance efficiency and poor practicality of the brake. To address these issues, we propose an easy-to-maintain inner sprocket side brake. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide an easy-to-maintain inner sprocket wheel side brake.

[0005] The present invention solves its technical problem through the following technical solution: it includes a mounting bracket, the side wall of which is fixed with a mounting frame by bolts, the inner wall of which is provided with a mounting mechanism, the mounting mechanism including a mounting shaft, the mounting shaft being rotatably connected to the inner wall of the mounting bracket, a brake disc being fixed to the outer side of the mounting shaft, a driving mechanism being provided on one side of the mounting frame, and a braking mechanism being provided on the inner wall of the driving mechanism.

[0006] The braking mechanism includes a mounting base disposed on the inner wall of the drive mechanism. Multiple positioning grooves are provided on one side of the mounting base. A mounting plate is slidably connected to the side wall of the mounting base. Multiple inserts are fixed to one side of the mounting plate, and the inserts are slidably connected to the positioning grooves. A slot is provided on one side of each insert. A buckle is slidably connected to the inner wall of the mounting base. A spring is fixed to one side of the buckle, and an unlocking pull block is fixed to the outer side of the buckle. A brake pad is fixed to the side wall of the mounting plate.

[0007] As a further improvement of this utility model, a slot is provided on the outer side of the mounting bracket.

[0008] As a further improvement of this utility model: a fastening nut is provided at the end of the mounting shaft, and a sprocket is fixed to one side of the brake disc by bolts.

[0009] As a further improvement of this utility model, a plurality of fastening nuts are provided on the outer side of the brake disc.

[0010] As a further embodiment of this utility model: the driving mechanism includes a special-shaped oil storage tank, which is fixed to one side of the mounting frame by bolts. An oil inlet is fixed to the top of the special-shaped oil storage tank, and multiple driving pistons are slidably connected to the inner wall of the special-shaped oil storage tank.

[0011] As a further improvement of this utility model, the inner wall of the positioning groove is fixed with an elastic block.

[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0013] 1. By incorporating a braking mechanism, brake pads can be quickly installed and removed without requiring workers to use tools, thus reducing labor intensity, improving the efficiency of brake maintenance, and consequently enhancing the practicality and functionality of the brake.

[0026] In the description of this utility model, "multiple" means two or more, unless otherwise explicitly specified.

[0027] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0028] Please see Figure 1-7This utility model provides a technical solution: it includes a mounting bracket 100, a mounting frame 120 fixed to the side wall of the mounting bracket 100 by bolts, a mounting mechanism provided on the inner wall of the mounting bracket 100, the mounting mechanism including a mounting shaft 210 and a brake disc 220, a driving mechanism provided on one side of the mounting frame 120, and a braking mechanism provided on the inner wall of the driving mechanism; the braking mechanism includes a mounting base 410, a positioning slide 420, a mounting plate 430, a plug 440, a slot 441, a buckle 450, a spring 451, an unlocking pull block 460, and a brake pad 470; by providing a braking mechanism, the brake pad 470 can be quickly installed and removed without the need for workers to use tools to disassemble and install the brake pad 470, reducing the labor intensity of workers, improving the efficiency of brake maintenance operations, and thus improving the practicality and functionality of the brake.

[0029] Specifically, the mounting bracket 100 has a slot 110 on its outer side; the slot 110 allows workers to easily pull the unlocking block 460 with their fingers to unlock and remove the brake pad 470.

[0030] Specifically, a fastening nut 211 is provided at the end of the mounting shaft 210, and a sprocket 230 is fixed to one side of the brake disc 220 by bolts; by providing a mounting mechanism, the brake disc 220 and the sprocket 230 are fixed on the mounting shaft 210, and the mounting shaft 210 is mounted on the mounting bracket 100 by the fastening nut 211, thereby realizing the installation of the sprocket 230 and the brake disc 220.

[0031] Specifically, the brake disc 220 has multiple fastening nuts 211 on its outer side; by providing ventilation grooves 221, the brake pads 470 and brake disc 220 generate a lot of heat during braking by friction, and the ventilation grooves 221 can quickly dissipate heat from the brake disc 220 to prevent the brake disc 220 from overheating and affecting the braking effect of the brake.

[0032] Specifically, the drive mechanism includes a shaped oil reservoir 310, which is fixed to one side of the mounting frame 120 by bolts. An oil inlet 320 is fixed to the top of the shaped oil reservoir 310, and multiple drive pistons 330 are slidably connected to the inner wall of the shaped oil reservoir 310. By setting the drive mechanism to drive the brake pads 470 to move, the brake pads 470 press and clamp the sprocket 230, thereby braking the rotating sprocket 230.

[0033] Specifically, an elastic block 421 is fixed to the inner wall of the positioning slide 420; by setting the elastic block 421, the insert 440 entering the positioning slide 420 is elastically supported, ensuring that the buckle 450 and the slot 441 fit tightly, thus ensuring the stability of the braking operation.

[0034] Working principle: In use, the brake disc 220 and sprocket 230 are fixed on the mounting shaft 210. The mounting shaft 210 is then installed on the mounting bracket 100 by tightening the fastening nut 211, thus installing the sprocket 230 and brake disc 220. When the brake pad 470 needs to be removed, the unlocking block 460 is pulled to move the latch 450. At this time, the latch 450 disengages from the slot 441, allowing the mounting plate 430 and brake pad 470 to be pulled out directly, achieving quick removal of the brake pad 470. When the brake pad 470 needs to be installed, the insert block 440 is aligned with the positioning groove 420 and inserted. The inclined platform structure of the latch 450 is squeezed when the insert block 440 moves. When the slot 441 moves to the latch 450 position... Under the action of spring 451, buckle 450 engages with slot 441, completing the installation of mounting plate 430 and thus enabling quick installation of brake pad 470. No worker needs to use tools to disassemble and install brake pad 470. During braking, brake fluid enters the shaped oil reservoir 310 through inlet 320. The brake fluid pushes the two sets of drive pistons 330 against the brake disc 220, thereby driving the brake pad 470 to move. The brake pad 470 clamps the sprocket 230, enabling braking of the rotating sprocket 230. During braking, the friction between brake pad 470 and brake disc 220 generates a large amount of heat, which is quickly dissipated through ventilation slot 221.

[0035] Although the present invention discloses embodiments and accompanying drawings, those skilled in the art will understand that various substitutions, variations and modifications are possible without departing from the spirit and scope of the present invention and the appended claims. Therefore, the scope of the present invention is not limited to the contents disclosed in the embodiments and accompanying drawings.
