In addition, without contradiction, those skilled in the art can combine and combine the different embodiments or examples described in this specification and the features of different embodiments or examples.

[0027] The following is combined with Figures 1-4 to describe the embodiments of the present utility model.

[0028] Figure 1 The structural schematic diagram of the braking system provided by the embodiment of the present utility model is illustrated. Figure 2 The partial structural schematic diagram of the braking system provided by the embodiment of the present utility model is illustrated. Refer to Figure 1 and Figure 2 According to the present utility model, a braking system provided by an embodiment of the present utility model includes a mounting assembly 100, a brake pedal assembly 200, and a brake 300. The brake pedal assembly 200 includes a rotating member 210, the rotating member 210 is rotatably arranged on the mounting assembly 100, and at least two brake pedal members 220 are arranged in parallel on the rotating member 210. A return spring 240 is arranged between the brake pedal member 220 and the mounting assembly 100; the brake 300 is in transmission connection with the rotating member 210. It should be noted that specifically, the number of the brake pedal members 220 can be two. When specifically arranged, one of the two brake pedal members 220 is arranged near the accelerator pedal, that is, near the right foot of the operator. The other of the two brake pedal members 220 is arranged near the left foot of the operator.

[0029] By arranging two brake pedal members 220 in parallel, the present utility model enables one of the two brake pedal members 220 to be controlled by the left foot of the operator and the other to be controlled by the right foot of the operator. When switching from the accelerator pedal to the brake pedal, when the right foot of the operator releases the accelerator pedal, the left foot can almost simultaneously operate the brake pedal, reducing the switching time between the two, enabling the working machine to respond to the braking command more promptly, reducing the risk of vehicle slip caused by a long switching time, and significantly improving the safety during the operation process. In addition, the traditional single-pedal braking system requires the operator's right foot to frequently switch between the accelerator pedal and the brake pedal, which easily causes foot fatigue. However, in this design scheme, by arranging the brake pedal members 220 in parallel, the burden on the operator's right foot is reduced, and the working comfort and durability are improved.

[0030] Furthermore, both of the two brake pedal members 220 of the present utility model are connected to the brake 300 through the same rotating member 210. Therefore, the two brake pedal members 220 can share one brake 300. Although the number of the brake pedal members 220 is increased, such a design enables the entire braking system to still maintain a compact structure, does not occupy too much space, and is convenient for installation and layout on the working machine. In addition, both of the two brake pedal members 220 being connected to the brake 300 through the same rotating member 210 can also make the two brake pedal members 220 more synchronous during operation, making the working machine transition more smoothly. Moreover, by arranging the return spring 240, the brake pedal assembly 200 can automatically reset after the braking is cancelled, improving the comfort of the braking operation.

[0031] In some possible embodiments, a force adjustment mechanism can be added on the basis of the return spring 240, so that the operator or maintenance personnel can adjust the elastic force of the spring according to actual needs. In this way, the return speed and strength of the pedal can be customized according to the weight, speed and braking force requirements of the working machine, improving the adaptability and flexibility of the system.

[0032] Figure 3 The structural schematic diagram of the installation component of the braking system provided by the embodiment of the present utility model is illustrated. Refer to Figure 3 , in some embodiments of the present utility model, the installation component 100 includes a bottom plate 110, at least two mounting seats 120 and a side plate 130. The mounting seats 120 are arranged at intervals on the top of the installation component 100, and the mounting seats 120 are used for mounting the rotating component 210; the side plate 130 is arranged on the bottom plate 110 and is located on one side of the two mounting seats 120. It should be noted that the number of the mounting seats 120 can also be four, with two as a group, and the two groups are arranged at intervals.

[0033] Specifically, the two mounting seats 120 are arranged along the length direction of the bottom plate 110, and the two mounting seats 120 are located at the edge parts of the top of the bottom plate 110. The side plate 130 is vertically arranged on the bottom plate 110 along the length direction of the bottom plate 110, and the length of the side plate 130 can be adapted to the distance between the two mounting seats 120. First mounting holes 121 are provided on both of the two mounting seats 120, and both ends of the rotating component 210 are respectively connected to the two first mounting holes 121. A limiting hole 122 is also provided at the top of the mounting seat 120, and the rotating component 210 is limited by a bolt passing through the limiting hole 122 and the first mounting hole 121. Specifically, when corresponding threaded holes are also provided on the rotating component 210, after both ends of the rotating component 210 penetrate through the first mounting holes 121, bolts are respectively used to connect the limiting hole 122 and the threaded holes on the rotating component 210.

[0034] Figure 4 The exploded view of the rotating component of the braking system provided by the embodiment of the present utility model is illustrated. Refer to Figure 4 , in some embodiments of the present utility model, the rotating component 210 includes a fixed rod 211 and a rotating cylinder 213. The fixed rod 211 is limited between the two mounting seats 120; the rotating cylinder 213 is rotatably sleeved outside the fixed rod 211, and a connecting component 230 is arranged outside the rotating cylinder 213, and the connecting component 230 is used for connecting with the brake 300. Retaining rings 212 are also provided at both ends of the retaining ring 212, and the retaining rings 212 can play a role in limiting to prevent the fixed rod 211 from moving.

[0035] In the above structure, the fixed rod 211 is limited between the two mounting seats 120, providing a solid support foundation. This design ensures that the rotating component 210 can maintain a stable operating state when the brake pedal is operated, and is not prone to shaking or deviation. The stability of the fixed rod 211 helps to improve the stability of the entire braking system, ensuring the accuracy and reliability of the braking effect. The rotating cylinder 213 is rotatably sleeved outside the fixed rod 211, realizing the flexible rotation of the brake pedal, which helps to improve the response speed of the braking system, enabling the operator to perform the braking operation faster, thereby improving the operation efficiency and safety of the working machine.

[0036] For the material of the rotating component 210, high-strength and wear-resistant materials can be used, such as stainless steel, aluminum alloy, etc. These materials have good mechanical properties and corrosion resistance, and can maintain stable performance in harsh working environments. In addition, by optimizing the structural design and manufacturing process of the rotating component 210, its durability and service life can be further improved. For example, using precision machining technology and heat treatment processes can improve the surface hardness and wear resistance of the component; using a reasonable lubrication method can reduce the friction and wear between components.

[0037] Refer to Figure 3 , in some embodiments of the present utility model, the side plate 130 is provided with a limiting member 131, and the limiting members 131 are arranged at intervals corresponding to the pedal components 220 one by one. The limiting member 131 is used to prevent the pedal component 220 from rotating excessively.

[0038] Specifically, the limiting member 131 can be a bolt, which is threadedly connected to the side plate 130. Under normal circumstances, there is a gap between the limiting member 131 and the pedal component 220. When the pedal component 220 rotates excessively, it will touch the limiting member 131, and the limiting member 131 will prevent the pedal component 220 from further rotating. By restricting the rotation range of the pedal component 220, it can ensure that the braking operation is carried out within a predetermined safe range, avoiding the accident risk caused by operation errors. The design of the limiting member 131 increases the structural stability of the braking system, enabling the pedal component 220 to maintain a stable movement trajectory during operation and improving the overall performance of the system. In some possible embodiments, a shock-absorbing rubber pad is installed at the contact point between the pedal component 220 and the limiting member 131. The rubber pad can absorb and disperse vibration energy, reducing the impact and noise generated by the braking operation.

[0039] Refer to Figure 3In some embodiments of the utility model, the connecting component 230 includes a first connecting member 231, a second connecting member 232 and a latch 233. The first connecting member 231 is arranged on the rotating cylinder 213; the second connecting member 232 is provided with a groove, and the two side walls of the groove are respectively located on both sides of the first connecting member 231; the latch 233 passes through the groove and the first connecting member 231, and the latch 233 is used to connect the first connecting member 231 and the second connecting member 232.

[0040] Specifically, the second connecting member 232 is a U-shaped groove structure, and one end of the opening is arranged toward the first connecting member 231, the first connecting member 231 is located inside the opening, and the first connecting member 231 is provided with a limiting hole. When the first connecting member 231 and the second connecting member 232 are connected, the latch 233 can be first passed through the first connecting member 231 and the second connecting member 232, and then the limiting rod is inserted into the extended end of the first connecting member 231. In this way, when the rotating component 210 rotates, the first connecting member 231 can be driven to rotate, and then the first connecting member 231 can be pushed to move, and the pedal is transmitted to the brake 300, and the brake 300 brakes.

[0041] Reference Figure 3 In some embodiments of the present invention, the brake pedal component 220 includes a pedal rod 221 and a spring connection block 222. One end of the pedal rod 221 is connected to the rotating cylinder 213, and the other end is provided with a pedal body 223; the spring connection block 222 is provided in the middle of the pedal rod 221, one end of the return spring 240 is connected to the spring connection block 222, and the other end is connected to the spring stop hole 132 on the side plate 130.

[0042] In the above structure, the design of the pedal rod 221 makes the force transmission more direct and stable, which helps to ensure the accurate execution of the braking command. The combination of the spring connecting block 222 and the spring limiting hole ensures that the pedal can quickly and accurately return to the initial position after being released, thereby improving the reliability and response speed of the brake.

[0043] In some possible embodiments, the pedal rod 221 is made of high-strength alloy material, such as aluminum alloy or carbon fiber composite material, to further reduce weight and improve durability. The cross-section of the pedal rod 221 can also be designed to be hollow, and a reinforcing rib structure is provided inside the gap, which not only reduces weight but also improves bending strength. A plurality of spring connecting blocks 222 can be provided on each pedal rod 221, so that a plurality of return springs 240 can be introduced to improve the stability and reliability of return. In other possible embodiments, the upper surface of the pedal body 223 is provided with an anti-skid portion. Specifically, anti-skid patterns or anti-skid grooves are provided on the treading surface of the pedal body 223.

[0044] Reference Figure 3, in some embodiments of the present utility model, the installation assembly 100 further includes a brake limit seat 140. The brake limit seat 140 is provided on the bottom plate 110 and is located on the other side of the two mounting seats 120. The brake limit seat 140 is provided with a second mounting hole 141. The brake 300 passes through the second mounting hole 141 and is connected to the second connecting member 232. Specifically, the brake limit seat 140 is of an L-shaped structure, and such a setting can enhance the stability of the brake limit seat 140. When specifically installing the brake 300, the outer shell of the brake 300 can be detachably connected to the brake limit seat 140 by bolts.

[0045] Referring to Figure 2 , in some embodiments of the present utility model, the brake 300 includes a brake pump 310 and a piston 320. The brake pump 310 is limited in the second mounting hole 141. One end of the piston 320 is slidably disposed inside the brake pump 310, and the other end is threadedly connected to the second connecting member 232. Specifically, the piston 320 passes through the second mounting hole 141, and the brake pump 310 is fixed to the brake limit seat 140 by bolts. When braking, step on the pedal body 223. The pedal body 223 drives the spring connecting block 222 and then drives the rotating cylinder 213 to rotate. The rotating cylinder 213 drives the first connecting member 231 to rotate, and then pushes the second connecting member 232 to move. The second connecting member 232 pushes the piston 320 to move inside the brake pump 310, thereby converting mechanical energy into internal energy. The brake pump 310 controls the operation of each oil circuit, and then brakes.

[0046] The present utility model also provides a working machine, including the braking system according to any one of the above embodiments. It should be noted that in the embodiments of the present utility model, the types of the working machines are not limited. For example, the working machine can be an excavator, a crane, a loader, etc. In other words, as long as the working machine can use the drive axle in the present invention.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model, rather than to limit them; although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present utility model.
