Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0018] Example Depend on Figures 1 to 3 As shown, this utility model provides a hanging brake pedal, including a wall-mounted bracket 1, a brake push rod 2, a brake pedal 3, and a reset device. The wall-mounted bracket 1 has a mounting portion 11 protruding outwards from its center for mounting a master cylinder 5, and a rotating shaft 12 at its upper end. The lower end of the brake push rod 2 passes through the mounting portion 11 and connects to the master cylinder 5, while its upper end is hinged to the rotating shaft 12. A hinge portion 16 is fixedly provided on the rotating shaft 12, and a U-shaped hinge portion is provided at the upper end of the rotating shaft 12. The upper end of the rotating shaft 12 is hinged to the master cylinder 5 through the U-shaped hinge portion and the hinge portion 16. The brake pedal 3 is inclined to the wall-mounted bracket 1, and its upper end is fixedly connected to the rotating shaft 12. When the brake pedal 12 is subjected to a pressing force, it can drive the brake push rod 2 downwards through the rotating shaft 12, thereby pushing the master cylinder 5 to achieve braking. The reset device is connected to the brake pedal and the wall-mounted bracket 1. After the brake pedal 12 is released, the reset device can drive the brake pedal 3 to reset, and the brake pedal 3 drives the brake push rod 2 to reset via the rotating shaft 12.
[0019] In this embodiment, the wall-mounted bracket 1 is connected to the lower end of the front wall of the driver's cab, and the master cylinder 5 is installed inside the mounting part 11. The brake pedal 3 drives the brake push rod 2 downward through the rotating shaft 12 to push the master cylinder 5 to achieve braking. This allows the entire brake pedal to be installed in a suspended manner in the driver's cab, saving layout space in the driver's cab. Moreover, since the master cylinder 5 is installed at the front of the vehicle, the front of the vehicle can be directly opened to inspect and maintain the master cylinder, making maintenance convenient.
[0020] The upper end of the wall-mounted bracket 1 is provided with a first connecting portion 13 and a second connecting portion 14, both of which have through holes. The two ends of the rotating shaft 12 pass through the through holes and are rotatably connected between the first connecting portion 13 and the second connecting portion 14. The first connecting portion 13 is formed by extending upward from the left side wall of the mounting portion 11, so that the brake push rod 2 can be accommodated within the space enclosed by the left side wall and the top wall of the wall-mounted bracket 1 and the mounting portion 11, making the overall structure more compact. Limiting caps 15 are connected to both ends of the rotating shaft 12 to prevent axial displacement of the rotating shaft 12.
[0021] Reference Figure 2 As shown, the reset device includes a spring 4, a hanging hole 41 at the front end of the second connecting part 14, and a hanging rod 42 on the brake pedal 3. The spring 4 has hooks at both ends, which are respectively suspended from the hanging hole 41 and the hanging rod 42. The hanging rod 42 has a limiting groove 43, and the hooks connecting the spring 4 and the hanging rod 42 are placed within the limiting groove 43, thereby preventing the spring 4 from moving left or right. The reset device uses a spring, which is easy to replace and install, facilitating pedal maintenance.
[0022] Reference Figure 1 As shown, it also includes a limiting bolt 6. A third connecting part 17 is fixedly provided on the rotating shaft 12, and the limiting bolt 6 is connected to the third connecting part 17. One end of the limiting bolt 6 with a nut abuts against the wall-mounted bracket 1, and the other end is provided with a nut 61. By rotating the nut 61, the distance between the third connecting part 17 and the wall-mounted bracket 1 can be adjusted, and the tilt angle between the brake pedal 3 and the wall-mounted bracket 1 can be further adjusted by the rotating shaft 12, thereby adjusting the initial foot height of the brake pedal 3 so that the brake pedal is higher than the accelerator pedal, making it easier for the driver to switch pedals. Each time the brake pedal is released, the spring 4 can drive the brake pedal 3 to return to the position where the limiting bolt 6 abuts against the wall-mounted bracket 1, thereby resetting the brake pedal.
[0023] Preferably, the lever ratio of the suspended brake pedal of this application is 8:1. The lever ratio of 8:1 can reduce the pedal force, so that the braking force that originally required 2000N to complete the full stroke can be completed with only 250N.
[0024] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
