[0002] The brake inching mechanism is an essential component of a vehicle's overall system. Its primary function is to provide an easily accessible position for operating the brake and clutch systems, as part of ergonomics. Current designs for brake inching mechanisms primarily utilize a vertically positioned brake valve, which occupies a significant amount of vertical cabin space. This results in low vertical space utilization and fails to meet the design requirements of smaller cabins, such as small forklifts. Due to vehicle height and cabin space limitations, the proper placement and installation of various components to meet pedal requirements and spatial layout becomes an urgent issue. Summary of the Invention

DETAILED DESCRIPTION

[0020] See also Figures 1 to 3The utility model relates to a vehicle brake inching mechanism, comprising a bracket 1, a clutch pedal 2, a brake pedal 3 and a brake valve 4 mounted on the bracket 1, wherein the brake valve 4 is fixedly mounted on the bracket 1 at an angle α between its axis and the horizontal plane; a clutch sleeve 5 and a brake sleeve 6 are coaxially rotatably mounted on the bracket 1;

[0021] The clutch main arm 7 is fixedly mounted on the outer circumference of the clutch sleeve 5; the brake main arm 10 and the brake valve arm 11 are fixedly mounted on the outer circumference of the brake sleeve 6; the brake valve 4 is fixedly mounted on the bracket 1 between the clutch main arm 7 and the brake main arm 10 at an angle. The inclined setting of the brake valve 4 can reduce the space occupied by the entire operating mechanism in the vertical direction. Depending on the corresponding limitations of the actual installation space in the cabin of different vehicles, the corresponding inclination angle α of the brake valve 4 is selected. The optional range of α is 20 to 80 degrees. In the cabin of the small forklift in this embodiment, the angle α is selected to be 50 degrees.

[0022] The clutch pedal 2 and brake pedal 3 are respectively mounted on the outer ends of the clutch main arm 7 and the brake main arm 10; the movable end of the brake valve 4 is hinged to the end of the brake valve arm 11; when the driver steps on the brake pedal 3, the corresponding brake main arm 10 drives the brake sleeve 6 to rotate, thereby driving the brake valve arm 11 to push the brake valve 4 to achieve braking; when the driver steps on the clutch pedal 2, the corresponding clutch main arm 7 drives the clutch sleeve 5 to rotate, thereby triggering the vehicle clutch action;

[0023] A clutch limiting device and a clutch resetting device are provided between the clutch sleeve 5 and the bracket 1 to limit and reset the rotation of the clutch sleeve 5. The clutch limiting device comprises a clutch arm 8 fixedly mounted on the outer ring of the clutch sleeve 5, and a clutch limiting bolt 14 rotated on the bracket 1 and located directly below the clutch arm 8. The clutch limiting bolt 14 is rotated to adjust the height of the clutch arm 8 extending out of the bracket 1. When the clutch sleeve 5 drives the clutch arm 8 to rotate, it is blocked by the clutch limiting bolt 14, thereby limiting the rotation range of the clutch sleeve 5. The clutch resetting device comprises a clutch arm 9 fixedly mounted on the outer ring of the clutch sleeve 5, and a clutch resetting spring 17 connecting the clutch arm 9 to the bottom of the bracket 1. When the driver releases the clutch pedal 2, the clutch resetting spring 17 drives the clutch sleeve 5, the clutch main arm 7 and the clutch pedal 2 to reset through the clutch arm 9.

[0024] Taking into account the brake micro-operation mechanism of the forklift in this embodiment, the clutch and brake action linkage is required, that is, when the clutch pedal 2 is stepped on, the automatic brake needs to be linked. Therefore, a linkage device is provided between the clutch sleeve 5 and the brake sleeve 6, comprising a linkage limit bolt 15 rotated on the clutch support arm 8 and a linkage support arm 16 fixed on the outer ring of the brake sleeve 6; the positions of the linkage limit bolt 15 and the linkage support arm 16 correspond to each other; when the clutch pedal 2 is stepped on, the clutch sleeve 5 rotates to drive the clutch support arm 8 to rotate, and then the linkage limit bolt 15 pushes the linkage support arm 16 to rotate, thereby driving the brake sleeve 6 to rotate, and the brake valve arm 11 then pushes the brake valve 4 to realize the braking action. By adjusting the position of the linkage limit bolt 15, the rotation range of the linkage support arm 16 can be fine-tuned so that the rotation range of the brake valve arm 11 meets the braking action requirement of the brake valve 4.

[0025] A brake limiting device and a brake resetting device are provided between the brake sleeve 6 and the bracket 1 to limit and reset the rotation of the brake sleeve 6. The brake limiting device comprises a brake arm 12 fixedly mounted on the outer ring of the brake sleeve 6, and a brake limiting bolt 18 rotated on the bracket 1 and located directly below the brake arm 12. The brake limiting bolt 18 is rotated to adjust the height of the brake arm 12 extending out of the bracket 1. When the brake sleeve 6 drives the brake arm 12 to rotate, it is blocked by the brake limiting bolt 18, thereby limiting the rotation range of the brake sleeve 6. The brake resetting device comprises a brake arm 13 fixedly mounted on the outer ring of the brake sleeve 6, and a brake resetting spring 19 connecting the brake arm 13 to the bottom of the bracket 1. When the driver releases the brake pedal 3, the brake resetting spring 19 drives the brake sleeve 6, the brake main arm 10 and the brake pedal 3 to reset through the brake arm 13.

[0026] The utility model tilts the brake valve 4 and provides corresponding limit devices and reset devices on the clutch sleeve 5 and the brake sleeve 6, respectively, so that the clutch action and the brake action can be realized in a smaller cabin installation space, thereby reducing the longitudinal dimension space requirement of the brake micro-motion operating mechanism. It can be applied to the design of some brake pedals with limited longitudinal space, meeting the needs of installing the brake micro-motion operating mechanism in vehicles with small cabins.

[0027] In addition: It should be noted that the above specific implementation is only an optimization scheme of this patent. Any changes or improvements made by technicians in this field based on the above concept are within the scope of protection of this patent.
