[0023] In the description of the present invention, it should be understood that the terms "front", "rear", "left", "right", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the protection content of the present invention.

[0024] like Figure 1 , Figure 2 and Figure 3 As shown, a mechanical throttle pedal bracket assembly includes an throttle pedal 1, an throttle pedal bracket 3, an throttle pedal mounting bracket 4, an throttle pedal bracket assembly 5 and an throttle wire drawing assembly 6;

[0025] The accelerator pedal 1 is used for the driver to step on it, so as to accelerate the acceleration system; the accelerator pedal 1 is rotatably mounted on an accelerator pedal bracket 3, and the accelerator pedal bracket 3 is fixed on an accelerator pedal mounting bracket 4 on the interior of the cab;

[0026] The throttle pedal bracket assembly 5 includes a connected rocker arm assembly 504 and a drawing box 505, and the drawing box 505 is installed on the floor sheet metal on the interior of the cab. One end of the rocker arm assembly 504 is provided with a pedal rocker arm 510 hinged to the throttle pedal 1, and the other end is provided with a drawing rocker arm 512. The drawing rocker arm 512 is provided with a guide waist hole 513, and the drawing box 505 is provided with a guide groove 514. A pin shaft 511 is installed in the guide waist hole 513 and the guide groove 514, and the pin shaft 511 is connected to the throttle drawing assembly 6. The utility model adopts a combination of a rocker arm assembly 504 and a wire drawing box 505, so that the lowest point of the drawing end pin shaft 511 at the guide groove 514 of the wire drawing box 505 is the initial limit, and the highest point is the movement limit. Through the adjustment of the guide waist hole 513 of the drawing rocker arm 512 and the guidance of the guide groove 514 of the wire drawing box 505, the pin shaft 511 is guided and adjusted from rotary motion to linear motion. This structure is reliable and ingenious, and solves the problems of the traditional pedal structure being too simple and lacking in guiding and limit limiting functions.

[0027] In some embodiments, Figure 3 As shown, the rocker arm assembly 504 and the wire drawing box 505 are connected by a push rod rocker arm shaft 506, a hexagonal flange nut 501, a door-type bracket 1 502, and a door-type bracket 2 507. A reinforcing plate 503 is installed on the door-type bracket 1 502, and the overall structure is more stable.

[0028] In some embodiments, Figure 2 , Figure 3 As shown, the wire drawing rocker arm 512 is welded on the rocker arm assembly 504, and the wire drawing rocker arm 512 is provided with a guide waist hole 513 arranged in the front-to-back direction; the wire drawing box 505 is provided with a guide groove 514 arranged in the up-down direction. The movement of the wire drawing end pin 511 should be a rotary movement, but relying on the front-to-back movement adjustment of the pin 511 in the guide waist hole 513 of the wire drawing rocker arm 512 and the up-down guidance in the guide groove 514 of the wire drawing box 505, the linear movement of the pin 511 is realized, and then the axial movement of the throttle wire drawing assembly 6 is realized.

[0029] In some embodiments, Figure 3 As shown, a spring pull ring bracket is welded to the end of the wire drawing rocker arm 512 of the rocker arm assembly 504, and a spring pull ring bracket is also welded to the wire drawing box 505, and a return spring 508 is installed between them. When the accelerator pedal 1 is stepped on, the rocker arm assembly 504 performs a rotational motion, and the wire drawing rocker arm 512 will drag the return spring 508 to stretch and deform. If the accelerator pedal 1 is released, the return spring 508 pulls the wire drawing rocker arm 512 to perform a reverse rotational motion, and the pedal rocker arm 510 at the other end drives the accelerator pedal 1 to reset. The return spring 508 provided on the rocker arm assembly 504 can realize automatic return and realize the acceleration and release functions.

[0030] In some embodiments, Figure 2 , Figure 3 As shown, the rocker arm assembly 504 is also provided with a switch pressure plate 516 to achieve the triggering and closing of the throttle switch element.

[0031] In some embodiments, Figure 3 As shown, an adjusting pad 509 is welded on the rocker arm assembly 504, and a hexagon socket bolt 515 is assembled on the wire drawing box 505 as a top screw structure. The adjusting pad 509 on the rocker arm assembly 504 will touch the top screw structure on the wire drawing box 505 during the rotational movement. This design can play the role of end limit. Since the hexagon socket bolt 515 can use double nuts to adjust the extended length, the end limit can be adjusted to increase or decrease the pedaling stroke of the accelerator pedal assembly.

[0032] In some embodiments, the utility model connects the accelerator pedal 1 and the accelerator pedal bracket 3 through the pedal pin 2 and the open retaining ring. When the driver or passenger steps on the accelerator pedal 1, the accelerator pedal 1 can rotate around the pedal pin 2, and the accelerator pedal bracket 3 is fixed on the accelerator pedal mounting bracket 4 on the interior of the cab.

[0033] In some embodiments, the wire drawing box 505 is welded by two wire drawing box vertical plates and a wire drawing box top plate, which realizes the initial limit, movement limit, and linear motion guidance of the wire drawing end during the movement of the accelerator pedal.

[0034] During the rotational movement of the accelerator pedal 1, the pedal rocker arm 510 on one side of the rocker arm assembly 504 will rotate around the push rod rocker arm rotating shaft 506, and the wire drawing rocker arm 512 on the other side of the rocker arm assembly 504 will drive the pin 511 to move linearly in the guide groove 514 (arranged in the up and down direction) on the wire drawing box 505, and the pin 511 will drag the throttle wire drawing assembly 6 to move linearly in the up and down directions to achieve acceleration of the acceleration system. Under the joint action of the guide groove 514 on the wire drawing box 505 and the guide waist hole 513 on the wire drawing rocker arm 512, the rotational movement of the pin 511 can be adjusted to linear movement, and the pin 511 will drag the throttle wire drawing assembly 6 to move linearly up and down.

[0035] The utility model uses the rocker assembly as the spiral pair of the spiral transmission. This rocker assembly integrates the pedal rocker, the wire drawing rocker, the return spring, etc., and uses the spiral transmission to convert the rotary motion of the deep pedal into the linear motion of the wire drawing end by means of the spiral pair, so as to realize the acceleration and release of the acceleration system. It integrates the functions of automatic reset, initial limit, end limit, motion guide, switch trigger, etc., and has a reliable structure and complete functions. While meeting the normal use of the acceleration system, it also solves the defects of the traditional accelerator pedal without motion guide, limit, easy fatigue fracture of wire drawing, etc., and optimizes the acceleration system of the National I and National II export heavy-duty fuel trucks.

[0036] In addition, those skilled in the art will understand that, although some embodiments described herein include certain features included in other embodiments but not other features, the combination of features of different embodiments also means being within the scope of protection of the present utility model and forming different embodiments. For example, in the above embodiments, those skilled in the art can use them in combination according to the known technical solutions and the technical problems to be solved by the present application.
