Description

Technical Field

[0001] The utility model relates to the field of automobiles, in particular to an accelerator pedal assembly. Background Art

[0002] The design of the throttle control system for agricultural three-wheeled vehicles and other similar vehicles (trucks) significantly impacts driver comfort and overall vehicle performance. Conventional accelerator pedal assemblies often suffer from unstable pedaling, high friction, and unreliable return. These factors contribute to driver fatigue during extended driving and insensitive throttle response.

[0003] Specifically, in the prior art, most common accelerator pedal assemblies adopt a simple lever structure, which has the following shortcomings:

[0004] When using a traditional lever-structured accelerator pedal, there is a lot of friction between the pedal and the floor, which causes an unstable pedaling process and is prone to shaking, affecting the driver's operating experience.

[0005] Due to the large friction, the driver needs to exert greater force when stepping on the accelerator. Driving for a long time can easily lead to foot fatigue and reduce driving comfort.

[0006] During the return process, traditional accelerator pedals usually rely on a simple spring structure, which has a slow and inaccurate return speed, and can easily cause the accelerator to stick or not return to its original position, affecting the safety of the vehicle and the driving experience.

[0007] Due to frequent friction and wear, the service life of traditional accelerator pedal assemblies is short, requiring frequent maintenance and replacement, which increases the cost of use. Utility Model Content

[0008] The utility model provides an accelerator pedal assembly to solve the problem that during use of a traditional lever-structured accelerator pedal, there is large friction between the pedal and the floor, which leads to an unstable pedaling process, prone to shaking, and requires frequent maintenance and replacement, which increases the cost of use and affects the driver's operating experience.

[0009] The utility model is realized through the following technical scheme: an accelerator pedal assembly includes a rocker arm, a roller and a tread, the upper part of the rocker arm is provided with a roller shaft, the roller is mounted on the roller shaft and is located at the lower part of the tread; when the tread rotates counterclockwise, the roller drives the rocker arm to rotate; when the rocker arm rotates clockwise, the roller lifts the tread.

[0010] Preferably, it further comprises a base, which is mounted on the bottom plate of the vehicle body, and the rocker arm is mounted on the base via a rocker arm shaft and rotates relative to the base.

[0011] Preferably, it also includes a limiting shaft, which is arranged on the base and limits the counterclockwise rotation angle of the rocker arm.

[0012] Preferably, it further comprises a return spring, one end of which is mounted on the base, and the other end of which is mounted on the rocker arm and provides a rebound force for the rocker arm.

[0013] Preferably, it further comprises a throttle cable support plate, wherein the throttle cable support plate is installed at the bottom of the tread.

[0014] Preferably, it also includes a throttle cable core wire, and the throttle cable core wire is installed on the roller shaft.

[0015] Preferably, the head of the throttle cable core wire is a ring-shaped structure.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] By adopting the roller structure design, the roller can roll at the bottom of the tread when pedaling, thereby effectively improving the stability of accelerator pedaling, reducing friction during pedaling, and making the driver more stable and comfortable when operating.

[0018] Due to the introduction of the roller structure, the transmission between the tread and the rocker arm is carried out through the roller, which reduces direct friction and makes the force required by the driver to step on the accelerator less. At the same time, it improves the response speed of the pedal and improves the driver's pedaling experience.

[0019] The accelerator pedal assembly achieves precise control of the throttle through a roller and cable structure, thereby achieving precise adjustment of different engine speeds, meeting the vehicle's usage requirements under different working conditions, and improving the vehicle's operating performance and work efficiency.

[0020] The return spring provides a reliable rebound force, allowing the pedal to quickly return to its initial position after being released. The setting of the limit shaft ensures that the rocker arm returns to the predetermined initial position, thus ensuring the safety and reliability of the pedal.

[0021] The accelerator pedal assembly has a simple structural design, the base is the main supporting device, and is easy to install. It is suitable for floor installation on agricultural three-wheeled vehicles and has good adaptability.

[0022] In summary, the accelerator pedal assembly improves the stability and comfort of accelerator pedaling through the innovative design of the roller structure, extends the service life of the device, simplifies the structure, facilitates installation and maintenance, and significantly improves the vehicle's operating performance and user experience.

[0027] The present invention will be further described below through specific embodiments in conjunction with the accompanying drawings, but this does not limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.

[0028] The utility model discloses a throttle pedal assembly comprising a rocker arm shaft 1, a limit shaft 2, a rocker arm 3, a roller 4, a roller shaft 5, a tread 6, a return spring 7, a throttle cable support plate 8, a tread shaft 9, and a base. The throttle pedal assembly control device controls the throttle of a three-wheeled agricultural vehicle and achieves variable engine speeds. By utilizing a roller structure, the throttle pedal improves stability and optimizes driver comfort.

[0029] In the above embodiment, the accelerator pedal assembly is mounted on the vehicle body floor. The base 10 is the main supporting device and is fixed to the vehicle body floor. The rocker arm shaft 1 and the tread shaft 9 are mounted on the base 10. The rocker arm 3 and the tread 6 can both rotate around the corresponding shafts. Specifically, the roller shaft 5 is mounted on the top of the rocker arm 3, and the roller 4 is mounted on the roller shaft 5. The tread 6 is naturally pressed against the roller 4. The throttle cable is mounted on the throttle cable support plate 8, and the throttle cable support plate 8 is fixed to the bottom of the tread 6. One end of the return spring 7 is mounted on the base 10, and the other end of the return spring 7 is mounted on the rocker arm 3 to provide a rebound force. The limit shaft 2 is set on the base 10 and limits the rotation angle (initial position) of the rocker arm 3. At the same time, anti-wear bushings are provided at each shaft to increase the service life of the assembly.

[0030] When the accelerator pedal assembly is in operation, the head of the accelerator cable core wire is a ring-shaped structure, mounted on roller shaft 5 together with roller 4. The throttle cable sleeve is fixed to throttle cable support plate 8 and remains stationary relative to tread 6. When tread 6 is stepped on, it rotates counterclockwise about tread shaft 9, pressing down on roller 4. This pressure is transmitted to rocker arm 3, causing it to rotate counterclockwise about rocker arm shaft 1. The different rotation paths of tread 6 and rocker arm 3 cause roller 4 to roll from the bottom of tread 6 to its front end, pulling the throttle cable forward to achieve the throttle function.

[0031] When the pedal is unloaded, the return spring 7 pulls the rocker arm 3, causing it to rotate clockwise around the rocker arm shaft 1. During the rotation, the position of the roller 4 rises relative to the base 10, lifting the tread 6 and rolling on the bottom of the tread 6 toward its rear end, and is recovered together with the throttle cable core wire until the rocker arm 3 hits the limit shaft and all components return to their original positions, realizing the return function.

[0032] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
