Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction, and therefore cannot be understood as limiting the scope of protection of the present invention.

[0017] The technical solution of the utility model is further described below in conjunction with the accompanying drawings. Figure 1-2The invention shows a tractor brake pedal interlocking device, comprising a left curved plate 1, a right curved plate 2, an R-shaped elastic pin 3, an interlocking pin shaft 4 and a pedal 6. One end of the left curved plate 1 and the right curved plate 2 are both connected to the bottom of the pedal 6. The interlocking pin shaft 4 is vertically penetrated near the bend on the other end of the left curved plate 1 and the right curved plate 2. By arranging the interlocking pin shaft between the left curved plate 1 and the right curved plate 2, when the pedal 6 is stepped on, the left and right wheels are controlled to synchronously realize the braking action. The R-shaped elastic pin 3 is connected to the pin hole arranged on the surface of the interlocking pin shaft 4, and its two ends are arranged on both sides of the right curved plate 2. A spring 5 is arranged on the interlocking pin shaft 4 between the right curved plate 2 and the R-shaped elastic pin 3. By adding a spring at the interlocking pin shaft, the spring can hold and fix the interlocking pin shaft, so as to avoid the interlocking pin shaft vibrating and making noise due to the working vibration of the tractor, thereby achieving the purpose of eliminating the interlocking pin shaft noise.

[0018] As an embodiment of the utility model, pin holes are coaxially provided near the bending part on the other end of the left curved plate 1 and the right curved plate 2, and the interlocking pin shaft 4 passes vertically through them, so that the connection between the interlocking pin shaft 4 and the left curved plate 1 and the right curved plate 2 is more stable, reducing the slight offset effect of the connection.

[0019] As another embodiment of the utility model, a card slot is coaxially provided near the bend on the other end of the left curved plate 1 and the right curved plate 2, and is provided in a card connection with the interlocking pin 4, and the card connection can well provide stability of the connection. Both ends of the interlocking pin 4 extend vertically from the side walls of the left curved plate 1 and the right curved plate 2, and a rubber pad is bonded to the contact surface between the interlocking pin 4 and the card slot. The rubber pad can reduce the effect of the interlocking pin vibrating and emitting noise caused by the working vibration of the tractor, and the spring is combined to support the interlocking pin to play a fixed and damped role, thereby enhancing the effect of eliminating the noise of the interlocking pin.

[0020] In order to enhance the comfort of stepping on the pedal, the surface of the pedal 6 is designed to be slightly raised toward the top in an arc shape, and several rows of protrusions 601 are provided on the surface of the pedal 6 to increase the friction when stepping on it.

[0021] The working principle of this utility model:

[0022] like Figure 1 After stepping on the pedal 6, the interlocking pin 4 connects the left curved plate 1 and the right curved plate 2, and the left curved plate 1 and the right curved plate 2 sink synchronously to control the left and right wheels to achieve braking action synchronously. When the tractor is working, the interlocking pin 4 vibrates, and the spring 5 arranged between the curved plate 2 and the R-shaped elastic pin 3 can support and fix the interlocking pin 4, which plays a role of fixing and absorbing vibration of the interlocking pin 4, thereby eliminating the effect of noise caused by the vibration of the interlocking pin 4.

[0023] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
