Abstract
Description
Technical Field
[0001] The utility model relates to a brake override control structure. Background Art
[0002] Wheeled harvesting machines mostly use HST as the power source, and the mechanism for controlling the walking generally uses a handle control. Pushing the operation handle enables the HST variable to achieve machine walking. If the machine needs to stop, the handle needs to return to the middle position. Stepping on the brake alone cannot cancel the HST power, which brings a lot of insecurity. Content of the Utility Model
[0003] The purpose of the utility model is to solve the above-mentioned deficiencies of the prior art and provide a brake override control structure.
[0004] A brake override control structure includes a walking middle-position guide groove plate, a walking control plate, and a brake control rod. The middle-position guide groove plate and the walking control plate are rotationally connected through a rotating shaft. The middle-position guide groove plate is provided with a straight long slot hole, and the walking control plate is provided with a reset hole corresponding to the long slot hole. The reset hole is narrow at the top and wide at the bottom, and the bottom of the reset hole is wider than the bottom of the reset hole. The top of the reset hole communicates with the bottom of the reset hole in size. The long slot hole and the reset hole are located above the rotating shaft. The same walking reset pin shaft is inserted through the long slot hole and the reset hole. The walking reset pin shaft is connected to the brake control rod, and the brake control rod is connected to the brake pedal. The brake control rod drives the walking reset pin shaft to move along the long slot hole with the movement of the brake pedal.
[0005] Preferably, when the walking control plate is in the middle position, it is at the middle position between the long slot hole and the reset hole on the walking middle-position guide groove plate.
[0006] Preferably, the number of the walking middle-position guide groove plates is two. The two ends of the bottom of the two walking middle-position guide groove plates are respectively fixedly connected by bolts. The walking control plate is located between the two walking middle-position guide groove plates. The rotating shaft passes through the walking middle-position guide groove plate and the walking control plate. The brake control rod is of a U-shaped structure, and its opening faces the bottom of the walking middle-position guide groove plate. The brake control rod is clamped outside the two middle-position guide groove plates. The walking reset pin shaft passes through the brake control rod, the long slot hole of the middle-position guide groove plate, and the reset hole of the walking control plate.
[0007] Preferably, a plug pin is inserted radially through the end of the pin shaft.
[0008] Beneficial effects: Compared with the prior art, the utility model defines the movement track of the walking return pin through the long slot hole on the walking middle guide groove plate, thereby interfering with the inner wall of the return hole of the walking control plate, and driving the walking control plate to rotate with the movement of the walking return pin. The walking return pin is connected to the brake pedal, so as to realize the linkage between the brake pedal and the walking control plate, and make the walking control plate rotate to the middle position with the movement of the pedal, ensuring driving safety.

[0017] In order to deepen the understanding of the utility model, the following will further elaborate on the utility model in combination with embodiments and drawings. The embodiments are only used to explain the utility model and do not constitute a limitation on the protection scope of the utility model.
[0018] As Figure 1-7 shown, brake control lever 1, walking middle guide groove plate 2, walking control plate 3, walking return pin 4, plug pin 5, rotating shaft 6, bolt 7, long slot hole 8, return hole 9;
[0019] A brake override control structure, including a walking middle guide groove plate 2, a walking control plate 3, and a brake control rod 1. The middle guide groove plate is rotatably connected to the walking control plate 3 through a rotating shaft 6. A straight long slot hole 8 is provided on the middle guide groove plate, and a reset hole 9 corresponding to the long slot hole 8 is provided on the walking control plate 3. The reset hole 9 is narrow at the top and wide at the bottom, and the bottom of the reset hole 9 is wider than the bottom of the reset hole 9. The top of the reset hole 9 communicates with the bottom of the reset hole 9. The long slot hole 8 and the reset hole 9 are located above the rotating shaft 6. The same walking reset pin shaft 4 is inserted through the long slot hole 8 and the reset hole 9. The walking reset pin shaft 4 is connected to the brake control rod 1, and the brake control rod 1 is connected to the brake pedal. The brake control rod 1 drives the walking reset pin shaft 4 to move along the long slot hole 8 with the movement of the brake pedal.
[0020] In this embodiment, when the walking control plate 3 is in the middle position, it is at the middle position between the long slot hole 8 and the reset hole 9 on the walking middle guide groove plate 2.
[0021] In this embodiment, the number of the walking middle guide groove plates 2 is two. The two ends of the bottom of the two walking middle guide groove plates 2 are respectively fixedly connected by bolts 7. The walking control plate 3 is located between the two walking middle guide groove plates 2. The rotating shaft 6 passes through the walking middle guide groove plate 2 and the walking control plate 3. The brake control rod 1 is of a U-shaped structure, and its opening faces the bottom of the walking middle guide groove plate 2. The brake control rod 1 is clamped outside the two middle guide groove plates. The walking reset pin shaft 4 passes through the brake control rod 1, the long slot hole 8 of the middle guide groove plate, and the reset hole 9 of the walking control plate 3.
[0022] In this embodiment, a pin 5 is inserted radially through the end of the pin shaft.
[0023] Instructions for use: Under normal driving conditions, the walking reset pin shaft 4 is located at the bottom of the long slot hole 8. When braking, the brake pedal drives the brake control rod 1, and the brake control rod 1 then drives the walking reset pin shaft 4 to move to the other end along the long slot hole 8. At the same time, the walking reset pin shaft 4 moves from the wider bottom to the narrower top in the reset hole 9. During the movement, since the middle guide groove plate is fixed and the walking control plate 3 is rotatably connected, when interference occurs between the walking reset pin shaft 4 and the inner wall of the reset hole 9, relative movement occurs between the walking control plate 3 and the walking reset pin shaft 4, and the walking control plate 3 will gradually rotate to the middle position with the movement of the walking reset pin shaft 4.
[0024] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
