Description

Technical Field

[0001] This utility model belongs to the field of automobile manufacturing and related technical fields, specifically relating to a rocker arm upper and lower bearing limiting mechanism. Background Technology

[0002] The rocker arm upper and lower bearing limiting mechanism is a device used to limit the displacement or range of motion of the rocker arm in the vertical direction due to the bearing connection. It is usually achieved by multiple components working together.

[0003] However, when the bearing mechanism is not properly lubricated or the lubricating oil becomes less effective, the upper and lower bearings will slide as the rocker arm rotates. When the amount of sliding is large, the bearing will slide off the base, causing the bearing to fail and affecting the product life of the entire disc brake. Utility Model Content

[0004] The purpose of this utility model is to provide a rocker arm upper and lower bearing limiting mechanism to solve the problem mentioned in the background art that when the sliding amount is large, the bearing will slide off the base, causing the bearing to fail.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rocker arm upper and lower bearing limiting mechanism, comprising a rocker arm body and a support base installed on the lower side of the rocker arm body; The upper circular outer wall of the support base is provided with a lower bearing body; The upper bearing body is provided inside the upper circular outer wall of the rocker arm body; The front side of the rocker arm body is provided with multiple lower limit plates, and the rear side of the rocker arm body is provided with an upper limit plate.

[0006] Preferably, one end of each of the plurality of lower limiting pieces is fixedly connected with a first screw.

[0007] Preferably, two second screws are fixedly connected to one side of the upper limit plate, and an adapter groove is provided inside the rear outer wall of the upper limit plate.

[0008] Preferably, a fixing hole is provided inside the upper outer wall of the rocker arm body to allow an external corresponding device to be inserted and connected to the rocker arm body.

[0009] Preferably, a fixing cylinder is provided on one side of the rocker arm body, and a connecting bolt is provided on the upper circular outer wall of the fixing cylinder.

[0010] Preferably, a gear plate is fixedly connected to the lower outer wall of the support base, and a threaded sleeve is fixedly connected to the lower outer wall of the gear plate.

[0011] Preferably, the lower outer wall of the threaded sleeve is provided with a locking screw that engages with the support base.

[0012] Compared with the prior art, this utility model provides a rocker arm upper and lower bearing limiting mechanism, which has the following beneficial effects: By installing upper and lower limit plates, the bearing position is guaranteed to remain fixed throughout the entire lifespan of the disc brake, ensuring effective lubrication and extending the service life of the disc brake. Even if the lubricating oil's effectiveness decreases or the rocker arm's rotation angle increases throughout the disc brake's lifespan, the bearing's range of motion is firmly limited, ensuring it maintains its designated position under all circumstances. No matter the harshness of the operating conditions, the bearing remains stably in place, laying a solid foundation for the reliable operation of the disc brake. This prevents the bearing from slipping out of the lubrication area, effectively reducing wear and failure risks caused by poor lubrication and ensuring the long-term reliability of the braking system.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] This utility model provides, for example Figure 1-5The rocker arm upper and lower bearing limiting mechanism shown includes a rocker arm body 1 and a support base 7 installed on the lower side of the rocker arm body 1; The upper circular outer wall of the support base 7 is provided with a lower bearing body 8; The upper bearing body 9 is provided inside the upper circular outer wall of the rocker arm body 1; Multiple lower limit plates 10 are provided on the front side of the rocker arm body 1, and an upper limit plate 11 is provided on the rear side of the rocker arm body 1. First, the lower bearing body 8 is installed inside the upper circular outer wall of the support base 7, ensuring that the lower bearing body 8 is firmly installed and accurately positioned so that its rolling elements can roll freely. Next, the upper bearing body 9 is installed inside the upper circular outer wall of the rocker arm body 1, ensuring the fit accuracy between the upper bearing body 9 and the rocker arm body 1, so as to smoothly reduce the friction between the rocker arm body 1 and the upper components. Then, the lower limit plates 10 and the upper limit plates 11 are installed. Finally, the rocker arm body 1 is installed on the support base 7, so that the lower bearing body 8 and the rocker arm body 1 are correctly fitted. The upper bearing body 9 and the lower bearing body 8 are lubricated by applying an appropriate amount of lubricating oil or grease. When the disc brake receives a braking signal, the rocker arm body 1, as the actuator of the disc brake, begins to move. The rocker arm body 1 is positioned on the support base 7 with the lower bearing body 8... The main body 8 swings along a shaft, while simultaneously engaging with the upper components via the upper bearing body 9. During the swing, the upper bearing body 9 effectively reduces friction between the rocker arm body 1 and the upper components, making the movement of the rocker arm body 1 smoother. The lower bearing body 8 reduces friction between the rocker arm body 1 and the support base 7, ensuring stable swing of the rocker arm body 1 on the support base 7. During the swing of the rocker arm body 1, the upper limit plate 11 always limits it. If the upper bearing body 9 tends to slide upwards, downwards, or inwards due to the swing of the rocker arm body 1, the upper limit plate 11 will promptly block it, ensuring that the upper bearing body 9 remains in the correct position. Similarly, the lower limit plate 10 limits the lower bearing body 8. When the lower bearing body 8 tends to slide downwards or outwards due to the movement of the rocker arm body 1, the lower limit plate 10 will prevent it from moving, ensuring that the lower bearing body 8 is stably positioned in the specified position on the support base 7.

[0021] like Figure 4 and Figure 5 As shown, one end of each of the multiple lower limit plates 10 is fixedly connected to a first screw 13, and one side of the upper limit plate 11 is fixedly connected to two second screws 14. An adapter groove 15 is provided inside the outer wall of the rear end of the upper limit plate 11.

[0022] Pass the first screw 13 through the mounting hole at one end of the lower limit plate 10, and then screw it into the corresponding threaded hole on the support base 7. During the tightening of the first screw 13, ensure that the lower limit plate 10 is installed in an accurate position and that its limiting surface is at a suitable distance from the outer side of the lower bearing body 8 so as to effectively restrict the lower bearing body 8 from sliding outward. Place the upper limit plate 11 at the predetermined position on the rear side of the rocker arm body 1 so that the mounting hole of the second screw 14 is aligned with the threaded hole on the rocker arm body 1. Then, use a screwdriver or electric wrench to screw the two second screws 14 into the threaded holes on the rocker arm body 1 respectively, and tighten them according to the specified torque to ensure that the upper limit plate 11 is firmly fixed on the rocker arm body 1.

[0023] like Figure 1 As shown, a fixing hole 2 is provided inside the upper outer wall of the rocker arm body 1 to allow external corresponding equipment to be inserted and connected to the rocker arm body 1.

[0024] The external device has a connecting component that is adapted to the fixing hole 2. By inserting the connecting component into the fixing hole 2, a mechanical connection can be established between the two, enabling the rocker arm body 1 to effectively transmit power or motion from the external device when the disc brake is working, thereby driving the rocker arm body 1 to swing according to the design requirements to realize the braking function of the disc brake.

[0025] like Figure 1 As shown, a fixing cylinder 3 is provided on one side of the rocker arm body 1, and a connecting bolt 4 is provided on the upper circular outer wall of the fixing cylinder 3.

[0026] The fixed cylinder 3 and the connecting bolt 4 on the upper circular outer wall of the rocker arm body 1 are mainly used to further fix or connect other related components. The fixed cylinder 3 provides a stable connection structure, and the connecting bolt 4, through the axial force generated by tightening, firmly fixes the components to be connected to the fixed cylinder 3.

[0027] like Figure 1 and Figure 3 As shown, a gear plate 5 is fixedly connected to the lower outer wall of the support base 7, and a threaded sleeve 6 is fixedly connected to the lower outer wall of the gear plate 5. A locking screw 12 that engages with the support base 7 is provided inside the lower outer wall of the threaded sleeve 6.

[0028] The gear structure on the gear plate 5 can cooperate with other gears or racks to realize the transmission of power or the change of the direction of motion, providing a power transmission path for the overall operation of the disc brake. When it is necessary to install the support base 7, first align the threaded sleeve 6 with the corresponding screw hole on the mounting base, and then rotate the locking screw 12 to gradually screw it into the support base 7 until the support base 7 is firmly fixed on the mounting base.

[0029] The implementation principle of this embodiment is as follows: First, the lower bearing body 8 is installed inside the upper circular outer wall of the support base 7, ensuring that the lower bearing body 8 is firmly installed and accurately positioned, allowing its rolling elements to roll freely. Next, the upper bearing body 9 is installed inside the upper circular outer wall of the rocker arm body 1, ensuring the fitting accuracy between the upper bearing body 9 and the rocker arm body 1, so as to smoothly reduce the friction between the rocker arm body 1 and the upper components. Then, the lower limit plate 10 and the upper limit plate 11 are installed. Finally, the rocker arm body 1 is installed on the support base 7, ensuring that the lower bearing body 8 and the rocker arm body 1 are correctly fitted. The upper bearing body 9 and the lower bearing body 8 are lubricated by applying an appropriate amount of lubricating oil or grease. When the disc brake receives a braking signal, the rocker arm body 1, as the actuator of the disc brake, begins to move. The rocker arm body 1 swings on the support base 7 around the fitting point with the lower bearing body 8 as the axis. Simultaneously, the upper bearing body 9 is linked with the upper components. During the swinging process, the upper bearing body 9 effectively reduces the friction between the rocker arm body 1 and the upper components, making the movement of the rocker arm body 1 smoother. The lower bearing body 8 reduces the friction between the rocker arm body 1 and the support base 7, ensuring the stable swinging of the rocker arm body 1 on the support base 7. During the swinging process of the rocker arm body 1, the upper limit plate 11 always limits it. If the upper bearing body 9 tends to slide upward, downward, or inward due to the swinging of the rocker arm body 1, the upper limit plate 11 will block it in time to ensure that the upper bearing body 9 remains in the correct position. Similarly, the lower limit plate 10 limits the lower bearing body 8. When the lower bearing body 8 tends to slide downward or outward due to the movement of the rocker arm body 1, the lower limit plate 10 will prevent it from moving, ensuring that the lower bearing body 8 is stably in the specified position on the support base 7.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
