Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of shift fork, especially a shift fork assembly with damping mechanism. BACKGROUND

[0002] The shift fork assembly is an indispensable key component of the clutch, and its stability plays a crucial role in the normal operation of the clutch. When the driver steps on the clutch pedal, the power-assisted pump releases power immediately. This power is transmitted to one end of the shift fork through the push rod, which in turn rotates the power-assisted shift fork. The other end of the shift fork precisely pushes the separating bearing, which exerts a pressing (or pulling) force on the clutch pressure plate, thereby achieving the separation function of the clutch. This process effectively cuts off the power transmission between the vehicle engine and the transmission, ensuring the stability and safety of the vehicle during driving.

[0003] Currently, the existing shift fork (such as announcement number: CN220505632U) discloses a "shift fork assembly and vehicle". The shift fork of this device is Y-shaped, with a long handle at the other end. One end of the long handle is connected to two prongs, and the other end has a mounting hole in the first direction. A bushing is axially inserted into the mounting hole, and the bushing is detachably connected to the long handle. Since the bushing wears more than the long handle, it is designed to be detachably connected. When the bushing is severely worn, it can be replaced in time, while the long handle can be continuously used.

[0004] However, during the implementation of the above technical solution, at least the following technical problems were found: However, due to the complex road conditions, the vehicle often encounters vibrations caused by bumps and other factors during driving. However, since the above shift fork does not have a damping mechanism, the shift fork and the bearings connected to the automobile parts may be misaligned after long-term use, which may affect the practicality and needs to be improved.

DETAILED DESCRIPTION

[0025] The fork assembly with damping mechanism provided by the present application effectively solves the technical problem of insufficient practicability of the existing fork. The bearing seat and the fork connecting arm are arranged on the shaft body, and the damping bearing is arranged inside the main arm of the fork. When the shaft body rotates due to vibration, the shaft body will drive the inner ring of the damping bearing to rotate due to the vibration force. Since the damping bearing itself has certain damping properties, part of the vibration force will be absorbed by the damping bearing when the vibration force is transmitted to the shaft body, thereby achieving the effect of damping the bearing seat and the fork connecting arm on the shaft body, improving practicability, and by arranging the stepped part, the stepped layer and the connecting rod group on the inner ring and connecting the connecting rod group with the bearing seat, the bearing seat can be effectively supported and limited on both sides, thereby improving certain shock resistance.

[0026] EMBODIMENT

[0027] As shown in Figure 1 - Figure 5 The technical solution in the present application effectively solves the technical problem of insufficient practicability of the existing fork. The general idea is as follows:

[0028] In view of the problems in the prior art, the present application provides a fork assembly with a damping mechanism, which comprises a fork leg 11, a main arm 12 of the fork leg 11, a first circular groove 13 symmetrically arranged inside the main arm 12 of the fork, and a damping mechanism arranged inside the two first circular grooves 13.

[0029] The two first circular grooves 13 are arranged inside the two first circular grooves 13.

[0030] The damping mechanism comprises two damping bearings 15, and outer rings 16 and inner rings 17 are arranged outside and inside the two damping bearings 15 respectively, the two outer rings 16 are fixedly installed on the inner walls of the first circular grooves 13, the shaft body 18 is fixedly installed between the two inner rings 17, the bearing seat 21 and the shift fork connecting arm 25 are arranged on the shaft body 18, and the damping bearing 15 is arranged in the shift fork main arm 12, so that when the shaft body 18 rotates due to vibration, the shaft body 18 will drive the inner ring 17 of the damping bearing 15 to rotate due to the vibration force, and since the damping bearing 15 has certain damping properties, part of the vibration force will be absorbed by the damping bearing 15 when the vibration force is transmitted to the shaft body 18, thereby achieving the effect of damping the bearing seat 21 and the shift fork connecting arm 25 on the shaft body 18, and improving the practicability.

[0031] The rubber rings 19 are fixedly installed on the circumferential surface of the shaft body 18, the second circular grooves 14 are arranged on the side walls of the two first circular grooves 13, the diameters of the two second circular grooves 14 are greater than that of the first circular groove 13, the two rubber rings 19 are located at the two ends of the shaft body 18, the two rubber rings 19 are located inside the second circular grooves 14, the two rubber rings 19 are attached to the second circular grooves 14, and the second circular grooves 14 and the rubber rings 19 are arranged on the shaft body 18, so that the rotation of the shaft body 18 will drive the rubber rings 19 to slide and rub inside the second circular grooves 14, thereby inhibiting the vibration force of the shaft body 18 and further improving the damping effect and the practicability.

[0032] The bearing seat 21 is fixedly installed on the circumferential surface of the shaft body 18, the stepped parts 22 are fixedly installed on the side walls of the two outer rings 16, the stepped layers 23 are arranged on the side walls of the two stepped parts 22, the diameters of the two stepped layers 23 are greater than that of the circular hole connected between the bearing seat 21 and the shaft body 18, the connecting rod groups 24 are fixedly installed on the side walls of the two stepped layers 23, the two connecting rod groups 24 are fixedly installed on the bearing seat 21, the shift fork connecting arm 25 is arranged on the circumferential surface of the bearing seat 21, the stepped parts 22, the stepped layers 23 and the connecting rod groups 24 are arranged on the inner ring 17, and the connecting rod groups 24 are connected with the bearing seat 21, so that the bearing seat 21 can be effectively supported and limited from both sides, thereby improving the certain anti-vibration strength.

[0033] Working principle:

[0034] First, when the fork foot 11 and the fork main arm 12 are collectively vibrated, the vibration force is transmitted to the shaft body 18, the inner ring 17 of the damping bearing 15 is rotated by the vibration force, the rubber ring 19 is slid and rubbed in the second circular groove 14, the vibration force of the shaft body 18 is inhibited, and the damping bearing 15 has a certain damping property, so that part of the vibration force is absorbed by the damping bearing 15 when the vibration force is transmitted to the shaft body 18, thereby achieving the damping effect of the bearing seat 21 and the fork connecting arm 25 on the shaft body 18.

[0035] Second, when the shaft body 18 moves the inner ring 17, the inner ring 17 moves the ladder piece 22, the ladder layer 23 and the connecting rod set 24 to rotate around the bearing seat 21 synchronously, thereby always providing the bearing seat 21 with two-sided support and improving stability.

[0036] Finally, it should be noted that: obviously, the above examples are only examples for clearly illustrating the utility model, and are not limited to the implementation. For ordinary skilled in the art, on the basis of the above description, other different forms of changes or changes can be made. Here, it is not necessary and impossible to enumerate all the implementation. The obvious changes or changes derived therefrom are still within the protection scope of the utility model.
