Description

Technical Field

[0001] This utility model relates to the field of clutches, and in particular to a clutch handle with quick cable adjustment. Background Technology

[0002] When a motorcycle is in motion, the clutch needs to be operated and controlled frequently. The device for operating and controlling the clutch is the clutch lever located in front of the motorcycle handlebars and the clutch cable connected to the clutch lever. By squeezing the clutch lever and then pulling the clutch cable, the clutch action is controlled.

[0003] Chinese utility model patent CN211107842U discloses a clutch handle, including a clutch end, a clutch rod and a cable connector on the clutch end, and a locking nut on the cable connector. The key feature is that the cable connector rotatably engages with the clutch end and is locked by the locking nut. The clutch end has two cable mounting points for adjusting the cable rotation radius. The advantages are that the cable connector can be rotated to adjust the cable orientation and select appropriate cable mounting points, making cable operation easier and reducing driver fatigue.

[0004] In the above scheme, the clutch lever end 1 is equipped with a clutch rod 2 and a cable connector 3. The cable connector 3 is equipped with a locking nut 4. The cable connector 3 is rotatably engaged with the clutch lever end 1 and locked by the locking nut 4. Tightening the locking nut 4 presses it tightly against the clutch lever end 1, at which point the cable connector 3 cannot rotate. Loosening the locking nut 4 disengages it from the clutch lever end 1, allowing the cable connector 3 to rotate. After rotating to a suitable operating angle, the locking nut 4 is tightened again. The clutch lever end 1 is equipped with two cable mounting points 5 for adjusting the cable rotation radius. The appropriate cable mounting point 5 can be selected according to usage requirements to change the cable rotation radius, making cable operation easier and reducing driver fatigue. However, this method has the following problems in actual use:

[0005] 1. The existing clutch handle requires loosening the locking nut, adjusting the angle of the cable connector, and then re-locking it in order to change the direction of the cable or the radius of rotation. This process requires repeated operation of the nut and cable connector, which is inefficient and the cable adjustment stroke is too short.

[0006] 2. At the same time, the clutch lever 2 and the clutch end 1 are hinged by a pin, resulting in an elastic rotational engagement during the rotation of the clutch lever. However, this method will cause the clutch lever to wear after rotating for a long time, resulting in gap oscillation during the clutch lever's engagement and disengagement. Summary of the Invention

[0007] The technical problem to be solved by this utility model is to provide a clutch handle with quick cable adjustment, which addresses the shortcomings of the prior art.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a clutch handle for quick adjustment by pull cable, comprising a handle connecting seat, a handle hinged to the handle connecting seat, a pull cable connector and an adjusting nut. The handle connecting seat has a rotating mounting part at one end away from the handle. The adjusting nut is rotatably connected to the rotating mounting part. The pull cable connector is threaded to the inner wall of the adjusting nut and extends and retracts back and forth within the adjusting nut as it rotates.

[0009] Using the above technical solution, the adjusting nut forms a rotating pair with the handle connecting seat through the rotating mounting part, allowing the adjusting nut to rotate freely around the axis of the rotating mounting part. The pull cable connector is embedded in the inner wall of the adjusting nut through a threaded fit. When the adjusting nut rotates, its inner wall thread drives the pull cable connector to produce a linear displacement along the axial direction (i.e., parallel to the axis of the rotating mounting part), thereby directly changing the extension and retraction position of the pull cable connector and realizing linear adjustment of the tension or relaxation of the pull cable. Compared with the existing technology, which requires loosening the locking nut, adjusting the angle of the pull cable connector, and re-locking, this solution directly drives the linear displacement of the pull cable connector by rotating the adjusting nut, eliminating the step of repeatedly loosening and tightening the nut, simplifying the operation process. The pull cable adjustment steps are simplified from "loosening the nut - adjusting the angle - tightening the nut" to a single rotation action, significantly improving the operation efficiency. The linear adjustment mechanism ensures that the tension of the pull cable is directly proportional to the rotation angle of the adjusting nut, and the adjustment accuracy is controllable.

[0010] The aforementioned clutch handle for quick cable adjustment can be further configured such that: the handle is provided with a cable connection part, and the cable connector has a through groove for the cable to pass through and connect with the cable connection part.

[0011] By adopting the above technical solution, the through-slot design of the pull cable connection part on the handle and the pull cable connector ensures that the pull cable metal wire is fixed to the pull cable connection part after passing through the through slot, forming a continuous path for pull cable transmission.

[0012] The aforementioned quick-release adjustable clutch handle can be further configured such that: the handle connecting seat extends toward one end of the adjusting nut to form the rotating mounting part, the outer circumferential surface of the rotating mounting part is provided with an annular groove, the adjusting nut is provided with at least one rotating shaft corresponding to the outer circumferential surface of the annular groove, and the outer circumferential surface of the rotating shaft abuts against the annular groove.

[0013] Using the above technical solution, the handle connector extends towards its adjusting nut end to form an integrated rotating mounting part. An annular groove is formed on the outer circumferential surface of the rotating mounting part, forming a rotating pair with the rotating shaft on the outer circumferential surface of the adjusting nut. The axis of the rotating shaft is perpendicular to the rotation axis of the adjusting nut, and its outer circumferential surface contacts and engages with the inner wall surface of the annular groove. This allows the rotating shaft to roll or slide circumferentially along the annular groove when the adjusting nut rotates around the axis of the rotating mounting part, thereby achieving circumferential limiting and radial support for the rotational movement of the adjusting nut. The contact surface between the rotating shaft and the annular groove provides stable radial support force, preventing the adjusting nut from swaying radially during rotation and ensuring the straightness of the axial displacement of the pull cable connector. The integrated rotating mounting part and annular groove design enhance structural strength, avoid the risk of loosening of separate connectors, and constrain the rotation of the adjusting nut to a single degree of freedom, avoiding thread jamming or wear caused by radial offset during adjustment.

[0014] The aforementioned quick-release adjustable clutch handle can be further configured as follows: the adjusting nut has a rotating groove connected to the rotating mounting part, the adjusting nut has at least one rotating shaft mounting hole corresponding to the annular groove, the rotating shaft is installed in the rotating shaft mounting hole, and one end of the rotating groove has a connecting hole that abuts against the surface of the annular groove.

[0015] Using the above technical solution, the rotating groove inside the adjusting nut forms an axial sleeve with the rotating mounting part, ensuring that the adjusting nut can rotate freely around the axis of the rotating mounting part while restricting its radial displacement. The rotating shaft mounting hole is located at the position of the corresponding annular groove of the adjusting nut. The rotating shaft is fixed to the adjusting nut through the mounting hole, and its axis is perpendicular to the rotation axis of the adjusting nut. One end of the rotating shaft abuts against the surface of the annular groove through the connecting hole, forming a sliding or rolling contact, which constrains the rotational movement of the adjusting nut within the trajectory of the annular groove, preventing radial offset. The contact surface between the rotating shaft and the annular groove provides radial support force to counteract the lateral load when the adjusting nut rotates, ensuring the linear displacement accuracy of the pull wire joint during thread transmission. The design of the connecting hole allows the rotating shaft to directly contact the surface of the annular groove, avoiding the swinging of the adjusting nut due to installation gaps.

[0016] The aforementioned quick-release clutch handle can be further configured as follows: there are two rotating shafts, which are respectively disposed at both ends of the adjusting nut; the handle connecting seat has a pull cable channel for the pull cable to enter the pull cable connecting part from the through groove; the pull cable connector passes through the adjusting nut and is inserted into the pull cable channel, and moves back and forth in the pull cable channel as the adjusting nut rotates; the through groove, the rotating mounting part and the pull cable channel are all provided with notches.

[0017] Using the above technical solution, two rotating shafts are symmetrically arranged at both ends of the adjusting nut, forming two-point contact with the annular groove of the handle connector. By limiting the circumference of the annular groove with dual shafts, the adjusting nut is forced to rotate purely around the axis of the rotating mounting part (without radial offset), ensuring the linear displacement trajectory of the pull cable connector along the pull cable channel. The fit between the rotating shaft mounting hole and the connecting hole allows the rotating shaft to simultaneously undertake the functions of axial positioning (through the rotating groove and the rotating mounting part) and radial support (through the rotating shaft and the surface of the annular groove), forming a stable rotating pair. After the pull cable connector passes through the adjusting nut, it is inserted into the pull cable channel. Its axial movement is guided by the inner wall of the channel, avoiding bending or wear of the pull cable due to non-linear movement. The through groove, adjusting nut, rotating mounting part and pull cable channel are all provided with notches to form a continuous open lateral entrance, allowing the pull cable metal wire and sleeve to directly pass through the through groove from the side and extend to the pull cable connection part, simplifying the assembly process. The pull cable can be installed or replaced without disassembling the adjusting nut. At the same time, the misalignment setting after the adjustment nut is rotated prevents the pull cable from coming out.

[0018] The aforementioned clutch handle for quick cable adjustment can be further configured such that: one end of the cable connector is provided with a threaded portion that is threadedly connected to the adjusting nut, and the other end is provided with a cable limiting portion, wherein a connector limiting step is formed between the cable limiting portion and the threaded portion.

[0019] Using the above technical solution, the threaded part of the pull cable connector engages with the inner thread of the adjusting nut, converting the rotational motion of the adjusting nut into the axial linear displacement of the pull cable connector, thereby achieving linear adjustment of the cable tension. The outer diameter of the pull cable limiting part is larger than that of the threaded part, forming a limiting step for the connector. When the pull cable connector moves to its limit position, the limiting step abuts against the corresponding structure of the adjusting nut or the handle connecting seat, limiting the stroke range of the pull cable connector and preventing it from dislodging or excessively displacing. During the axial movement of the pull cable connector, the limiting step contacts the end face of the adjusting nut or the inner wall of the handle connecting seat, providing a rigid mechanical stop to ensure that the pull cable connector moves stably within a preset stroke (such as 0-15mm), avoiding cable breakage or mechanical damage due to overtravel.

[0020] The aforementioned quick-release adjustable clutch handle can be further configured such that: a contact feedback component is provided between the handle connecting seat and the adjusting nut; the contact feedback component includes a spring mounting hole on the handle connecting seat, a spring and a ball disposed in the spring mounting hole, and several feedback holes on the surface of the adjusting nut; the spring pushes the ball to move toward one end of the adjusting nut, and as the adjusting nut rotates, the ball enters or leaves the feedback hole.

[0021] Using the above technical solution, the spring in the spring mounting hole pushes the ball towards the surface of the adjusting nut through preload. When the adjusting nut rotates, the ball is periodically compressed by the surface pressure of the adjusting nut. The feedback holes evenly distributed on the surface of the adjusting nut match the diameter of the ball. When the adjusting nut rotates until the ball is aligned with the feedback hole, the ball is embedded in the hole under the action of the spring force, producing a "click" tactile and audible feedback. When the adjusting nut continues to rotate, the ball is squeezed back by the edge of the feedback hole, disengages from the current hole position and slides into the adjacent arc-shaped connecting groove, until it enters the next feedback hole. Thus, the user can perceive the adjustment progress without visual confirmation, reducing the risk of misoperation. The mechanical interlock between the ball and the feedback hole improves the resistance to vibration and loosening.

[0022] The aforementioned clutch handle for quick cable adjustment can be further configured as follows: the feedback hole is disposed around the cable connector on the outer surface of the adjusting nut, and an arc-shaped connecting groove is provided between adjacent feedback holes; one end of the handle connecting seat corresponding to the spring mounting hole is provided with a feedback adjusting screw threadedly connected to the handle connecting seat; one end of the spring abuts against the feedback adjusting screw, and the other end abuts against the ball bearing.

[0023] Using the above technical solution, the feedback hole is set around the pull wire connector on the outer surface of the adjusting nut. Adjacent feedback holes are transitioned by an arc-shaped connecting groove, allowing the ball to slide along the arc-shaped groove when the adjusting nut rotates, reducing the frictional resistance between the ball and the surface of the adjusting nut, and ensuring that the ball slides smoothly into the next feedback hole. The radius of curvature of the arc-shaped connecting groove matches the diameter of the ball, preventing the ball from getting stuck or jumping when moving between holes, and ensuring the continuity of tactile feedback. The feedback adjusting screw is threaded to the spring mounting hole of the handle connector. Rotating the adjusting screw can change the compression of the spring at its end, thereby adjusting the preload of the spring on the ball. The preload adjustment range covers light touch (low resistance adjustment) to strong locking (high anti-loosening force).

[0024] The aforementioned quick-release adjustable clutch handle can be further configured such that: a contact switch is provided at one end of the handle connecting seat corresponding to the handle, and a protrusion is provided on the handle corresponding to the contact switch.

[0025] Using the above technical solution, the contact switch is fixed to one end of the handle corresponding to the handle connector, with its trigger end facing the gripping movement path of the handle. When the handle is gripped, the protrusion rotates away from the trigger end of the contact switch with the hinge, generating an electrical signal. The contact switch is linked with the motorcycle safety system ECU to reduce the risk of accidental start.

[0026] The aforementioned quick-release adjustable clutch handle can be further configured as follows: one end of the handle is hinged to the handle connecting seat; the handle connecting seat has a hinge hole; the handle has a bearing mounting hole that mates with the hinge hole; a hinge shaft passes through the hinge hole and the bearing mounting hole; at least two sets of ball bearings are provided in the bearing mounting hole; the two sets of ball bearings are fixed in the bearing mounting hole with an interference fit; a bushing is provided between the two sets of ball bearings; and the hinge shaft passes through the hinge hole, the bearing mounting hole, the ball bearings, and the bushing.

[0027] Using the above technical solution, two sets of ball bearings are interference-fitted and fixed in the bearing mounting holes of the handle. Through the rolling friction between the inner and outer rings of the bearings and the balls, the sliding friction between the handle and the hinge shaft is converted into low-resistance rolling friction, ensuring smoother rotation of the handle around the hinge shaft. The bushing is set between the two sets of ball bearings to precisely limit the bearing spacing and distribute the axial load, avoiding uneven wear caused by uneven bearing spacing, and preventing axial movement of the hinge shaft. Through the interference fit between the inner ring of the ball bearing and the hinge shaft, radial clearance is eliminated, achieving zero-clearance hinge, extending service life, preventing handle wobbling, and making installation and maintenance more convenient.

[0028] The present invention will now be further described with reference to the accompanying drawings. Attached Figure Description

[0035] like Figures 1-6As shown, a quick-release clutch handle with cable adjustment includes a handle connector 1, a handle 2 hinged to the handle connector 1, a cable connector 3, and an adjusting nut 4. The handle connector 1 has a rotating mounting portion 11 at the end furthest from the handle 2. The adjusting nut 4 is rotatably connected to the rotating mounting portion 11. One end of the cable connector 3 has a threaded portion 31 that is threaded to the inner wall of the adjusting nut 4, and the other end has a cable limiting portion 32. The outer diameter of the cable limiting portion 32 is larger than that of the threaded portion 31, forming a connector limiting step 33 between the cable limiting portion 32 and the threaded portion 31. The handle 2 has a cable connecting portion 21, and the cable connector 3 has an opening for the cable to pass through and engage with the pull cable. The cable connection part 21 is connected to the through groove 30. The handle connection seat 1 has a cable channel 10 for the cable to enter the cable connection part 21 from the through groove 30. The cable connector 3 passes through the adjusting nut 4 and is inserted into the cable channel 10. It moves back and forth in the cable channel 10 as the adjusting nut 4 rotates. To facilitate the assembly of the cable, the through groove 30, the rotating mounting part 11, the adjusting nut 4 and the cable channel 10 are all provided with a notch 40 with one end open. The cable includes a cable sleeve and an internal metal wire. The cable sleeve is installed on the cable limiting part 32. The metal wire passes through the through groove 30 and the cable channel 10 and is connected to the cable connection part 21 on the handle 2.

[0036] like Figures 1-6 As shown, the handle connecting seat 1 extends towards one end of the adjusting nut 4 to form a rotating mounting part 11. An annular groove 111 is provided on the outer peripheral surface of the rotating mounting part 11. A rotating shaft 5 is provided at each end of the outer peripheral surface of the adjusting nut 4 corresponding to the annular groove 111. The outer peripheral surface of the rotating shaft 5 abuts against the annular groove 111. A rotating groove 41 connected to the rotating mounting part 11 is provided inside the adjusting nut 4. Two rotating shaft mounting holes 42 are provided at the position of the adjusting nut 4 corresponding to the annular groove 111. The rotating shaft 5 is installed in the rotating shaft mounting holes 42. A connecting hole 421 abutting against the surface of the annular groove 111 is provided at one end of the rotating groove 41. The rotating shaft 5 is installed on the adjusting nut 4 by the thread at the end. The rotating shaft in the middle clamps the annular groove 111 through the connecting hole 421, so that the adjusting nut 4 can rotate freely on the rotating mounting part 11.

[0037] like Figure 2 , Figure 3 , Figure 6As shown, a contact feedback assembly is provided between the handle connector 1 and the adjusting nut 4. The contact feedback assembly includes a spring mounting hole 6 on the handle connector 1, a spring 61, a ball 62, and a feedback adjustment screw 63 disposed in the spring mounting hole 6, as well as multiple feedback holes 64 on the surface of the adjusting nut 4. The feedback holes 64 are equidistantly arranged around the rotating groove 41 on the outer surface of the adjusting nut 4, and an arc-shaped connecting groove 641 is provided between adjacent feedback holes 64. The feedback adjustment screw 63 is threadedly connected to the spring mounting hole 6. One end of the spring 61 abuts against the feedback adjustment screw 63, and the other end abuts against the ball 62, causing the spring 61 to push the ball 62 towards one end of the adjusting nut 4. As the adjusting nut 4 rotates, the ball 62 enters or leaves the feedback hole 64. By rotating the feedback adjustment screw 63, the preload of the spring 61 can be easily adjusted, and the contact feedback force can be adjusted. At the same time, it also prevents the adjusting nut 4 from easily loosening after adjustment.

[0038] like Figures 1-6 As shown, a contact switch 7 is provided at one end of the handle connector 1 corresponding to the handle 2. The handle 2 is provided with a protrusion 71 corresponding to the contact switch 7. The handle 2 is hinged to one end of the handle connector 1. The handle connector 1 is provided with a hinge hole 12. The handle 2 is provided with a bearing mounting hole 22 that mates with the hinge hole 12. A hinge shaft 8 passes through the hinge hole 21 and the bearing mounting hole 22. Two sets of ball bearings 82 are provided in the bearing mounting hole 22. The two sets of ball bearings 82 are fixed in the bearing mounting hole 22 with an interference fit. A bushing 83 is provided between the two sets of ball bearings 82. The hinge shaft 8 passes through the hinge hole 12, the ball bearing 83, the bushing 83, the ball bearing 83, and the hinge hole 12 in sequence and is connected to the hinge nut 81.

[0039] like Figures 1-6As shown, this utility model discloses a clutch handle for quickly adjusting the travel of the pull cable, including a handle connecting seat 1, a handle 2 and a pull cable connector 3 hinged to the handle connecting seat 1, an adjusting nut 4 provided on the pull cable connector 3, the adjusting nut 4 rotatably engaging with the rotating mounting part 11 of the handle connecting seat 1 and being limited by a rotating shaft 5, the rotating mounting part 11 having an annular groove 111 on its outer circumferential surface, the adjusting nut 4 having a rotating shaft 5 on each side corresponding to the annular groove 111, the outer circumferential surface of the rotating shaft 5 abutting against the surface of the annular groove 111, allowing the adjusting nut 4 to rotate freely around the rotating mounting part 11, and the pull cable connector 3... The threaded part 31 is threadedly connected to the inner wall of the adjusting nut 4. When the adjusting nut 4 is rotated, the pull cable connector 3 moves back and forth axially within the pull cable channel 10, achieving linear adjustment of the pull cable stroke from 0 to 15 mm. Specifically, rotating the adjusting nut 4 clockwise drives the pull cable connector 3 to extend outward through the pull cable channel 10, tightening the pull cable (increasing the stroke to a maximum of 15 mm). Rotating the adjusting nut 4 counterclockwise causes the pull cable connector 3 to retract inward, loosening the pull cable (reducing the stroke to a minimum of 0 mm). The connector is also limited by the limiting step 33. When the adjusting nut 4 is rotated, the springs 62 sequentially engage for feedback. Hole 64 triggers a "click" sensation once per hole (each hole corresponds to a 2mm stroke). After adjustment, it is preferable to tighten the feedback adjusting screw 63 to increase the preload of the spring 61 and prevent the adjusting nut 4 from easily turning back. Then, grip the handle. The metal wire of the pull cable drives the pull cable connection part 21 through the through groove 30 to verify whether the stroke is smooth and without jamming. The entire process of pull cable adjustment does not require tools and can quickly adjust the pull cable. The self-limiting of the adjusting nut 4 is achieved through the contact feedback component. The contact feedback component is provided between the handle connecting seat 1 and the adjusting nut 4, including spring 61, ball 62 and adjusting screw 6. 3. The ball bearing 62 is embedded in the equidistant feedback holes 64 on the surface of the adjusting nut 4 by the spring preload. Each insertion into a feedback hole corresponds to a 2mm stroke change. Rotating the adjusting screw 63 can adjust the ball bearing clamping force to prevent the nut from loosening after adjustment. The handle 2 and the handle connecting seat 1 are elastically rotated and engaged by the hinge shaft 8 and two sets of ball bearings 82. A bushing 83 is provided between the two sets of ball bearings 82. After the hinge shaft 8 passes through the bearing, it is fixed by the hinge nut 81 to ensure that the handle 2 rotates smoothly without gaps or wobbling, improving the stability of the operation feel. At the same time, after wear, only the ball bearings 82 need to be replaced for reuse, reducing maintenance costs.
