Description

Technical Field

[0001] This utility model relates to the field of gearbox technology, and in particular to a multi-stage buffer clutch assembly for a gearbox. Background Technology

[0002] The patent publication number CN206309812U discloses a manual clutch electric window gearbox structure. By pressing the waist-shaped plate, the stepped column is driven to push the clutch gear and the reduction gear set to separate, avoiding the phenomenon that the driving gear cannot rotate because it is connected to the motor. At the same time, a spring that is compressed is provided between the lower end face of the waist-shaped plate and the bottom of the groove, so that after pressing the waist-shaped plate, the waist-shaped plate can be reset by the spring under the pressure of the compressed force, which facilitates the reset after the clutch gear is separated.

[0003] In mechanical transmission systems, the clutch gear, as a key power switching component, works by engaging or disengaging with the gear set inside the gearbox through axial displacement. When power transmission needs to be cut off, the operator must continuously apply a certain axial thrust to the clutch gear to completely disengage it from other gears in the gearbox. This requires the operator to maintain manual force for a long time during use, which can lead to muscle fatigue. Therefore, this solution proposes a multi-stage buffer clutch assembly for gearboxes to solve the above problems. Utility Model Content

[0023] 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.

[0024] This utility model provides, for example Figure 1-4 Shown:

[0025] Example 1: A multi-stage buffer clutch assembly for a gearbox, applied to gearbox housing 1, includes:

[0026] Drive shaft 4, which is inserted and connected inside housing 1;

[0027] The clutch gear 2 drives the shaft 4 and a positioning bearing 3 is sleeved in the middle. The clutch gear 2 is sleeved on the outer wall of the positioning bearing 3.

[0028] Push component 5 is located at one end of drive shaft 4 and is used to push clutch gear 2;

[0029] Positioning component 6 is located at the other end of drive shaft 4. Positioning component 6 includes adjusting block 605 located at the other end of drive shaft 4. Multiple adjusting holes 603 are provided on one side of adjusting block 605. A limiting block 604 is inserted into the interior of one of the adjusting holes 603. A rotating component 7 is provided on one side of limiting block 604.

[0030] It should be noted that the positioning bearing 3 is an existing ball bearing, used to connect the clutch gear 2 and the drive shaft 4, so that the clutch gear 2 can rotate on the drive shaft 4. In use, the clutch gear 2 is moved by the adjusting block 605. After adjusting to the desired position, the limiting block 604 is inserted into the corresponding adjusting hole 603. The position of the clutch gear 2 is fixed by the blocking of the limiting block 604, so as to avoid the need for the operator to press the clutch gear 2 continuously during use.

[0031] Specifically, the pushing component 5 includes a movable frame 501 fixedly connected to one end of the driving shaft 4, a fixed cylinder 502 fixedly connected to the inner wall of the back of the housing 1, the movable frame 501 being inserted into the inside of the fixed cylinder 502, a spring 504 being provided on the back of the movable frame 501, and a first buffer pad 503 being fixedly connected to the back of the movable frame 501.

[0032] It should be noted that the fixed cylinder 502 is a cylinder with a cylindrical hole in the middle, and the hole is adapted to the movable frame 501, so that the movable frame 501 can slide in the middle of the fixed cylinder 502, and the fixed cylinder 502 restricts the movement direction of the movable frame 501. The spring 504 is located between the movable frame 501 and the housing 1, and is used to push the movable frame 501 towards the side of the drive shaft 4 during use. The first buffer pad 503 is made of rubber. When the movable frame 501 moves towards the side of the housing 1, the first buffer pad 503 absorbs the impact force of the movable frame 501 on the housing 1.

[0033] Specifically, a connecting block 601 is fixedly connected to the front of the drive shaft 4, an adjusting block 605 is fixedly connected to the front of the connecting block 601, the adjusting block 605 is inserted into the front of the housing 1, and a second buffer pad 602 is fixedly connected to the front of the connecting block 601.

[0034] It should be noted that the cross-section of the adjustment block 605 is square, and the adjustment block 605 is inserted and connected to the front of the housing 1. The housing 1 restricts the rotation of the adjustment block 605, and the adjustment block 605 restricts the rotation of the shaft 4. The second buffer pad 602 is made of rubber. During use, the second buffer pad 602 absorbs the impact of the connecting block 601 on the housing 1.

[0035] Example 2: Rotating component 7, applied to the multi-stage buffer clutch assembly in Example 1;

[0036] Specifically, the rotating component 7 includes a connecting rod 704 fixedly connected to the back of the limiting block 604, the connecting rod 704 being inserted through the front of the housing 1, a rotating block 703 fixedly connected to the back of the connecting rod 704, a torsion spring 702 provided on the back of the rotating block 703, a fixing frame 701 fixedly connected to the inner wall of the front of the housing 1, the torsion spring 702 and the rotating block 703 being inserted through the inside of the fixing frame 701, and a knob 705 fixedly connected to the front of the limiting block 604, the knob 705 being used to rotate the limiting block 604.

[0037] It should be noted that the limiting block 604 is fitted to the front of the housing 1, and the rotating block 703 is fitted to the inner wall of the back of the housing 1. A connecting rod 704 is fixedly connected to the side opposite to the limiting block 604 and the rotating block 703, and the connecting rod 704 is inserted through the front of the housing 1. Through this design, the positions of the limiting block 604, the connecting rod 704 and the rotating block 703 are fixed, while allowing the three to rotate on the front of the housing 1. The torsion spring 702 is set on the back of the rotating block 703. Driven by the torsion spring 702, after the limiting block 604 is rotated and then the rotation of the limiting block 604 is released, the limiting block 604 can return to the inside of the adjustment hole 603.

[0038] 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.
