Description

Technical Field

[0001] This utility model belongs to the field of clutches and relates to an emergency clutch engagement device. Background Technology

[0002] Existing dry clutches can be divided into two types based on their driving method: one type uses manual power and a lever mechanism to control the engagement and disengagement of the dry clutch; the other type uses hydraulic or pneumatic power and a piston cylinder to drive the clutch. Using a piston cylinder to drive the dry clutch facilitates automated control and therefore has a wider range of applications. However, as the piston cylinder is used for a longer period, the internal seals gradually wear down. When the wear reaches a certain level, the piston cylinder thrust becomes unstable, leading to clutch failure. Therefore, there is an urgent need to develop an emergency device to provide emergency repair in case of clutch failure. Utility Model Content

[0003] This invention addresses the aforementioned problem of sudden clutch failure by providing an emergency clutch engagement device for clutches using pneumatically driven piston cylinders.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a clutch engagement emergency device, comprising a clutch housing and a piston cylinder fixed on the clutch housing. The piston cylinder includes an outermost cylinder barrel, a piston sleeved inside the cylinder barrel, a bearing sleeved inside the piston, a cylinder bottom cover connected to the bottom of the cylinder barrel, a through hole provided in the cylinder bottom cover, a threaded hole provided on both sides of the clutch housing, the through hole and the threaded hole being coaxially aligned, an emergency pin being slidably connected in the through hole, and a set screw being threadedly connected in the threaded hole.

[0005] Preferably, the set screw is located on the side of the clutch housing away from the bottom cover of the cylinder.

[0006] Preferably, the set screw is threaded with a nut, which presses against the clutch housing.

[0007] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0008] This invention features a set screw. When the piston thrust is unstable, causing unstable contact between the steel plate and the friction plate, the set screw on the clutch housing can be manually rotated to push the emergency pin and piston to move, ensuring close contact between the steel plate and the friction plate and preventing accidents.

[0009] This utility model has a simple structure, is easy to manufacture and use, and is therefore suitable for widespread application. Attached Figure Description

[0010] To more clearly illustrate the technical solutions of the embodiments of this utility model, the drawings used in the description of the embodiments will be briefly introduced below. Obviously, the drawings described below are some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0011] Figure 1 This is a schematic diagram of the clutch structure for applying this utility model.

[0012] In the above figures, 1. Clutch housing; 2. Cylinder; 3. Piston; 4. Bearing; 5. Sliding sleeve; 6. Cylinder bottom cover; 7. Emergency pin; 8. Set screw; 9. Seal; 10. Steel plate; 11. Friction plate; 12. Nut. Detailed Implementation

[0013] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0014] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0015] like Figure 1 As shown, in order to provide emergency repair in case of piston cylinder failure in the clutch, this utility model provides a clutch engagement emergency device, including a clutch housing 1 and a piston cylinder fixed on the clutch housing 1. The piston cylinder includes an outermost cylinder barrel 2, a piston 3 sleeved inside the cylinder barrel 2, and a bearing 4 sleeved inside the piston 3. The piston 3 is used to output thrust and can push the bearing 4 outward. A cylinder bottom cover 6 is connected to the bottom of the cylinder barrel 2. The cylinder bottom cover 6 is provided with several through holes. The clutch housing 1 is provided with several threaded holes penetrating both sides. Each through hole is coaxially aligned with a threaded hole. An emergency pin 7 is slidably connected in the through hole, and a set screw 8 is threadedly connected in the threaded hole. A sealing element 9 is provided on the piston 3 and the emergency pin 7 to improve the sealing performance.

[0016] This utility model also discloses the structure of a partial clutch: Based on the aforementioned piston cylinder, a sliding sleeve 5 is fitted inside the bearing 4. The bearing 4 can drive the sliding sleeve 5 to move outward. A steel plate 10 is connected to the end of the sliding sleeve 5 away from the clutch housing 1. A friction plate 11 is provided on the side of the steel plate 10 away from the sliding sleeve 5. The steel plate 10 and the friction plate 11 are respectively connected to the components that need to be transmitted. When the steel plate 10 and the friction plate 11 are in close contact, transmission is formed; when the steel plate 10 and the friction plate 11 are separated, the transmission is discontinued.

[0017] The method of use of this utility model is as follows: When the seal 9 of the piston 3 is normal, the emergency pin 7 does not contact the piston 3. When the piston 3 is damaged due to excessive movement, the piston 3 thrust becomes unstable. Therefore, the set screw 8 is manually rotated to gradually penetrate into the screw hole, thereby pushing the emergency pin 7 to move. After one end of the emergency pin 7 overlaps with one side of the piston 3, it further pushes the piston 3 to move, and finally makes the steel plate 10 and the friction plate 11 in close contact, thereby stabilizing the transmission.

[0018] Furthermore, the set screw 8 is located on the side of the clutch housing 1 away from the cylinder bottom cover 6.

[0019] Furthermore, the set screw 8 is threadedly connected to a nut 12, which presses against the clutch housing 1 to prevent the set screw 8 from moving axially due to vibration.

[0020] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
