A clutch wear limit warning device

Abstract

This utility model belongs to the field of clutches and relates to a clutch wear limit early warning device, including a piston cylinder. The piston cylinder includes an outermost cylinder barrel, inside which a piston is sleeved. Inside the piston, a bearing is sleeved. A cylinder bottom cover is connected to the bottom of the cylinder barrel. A right-angle test piece is connected to the side of the piston away from the cylinder bottom cover. A displacement sensor for detecting the position of the right-angle test piece is connected to the outer wall of the cylinder barrel. This utility model, by connecting a right-angle test piece to the piston and a displacement sensor connected to the outer wall of the cylinder barrel, detects the displacement distance of the right-angle test piece. When the steel plate or friction plate wears thinner, the displacement distance of the right-angle test piece increases, thereby indicating the wear condition of the steel plate and friction plate. When the observed displacement distance of the right-angle test piece reaches a threshold, replacement and maintenance work is performed, thus greatly improving the safety of the equipment using this utility model.

Description

Technical Field

[0001] This utility model belongs to the field of clutches and relates to a clutch wear limit warning 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 control the engagement and disengagement. Piston cylinder-driven dry clutches facilitate automated control and are therefore more widely used. However, after prolonged use, the steel plates and friction plates inside the clutch gradually wear down, becoming thinner. This increases the gap between the steel plates and friction plates. Given the limited piston cylinder stroke, the contact between the steel plates and friction plates becomes less tight, and after a certain degree of wear, the flatness of the friction plates is affected, leading to sudden clutch failure and significant losses in equipment operation and production. Therefore, it is necessary to monitor the wear of the steel plates and friction plates to prevent such accidents. Utility Model Content

[0003] This invention addresses the problem of wear and thinning of steel sheets and friction plates mentioned above by proposing a clutch wear limit early warning device.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a clutch wear limit warning device, comprising a piston cylinder, the piston cylinder comprising 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 right-angle test piece connected to the side of the piston away from the cylinder bottom cover, and a displacement sensor for detecting the position of the right-angle test piece connected to the outer wall of the cylinder barrel.

[0005] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0006] This invention connects a right-angle test piece to the piston and a displacement sensor to the outer wall of the cylinder. The displacement sensor detects the displacement distance of the right-angle test piece. When the steel sheet and friction plate wear thinner, the displacement distance of the right-angle test piece increases, thus indicating the wear condition of the steel sheet and friction plate. When the displacement distance of the right-angle test piece reaches the threshold, replacement and maintenance work is carried out, thereby greatly improving the safety of the equipment using this invention.

[0010] 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.

[0011] 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.

[0012] like Figure 1 As shown, in order to monitor the wear of steel sheet 8 and friction plate 9, this utility model provides a clutch wear limit early warning device, including a piston cylinder, the piston cylinder including the outermost cylinder barrel 1, a piston 2 sleeved inside the cylinder barrel 1, a bearing 3 sleeved inside the piston 2, a cylinder bottom cover 4 connected to the bottom of the cylinder barrel 1, the piston 2 can drive the bearing 3 to move outward, a right angle test piece 5 is connected to the side of the piston 2 away from the cylinder bottom cover 4, a displacement sensor 6 for detecting the position of the right angle test piece 5 is connected to the outer wall of the cylinder barrel 4, and the end of the right angle test piece 5 is above the displacement sensor 6.

[0013] This utility model discloses the structure of a partial clutch. Based on the piston cylinder, a sliding sleeve 7 is sleeved inside the bearing 3. The bearing 3 can drive the sliding sleeve 7 to move outward. A steel plate 8 is connected to the end of the sliding sleeve 7 away from the bottom cover 4 of the oil cylinder. A friction plate 9 is provided at the end of the steel plate 8 away from the sliding sleeve 7.

[0014] The principle of this invention is as follows: Since the piston 2 will only stop moving after the steel sheet 8 and the friction plate 9 are pressed together, after the steel sheet 8 and the friction plate 9 are worn, the thickness of the stacked steel sheet 8 and the friction plate 9 will decrease, and the piston 2 will move longer. Therefore, the right angle test piece 5 detected by the displacement sensor 6 will move longer. Thus, the wear condition of the steel sheet 8 and the friction plate 9 can be determined based on the movement distance of the right angle test piece 5.

[0015] 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.
