Description

Technical Field

[0001] The utility model relates to the technical field of automobile clutch plates, in particular to an automobile clutch plate with active wear reminder function. Background Art

[0002] Some clutch plates, when the clutch plates are severely worn, will rub against the copper base plate of the clutch plate to produce a sharp metal friction sound. It is not clear when the clutch plates will be replaced. In addition, there are abnormal noises in the car, and for a while, it is not known what is wrong with the car.

[0003] In this regard, China applied for patent number: CN218625180U, which discloses a car clutch plate with active wear reminder, including a mounting through hole, a sleeve, a sleeve, a metal ball, a latch, a threaded groove, a spring, a button battery assembly and a trigger alarm.

[0004] However, in actual use, since the degree of wear of the grinding discs varies during use, the degree of wear will not be uniform. Therefore, it is not possible to fully detect and remind through the design of a set of reminder components. When the worn area is not on the same plane as the reminder component, no reminder can be given, which has certain limitations. Therefore, it has become an urgent problem to be solved to perfect and improve the above-mentioned problems. Utility Model Content

[0005] The purpose of the utility model is to provide a car clutch plate with active wear reminder, so as to solve the problem raised in the above background technology that the wear degree of the wear plate is different during use, and thus the wear degree of the place will not be uniform. Therefore, it is not possible to fully detect and remind only by using a set of reminder components. When the worn part is not on the same plane as the reminder component, no reminder can be given, which has certain limitations.

[0006] To achieve the above object, the utility model provides the following technical solutions: an automobile clutch plate with active wear reminder, comprising a clutch plate copper substrate, an assembly hole is provided inside the clutch plate copper substrate, a grinding plate body is provided on the top surface of the clutch plate copper substrate, a pit is provided on the surface of the grinding plate body, and heat dissipation holes are provided on the left and right side surfaces of the grinding plate body;

[0008] Preferably, a mounting rod is provided on the lower surface of the moving cylinder, and a contact plate is fixedly connected to the lower surface of the mounting rod.

[0009] Preferably, the inner bottom wall of the bottom tube is fixedly connected to a base, and the top surface of the base is provided with a reminder tube.

[0010] Preferably, a pressure sensor is provided on the top surface of the reminder tube, and the pressure sensor is installed below the abutment plate.

[0011] Preferably, a contact plate is provided on the top surface of the moving cylinder, and a groove is formed on the top surface of the contact plate.

[0012] Preferably, a rotating column is inserted and installed on the inner side wall of the contact plate, and a metal ball is arranged on the back side of the rotating column.

[0013] Preferably, the metal balls and the grooves are adapted to each other, and five groups of the metal balls are provided.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. The automobile clutch plate with active wear reminder has a clutch plate copper base plate, an assembly hole, a grinding plate body, a pit, a bottom cylinder, a spring lifting cylinder, a moving cylinder, a support ring, a mounting rod, a contact plate, a base and a reminder cylinder. When in use, the design of the pit can prevent the grinding plate body from cracking. Then the size of the grinding plate body is higher than the contact plate. When the grinding plate body is worn, the surface of the contact plate will contact the brake disc, so that the contact plate can be squeezed. Then the contact plate will drive the moving cylinder to move downward, and then the support ring will press the spring lifting cylinder downward. Then the moving cylinder will drive the mounting rod and the contact plate to move downward as a whole, and then the contact plate will contact the pressure sensor. When the pressure sensor is under pressure, the pressure sensor sends a signal to the instrument panel to remind the driver. At the same time, the contact plate in this design is in the same plane as the grinding plate body. When the grinding plate body is worn, it will contact the top surface of the contact plate, which solves the problem that only one wear part of the grinding plate body can be reminded in the past, and reflects the practicality of the design.

[0016] 2. The automobile clutch plate with active wear reminder has a resistance plate, a groove, a rotating column and a metal ball. When in use, first a groove is opened on the top surface of the resistance plate, and then a metal ball is installed inside the groove. When the wear plate body is worn, the brake disc will be resisted by the metal ball, so that the metal ball can rub against the brake disc and have a certain friction effect. The metal ball can also make the subsequent wear detection more sensitive, reflecting the functionality of the design. BRIEF DESCRIPTION OF THE DRAWINGS
