Description

Technical Field

[0001] The utility model relates to the field of clutches, in particular to a combined clutch pressure plate assembly. Background Art

[0002] A combined clutch usually consists of multiple components, including an input disk, a driven disk, a compression spring, a corrugated disk, etc. They transfer torque through friction, enabling power to be transmitted from one rotating shaft to another. When the load is too large, the clutch can slip, thereby protecting the system from damage. In a traditional friction clutch, the pressing force between the input disk and the driven disk is usually provided by a compression spring on the back of the driven disk. This structure is simple but has some limitations.

[0003] Since the pressure plate is in direct contact with the friction lining on the driven disk, long-term contact will cause wear, which may make the friction surface uneven, affecting the transmission effect and performance. Insufficient friction coefficient will cause slippage between the pressure plate and the driven disk, unable to effectively transmit power. This will lead to poor acceleration and power loss. In view of this technical problem, this application proposes a combined clutch pressure plate assembly. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the deficiencies existing in the prior art, and a combined clutch pressure plate assembly is proposed. A friction plate is installed at the bottom of the pressure plate body, which can increase the friction coefficient with the driven disk. A higher friction coefficient can ensure more stable power transmission during starting and shifting gears. The outer shell and the pressure plate body are connected through transmission plates and fixing bolts, which plays a protective role for the device and facilitates the assembly of the outer shell and the pressure plate body.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A combined clutch pressure plate assembly includes a pressure plate body. A friction plate is connected to the bottom of the pressure plate body through an installation component. A diaphragm spring is arranged on the top of the pressure plate body. A plurality of radial grooves are formed on the surface of the diaphragm spring. The top of the pressure plate body is connected to an outer shell through a connection component. The outer shell is located directly above the diaphragm spring. A plurality of connection grooves are formed on the top of the outer shell. Connection caps are arranged below the plurality of connection grooves and above the plurality of radial grooves. On the adjacent sides of the upper and lower connection caps, connecting rods are provided. The plurality of connecting rods are respectively sleeved inside the connection grooves of the outer shell and the radial grooves of the diaphragm spring.

[0007] Further, the installation component includes a fixed disk fixedly connected to the bottom of the pressure plate body. A rotating disk is rotatably connected to the outer periphery of the fixed disk. Three installation grooves are provided inside both the rotating disk and the outer periphery of the fixed disk. Three installation rods are arranged inside the three installation grooves, and the bottoms of the three installation rods are fixedly connected to the top end of the friction plate.

[0008] Further, engaging grooves are provided on the mutually separated sides of the three installation rods, and the inner ring of the rotating disk is arranged inside the engaging grooves.

[0009] Further, the connection component includes transmission pieces arranged at both the left and right ends of the top of the pressure plate body. The transmission pieces are in a stepped shape. The high ends of the transmission pieces are arranged at the top of the outer shell, and fixing bolts are arranged at the tops of both the high and low ends of the transmission pieces.

[0010] Further, fixing grooves are provided at the high and low ends of the transmission pieces, on the top of the pressure plate body, and on the top of the outer shell. The fixing bolts are threadedly connected inside the fixing grooves.

[0011] Further, threaded surfaces are provided at both the upper and lower ends of the outer periphery of the connecting rod, and the upper and lower connection caps are threadedly connected to the surface of the connecting rod.

[0012] Further, a positioning groove is provided at the top of the pressure plate body, and the bottom of the diaphragm spring is arranged inside the positioning groove.

[0013] The utility model has the following beneficial effects:

[0014] 1. In the utility model, a friction plate is installed at the bottom of the pressure plate body, which can increase the friction coefficient with the driven disk. The increase in the friction coefficient means that under the same pressing force, the clutch can transmit a greater torque. A higher friction coefficient can ensure smoother power transmission during starting and shifting. At the same time, the friction plate can be replaced according to the rotating disk, fixed disk, and installation rod, thereby improving the service life of the device.

[0015] 2. In the utility model, the outer shell and the pressure plate body are connected by the transmission pieces and the fixing bolts, which plays a protective role for the device and facilitates the assembly of the outer shell and the pressure plate body. By sequentially inserting the connecting rod into the connecting groove on the outer shell and the radial groove on the diaphragm spring, and then installing the connection caps at both ends of the connecting rod, it is convenient to assemble the outer shell and the diaphragm spring.
