Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, specifically to an improved structure of an automotive friction plate clutch. Background Technology

[0002] The existing friction plate components in automotive dual-clutch transmissions generally have the following defects: the original parts K1 and K2 typically consist of 3-4 friction plates, one flange plate, and four steel plates, resulting in insufficient friction area. As a result, after a new car has traveled 30,000-50,000 kilometers, the friction coefficient of the friction surface weakens, leading to low transmission efficiency, lack of power, slippage, and other problems. Utility Model Content

[0003] In view of the above-mentioned technical deficiencies, the purpose of this utility model is to provide an improved structure for an automotive friction plate clutch to improve the transmission efficiency of the automotive clutch.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The present invention provides an improved structure for an automotive friction plate clutch, including a K1 clutch module and a K2 clutch module. The K1 clutch module includes a flange plate one disposed inside the K1 clutch drum, and K1 friction plates and K1 steel plates arranged alternately on the flange plate one. The number of K1 friction plates and K1 steel plates is five, and the working clearance of the K1 clutch module is 2.1mm. The K2 clutch module includes a flange plate two disposed inside the K2 clutch drum, and K2 friction plates and K2 steel plates arranged alternately on the flange plate two. A piston return spring is sleeved on the K2 friction plates. The number of K2 friction plates and K2 steel plates is five, and the working clearance of the K2 clutch module is 2.0mm.

[0005] Preferably, the K1 friction plate has a thickness of 1.8 mm and a diameter of 185.8 mm, the K1 steel plate has a thickness of 1.5 mm, and the flange plate has a thickness of 2.5 mm.

[0006] Preferably, the end of the K1 clutch drum is provided with a K1 retaining ring groove, and a K1 baffle is embedded in the K1 retaining ring groove.

[0007] Preferably, the outer diameter of the K2 friction plate is 137.73 mm.

[0008] Preferably, the end of the K2 clutch drum is provided with a K2 retaining ring groove, and a K2 baffle is embedded in the K2 retaining ring groove.

[0009] The beneficial effects of this utility model are as follows: By changing the thickness and number of friction plates and steel plates of the K1 clutch module, and retaining the piston return spring on the friction plates of the K1 clutch module, the contact surface width of the friction plates is changed, thereby enhancing the friction effect of the overall structure and improving the transmission efficiency.
