Accompanying drawing explanation
Fig. 1 cross-sectional view of the present utility model;
In figure: front case 1, input shaft 2, execution piston 3, release bearing 4, diaphragm spring 5, friction pair assembly 6, platen 7, output shaft 8, rear end cover 9, supporting sleeve 10.
Embodiment
Below in conjunction with Figure of description, embodiment of the present utility model is further illustrated.
Consult shown in Fig. 1, clutch of the present utility model is a kind of wet clutch, comprises front case 1 (band oil circuit control, cooling oil path), input shaft 2, performs piston 3, release bearing 4, diaphragm spring 5, friction pair assembly 6 (friction plate, steel disc), platen 7, output shaft 8, rear end cover 9 and supporting sleeve 10.Wherein said input shaft 2, execution piston 3, release bearing 4, diaphragm spring 5, friction pair assembly 6, platen 7, output shaft 8 and support 10 cover are all positioned in the middle of front case 1 and rear end cover 9, rear end and the supporting sleeve 10 of input shaft 2 pass through spline joint, it is inner that output shaft 8 front end is sleeved on input shaft 2 by 2 needle bearings, rear side is connected with rear end cover by deep groove ball bearing, clutch output shaft and transmission input shaft, by spline joint, realize moment of torsion transmission;
Friction means comprises steel disc, friction plate and supporting sleeve 10.Supporting sleeve 10 is connected with input shaft 2 by spline, and friction plate is connected with supporting sleeve 10 is castellated, and as the drive end of friction pair, steel disc is connected with output shaft 8 is castellated, as the driven end of friction pair.
Described diaphragm spring 5 is between release bearing 4 and platen 7, and release bearing 4 inner ring promotes diaphragm spring 5 inner ring, and diaphragm spring 5 extrudes platen 7;
Described front case 1 inside is processed with high voltage control oil and cold oil two oil circuits.
Oil circuit refers to the elongated hole boring two diameter 6mm on front case, and high voltage control oil flow to execution piston nose through this elongated hole.
Wherein, described supporting sleeve 10 and input shaft 2 are by spline joint, and its shoulder place and snap ring are fixed, and ensure its axial restraint;
Perform piston 3, release bearing 4 between front case 1 and diaphragm spring 5.An airtight cavity is formed between described execution piston 3 and front case 1, control high pressure oil and enter execution piston nose by front case 1 internal oil passages, promote to perform piston to move to right, and then promote release bearing 4 outer ring, release bearing entirety moves to right, release bearing inner ring promotes diaphragm spring 5 separation finger position, due to diaphragm spring 5 leverage, diaphragm spring 5 moves to right and extrudes platen 7, reduce steel disc and friction plate gap, along with the pressure increase between friction pair, realize clutch master and slave moved end synchronization, realize clutch in conjunction with action.When oil pressure reduces, diaphragm spring 5 reaction push-press separation bearing 4, counter the pushing away of release bearing performs piston 3, pushes back fuel tank by counter for execution fluid, and friction plate and steel disc gap increase simultaneously, and speed discrepancy appears in the driving and driven end of clutch, realizes clutch separation action.
Clutch's jointing process, master and slave moved end reaches synchronization by friction pair extrusion friction, can produce waste heat in process, therefore this clutch need force cooling.Cold oil enters input shaft 2 internal oil passages by front case 1 internal cooling oil circuit, and by the effect of clutch rotary centrifugal force, cold oil is evenly distributed on friction pair assembly 6 surface, realizes surface of friction pair refrigerating function.
