GROUP 2 TRANSMISSION
1. STRUCTURE AND WORKING PRINCIPLE OF TRANSMISSION
As illustrated in the page 2-3, figure 1, the transmission consists of transmission housing (1), large end cover (2), reverse shaft assembly (3), input shaft assembly (5), countershaft assembly (6), output shaft (8), range gear sleeve (9) and shoe brake (12).
A hydraulic clutch is attached each to reverse shaft assembly (3), input shaft assembly (5) and countershaft assembly (6).
As illustrated in figure 2, a hydraulic clutch consists of clutch driving shaft (1), clutch housing (2), piston (3), exterior friction plate (4), interior friction plate (5), return spring (6) and clutch emptying valve (7). When flow of hydraulic oil enters head end of cylinder, piston is pushed to move forward pressing drive and driven friction plate to make driving shaft and gear to rotate, cut off hydraulic oil, and thus clutch emptying valve opens automatically to press spring (6) to return.
As illustrated in figure 2, the hydraulic clutch consists of 6 clutch drive plates and 5 driven plates. The driven plate has a 0.5 mm crown and the crown side should face piston. Gap-clearance of piston ring should be ground and its width within 0.05~0.1 mm.
