Transmission’s input shaft assembly, countershaft assembly and reverse shaft assembly have similar construction, each of which has a key unit, hydraulic clutch, with the same construction.
Figure 4 is a diagram of hydraulic clutch. This unit consists of drive shaft (1), clutch case (2), piston (3), powder metallurgy friction plate (4), friction plate (5), return spring (6), drain valve (7).
Hydraulic oil from transmission’s control valve is directed to the tube inside the case and large end cover, then into the way (8) of drive shaft (1), then piston cavity, pushing the piston forward to to press the active and passive plate (4) and (5). Therefore, drive shaft (1) rotates along with gear (9), hydraulic oil is cut off, drain valve opens, the piston quickly returns by the force of spring (6), active and passive plate part, and gear (9) idles.
Figure 4 Diagram of hydraulic clutch
Active plate is made of copper-based metal powder, total 6 pcs. Passive plate is made of 65Mn, total 5 pcs. Concavity is 0.5 mm, convexity should face piston side as assembling. After assembly, turn the friction plate with hand to check and, if you feel tight, the spacing is too small and you need to change with a thinner one.
Poor installation of piston ring (10) and (11) and wear appeared in use adversely affects sealing condition and further operation of clutch. Therefore, it’s required to pay attention in installation of packing ring.
