Clutch Housing


Clutch Housing for the Gearbox (16 forward+8 reverse)


The clutch housing accommodates the drives of the independent PTO, Hydraulic Lift Linkage pump and a pump of the transmission hydraulic system.





1 – force-transmission shaft; 2, 9 – PTO driving shaft; 3 – clutch release shifter support; 4, 7 – collars; 5, 6, 17, 18, 23, 27 – bearings; 8 – splined bushing; 10 – PTO driven shaft; 11 – bearing; 12 – packing liner; 13, 15 – covers; 14 – bolt; 19, 26 – pinion-shaft; 20 – Hydraulic Lift Linkage and transmission pumps drive gear; 21 – spindle; 22 – axle; 24 – check ring; 25 – pinion-shaft; 28 – housing

The driving shaft (2, 9) of the independent PTO drive supported in bearings (5, 6) has two ring gears. A pinion (16) of the independent PTO drive is in constant mesh with the smaller ring gear, while a gear (20) of the pump of the transmission hydraulic system and that of the Hydraulic Lift Linkage is in mesh with the other ring gear.

The pump of the transmission hydraulic system is driven from the driving shaft (2, 9) through gears (20, 26, 25).
With the clutch engaged, the torque from the clutch actuator plates is transmitted to the gearbox primary shaft through the shaft (1) and the bushing (8).



Clutch Housing for the Gearbox (24 forward+12 Reverse)


The clutch housing (30) accommodates the driving and driven shafts with the pinions fitted on them and drives of the oil pumps of the Hydraulic Lift Linkage and transmission hydraulic system. The driving shaft (4) is supported in two bearing assemblies. The shaft has a ring gear and splines, on which the pinion (5) is seated. The pinion (5) causes the rotation of the gear (19) of the driven shaft of the independent PTO drive (18) and gear (8) for driving the oil pumps.

The power shaft (1) is passed inside the shaft (4) and transmits the torque from the clutch to the gearbox primary shaft through the splined bushing (6). The driven shaft (18) is supported in two bearings (17, 27) in the housings of the clutch and gearbox. The driven gears (19) and (24) of the two-speed drive of the independent PTO are fitted on the shaft in the needle bearings (25).





1 – power shaft; 2 – bracket, 3,10, 14, 17, 25, 27 – bearings; 4 – driving shaft; 5 – pinion; 6 – splined bushing; 7 – cover; 8 – Hydraulic Lift Linkage and transmission pumps drive gear; 9, 15 – pinion shaft; 11 – nut; 12 -pinion shaft; 13 – axle; 16 – collar; 18 – driven shaft; 19 – gear; 20 – fork; 21 – roller; 22 – cover; 23 – toothed coupling; 24 – gear; 26 – spindle; 28 – roller; 29 – fork; 30 – housing.

The fixed connection of the gears (19, 24) with the shaft is achieved by means of the toothed coupling (23), with is moved by means of the fork (20) and shaft (21).
The Hydraulic Lift Linkage is driven by means of the pin-ion (5) and gear (8) and the pump of the transmission hydraulic system is driven through the pinion (5), gear (8) and shafts (15) and (12).
