AI Technical Summary

Problems solved by technology

However, electronically controlled valves tend to be costly and error prone
In addition, due to the continuous mechanical wear that occurs over the life of the clutch, the control and timing of the control valves require frequent adjustments, thereby increasing operating costs

Embodiment Construction

[0039] Figure 1a to Figure 1c Details of a wet clutch assembly 1 according to the invention are schematically shown. More specifically, Figure 1a to Figure 1c Different configurations of the wet clutch assembly 1 are shown during the filling phase. The assembly 1 may find application in a transmission of a motor vehicle, in particular an off-highway vehicle such as, for example, a mining vehicle, earth moving machine, material handling vehicle or agricultural vehicle. Here and in the following, repeated features are denoted by the same reference numerals.

[0040] The wet clutch assembly 1 includes a clutch drum 2, a first shaft 3 (also called a drum shaft), a second shaft 4 (also called a clutch gear), a clutch pack 5, an end plate 6, a first biasing member 7 and a driven A clutch actuating piston 8 is movably arranged inside the clutch drum 2 . The assembly 1 can be arranged symmetrically or substantially symmetrically with respect to the clutch axis 9 . That is, Fi...

Abstract

The invention relates to a wet clutch assembly (1; 100), comprising: a clutch drum (2); a clutch chamber (10) formed inside the clutch drum (2); a clutch actuating piston (8), the clutch actuating piston (8) is movably disposed inside the clutch drum (2) and configured to be actuated by means of hydraulic pressure in the clutch chamber (10); and a fluid line (14), the fluid A line (14) extends at least partially through the clutch actuating piston (8), the fluid line (14) providing fluid communication with the clutch chamber (10) for filling the clutch chamber ( 10).

Description

technical field [0001] The present invention mainly relates to a wet clutch assembly. Wet clutch assemblies of the type presently described may find application in transmissions for motor vehicles, particularly for off-highway vehicles such as mining vehicles, material handling vehicles and agricultural vehicles. Background technique [0002] A wet clutch generally includes a clutch drum forming a clutch chamber, a clutch pack disposed inside the clutch drum and including a plurality of friction plates, and a clutch piston movably disposed inside the clutch drum. By increasing the hydraulic pressure in the clutch chamber, the clutch piston can be actuated to force the friction plates into engagement to rotationally lock the clutch drum to the drive shaft. During a shift, the amount of torque transmitted through the clutch is determined by the amount of fluid and hydraulic pressure in the clutch chamber. That is, shift quality critically depends on precisely controlling the...
