离合器的冷却构造
摘要：
一种前进离合器(4)的冷却构造，设于驱动板(42)的衬片部件(43)压接于从动板(46)，限制驱动板(42)和从动板(46)的相对旋转，其中，在周向邻接的衬片部件(43、43)之间形成有通过离心力向外径侧移动的润滑油(OL)流通的点状槽为，通过点状槽(421)的润滑油(OL)的流量为可将驱动板(42)和从动板(46)冷却到上限温度(Tmax)以下的最小流量的宽度(a)，将点状槽(421)的宽度(Wa)的上限设定为，通过点状槽(421)的润滑油(OL)中的空气含有率为利用该空气含有率的润滑油(OL)可将驱动板(42)和从动板(46)冷却到上限温度(Tmax)以下的最大含有率的宽度(b)。(421)，将点状槽(421)的宽度(Wa)的下限设定
摘要（英）：

In this cooling structure in a forward clutch (4), a facing member (43) provided on a drive plate (42) presses against a drive plate (46), restricting relative rotation between the drive plate (42) and the drive plate (46). A dot groove (421) is formed between facing members (43, 43) adjacent in the circumferential direction, and a lubricant (OL) flows through the dot groove (421), moving radially outwards due to centrifugal force. The lower limit of the width (Wa) of the dot groove (421) is set to a width (a) such that the lubricant (OL) passing through the dot groove (421) moves at the minimal flow speed that can cool the drive plate (42) and the drive plate (46) to a temperature less than or equal to a maximum temperature (Tmax), and the upper limit of the width (Wa) of the dot groove (421) is set to a width (b) such that the air content ratio in the lubricant (OL) passing through the dot groove (421) is the maximum at which the lubricant having said air content ratio can cool the drive plate (42) and the drive plate (46) to a temperature less than or equal to maximum temperature Tmax.
