求翻译。。好心人帮下忙。。。

In a multi-plate clutch, a power is transmitted by engaging a plurality of friction engaging elements disposed within a clutch housing with each other. Within the clutch housing, a piston movable in an axial direction is provided for applying an axial urging force to the friction engaging elements to engage them with each other.
[0005] In the multi-plate clutch, it is designed so that driven plates (separator plates) and drive plates (friction plates), which serve to act as the friction engaging elements, are alternately arranged in an overlapped fashion, whereby the multi-plate clutch is engaged (tightened) or disengaged (released) by engaging the friction engaging elements with each other by the urging force of the piston or disengaging the friction engaging elements from each other.
[0006] When the piston of the multi-plate clutch urges the driven plates, due to a difference in stress between pawl portions (spline portions) and non-pawl portions of the driven plates, heat spots are generated. The heat spots are black spots generated on surfaces of the driven plates (separator plates) by means of engagement with high heat load. Since the heat spot portion is convex, the heat spot may attack the friction material. Accordingly, the heat spot may cause shudder or may affect a bad influence upon the operation and endurance of the clutch.
[0007] Further, if the splines of the driven plates are not positioned equidistantly, when the piston of the multi-plate clutch urges the driven plates, since there is difference in rigidity between the spline portions and non-spline portions of the driven plates, the driven plates may be deformed, with the result that the heat spots may partially be generated on urging surfaces corresponding to the non-spline portions.
[0008] In order to suppress the heat spot, Japanese Patent Application Laid-open No. 9-287622 (1997) discloses an arrangement in which, in order to make temperatures between plates uniform, thicknesses of driven plates are reduced steppingly from the driven plate nearest to a piston.
[0009] However, as shown in the above-mentioned Japanese Patent Application Laid-open No. 9-287622, the fact that a plurality of driven plates having different thicknesses are prepared for one multi-plate clutch may lead in increase in cost, thereby causing a new problem.

在一个多片式离合器，电源是经由聘请聘请在相互摩擦离合器住房出售多个元素。离合器壳体内，在轴向方向移动活塞提供申请要求的轴向力的摩擦从事分子进行接触对方。

[0005]在多片离合器，它的设计，使从动盘（分隔板）和驱动板（摩擦片），它们的作用，作为从事元素的摩擦，交替排列在一个重叠的方式，即多片式离合器是从事（收紧）或脱离（释放）聘用由活塞敦促部队从事的摩擦与每个其他元素或搞脱离摩擦从每个其他元素。

[0006]当多片式离合器从动盘活塞敦促，由于部分之间的棘爪（样条的部分）和从动盘非棘爪部分应力差，热斑点产生。热点上的驱动板的热负荷高的参与方式（分隔板）表面产生的黑点。由于部分是凸的热点，热斑可能攻击摩擦材料。因此，可能导致热点不寒而栗或可能影响一后的运作和离合器的耐力不良的影响。

[0007]此外，如果驱动板的花键的位置不等距，当多片离合器从动盘活塞敦促，因为在刚性花键之间的差额部分和从动盘非花键部分，从动盘可能会变形，以致热点可能部分表面上要求相对应的非样条的部分生成的结果。

[0008]为了抑制热斑，日本专利申请下岗开号9-287622（1997年）中披露的安排，以使板块之间的温度均匀，驱动板的厚度减少steppingly从驱动板最接近活塞。

[0009]然而，在上述提到的日本专利申请下岗开号9-287622所示，一个有多个不同厚度的驱动板是一个多片式离合器准备在事实上可能导致成本增加，从而造成一个新问题。
