The present invention relates to a hybrid drive module capable of reducing the operating pressure when a piston pressurizes a lock-up clutch with a simple structure, and ensuring the pressure when pressurizing the lock-up clutch, the lock-up clutch being disposed in a space in which the fluid pressure of a torque converter acts, and having a small number of components and convenient assembly. This effect is achieved by providing a compensation chamber of the piston and filling the compensation chamber with a low-pressure fluid. Moreover, the low pressure fluid may also be used as a fluid for lubricating and cooling an engine clutch.
本发明涉及一种混合动力驱动模块,所述模块能以简单的结构降低活塞加压锁止离合器时的工作压力,同时,能确保对锁止离合器加压时的压力,锁止离合器配置在扭矩变换器的流体压力所作用的空间内,而且,零件数量少、方便组装。这种效果通过设置活塞的补偿室,并在该补偿室内填充低压流体来实现。而且,所述低压流体还可以用作用于润滑及冷却发动机离合器的流体。
