    • The invention relates to a method for controlling both the coolant supply and the lubricant supply to a clutch of a motor vehicle having an automatic transmission, in particular for controlling the coolant supply and the lubricant supply of a double clutch of an automatic double-clutch transmission. Various operational states of the transmission can thereby be controlled via a gearshift lever. The coolant flow supplied to the clutch during the operation of the motor vehicle can be interrupted intermittently for certain operational states of the transmission, or for certain gear shifts within the transmission, thus realizing the coolant pause. Drag torques are prevented in that the cooling and lubrication of the clutch are carried out using the same fluid, that is, a coolant, in particular a cooling oil, from a single coolant circuit; in that, when the gearshift lever is in the parking brake (P) position or the neutral gear (N) position and the corresponding operational state is realized in the transmission, or that, when certain shift position changes are realized within the transmission and the speed selector actions required therefor are executed in the transmission, a coolant pause is realized, and for the duration of the coolant pause, no effective quantity of a fluid volume flow for cooling is fed to the clutch, while during this coolant pause for lubrication purposes of the clutch components, a ramp or pulse feed of a fluid volume flow for lubricating the clutch components is realized, at least intermittently.
    • 本发明涉及一种用于控制两者的冷却剂供应和润滑剂供应到机动车辆的离合器具有在自动变速器中,特别是用于控制冷却剂供给和自动双离合器变速器的双离合器的润滑剂供给的方法 , 变速器的各种操作状态可以由此经由换档杆来进行控制。 机动车辆的外科手术过程中供给至离合器的冷却剂流可以间断,以便传输,或用于传输内的某些换档的某些运行状态被中断,从而实现了冷却剂断裂。 曳转矩防止DASS模具冷却和离合器的润滑进行了使用相同的流体,所做的是,冷却剂,尤其是冷却油,从一个单一的冷却剂回路; 在于,当换档杆处于驻车制动器(P)位置或空档(N)位置和相应的操作状态是这样实现的传输,或者,当某些换档位置改变变速器和内实现 为此所需的在传输执行的速度选择操作中,冷却剂断裂得以实现,并用于冷却剂断裂的持续时间,用于冷却流体的体积流量的没有有效的量被供给到离合器,同时为了润滑此冷却剂中断期间 离合器组件,用于润滑离合器组分的流体的体积流量的坡道或脉冲的进料实现,至少间歇。
