变速器装置及装载有该变速器装置的车辆
摘要：
当变速杆位于倒退(R)位置时，通过来自手控阀(58)的R位置用输出口(58c)的倒退压力(PR)使制动器(B2)接合，并通过来自线性螺线管(SLC3)的SLC3压力使离合器(C3)接合，从而形成倒退1速的状态。当变速杆位于空档(N)位置时，通过将来自线性螺线管(SLC3)的SLC3压力供给到制动器(B2)而代替离合器(C3)而使制动器(B2)接合，从而形成空档的状态。由此，不必设置用于使制动器(B2)接合的专用线性螺线管。因此，可抑制由另外设置线性螺线管引起的液压回路(50)的流量消耗(能量消耗)的增加、提高装置整体的能量效率，并可使装置整体小型化。
摘要（英）：

When a shift lever is in the reverse (R) position, a brake (B2) is engaged by reverse pressure (PR) from an output port (58c) for the R position of a manual valve (58), and a clutch (C3) is engaged by the SLC3 pressure from a linear solenoid (SLC3), and the one shift backward state is produced. When the shift lever is in the neutral (N) position, the brake (B2) is engaged by supplying SLC3 pressure from the linear solenoid (SLC3) to the brake (B2) instead of the clutch (C3), and the neutral state is produced. Thus, a dedicated linear solenoid does not have to be provided to engage the brake (B2). As a result, an increase in the consumption flow rate (consumed energy) in a hydraulic path (50) caused by the placement of a separate linear solenoid is suppressed so that the energy efficiency of the device as a whole can be improved and a more compact construction can be envisaged.
