摘要： In an automatic transmission, a small-capacity second clutch that does not engage for reverse drive is mounted forward of a counter drive gear, and the other engaging elements of relatively larger capacity, that is, first and third clutches and first to third brakes, are disposed rearward of the counter drive gear, so that an axially extending space is formed between the counter drive gear and the second clutch, which space is utilized to accommodate a parking gear. Such an arrangement of engaging elements allows the counter shaft to be placed closer to the input shaft without the parking gear interfering with the second clutch, thereby enabling a more compact automatic transmission. Furthermore, since there is no need to relocate the counter drive gear rearward, the length of the counter shaft can be reduced, thereby enabling still greater compactness.

摘要翻译： 在自动变速器中，不能接合用于反向驱动的小容量第二离合器安装在反向传动齿轮的前方，并且具有相对较大容量的其它接合元件，即第一和第三离合器以及第一至第三制动器， 设置在相对驱动齿轮的后方，使得在对位驱动齿轮和第二离合器之间形成轴向延伸的空间，该空间用于容纳驻车档。 这种接合元件的布置允许相对轴放置得更靠近输入轴，而驻车齿轮不会干扰第二离合器，从而能够实现更紧凑的自动变速器。 此外，由于不需要向后移动对位驱动齿轮，所以可以减小副轴的长度，从而能够实现更大的紧凑性。
