    • A shifter is provided for use with an automatic transmission on an automobile to enable the transmission to be shifted in a conventional mode and to enable the transmission to be upshifted quickly in a racing mode upon rapid sequential displacement of a master shift lever. The shifter comprises a stationary frame to which is pivotally connected a slave lever having one end connected to a shift arm on the transmission and having another end releasably connected to the master lever through a selector pin carried on the master lever. The slave lever is provided with a series of stepped surfaces which are selectively engaged by the selector pin to index the slave lever in one direction for upshifting the transmission when the master lever is pivoted sequentially against a stop. There is provided means to arrest pivotal motion of the slave lever at the completion of an upshift to prevent inertia forces on the slave lever from causing it to shift the transmission inadvertently. In each embodiment, there is provided means to bias the selector pin downwardly into engagement with the stepped surfaces for causing the pin to descend the surfaces as upshifting proceeds. In certain of the embodiments, there is provided means to bias the master lever into a home position at the completion of an upshift cycle.
    • 提供了一种与汽车上的自动变速器一起使用的换档器,以使得变速器能够以常规方式移动,并且能够在主变速杆快速顺序移位时使得变速器以赛车模式快速升档。 换档器包括固定框架,枢转地连接有从动杆,其一端连接到变速器上的换档臂,并且另一端通过承载在主杆上的选择杆可释放地连接到主杆。 从动杆设置有一系列台阶表面,当主控制杆相对于止动件枢转时,选择器销选择性地接合以便在一个方向上引导从动杆升档变速器。 提供了在升档完成时停止副杆的枢转运动的装置,以防止从动杆上的惯性力使其无意中移动变速器。 在每个实施例中,提供了用于将选择器销向下偏压以与台阶表面接合的装置,用于当升档进行时使销下降。 在某些实施例中,提供了在升档循环完成时将主杠杆偏置到原始位置的装置。
