摘要： An automatic park lock for an off road or recreational utility vehicle includes a shift interlock solenoid with a spring biased plunger engaging and locking an operator shift lever in the park position. A cam surface on the operator shift lever slopes between a first end and a second end, and has a groove to lock the plunger to the park position. A controller energizes the shift interlock solenoid to retract the plunger when a plurality of operating parameters are satisfied.

摘要： A continuously variable transmission belt guide is mounted next to a driven clutch assembly and in close proximity with the CVT belt at the CVT's lowest drive ratio. The CVT belt connects between a pair of moveable sheaves of the drive and driven clutch assemblies to provide a variable CVT drive ratio between a lowest drive ratio and a highest drive ratio. When contacting the CVT belt, the CVT belt guide prevents a ripple or wave from appearing in the un-tensioned side of the belt, prevents the CVT belt from losing contact with the driven clutch, and prevents undesirable vehicle performance at the lowest drive ratio.
摘要翻译：无级变速传动皮带引导件安装在从动离合器组件的旁边，并以CVT的最低传动比与CVT皮带紧密相邻。 CVT皮带连接在驱动和从动离合器组件的一对可移动滑轮之间，以提供最低驱动比和最高驱动比之间的可变CVT驱动比。当CVT皮带接触时，CVT皮带导向器防止皮带未张紧的波纹或波浪出现，防止CVT皮带与被动离合器接触，并防止在最低传动比下出现不良车辆性能。
