Systems and methods providing variable spring stiffness for weight management in a rail vehicle
摘要：
Systems and methods provide variable spring stiffness for weight management in a vehicle. One system includes a plurality of springs and a plurality of spring retainers configured to adjust a number of inactive coils of the plurality of springs. Additionally, a motor is provided that is connected to the plurality of spring retainers and configured to actuate the spring retainers to adjust the number of inactive coils of the plurality of springs. Further, a controller is provided that is coupled to motor to control the motor to actuate the spring retainers to adjust the number of inactive coils of the plurality of springs.
摘要（中）：

系统和方法为车辆中的重量管理提供了可变的弹簧刚度。 一个系统包括多个弹簧和多个弹簧保持器，其构造成调节多个弹簧的多个不活动的线圈。 此外，提供一种电动机，其连接到多个弹簧保持器并且构造成致动弹簧保持器以调节多个弹簧的非活动线圈的数量。 此外，提供了一个控制器，其耦合到马达以控制马达来致动弹簧保持器以调节多个弹簧的非活动线圈的数量。
