Abstract: A linkage assembly couples a plunger of a brake valve to a manually operated brake input member. The linkage assembly includes a pushrod and a resilient member. The pushrod has an end member which is engagable with the plunger.The resilient member is attached to the pushrod end member. The resilient member has an end which is engagable with the plunger when the pushrod end member is spaced apart from the plunger. The resilient member deforms to allow the pushrod end member to directly engage the plunger when the pushrod end member is moved towards the plunger. One of the end and resilient members surrounds a portion of the other of the end and resilient members. The resilient member may be a sleeve which surrounds an end portion of the pushrod. Or, the resilient member may be surrounded by a hollow end portion of the pushrod.

Abstract translation: 联动组件将制动阀的柱塞连接到手动操作的制动器输入构件。 连杆组件包括推杆和弹性构件。 推杆具有可与柱塞接合的端部构件。 弹性构件附接到推杆端构件。 当推杆端构件与柱塞间隔开时，弹性构件具有可与柱塞接合的端部。 当推杆端构件朝向柱塞移动时，弹性构件变形以允许推杆端构件直接接合柱塞。 端部和弹性构件中的一个围绕端部和弹性构件中的另一个的一部分。 弹性构件可以是围绕推杆的端部的套筒。 或者，弹性构件可以被推杆的中空端部包围。
