Abstract: A track pin may comprise a body that includes a generally cylindrical configuration defining an axis of rotation, a circumferential direction and a radial direction, the body defining a first end, a second end and a peripheral surface extending from the first end to the second end. The peripheral surface may include a first lobed portion spaced axially away from the first end and the second end and including a series of convex arcuate segments and concave arcuate segments joined to each other tangentially, forming an undulating surface.

Abstract: A torque converter includes a housing, and an impeller shell disposed within the housing. The impeller shell has a back wall, and a plurality of fins radially arranged and extending outwardly from the back wall. The torque converter further includes a backing hub rigidly coupled to the back wall of the impeller shell. The backing hub has a barrier element extending therefrom. A free end of the barrier element is disposed proximal to the housing to restrict a flow of fluid therebetween.

Abstract translation: 变矩器包括壳体和设置在壳体内的叶轮壳体。 叶轮壳体具有后壁和从后壁径向布置并向外延伸的多个翅片。 变矩器还包括刚性地联接到叶轮壳体的后壁的衬套毂。 背衬轮毂具有从其延伸的阻挡元件。 阻挡元件的自由端设置在壳体的近侧以限制其间的流体流动。
