    • A variable length track link (20) suitable for use in a bogie track has two link members (22, 24) and a releasable clamping means (44, 46). Each link member (22, 24) comprises a link pin (12), for coupling to a bogie track plate (4), and a transverse member (26, 28) attached, at least in use, to the link pin (12). The transverse members (26, 28) have engagement portions (34) with an engagement surfaces (36). The engagement surfaces (36) of the link members (26, 28) are formed and arranged for locking interengagement with each other when clamped together by the clamping means (44, 46), so as to hold the link pins (12) parallel and spaced apart at a selected distance. The distance is variable according to operational requirements by releasing the clamping means (44, 46) and moving the engagement surfaces (36) relative to each other and refastening the clamping means (44, 46).
    • 适用于转向架轨道的可变长度轨道连杆(20)具有两个连杆构件(22,24)和可释放的夹紧装置(44,46)。 每个连杆构件(22,24)包括用于连接到转向架轨道板(4)的连杆销(12)和至少在使用中连接到连杆销(12)的横向构件(26,28) 。 横向构件(26,28)具有带接合表面(36)的接合部分(34)。 连杆构件(26,28)的啮合表面(36)被形成并布置成在由夹紧装置(44,46)夹紧在一起时彼此锁定以相互啮合,以便保持连杆销(12)平行并且 以选定的距离间隔开。 通过释放夹紧装置(44,46)并使接合表面(36)相对于彼此移动并重新夹紧夹紧装置(44,46),该距离根据操作要求而变化。
