    • A welding unit (1) for welding two rails (3) of a track has two rail clamping units (2) that can be moved along unit guides (4) by compression cylinders (5) in the longitudinal direction of the rails, wherein each of said rail clamping units (2) is provided with clamping jaws (7) that can each be displaced in pairs in a pressure plane, each having a contact area (6) provided for contacting a rail web (30). The clamping jaws (7) are each configured as pivoting clamping levers (10) that can be pivoted around a lever pivot axis (8) in the pressure plane. The contact area (6) provided for contacting the rail web (30) is arranged on a first lever end (11) spaced apart from the lever pivot axis (8). Each of the two contact areas (6) of each rail clamping unit (2) is positioned closer to the opposite rail clamping unit (2) than the two lever pivot axes (8).
    • 一种用于焊接轨道的两个轨道(3)的焊接单元(1)具有两个轨道夹紧单元(2),所述两个轨道夹紧单元能够沿着轨道的纵向方向通过压缩缸(5)沿着单元引导件(4)移动,其中每个 所述导轨夹紧单元(2)设置有夹爪(7),所述夹爪能够在压力平面中成对地移位,每个夹爪具有用于接触导轨(30)的接触区域(6)。 夹爪(7)分别构造为枢转的夹紧杆(10),所述夹紧杆能够在压力平面中围绕杆枢转轴线(8)枢转。 设置用于接触轨道腹板(30)的接触区域(6)布置在与杠杆枢转轴线(8)间隔开的第一杠杆端部(11)上。 每个轨道夹紧单元(2)的两个接触区域(6)中的每一个都比两个杠杆枢转轴线(8)更靠近相对的轨道夹紧单元(2)定位。
