The invention relates to a trackless electric or hybrid electric vehicle (1) having a current collector (4) for supplying traction energy from a two-pole electric overhead line installation (3). The current collector (4) is provided with a supporting frame (7) which can be erected, a fixed end (10) of the supporting frame (7) is supported on the vehicle frame (2) in an articulated mode, and a free end (12) of the supporting frame (7) is connected with a rocker arm support (14) in an articulated mode. For each contact pole, the rocker arm (16, 17) with the friction strip (18) is elastically supported on the rocker arm support (14) through at least one spring assembly (19, 19 '). According to the invention, the restoring force (F) of the spring arrangement (19, 19 ') has a continuous spring characteristic curve (KL) over the contraction path (S) thereof. The contraction path (S) of the spring arrangement (19, 19 ') has, in succession, a first spring path (S1), in which the restoring force (F) increases by a first spring constant (K1), a second spring path (S2), in which the restoring force (F) remains constant, and a third spring path (S3), in which the restoring force (F) remains constant by a second spring constant (K1). The restoring force (F) increases with a second spring constant (K2) that is greater than the first spring constant (K1). As a result, a high contact quality can be achieved even when the contact line height varies.

    本发明涉及一种无轨电驱动或混电驱动交通工具(1),其带有集电器(4)用于从两极的电架空线设施(3)供应牵引能量。集电器(4)具有可竖起的支撑架(7),支撑架通过固定端(10)铰接支撑在交通工具框架(2)上,并且其自由端(12)与摇臂支架(14)铰接。在此对于每个接触极,带有摩擦条(18)的摇臂(16、17)分别通过至少一个弹簧组件(19、19′)弹性支承在摇臂支架(14)上。根据本发明,弹簧组件(19、19′)的恢复力(F)在其收缩路径(S)上具有连续的弹簧特性曲线(KL)。在此,弹簧组件(19、19′)的收缩路径(S)相继具有第一弹簧行程(S1)、第二弹簧行程(S2)和第三弹簧行程(S3),在第一弹簧行程上,恢复力(F)以第一弹簧常数(K1)增加,在第二弹簧行程上,恢复力(F)保持恒定,在第三弹簧行程上,恢复力(F)以相较于第一弹簧常数(K1)更大的第二弹簧常数(K2)增加。由此可以在触线高度变化时也实现高的接触品质。
