用于无螺丝地固定轨道车辆的轨道的系统和固定点
Abstract:
本发明提供一种用于无螺丝地固定轨道的系统和位于基底上的相应的固定点，该系统和固定点装配简单并且在恶劣的使用条件下以及具有最大负荷能力的同时仍确保最佳的可靠的固定。为此，这种系统包含由弹簧钢丝弯曲而成的弹性元件(4)和支撑肩(2)。弹性元件(4)由其一端出发，依次具有支承区段(4a)、曲线区段(4b)、与支承区段(4a)反向定向的压紧区段(4c)、朝支承区段(4a)的方向弯曲的曲线区段(4d)以及指向相对于支承区段(4a)的横向的锁定区段(4e)。在未装配弹性元件(4)时，从侧面观察，在压紧区段(4c)和锁定区段(4e)之间具有间距(a)。同时，支撑肩(2)包括用于将支撑肩(2)固定在基底(U)上的固定区段；由固定区段承载的载体区段(2a)；形成在载体区段(2a)上的、用于可围绕转动轴转动地支承支承区段(4a)的支承缺口(2f)；以及由载体区段(2a)承载的锁定头(2b)，如此在该锁定头上形成用于锁定区段(4e)的对向支承处(2i)，即在系统(1)完成装配时，锁定区段(4e)保持在相对于弹性元件(4)的支承区段(4a)的这样的位置中，在此位置中，弹性元件(4)被弹性地压紧在支撑肩(2)的支承缺口(2f)和对向支承处(2i)之间并且压紧区段(4c)弹性地作用在与其对应的轨底(F)的表面上。
Abstract(English):

A system for a screwless rail fastening includes a spring element and a supporting collar. The spring element has a bearing section, a curved section, a holding-down section, aligned in the opposite direction to the bearing section, a curved section curved in the direction of the bearing section, and a locking section aligned transversally to the bearing section. The supporting collar includes a fastening section for retaining the supporting collar on the foundation, a carrier section supported by the fastening section, a bearing recess formed on the carrier section for mounting of the bearing section, and a locking head supported by the carrier section on which a counter-bearing for the locking section is formed so that the locking section is retained in a position relative to the bearing section of the spring element.
