迈凯伦F1赛车采用全新密封技术

来源：AMPTI

迈凯伦F1方程式车队已采用Greene Tweed的金属弹簧蓄能（MSE）密封圈，用于其限滑差速器离合器组的液压执行器。

Greene Tweed在2月11日的一份公告中表示，该密封系统用于夹紧差速器内部摩擦离合器的执行器中。该系统旨在优化扭矩分配，以实现最大的牵引力和弯道速度，而密封的完整性在该系统中至关重要，因为严重泄漏将导致"系统功能丧失，并迫使赛车退赛"。

Greene Tweed开发了两种带有C形轮廓和耐腐蚀金属弹簧的MSE密封组件，以提供"均匀的密封力"。该公司表示，这些密封圈采用Greene Tweed的Avalon 44聚四氟乙烯（PTFE）材料制造，设计用于在应用的极端条件下运行，包括高达150°C的温度、5至250巴的压力，以及接触腐蚀性流体。PTFE材料确保了"卓越的耐磨性、高强度和低摩擦，满足了关键任务行业的严苛要求"。该项目在系统获批使用前，会在比赛条件下的联合验证和测试。
