Description

抱轮机构及带该抱轮机构的安全车 技术领域 种抱轮机构及带该抱轮机构的安全车。 S 、 背景技术
汽车安全分为主动安全和被动安全, 被动安全又称碰撞安全。 主动安 全涉及驾驶操控性, 而被动安全则更是在汽车安全中起到主要作用。 汽车 被动安全技术主要分为两大类: 车身结构: 緩冲与吸能; 车内乘员保护: 安全带、 安全气嚢、 安全转向系统、 安全座椅等; 而车身结构技术在緩冲 与吸收撞击冲击力中起主要作用。 根据欧美对各种撞车事故的统计表明, 前撞最多, 尾撞次之, 侧撞再次之。 故而纵向的前后撞击在事故中最为多 见( > 60 % - 70 % )。 以最普遍的三厢轿车为例, 现代汽车车身结构的安全 设计特点是: 中间车身即乘员抢较硬, 车身壳体刚度尽可能最大, 而前、 后车身即发动机枪、 行李枪较软, 刚度较小, 有一定韧性; 当受到撞击 时, 通过前、 后车身的压缩变形, 来尽可能地吸收撞击的冲击能量, 以减 低对乘员舱的撞击破坏。 但这种仅靠汽车前、 后车身的压溃变形即毁车的 形式来緩冲吸能的能量极为有限, 如: 以全世界最严格测试标准著称的欧 洲 Euro- NCAP, 其新车正面碰撞 ( 40 % ODB )测试中获得最高 5星标准的最 大测试时速不超过 64km/h, 美、 日等发达国家与此类同, 故其安全效果仅 限于低中速碰撞。 随着高速公路的快速发展, 汽车行驶速度的大大增 加, 汽车碰撞时速亦大幅提高, 现有车身结构对较强的撞击力, 极易发生 压溃损毁。 因此现有技术的局限已日益凸显且无法根本性解决。 当今全世 界每年发生的大量 "车毁人亡" 汽车碰撞事故事例, 已充分说明了这一点。 因此, 针对现有汽车车身结构的缺陷, 必须研发新的安全车身结构来满足 现代行车安全。 发明内容
本发明的目的在于提供一种抱轮机构, 当发生碰撞时, 通过抱轮机构 緩沖、 吸收、 减低猛烈撞击力的同时, 将前或后纵向的水平沖击力转为相 向对压与垂直向下的力, 从车轮的前、 后、 上三方向同时抱压车轮, 利用 车轮充气轮胎强大的承重抗压性能, 最后将撞击力减力后传递到地面, 从 而保护车身结构不受撞击力而压溃损毁。
本发明的另一个目的在于提供一种带该抱轮机构的安全车, 通过抱轮 机构緩冲、 吸收、 减低猛烈的碰撞力的同时, 从车轮的前、 后、 上三方向 同时抱压车轮, 最后将撞击力减力后传递到地面, 可防止汽车损毁, 从而 最终保障车内驾乘人员安全。
