Description

液压油泵无磨损刹车*** 本发明是一种利用液压油泵的无磨损刹车***， 它是一个把液压油泵装到汽车、火车刹车 ***的无磨损、 免维护的高效刹车***， 目前常规的液压油泵都是给其它部件提供动能， 但 我们这套***是让液压油泵不用作动能源， 而是用来消耗车辆惯性带来的动能， 是特别针对 大中型汽车或火车在现有刹车技术上所存在的缺陷来设计发明的。 本刹车***可根据车辆型 号的不同、载重量的大小设计出不同规格型号的标准刹车装置， 只要在汽车上加装这套装置、 在火车上用这套装置替换原有的刹车装置， 就能尽最大可能地让汽车在下长坡时保证汽车安 全， 而且对于需要频繁刹车的车辆， 我们可以避免因刹车鼓或盘发红发热导致的刹车失灵。 ***中当油泵阀门彻底关闭时， 油泵内油阻就会转化为机械能， 通过变速箱、 传动轴、 后桥、 半轴或火车轮轴来阻止轮胎或火车轮转动， 从而使车辆快速停下， 同时也很大程度 t减少了 原有刹车鼓等机件的磨损， 特别是在火车上， 它能完全摆脱现有的刹车***， 做到真正意义 上的无磨损刹车， 而且免维护， 大大降低国家在火车刹车维护上的费用。
背景技术
目前常用的刹车***有气动刹车和油动刹车， 一般小车用油动刹车， 大车和火车用气动刹 车。 这两种刹车***在平路上还适用， 但在山区、 下长坡时都会导致刹车鼓或盘发热、 发红， 刹车鼓或盘在烧红状态下失去原有的强度或尺寸， 让刹车失灵， 导致车辆无法停下， 严重的 会造成车毁人亡。 现有的解决方法有几种： 1 是排气制动， 这在大货车上很常用， 但效果不 理想； 2是淋水， 这也是大货车常用的手段， 但常常导致炸鼓或失圆； 3是电磁涡流刹车， 这 在高档大客车上很常用， 效果还可以， 但在货车上不适用； 4 是有人在传动轴上加装一个附 属机械刹车盘， 除电磁涡流刹车外， 以上这些方法都无法从根本上解决下长坡带来的安全隐 患， 而且所有的现有刹车***都是只靠刹车鼓或盘使车辆停下， 机件磨损会比较严重。 现有 火车刹车***都是利用通过气体挤压铸铁刹车块， 进而挤压火车轮或火车刹车盘从而使火车 停下， 这种刹车方式在年维护费上是很高的。
发明内容
本发明是一种利用液压油泵的无磨损刹车***装置，它能很好的解决汽车在下长坡时和需 频繁刹车情况下带来的问题， 以及减少火车刹车机件磨损， 让火车的刹车更可靠、 不会存在 刹车发热的问题， 而且大大减少维护费用。 我们把一个高强度、 高精密度的高压液压油泵装 在汽车的变速箱或车辆后桥 （也称后牙包） 上， 或火车轮轴上， 通过变速箱齿轮、 传动轴、 后桥、 半轴 （或火车轮轴） 与轮胎 （或火车轮） 相连， 车辆在行驶时会带动液压油泵转动， 我们只需要在油泵的出油口装上- -个特高压气动液压油阀控制油泵出油量的大小， 从而达到 控制车速快慢的目的。 当然这种方式也会有一定的能量转换， 在控制很小的出油量时， 出来 的油温会上升， 这时我们就需要加装液压油散热器来保持油的恒温， 保证机件的正常运转。 相对现有刹车时刹车鼓等机件的磨损情况而言， 我们这套***是无磨损的刹车***。 当油泵 阀门彻底关闭时， 油泵内油阻就会转化为机械能， 通过变速箱、 传动轴、 后桥、 半轴 （或火 替换页 （细则第 26条) 车轮轴） 来阻止轮胎 （或火车轮） 转动， 从而使车辆快速停下。 通常液压油泵的设计都是由
S小的功率尽可能产生最大的出油量、最高的油压， 从而让产出功率和消耗功率尽可能相等， 可在我们液压油泵无磨损刹车***中， 液压油泵的设计与上述理论相反， 我们要用尽可能小 的出油量、 最小压力来消耗掉它最大的功率。
附图说明
附图 1为无磨损刹车***中液压油泵装在变速箱上的工作原理图，附图 2为无磨损刹车系 统中液压油泵装在车辆后桥上的工作原理图， 附图 3为液压油泵装在火车车轮轴上的工作原 理图。 下面结合附图进行进一步说明： 附图中①变速箱， ②液压油泵， ③特高压气动液压油 阀， ④高低气压分离器， ⑤液压油散热器， ⑥高压液压油出口， ⑦低压气出口， ⑧高压液压 油管， ⑨低压进气口， ⑩高压进气口， 低压液压油管， ©高压气出口， 与原刹车*** 连接气管， Θ油泵回油口， ©油阀出油口， @后桥， Θ半轴， ®轮胎， Θ传动轴， @ 轮轴， @传动齿轮箱
具体实施方式
我们把高性能的液压油泵②装在车辆变速箱①上或后桥 、或火车轮轴 @上， 在油泵的 出油口⑥ （火车上是油泵和油阀一体结构， 这种结构耐压性能很好） 连接一个高精密度特高 压气动液压油阀③以控制油泵出油量的大小， 为了更好地操作这个特高压气动液压油阀③， 我们应选用跟车辆踏板同步启动的特高压气动液压油闽③， 该阀门前端加装一个高低气压分 离器④， 但在火车上不 ^要加装这个高低气压分离器， 直接对接就行。 当司机轻踏刹车板时， 气体通过高压进气口⑩进入高低气压分离器④后变成低压气， 用于推动特高压气动液压油阀 ③， 可使车辆减速或缓慢停下， 当有紧急情况时， 司机一脚踏下踏板， 高低气压分离器④会 把大量的气送至全车的原刹车***中， 低气压推动特高压气动液压油阀③， 刹车***会全部 ^动。 当然， 从特高压气动液压油阀③出来的油温度会变高， 这时必须把特高压气动液压油 阀③出来的油通过低压液压油管 (Q)送入液压油散热器⑤进行冷却， 保证油的恒温状态， 冷却 Ji的液压油可通过低压液压油管 (Q)注入油泵的 ^油口， 让液压油稳定循环使用， 以保证无磨 损刹车***的效率稳定。不过火车上的刹车装置可把原有的刹车气管与高压气进气口⑩对接， 直接使用即可。
