Description

液压油泵无磨损刹车系统 本发明是一种利用液压油泵的无磨损刹车系统, 它是一个把液压油泵装到汽车、火车刹车 系统的无磨损、 免维护的高效刹车系统, 目前常规的液压油泵都是给其它部件提供动能, 但 我们这套系统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。 本刹车系统可根据车辆型 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。 系统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系统, 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。  Hydraulic oil pump wear-free brake system The present invention is a wear-free brake system using a hydraulic oil pump, which is a wear-free, maintenance-free and efficient brake system for loading a hydraulic oil pump into a brake system of a car or a train. Currently, conventional hydraulic oil pumps are used. It is to provide kinetic energy to other components, but our system is to make the hydraulic oil pump not used as the dynamic energy, but to consume the kinetic energy brought by the inertia of the vehicle. It is especially for the large and medium-sized cars or trains existing in the existing brake technology. Defects were designed to invent. The brake system can design standard brake devices of different specifications according to different vehicle models and load capacities. As long as the device is installed on the car and the original brake device is replaced by the device on the train, As far as possible, the car is guaranteed to be safe when it is downhill, and for vehicles that need frequent braking, we can avoid brake failure caused by the redness of the brake drum or disk. When the oil pump valve is completely closed in the system, the oil resistance in the oil pump is converted into mechanical energy, and the tire or the train wheel is prevented from rotating by the gearbox, the transmission shaft, the rear axle, the axle shaft or the train axle, so that the vehicle is quickly stopped, and at the same time It also greatly reduces the wear and tear of the original brake drum and other parts, especially on the train, it can completely get rid of the existing brake system, to achieve the true sense of wear-free brakes, and maintenance-free, greatly reducing the country The cost of maintenance on the brakes of the train.
背景技术 Background technique
目前常用的刹车系统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。 这两种刹车系统在平路上还适用, 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系统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 火车刹车系统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。  At present, the commonly used brake systems include pneumatic brakes and oil brakes. Generally, the car uses oil brakes, and the trolleys and trains use pneumatic brakes. These two brake systems are also suitable for use on flat roads. However, in mountainous areas and long slopes, the brake drum or disc will heat up and become red. The brake drum or disc will lose its original strength or size in the red state, and the brakes will fail. , causing the vehicle to stop, and serious damage to the car. There are several existing solutions: 1 is exhaust brake, which is very common on large trucks, but the effect is not ideal; 2 is water, which is also a common means of large trucks, but often leads to drums or out of round 3 is electromagnetic eddy current brake, which is very common in high-end buses, the effect is ok, but not applicable on trucks; 4 is the addition of an auxiliary mechanical brake disc on the drive shaft, in addition to electromagnetic eddy current brakes, these The method can not fundamentally solve the safety hazard caused by the long slope, and all the existing brake systems rely on the brake drum or the disc to stop the vehicle, and the wear of the parts will be more serious. The existing train brake system uses the cast iron brake block by gas to squeeze the train wheel or the train brake disc to stop the train. This type of brake is very expensive in annual maintenance.
发明内容 Summary of the invention
本发明是一种利用液压油泵的无磨损刹车系统装置,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, 我们这套系统是无磨损的刹车系统。 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The invention relates to a wear-free brake system device using a hydraulic oil pump, which can well solve the problems brought by the automobile under the long slope and the need for frequent braking, and reduce the brake wear of the train and make the brakes of the train more. Reliable, there is no problem with brake heating, and maintenance costs are greatly reduced. We put a high-strength, high-precision high-pressure hydraulic pump on the gearbox of the car or the rear axle of the vehicle (also called the rear pocket), or on the axle of the train, through the gearbox, the drive shaft, the rear axle, and the axle (or the train axle) is connected to the tire (or train wheel). When the vehicle is driving, it will drive the hydraulic oil pump to rotate. We only need to install the oil pump's oil outlet - an ultra-high pressure pneumatic hydraulic valve to control the oil pump output. The size, so as to achieve the purpose of controlling the speed of the car. Of course, this method will also have a certain energy conversion. When controlling the small oil output, the oil temperature will rise. At this time, we need to install a hydraulic oil radiator to keep the oil constant, and ensure the mechanical parts. Normal operation. Our system is a wear-free brake system compared to the wear of brakes and other components such as brake drums. When the oil pump valve is completely closed, the oil resistance in the oil pump is converted into mechanical energy, through the gearbox, drive shaft, rear axle, and half shaft (or fire replacement page (Article 26) Wheel axle) to prevent the tire (or train wheel) from rotating, allowing the vehicle to quickly stop. Usually the design of hydraulic oil pumps is
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系统中, 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。 The small power of S produces the maximum oil output and the highest oil pressure as much as possible, so that the output power and the power consumption are as equal as possible. In the wear-free brake system of our hydraulic oil pump, the design of the hydraulic oil pump is contrary to the above theory. We need to consume its maximum power with the smallest possible oil output and minimum pressure.

具体实施方式 detailed description
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系统中, 低气压推动特高压气动液压油阀③, 刹车系统会全部 ^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 损刹车系统的效率稳定。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。  We put the high-performance hydraulic oil pump 2 on the vehicle gearbox 1 or on the rear axle, or the train axle@, at the oil outlet 6 of the oil pump (the oil pump and the oil valve are integrated on the train, this structure has very good pressure resistance). Good) Connect a high-precision UHV pneumatic hydraulic valve 3 to control the amount of oil pumping. In order to better operate this UHV pneumatic hydraulic valve 3, we should use UHV pneumatic hydraulically started synchronously with the vehicle pedal. Oil raft 3, a high and low pressure separator 4 is installed at the front end of the valve, but this high and low pressure separator is not required to be installed on the train, and it can be directly docked. When the driver gently steps on the brake plate, the gas enters the high and low pressure separator 4 through the high pressure air inlet 10 and becomes a low pressure gas, which is used to push the UHV pneumatic hydraulic oil valve 3, which can slow down or slow down the vehicle, when there is an emergency In the case, the driver steps down the pedal, the high and low air pressure separator 4 will send a large amount of gas to the original brake system of the whole vehicle, and the low pressure pushes the UHV pneumatic hydraulic oil valve 3, and the brake system will be fully moved. Of course, the temperature of the oil coming out of the UHV pneumatic hydraulic valve 3 will become higher. At this time, the oil from the UHV pneumatic hydraulic valve 3 must be sent to the hydraulic oil radiator 5 through the low pressure hydraulic oil pipe (Q) for cooling. At the constant temperature of the oil, the hydraulic oil for cooling Ji can be injected into the oil port of the oil pump through the low-pressure hydraulic oil pipe (Q), so that the hydraulic oil can be stably recycled to ensure the stability of the wear-free brake system. However, the brake device on the train can dock the original brake air pipe with the high-pressure air inlet 10 and use it directly.
