Description

BACKGROUND OF THE PRESENT INVENTION

1. Field of Invention
The present invention relates to a braking assembly, and more particularly to a braking assembly for use in high-speed train braking, high-speed motor vehicle braking, aircraft landing braking, high-speed underground train braking, and high-speed motorcycle braking
2. Description of Related Arts
Conventional high-speed trains, high-speed underground trains, high-speed motor vehicles, racing cars, sports cars, high-speed aircrafts, high-speed motorcycles all have a common problem of having inadequate braking ability. There have been many fatal accidents the cause of which related to the inadequate braking ability of high-speed vehicles when the vehicles suddenly encountered barrier in front of them. Example incident (1): in Jul. 23, 2011 at 20:02, train D3115 operating in Zhejiang province of China was hit by a lighting storm and stopped on a railway track. At 20:30, the captain of another train D301 noticed train D3115 stopped on the railway track in front of his train and applied brake to try to bring his train into a complete stop. However, due to high inertia of train D301, the captain was unable to stop the train in time and hit on train D3115. The incident was a cataclysm and caused 39 deaths and 192 injuries. The relevant trains were severely damaged which caused substantial loss of money. This incidents reveals the high-speed rail system in China suffers from many fatal disadvantages and requires as many as 11 areas of substantial improvements (at the time China introduced high-speed rail, the relevant Chinese authority paid a sum of approximately seven billions Renminbi consulting fee, and spent another ten billion Renminbi to purchase nine core technologies relating to high-speed rail, one of them was braking technology). At the time the incident occurred, one of the core technological areas (i.e. the braking technology) was unable to allow the relevant train to stop in time so as to avoid the accident just described. Example incident (2): In Apr. 28, 2008, a train operating in Shandong province of China derailed from the track because of speeding. The captain of another train discovered this incident, and applied the brake at an attempt to stop the train. However, due to high inertia of train, the captain was unable to stop the train in time and hit on derailed train. The incident was also a cataclysm and caused 70 deaths and 200 injuries, including 5 foreigners. Both trains were severely damaged. Example incident (3): In Oct. 27, 2000, train K860 was unable to stop in time and derailed. Example incident (4): in May 7, 1998, train 3018 was unable to stop in time and hit another train. Example incident (5): in Sep. 27, 2011, an underground train operating in Shanghai underground system hit another underground after failing to stop in time. The incident caused 200 injuries. The Rail authority in China required an emergency braking distances A for various range of train speeds V. A=800 m for V<120 km/hr., A=1400 m for 120 km/hr.<V<160 km/hr., A=2000 m for 160 km/hr.<V<200 km/hr., A=2700 m for 200 km/hr.<V<250 km/hr., A=3700 km for 250 km/hr.<V<300 km/hr., and A=4800 km for 300 km/hr.<V<350 km/hr. Throughout world history, there have been many catastrophic events involving train accidents due to inadequate braking ability of the trains. In order to resolve this deep-seated and worldwide problem, the Chinese Academy of Railway Science, the CNR Corporation Limited of China, the CSR Corporation Limited of China, CSR Ziyang Locomotive Co. Ltd. of China all have employed many academics, scientists engineers to research on this topic. Furthermore, many renowned universities, such as Southwest Jiaotong University, Beijing Jiaotong University, East China Jiaotong University, and Shanghai Railway Institute have devolved much resources to perform research on this topic but have failed to develop any effective method or system for effectively braking high-speed trains and high-speed underground trains. As a result, there exist many fatal accidents involving high-speed trains, racing cars, sports cars, buses and high-speed motorcycles. These accidents have been caused by inadequate braking ability on the part of the relevant vehicles. Moreover, there were approximately 300 deaths due to car accidents during national day holidays in 2011. In addition, a Chinese tour in Thailand encountered brake failure when the bus was travelling downhill. The accident caused 20 deaths and several injuries. The remedies furnished by the Thai government is merely equivalent to approximately Renminbi two hundred thousand. In September 2011, nine racing cars moving at 300 km/hr. in a F1 racing track were involved in an accident which caused death and injuries to some of the world top racing drivers. The accident also caused severe damage to the racing cars involved. These losses are due to inadequate braking ability, impact resistance on the part of the racing cars. As a matter of fact, there exist more and more automobiles throughout the world. However, the increased number of automobiles all share a common disadvantage of inadequate braking ability and impact resistance (because of extended braking distance and ineffective braking mechanism). This problem has caused increased number of traffic accidents. In order to resolve this worldwide problem, a huge amount of resources has been devoted. For example, MERCEDES of Germany spent Euro 2.4 billion in 2009 to perform research on this topic. The total amount of research funding used worldwide exceeds hundred billions. Many internationally famous automakers such as MERCEDES, BMW, VOLKSWAGAN, PORSCHE, and AUDI of Germany, GMC, FORD, and CADILLAC of United States of America, CITROEN and PEUGEOT of France, FERRARI of Italy, TOYOTA, HONDA, MITSUBISHI of Japan, and ROLLS ROYCE of United Kingdom have all devoted a great deal of resources to improve braking ability and impact resistance of their cars. These efforts have all failed. The huge amount of resources have allowed car manufacturers to develop a wide range of safety accessories such as seat belts, air bags, ejection seats etc. While these safety accessories may be able to protect the drivers, they have limited use in terms of minimizing car damage and protecting passengers. Shortening the braking distance is the most effective and the most economical way to improve vehicles' safety. The same problem arises in passengers aircraft and military aircrafts. Inadequate landing capability has caused many accidents on various kinds of aircraft. Aircraft manufacturers and research institutes have employed many top scientists, engineers, technicians and have acquired a huge amount of research funding, yet they have failed to provide an effective solution to resolve the problem of inadequate landing capability or ability of passengers or military aircrafts. Almost all conventional braking devices focus on the rotating portion of the relevant vehicles (i.e. the wheels) and utilize friction between the wheel surfaces and the corresponding contact surfaces (i.e. ground surfaces, tracks, etc.) to reduce the speed of the corresponding vehicles. This braking mechanism has the disadvantages of small contact surface area, inadequate braking friction and ineffective braking performance.

SUMMARY OF THE PRESENT INVENTION

The present invention provides a quick braking assembly which is capable of providing effective braking for high-speed trains, high-speed underground trains, and other vehicles. In order to resolve the problem of inadequate braking ability for high-speed trains, high-speed underground trains, and other vehicles, my invention provides additional braking for the relevant vehicles by using the vehicles' existing electrical power, and air braking system. The explicit embodiments of the present invention are: providing a device for removing raindrops or ice from a locomotive of a train or underground train so as to ensure the braking ability thereof when the train is travelling in adverse weather. (1) the present invention provides a road braking device which comprises a plurality (typically 4 to 6) lifting devices providing on a bottom portion of each of a railroad car of a train, wherein each of the lifting devices comprises a braking device (a braking clamp) providing on a bottom portion of the corresponding lifting device, and a braking member (the braking member may be configured by a material having a high coefficient of friction which is extremely suitable for use on a railway track, such as scouring rubber, brake shoe or any other material developed by research and development). When the braking devices are mounted on the bottom portion of the railcar, one skilled in the art must also consider the curvature of the railway track so as to ensure proper engagement between the braking devices and the railway track. This also ensures proper horizontal clamping pressure (for ensuring that the braking clamp properly clamps the railway track) and proper vertical clamping pressure (for ensuring that the braking clamp is kept to contact the railway track) may be exerted by the braking device for maximum safety and stability. A central control switch for all the braking devices are provided in the train operator's workplace. When emergency exists, the train operator may activate the train's existing brake system and the braking devices of the present invention through the central control switch, so as to allow each of the braking devices (braking clamps) to securely clamp on the relevant position of the railway track, and to allow the braking member to physically contact the railway track so as to develop a huge frictional force (braking force) between the railway track and the corresponding braking member for rapidly bringing the train to completely stop so as to prevent occurrence of accident. (2) the present invention further provides a plurality of air braking devices mounting on a predetermined position of each of the railroad cars. The air braking devices are provided on the last railroad car of the train and on two sides of each of the railroad cars. Each of the air braking devices is retractably and spacedly provided on the corresponding position of the corresponding railroad car. Each of the air braking device comprises an air resistance panel which is preferably red in color. Each of the air resistance panel is imprinted a predetermined characters, such as “STOP” for providing warning to any other incoming trains. The exact positioning and dimension of the air resistance panel must be determined by reference to the safety distance from two sides of the train. Therefore, the air braking devices (the air resistance panels) are provided on the last railroad car of the train and at two sides of each of the railroad cars. Moreover, the air braking devices are controlled by a main controller provided in the train operator's workplace. When emergency exists, the train operator may activate the train's existing brake system and the air braking devices of the present invention through the main controller, so as to allow each of the air resistance panels (red in color) to extend from the last railroad car and from two sides of each of the railroad car so as to develop huge air resistance for rapidly bringing the train to completely stop so as to prevent occurrence of accident. (3) the present invention further provides a plurality nozzle braking devices mounting on a bottom portion of each of the railroad cars (preferably at a position in the vicinity of each wheel assembly of the railroad car). Each of the nozzle baking devices comprises a nozzle having a flat nozzle head, wherein each of the nozzle braking devices is arranged to store a predetermined amount of braking agent. Preferably, there exist four nozzle braking devices provided around each wheel assembly. Two of the nozzle braking devices are arranged to eject the braking agent in frontal direction with respect to the wheel assembly, while another two of the nozzle braking devices are arranged to eject braking agent at rear direction with respect to the wheel assembly. The braking agent may be configured from a material which has very good and rapid adhesive performance (rapid adhesion) so as to increase the friction between the wheel assembly and the railway track. Examples of the braking agent may be A.B. adhesives, polyurethane, resin, epoxy, asphalt and other strong adhesives or materials developed by research and development in this area. The nozzle braking devices are centrally controlled by a main nozzle switch provided in the train operator's workplace. When emergency exists, the train operator may activate the train's existing brake system and the nozzle braking devices of the present invention through the main nozzle switch, so as to allow each of the nozzles to eject a predetermined amount of braking agent (rapid adhesives) to the railway track so as to increase the friction between the wheel assembly and the railway track for rapidly bringing the train to completely stop so as to prevent occurrence of accident.
The present invention also provides a quick braking assembly which is capable of providing effective braking for high-speed cars, buses, racing cars, sport cars, and other similar vehicles. In order to resolve the problem of inadequate braking ability for high-speed cars, buses, racing cars, sport cars, and other similar vehicles, my invention provides additional braking for the relevant vehicles based on the vehicles' existing braking system. The explicit embodiments of the present invention are: (1) the present invention provides a road braking device comprising a plurality of lifting devices providing on a bottom portion of the corresponding high-speed car, bus, racing car, sport car, or other similar vehicle, wherein each of the lifting devices comprises a braking member (the braking member may be configured by a material having a high coefficient of friction such as scouring rubber). Each of the braking members has a contact surface having a zigzag cross section for further increasing the friction between the braking member and a road surface when the braking members is in contact with the road surface. A central control switch for all the lifting devices is provided on the vehicle's dashboard. Each of the lifting devices is arranged to drive the braking member to optimally bias against the road surface. When emergency exists, the vehicle's driver may activate the vehicle's existing brake system by stepping on a brake's pedal and the braking devices of the present invention through the central control switch, so as to allow each of the lifting devices to drive the corresponding contact surface of the braking member to come into contact with the road surface so as to develop a huge frictional force (braking force) between the contact surface and the road surface for rapidly bringing the vehicle to completely stop so as to prevent occurrence of accident. (2) The present invention further provides a plurality of air braking devices retractably mounting on a predetermined position on a high-speed car, a bus, a racing car, a sport car, or on a similar vehicle. The air braking devices are provided on a rear portion and on two sides of the vehicle respectively. Each of the air braking device comprises an air resistance panel which is preferably red in color. Each of the air resistance panel is imprinted predetermined fluorescent characters, such as “STOP” for providing warning to any other incoming vehicles. The air braking devices are controlled by a main controller provided on the dashboard. When emergency exists, the driver may activate the vehicle's existing brake system and the air braking devices of the present invention through the main controller, so as to allow each of the air resistance panels (red in color) to extend from the vehicle so as to develop huge air resistance for rapidly bringing the vehicle to completely stop so as to prevent occurrence of accident. The characters imprinted on the air resistance panels are imprinted by fluorescent material and provide warning to incoming traffic even when the emergency occurs in a dark environment. Thus, the air braking devices may also prevent multiple vehicle collision.
