Description

技术领域 Technical field
本发明涉及一种车辆行驶， 飞机着陆的紧急刹车装置。  The invention relates to an emergency braking device for a vehicle running and an airplane landing.
背景技术 Background technique
众所周知， 汽车已成为现代人们生活中不可缺少的交通运输工具， 给人们的生活水平提高和社会的进步起了很大的作用。 但在汽车带来 诸多好处的同时也为人们带来灾难， 这就是频繁发生的交通事故。 交 通事故发生的一个重要原因是， 车辆在急刹车后， 无法解决本身的惯 性， 而继续向前滑行， 滑行距离越远， 造成交通事故的可能性越大， 因而如何尽量缩短刹车距离， 特别是紧急制动距离很有必要。  As we all know, cars have become an indispensable means of transportation in modern people's lives, which has played a significant role in improving people's living standards and social progress. But while cars bring many benefits, they also bring disasters to people. This is a frequent traffic accident. An important reason for a traffic accident is that after the vehicle suddenly brakes, it cannot resolve its inertia and continues to taxi forward. The farther the taxiing distance is, the greater the possibility of a traffic accident, so how to shorten the braking distance as much as possible, especially Emergency braking distance is necessary.
为解决上述问题， 必须先了解影响刹车距离的因素。 设一辆车的 质量为 M(kg), 刹车距离为 L(m)， 附着系数为 φ， 则车速为 V(m/s)的 车辆紧急刹车， 从刹车至停车间的距离 L:  To solve the above problems, you must first understand the factors that affect the braking distance. Assuming that the mass of a car is M (kg), the braking distance is L (m), and the adhesion coefficient is φ, then the vehicle with a speed of V (m / s) brakes emergencyly. The distance from the brake to the parking space L:
则可用下式表示： Can be expressed by the following formula:
F · L = MV2 (1) 式中， F为摩擦力 （N) , F · L = MV 2 (1) where F is the friction force (N),
又因为：  also because:
F = (j>N = (J)Mg (2)  F = (j> N = (J) Mg (2)
式中， N为刹车时车辆作用于路面的正压力， g为重力加速度。 将 2式代入 1式， 得  Where N is the positive pressure of the vehicle on the road surface during braking, and g is the acceleration due to gravity. Substituting Type 2 into Type 1 gives
^ 2F 2φδ 1 ^ 2F 2φ δ 1
将 g = 9.8m/S2, 车速 V(km/h)代入 (3)式， 得： Substituting g = 9.8m / S 2 and vehicle speed V (km / h) into equation (3), we get:
V2 V 2
L = S5i (4) L = S5i ( 4 )
由 （4 ) 式中见， 刹车距离 L只与 ν、 φ有关， 而与 M无关。 所以， 在车速 V—定的情况下， φ越大， L越小， 而 φ是一个在一定范围内变 化的值， 如何使 φ保持最大， 现有的 ABS 防抱死刹车系统基本上满足 了这一要求， 使 L尽量保持在最小状态， 但因刹车距离过长而产生的 交通事故仍然频繁发生， 故设计新的紧急刹车装置尤为必要。 徐玉庆设计了 《一种汽车惯性阻尼装置》 （公告号 2269347 ) ， 它是在汽车底盘上设一托架， 托架通过弹性铰链、 连接支杵装总吸盘， 总吸盘上设有带单向阀的排气孔。 在紧急刹车时， 通过操纵机构使总 吸盘迅速着地滑行并变形， 总吸盘的空气由排气口排出， 滑行时铲口 将污物铲除， 保证总吸盘的边缘与地面较好地吸附， 增大汽车与地面 的接触面及阻力， 减少汽车急刹车后惯性滑行距离。 从其描述看， 他 是想利用吸盘的吸力， 增大汽车与地面的接触面及阻力紧急刹车。 但 其描述又为总吸盘着地后， 总吸盘内的空气由排气口排出， 既有气体 排出， 盘内的空气必大于或等于外部的气压， 因而不可能形成负压或 真空， 因而不可能有吸力。 另外从前面分析可见制动距离与接触面积 无关， 故其接触面积增大， 也增大不了阻力。 由上述分析看， 由总吸 盘对地面的吸力， 来减少滑行距离的构想不能成立。 As can be seen from the formula (4), the braking distance L is only related to ν and φ, and has nothing to do with M. Therefore, under the condition of constant vehicle speed V, the larger φ, the smaller L, and φ is a value that changes within a certain range. How to keep φ to the maximum, the existing ABS anti-lock braking system basically meets This requirement keeps L as small as possible, but it is caused by the long braking distance. Traffic accidents still occur frequently, so designing new emergency braking devices is particularly necessary. Xu Yuqing designed "An Automobile Inertial Damping Device" (Bulletin No. 2269347), which is provided with a bracket on the chassis of the car, and the bracket is connected to the support rod through a flexible hinge, and the total suction cup is equipped with a check valve. Exhaust vent. During emergency braking, the total suction cup is rapidly slid and deformed by the operating mechanism. The air of the total suction cup is exhausted from the exhaust port, and the shovel mouth is used to remove dirt during taxiing. The contact surface and resistance between the car and the ground reduce the coasting distance after the car brakes sharply. From its description, he wanted to use the suction of the suction cup to increase the contact surface of the car with the ground and the emergency braking. However, its description is that after the total suction cup is grounded, the air in the total suction cup is discharged through the exhaust port, and the existing gas is discharged. The air in the tray must be greater than or equal to the external air pressure, so it is impossible to form a negative pressure or a vacuum, so Suction. In addition, it can be seen from the previous analysis that the braking distance is not related to the contact area, so the contact area increases, and the resistance cannot be increased. From the above analysis, the idea of reducing the gliding distance by the suction of the total suction cup on the ground cannot be established.

参照附图， 盖体 10在静或动状态中始终处于与路面平行的位置。 支承杆 11的上部通过销 12与连接板 15相联， 连接板 15靠螺栓安装 于汽车后桥 2上。 支承杵 11内部装有弹簧， 弹簧起减震和调节高度的 作用。 支承杵 11下部通过销 9与伸缩拉杆 6相联， 伸缩拉杵另一端通 过销 3与连接板 15相联。  Referring to the drawings, the cover 10 is always in a position parallel to the road surface in a static or dynamic state. The upper part of the support rod 11 is connected to the connecting plate 15 through a pin 12, and the connecting plate 15 is mounted on the rear axle 2 of the car by bolts. The supporting pestle 11 is provided with a spring inside, and the spring plays a role of damping and adjusting height. The lower part of the supporting pestle 11 is connected to the telescopic pull rod 6 through a pin 9, and the other end of the telescopic pull pestle is connected to a connecting plate 15 through a pin 3.
盖体骨架 36为金属骨架， 中部开有孔 13, 软管 16连通孔 13与 真空泵 19的进气口。 摩擦体 33通过螺栓 34装在盖体下边。 摩擦体为 橡胶制品， 其与地面接触的表面有轮胎状花纹。 盖体四周用螺栓 30固 定弹性密封带 31、 密封團 32。  The cover body frame 36 is a metal frame, and a hole 13 is formed in the middle of the cover 13 to communicate with the hole 13 of the hose 16 and the air inlet of the vacuum pump 19. The friction body 33 is mounted below the cover body by a bolt 34. The friction body is a rubber product, and the surface in contact with the ground has a tire-like pattern. Around the cover, bolts 30 are used to fix the elastic sealing band 31 and the sealing group 32.
本发明的工作原理如下：  The working principle of the present invention is as follows:
行车途中， 刹车踏板 28位于虛线处， 开关 29断开， 电磁阀 22的 电磁线團 21无电， 电磁阀 22处于常位 I， 真空泵 19无电不工作， 盖 体 10在回位弹簧 5的作用下收起， 处于图中虚线位置。  During driving, the brake pedal 28 is located at the dotted line, the switch 29 is turned off, the solenoid 21 of the solenoid valve 22 is de-energized, the solenoid valve 22 is in the normal position I, the vacuum pump 19 is not operated without electricity, and the cover 10 is in the return spring 5 Under the effect of, put in the dotted line in the figure.
刹车时， 踩下刹车踏板 28至实线位， 开关 29接通， 电磁线團 21 得电并工作， 使电磁阀 22处于接通 II位， 空压机贮气筒 25中的压缩 空气经软管 24、 软管 20流入汽缸 7 内， 所产生的推力克服了回位弹 簧的拉力， 盖体 10迅速下移， 并带动伸缩拉杆 6展开。 盖体落至图中 实线位置后， 盖体下方的空腔与地面 14形成密封腔。  When braking, depress the brake pedal 28 to the solid line position, switch 29 is turned on, the solenoid 21 is energized and works, and the solenoid valve 22 is turned on in the II position. The compressed air in the air compressor air cylinder 25 is passed through the hose. 24. The hose 20 flows into the cylinder 7 and the generated thrust force overcomes the pulling force of the return spring, the cover body 10 moves down quickly and drives the telescopic pull rod 6 to expand. After the cover has fallen to the solid line position in the figure, the cavity below the cover and the ground 14 form a sealed cavity.
同时真空源也得电工作， 通过软管 16对密封腔抽真空， 使盖体 10 内外形成压差， 压力继续下压盖体， 使摩擦体与路面紧密接触， 增大 摩擦力与阻力， 达到制动之目的， 此压力贯穿于整个制动过程中。 真 空源可采用真空泵 19。  At the same time, the vacuum source must be powered to work, and the sealed cavity is evacuated through the hose 16 to make a pressure difference between the inside and outside of the cover body 10. The pressure continues to press the cover body to bring the friction body into close contact with the road surface, increasing friction and resistance to reach For braking purpose, this pressure runs through the entire braking process. The vacuum source can be a vacuum pump 19.
停车后， 松开刹车踏板 28回至虛线位， 开关 29断开， 真空泵 19、 电磁线團 21失电， 电磁阀 22回位 I处， 盖体 10密封腔内真空解除， 汽缸 7内的高压气体经电磁阀 22放出。 在回位弹簧 5的作用下， 空气 经密封带 31、 密封圈 32与路面 14间的空隙进入空腔 37内， 盖体 10 回至虚线位置， 并由回位弹簧 5保持住， 以备下次再用。 After stopping, release the brake pedal 28 to the dotted line position, switch 29 is turned off, the vacuum pump 19 and the electromagnetic coil 21 are de-energized, and the solenoid valve 22 is returned to position I. The vacuum in the sealed cavity of the lid 10 is released, and the The high-pressure gas is released through the solenoid valve 22. Under the action of the return spring 5, air enters the cavity 37 through the gap between the sealing band 31, the sealing ring 32 and the road surface 14, and the cover 10 Return to the dotted line position and hold it by the return spring 5 for future re-use.
图中其它标注分别为： 1汽车后轮、 4销、 8销、 17汽车大梁、 18 油水分离器及过滤器、 23弹簧、 35销座。  The other labels in the picture are: 1 car rear wheel, 4 pin, 8 pin, 17 car beam, 18 oil-water separator and filter, 23 spring, 35 pin seat.
由以上工作过程可看出， 本发明比原刹车装置多了通过摩擦体作 用于路面的大气压力， 并贯穿于整个过程中。 这样车辆对路面的压力 除 Mg外， 还多了 ΔΡΑ， 其中 ΔΡ为盖体在制动过程中的内外压力差， Α为盖体与路面间形成的密封面积， 此时（2 ) 式即变为：  It can be seen from the above working process that the present invention has more atmospheric pressure applied to the road surface through the friction body than the original braking device, and runs through the entire process. In this way, in addition to Mg, the pressure of the vehicle on the road surface is increased by ΔPA, where ΔP is the pressure difference between the inside and outside of the cover during braking, and Α is the sealing area formed between the cover and the road surface. At this time, the formula (2) changes. For:
F' = (|)Mg+APAg (5)  F '= (|) Mg + APAg (5)
将 5式代入 3式中  Substitute Formula 5 into Formula 3
V2 V 2
L' =  L '=
254φ ( 1 + ^ ) (6) 由 (6)式可见， 采用本发明， 只要真空泵在刹车过程中对盖体持续 抽真空， 就必然有 ΔΡ存在， 刹车距离就肯定要缩短。  254φ (1 + ^) (6) As can be seen from the formula (6), with the present invention, as long as the vacuum pump continues to evacuate the cover during braking, there must be ΔP, and the braking distance must be shortened.
综上所述， 由于本发明利用大气压力产生制动， 这与传统只利用 地心引力制动有了质的不同， 同时又增大了接触、 密封面积， 其制动 效果更佳。 此外盖体下的摩擦体可减少对路面的损害。 采用本发明， 可在现有车辆制动效果基础上， 缩短制动距离 20 % - 50 %， 为车辆安 全运行、 飞机安全着陆， 提供了一种安全可靠的紧急制动源。  In summary, the present invention uses atmospheric pressure to generate braking, which is different from the traditional use of gravity-only braking. At the same time, the contact and sealing area is increased, and the braking effect is better. In addition, the friction body under the cover can reduce the damage to the road surface. By adopting the present invention, the braking distance can be shortened by 20%-50% based on the existing vehicle braking effect, which provides a safe and reliable emergency braking source for the safe operation of the vehicle and the safe landing of the aircraft.
