制动阀

In this paper, simulated the air flow by use the fluid flow theoretics, based on the configuration and function of F8 distribution valve, established the air brake system model with F8 distribution valve.

本文采用气体流动理论模拟制动系统内空气的流动，并基于F8阀结构和功能建立了带有F8阀的列车制动系统物理模型。

This valve is used to control the emergency braking and parking braking and to examine the ability to park in a slope at the function of parking braking .

此阀用于控制具有弹簧制动室的主车及挂车的应急制动和驻车制动，并用来仅在停车制动的作用下检查汽车的停坡能力。

This valve is used to control the emergency brakeing and parking braking and to examine the ability to park in a slope at the function of parking braking .

此阀用于控制具有弹簧制动室的主车及挂车的应急制动和驻车制动，并用来仅在停车制动的作用下检查汽车的停坡能力。

It's necessary regulate the pressure between input and output of the valve, it can reduce the pressure on the front axle, and prevent form front whee lock during partial applications of brake, there by improving braking - performance.

用来调节输入和输出压力的比值使在较低的制动减速度时，减少前轴的制动气压，避免前轮制动时抱死，从而改善整车的制动性能，同时也起快放阀的作用。

It intergrates researching, manufacturing and selling together and specialize in producing spare parts of various types of cars,such as air brake parts, clutch booster, spring brake chamber, brake valve, relay valve and so on.It is one of the most important manufacturer of brake parts at home.

它集研发、制造、销售于一体，专业制造各种车型的气制动元件、离合器助力器、弹簧制动缸、手控阀、刹车总泵、继动阀等系列产品，是目前国内汽车制动元件的重要生产基地之一。

When the hydraulic pressure power supply stops or controls the solenoid valve opens, in driving pliers' pressure oil pressure vanishing, the piston under the precompression brake block spring's function rapidly promotes, affects on the friction liner and presses to is applied the brake the body, simultaneously the driven pliers in the driving pliers and under connecting bolt's function, lead through the glide guide pillar's function rub the liner to press to are applied the brake the sleeve to become the brake.

当液压动力源停止或控制电磁阀打开时，主动钳内的压力油压力消失，活塞在预压的制动弹簧的作用下迅速推出，作用在摩擦衬垫上并压向被制动体，同时从动钳在主动钳和连接螺栓的作用下，通过滑动导柱的作用带动摩擦衬垫压向被制动体完成制动。

Used the simulation program to calculate abundant conditions, to simulate the brake capability and brake rule of F8 distribution valve which affected by various parameter, researched the main factor which affect the brake capability of F8 distribution valve, including the length of pipes, the elasticity of springs and the area and weight of pistons.

在此基础上，论文使用该仿真程序，进行了大量的仿真计算，对各种不同参数影响下F8阀的制动性能和制动规律进行了仿真分析，研究了影响F8阀制动性能的主要因素，主要包括连接管的长度、弹簧的弹力以及活塞的面积和重量等。

The product that is form a complete set of east wind commercial vehicle basically has assembly of gimbal cross axle, rain to blow implement bearing of car of assembly of assembly, a powerful person of apply the bra......

为东风商用车匹配的制品主要有万向节拾字轴总成、雨刮器总成、制动阀总成、吃重轿车轴承等。据晓，自1997年以来，万向钱潮已经接连着8年被东风轿车评为年度杰岀供给商。

That would be like trying to drive down the road of innovation with the parking brake on.

这样就好像我们行驶在创新的大路上而同时却打开着制动阀。

Its composition and work principle are explained. Three problems existing in fully hydraulic brake system, brake pedal rebound and sudden braking, no inching braking; sudden power failure during traveling; spool seizure in fluid feeding valve and brake pump blasting, are analyzed. Concrete improvement measures are suggested.

论述了全液压制动系统的组成及工作原理，就全液压制动系统容易出现的以下三种问题：制动踏板反弹及制动剧烈，无点刹；行走过程中突然失去动力；充液阀阀芯卡死、制动泵炸裂进行了分析，并提出了具体的改进方案。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
