动力制动

When power is transmitted to the elevator shaft, it drives the splined center wheel and the planetary mechanism which consists of three planetary wheels forming 120 degrees with each other and the inner gears drives the drum to rotate, the hoisting band brake is combined with the hoisting disc, and the drum's left ring is combined with the braking band brake, then the elevator has three status: hoisting, braking, and lowering down.

当动力传至升降机轴后，轴带动与花键联接的中心轮，三个互成120度的行心轮及内齿圈组成的行星机构，使卷筒回转，提升抱闸与提升盘结合，卷筒左端外圈与制动抱闸结合，这样升降机具有提升、制动、下降三种工作状态。

This is due to a braking system that assures fast, gradual braking and also shorter stopping distances; ventilated front discs with a diameter of 330 millimetres with Brembo fixed aluminium callipers with four pistons (38 and 42 mm)- and an ABS system with four active sensors complete with an EBD electronic brakeforce distributor.

这是由于刹车系统，保证快速，并逐渐缩短刹车制动距离，通风的330与Brembo四活塞（38和42毫米）- ABS系统和固定铝制卡钳毫米直径的前制动盘4活跃传感器在开机片电子制动力分销商完成。

The full power hydraulic brake system has several advantages over traditional brake actuation systems.

Therefore, the in-depth research on the process of dynamic loads when braking ,the analysis about the causation and influence factor of the dynamic loads" emergence is necessary to the design of the circumgyrate machinery Aim at above problems, this text treats the portal crane"s boom system as a research object ,using finite element analysis and mechanism kinetics as theories foundation and analysis means ,utilizing ANSYS8.1 to research the dynamic effect of the crane boom under the circumstance of braking.

针对以上问题，本文以MQ4033门座起重机臂架系统为研究对象，以有限元和机械动力学为理论基础，运用ANSYS8.1对臂架系统在回转制动时的工况进行动力学分析，获得了臂架系统的模态特征以及在回转制动时的动力响应。

Followingly,among the existing brake control strategy, most don't consider the problem of battery anti-overcharging.So,a practical electric vehicle regenerative braking strategy that considering battery state of charge is proposed, and braking force distribution controller and regulator are designed respectively according to vehicle safety requirements and battery SOC constraint.

接着针对现有制动控制策略中，未考虑抑制电池过充的问题，提出了一种实用的考虑电池SOC约束的再生制动力分配策略，根据车辆前后轮制动力安全要求和电池SOC约束，分别设计了前后轮制动力分配控制器和制动力调节器。

The paper establishes stress-model about the roller bra ke tester and the flat brake tester, Moreover analyzes the model and compares their strongpoint and disadvantage t hrough simulating their actual work condition, At last educe their use range and their integrated use in brake force test.

建立了滚筒制动试验台和平板制动试验台受力分析模型，并通过模拟它们的实际工况来分析它们的受力模型，比较它们各自的优缺点，最后得出了它们的使用范围，以及在制动力检测时它们的结合使用。

The result indicates the wheels dont lock on every road surface, as shows the ability of avoiding the wheel locking. The values of slide ratio approach and revolve round the best slide ratio constantly, which indicates this method utilizes the character of pavement thoroughly, and the braking efficiency is excellent.

结果表明在各种路面车轮几乎没有抱死，显示了自寻优避免车轮抱死的能力；滑移率的值基本上一直接近并围绕最佳滑移率变化，说明该方法充分利用了路面性能，制动性能较好；制动力矩及制动力随着路面条件的变化自动做出相应调整，实现了路面自动识别功能。

To disengage the drivetrain, neutral was located by the parking/emergency brake lever, pulling the hand lever back engaged the brake while disengaging the multiple-disk clutch.

为了实现动力转向，空档位于手制动与紧急制动上，通过拉手刹的方式可以实现离合器的分离。

Everyone know that make to move the result biggestly is an occurrence before tire lock die moment, if can let the car of system motive has been keep at with the appearance of the tire friction balance, will acquire to make to move the result biggestly so.

大家都知道最大的制动效果是发生在轮胎锁死前的瞬间，如果能够让剎车制动力一直保持在与轮胎摩擦力平衡的状态，那么将获得最大的制动效果。

Service brake with self-lock function of the hydraulic closed circuit is applied simultaneously with the parking brake for reliability and prompt.

无动力停车制动系统，当发动机熄火时或液压系统故障时自动实现制动，也可用开关操作实现，安全可靠。6。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。

Galvanizes steel pallet is mainly export which suits standard packing of European Union, the North America. galvanizes steel pallet is suitable to heavy rack. Pallet surface can design plate type, corrugated and the gap form, satisfies the different requirements.

镀锌钢托盘多用于出口，替代木托盘，免薰蒸，符合欧盟、北美各国对出口货物包装材料的法令要求；喷涂钢托盘适用于重载上货架之用，托盘表面根据需要制作成平板状、波纹状及间隔形式，满足不同的使用要求。
