The amount of friction is designed to be some degree less than the return spring, so that when the pedal is released, it returns to the closed position.
设计时要确保总摩擦力小于折回弹簧的弹力，这样当松开踏板时，弹簧才会弹回，油门才会闭合。
But the friction (hysteresis) makes it easier to maintain a steady throttle setting, and relieves strain from pushing against the spring continuously.
但摩擦力(滞后作用)可以保证更平稳地完成油门设定，并缓解在持续挤压弹簧过程中产生的张力。
This always applies both for conservative forces, like gravitational and spring forces, but it also holds for nonconservative forces such as friction.
适用于保守力，像重力和弹力，对非保守力同样，适用，如摩擦力。
The friction force in the clutch works just like the blocks in the frication section of brake, except that the spring presses on the clutch plate instead of weight pressing the block into the ground.
离合器的摩擦力和制动器的摩擦力起一样的作用，不同的是压在地面上的重压力变成了离合器中弹簧压在离合器盘上的压力。
As the driver lets loose the clutch pedal, spring pressure increase on the clutch parts. Friction between the parts also increases.
一旦驾驶员松开离合器踏板，弹簧力就迅速作用在离合器上，摩擦力就随之增加。
The amount of force the clutch can hold depends on the friction between the clutch plate and they flywheel, and how much force the spring puts on the pressure plate.
离合器能传递的力的大小取决于离合器盘和飞轮之间的摩擦系数，以及弹簧对压盘的压紧力的大小。
There is no spring pressure on the clutch assembly parts. So there is no friction between the driving members and driven members.
离合器主动件、从动件上没有弹簧作用力，因此主动件和从动件之间也没有摩擦力。
With the aid of a spring scale (see above) the approximative coefficient of friction between a belt and a specific surface can easy be detected.
随着弹簧规模的援助(见上文)近似一条皮带和一个特定的表面之间的摩擦系数，可以很容易被发现。
Because the inner space of a hollow track is small, a driving wheel is arranged outside the hollow track in the prior art, and a dolly is driven to move by friction force generated by spring force.
由于空腹轨道内空间小，驱动轮安装在空腹轨道外部，靠弹簧力产生的摩擦力带动小车运行。
Several control handle configurations are available including spring return to center position, and friction hold which keeps the handle at any position desired.
可以提供几种手控配置，包括中心位置的弹力恢复以及保持手柄在某一特定位置所需的摩擦力。
The plate springs of the spring-loaded clutch press the friction discs together.
弹簧离合器的板簧将摩擦片压紧在一起。
In order to strengthen the brake action, a spring-acting friction-brake is designed.
为了加强制动作用，设计了一种加装反馈弹簧的织机制动机构。
A horizontal smoke pipe adopts a spring suspender and a central roller support, and the friction resistance generated by the thermal expansion the pipe when moving is reduced.
水平烟管采用弹簧吊、中心滚动支座，可减少管道热膨胀移动时的摩擦阻力；
