Q:The peak slip coefficient corresponds to the wheel slip rate
We know that the number of direct factors moving forward is related to ground friction, and when the friction is too small and the drive force is large, the car will slip. There is a proportional relationship between them is the adhesion coefficient. The attachment coefficient of the road is greatly changed by the wheel structure, material, road surface shape, material and the nature of the road. The general dry and clean leveling cement, asphalt pavement (called good road) longitudinal peak adhesion coefficient is as high as 0.8 ~ 0.9, While the vertical peak of ice and snow surface adhesion coefficient as low as 0.1 to 0.2. The maximum value of the adhesion coefficient is the peak adhesion coefficient, and the adhesion coefficient when the car is locked is called the sliding adhesion coefficient. Usually the sliding adhesion coefficient is 15% ~ 20% less than the peak adhesion coefficient. The lateral adhesion coefficient is basically the same as the slip rate (the slip ratio is the proportion of the sliding component in the wheel movement, in order to obtain the best braking effect, To control its slip rate in the range of 15% to 20%) increase and monotonically decline, when the slip rate of 100% when the wheel is fully locked drag, the lateral slip coefficient is zero, said the wheel at this time completely lost Resistance to lateral force, if the lateral force on the wheel, can only cause the side slip, can not turn, then the car lost steering maneuverability, which is very dangerous.
Q:Can I reduce the braking time by wheel reversal to shorten the braking distance?
The principle can be, but not economic, performance is also worse, obviously a very cheap brake pads brake disc, you have to wear their own engine transmission
Q:2017 Hot Wheels?
Definitely, if the wheels have a red line around them (as the racing cars used to), they are redlines.The early years of Hot Wheels are known as the Redline Era as until 1977 the wheels had a red line etched around the tire rim, popular on muscle cars at the time." Hot Wheels from the 2000s are not valuable now, but who knows. I bet in the 1970s they didn't think they would be valuable in 30 years either. If you're serious about collecting, buy two, one to play, one to save! NOTE: In 1993 Hot Wheels issued replica versions of their redline series. They are currently about 5 dollars each, much less expensive than the old ones: amzn.to/lcQ1v1
Q:Why the driving force of the car is greater than the wheel adhesion will appear slip phenomenon
The wheel of the adhesion is the maximum friction between the wheel and the ground The driving force of the car actually the engine reaches the drive shaft torque through the wheel and the ground contact point into force, the wheel rotation force is large enough, not slip, then the ground Friction force reaction to the wheel, to promote the overall image of the car as before, the friction coefficient is not enough, it can only slip hot smoke this to the brake brake to consider a reason to reverse, think of bicycle brake slip
Q:How does the wheel drive the physical knowledge of the car?
First through the engine to produce a steady stream of force, and then through the gearbox inside a variety of gear ratio of the final conversion through the differential force to wear the wheel together
Q:What is the role of wheel sensors?
When the wheel speed signal is detected on a vehicle, the most commonly used sensor is an electromagnetic induction sensor. The general practice is to mount the sensor on a nonrotating part (such as a steering knuckle or shaft) of the wheel assembly and to rotate with the wheel Magnetic material made of ring gear relative. When the ring gear relative to the sensor rotation, due to changes in the magnetoresistance, the sensor excitation of the alternating voltage signal, the frequency of alternating voltage and wheel speed is proportional to the ECU using a special signal processing circuit to convert the sensor signal to the same Frequency of the square wave, and then by measuring the square wave frequency or cycle to calculate the wheel speed.
Q:What is wheeled interrogation?
Wheel war is even the wheel turn, uninterrupted.
Q:In the braking process, the wheel lock when the maximum deceleration of braking. right?
Brake braking force and the ground can provide the maximum value of the same adhesion, even if the brakes continue to increase the braking force, the ground can not provide the appropriate reaction to balance, this time is the wheel lock state, hold Dead state between the wheel and the ground is pure sliding friction, rather than completely locked in the rolling state of the friction is static friction, high school physical knowledge can be seen, sliding friction is less than the maximum critical static friction value.
Q:Wobbly steering wheel?
Wheel bearing usually make a wooing sound but not much in the way of wheel shake. Have the new wheels been balanced? I assume they have, but worth checking as this can make the wheel vibrate at lot at higher speeds and is inexpensive to have done. Other than that, it might be a CV joint or suspension component, maybe a ball joint or even potentially warped brake discs or sticking brake callipers.
Q:What are the reasons for the wheel deviation?
Impression as long as the car deviation, most of the drivers will think it is to do the four wheel positioning, it is not true, resulting in a lot of reasons for deviation, tire pressure will be partial deviation, tread pattern wear degree is not the same deviation , Hanging system design problems or suspension of injury, deformation, displacement, etc. will occur deviation, in short, lead to a lot of reasons for deviation, but the four-wheel positioning is like a headache by the same way the same reason, all the deviation In fact, the problem will be mainly concentrated in the tires and suspension. X0d tires: you can first check the factory given the rated tire pressure, the pressure is not the same as the four- Most of the domestic cars are set between 2.0 and 2.5 bar, the pressure value of the front and rear wheels are also different, if the tire pressure will inevitably lead to deviation; in order to better use the tire, every twenty thousand kilometers should be replaced tire Of the position, because the drive wheel wear degree will always be larger than the other wheels, different friction will directly lead to deviation.
