Q:What is the meaning of the four-wheel drive?

A form of a four-wheel drive vehicle drive system means that the driver can change the two-wheel drive or four-wheel drive mode by turning on or off the splitter according to the road conditions to achieve two-drive and four-wheel drive free conversion The way of driving. Time-sharing four-wheel drive usually only use the front wheel or rear wheel drive to drive, in the snow or gravel road can be switched to four-wheel drive to exercise, also known as the choice of four-wheel drive. This is also the most common drive mode for off-road vehicles or four-wheel drive SUVs.

Q:What is the flywheel in the auto parts?

Flywheel is used as the starting motor of the passive parts, the clutch of the active parts, divided into two, one is the mechanical clutch, one liquid adapter, which is used since the car. The friction surface of the flywheel is driven by the clutch plate of the clutch and transmits power to the gearbox when the vehicle travels. When the driver depresses the clutch pedal, the clutch plate leaves the flywheel so that the power transmission is interrupted and the gear is shifted. Leaving the pedal, clutch plate and flywheel contact, power will resume transmission.

Q:Car drive mode

The rear engine rear wheel drive was widely used in miniature cars because of its compact structure, neither a heavy drive shaft nor a complicated front wheel steering and drive structure. Its drawback is that the rear axle load is large, in terms of handling will have the opposite of FF overturning tendencies, that is, high-speed cornering stability is poor, easy to slip. There are already very few cars that still use RR layout. Porsche 911 is one, and it is easy to flick the handling characteristics is also out of the name.

Q:Whether the front or rear drive, when the car slips only one tire drive, while the other in the coaxial tires do not seem to drive? There is also a diesel forklift (forerunner) that is always a tire slip when pushing the goods to slip. The ground with a tire to leave a black mark. The other does not seem to move. Does that drive a wheel when the car is running in a normal way?

This is the car's differential at work. If the normal driving, the two wheels are rotating at the same time.

Q:Hello! You know where to sell auto parts is , you can tell me

Really do not know, you can APP such as " search", " map" direct search for your nearby "auto parts", not a second can help you find out. And then click to open, by address or phone, you naturally know. The

Q:What is the reason why the car drives the hub overheating

Bearing brake pads and so on

Q:Which wheel is driven by the car

The biggest advantage of the front wheel drive is that it can have a large interior space, the cab will not have a drive shaft through a large protrusion. Look at the Civic, you will find that this car can also have many cars can not match the back seat space, the reason is that there is a flat floor, at the same time, there is no post-differential, luggage space Will get increased.

Q:By theory, the driving force at the highest speed should be equal to the driving resistance, then the two lines should intersect, but the results of my simulation is not the case, which experts to confuse some

Is your driving force parameter measured from the engine output? I do not know how you got it. I estimate the error is due to the resistance of the transmission

Q:Now so many cars are front-wheel drive, why not rear-wheel drive, front-wheel drive and rear drive the pros and cons is where?

Not the main reason is the cost of the relationship, of course, there are security considerations. Snow and slippery drive a little more reliable (really just a little bit!)

Q:What is the structure of the car drive bridge?

The drive axle assembly includes a wheel reducer, a brake assembly, a hub assembly, a steering knuckle, a support shaft assembly, a wheel drive shaft, an upper arm coupling assembly, a lower arm coupling assembly, and a support shaft assembly A hollow shaft, the wheel drive shaft passes through the interior of the support shaft assembly and is connected to the wheel reducer, and the hub assembly is mounted on the support shaft assembly. Drive axle - Function: The drive axle is at the end of the powertrain and its basic function is to increase the torque from the drive shaft or transmission and to distribute the power to the left and right drive wheels, The vertical, vertical and lateral forces between the road and the frame or body. Drive axle generally by the main reducer, differential, wheel drive and drive axle and other components.
