The front axle is a complex of vehicle assemblies, which receives the load from the frame through the suspension and transfers it to the steered pair of wheels, and from them the lateral and circumferential forces - to the body. Front-wheel drive transmits torque from the gearbox to the drive wheels (via intermediate elements).
Instructions
Step 1
Before engaging the front axle, appreciate the significant benefits of front-wheel drive vehicles. First, they use half the number of parts, which makes the interior of the car more spacious than that of rear-wheel drive vehicles. Second, a front-wheel drive car makes it easier to drive on slippery roads: the main load is concentrated on the front axle, which allows a skilled driver to keep the car on ice.
Step 2
Please note: for most foreign-made cars, the drive axle is permanent (some have a front axle, and some have a rear axle), the second is switched on as needed. To turn on all-wheel drive on such a car (in other words, additionally turn on the front or rear axle), press the 4WD button or move the special lever to the appropriate position. Thereafter, the hydraulic as well as electrical devices will turn on the second axle.
Step 3
To connect an additional drive in off-road conditions, the classic version is used - part-time: the bridge is switched on manually. The peculiarity of this system is that when a certain speed is reached (some car models have 40 km / h, and the other - 60 km / h), the additional wire is automatically disconnected.
Step 4
For vehicles produced earlier, the drive is engaged by moving the transfer case lever to the 4WD position.
