What is the minimum ground clearance?

1, minimum ground clearance of

Minimum clearance C (as shown) in an automobile is loaded, at rest, the intermediate region (0.8b within the scope of the car on the support plane, b is the spacing distance between the edge of) both sides of the lowest point of the tire.

2. Details

on the minimum ground clearance, the previous standard, the minimum ground clearance is predetermined, probably between 150 ~ 160mm, but now the standard canceled the mandatory.

The larger the minimum ground clearance, the vehicle by an obstacle or greater ability uneven ground, but high center of gravity, reducing the stability; the smaller the minimum ground clearance, impaired by the vehicle capacity was uneven ground or weaker, but the low center of gravity for improved stability.

Minimum clearance through consideration of transport loading and unloading platform, taking into account the possibility of the car when grazing does not occur near the edge of the pavement general. If the limited sales to a country or region, but also taking into account the quality of local roads. Meanwhile, the minimum ground clearance from the value there is a certain limit, it is the function associated with the vehicle, the aerodynamics, such as the minimum ground clearance of the car will be relatively small, and the minimum ground clearance SUV will be relatively large.

3, the minimum ground clearance suv

in the SUV, the minimum ground clearance of the car often determines the capacity, and because different SUV car drive axle manner, the minimum ground clearance in the car or car is more vertical distance of the lowest part on the lower portion of the vehicle body or chassis of the lowest point of the contour of the ground, in the SUV and refers more ground the vertical distance between the front axle or the rear axle of the lowest member.

In general, the minimum clearance car 110 mm to 150 mm from the groundBetween, for example, for Audi A6 minimum ground clearance of 142 mm. For the car, the greater ground clearance (more than 130 mm), by relatively performance, but poorer high-speed stability; ground clearance is smaller (less than 110 mm), the better the high-speed stability, However, by poor. Now equipped with an air suspension models can automatically adjust the clearance, it can satisfy the dual needs of high speed and by the stability.

SUV minimum ground clearance typically 200-250 mm, e.g. Toyota Land Cruiser is 220 mm, almost twice the A6. For SUV, the ground clearance is smaller (less than 200 mm), the performance is worse, the focus road performance, i.e., in favor of urban SUV; clearance from the ground larger (greater than 250 mm), the better the performance, more emphasis on field performance, is biased towards the pure off-road SUV. Also now some high-end SUV is also equipped with height-adjustable air suspension, so that both handling and off-road.

This can be seen with the different models, the minimum ground clearance difference is great. Clearance

each car height value is not static, it depends on the load conditions. Ground clearance is thus determined depending on the change of the load, according to load changes to consider the maximum gap

4, characterized

which characterizes the ability automobile collision stones, stumps and other obstacles crossed. Vehicle front axle, the flywheel housing, the transmission case, muffler, and the main drive housing and the like usually have small clearance. Ground clearance of the front axle of the car is generally smaller than the flywheel housing, in order to use the front axle is protected from the flywheel housing weak red touch. Rear axle that has the larger diameter of the main drive gear, typically the minimum ground clearance.
