What is the maximum grade???

Maximum climbing capacity when the car is fully loaded.

The maximum climbing degree of the car refers to the maximum slope that the car can overcome with the first gear on a good road surface when the car is fully loaded, which characterizes the climbing ability of the car. The gradeability is expressed as the angular value of the slope (expressed in degrees) or as a percentage of the height difference between the start and end points of the slope and its horizontal distance (tangent).

Car gradeability expresses the car's ability to climb hills. The car can climb uphill only if the car traction is greater than the uphill resistance and rolling resistance (air resistance is not counted). The measurement method of expressing the climbing ability of this car is the percentage slope, which is expressed by the ratio of the height of the slope to the horizontal distance, that is, the percentage slope tan 100%, where is the angle between the slope and the horizontal plane.

For example, "car climbing" is 30%, according to the above formula: tan 100% = 30%, that is, tan = 30 100, check the trigonometric function table to get 16°42", i.e. the steepest gradient that the car can climb is 16°42" 。

If the angle is directly marked on the "car climbability" in the car technical specification, it refers to the steepest slope that the car can climb. According to the regulations of the automotive industry, only the percentage slope is in line with the standard, and if only a number is marked, it is actually a percentage number.

To be clear, some people are wrong to interpret the percentage value of "car grade" as the direct steepest slope that the car can climb.

For cars that often drive in cities and on good roads, the maximum climb is about 10°. For trucks, sometimes it is necessary to drive on bad roads, and the maximum climbing degree should be around 30%. The off-road vehicle should be driven in a roadless area, and the maximum climbing degree should reach more than 30°.

The maximum climbing degree refers to the maximum slope that the car overcomes with the first gear on a good road surface when it is fully loaded, which characterizes the climbing ability of the car and is one of the indicators to evaluate the power of the car. The measurement method of expressing this car climbing ability is the percentage slope, which is expressed by the ratio of the height of the slope and the horizontal distance, that is, the percentage slope = tg 100%, where is the angle between the slope surface and the horizontal plane.

For example, the maximum climbing degree is 30%, according to the above formula: tan 100%=30%=, and the trigonometric function table is 16°42", the steepest gradient that this car can climb is 16°42" 。

Hello, is a measure of the car's ability to climb a hill, and slope refers to the ratio of the height of the slope to the horizontal distance. It is generally expressed as a percentage, but it is also expressed as a decimal. Note:

It is a ratio and is unitless. The angle of the slope refers to the angle between the pavement of the slope and the horizontal plane, and the unit is (°).

For example, if the slope of a certain section of the road is 30%, in fact, the vertical height rises by another 30 meters when the horizontal distance is 100 meters, but the angle of this section of the road is 16°42", instead of 30 °. And with a 100% slope, the angle of the slope is 45°.

The car's climbing angle: The extreme slope at which the car can go uphill. This is often used to measure the climbing performance of a car.

The calculation is as follows: the climbing angle of the car on the flat road is zero, and the climbing angle from the flat road to the top of the slope is the arctangent value of the height of the top of the slope and the projection of the slope section on the horizontal.

The maximum grade of a car is the maximum slope that a car can overcome when it is fully loaded. The following is an introduction to the maximum climbing ability of the slow lift:

The maximum climbing degree of the car is specifically introduced:

The degree of climb is expressed as the angular value of the slope (expressed in degrees) or the ratio of the height difference between the start and end points of the slope to its horizontal distance (tangent); In addition, the maximum climbing degree of most models and ordinary family cars is below 30 degrees, and 45 degrees is the limit of all models, and no model can climb a steep slope of more than 45 degrees.

The role of the car's maximum grade:

Car gradeability indicates the car's ability to climb hills. The car can only go uphill if the traction force of the car is greater than the uphill resistance and rolling resistance (the air resistance is not counted). The car's ability to climb a hill is measured as a percentage slope, which is expressed as the ratio of the slope height to the horizontal distance.

The maximum climbing degree refers to the maximum slope that the car overcomes with the first gear on a good road surface when it is fully loaded, which characterizes the ability of the car to climb the slope and is one of the indicators to evaluate the power of the car. The measurement method of expressing this car climbing ability is the percentage slope, which is expressed by the ratio of the height of the slope and the horizontal distance, that is, the percentage slope = tg 100%, where is the angle between the slope surface and the horizontal plane.

Explanation of the term maximum grade.

The maximum climbing degree refers to the maximum slope that the car overcomes with the first gear on a good road surface when it is fully loaded, which characterizes the climbing ability of the car and is one of the indicators to evaluate the power of the car. The measurement method of expressing this car climbing ability is the percentage slope, which is expressed by the ratio of the height of the slope and the horizontal distance, that is, the percentage slope = tg 100%, where is the angle between the slope surface and the horizontal plane.

The formula for calculating the gradeability.

For example, the maximum climbing degree is 30%, according to the above formula: tan 100%=30%=, and the trigonometric function table is 16°42", the steepest gradient that this car can climb is 16°42" 。

Two factors that affect the maximum grade.

Torque, which ensures that it does not stall during climbing, is related to engine power and no-load heavy load.

Friction to ensure that there is no slippage on the way uphill. New tires are better than old tires, tires have the best off-road tread wheels, followed by horizontal tread wheels, longitudinal tread wheels are the worst, and dry rough roads are better than wet flat roads. In this regard, rear-wheel drive is far superior to front-drive, and four-wheel drive is far superior to two-wheel drive.

The maximum climbing degree refers to the maximum slope that the car overcomes with the first gear on a good road surface when it is fully loaded, which characterizes the climbing ability of the car and is one of the indicators to evaluate the power of the car. The measure of a car's ability to climb is the slope.

This slope is not the angle of the slope as we usually understand it, but the ratio of the height of the slope to the horizontal distance, which is generally expressed as a percentage and also as a decimal. That is, slope = (height of slope horizontal distance) * 100%. A maximum grade of 30% means that the gradient is 30 meters for every 100 meters of progress.

The maximum slope of the highway is not more than a few degrees

Generally, the slope of urban roads does not exceed 5%, and more than 10% is considered a relatively large slope; The design speed of 120 mph high speed is generally not more than 5% slope. Yunnan's "Devil's Highway" has a slope of more than 8%, so accidents are frequent. In the underground parking lot, which looks very steep to us, it is actually designed to have a slope of only about 15%, which translates to an angle of about.

The maximum climbing degree of the general sedan is about 32%, and some four-wheel drive models can be higher, but due to the limitation of the body geometric size, it rarely exceeds 40%. It is important to note that the maximum climb of a car is expressed as a percentage, not the angle of the slope, and the main factors that affect the maximum climb are the engine torque and the adhesion of the car. Those who say what the maximum climbing degree of the car is, in fact, are confusing, or the basic concept is not understood.
