Background
With the increasing popularization of domestic cars in China, consumers pay more and more attention to vehicle performance indexes, and the ground clearance of a whole car becomes one of important reference indexes for purchasing vehicles. The ground clearance standard is established in the whole vehicle framework development process, main parts and areas need to reach the standard in the design process, and the establishment of the index influences all links in the whole vehicle design process.
The ground clearance of the whole vehicle is also the expression of the passing performance of the vehicle, the passing performance of the vehicle refers to the capability of the vehicle passing various road conditions, and the passing performance of the vehicle can be divided into profile passing performance and traction support passing performance; the former is the ability of the vehicle to pass rough road sections and obstacles (such as steep slopes, side slopes, steps, trenches, etc.), and the latter is the ability of the vehicle to pass through soft soil, desert, snowfield, ice, swamp, etc. The profile passage parameters are mainly as follows: minimum ground clearance, longitudinal pass angle, approach angle and departure angle; the main evaluation indexes of the vehicle support trafficability include adhesion quality, adhesion coefficient, and vehicle ground pressure. The minimum ground clearance is more intuitive than other passing parameters, and is used by everyone to detect control passing.
The minimum ground clearance is the distance between the lowest point of the automobile except wheels and a support plane when the automobile is fully loaded and stationary, and is used for representing the capability of the automobile to pass over obstacles such as stones, stumps and the like without collision; the larger the minimum ground clearance is, the stronger the vehicle can pass through the ground with obstacles or unevenness, but the gravity center is higher, so that the stability is reduced; the smaller the minimum ground clearance, the less capable the vehicle will be to pass over obstacles or uneven ground, but the lower the center of gravity, which increases stability.
Standard number for "minimum ground clearance" is GB/T3730.3-1992, which is defined as: the distance between the most protruding part of the chassis and the horizontal plane of the automobile under the condition of full load (maximum load mass allowed) is shown in a figure form, and a specific measuring method is given, but a specific numerical range is not specified. The minimum ground clearance reflects the ability of the vehicle to pass over obstacles or uneven ground without collision. The individual height values of the ground clearance of the motor vehicle are not static and depend on the load situation. The determination of the ground clearance is therefore also dependent on the load variations, the ground clearance being taken into account in dependence on the maximum value of the load variation.
In order to ensure the riding comfort of a common automobile, a chassis is provided with a damping mechanism which comprises a damper, when the automobile runs on different rugged road surfaces, the damping mechanism can buffer the bumpiness of the road surfaces, so that the whole automobile runs stably, a pair of spears is arranged between the ground clearance and the stability of the automobile, when the ground clearance of the automobile is smaller, the automobile often breaks down when passing through a barrier or rugged road surface, even when passing through a pit road section with accumulated water, serious faults such as exhaust pipe water inflow, engine water inflow flooding cylinder damage and the like can be caused, the service performance and the trafficability of the automobile are greatly influenced, meanwhile, when passing through some barriers, the automobile can pass through the gap only by adjusting the ground clearance of the automobile at partial positions, if the ground clearance of the automobile is integrally increased for improving the trafficability, the riding comfort of the automobile is greatly reduced.
