Multi-axle vehicle steel belt drive support, lateral force, rolling resistance and sideslip detection test equipment

Abstract

This invention relates to a testing equipment for multi-axle vehicles, specifically for measuring steel belt drive support, lateral force, rolling resistance, and sideslip. It belongs to the category of automotive performance testing equipment and aims to improve domestic and international testing methods, enabling simultaneous measurement of the total mass, lateral force, rolling resistance, and sideslip of multi-axle vehicles. The invention proposes a testing bench where the total mass of the vehicle is transferred to a weighing sensor via a testing slide assembly. Simultaneously, a servo motor drives a steel belt through an active roller, rotating the wheels. A lateral force sensor measures the lateral force of the multi-axle vehicle during movement; a wheel resistance sensor measures the rolling resistance of the wheels; and an electronic ruler measures the sideslip. Based on these test results, technicians can purposefully adjust relevant vehicle parameters to determine optimal structural parameters, thereby completing the adjustment and verification of the total mass, lateral force, rolling resistance, and sideslip of the multi-axle vehicle.

Description

Technical Field

[0001] This invention relates to an automotive performance testing equipment, and more specifically, to a testing equipment for multi-axle vehicle steel belt drive support, lateral force, rolling resistance, and sideslip. Background Technology

[0002] Currently, with the development of my country's automotive industry and road transportation, multi-axle vehicles are increasingly used in road freight. While the widespread use of multi-axle vehicles improves transportation efficiency and reduces costs, it also brings the widely concerned issue of traffic safety. After a period of use, these vehicles often experience abnormal wear on the steering wheel tires, which is primarily caused by wheel sideslip. Wheel sideslip includes inter-wheel sideslip and inter-axle sideslip. Wheel sideslip leads to decreased vehicle handling stability and straight-line driving performance, exacerbates abnormal tire wear, and reduces fuel economy. Furthermore, when wheel sideslip becomes excessive, it disrupts the wheel's adhesion, causing the vehicle to lose its directional driving ability, leading to vehicle imbalance and traffic accidents. To maintain multi-axle vehicles in good technical condition and ensure safe and low-consumption operation, the most effective method is to regularly inspect and maintain inter-wheel and inter-axle sideslip. Therefore, conducting research on the detection of lateral force and sideslip in multi-axle vehicles and developing an integrated test bench for detecting and adjusting lateral force and sideslip in multi-axle vehicles is urgent and necessary.

[0061] Working principle of multi-axis automotive steel belt drive support, lateral force, rolling resistance and sideslip detection and testing equipment:

[0062] Drive the multi-axle vehicle 2 onto the test bench base ground 1 as follows: Figure 1 As shown, the car's wheels are positioned on the detection unit assembly 4. The steel-based transmission belt 62 in the detection unit assembly 4 drives the car wheels to rotate. The lateral force generated during the car's movement is transmitted through the detection slide assembly 6 to the lateral force sensor assembly 46, measuring the lateral force of each wheel. The rolling resistance is transmitted through the detection slide assembly 6 to the force sensor 73 in the motor reducer and force transmission arm assembly 63, measuring the rolling resistance of the wheels. The sideslip is transmitted through the detection slide assembly 6 to the electronic ruler 11, which measures the sideslip distance traveled by the wheels. Simultaneously, the total mass of the car is transmitted through the detection slide assembly 6 to the guide rail slider and weighing sensor assembly 47; the sum of the measurements from multiple sensors represents the total mass of the car. Based on the above test results, technicians can adjust the relevant structural parameters of the car to determine reasonable positioning parameters, thereby completing the detection of the total mass, lateral force, rolling resistance, and sideslip of multi-axle vehicles.
