Vehicle trafficability measuring device and method

Abstract

The invention discloses a vehicle trafficability measuring device, which comprises a bottom plate, a measuring plate vertically supported at one end of the bottom plate and provided with a graduated scale; a supporting rod supported on the bottom plate in a sliding mode, perpendicular to the bottom plate, being able to horizontally slide along the bottom plate and provided with a vertical sliding groove, a pin shaft arranged in the vertical sliding groove in a sliding manner, a measuring rod having one endslidably supported on the measuring plate, being able to vertically slide along the measuring plate, and having the middle point hinged to the pin shaft, a sliding rod having one end slidably supported on the measuring plate and vertically sliding along the measuring plate, the other end hinged to the pin shaft, and the length being half of the length of the measuring rod, and an angle scale fixedly connected with the pin shaft. The device is compact in structure, convenient to operate and use and low in cost, can be used for measuring the minimum ground clearance, the approach angle and the departure angle of the vehicle, is relatively accurate, effectively simplifies the passing ability measurement process, and improves the working efficiency.

Description

technical field [0001] The invention relates to the technical field of automobile detection, in particular to a vehicle passability measuring device and method. Background technique [0002] The passability of a vehicle is an important performance of a vehicle, an important characterization parameter of the vehicle's traffic capacity, and an important parameter to characterize whether a vehicle can pass through low-lying and convex road sections. At present, all domestic vehicle products must meet national standards before leaving the factory. The technical requirements of passability, therefore, when the vehicle is developed or tested, it is essential to measure the passability of the vehicle. The passability measurement includes the minimum ground clearance of the vehicle, the measurement of the approach angle and the departure angle, and the existing measurement In the method, it can be measured with the help of a general measuring instrument, but it is complicated to ope...

[0002] The trafficability of a vehicle is an important performance of a vehicle, an important characterization parameter of a vehicle's traffic capacity, and an important parameter that characterizes whether a vehicle can pass through low-lying and raised road sections. At present, all domestic vehicle products must meet national standards before leaving the factory. Passability technical requirements, therefore, in the development or testing of vehicles, it is essential to measure the passability of the vehicle, the passability measurement includes the minimum ground clearance of the vehicle, the measurement of the approach angle and departure angle, the existing measurement In the method, it can be measured with the help of general-purpose measuring tools, but the operation is complicated, and multiple passing parameters need to be measured separately by multiple devices or instruments. During the measurement, the detection equipment or devices need to be replaced frequently, the operation is cumbersome, and the efficiency and accuracy are low.
