Vehicle body height measuring device and vehicle counterweight quick measuring method

Abstract

The invention relates to the field of vehicles and discloses a vehicle body height measuring device and a vehicle counterweight quick measuring method. The vehicle body height measuring device comprises a positioning rod, a measuring rod and a connecting rod vertically connecting the positioning rod with the measuring rod, the positioning rod and the measuring rod are parallelly arranged, the connecting rod is extensible, and a level is arranged on the connecting rod. A distance from the center of a hub to a hub cap before and after a vehicle is counter-weighted can be quickly measured through the positioning rod, the measuring rod and the extensible connecting rod, and requirements on levelness of the ground in the process of measuring are low, so that compression amount of suspensions can be acquired quickly and accurately, and counterweight of the vehicle can be calculated through the compression amount of the suspensions; the compression amount of each of the left and right suspensions of the vehicle can be measured respectively to judge whether the vehicle is counter-weighted uniformly or not.

Description

technical field [0001] The invention relates to the field of vehicles, in particular to a vehicle body height measuring device and a method for quickly measuring vehicle counterweights. Background technique [0002] When a vehicle is performing a road test or measuring basic performance parameters, it generally needs to be counterweighted to a half-loaded or full-loaded state. The mass of the counterweight ranges from a few hundred kilograms to several tons. At present, there is no method to quickly determine the state of the counterweight of multiple vehicles and whether the mass distribution is uniform. [0003] Existing measuring method has two kinds, one is to weigh the weight of the counterweight with a floor scale, distribute it evenly on the vehicle, and then visually check whether the vehicle is level. The second is to place the vehicle with the same weight counterweight on the level ground and use a tape measure to measure the relative height between the same posit...

Problems solved by technology

[0004] In order to measure the vehicle’s counterweight and whether it is level after the vehicle’s counterweight, the above-mentioned measurement methods using visual inspection and a tape measure cannot quickly determine whether the vehicle’s counterweight and its left and right masses are even. During the measurement process, it is necessary to ensure that the ground is absolutely level. Due to the deformation of the tire under pressure, it will cause certain interference to the measurement
