Technical Field
The utility model relates to the technical field of vehicles, in particular to measuring device of vehicle gesture rolls off production line.
Background
After the production line of the vehicle is off-line, the vehicle posture needs to be checked. For example, as shown in fig. 1, a worker manually drives a car to pass through a bumpy road surface, then the worker drives the car to a four-wheel positioning and headlamp adjusting station where the road surface is uneven, tires are on an elliptical machine, and the worker drives the car to level the ground after about 1 minute of adjustment, and then to a subsequent inspection line.
At present, the vehicle posture becomes one of the important standards for detecting the whole vehicle. As vehicle-mounted information, the vehicle-mounted information is as important as four-wheel positioning information, if the vehicle posture does not accord with the design, abnormal sound, shaking and the like of the whole vehicle can be caused, and whether the posture accords with the design or not needs to be known as soon as possible after a test sample vehicle is off line
However, during vehicle development, it is difficult to maintain good vehicle attitude consistency, and therefore, off-line vehicles need to be measured in the field. The current attitude angle measurement method is as follows: measuring distances d1 and d2 from the wheel center of the front and rear wheel tires to the lower edge of the wheel arch, and calculating a difference value d between the distances d1 and d 2; and calculating the attitude angle alpha as d/wheelbase, and judging whether the attitude angle alpha is in a reasonable range.

Meanwhile, the tolerance of parts and installation tolerance of the wheel arch can increase the uncertainty of data, and the record is manual record, which is not beneficial to tracing and tracking.
The relevant terms are explained as follows: vehicle attitude: generally, the vehicle is stationary on a horizontal ground and is inclined forward and backward.
Vehicle attitude angle: the included angle between the ground line and the horizontal plane under the design coordinate of the whole vehicle is indicated. The forward inclination of the vehicle is positive, and the reverse is negative; the control of the whole vehicle attitude is generally set in three states of servicing, half-load and full-load, and some situations need to consider the situations of no-load or overload and the like. Currently, the measurement postures are all in a standby (i.e. no-load) state.
