Embodiment 1

[0060] The purpose of the present invention is to solve the problem in the prior art that the measurement device needs to rely on the action of gravity and has relatively large limitations on the test conditions. This embodiment provides a device for measuring the minimum turning diameter of a car. The device uses electricity as the driving force source, and it is convenient to take power, not limited by the weight effect, and the placement position is flexible. The driver can control the car at the same time. The operating status of the control device is also integrated with the function of a measuring ruler, which is practical and convenient.

[0061] Specifically, such as Figure 1-Figure 3 As shown, the implementation of this embodiment discloses a measuring device 1 for measuring the minimum turning diameter of a car, including: a power supply 10, and the specific power supply 10 can be an external power supply, or a cigarette lighter power supply of a car . The booster...

Embodiment 2

[0070] Such as Figure 4 As shown, the present embodiment also provides a method for measuring the minimum turning diameter of the automobile, and the measuring device 1 for measuring the minimum turning diameter of the automobile is used to measure the minimum turning diameter of the automobile by using embodiment 1 (refer to Figure 1-Figure 3 ); including the following steps:

[0071] Start the power supply 10 to supply power;

[0072] The circuit between the pressurization component 20 and the power supply 10 is conducted, the pressurization component 20 starts and pressurizes the liquid inside the liquid storage component 30;

[0073] The liquid inside the liquid storage part 30 flows to the tire 510 of the automobile through the liquid discharge pipe 40 under the action of pressure;

[0074] The tire 510 moves so that the liquid flowing onto the tire 510 forms a tire footprint circle 80 on the ground following the movement of the tire 510;

[0075] The tire footprint ...

Abstract

The invention discloses a measuring device and method for measuring the minimum turning diameter of an automobile, and the measuring device takes a power supply as a driving force source, and is convenient to take electricity. The measuring device comprises a pressurizing part, a liquid storage part and a liquid discharging pipe; one end of the liquid discharge pipe is communicated with the liquidstorage part, and the other end of the liquid discharge pipe is positioned right above the central position of an automobile tire; during measurement, a circuit between the pressurizing part and thepower supply is conducted; the pressurizing part is started and applies pressure to the liquid in the liquid storage part; therefore, liquid in the liquid storage part flows to the tire through the liquid discharge pipe under the action of pressure to form a tire mark circumference; the automobile minimum turning diameter can be obtained by measuring the circumference of the tire mark; different from the prior art, the automobile minimum turning diameter measuring device is not limited by the weight effect, the placing position is flexible, a driver can control the running state of the measuring device while operating the automobile, and the measuring device is practical and convenient.

Description

technical field [0001] The invention relates to the technical field of measuring the minimum turning diameter of an automobile, in particular to a measuring device and method for measuring the minimum turning diameter of an automobile. Background technique [0002] The minimum turning diameter of a car refers to the diameter of the trajectory circle formed by the front outer wheel, rear inner wheel, farthest point, and closest point when the car is turning and the steering wheel is turned to the limit position. The minimum turning diameter of a car is an important index to measure the flexibility of a car. Car manufacturers strictly control this index in the R&D stage. In the production stage, they will test and verify the goals designed in the R&D stage. However, the existing measurement devices need to rely on gravity. The effect can be realized, and the limitations of the test conditions are relatively large. [0003] Specifically, the existing automobile turning diamete...
