Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a braking force test apparatus,

More particularly, the present invention relates to a braking force testing apparatus and method for a two-wheeled automobile. More particularly, the present invention relates to a braking force testing apparatus and method for a two- The correction value of the slip coefficient of the tire is calculated by the correction value calculation unit, the correction value is corrected by the braking force measurement unit, and then the braking force of the two- According to the inspection, it is possible to correct the slip phenomenon at the time of measuring the braking force of the tire in the two-wheeled automobile, thereby accurately checking the tire braking force of the two-wheeled automobile to improve stability, increase the reliability of inspection, The present invention relates to an apparatus for inspecting a braking force of an automobile and an inspection method thereof.

Generally, two-wheeled vehicles such as motorcycles use various types of inspection apparatuses for various performance tests for the safety of the two-wheeled automobiles in the vehicle inspectors, maintenance companies, and producers of two-wheeled vehicles.

Among the performance tests of these two-wheeled vehicles, it is the braking force test to check the tire braking power of the two-wheeled vehicle to play the most important role in the safety of the two-wheeled vehicle.

The braking force is one of the most important safety factors with the ability to stop the motorcycle that the driver is driving.

In recent years, as the speed of the two-wheeled vehicle has been improved through the weight reduction of the two-wheeled vehicle due to the high output of the engine, a strong braking force is required.

As such, the factors affecting the braking power of the two-wheeled vehicle vary. Three important factors are the road surface condition of a two-wheeled vehicle, the tire condition of a two-wheeled vehicle, and the performance of a braking device mounted on a two-wheeled vehicle.

In order for the two-wheeled vehicle to exhibit the optimum braking force, the above-mentioned three factors must be in the best condition.

However, the road surface condition during the driving of a two-wheeled vehicle is a factor that changes according to the driving environment, and the driver can not arbitrarily adjust it. However, the tire condition of the two-wheeled vehicle and the performance of the braking device of the two-wheeled vehicle can always be kept in the best condition by the inspection and arrangement of the usual two-wheeled vehicle.

In most countries, periodic inspections are carried out to ensure the safety of motorcycles, as the driver may not be able to maintain the tire condition and braking system performance at all times in the best condition.

Conventionally, a braking force test apparatus and a test method for a two-wheeled vehicle test a braking force by operating a brake while the tire is mounted on a rotating member.

However, there has been a problem in that accurate and precise braking force test can not be performed as a slip or slip occurs with respect to a rotating member of a tire.

In addition, the conventional braking force testing apparatus and method of a two-wheeled vehicle have a problem in that the reliability of the braking force test is reduced as the tire slip coefficient is not corrected.

Further, unlike a conventional vehicle having four wheels, the conventional braking force testing apparatus and method of a two-wheeled automobile use a device having a complicated structure for fixing a two-wheeled vehicle in order to prevent a two- The manufacturing cost, inspection cost, and inspection time of the braking force testing apparatus of the two-wheeled vehicle increase.

In addition, since the conventional braking force testing apparatus and testing method of a two-wheeled vehicle can not efficiently arrange the components in the minimum space, the size of the testing apparatus is large and a lot of space for installing the testing apparatus is required. There is a problem that the time and resources are wasted and the driver is inconvenienced because the driver must visit the specific place for inspection.

First, the control unit 40 stores data related to the two-wheeled vehicle in the data storage unit 41. Then, the tire 2 of the two-wheeled vehicle is seated on the first roller portion 23 and the second roller portion 24 of the driving portion 10. At this time, the elastic member 45 elastically supports the link portion 32 of the rolling portion 30 so as to rotate in the direction of the second roller portion 24, so that the contact roller portion 34 contacts the first roller portion 23, And the tires resting on the first and second roller portions 23 and 24 come into close contact with the contact roller portion 34 while pressing the contact roller portion 34 . Further, the shaft weight of the tire is measured by the weight measuring instrument 60 provided in a part of the housing part 10. [

In this state, the power transmitting portion 21 is operated. When the power transmitting portion 21 rotates, the rotational driving force is transmitted to the decelerating portion 22 and the first roller portion 23 is rotated by the rotational force decelerated by the decelerating portion 22, The second roller portion 24 rotates in cooperation with the second roller portion 24.

Thereafter, the rotation of the first roller portion 23 and the second roller portion 24 causes the tire 2 to rotate. As the tire 2 rotates, the contact roller portion 34 ) Rotate equally at the same speed as the tire 2.

In this state, when the braking device of the two-wheeled vehicle is operated, the braking force is generated. This braking force drives the braking device to operate between 100N and 500N depending on the test conditions. Also, the maximum braking force is measured.

When the braking device is operated, a braking force is generated in the tire 2, and accordingly, a braking force is also generated in the contact roller portion 34. [ The braking force is also generated in the first roller portion 23 and the second roller portion 24 but the contact roller portion 34 and the first roller portion 23 and the second roller portion 24 are different from each other The number of revolutions is obtained.

The rotation number measuring section 42 detects the number of rotations of the first roller section 23 or the second roller section 24 and the contact roller section 34 in accordance with the signal of the sensor or the encoder by the signal of the control section 40 . The rotation speed detected by the rotation speed measurement unit 42 is transmitted to the correction value calculation unit 43 through the wired or wireless communication unit.

The correction value calculation unit 43 calculates the correction value of the slip coefficient of the tire according to the rotation number of the rotation number measurement unit 42 and transmits it to the braking force measurement unit 44 via the wired or wireless communication unit.

The braking force measurement unit 44 measures the braking force after correcting the correction value calculated by the correction value calculation unit 43. [

The braking force measured by the braking force measuring unit 44 is transmitted to the comparing unit 45 through the wired or wireless communication unit.

The comparison unit 45 compares the braking force measured by the braking force measurement unit 44 with the braking force stored in the data storage unit 41 to display graphs and numerical values of the normality and braking force on the display unit 46, And the display unit 46 displays it on the monitor.

In the same manner, the braking force of the rear tire of the two-wheeled vehicle is measured.

As described above, the two-wheeled motor vehicle braking force test apparatus and method according to the present invention not only improves the reliability of the braking force measurement but also measures the braking force accurately by correcting the slip coefficient in real time, The braking force test apparatus of the two-wheeled vehicle can be installed not only in a fixed place but also in a movable module, thereby improving convenience for the driver and improving safety.
