Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an apparatus for testing the running performance of automobiles, tires, etc. on a basin of water.

[Conventional technology] Because running tests on automobiles, tires, etc. require a large area, conventionally, running tests on flatbed roads have been carried out in naturally cold regions such as Hokkaido, where water surfaces are formed. We have built a road with a 300-degree road and conduct tests when the road surface is frozen in the winter.

[Problems to be Solved by the Invention] As described above, the conventional ice and snow road driving test device is limited to the cold region and the test period is limited to the winter season, and is subject to weather conditions.
It is difficult to maintain the desired road surface condition, and maintenance is time-consuming and difficult.

There were issues such as the need to move measuring equipment and personnel over long distances.

This invention was made to solve these problems, and the construction site is not limited to cold regions, and it is possible to create a basin road surface in a desired condition and conduct tests at any time. The purpose is to obtain test equipment.

[Means for Solving the Problems] The ice and snow road running test device according to the present invention has a freezing compartment installed adjacent to the running test compartment via a door, and a water basin to be filled with water to serve as a water basin formed on the upper surface. a truck; a moving means for moving the truck between the running test section and the freezing area; and an approach road formed so as to connect flush with a water basin on the truck located at a predetermined position in the running test section.

[Operation] A cart is placed in the freezing section of the basin road running test device of the present invention, and the water in the basin on the carriage is frozen by the freezing device to form a basin. At this time, it is possible to form a water basin in a desired state by adjusting the temperature etc. by operating the refrigeration equipment. When this trolley is moved to a predetermined position in the running test section by means of transportation, the run-up road and water basin will be flush with each other, so the test object is run from the run-up road, set at a predetermined speed, and enters the water basin. Tests can be conducted by driving under desired conditions on ice floes formed in desired conditions.
Desired test results can be easily obtained at any time.

[Example] Hereinafter, an example of the present invention will be described with reference to the drawings. 1st
Figures to Figures 4 show a basin road running test device according to an embodiment of the present invention, in which Figure 1 is a cross-sectional view, Figure 2 is a plan view, Figure 3 is a side view, and Figure 4 is a second embodiment. FIG. 3 is an example cross-sectional view.

In the figure, 1 is a running test section, 2 is a freezing section, 3 is a trolley, 4 is a basin or basin, 5 is an approach road, 6 is a freezing device, 8 is a door, and 9 is a running test vehicle.

The running test section 1 of this ice rock road running test device is open in the running direction where the approach road 5 is formed, and the ceiling and both sides are covered to prevent rain and wind.

There is a freezing section 2 adjacent to the running test section 1, and a heat insulating door 8 is provided between it and the running test section 1 so as to be openable and closable. The refrigeration compartment 2 is opened like a large refrigerator with an insulating roof and walls in order to form a water basin at a fairly low temperature. Rails 34 are laid across the running test section 1 and the frozen section 2, and the trolley 3 is provided so that it can be moved by opening the door 8. For example, assuming that the cart 3 passes over the water basin at a speed of 100 - in about 3 seconds, the top surface of the cart 3 has a length of 1.
A water basin 4 is provided to store water with a length of 00 m, a width of 5 m, and a depth of 10 CII. Note that the dimensions in the figure are reduced in the length direction.The cart 3 can be freely moved between the running test section 1 and the frozen section 2 by opening the door 8 by a drive device (not shown). A cooling pipe 63 is installed on the ceiling inside the freezing section 2, and a refrigerator 61 and a cooler 62 are installed outside the freezing section 2, which cool and freeze the water in the water basin 4 on the top of the cart 3 to form the ice floes 4. The height position of the top surface of the ice floe 4 of the zero bogie 3 that is designed to be formed is so that it is flush with the top surface of the approach road 5 when the bogie 3 is in the test state position in the running test section 1. It is formed. In addition, the code|symbol 32 is the wheel of the trolley|bogie 3.

Next, the zero truck 3 whose operation will be explained is put into the freezing compartment 2, the basin 4 is filled with water, the Ji8 is closed, and the freezing 816
1 is operated to cool the inside of the freezing section 2 through the cooling pipe 63 and freeze the water in the water basin 4 to form an ice disk 4. By adjusting the cooling temperature, cooling time, water condition, etc., the properties of the ice floe 4 can be made as desired. When the ice floe 4 in the desired state is formed, the door 8 is opened and the trolley 3 is moved into the running test section 1. The top surface of the ice floe 4 and the top surface of the run-up road 5 are formed so that they are flush with each other and connected, so that one run-up road 5 can be covered with ice! ! A test road was formed that passed over 4 and reached the other approach road 5.

A driving test vehicle 9, which is a test vehicle or a vehicle equipped with test tires, is driven and enters the driving test zone ■ on one approach road 5 so that it reaches a predetermined speed at the entrance of the driving test zone 1, and then enters the driving test zone ■ on one approach road 5. The vehicle runs on the ice floe 4 under test conditions, collects various travel data, and then runs onto the other approach road 5.

Tire marks remain on the ice floe 4 that the driving test vehicle 9 has passed once, so if you want to perform a test under new conditions, put the truck 3 into the freezing section 2 and readjust the properties of the ice floe 4. , the trolley 3 is moved into the running test section 1 again and the next running test is performed.

In the second embodiment shown in FIG. 4, a refrigerated section 2 is provided adjacent to both sides of the running test section 1, and there are two trolleys 3. For example, as shown in FIG. When the truck 3 is being used for testing, the left truck 3 is cooled by the refrigeration device 6 in the left refrigeration compartment 2 to adjust the ice floe 4 to the desired condition. By alternately using the left and right carts 3, it is possible to reduce idle time and perform tests efficiently.

In addition, although there are two rails 34 in the figure, in reality, several or tens of rails would be laid, or it would be simply a solid floor surface without rails.6 Also, entering the running test area 1 from the outside The end of the run-up road #r5 is extendable and retractable in the running direction, and after the trolley 3 is set at a predetermined position in the driving test zone I, the end of the run-up road 5 is pushed out, and the run-up road 5 is connected to the ice plate 4 of the trolley 3. You may also connect it to

In addition, since the ice floe 4 is artificially created with this device,
It is also possible to easily embed a sensor at any position and depth within the ice floe 4 and collect desired data.

Although it is not necessary to cover the running test area, if it is provided, it will prevent the water basin from deteriorating due to direct sunlight.
Advantages include that test measurements can be performed regardless of the weather, and there is little risk of confidential test contents being leaked to the outside.

[Effects of the Invention] As described above, according to the present invention, an ice floe is artificially formed in the frozen compartment and the ice floe is moved to the driving test compartment to perform the test, so that the location, seasonal weather, etc. Tests can be carried out by accurately adjusting and creating a water basin to meet desired conditions at any time without any restrictions or the hassle of moving personnel and equipment over long distances.
