DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention is a test for measuring the characteristics, load durability, etc. of endless trackless strips generally made of rubber composite materials used in snowmobiles. It's about machines.

Conventional technology Conventional trackless strip testing machines include those that drive the trackless strip by pressing it onto multiple rows of rollers or rubber tires, and those that drive the trackless strip by placing the test object on an endless belt with a drive mechanism. Something like a palm dynamometer to evaluate its performance (Special Publication No. 52-17282)
(No. Publication) is generally known.

Problems to be Solved by the Invention In the former test machine, which uses rollers or rubber tires as a simulated road surface, the road surface such as rollers and trackless strip only partially contact each other, and when running at high speeds, the test machine becomes useless. A flapping phenomenon occurs in the areas where the rail strip is not in contact with the road surface, and this causes a force greater than the load to be applied to the entire device, making it impossible to conduct an actual running test. Therefore, even though testing at low speeds is possible, There is a problem in that it is not possible to test at high speed and under actual load conditions.

In the latter case, the simulated road surface is fixed and firmly supported, and there is no freedom of movement in the vertical or longitudinal directions, and although it can withstand use in low-speed driving tests (several 10 km/h), In the case of high-speed tests of up to 200 km, it is not possible to conduct high-speed running tests because the large vibrations generated in the trackless strip cannot be absorbed and damage equipment parts such as bearings. Since this was a test machine with a large scale, the equipment was large-scale, and it was impossible to test only trackless belts.

Means for Solving the Problems As a means for solving the problems of the prior art, we have proposed a test part equipped with a suspension mechanism for suspending a trackless strip, which is a test object, and a drive mechanism for driving the trackless strip. In a trackless strip test machine, in which a simulated road surface section equipped with an endless belt suspended by front and rear belt pulleys and a drive mechanism for driving the endless belt was installed so as to be opposed to the bottom of the endless belt, the simulated road surface section is suspended by a frame that can be lifted and lowered, an air spring that can adjust the internal pressure is interposed between the lifting frame and the pseudo road surface section, and the lifting frame and the pseudo road surface section are connected to a swingable link. This is a test machine for trackless belts, which is characterized by being connected to the ground.

Effect With such a configuration, after the elevating frame is raised and the trackless strip is brought into pressure contact with the pseudo road surface section, the trackless strip can be easily brought into a predetermined position by adjusting the internal pressure of the air spring. A load can be applied. Furthermore, due to the action of the air spring and the swingable link, the simulated road surface section has a structure that allows freedom in vertical movement but restricts movement in the longitudinal direction, which makes it difficult to perform high-speed driving tests. It becomes possible. That is, in the present invention, the movement of the simulated road surface part in the front and back direction is restricted by the action of the air spring and the link, and at the same time, it is made to have a degree of freedom in the vertical direction, so that the force in the front and back direction that occurs during the running test is (Frictional force) can be stably maintained by the link, and vibration can be absorbed by the air spring. Therefore, even if the vibrations generated during the high-speed running test become large, the test can be performed without damaging the mechanical components.

As shown in FIG. 2, the pseudo road surface section 3 is
It consists of an endless belt 22 suspended between a front belt pulley 20 and a rear belt pulley 21 attached to the front and rear of a support frame 19. The rear belt pulley 21 is attached to be movable back and forth by a tension adjustment mechanism 23. The support frame 19
A large number of support rolls 24 are attached to the upper edge to support the lower surface of the endless belt 22 and prevent the endless belt 22 from being bent. The front belt pulley 20 is
In order to drive the endless belt 22, the frame 1
It is designed to be driven via a drive mechanism consisting of a motor 25, a shaft 26, a speed increaser 27, a universal joint 28, etc. on the motor 5. The support frame 19 is integrally fixed to a base 29, and the base 29 is supported by an elevating frame 31 via an air spring 30. In this way, the pseudo road surface section 3 is provided on the elevating frame 31 with the air spring 30 interposed therebetween. The elevating frame 31 is suspended from the upper frame 1a via a threaded rod 32.
A screw rod 33 is screwed onto the screw rod 32 on the upper frame 1a, and the screw rod 33 is simultaneously rotated by a lifting motor 34 via a relay rod 35, thereby raising and lowering the screw rod 32. It's getting old.
A link 36 has one end pivotally supported by a bracket 37 fixed to the elevating frame 31, and the other end of the link 36 is pivotally supported by a pin 38 of the support frame 19. As a result, the pseudo road surface section 3 can move freely in the vertical direction, but its movement in the front-rear direction (left-right direction in FIG. 2) is restricted. The link 36 is detachable from the pin 38, and when replacing the endless belt 22, it is removed from the pin and swung downward.

Next, the operation will be explained. After the lifting frame 31 is raised by the lifting motor 34 and the endless belt 22 is brought into contact with the trackless strip 14, compressed air is supplied to the air spring 30 and the trackless strip is adjusted by adjusting the internal pressure of the air spring. A predetermined load is applied to 14. That is, the air spring 30 performs fine adjustment of the load. Next, the motor 16 is driven to rotate the trackless belt 14 in the direction of the arrow, and at the same time, the motor 25 is driven to rotate the endless belt 22 in the direction of the arrow. The speed of the motor 25 is adjusted so that the speed of the endless belt 22 is slower than the speed of the trackless band 14, so that a load (brake) is applied to the trackless band 14. This makes it possible to measure various characteristics, such as loss, workload, efficiency, and long-term durability, under the same conditions as when a snowmobile runs at high speed on a road surface.

Effects of the Invention As described above, according to the present invention, an endless belt is used as the pseudo road surface section and is driven.
In addition, while regulating the front and rear directions of this pseudo road surface, we also gave it a degree of freedom in the vertical direction and pressed it against the trackless strip, making it possible to perform performance and durability tests under high loads at high speeds of 200 km/h or more. By adjusting the internal pressure of the air spring, it is possible to easily apply a predetermined load to the trackless strip, which simulates the situation when a snowmobile travels at high speed. This method has the advantage that various properties of the strip can be measured easily and accurately.
