Tubeless tires mounted machine the successful development of a fetus

With the rapid development of automobile market demand for a large bearing capacity, wear polish, off-road performance, and reliability of the use of tubeless tires vacuum increasingly in a variety of car models on widely used.

As the tire (18-22? 5-20PR) fan-rise multi-line (22 layers), their wall thickness up to more than 50 mm of high intensity, at the same time due to the use of tubeless sufficient pressure, tire and rim in the mouth The outer diameter with the design selected to bear a larger amount (radial 60 mm). Therefore, the tire rim into the operating procedures at large has become more difficult to achieve using the unit's work.

To address constraints in the development of products for civilian use problems, a Space Academy special vehicle division's leadership of the Thai Ministry of the development process instructions a tubeless tire mounted machine-child. There is no one in information technology, the tires do not have the disassembly equipment manufacturing industry experience and principle, the Technology Department to overcome difficulties and give full play to our talent, in just 10 days to complete the design drawings and associated Department of rooms and the cooperation of the workshop by the end of January this year in the special car workshop to complete the first round of the tubeless tire tires mounted machine assembly work of the trial. After test equipment, at the end of the tire inner side easily into the mouth, the second tire mounted inside the mouth when the direction of the left circle about one-quarter did not enter the rim, as part of the rack into the slider less rigid arm, Lead to slide into the rim and slide cards have a lag, so that the rotation of the rim underemployment appears to be the driving force, together with operators not to use the equipment and experience, resulting in the rack compress the fuel tank arm variant . Finally, the operator of the co-ordination of human, barely two days to complete the installation of 14 tires.

Surrounding the trial in the first round of the existing problems in the Department of Technology and listen to car shop workers to seek special master's recommendations, based on the equipment to carry out a second round of the improvements were to take the following four measures:

The first is to increase the output power of the hydraulic motor; slider into the second, under the arm-plus-one oblique reinforcement, and to increase the hinge of a seat, single point of support by two points to support and enhance the rigidity of the arm And stability; finishing third, a slider into the shape of the curve, and further reduce its resistance to slide into the rim of the tank set lead into the steel rollers to reduce their friction with the rim of the contact, and prevent To overcome the tire too much power and flexibility caused by the phenomenon of death card; four in the rotation of the arm opposite the legislation to add a fixed column, so that the tire pressed the fuel tank of the single-column-mounted cantilever force for change in the goal column style Stress way to avoid because of a tire to overcome the hardness of its own arising from the thinning of the excessive pressure caused by the change rack.

In early March to complete the rectification work. After several test equipment, as the operator of the experience matured, the tire is also working to install more smoothly. Four or five individuals operating from 40 to 50 minutes a loaded, three-to 10 ~ 15 minutes a loaded. If the hydraulic pressure control valve installed in the modified, can also be changed to two-person operation by the three operations. The use of the processing performance and quality has achieved the major goals and meet the requirements of use. To ensure that the tire and rim of the injury intact, more than other manufacturers.

The successful development of the tooling equipment for the company's products in the application of fetal laid the foundation for a vacuum to fill the current vacuum in Shandong province in the fetal models equipped with devices to a blank, to address the development of products for civilian use is a major problem, according to the on-line foreign Prices of such information, the tubeless tires mounted machine for the successful development of enterprise funds to purchase equipment to save 170,000 yuan.
