  • What You Need to Know About Mounting Radial Tires on Classic Vehicle Rims
    What You Need to Know About Mounting Radial Tires on Classic Vehicle Rims Over the past 100 years, tires, and the wheels that support them, have gone through significant changes as a result of technical innovations in design, technology and materials. No single factor affects the handling and safety of a car’s ride more than the tire and the wheel it is mounted on and how the two work together as a unit. One nagging question that has been the subject of a lot of anecdotal evidence, speculation, and even more widespread rumor is whether rims designed for Bias ply tires can handle the stresses placed on them by Radial ply tires. And the answer is - it depends. It depends on how the rim was originally designed and built as well as whether the rim has few enough cycles on it, and how it has been driven. But most importantly it depends upon the construction of the tire and how it transmits the vehicle's load to where the rubber meets the road. In this paper, we want to educate you on the facts - not the wives tales or just plain bad information - about how Bias and Radial tires differ in working with the rim to provide a safe ride. Why is there a possible rim concern between Radial and Bias Tires? The fitting of radial tires, to wheels and rims originally designed for bias tires, is an application that may result in rim durability issues. Even same-sized bias and radial tires stress a rim differently, despite their nearly identical dimensions.

  • A Review of Rear Axle Steering System Technology for Commercial Vehicles
    연구논문 Journal of Drive and Control, Vol.17 No.4 pp.152-159 Dec. 2020 ISSN 2671-7972(print) ISSN 2671-7980(online) http://dx.doi.org/10.7839/ksfc.2020.17.4.152 A Review of Rear Axle Steering System Technology for Commercial Vehicles 하룬 아흐마드 칸1․윤소남2*․정은아2․박정우2,3․유충목4․한성민4 Haroon Ahmad Khan1, So-Nam Yun2*, Eun-A Jeong2, Jeong-Woo Park2,3, Chung-Mok Yoo4 and Sung-Min Han4 Received: 02 Nov. 2020, Revised: 23 Nov. 2020, Accepted: 28 Nov. 2020 Key Words：Rear Axle Steering, Commercial Vehicles, Centering Cylinder, Tag Axle Steering, Maneuverability Abstract: This study reviews the rear or tag axle steering system’s concepts and technology applied to commercial vehicles. Most commercial vehicles are large in size with more than two axles. Maneuvering them around tight corners, narrow roads, and spaces is a difficult job if only the front axle is steerable. Furthermore, wear and tear in tires will increase as turn angle and number of axles are increased. This problem can be solved using rear axle steering technology that is being used in commercial vehicles nowadays. Rear axle steering system technology uses a cylinder mounted on one of rear axles called a steering cylinder. Cylinder control is the primary objective of the real axle steering system. There are two types of such steering mechanisms. One uses master and slave cylinder concept while the other concept is relatively new. It goes by the name of smart axle, self-steered axle, or smart steering axle driven independently from the front wheel steering. All these different types of steering mechanisms are discussed in this study with detailed description, advantages, disadvantages, and safety considerations.

  • The Self-Steering Axles
    THE SELF-STEERING AXLES R O A D R A N G E The costs for fuel and maintenance of vehicles are an increasing component of the running costs for a transport company. > Fuel economy. Fuel prices are influencing the costs of transport. Something can be done only by reducing consumption. The steering axle greatly improve the performance of trailers and semi-trailers, especially over mixed routes, the motor vehicle is less stressed, and reuces fuel consumption. > Lower expenses for the tires. Thanks to steering axles tyres have a longer life: a double benefit for the carriers who drive more kilometres with a set of tyres and have less downtime, because steering axles save the tyre wear. Even recycled tires can be used with increased safety. > Smoother and safer drive. The characteristics of the steering axle are useful especially when great manoeuvrability and flexibility are required - for example in local traffic and of distribution: precise manoeuvres, less damage from bumps, more safety and efficiency. The device for the wheels’ alignment and pneumatic latch are an useful aid for precision and safety also when reverse driving. > ADR range of steering axle.

  • Standards and Requirements for Scrap Tire Transporters
    Division of Materials and Waste Management December 2018 Guidance Document #640 Standards and Requirements for Scrap Tire Transporters Purpose This educational guideline addresses owner and operator responsibilities when registering and operating a scrap tire transportation business which either picks up tires in Ohio or delivers tires to an Ohio destination and is intended to guide readers through some of the major requirements of the scrap tire rules. However, it is only a guide and the appropriate sections of the Ohio Administrative Code should be read in their entirety. Applicable Rules and Statutes Ohio Revised Code 3734 Ohio Administrative Code 3745-27-54 through 3745-27-56 Who must register? Chapter 3734.83 of the Ohio Revised Code states that “….no person shall transport scrap tires anywhere in this state unless the business or governmental entity that employs the person first registers with and obtains a registration certificate from the director of environmental protection.” It should be noted that there are several exclusions from the requirement to become a registered scrap tire transporter which are outlined below. However, if a transporter does not meet one of the specific exclusions provided below, then registration with Ohio EPA is required. The requirement to become a registered scrap tire transporter is not required if any of the following apply: 1. If 10 or less scrap tires are transported per load; 2. If tires are transported only for the transporter’s own agricultural use or in producing or processing aggregates; 3. If the transporter is a solid waste hauler who transports 10 or fewer tires which are incidental to the solid waste load; 4.
