  • 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.

By strictly enforcing tneir we-ight · laws,-States could virtually eliminate damage caused by overweight trucks. While controlling truck weights will not eliminate highway deteri­ oration, applying Feaeral weight limits to all trucks on all Federal-aid highways could re­ duce it even further. National statistics show that at least 22 per­ cent of all loaded tractor-trailers exceed State weight limits. This percentage is even higher for other types of large trucks. (Seep.11.) In 1956, Congress established weight limits for interstate highways as a precondition for Federal highway funaing, but these limits ao not apply to noninterstate Federal-aid high­ ways--95 percent of the Federal-aia system. Even for interstate highways, higher weights are often allowea. The Federal investment in the Nation's nighway system, over $96 billion s~nc~ 1956, must be protectea. (Seep. 37.) eongress should amend the highway legislation 1o: · · --Make Federal weight limits also apply to noninterstate Federal-aid highways in all States. --Terminate current exceptions in Federal law that allow higher limits on some interstate highways.

  • Wl002 Installation Instructions
    WL002 INSTALLATION INSTRUCTIONS 1993-2002 Camaro, Firebird TOOLS REQUIRED: Hydraulic jack and stands or service lift Die grinder with cutoff wheel or similar cutting tool (See Step 12 below) Tin snips Wrenches and sockets: 7mm, 13mm, 15mm, 18mm, 21mm, 9/16”, ¾”, 15/16” INSTALLATION: 1. Lift vehicle and safely support with jack stands under the frame rails. 2. Position the jack under the center of the axle once the car is secure. 3. Using an 18mm and 21mm wrench, remove the factory panhard rod. 4. Locate the heat shield directly over the muffler. There are two small screws that connect the heat shield to the upper panhard rod support. Using a 7mm wrench or socket, remove these screws as shown in IMAGE 1. 5. Remove the upper panhard rod support bolt on the passenger side using an 18mm and 21mm wrench. Due to rearend/spring interference, you may need to lift or lower the rear end in order to get the bolt all the way out. (IMAGE 2) 6. Using a 15mm socket, remove the (3) bolts on the drivers’ side that connect the upper panhard rod support to the frame rail. Remove the upper panhard rod support. 7. Using the 7mm socket, remove the remaining 3 screws that retain the heat shield to the floor. Remove the heat shield by sliding out the rear. 8. Install the BMR Watts Link cross-member with the supplied spacers installed where the panhard rod and upper panhard rod support was originally bolted. See IMAGE 3). Use the factory mounting hardware to install the cross-member.
