A selectively operable pressure reducing valve (41) is in circuit with a pressure air source, air springs (7C, 8C) of the rear axle (7"') and with first and second valves (23, 32), selectively operated by a third valve (39), which are in circuit with the air springs (7C, 8C ; 7B, 8B ; 7A, 8A) of the rear axle (7"') and the other axle(s) (7", 7). Operation of the first and second valves (23, 32) isolates the air springs (7C, 8C) of at least the rear axles (7"') from those of the other axle or axles (7", 7') and connects the pressure reducing valve (41) to the latter air springs (7B, 8B ; 7A, 8A) so as to lower the air pressure in those air springs. -
Active Air Suspension System
IJSRD - International Journal for Scientific Research & Development| Vol. 6, Issue 05, 2018 | ISSN (online): 2321-0613 Active Air Suspension System Suchit Naresh Moon Department of Mechanical Engineering Nagpur Institute of Technology, India Abstract— Air ride suspension carries the load on each axle with a pressurized air bag just as a high pressure balloon. This system provides the smoothest and most shock free ride of any of the known vehicle suspension system. An air suspension includes a multiple air spring assemblies that each includes a piston airbag and a primary airbag mounted over the piston airbag. The primary and piston airbags each have a variable volume that is controlled independently of the other for active suspension control. Air ride system provides some important following features: 1) The system automatically adjusts air pressure in the air bag so that the trailer always rides at the same height, whether lightly loaded or heavily loaded. 2) The higher air bag pressure associated with higher trailer loads automatically provides a stiffer suspension which is required for a smooth ride. 3) The lower air bag pressure for lightly loaded conditions automatically provides for a softer suspension, thus providing the same ride quality for all trailer loading conditions. Since each axle is independently supported by its own air bag, Fig. 1: Locating Suspension Units the air ride suspension is known as fully independent suspension system. The automatic control of the air bag II. FULLY ACTIVE SUSPENSION SYSTEM pressure is accomplished by a solid state electronic control system specifically designed and packaged for vehicle use.

Royal-Enfield-Classic
about seventy on freeways…at least you won’t be getting any speeding tickets. Weighing in at 425 lbs. with a 3.56 gal- lon tank and claimed 75 mpg, the Classic 500 puts others to shame in the mileage depart- ment. Anyone looking for the fastest, most comfortable, best handling, best braking motor- cycle should look elsewhere, that’s not what the Classic or Bullet is about. Riding the wave of ‘new vintage’ motor- cycles, Royal Enfield hits the mark dead center. This is a commuter bike that not only gets the job done respectably, it will steal the attention from motorcycles three times its price.

I just bought a vintage Bullet on eBay that will be prominently displayed in my living room.

BRAKING PERFORMANCE of AIR SUSPENDED CONVERTER DOLLIES Mr
Pages 319-335 BRAKING PERFORMANCE OF AIR SUSPENDED CONVERTER DOLLIES Mr. Scott McFarlane and Dr. Peter Sweatman Roaduser Research Pty Ltd ABSTRACT In 1996 the National Road Transport Committee (NRTC) released a national heavy vehicle axle Mass Limit Review (MLR). The MLR recommended an axle mass increase for axle groups suspended by road-friendly air-suspension. For an air-suspension to be classified as Road Friendly it is required to have a bounce frequency below 2.0Hz and have damping greater than 20% of critical. It is also a requirement that the suspension group achieves load sharing within 5%. Air suspended converter dollies have become popular in Australia, particularly the triaxle type. Triaxle dollies offer a productivity benefit of between 2.5 and 4.5 tonne when compared to a tandem converter dolly. There was concern that the increased mass offered to air-suspended dollies would significantly affect the performance of road trains under braking. The Roaduser Autosim Truck Engineering Dynamics (RATED) computer simulation models were used to simulate the performance of hinged and rigid drawbar tandem and triaxle dollies under braking. The results from the simulation showed that an air-suspended tandem converter dolly could pitch significantly under braking when compared to mechanically suspended dollies. Triaxle air suspended dollies were found to pitch somewhat less than the tandem air-suspended dolly and generated a lower longitudinal force in the coupling. This indicated that the triaxle dolly has better brake balance and should be encouraged by allowing the weight increase. Rigid drawbars on converter dollies reduce the amount of dolly pitch and hence have better brake balance. -

Ceramic Disc Brake Were Developed and Tested by Porsche for Their Model Porsche 911Turbo in 1990
1.1 INTRODUCTION One of the most important control systems of an automobile is Brake system. They are required to stop the vehicle within the smallest possible distance and it is done by converting kinetic energy of the vehicle into heat energy which is dissipated into atmosphere. The main requirements of brakes are given below:- The brakes must be strong enough to stop the vehicle within the minimum possible distance in an emergency. But this should also be consistent with safety. The driver must have a proper control over the vehicle during emergency braking and the vehicle must not skid. The brakes must have good antifade characteristics and their effectiveness should not decrease with constant prolonged application. The actual stopping distance of vehicle while braking depends on the following factors:- 1. Vehicle speed 2. Condition of the road surface 3. Condition of tyre 4. Coefficient of friction between the tyre and the road surface 5. Coefficient of friction between the brake drum/disc and brake lining pad 6. Braking force applied by the driver 1.2 HISTORY Disc-style brakes development and use began in England in the 1890s. The first caliper-type automobile disc brake was patented by Frederick William Lanchester in his Birmingham, UK factory in 1902 and used successfully on Lanchester cars. However, the limited choice of metals in this period meant that it had to use copper as the braking medium acting on the disc. The poor state of the roads at this time, no more than dusty, rough tracks, meant that the copper wore quickly making the disc brake system non- viable. -
