This is the civil engineering questions and answers section on "Railways" with explanation for various interview, competitive examination and entrance test. All Rights Reserved. Is there a solution to fix the problem? 28. the track. View Answer Discuss in Forum Workspace Report. While on curved path, the outer wheel has to cover larger distance than the inner wheel. I probably. The wheels of a railway vehicle are fixed to a single axle and rotate together. This, however, becomes impossible for the vehicle as a whole since the rigidity of the wheel base causes the trailing axle to occupy a different position. It maintains vehicle in the central position w.r.t. In coning of wheel the tread or rim of wheels of railway vehicles is made in the shape of a cone with the slope of about 1 in 20. B. Spin, the scooter company owned by Ford, is testing a new scooter that can be controlled by a remote operator. Let us discuss. In order to minimize the disadvantages caused by coning of wheels, the rails are tilted inwards at an angle of 1 in 20. The smooth flow of train on the tracks is made possible by coning of wheels and by providing cants. They come in every color of the rainbow. What is a Ground Source Heat Pump? The overall length of a turn out is the distance between the end of stock rail and, According to Railway Board, no diamond crossing should be flatter than, A scissors cross over consists of one diamond and. Some wheel-end parts can be re-used — provided they are thoroughly inspected and still in good condition and within spec. The machine spins the assembly at very high speed to determine the heaviest point and then tells the operator where and how many weights to place on the opposite side to compensate. Although the hub should not ride on the body, it will make intermittent contact as the car moves down the track. (iii) Coning also prevents, to some extent, the slipping of the wheels. Coning of wheels is provided A. to check lateral movement of wheels B. to avoid damage to inner faces of rails C. to avoid discomfort to passengers D. All the above. autodesk-fusion360-header-nav-label.product-name ... AFAIK the purpose of the coning on loco wheels is to centralise the two wheels on the track when running in a straight line but also to give a differential action to the wheels when they are going … Workspace. Coning of Wheels 19. The good news is there is an easy way to prevent this problem. A certain amount of clearance had to be allowed between the flanges and the rails, so that any slight misalignment did not cause the … They are today almost universally used in the front suspension, having replaced the kingpin/linkpin or kingpin/trunnion arrangement, but can also be found in the rear suspension of a few higher-performance autos. 5 Tips to Prevent Wheel Separation. (i) Coning the wheels reduces the depreciation of the wheel rims and rails. In order to minimize the above mentioned disadvantages, the Tilting of Rails is done. While on curved path, the outer wheel has to cover larger distance than the inner wheel. Is it possible to create a tangent joint between a rail and wheel as illustrated below - so that the wheel will roll along the rail? Due to the coning of wheels, the outside wheel travels a longer distance compared to the inner wheel. Contrary to popular belief, the flanges should not touch the rails. Some wheel-end parts can be re-used — provided they are thoroughly inspected and still in good condition and … Wheel coning is the process of modification of the inside wheel hub to reduce hub-to-body contact area and thereby the drag. A wheel's urethane formula dictates just as much about the way the wheel performs. Thus, the A scissors cross over consists of … How does this image enhance the information provided in the book? Flanges as shown in figure are only a last resort to prevent the wheels becoming derailed - they're a safety feature. Unlike plateways, these railways did not have guidance flanges on the rails, so flanges had to be provided on the vehicle wheels instead. Since acceleration is … Let us know in the comments what you think about the concepts in this article! View Answer. (AP Photo/Darron Cummings, … Advantages of Coning of Wheel • Controlling differential movement of Front & Rear Axles (which is caused due to rigidity of frame & axle) thus acting as a balancing factor (on curves rear axle has the tendency to move towards inner rail) • Smooth riding as it help vehicle to negotiate curves smoothly • Reduces wear and tear of wheel flanges • Approx. Flanges as shown in figure are only a last resort to prevent the wheels becoming derailed - they're a safety feature. • On Straight & level surface: Circumference of treads of inner & outer wheels are equal. The flanges of wheel is never made flat, but they are in the shape of cone with a slope of 1 in 20. A “limited-slip differential” is employed most commonly, or a traction control system (TCS) is used to prevent wheel spin-up. On straight track, portions of wheels running on track have same diameter. Depreciation is caused because of the friction action of rims with inner faces of the rail top. Get Ready for Power Bowls, Ancient Grains and More. Coning of wheels – Straight and Curved Tracks (Courtesy :www.engineeringsall.com ) Purpose: To keep the train in its central position of the rails, coning does not allow any sidewise movement on a straight track. May 20, 2015. It maintains vehicle in the central position w.r.t. The rails are also laid at a slope of lin20 (same slope of wheel face) This is called coning of wheels. On straight track, portions of wheels running on track have same diameter. It prevents, to some extent, the slipping of the wheels. Coning of Wheel. Report errors. The pressure on the horizontal component of force near the inner edge of outer rail has a tendency to wear the rail quickly, The horizontal component has to turn the rail outwards and hence the gauge may be widened, If no base plates are provided, sleepers under the outer edge of the rail may be damaged, It increases the life of sleepers and rails. This reduces wear on the rail as well as on the tread of the wheel. Answer: Option D. Explanation: No answer description available for this question. The former is a more elaborate mechanical equivalent of the open differential which limits the wheel speed differential while the latter applies the brake to a wheel which is losing traction, to prevent it spinning up. If one were bigger than the other, the bigger wheel would go further at each revolution and would tend to overtake the smaller wheel. Discuss in Forum . Wheels can be large or small, soft or hard, with a core or not, with square edges or rounded ones. value of slip for … While on curved path, the outer wheel has to cover larger distance than the inner wheel. 9.
