What is the concept of multi-axle vehicle?
a motor vehicle with more than two axles. Because of the distribution of the vehicle’s weight over a greater number of axles, such vehicles usually have greater load-carrying capacity and better off-road performance than the two-axle types. However, their purchase and operating costs are higher.
How do you calculate each axle load?
Multiply the center of gravity distance times the weight to get the moment for each component and item. Add all of the moments and divide by the wheelbase to get the weight on the rear axle. Subtract the rear axle weight from the total weight to get the front axle weight.
What is the advantage of multi-axle bus?
Smoother Ride: Vehicles with more and independent axles handle bumps well because a bump on one wheel will not affect the opposite wheel. When combined with good truck shocks, a multi-axle vehicle will be a more comfortable drive.
Is bus a multi-axle vehicle?
A multi-axle bus is a bus or coach that has more than the conventional two axles (known as a twin-axle bus), usually three (known as a tri-axle bus), or more rarely, four (known as a quad-axle bus).
Which bus is better Volvo or Scania?
Scania has a narrower body when compared to Volvo. The Scania Metrolink also looks a little taller that its competitor. Also, the windows on the Volvo are quite larger as compared to Scania. Both the buses are mounted with a rear engine, so there isn’t much on the exterior bit from a passenger point of view.
How long is a tri axle coach?
Built on a stainless steel chassis, the 12.5m-long bus includes a rear steer axle as on the diesel variants operated by EBC for its private hire and rail replacement work.
What is axle load limit?
Axle load limits are being revised for the first time since 1983. Under the new rules, the GVW of a two-axle truck (two wheels in the front axle and four wheels at the back) has been increased to 18.5 tonnes, from the existing 16.2 tonnes.
How do I find my axle weights?
How to Calculate Axle Weight
- Add the total weight of the load you will be carrying to the total trailer weight.
- Divide the total weight of the load and trailer by the total number of tandem axles. Include the load bearing axle in your count.
- Write down the total weight of your tractor or pickup.
What is the mileage of Scania bus?
Scania buses are speed locked to 100kmph and will return about 3.7-4.0 kmpl when driven at 80 kmph.
How much mileage does a Volvo bus give?
The average mileage of the Volvo buses in BMTC is about 2.5-3 kmpl.
Why did Scania leave India?
An internal investigation at Scania into its Indian operations found evidence of misconduct by employees including senior management, the Swedish bus and truck maker said on Wednesday, adding the individuals involved had all left the company.
How can multi-axle vehicle dynamics be improved?
Longer term, autonomous-like vehicles could be used to increase vehicle utilization. In both cases characterizations of multi-axle vehicle dynamics are required. A two-dimensional yaw plane model is used in practice to analyze handling performance of two-axle passenger cars.
How much weight should fall on the steering axles?
• The difference between the right-hand and left-hand wheel loads on an axle must not exceed 3 % of the total axle load. An uneven load will cause the vehicle to lean to one side. • To ensure that the vehicle has good traction, at least 20 % of the vehicle weight must fall on the steered axles.
How are axle weight and bodywork calculated?
Axle weight and bodywork calculations are based on static equilibrium, • The sum of the downward forces is equal to the sum of the upward forces. This means that the sum of the weight of all the truck’s components and its load is as great as the truck’s axle weights.
How are axle load calculations used in transportation?
General information about axle load calcu-lations All types of transportation work using trucks require the truck chassis to be supple-mented by some form of bodywork. The aim of axle load calculations is to optimise the chassis and bodywork location.
