Chassis of different Heavy Vehicles Companies
SCANIA
Our new Scania city bus chassis is designed
to carry a large number of passengers along demanding urban and
suburban routes.
Scania manufactures two well-proven and highly competitive
city bus chassis: the N chassis for when you want the maximum
number of standing passengers; and the cost-efficient K chassis,
which offers a lower initial cost, excellent fuel economy due to
reduced energy-loss in the powertrain, and easily accessible parts
for service and maintenance.
Available in 10.5 to 15-metre versions (the longer with
hydraulically steered tag axle), this robust and reliable low-floor
chassis offers the following benefits:
A 9-litre engine equipped with Scania EGR
guarantees compliance with Euro 4 or EEV at all times and in
all driving conditions, with excellent fuel economy and without the
use of additives. Available in three outputs from 230 hp
to 310 hp, depending on emission level.
Proven engine and chassis parts based on
Scania’s industry-leading platform of common components for trucks,
coaches and buses. Scania chassis are renowned for their
exceptional durability and dependability and an impressively long
service life – all of which means more hours on the road and lower
operating costs.
High torque from low revs for fantastic
starting power and relaxed performance.
The ergonomically designed driver station
ensures relaxed and efficient driving, even at the end of a long
day. The chassis front is adjustable to ensure the best positioning
of the driver’s area.
The uptime-enhancing features include a CAN-bus
electrical system with more functionality but less wiring and fewer
components.
The fuel-saving features include an
innovative air-processing system that uses excess energy to fill
the air tanks, and an automatic gearbox that achieves higher torque
at low speeds, while enhancing fuel economy.
World-class brake performance – now improved
with an electronic brake system and electronic stability
program.
Exceptionally rigid chassis frames with air
suspension and anti-roll bars for comfort, stability and minimal
vibration.
Adapted for low-floor or low-entrance
applications, the low-floor version being fitted with a
transversely mounted engine.
A choice of 5- or 6-speed automatic gearboxes,
the latter with high torque in the starting position and overdrive
characteristics in the final gear. Both models improve fuel
efficiency.
Plastic low-weight fuel tanks – Scania EGR does
not require urea-based additives and thus needs no additive tank on
the chassis.

VOLVO
The B9TL chassis shared the same design of the B7TL. The key
difference from both its predecessor, the B10TL Super Olympian and
B7TL, is the new 9.4-litre engine originally designed by Renault. The radiator is located at the rear offside,
similar the smaller B7TL. The front module design is shared with
other low-floor bus chassis built by Volvo, and independent
suspension is fitted at the front axle.
The B9TL was initially offered in 3-axle format, and the 2-axle
variant was added in 2006 to replace the B7TL. The driveline
comprises a Volvo D9A Euro III engine (rated at 300bhp or 340bhp), which
was later replaced by the Volvo D9B Euro IV engine (uses selective
catalytic reduction technology; two versions were offered - the
D9B260 rated at 260bhp for 2-axle version, and a higher powered
D9B310, rated at 310bhp, for 3-axle version), and coupled to a
ZF 5/6-speed gearbox. Volvo also
offer the Voith 4-speed gearbox as an
option.
The front wheels of 3-axle B9TL are usually supplied by ALCOA of the USA, but some buses (including the 3
prototypes) have all their wheels supplied by ALCOA.
Singapore
SBS Transit of Singapore placed an order for 150 B9TL chassis, the
largest order to date, which were fitted with bodywork from
ComfortDelgro Engineering,
part of SBS Transit's parent company. These are Singapore's first
wheelchair-accessible buses.
However, instead of automatic ramps, SBS Transit has decided to use
manually-operated ramps. While the ramps would need more time to
deploy, they would be more reliable than automatic ones and would
be cheaper to install and maintain because of the absence of
complicated mechanical parts.
The buses were launched on 15 February 2006 by Singapore's then Minister
for Transport, Yeo Cheow Tong. They were supposed to be
deployed from April onwards, but this was delayed till June 2006 -
they were slightly wider than most other buses in Singapore, bus
stops had to be retrofitted for the wheelchair-bound, and it was
necessary to survey which bus routes in Singapore had the most
pressing need for such buses.
Fourteen such buses were registered initially, in the range of
SBS7300P to SBS7320G (not all registration numbers inclusive). Bus
Service 21 was the first to receive the buses, where ten were put
into service serving between St. Michael's
Bus Terminal and Pasir Ris Interchange on 27 June 2006, with an official launch
ceremony held at Pasir Ris Interchange on 26 June 2006. Service 21 was chosen after
consultations with various welfare organizations serving the needs
of the handicapped, as well as the Land Transport
Authority. This route also passes the premises of the Handicaps
Welfare Association as well as Tan Tock Seng
Hospital, among other medical facilities. B9TLs continued to
roll out of the bodywork assembly plant at SBS Transit's Hougang depot, being deployed on
selected routes served by several Depots, where the routes chosen
are expected to serve large numbers of elderly commuters.
SBS Transit placed an additional order for 50 more chassis soon
after placing its first B9TLs into operation, bringing the total
fleet size to 200. As of 29 September 2006, before the Euro 4 dateline of 1 October 2006 set by the Singapore
government for diesel vehicles, all 200 B9TLs have been registered,
with registration numbers SBS7300P to SBS7499A. Currently, all 200
B9TLs are out on the roads.

The Mercedes-Benz OC 500 LE is a modular,
heavy-duty, twin-axle bus chassis produced by Mercedes-Benz/EvoBus in Sámano, Spain. It was designed as a base for low-entry city,
suburban, and intercity buses weighing a maximum of 18,000 kg. It
has much in common with the chassis used for the Mercedes-Benz Citaro integral bus
range. The engine is horizontally-mounted over the rear
overhang.
Singapore
SMRT Buses are currently taking delivery of
132 Mercedes-Benz OC500LEs for fleet replacement and expansion.
These buses feature bodywork built by Gemilang, engines that meet
Euro 5 emissions standards and are
wheelchair accessible. They are the first buses in South-East Asia
to be fitted with an Euro 5 engine. The first OC500LE began
passenger service at end June 2008. The later production buses
includes some slight modification, such as a bigger side and rear
route number display EDS.

MAN
Build on MAN.
MAN is among the great marques in the international arena of
commercial-vehicle
manufacturing: it is one of the leaders in city bus and touring
coach
construction, and extremely successful as a truck manufacturer
renowned for
its competence and innovative ideas. A marque that conquers markets
– and
successful around the globe. So if you rely on chassis made by MAN
you opt
not only for vast experience and expertise but also for a high
degree of safety
which only a partner as powerful as MAN can offer.
Above all other things, our chassis offer you excellent quality for
first-class
body solutions. Our chassis are body-friendly, reliable and have a
long service
life. They set new standards in terms of comfort, ride dynamics and
road
safety. They are powerful, achieve low consumption values and are
environment-
friendly – and impressively economical with it. In short, ours is a
programme
of almost infinite possibilities for bus and coach bodies and
vehicles
of every type and tonnage. The choice is yours.
Chassis for bodies of all kinds.
The wide range of MAN bus chassis embraces the whole world
of buses. There are chassis for solo vehicles, articulated
buses
and double-deckers – in both the classic and semi-low-floor
design
as well as the pure low-floor version. For coaches you have
a choice ranging from the 2-axle type with front-mounted
engine
to the 15 m 3-axle model with engine at the rear – and
practically
all chassis are available in right-hand and left-hand drive.
Of course, that also applies to club buses, mobile homes or
horse boxes and almost all types of special bodies.
Owing to the great flexibility of the design of MAN chassis
models
almost everything is feasible: engine-gearbox combinations,
axle and suspension variants – everything is there for you to
pick. And there are still many more things.
