At the recent Brisbane Truck Show, visitors got to see something new from Kenworth and Volvo, with new models and new features on display. These two brands are the heavy duty sector’s dominant players with well over 35 per cent of the truck sales in that sector between them. The show was a chance to see what keeps these brands at the top and what we can expect from them in the future.
Something New From Kenworth and DAF
It is looking like being another big year for Kenworth and DAF, with two new models, the T410 and T360 on the conventional side and assembling more DAF trucks in the Bayswater plant.
“Feedback from customers with prototype T360 and T410 models has been extremely positive,” said Brad May, Paccar Director of Sales and Marketing. “Of paramount importance in delivering a new range is the need to maintain the exceptional performance, quality, durability and productivity for which Kenworth is renowned. In combination with in-house design validation, the data and information gained from the real-world testing with customers in the Australian environment has delivered these outstanding new products.”
The new models, being seen at the show for the first time for many, feature a wide range of important enhancements, from improvements in visibility, application flexibility through shorter bumper-to-back-of-cab length, better performance and driveability. New exterior and interior styling, improved safety features and a range of available options, optimise the trucks for any application.
DAF’s CF85.510 was at the forefront of the DAF display, this is the model now being locally assembled in Australia. This now allows DAF to offer higher levels of customisation through local engineering input and local parts sourcing.
Also included in the display were two new DAF Euro-6 truck models, the LF260 12 tonner and the LF290 18 tonner 4×2 cab/chassis models, which were introduced to the Australian market in late 2018, aimed at the local distribution market.
Something New From Volvo
The two stars leading the Volvo Trucks stand were the recently released XXL cabin and a model showing off the dual clutch now being offered as an option on some models in some applications.
To achieve the extra space and create the XXL cabin, Volvo has re-engineered the XL Globetrotter cab, moving the rear wall back 250 mm. Volvo tell us the XXL cab has a bed 130mm longer and 250 mm wider than in a regular Volvo FH, providing extra space to stretch out.
The bigger size bed also has a new innerspring mattress with a pillow on top of every spring unit and an adjustable reclining section that adapts to the shape of your body. There’s also the option to equip the cab with a second upper bunk.
Volvo claim that by having two clutches in a gearbox most gear changes made can be power-shifts and there is no interruption of power as the change is made. Essentially this should make the driveline more efficient, but it can also reduce the number of times the driveline is interrupted during ratio changes.
The I-Shift Dual Clutch transmission consists of two input shafts and a dual clutch, which means that two gears can be selected at the same time. It is the clutch that determines which of the gears is currently active. I-Shift Dual Clutch is based on I-Shift, but the front half of the gearbox has been redesigned with entirely new components.
Essentially, the I-Shift Dual Clutch is two gearboxes linked together. During gear changing, the first gearbox is disconnected at the same instant as the second gearbox is connected, so gear changes take place without any interruption in power delivery.
The two clutches are connected to two different input shafts, operating independently of each other. Since the gearbox has 12 gears, one shaft holds the six odd numbered gears, while the other holds the six even numbered gears. The gear changes using the two clutches can be used for all single step gear changes apart form the one between sixth and seventh gear, as this involves a range change from low to high range, or vice versa.
When the transmission control unit decides it is a good idea to skip ratios, when the load is light and the going easy, either going up or down the box, the I-shift will change gears as it would normally without a second clutch.
