Full of futuristic feelings Volvo Trucks "black technology"
When it comes to "trucks", it is always easy to relate to words like "clumsy" and "bulky", and Volvo Trucks is obviously an exception. From autopilot to 3D printing, Volvo Trucks has fun with all sorts of "black technology", showing the countless possibilities and technological sense of the truck.
Self-driving truck fleet travels across Europe
In March 2016, the Volvo Truck Auto Racing Team participated in the European Truck Platooning Challenge trial, which is actually intended to look ahead to the future of self-driving truck fleets in Europe. Three Volvo trucks were synchronized via WiFi connection from Gothenburg, Sweden. Denmark, Germany and Belgium eventually arrived in Rotterdam, the Netherlands. The driver of the lead vehicle set the speed and path, and the other trucks automatically followed – effectively increasing the fuel saving capacity by 25%. Reduce emissions and improve transportation efficiency. For this achievement, Volvo Trucks aims to bring more contributions to customers and society.
Volvo Trucks is the world's first truck brand to conduct deep mine operations tests. In June last year, in an underground mine below 1320 meters above sea level, a specially configured Volvo FMX truck was tested for the first time at the Kristineberg mine in Sweden.
The radar is installed in front of the truck's cab and can scan obstacles within approximately 1,000 feet in front of it. In addition, Volvo FMX self-driving trucks are equipped with a total of six sensors, including GPS, laser and radar sensors, which collect a large number of data points and draw a 3D map for the surrounding environment. They are a concentrated expression of technologies such as cameras, computing resources and electrical construction. They can continuously monitor the surrounding conditions of trucks and prevent trucks from hitting other objects. During the FMX self-driving truck, the on-board transportation system continuously collects data to optimize and coordinate the truck's driving route and fuel consumption so that it can adapt to complex road conditions quickly.
In order to fully demonstrate the safety of self-driving trucks, Torbjärn Holmström, a member of the Volvo Group's executive committee and chief technology officer of the Volvo Group, stands without hesitation in the middle of the lane where the truck moves.
“No matter what kind of vehicle we develop, safety is always our biggest concern, and autopilot trucks are no exception. Although autopilot trucks are still only in the concept car stage, Volvo has started to work in real operating conditions. It is testing. Self-driving trucks represent a major advancement in the mining industry and will affect more industries in the future,†said Torbjørn Holmström.
In addition to automatic driving, continuous reduction in fuel consumption is a key area for the improvement of various truck brands. The new concept car developed by Volvo Trucks last year reduced fuel consumption by at least 30% at one time.
The concept car is the result of a five-year research project. There are two secrets behind its excellent fuel-saving performance: aerodynamic design and lower vehicle weight. Aerodynamically, in order to maximize aerodynamic performance, the concept car uses a camera instead of a rear-view mirror, while an aerodynamic deflector lengthens the trailer and weakens the air resistance, while the optimized chassis side apron Covers the rear wheels of the tractor and all the wheels of the trailer. In terms of vehicle weight, the weight of the trailer is two tons lighter than that of the reference trailer, which reduces fuel consumption and increases effective loading capacity.
Although the concept car will not be listed as part of the research project, some of its aerodynamic performance technologies have already been applied to Volvo Trucks' mass-produced vehicles, and Volvo Trucks will likely adopt more solutions derived from concept cars in the future.
“We have spared no efforts to develop more energy-efficient vehicles. This is an area that is highly regarded, not only related to environmental issues, but also closely related to the starting point of reducing the cost of operating our customers. We are proud to drive this development. Our Concept Truck Demonstrating the power of technology to continuously expand and update,†said Claes Nilsson, President and CEO of Volvo Trucks.
Among all black technologies, the most popular is 3D printing. Volvo Trucks, which has kept ahead with the spirit of advancing with the times, has also brought 3D printing technology into the production process, resulting in a significant increase in efficiency.
In March last year, Volvo Trucks incorporated 3D printing technology into its engine production process in Lyon, France. They used Stratasys' Stratasys Fortus 3D printing system and replaced the original metal manufacturing with the thermoplastic material ABSplus. The time for Volvo Trucks to design and manufacture a variety of tools was reduced from 36 days to 2 days, and the production cycle of manufacturing tools for its key pipelines has also been reduced by more than 94%.
More critical is the substantial reduction in production costs. Pierre Jenny, manufacturing director at Volvo Trucks, revealed that 3D printing saves the cost of customization or small-scale mold making. In the past, the cost of 100 euros per cubic centimeter has dropped to an incredible 1 Euro per cubic centimeter.
Since the use of 3D printing technology, Volvo Trucks has used 3D printing to create more than 30 different tools for workers on the production line, including special pliers, brackets, fixtures, etc., and the types are still increasing. For factory operations, ergonomically designed tools are critical.
This is not the first time that Volvo Trucks took advantage of 3D technology. As early as 2014, Volvo Trucks used unique and innovative 3D mapping technology to enable chassis and body design to be carried out simultaneously, which means that the truck body production process will be greatly Reduced, without reducing truck quality. With this technology, Volvo Trucks is able to shorten the truck manufacturing period by up to 14 days.
In addition to the production process and cycle, Volvo Truck's black technology is reflected in all parts of the vehicle, especially the recent hot I-Shift gearbox. I-Shift double-clutch gearbox powers Volvo's powerful new car - the steel rider created a world record of 500m and 1000m static acceleration, while I-Shift with a crawler helped the Volvo FH16 to complete a traction of 750 tons from standstill. Start and travel 100 meters.
The I-Shift dual-clutch gearbox is an excellent example of the improvement and utilization of existing solutions. The dual-clutch gearbox, which was previously only installed on sports cars, is installed on heavy trucks. The advantage of this innovation is that no energy is lost during the shift and the power of the truck is maintained. The I-Shift double-clutch gearbox represents the direction of innovation in the industry and has further improved its technical indicators.
The newly released I-Shift with a crawler can start from a standstill in extreme situations. A suitable rear axle gear ratio optimizes engine speed at high speeds, so it is properly paired with the crawler to reduce vehicle fuel consumption on the highway. For the large transport market, this product can make the transportation work more light, the operation more flexible and accurate, while improving fuel economy, continue to fulfill the goal of bringing high efficiency to customers, and continuously improve Volvo trucks in various segments. Fuel performance, to maintain the leading position of heavy truck efficiency and fuel economy.
Since the first truck was born in 1928, Volvo tirelessly promoted the brand with its forward-looking vision and courage to break through, and it also outlined the exciting future of the truck industry.
