Here’s a quick update to an earlier post on the 2014 Mercedes S-Class body structure.
Here’s a quick update to an earlier post on the 2014 Mercedes S-Class body structure.
Here is a quick look at the Mercedes Benz B-Class F Cell vehicle. Most likely to be found in limited numbers in green states like California. The vehicle consists of a 80-kilowatt fuel cell, 1.4-kilowatt-hour lithium-ion battery pack, and three 10,500 psi hydrogen tanks that fit completely out of sight without impinging on the passenger or cargo space of the petro-powered variant. Those tanks refill in three minutes and hold 3.7 kg (8.2 pounds) of hydrogen.
The front structure is made from aluminium die castings, extrusions and pressings. The passenger compartment is made from steel, including roll-formed boron steel in critical load path areas. The roof panel and all of the closures are aluminium.
The body consists of 50% light alloy in combination with high- and ultra-high strength steels. We have achieved maximum crash safety and outstanding body rigidity for the best noise and vibration comfort.”
Here’s a question for you, do know what “acoustic side windows” really means? If your a regular reader of the blog, you should quickly translate acoustic front windscreen and optional acoustic side windows made with multilayer glass technology to provide great noise insulation to laminated side glass. The image of the 2013 Mercedes-Benz GL below id from the Rescue card for passenger cars. Where’s the battery? How many batteries do you see? See both of them? labeled 1 and 2. Also take note of the suggested cut points. Mercedes-Benz provides extrication cut points that are away from airbag inflators and often are a place on the vehicle where the body structure is weaker.
Guidelines for rescue services are available in various languages as downloadable PDF files. Mercedes-Benz updates the guides below so the information in it is current to assist rescuers during an extrication. Here’s a great company drill or something to read through with your crew.
The 2012 (actually since 2009) Mercedes Benz S-Class is made from a bunch of Ultra High Strength Steel. The B-Pillar and rockers are made from Mega High Strength Steel. Make sure you take a look at the screen shot below from Moditech’s Crash recovery System (CRS) and compare it to the other images. Crash Recovery System would have provided some useful information on scene of a MVA that involved a S-Class.
Mercedes-Benz has a 526 horsepower electric drivetrain in the upcoming SLS AMG E-Cell supercar. Power for the E-Cell will be provided by four electric motors. The E-Cell employs a permanent all-wheel drive system which is powered by a 400-volt battery made up of 12 modules of 72 lithium-ion polymer cells. The battery is housed in within the carbon fiber transmission tunnel, which is structurally integrated into the E-Cell’s aluminum body shell. This is a 2013 model year vehicle expected to hit the roads in the fall of 2012.
The 2013 Mercedes-Benz SL-Class Body Structure, which is predominantly aluminum, plus a few magnesium parts here and there, along with some high-strength steel placed judiciously for a rigid and safe structure. Taking this and other heft-shedding ploys into account, Benz claims a 2013 SL550 will be around 310 pounds lighter than its predecessor.
So what’s under the hood? The engine right? Yes and a little more. The high voltage battery pack on the 2013 Mercedes Benz E400 Hybrid is the battery is behind the front strut tower. In the pictures below, one shows the battery cover and with the battery covered removed. The high voltage orange cables are very close to the right fender. Keep this in mind if you are making an relief cuts for a modified dash lift. The 0.8Kw Li-Ion battery pack operates at 120Vdc.
Below is a unique image of the Reinforced safety cage body structure with over 62% use of High-Strength Low Alloy (HSLA) Steel with ultra high-strength steel in the B-pillars and rocker panels. Make sure you also read below about the airbags, head restraints, and seat belts.
The 2012 Mercedes-Benz M-Class is a rigid uni-body structure that encircles the passenger cabin in a highly protective network of ultra-high and high-strength steel, magnesium reinforcements and triple-layer construction of all eight roof pillars. Advanced crumple zones and subframe-mounting of the axles help to divert impact forces away from the passenger compartment.
Advanced body structure: The uni-body construction of the R-Class uses advanced technology and robust materials to create a virtual fortress for the vehicles’ passengers. High Strength/Low Alloy steel is used in strategic areas and accounts for more than 60% of the body structure. Roof pillars employ three layers of steel, and doors feature steel crossbeams. Full-width front and rear crossmembers, along with a reinforced floorpan and door sills, combine to provide protection in a variety of impacts. Advanced front and rear crumple zones progressively deform to help absorb the energy of an impact, while underhood components are staggered to help prevent them from stacking up in a frontal impact, thereby reducing the likelihood of intrusion into the cabin. An ellipsoidal front bulkhead helps channel some of the forces of a frontal impact under, over and around the passenger cabin.
12-way air bag protection
An advanced system of 8 air bags offers 12-way occupant protection. Dual two-stage front air bags, front and 2nd-row side-impact air bags, and window curtain air bags for all three seating rows are standard.
The uni-body construction of the GL-Class SUV uses advanced technology and robust materials to create a virtual fortress for the vehicles’ passengers. High- Strength/Low-Alloy steel is used in important areas of the vehicle. Roof pillars employ three layers of steel, and doors feature steel crossbeams. Full-width front and rear crossmembers, along with a reinforced floorpan and door sills, combine to provide protection in a variety of impacts. Advanced front and rear crumple zones progressively deform to help absorb the energy of an impact, while underhood components are staggered to help prevent them from stacking up in a frontal impact, thereby reducing the likelihood of intrusion into the cabin. An ellipsoidal front bulkhead helps channel some of the forces of a frontal impact under, over and around the passenger cabin.
There are 9 air bags that offer 13-ways of occupant protection. Dual two-stage front air bags, front and 2nd-row side-impact air bags, a driver’s knee air bag, and window curtain air bags for all three seating rows are standard.
If you clicked the title of this post and were expecting pictures of Mercedes Benz cars blown to pieces than accept my sincere apologizes. An exploded view is a diagram, picture or technical drawing of an object, that shows the relationship or order of assembly of various parts. Below are several “exploded” pictures of with the sheet metal removed.
Leave to German engineering to add features like PRE-SAFE that can detect instability suggesting that a collision or rollover is imminent. PRE‑SAFE can then tighten the front seat belts, adjust the front passenger seat, and close the windows and sunroof. Part of the PRE-SAFE system are radar-based sensors that can detect an impending collision with a vehicle ahead of the E‑Class. PRE‑SAFE Brake then automatically applies up to 100% of the car’s braking force to help reduce the severity of impact.
With 78% of its body panels made from high-strength steel, the body structure of the new E-Class Wagon is even more rigid than its renowned predecessors. The advanced front crumple zone has been refined with thousands of computer-simulated collisions and countless crash tests. An innovative front bulkhead and deformation zones that act on four independent levels to help divert the energy of a frontal impact under, over and around the passenger cabin. The rear crumple zone includes specific design features for the wagon body style, including a high-strength steel floor and spare-tire well with an additional metal shell, diagonal reinforcements beneath the floor, and box-section longitudinal members. The fuel tank is located forward of the rear crumple zone.
Airbags: An advanced system of 9 air bags offers 11-way occupant protection. Dual two-stage front air bags, front side-impact air bags, front pelvic air bags, a driver’s knee air bag, and window curtain air bags for both seating rows are standard. Rear side-impact air bags are optional.
Most of know all the names for the new steel used in the body structures of vehicle. Well, I’ll add one to the list, Mega high Strength Steel (MHSS). Leave up to the safety kings of vehicle, Mercedes Benz to add this material to the list. However, it makes sense in the 2011 MB CL Class Coupe because there are no visible B-pillars. Mercedes Benz states that thru ”Extensive use of ultra-high and high-strength steel in critical areas helps it manage both weight and impact forces. Advanced crumple zones help dissipate impact energy over, under and around the reinforced passenger cabin.” Just because you cannot see the B-Pillar does not mean there is not one. There is a B-Pillar that extends from the window line down to the rocker panel that looks wider than the average B-Pillar. Also note in the image below, you can see the roof rail is made from Mega high Strength Steel (MHSS) and connected to the reinforce rod in the A-Pillar.
The chances of running across a 2011 Mercede-Benz SLS AMG involved in a MVA are slim. But I believe in covering every vehicle, plus it would be a rush to cut up a $200K-$250K car. The body structure is made of 45 percent of the intelligent, weight-optimised aluminium spaceframe is made out of aluminium sections, 31 percent out of aluminium sheet, 20 percent out of aluminium cast and 4 percent out of steel. Maximum occupant safety requires the use of ultra-high-strength, heat-formed steel in the A-pillars. The bodyshell weighs 241 kilograms – an absolute benchmark in the super sports car segment when compared with the peak output of 420 kW/571 hp..
