BMW Motorrad has always been an industry leader in the research and development of vehicle performance and controllability. As for personal safety, which is most important to motorcycle riders, BMW Motorrad also treats it with high standards. The recently leaked patent drawings show the crumple zone design applied to motorcycles for the first time. Several seemingly simple but ingenious structures will be of great help to the safety of riders.
The crumple zone design derived from automobiles will be applied to motorcycles for the first time.
01 Patented parts create a motorcycle crumple zone
When a car collides, the impact is absorbed through the design of the crumple zone and prevents damaged parts from being squeezed back and injuring passengers again. , and the patent applied for by BMW Motorrad this time uses the same approach, using the V-shaped part numbered 22 in the picture to prevent the impacted front wheel, front fork and other parts from compressing the rider and damaging the engine after the impact, and also Absorbs kinetic energy from impact to improve driver safety.
According to patent picture 1, you can see that the motorcycle is about to collide with the wall on the right.
The English letter d area on the patent picture 2 is the impact area. The impact may push the front wheel, front fork and other parts towards the engine. In addition to the possibility of injuring the driver, the engine will also be damaged. damage.
As can be seen from the patent figure 3, when the front fork and tire move backward after impact, part 22 and the rear area can prevent the impact from moving backward.
The crushing device added behind the front wheel will not affect the normal movement of the front wheel.
In the event of an impact, the tires, wheel frames and other parts will be restricted within the No. 22 part, and the rear parts will be used for buffering.
02 Passive safety equipment that keeps pace with the times
In addition to advanced ABS anti-lock braking system, TSC tracking system, driving mode and other active safety equipment, modern motorcycles also have passive safety equipment. Safety equipment such as airbag anti-fall clothing and SRS airbags for motorcycles are also available. I believe that in a few years, the fatality rate of motorcycle accidents will be significantly reduced.
In the past, BMW and ALPINESTARS *** jointly developed airbag safety personal parts.
The SRS airbag equipped by HONDA GOLDWING is the best example of motorcycle passive safety technology.
