Bike Racks Structural Design

Runva Enterprises Limited | Updated: Oct 31, 2017

Bicycle relative to the car is concerned, is the product extension and supplement. Bike Racks When we were stationed in an outdoor trip, a bike accompanied by a caravan would give us more fun. Especially with the family wandering in the beautiful scenery, see the envy of others eyes, think about the United States.

RV bike frame, sub-front device and rear device, different from the car installed in the roof. Among them, the self-propelled car can only choose after the bracket; trailer car, Bike Racks divided into two kinds of equipment, one mounted in front of the A-beam on the bike frame, the other is installed to the rear of the bike frame.

RV bike frame can usually accommodate two bicycles, Bike Racks through the purchase of accessories alone, can be extended to 3-4 bicycles. But for security reasons, the general installation of two bike frame is enough to use.

Self-propelled car can only be installed to the back, it is noteworthy that the installation position behind the body will be interfered with other equipment. Usually for safety reasons, the bike frame are installed to the rear side of the middle position, if the rear side of the door or ladder, Bike Racks then you can only choose the right side of the installation of the bike frame, if the back without doors and no ladder, then consider Whether there is a window on the back, if there is no window, you can choose to install a long bike frame.

The frame material from the earliest chrome molybdenum steel, Bike Racks evolved to aluminum alloy, and then the use of composite materials such as carbon fiber, there are other scandium alloy, magnesium alloy, titanium alloy, the industry continue to develop new material formula to enhance the pipe and structural design capabilities And innovative processing technology, just to make the frame lighter, Bike Racks stronger, more comfortable and more streamlined and beautiful. Density is one of the key factors determining the weight of the frame, the lower the density, the lighter the frame can be made, the density of the chrome molybdenum steel is 7.9, Bike Racks the aluminum alloy is 2.6-2.9, the titanium 4.5, the titanium alloy 4.3-5.1, Material 1.6, magnesium alloy 1.7, which can be seen chrome molybdenum steel the highest density, the lowest carbon fiber composite. However, in addition to the weight of the frame, but also consider the tensile strength, elasticity coefficient, so although the density is low, Bike Racks but the intensity is not enough not.

The rigidity of the frame is determined by the elastic modulus of the material. The elastic modulus of the steel is 30, the aluminum is 10-11 and the titanium 15-16.5. Bike Racks Therefore, when the diameter and wall thickness are the same, the rigidity of the aluminum frame is only one third of the steel frame First, the rigidity of the titanium frame is only one-half the steel frame. Frame strength is determined by the strength of the material, the strength of the reduction and the quality of the frame pipe, heat treatment process and alloy composition has a great relationship. Aluminum precipitation point only 11-59, titanium 40-120, steel 46-162, Bike Racks compared to aluminum is more fragile and vulnerable. In the actual design, each frame of the pipe diameter will determine the size of the frame stiffness, strength and weight, pipe wall thickness will also affect the frame strength and weight.
