Introduktion

Fahrrad-Auflieger mit Regen-Deckblatt


Ich habe mich entscheiden, einen Fahrrad-Auflieger für persönliche Benutzung bauen. Weil ich in Arcata wohnen, finde ich es einfach und amüsant überall fahren, außer wann ich muss Sachen bewegen, die in meinen Rucksack nicht passen. Also, ein Fahrrad-Ausflieger würde die logische Lösung meines Problem. Es wird mir erlauben, selbstbewusst zu sein. Ein Regen-Deckblatt wird ins Design für Behandlung durch schlechtes Wetter einbeziehen, weil es hier ganz oft regnet.

Projekt Anforderungen

Kriterium

  • Cost (less than 50 dollars)
  • Weight (Weight=8)
  • Simplicity (easier to assemble the better. Most inportantly, the easier to attach and take off the better)(Weight=8)
  • Durability of the material (more rain proof the better) (Weight=7)
  • Amount of movable parts (the less the better) (Weight=3)
  • Availability of material locally (closer to Arcata the better) (Weight=5)


Zeitplanvorschlag

March 13, 09 : Final project design completed March 15, 09 : Finished buying all materials March 22, 09 : Finished building the trailer, assembling all parts and attaching it to the bicycle March 30, 09 : Finished all trouble shooting, final product complete April 16, 09 : Finished writing the final report and complete the website


Design

An Instep baby jogger/stroller was found at the Arcata Angles of Hope thrift store. It was purchased for $ 20.00. The stroller was disassembled and a bicycle trailer was constructed from the parts.


The tongue of the trailer:

Figure 1: "Tongue" of the trailer

The front portion of the stroller originally holding the front wheel was converted into the front portion of the trailer “tongue” that hooks onto the rear bike rack (figure 1).

Figure 2: Bolt to attach the trailer to the rear bike rack

I took the front wheel bracket and installed a 6inch by 5/8ths inch bolt to it. Washers were used to hold the bolt in place. Then a 1 1/4th inch chain was slipped onto the bolt and help in place by 4 washers and 2 nuts. So there are 6 total washers, to brace the towing chain. 4 nuts total were used (Figure 2).

Then a safety chain was added from the shaft of the bolt to the brace of the frame (figure 1). The chain is held in place by a bolt screwed through the brace. Rubber washers were placed between the brace and the chain, and then a washer and then a nut were added to secure it in place (figure 1).


Figure 3: Trailer with rain fly off


The frame leading form the rear axel to the tongue was already attached, To turn it into the trailer, it was flipped upside-down with the wheels remaining attached. Then a supporting “L” shaped beam was a added to fix the position of the tongue and frame (Figure 3). First holes were drilled with a high speed drill bit (1/4 inch).


Then a screw was inserted into the hole to hold it together. Rubber washers were placed between the screw head and the metal frame, and on the other side, between the metal frame and the nut holding the screw on.

The basket was attached to the frame via three u brackets, 1 in the front and two in the rear, and two hook support screws, one on either side (Figure 3).

Figure 5: Fly attached with velcro

The rain fly from the jogger was taken and attached to the basket with four Velcro straps (Figures 4 and 5).


Kosten

  • Budget
Frame Hardware
$50.00 $25.00

I did not have to spend the entire budget. Only $20.00 was spent on the frame of the trailer. The entire $25.00 dollars was spent on the hardware. Hardware included bolts, nuts, washers and chain.



Schlüsse

Overall, the project was a success. Converting the Instep baby jogger/stroller was strait forward. Only 2 holes needed to be drilled and there was no welding required. It can hold at least 200 pounds applied directly onto the basket area, while the trailer is static. The design criteria were met. The trailer cost less than $ 50.00 out of pocket. Since the trailer was converted from the jogger, it is inherently light, durable and light. The Jogger was purchased at a local thrift store, so the material was available locally.


One disadvantage for this design is a rear bike rack is required to hitch the trailer onto, and the bike rack itself had to be modified for easy removal of the trailer.

When bicycling uphill pulling a load of 20 lbs, there was a lag between the trailer and the bike. Consequently the trailer pulls back slightly.I found that a simple bungie cord eliminates this problem. Unfortuninatly it cause the trailer to hit the rear tire, which was not previously a problem. Thus, I removed the bungie cord and am still trouble shooting ideas to prevent the lag.

The rain fly was tested by leaving the trailer outside for 12 hours while it was raining. An object was placed in the basket beneath the rain fly. When I checked the object after 12 hours, I found that it was not even damp. Thus, I will have to conclude the rain fly is a sucess.
