Any kind modifications to the original vehicle can be hazardous. The front fork bicycle system defined in claim 2 said linkage is comprised of pivots and lever arms arranged in a leading link geometry including as part of the linkage one or more shock absorbing units and at least two springs and wherein said at least one shock absorbing unit is a rotary shock absorber and said two springs are each elastomeric springs.

Before starting your build realize that you and you alone are responsible for anything that could happen to yourself and others that you come into contact with.

. O ne must first realize that there is a marked difference between riding solo and sidecar riding. The telescopic Earles fork was a variety of leading link fork where the pivot point was aft of the rear of the front wheel this was the basis of the Earles patent. The leading-link fork fitted to Harley-Davidsons carried the front wheel axle ahead of the spring leg which slid against a coil spring carried in the main fork.

Answer 1 of 3. The advantages of Leading Link you can adjust the trail to lighten the effort required to steer the outfit Floating calipers can be fitted which means braking load is transferred to the main fork tubes so under heavy braking you still have normal suspension travel and only minor dive due to weight transfer and Coil over shocks give adjustability and ensure a smooth rideThe. They were also great Earles fork lead link design whether it be slow or high speed when used on a solo bike such as in the photo of my R69S.

By biker Fri Jan 14 2011 725 pm. The links appear to be independent or formed by a single U-shaped loop around the back of the wheel. The suspension assembly consists of two telescoping struts 1L 1R two stanchions 2L 2R a crown 3 and a steerer tube 4.

I found that all you need is the fork tubes and and swing arm. Other fork designs are girder forks suspended on sprung parallel links and bottom leading link designs. The telescopic Earles fork was a variety of leading link fork where the pivot point was aft of the rear of the front wheel this was the basis of the Earles patent.

See the effect of the fork length on the stress distribution and total deformation a length of 72 was taken in the final design based on the dimensions of the given crate. The most common form of front suspension for a modern motorcycle is the telescopic fork. I just converted my Dnepr to a Ural leading link.

The late Dave Bickers on a leading link Greeves with an aluminum frame. The leading link consist of a tubular or pressed steel structure which connects the steering column in the link pivots and slot in for the suspension struts. We are using CAD construction software.

Adventure Rider - Ride the World. The larger the rake angle the further forward the front. Building a trike is hazardous.

Is the angle measured in degrees of the steering neck from a vertical line. The upper and lower triple clamps are the same - Ural will fit Dnepr Dnepr will fit Ural. Iv seen a lot of homemade forks recently mostly built with square tubeing as the machineing is easier for most home builders.

The Earles fork is a variety of leading link fork where the pivot point is behind the front wheel which is the basis of the Earles patent. You will also need a brake backing plate and anchor link - again interchangeable - Dnepr or Ural will work. Designed by Englishman Ernest Earles this triangulated fork actually caused the front end of a motorcycle to rise when braking hard the reverse of the action of a telescopic fork.

Fixing the length of the fork to 72 inches enables the fork to lift the crate oriented in any direction. Leading Link Fork Our Leading Links are individually made to very small tolerances at a precise welding jig to suit the individual bike. I desided to go with round tubeing and big tubeing at that.

LEADING LINK FRONT END. Essentially Greeves started experimenting with Trailing link forks Like Lambrettas but went to leading link types initially damped with a rubber in torsion cone on the early 1953 - 57 bikes. Lead link forks are also stronger then telescopic less prone to twisting and much better suited for sidecar operation.

4 Designed by Englishman Ernest Earles this triangulated fork actually caused the front end of a motorcycle to rise when braking hard the reverse of the action of a telescopic fork. Patented by Englishman Ernest Earles in 1953 the design is constructed of light tubing with conventional shock absorbers mounted near the front axle. Im going with the leading link design which appears to be a fairly common design amongst trike builders.

Practice is necessary to develop a good and safe sidecar driver. Our leading link kits can be manufactured for use with original fitment wheel brakes and tyres or to suit your own. The Earles fork has a very small wheelbase change under braking or under compression unlike.

With all the hubbub about the new generation of motocross forks there. The word driver is important since one drives a. The typical motorcycle has a pair of fork tubes for the front suspension.

There was a brief period of part Girling Unitsrubber forks then came the first sort of leading link units seen in about late 57early 58. The British Castle fork fitted to the Brough Superior closely followed the Harley. Earles fork on a 1968 BMW R602.

Precision engineering resulting in exactly the trail that is wanted states our complex construction work. STEERING A SIDECAR Leading link forks. Wasp leading link forks also use a floating calliper arrangement reducing front end dive and ensuring stable handling under braking.

A smaller length would give different stress and. The suspension is connected to the bicycle frame Head Tube H. Pros Lighter stiffer can be set up to work as anti-dive less resistance to small bumps stiction Cons Dont look as good to many people Tele forks are a terrible solution with expensive heavy engineering to make up for the inadequacies.

The very best front end design for sidecars and trikes is the leading link design and it has been around forever and have been done in many different styles. The steering of a trike has a few geometry angles which are shown in the above picture.
