Abstract
An All-Terrain Vehicle with a frame, a rear axle and at least a rear trailing arm. The rear trailing arm may attach to the vehicle frame frontward of the rear axle and may enter a wheel hub space partially frontwards of the rear axle and attach to an inset wheel hub. The rear trailing arm may have multiple tubular portions including a frame tubular portion and a wheel tubular portion. The frame tubular portion and wheel tubular portion are attached together at approximately 90 degrees. The wheel tubular portion has at least a distal portion that is configurated to encompass at least a partial length of an ATV axle and a proximal portion that is frontwards of ATV axle. The trailing arm provides clearance when the wheel hub is moved vertically by an angle of 27 degrees.
Claims7
A vehicle comprising:
- a frame;
- a first rear trailing arm;
- a rear wheel with a wheel hub space and a wheel hub, wherein the wheel hub is inset to the rear wheel inside of the wheel hub space, wherein the wheel hub has a wheel hub center axis;
- wherein the first rear trailing arm has a frame tube portion having a frame tube portion proximal end and a frame tube portion distal end wherein the frame tube portion distal end is configured to be attached to at least a portion of the frame frontward of the wheel hub center axis;
- wherein the first rear trailing arm has a wheel tube portion angled from the frame tube portion and the wheel tube portion having a wheel tube proximal portion and a wheel tube distal portion, wherein the wheel tube proximal portion is frontward of the wheel hub axis;
- and
- wherein the wheel tube distal portion is attached to the wheel hub and the wheel tube distal portion has a lumen that surrounds the wheel axis.
A trailing arm for a vehicle comprising:
- a frame tube portion and a wheel tube portion that is angled from frame tube portion;
- wherein the wheel tube portion has a wheel tube proximal portion and a wheel tube distal portion;
- wherein the wheel tube proximal portion has a circumference less than the wheel tube distal portion circumference;
- and
- wherein the wheel tube distal portion has a wall thickness defining a lumen.
A method of manufacturing a trailing arm:
- obtain a tubular wheel portion for a trailing arm;
- obtain a tubular frame portion for a trailing arm;
- remove a portion of tubular wheel portion to define a tubular wheel distal portion and a tubular wheel proximal portion wherein the tubular wheel proximal portion is a remaining amount from the removed portion;
- and
- attach the tubular wheel portion distal portion and tubular frame portion together.
