Suspension arm assembly for a vehicle, and vehicle incorporating same

A multi-use vehicle, comprising:

• a vehicle body frame;
• a suspension arm assembly connected to the vehicle body frame;
• a shock absorber disposed between said vehicle body frame and said suspension arm assembly;
• and
• a knuckle connected with said suspension arm assembly;
• wherein the suspension arm assembly comprises:
• a pivot pipe pivotally attached to the vehicle body frame;
• and
• a pair of pipes extending in a lateral direction of the vehicle body frame, the pair of pipes comprising proximal end portions connected to the pivot pipe and spaced apart from each other in the front-rear direction of the vehicle body, and distal end portions arranged proximate one another, and extended toward an exterior of the vehicle body so as to form a substantially triangular profile;
• said distal end portions disposed external to the vehicle body frame;
• a joint member attached to the distal end portions of the pair of pipes, said joint member comprising a plate portion and a boss portion attached to said knuckle;
• and
• a substantially U-shaped band arranged at the distal end portions of the pair of pipes such that an open concave surface of the U-shaped band faces outwardly of the vehicle body;
• wherein the distal end portions of the pipes are connected to a convex surface of the U-shaped band;
• and wherein the plate portion of the joint member is attached to the pair of pipes so as to cover the U-shaped band from an upper or lower portion thereof.

A double wishbone-type suspension system for a vehicle having a body frame, said suspension system comprising

• a knuckle;
• a pivot pipe pivotally attached to the body frame;
• a pair of pipes arranged in a longitudinal direction of the vehicle,
• the pair of pipes having
• proximal end portions spaced apart from each other, and connected to the pivot pipe, and
• distal end portions arranged proximate one another, and extended outwardly so as to form a substantially triangular profile;
• said distal end portions defining distal end portions of the pipes;
• a joint member attached to the distal end portions of the pipes, said joint member comprising a plate portion, and a boss portion attached to said knuckle;
• and
• a substantially U-shaped band arranged at the distal end portions of the pipes such that an open concave surface of the U-shaped band is situated facing outwardly;
• wherein
• the distal end portions of the pair of pipes are connected to a convex surface of the U-shaped band;
• and
• the plate portion of the joint member is attached to the pair of pipes so as to cover the U-shaped band from one of an upper and lower portions thereof.
