Motorcycle and steering structure thereof

Abstract

The invention provides a motorcycle steering structure. A steering handle assembly drags a traction part to act, a traction connecting rod drags wheels to steer, a first steering joint supports up-and-down jumping of the wheels through a first longitudinal rotating shaft assembly, and a first transverse rotating shaft assembly supports steering of the wheels; a second steering joint is provided with a second longitudinal rotating shaft assembly which is matched with the first longitudinal rotating shaft assembly in a supporting mode, the two ends of the traction connecting rod are rotationallysupported when the wheels jump up and down, and the first steering joint and the second steering joint can independently adjust the up-down jump and the steering angle of the wheels by arranging theindependent transverse rotating shaft assembly and the independent longitudinal rotating shaft assembly. Therefore, the up-and-down jumping angles of the wheels of the ATV and the inverted motor tricycle are independently adjusted, the up-and-down jumping height of the wheels can be increased, and entertainment and trafficability are improved. The invention further provides a motorcycle.

Description

technical field [0001] The invention relates to the technical field of motorcycles, more specifically, to a motorcycle and its steering structure. Background technique [0002] ATV beach motorcycles and inverted three-wheeled motorcycles all have two symmetrically arranged front wheels. The kinematic joints of their existing steering structures are ball pins, but the swing angle of the ball pins is limited, and the maximum is 68°, which limits the ability of the wheels to jump. Maximum travel, lack of entertainment and passability. [0003] At the same time, the existing vehicle steering structure cannot achieve front wheel steering, and the inner and outer wheels turn at different angles when turning, that is, the turning angle of the inner wheel is the same as that of the outer wheel when turning. Wears out quickly and causes rough cornering. [0004] Therefore, how to optimize the steering structure of the double front wheel motorcycle is a problem to be solved urgently...
