Description

Tricycle

The present invention relates to a kind of tricycle.

The bicycle of Xiao Shouing is a two-wheel in the market, vehicle seat height, gravity center of human body's height, air resistance is big, two pedals become 180 ° to be fixed on the main shaft, and the transmission dead angle is arranged in the driving process, and the balance in the car operational process is controlled by cyclist's two arms and gravity center of human body.Thereby do not give full play to the function of partes corporis humani position.

The objective of the invention is to overcome existing bicycle weak point and the design-calculated vehicle seat is low, the gravity center of human body is low, two pedal rods and two hand lever swings, and the government office in feudal China at no transmission dead angle is controlled the tricycle of turning of bicycle mechanism by people's shoulder.

The objective of the invention is to realize by following design plan, vehicle frame (9) middle part is vehicle seat (7), there are two drive wheels (11) in the place ahead of vehicle frame, there is a wheel flutter (10) at the vehicle frame rear, two drive wheels are contained in two semiaxis (6,47) on the main shaft of suit, the vehicle frame forefront is variable shaft (5), the variable shaft below is tension wheel (13), the upper right side dress pin axle (3) of main wheel, pedal rod (4) is contained on the pin axle, and the right-hand of pin axle is hand axle (1), and hand lever (2) is contained on the hand axle, dress steering hardware (8) in top behind the vehicle frame, brake system is controlled (12) by brake control.The human pedal pulls, and the operation of the strength of waist driving car, and both feet, both hands can be exerted oneself simultaneously, also can replace or exert oneself separately.Propulsive effort on hand axle (1) and the pin axle (3) is passed to variable shaft (5) by chain, gear (50) engagement on big gear wheel on the variable shaft (57) and the main shaft, drive two drive wheels (11) traveling, the speed changeization of the speed of a motor vehicle is by becoming control (15) control variable shaft (5), the braking of car, (12) control, affect movable jaw (117) to stretch out by brake control simultaneously, pedal rod (4) is blocked.

Advantage of the present invention is that vehicle seat is low, and the gravity center of human body is low, and air resistance is little, the speed of a motor vehicle is high, three wheels safety that operates steadily is sitting posture by bike, and bipod leg and two arms can be exerted oneself simultaneously, also can replace or exert oneself separately, shoulder control car turns to, and makes each position of human body be in the best state of exerting oneself.Hand lever, pedal rod are swung when driving car, so no transmission dead angle makes people's power efficiency height.
