Problems solved by technology

[0002] Currently used vehicle transmission systems, such as bicycles, when the pedals are perpendicular to the ground, the torque is zero, and the force on the bicycle wheels is zero. The wheels continue to move forward under the action of inertial force. During the rotation of the pedals, the vertical When it is on the ground, the torque is zero, and when it is parallel to the ground, the torque is the largest. The force on the wheel also changes from zero to maximum, and then from maximum to zero. This continuous reciprocation, when the torque becomes zero, it relies on inertia to advance , so in general, the transmission system of the bicycle is relatively laborious

Embodiment Construction

[0018] Accompanying drawing is a kind of specific embodiment of the present invention. This embodiment comprises housing 2, the shaft fixed on housing 2, the bull gear 7 and pinion 4 on the shaft. The inner arc rack 3 and the outer arc rack 6 are engaged, and the inner and outer arc racks are axially connected as the active mechanism. The two ends of the arc rack are connected to the center of the circle through the radius, and the transmission rod 8 is coaxially fixed on the active mechanism. Such as figure 1 As shown, there are two transmission rods 8, which are fixed on the contact rod 1, and the contact rod 1 is composed of opposite fixed rods fixed on the same shaft. There are three fixed rods, any two of which move with the movable shaft in opposite directions. The one-way gears are equal in size, the radius of the inner curved rack and the outer rack are the same, and both of them are engaged with the outer one-way gear.

Abstract

The invention discloses a transmission device, in particular to a transmission device which comprises a shell, a shaft fixed on the shell and gears positioned on the shaft. The transmission device is characterized in that the gears are one-way gears, turning directions of the two gears are opposite, the two gears are respectively meshed with inner arc racks and outer arc racks, a driving mechanism is formed by axially connecting the inner arc racks and the outer arc racks, and both ends of the arc racks are connected with a circle center through semidiameters; and a driving lever is coaxially fixed on the driving mechanism. The invention has the advantages that two directions of fixed driving lever are opposite, thereby according with a movement principle of pedals of a bicycle; and in addition, zero moment situation is avoided under the condition that the racks are meshed with the gears, thereby having more power and higher efficiency under the situation of equal force.

Description

(1) Technical field [0001] The invention relates to a power device, in particular to a transmission device. (2) Background technology [0002] Currently used vehicle transmission systems, such as bicycles, when the pedals are perpendicular to the ground, the torque is zero, the force on the bicycle wheels is zero, and the wheels continue to move forward under the action of inertial force. During the rotation of the pedals, the vertical When it is on the ground, the torque is zero, and when it is parallel to the ground, the torque is the largest, and the force on the wheel changes from zero to maximum, and then from maximum to zero. This continuous reciprocation, when the torque becomes zero, it relies on inertia to advance , so in general, the transmission system of the bicycle is relatively laborious. (3) Contents of the invention [0003] In order to make up for the deficiencies of the prior art, the invention provides a labor-saving and high-efficiency transmission dev...
