Single-rack drive bicycle with reciprocating variable circular motion

Abstract

The invention discloses a single-rack drive bicycle with reciprocating and variable circular motion. device, single rack, reciprocating and changing circumference device, speed change device and reversing device, the reciprocating and changing circumference device converts the reciprocating motion of the rack into a circular motion, the speed change device can realize the high and low speed switching of the circular motion, and the reverse device can realize the A coordinated action like raising the rack can reverse the car. Its characteristics are that the up and down motion of the pedal is converted into the reciprocating motion of the rack, and then converted into a circular motion with high efficiency and low noise through the reciprocating circular device; the gear and the rack can be sealed, which not only reduces oil pollution but also achieves full lubrication; There will be no problem of "dropping the chain"; a single rack is equivalent to the large chainring of a traditional bicycle, which can realize the function of continuously shifting.

Description

technical field [0001] The invention relates to a single-rack transmission bicycle with reciprocating and changing circular motion, more particularly, it relates to the use of racks, gears and other components to change the up and down motion of the pedal into the reciprocating motion of a single rack, and then the rack The reciprocating motion of the bicycle is converted into circular motion, thereby driving the bicycle forward. This is a single rack transmission method that can replace the chain, belt, and shaft transmission. On bicycles, tricycles, or other machinery that uses rack drives. Background technique [0002] Now we can search for many ways of converting circular motion to reciprocating motion, so it is not difficult to realize circular motion. In the process of switching the movement direction of the reciprocating motion, some have the problem of transmission dead point, and some transmission gears and other mechanisms may have teeth or collisions; 2. When the...

Problems solved by technology

[0009] The purpose of the present invention is to solve the problems in the prior art that the chains are easy to fall or even break, and the chains exposed in the air are easy to be dirty and rusted, resulting in transmission loss, etc. To solve technical problems such as low efficiency, provide a transmission scheme that can replace the circular rotation of the chain and pedals in bicycles. It uses a single rack to replace the chain, and replaces the circle of the traditional pedals with the up and down alternate motion of the pedals. Movement, which converts the up and down alternating motion of the pedals into the reciprocating motion of a single rack, and then converts the reciprocating motion of the single rack into circular motion, thereby driving the bicycle forward.
