In the specific work process of the wrinkle chain automatic speed governor of the present embodiment in its natural state, governor gear is in balance
State, driving chain elongate the balance of flexible connector, formation office
Portion's bulge-structure, when work, driving gear drives driven gear to rotate by driving chain, during rotation, with driven
The load of gear changes, and governor gear shifts, while driving chain extends, and realizes the automatic speed regulation to driven gear；?
In transmission process, the load resistance of driven gear makes driving chain in driven gear two sides unbalance stress, causes side slack list
Side pilled-in selvedge, in speed regulation process, the flexible edge slack that can effectively adjust driving chain of flexible connector.
In specific working mode, when vehicle on level road when driving, driven gear resistant load is small, driving chain
Stress is small, so that driving chain is not enough to pull governor gear, at this point, the chain unit of driving chain slack list is in flexible connector
Lower tension is acted on, so that driving chain and driven gear cooperate, driven gear, the linear velocity of driving gear are consistent at this time, i.e. N
It is dynamic: N resistance=1:1；
When vehicle is in upper heavy uphill, driven gear resistant load is big, and transmission chain pilled-in selvedge stress is big, so that pilled-in selvedge side
Flexible connector stretch, governor gear is pulled down into shifting, and then slack list chain, which fluffs, speeds, but in slack list side flexible connector
Under effect, slack list chain is caused to tense, so that P of chain unit and the P+Q pin shaft and driven gear are ratcheting, participates in passing
Graduating power.With rotation, when slack list side chain unit, which is detached from driven gear, is moved to driving chain pilled-in selvedge, in governor gear
Pulling force under, corrugated chain unit is straightened again so that driving gear ratio driven gear linear velocity double, i.e.,
N is dynamic: N resistance=2:1, chain pulls down governor gear again at this time, smaller to gear impact force in the accelerator of gradual power,
According to P=FV, tractive force becomes larger, so vehicle grade climbing performance becomes strong at this time, also effectively prevent motor overload and burns.
In the present embodiment, the wrinkle chain automatic speed governor proposed, driving gear, driven gear, governor gear are in triangle
Shape arrangement, while governor gear passes through elastic suspension spring and is fixedly connected with mounting rack, driving chain, which successively bypasses, drives gear, driven

Cross flexible connector connection.By the wrinkle chain automatic speed governor of above-mentioned optimization design, reasonable in design, mechanical structure is simple,
The flexible composition automatic speed-changing system of swing and driving chain of the governor gear under the drive of elastic suspension spring, so that load variation
When driving chain and driven gear according to chain stress automatically adjust linear velocity, realize automatic gear shifting speed changing, to greatly reduce
Running resistance, while engine is realized and is protected, long service life.
In a specific embodiment, driving chain 5 is connected in sequence by N number of chain unit head and the tail, N >=2, so that transmission
Chain integrally has stretching structure, and edge slack is self-regulated at any time in transmission process.
In the specific design method of chain unit, M=4 and Q=3, i.e., each chain unit include four pin shafts and four
A chain piece, flexible connector connect two pin shafts of head and the tail of the chain unit, four pin shafts of each chain unit, in elastic connection
The lower flexible stabilization of part effect.
Referring to Fig. 3 and 4, in other specific embodiments, the flexible connector 53 of N number of chain unit is sequentially connected end to end
Elastic ring is formed, elastic ring successively bypasses at least one pin shaft 51 of each chain unit, realizes multiple chains by elastic ring
The integral telescopic of unit is adjusted.
In elastic ring specifically around in mode, elastic ring successively bypasses first and the 4th pin of each chain unit
Axis 51.
In order to enable flexible connector does not impact chain with engaging for gear, in a specific embodiment, each
Pin shaft 51 includes gear cooperation section and flexible adjustment section, and elastic ring bypasses the flexible adjustment section.
Referring to Fig. 5, in another embodiment specific implementation mode, torsional spring is can be used in flexible connector 53, passes through flexible connector
