Spend, the amplitude moved at the top of left side bar 18 is less than the mobile amplitude in 18 bottom of left side bar), bar 18 top in left side drives again laterally puts down
The back upper place for 17 left end of the bar double-wheel scooter backward that weighs is mobile, and then lateral balance lever 17 is branch with itself and 20 junction of middle part bar
Point drive 17 right end of lateral balance lever does the movement of opposite direction (front lower place of rear double-wheel scooter), while lateral balance lever 17
Right end drives the movement for doing opposite direction (front lower place of rear double-wheel scooter) at the top of right-hand rod 19 together, at this time because of right-hand rod 19
Top generates the power of forward downward to 19 bottom of right-hand rod, and simultaneously to the lower balance mechanism connecting rod 16 on the right side of Rear frame, pendulum
Arm 1 and right wheel generate the power of forward downward together, i.e., because left wheel lifts so that right wheel is mentioned with certain downward pressure
Stability of the high right wheel in rear double-wheel scooter driving process.In aforementioned process, lateral balance lever 17 is simultaneously in drive
Portion's bar 20 do it is mobile upwards (or rearwardly and upwardly), 20 bottom of middle part bar by lower damping connecting rod 13 drive damping with
The damping and upper 7 junction of damping connecting rod are that fulcrum does rotation upwards (or rearwardly and upwardly), are sent out by damping
Shock-absorbing function is waved, the vertical tremor and/or lateral tilting of damping connecting rod 7 and rear double-wheel scooter pedal are further decreased
Tiltedly.After left wheel leaves barrier, left wheel is (while there are also left side bar 18 and lateral balance lever with the help of damping
17) restore that (i.e. it is in a vertical state be in horizontality, left side bar 18 for lateral balance lever 17, left wheel and the right side to initial position
Wheel is on same level ground), rear double-wheel scooter pedal not run-off the straight at this time.
When the wheel of left and right two encounters barrier (barrier can be same height or different height) simultaneously, above-mentioned two
A process occurs simultaneously, two wheels simultaneously drive left side bar 18 and right-hand rod 19 move rearwardly and upwardly (move rearwardly and upwardly away from
From may it is identical may also be different) when, left side bar 18 and right-hand rod 19 drive middle part bar 20 to do by lateral balance lever 17 after on
Fang Xiangying is mobile, and then drives 9 bottom of telescopic rod to move up (i.e. telescopic rod 9 is compressed) by middle part bar 20, pair on telescopic rod 9
Defining flange 10 is answered to compress spring 11, spring 11 reduces the shake by damping connecting rod 7 in two wheel brings
Dynamic amplitude, that is, realize the purpose for reducing pedal vibration amplitude, and damping plays the purpose of damping.
In the driving process of rear double-wheel scooter, when needing pedal run-off the straight (such as need in the process of moving
When turning, especially flipper turn, bicyclist is influenced to tilt to pedal side by centripetal force, and pedal is needed to do phase Tongfang at this time
Tilted to respective angles, bicyclist can be made to keep balance, prevent from overturning from pedal, it is ensured that bicyclist's personal safety), it puts down
Weighing apparatus mechanism can help that pedal is more convenient, safer, more labor-saving ground run-off the straight (i.e. adjustment tilt angle), i.e. bicyclist's utilization
Self gravity is applied to the pressure on pedal, and the pressure being especially consequently exerted at left and right sides of pedal passes through the lever of balance mechanism
Pressure result is amplified to two wheels by effect, so that the more convenient promptly transformation height of two wheels and corresponding swing arm inclination angle
Degree, and then achieve the purpose that adjust pedal tilt angle, that is to say, that as long as bicyclist uses a lesser pressure, it will be able to
It is easily adjusted two wheel height and corresponding swing arm tilt angle, and then adjusts pedal inclined direction and angle, utilizes lever
Effect reaches labour-saving purpose, can satisfy the demand that the lighter bicyclist that is self-possessed adjusts pedal inclined direction and angle, specifically
It operates as follows:
When bicyclist is needed in ride to right front flipper turn, bicyclist is influenced entire people by centripetal force
