As shown in figs. 9-1 and 9-2, fixed block 9 is cylindrical, central shaft is to having filling block mounting hole 9-1, filling block assembly 10 is arranged in filling block mounting hole 9-1, right buckle mounting hole 9-2 is had in fixed block 9, the retaining screw be arranged in right buckle mounting hole 9-2 is fixedly connected with left fixing column 5-1-2 by attachment hole, and the right fixing column of right buckle 5-2 inserts in right buckle mounting hole 9-2.
As shown in figs. 10-1 and 10-2, filling block assembly 10 comprises the filling block 10-1 of two pieces of docking, and two pieces of filling block 10-1 dock rear center and are provided with through hole 10-2, and pin axle 1 is arranged through through hole 10-2.
The external diameter of pedal driving component 8 and the external diameter of fixed block 9 are all identical with the internal diameter of front-wheel 11 center mounting hole, are all arranged in the center mounting hole of front-wheel 11, and pedal driving component drives front-drive.
Two of clutch component 7 pieces of clutch block 7-1 are wrapped in the outer docking of plectrum 2, put brake spring 7-2, plectrum 2 is positioned at clutch chamber 7-5.The pin axle 1 installing clutch component 7 loads in front-wheel 11 through pedal driving component 8, fixed block 9.Filling block assembly 10 is held pin axle 1 tightly and is contained in fixed block 9.Pin axle 1 is through clutch bounding means 6, and the claw 6-2-2 in clutch bounding means 6 on snap ring 6-2 is enclosed in the locking slot 7-4 on clutch block 7-1.Fixing column 5-1-2 on left buckle 5-1 loads in the left buckle mounting hole 8-3 on pedal driving component 8, and retaining screw is fixed through the fixing column 5-1-2 on right buckle mounting hole 9-2 and left buckle 5-1.Right buckle 5-2 is arranged on fixed block 9.Bayonet lock 4-1-3 on left buckle 4-1 and draw-in groove 6-1-3 blocks.The other end that right jamming button 4-2 penetrates pin axle 1 is close on the face of filling block assembly 10.Left standpipe 3-1 and right standpipe 3-2 penetrates pin axle 1 from pin axle 1 two ends respectively, the card article 4-1-2 of left buckle 4-1 and right jamming button 4-2 lays respectively in the standpipe body 3-1-1 of left standpipe 3-1 and right standpipe 3-2, the standpipe body 3-1-1 of left standpipe 3-1 and right standpipe 3-2 is fixed on perambulator all the time, prevents wheel from rocking.
When pin axle 1 Forced rotation, plectrum 2 on pin axle 1 is followed rotation and is contacted with two pieces of clutch block 7-1 and apply a rotating force to two pieces of clutch block 7-1, locking slot 7-4 is built with claw 6-2-1, clutch block gives claw 6-2-1 rotating force again, because standpipe body 3-1-1 maintains static, card article 4-1-2 is loaded in standpipe body 3-1-1, so left buckle 4-1 maintains static.Bayonet lock 4-1-3 is installed in draw-in groove 6-1-3, therefore the pedestal 6-1 of clutch bounding means 6 is motionless.Snap ring 6-2, compression spring 6-3, the plastic spacer 6-4 ring 6-5 that is locked is pressed on pedestal 6-1, and claw 6-2-1 is fit in the locking slot 7-4 on clutch block 7-1.When rotating force is less than snap ring 6-2 and compression spring 6-3 frictional force is greater than brake spring spring-back force, snap ring 6-2 is motionless, clutch block 7-1 by claw 6-2-1 fixed affect produce both open to both sides along moving of claw 6-2-1 horizontal direction.When clutch block 7-1 is opened to a certain degree, teeth 7-3 on clutch block 7-1 is meshed with the teeth on the clutch action chamber 8-2 sidewall in pedal driving component 8, now clutch block 7-1 cannot open again, and under this state, the power of rotating force in clutch block 7-1 opening direction equals the spring-back force of brake spring.When rotating force slowly increases above snap ring 6-2 and compression spring 6-3 frictional force, snap ring 6-2 can rotate, teeth 7-3 on clutch block 7-1 is meshed with the teeth on the clutch action chamber 8-2 sidewall in pedal driving component 8, front-wheel is subject to rotating force, when rotating force is greater than the frictional force on front-wheel and ground and snap ring 6-2 and compression spring 6-3 frictional force simultaneously, front-drive.When rotating force is clockwise, front-wheel is in the state of conjunction and rotates forward, and when rotating force is counterclockwise, front-wheel is in the state of conjunction and rotates backward.
When pin axle does not stress, clutch block 7-1 holds tightly together by the spring-back force of brake spring 7-2, and the teeth on the clutch action chamber 8-2 sidewall in the teeth 7-3 on clutch block 7-1 and pedal driving component 8 depart from, and clutch component 7 and pedal driving component 8 rotate and be independent of each other.When perambulator is carried out, front-wheel rotates forward or backward by thrust forward or backward, and pin axle 1 is by rotating force, therefore rotates pin axle before and after front-wheel and do not rotate.
