Referring to fig. 1-6, a bicycle learning aid includes a suspension 1, and is characterized in that: the quantity of the suspensions 1 is two, one side of the suspension 1 is provided with a circular through hole, a bearing 2 is fixedly sleeved in the circular through hole, a rotating shaft 3 is fixedly sleeved in the bearing 2, centrifugal devices 4 are fixedly installed at two ends of the rotating shaft 3, each centrifugal device 4 comprises a rotary table 41, the rotary table 41 is fixedly connected with one end of the rotating shaft 3, a centrifugal sleeve 42 is fixedly installed at a position, close to the outer surface, of one side of the rotary table 41, a sliding table 43 is installed at the top of the rotary table 41, a sliding hole is formed in the top of the sliding table 43, a sliding rod 44 is movably sleeved in the sliding hole, a seed distributing block 45 is fixedly installed at the top of the sliding rod 44, a spring piece 46 is fixedly installed at the top of the seed distributing block 45, a traction rope 47 is fixedly installed at the bottom of the outer surface of the sliding rod 44, one end of the traction rope 47 is connected with an auxiliary device 7, a shell 5 is fixedly installed at a position, which is positioned outside the centrifugal device 4, on one side of the suspension 1, the internal surface of shell 5 is provided with the ratchet and this ratchet is corresponding with centrifugal device 4, the one end fixed mounting of shell 5 has closing cap 6, one side fixed mounting that circular through-hole and circular through-hole were seted up to one side of closing cap 6 has auxiliary device 7, auxiliary device 7 is including installation piece 71, one side and closing cap 6 fixed connection of installation piece 71, the opposite side fixed mounting of installation piece 71 has adjusting sleeve 72, fixed mounting has stopper 73 on the position that adjusting sleeve 72's inner chamber is close to installation piece 72 one end, one side fixed mounting of stopper 73 has spring 74, the one end fixed mounting of spring 74 has regulation pole 75, the inside of adjusting pole 75 is provided with the cavity, adjust the inside of pole 75 movable sleeve-joint at adjusting sleeve 72, the one end of haulage rope 47 and the one end fixed connection of adjusting pole 75, the other end fixed mounting of adjusting pole 75 has auxiliary wheel 76, the external surface fixed of pivot 3 has cup jointed rear wheel 8.

Wherein, through the fixed connection of the turntable 41 and one end of the rotating shaft 3, when the rotating shaft 3 drives the rear wheel 8 to rotate, the turntable 41 is also driven to rotate, so that the centrifugal device 4 integrally rotates, the centrifugal force generated by the rotation of the centrifugal device 4 can enable the sliding rod 44 to slide in the sliding hole formed at the top of the sliding table 43, at this time, the traction rope 47 is fixedly installed at the bottom of the outer surface of the sliding rod 44, one end of the traction rope 47 is fixedly connected with one end of the adjusting rod 75, so that the adjusting rod 75 retracts towards the inside of the adjusting sleeve 72, so that a height difference is generated between the auxiliary wheel 76 and the rear wheel 8, the auxiliary wheel 76 can not contact with the ground, and a learner can not ride through the support of the auxiliary wheel, so that the learner must balance and ride through self-adjusting the gravity center position, thereby improving the learning progress of the learner, the learning efficiency is improved.

Wherein, one side fixed mounting through stopper 73 has spring 74, the one end fixed mounting of spring 74 has regulation pole 75, make slide bar 44 will make through dragging of haulage rope 47 draw and adjust pole 75 and carry out the displacement and need produce the centrifugal force that is greater than spring 74 elasticity, this makes carousel 41 must have certain rotational speed just can make slide bar 44 have certain centrifugal force, thereby make adjust pole 75 can not take place the displacement under rear wheel 8 is in the state of low speed, thereby make the beginner contact bicycle can carry out the adaptation of riding of low speed through the auxiliary wheel of both sides for the first time, and adjust pole 75 can not take place to retract under the low speed state, thereby the practicality of the device has been improved, simultaneously, accessible spring 74 carries out the shock attenuation when auxiliary wheel 76 contacts with the ground of injustice, thereby the practicality of the device has further been improved.

Wherein, there is spring leaf 46 through the top fixed mounting of the breeding block 45, when making the 8 rotational speeds of rear wheel very fast, make the slide bar 44 make the breeding block 45 contact with the internal surface of the outer casing 5 through the centrifugal force, the internal surface through the outer casing 5 is provided with ratchet and this ratchet this moment, make the breeding block 45 produce great frictional force with the ratchet of the inner surface of the outer casing 5 and slow down, avoid the speed that the beginner rides very fast and appear the bicycle fall down out of control and cause the injured problem, simultaneously, thereby the spring leaf 46 sends great sound to warn with the resilience deformation that can be continuous when contacting with the ratchet of the inner surface of the outer casing 5, thereby timely inform the learner to slow down, the device practicality has been improved.

The cavity is formed in the adjusting rod 75, so that the adjusting rod 75 is lightened in weight, can better move under the centrifugal action of the sliding rod 44, and the running stability of the device is improved.

The using method of the invention is as follows:

during the use, thereby the pivot 3 drives also can drive carousel 41 and rotate when rear wheel 8 rotates and makes centrifugal device 4 wholly rotate, and centrifugal force that centrifugal device 4 rotated produced can make slide bar 44 slide in the slide opening that the sliding stand 43 top was seted up for adjust pole 75 retracts to the inside of adjusting sleeve 72, thereby makes the difference in height produce between auxiliary wheel 76 and the rear wheel 8, makes auxiliary wheel 76 unable and contact with ground.

The centrifugal force greater than the elastic force of the spring 74 is required to generate a centrifugal force for the adjustment lever 75 to be displaced by the pulling of the pulling rope 47 of the sliding lever 44, so that the rotating disc 41 must have a certain rotating speed to enable the sliding lever 44 to have a certain centrifugal force, so that the adjustment lever 75 is not displaced when the rear wheel 8 is in a low speed state, and the spring 74 can be used for damping when the auxiliary wheel 76 is in contact with an uneven ground.

When the rear wheel 8 rotates faster, the sliding rod 44 makes the seed matching block 45 contact with the inner surface of the shell 5 through centrifugal force, the seed matching block 45 generates larger friction force with the ratchet wheel on the inner surface of the shell 5 to decelerate, and the spring piece 46 continuously deforms and rebounds when contacting with the ratchet wheel on the inner surface of the shell 5 to give out larger sound to warn.
