Degree；The bounce of traveling wheel is buffered by the friction between third friction plate and two friction blocks.
In the present invention under the action of the second compressed spring, frictional resistance between the first friction plate and the second friction plate compared with
It is small；When traveling wheel is during rotation with bar contact, and when barrier is smaller, the amplitude of traveling wheel bounce is smaller, at this time
Frictional resistance between first friction plate and the second friction plate is smaller to the buffer function of sliding support plate；The jump of sliding support plate
It is dynamic mainly to be buffered by friction generated between two friction blocks and third friction plate；When traveling wheel during rotation with
Bar contact, and when barrier is larger, the amplitude of traveling wheel bounce is larger, sliding during barrier squeezes traveling wheel
Dynamic support plate will drive the movement of the first mounting blocks relative to bottom plate movement；First mounting blocks are mobile to drive the 4th support plate mobile；
4th support plate is mobile to drive the first friction plate mobile；So that the frictional strength between the first friction plate and the second friction plate adds
Greatly；It is larger by intensity between the first friction plate and the second friction plate when during walking rotation is dynamic with larger bar contact
Friction come buffer in traveling wheel rotation process with the first mounting blocks move up when larger bar contact speed；Pass through
Rubbing to buffer the bounce of traveling wheel between the first friction plate and the second friction plate；When traveling wheel during rotation with obstacle
Object contact, and when barrier is larger, the amplitude of traveling wheel bounce is larger, and the second mounting blocks drive third support plate to moving up at this time
Dynamic amplitude is larger；It is larger that third support plate moves up the amplitude for driving the 4th friction plate to move up；4th friction plate band
The amplitude that dynamic third friction plate moves up is larger；So when third friction plate moves up, in third friction plate and two
Under the cooperation of friction block；Third friction plate will be moved towards the 4th support plate side along the second trapezoidal guide groove；Third friction
Plate movement will rub with two friction blocks；The speed that the second mounting blocks move up can be buffered by the friction；But
It is since the 4th friction plate drives the amplitude that moves up of third friction plate larger；So being supported in third friction plate towards the 4th
During plate side is mobile, two friction blocks will be gradually detached from third friction plate, then contact with the 4th friction plate and
It rubs with the 4th friction plate；The speed that the second mounting blocks move up can be buffered by the friction；Rubbed by third
Rubbing to buffer the bounce of traveling wheel between wiping board and the 4th friction plate and two friction blocks.
The effect of leaf spring is to pass through plate when angles shifts occur between the first support plate and square connecting plate in the present invention
Spring can make the first support plate return to original state with square connecting plate；The effect of the second compressed spring is to protect in the present invention
It has demonstrate,proved and has kept a smaller frictional strength between the first friction plate and the second friction plate in the initial state；Traveling wheel by compared with
When small barrier, so that buffering the main friction by between two friction blocks and third friction plate of traveling wheel bounce to delay
Punching；The effect of opened on third friction plate in the present invention two evacuation square grooves be prevent two friction blocks from third friction plate
Contact is moved to when contacting with the 4th friction plate to be interfered between two friction blocks and third friction plate.
Relative to traditional damper technology, the damper that the present invention designs is pacified by rubbing come the first mounting blocks and second
Fill the upward movement speed of block；The bounce of traveling wheel is buffered by rubbing；Achieve the effect that damping by rubbing.
