Abstract
The utility model provides a rear wheel drive device of scooter, which comprises a bracket, install the support pipe box on the support, form a contained angle between the axis of support pipe box and the horizontal plane, support pipe box still swing joint has the rear wheel support, the rear wheel support can be rotatory around the axis that sets up the round pin shaft hole on the support pipe box, still install the pulley on the rear wheel support, still install the torsional spring between support and the support pipe box. The utility model discloses compact structure, simple structure and reliable, through form a contained angle between the axis of support pipe box and the horizontal plane, and then make the transmission comes on the support pipe box power by the level of resolving into and two vertical orientations, and then make the frictional force on the pulley to strengthen, make the swing of pulley looks both sides simultaneously to through the effect of torsional spring, make it can make things convenient for the return.
Description
Technical field
This utility model relates to back wheel driving gear and the scooter of a kind of scooter.
Background technology
Scooter is also frog car, Breaststroke Sports Car, frog scooter.Because when riding, apperance exactly likes Rana nigromaculata swimming,
So being roller board.Roller board combines mechanics and principle of human engineering, is that Now Domestic is the safest
The body-building sports bicycle of fashion.It is structural, superprecision test is all done in safety, motility and manipulation, overall
Moulding is sturdy and durable, uses the principle that horizontally slips, and utilizes both legs outward thrust and introversive interior associated form to produce
Thrust, can naturally move to few movable sartorius m. at ordinary times.
But existing scooter is when motion, trailing wheel seems not enough with the frictional force on ground, therefore needs badly and changes
Enter the driving means of scooter rear wheel.
Utility model content
The purpose of this utility model is to solve technical problem involved in background technology, it is provided that a kind of
The back wheel driving gear of scooter and scooter.
This utility model provides the back wheel driving gear of a kind of scooter, including support, described support is pacified
Equipped with support pipe box, between axis and the horizontal plane of described support pipe box, shape is in an angle, described support tube
Set is also connected with rear wheel support, and described rear wheel support can be around the axle being arranged at the pin shaft hole that support tube puts
Line rotates, and described rear wheel support is also equipped with pulley, is also equipped with turning round between described support and support pipe box
Spring.
Preferably, described torsion spring is provided with two elastic ring sets, and the two ends of two described elastic ring sets are prolonged respectively
Extending resilient legs and annular elastomeric circle, described elastic ring set is set in and is arranged at the straight pin that support tube puts
On, described resilient legs is inserted in the perforate being opened on rear wheel support, and described annular elastomeric circle is wrapped in setting
In the boss outer that support tube puts, described straight pin is connected on boss.
Preferably, described support tube puts and is provided with flange, and described rear wheel support is provided with seam, described flange
Work in coordination with seam so that support pipe box and rear wheel support interconnect.
Preferably, described rear wheel support is provided with bottom latch hole, described in be arranged at the pin that support tube puts
It is inserted with latch in axis hole and extends in bottom latch hole so that rear wheel support rotates for axle with latch.
This utility model additionally provides a kind of scooter, including arbitrary described back wheel driving gear, institute
State support, away from one end of support pipe box, pedal, described pedal connecting vehicle frame are installed, described vehicle frame also sets
It is equipped with handle and front-wheel.
In sum, this utility model has the advantage that
This utility model compact conformation, simple in construction and reliable, by axis and the level of described support pipe box
Between face, shape is in an angle, and then support tube is put, and power that transmission comes is broken down into horizontally and vertically two
Individual direction, and then the frictional force on pulley is enhanced, make pulley roll to each side mutually simultaneously, and lead to
Cross the effect of torsion spring so that it can facilitate return.
