Specific implementation mode
The embodiments of the present invention are further illustrated below in conjunction with attached drawing.
It refers to shown in attached drawing 1 and attached drawing 2, a kind of bicycle or trail bike rear axle arrangement, including behind left side
Bracing strut 2, second bearing 4, band are from the wheel hub 5 of dynamic interlocking teeth, 3rd bearing 6, active jaw 7, right side bracket of back axle 9 and rear axle
10；The wheel of the bicycle or trail bike is connected to the band from the wheel hub 5 of dynamic interlocking teeth by spoke, described
Band the middle part of the rear axle 10 is socketed in by the second bearing 4 and 3rd bearing 6 from the wheel hub 5 of dynamic interlocking teeth；Institute
The both ends for the rear axle 10 stated are equipped with helical spline, and the active jaw 7 adaptation is socketed in the helical spline of the rear axle 10
On, it is located at the right side of the rear axle 10；The drive sprocket of the bicycle or trail bike is socketed in the rear axle
On 10 spline, it is located at the right side of the rear axle 10, the both ends of the rear axle 10 pass through the left side rear axle branch respectively
Frame 2 and right side bracket of back axle 9 are fixed on through bolt on the vehicle frame of the bicycle or trail bike.
The left end of the rear axle 10 is socketed with thrust pin 1, is located at the left side of the left side bracket of back axle 2, with limitation
The axial position of rear axle 10.
Be socketed with spring on the rear axle 10, be located at the band from the slave dynamic interlocking teeth of the wheel hub 5 of dynamic interlocking teeth with it is described
Active jaw 7 between.
The drive sprocket of the bicycle or trail bike is rigidly connected with the rear axle 10.
The rear axle 10 passes through the first bearing 3 and fourth bearing 8 and the bicycle or trail bike
Vehicle frame connection.
The left side bracket of back axle 2, second bearing 4, band from the wheel hub 5 of dynamic interlocking teeth, 3rd bearing 6, active jaw 7,
Right side bracket of back axle 9 and rear axle 10 are coaxially disposed.
First bearing 3, second bearing 4,3rd bearing 6 and the fourth bearing 8 is 6201 bearings.
The utility model realizes that the combination and disconnection of power transmission, the jaw clutch are disobeyed using a jaw clutch
By external power source drive, active part is mounted on the helical spline of rear axle, main when main secondary part generates speed difference
Dynamic interlocking teeth 7 is horizontally slipped by responsive to axial force, so realize dental inlay combination with detach.Rear axle 10 be shaft, by bearing with
Vehicle frame upper fixed seat coordinates.
When vehicle gives it the gun, drive sprocket rotating speed is more than vehicle wheel rotational speed, since sprocket wheel is rigid by spline with rear axle 10
Property connection, therefore 10 rotating speed of rear axle be more than vehicle wheel rotational speed.Due to the presence of helical spline, active jaw 7 can be by one to the left
Axial force, when power is more than spring force, active jaw 7 slides to the left, is combined with from dynamic interlocking teeth, and band motor car wheel raises speed.Work as vehicle
When sliding or slow down, due to the effect of spring force, active jaw 7 slides to the right, and principal and subordinate's dynamic interlocking teeth separation, wheel only passes through two
A 6201 bearing connects with rear axle 10, and resistance of taxing is small.
By taking bicycle as an example, drive system is equipped with flywheel, the right end for being fixed on rear axle is screwed within flywheel, with spine
Wheel connects, and keeps same plane with preceding sprocket wheel, and be connected with preceding sprocket wheel by chain.When stepping foot-operated forward, chain band
Dynamic flywheel rotates forward, and flywheel drives ratchet to be rotated to locking direction, and at this moment flywheel drives rear wheel, and bicycle is made to advance.
When sliding, ratchet is rotated to line of travel, plays the role of disconnecting power train.Trail bike rear axle arrangement form and its phase
Seemingly, play the role of engagement also with mechanical clutch or disconnect power train.
