Detailed description of the invention
Below in conjunction with the accompanying drawings, the most involved by embodiment being described the detailed description of the invention to the present invention each component
Shape, structure, mutual alignment between each several part and annexation, the effect of each several part and operation principle, manufacturing process and
Operate with method etc., be described in further detail, to help those skilled in the art to the inventive concept of the present invention, skill
Art scheme has more complete, accurate and deep understanding.
The present invention designs a kind of braking system of electric car, and including arrestment mechanism and braking end cap 1, arrestment mechanism includes system
Rotating ring 2, brake rubber block 3, brake rubber block support chip 4, lead screw motor 6, back-moving spring 7 and support column 8；Brake hoop 2 embeds braking end cap 1
In；Lead screw motor 6 two ends include screw mandrel；Described screw mandrel inserts in the groove of described brake rubber block support chip 4；Described brake rubber block supports
With described brake rubber block 3 on the side that sheet 4 is close with described brake hoop 2；Described brake rubber block support chip 4 position relies on described support
Post 8 is fixed.
Brake rubber block support chip 4 can rotate around support column 8.The flexible rotating of brake rubber block support chip 4 can make it in braking
During quickly act on, in Recovery Process, also be able to snap action simultaneously, shorten braking and the time replied, intensified response
Sensitivity.
Adjacent two panels brake rubber block support chip 4 is provided with opening in the side that support column 8 is close with brake hoop 2.Opening is V
Type, can effectively prevent adjacent two panels brake rubber block support chip 4 from colliding in braking procedure, thus affects braking effect
Really.Make whole braking procedure more smooth.
Being provided with female thread in the groove of brake rubber block support chip 4, the screw mandrel at this female thread and lead screw motor 6 two ends is provided with
External screw thread matches.Lead screw motor 6 can more be accurately controlled when brake rubber block support chip 4 takes braking, when just replys
Often state.
Brake rubber block support chip 4 is the most a piece of.Being not limited to a piece of, multi-disc brake rubber block support chip realizes braking effect more.
At least one piece of brake rubber block 3 is adhered to, it would however also be possible to employ multi-disc brake rubber block 3 is the most attached on adjacent brake rubber block support chip 4
On brake rubber block support chip 4, all can reach the effect of skidding.
Lead screw motor 6 number at least one.Being not limited to one, multiple lead screw motor 6 are with the use of being better achieved
Braking function.
Operation principle:
When there is brake hard, lead screw motor 6 is under the effect controlling electric current, and the screw mandrel at its two ends can be along its axis direction
Protrude in the groove of brake rubber block support chip 4 and contact with bottom portion of groove.Brake rubber block support chip 4 is by lead screw motor 6 axle
To the effect of power, rotate round support column 8, and the back-moving spring 7 in the middle of adjacent brake rubber block support chip 4 is in stretching shape
State.Now, the brake rubber block 3 being attached on brake rubber block support chip 4 contacts with brake hoop 2 in the rotation process of brake rubber block support chip 4,
Thus reach the effect of braking.
After brake hard terminates, lead screw motor 6 is under the effect of Reverse Turning Control electric current, and the screw mandrel at its two ends can be along its axle
Retracting and exit the bottom portion of groove of brake rubber block support chip 4 in line direction, does not contacts with bottom portion of groove.Brake rubber block support chip 4 is resetted
Spring 7, rotates round support column 8, and brake rubber block support chip 4 is returned to original position, and in the middle of adjacent brake rubber block support chip 4
Back-moving spring 7 also returns to original state state, now, the brake rubber block 3 being attached on brake rubber block support chip 4 turning at brake rubber block support chip 4
Do not contact with brake hoop 2 during Dong, thus be returned to normal condition.
