Skill and operate with method etc., are described in further detail, to help those skilled in the art to of the present utility model
Bright design, technical scheme have more complete, accurate and deep understanding.
This utility model designs a kind of braking system of electric car, including arrestment mechanism and braking end cap 1, arrestment mechanism bag
Include brake hoop 2, brake rubber block 3, brake rubber block support chip 4, lead screw motor 6, back-moving spring 7 and support column 8；The embedded braking of brake hoop 2
In end cap 1；6 two ends of lead screw motor include screw mandrel；The screw mandrel is inserted in the groove of the brake rubber block support chip 4；The brake
Has the brake rubber block 3 on the side close with the brake hoop 2 of cutaneous branch blade 4；4 position of brake rubber block support chip relies on institute
State support column 8 to fix.
Brake rubber block support chip 4 can be rotated around support column 8.The flexible rotating of brake rubber block support chip 4 can make which in braking
