In the restriction slot for placing stop block.
Through the above technical solutions, when spring leaf is installed in caliper bracket, the stop block on spring leaf extend into limit
Determine inside slot, when spring leaf is subject to be directed toward the external force away from caliper bracket one side, the lateral wall of stop block is with limiting the interior of slot
Cell wall offsets so that spring leaf is not easy to separate with caliper bracket under external force so that the use of the brake caliper becomes more
Add smooth.
Preferably, it is coated with rubber sheet gasket on the stop block lateral wall.
Through the above technical solutions, rubber sheet gasket is coated in stop block, and when stop block extend into and limits inside slot, rubber
The lateral wall of glue gasket offsets with limiting the internal groove side wall of slot, and larger due to limiting the coefficient of friction between slot and rubber sheet gasket,
So stop block is not easy to deviate from from restriction slot.
Preferably, it is equipped with mounting hole on the spring leaf, the number at least two of the mounting hole and is uniformly distributed
On spring leaf, fin is set, the fin is passed through from mounting hole and offseted with spring leaf lateral wall in the caliper bracket.
Through the above technical solutions, when needing spring leaf being installed in caliper bracket, the fin on spring leaf is controlled
It is opposite with the mounting hole in caliper bracket, afterwards spring leaf is controlled to be moved towards caliper bracket one side, and fin is from mounting hole
It passes through.When spring leaf and caliper bracket offset, control fin bending so that the lateral wall of fin and the lateral wall of caliper bracket
It offsets so that spring leaf is not easy the caliper bracket during the use of the brake caliper and separates.
Preferably, the spring leaf is provided with to place the placing groove of fin on the end face of caliper bracket.
Through the above technical solutions, when spring leaf is pressed in caliper bracket by fin, fin is located at placing groove
Inside, and the lateral wall of fin and the internal groove side wall of placing groove offset, and the slot of lateral wall and placing groove of the fin away from spring leaf
Mouth flushes, and so during the brake caliper is used, the movement that fin is not easy to brake pad impacts so that the braking
The use process of clamp becomes more smooth.
Preferably, the brake pad is towards oil filler point is provided on the end face of spring leaf, and the oil filler point is away from spring leaf
End on be connected with to store the shoe cream room of lubricating oil.
Through the above technical solutions, during the brake caliper is used, the lubricating oil inside shoe cream room is gradually from note
It flows out and is flow between brake pad and spring leaf in oilhole, lubricating action is played to the movement of brake pad so that brake pad and bullet
It is not easy to wear due to relative movement between reed, ensure that the service life of the brake caliper to a certain extent.
In conclusion the utility model having the beneficial effect that in contrast to the prior art：
1st, lubricant layer is coated on spring leaf, so during the use of brake caliper, between brake pad and spring leaf
Frictional force it is smaller so that abrasion is less prone between brake pad and spring leaf, ensure that making for brake caliper to a certain extent
Use the service life；
2nd, coated with noise reduction layer on lubricant layer, so during the brake caliper is used, brake noise is smaller.
