Abstract
Description
The present invention relates to a caliper brake for an automobile.
2. Description of the Related Art Generally, a caliper brake for an automobile is a device for braking a brake pad by bringing the brake pad into close contact with the brake disk, so that the brake pad moved by hydraulic pressure is brought into close contact with the brake disk interlocked with the wheel.
The
A
A lower end of the
When the caliper brake is thus configured, the pressure of the vacuum booster acting as the brake pedal is depressed causes the brake oil of the master cylinder to flow into the
At this time, the
In the above process, the contact of the
2 and 3, the conventional
However, during the pressing of the
Further, in order to provide sufficient restoring force to the
Since the
A technical object of the present invention is to provide a seal mounting structure for an automotive caliper brake in which damage to a seal can be prevented in advance even when a brake fluid is used in a small amount and the drag phenomenon can be minimized.
In order to achieve the above object, a seal mounting structure for an automotive caliper brake according to an embodiment of the present invention is a seal mounting structure for an automotive caliper brake in which a seal is mounted between a piston and a cylinder, A seal mounting groove formed in the portion; A leading end wall forming a leading end boundary portion of the seal mounting groove with respect to a direction in which the piston is pressed; A rear end wall forming a rear end boundary of the seal mounting groove with reference to a direction in which the piston is pressed; And a bottom surface forming the bottom of the seal mounting groove, wherein the end wall comprises: an inner surface constituting a portion in contact with the seal; And an end surface constituting a portion in contact with the piston, and the edge between the inner surface and the end surface is chamfered in a convex round shape.
The rounded corner may be formed in a non-contact state with the piston.
The volume of the tip end wall chamfered in the round shape can be made larger than the volume of the tip end wall in the chamfered state and smaller than the volume of the tip end wall in the state before chamfering.
As described above, the seal mounting structure of the caliper brake for an automobile according to the embodiment of the present invention can have the following effects.
According to the embodiment of the present invention, since the edge of the end wall constituting the seal mounting groove is chamfered into a convex round shape, the volume of the seal mounting groove can be reduced as compared with the existing chamfered oblique technology, The drag phenomenon can be minimized even if the liquid is used in a small amount and the seal can be prevented from being damaged due to the round shape.
