Abstract
A braking apparatus for a vehicle is disclosed. The present disclosure in at least one embodiment provides a braking apparatus for a vehicle, including a master cylinder configured to supply hydraulic pressure to a wheel brake by a depression of a brake pedal, a first flow path and a second flow path configured to supply the hydraulic pressure by interconnecting the master cylinder and the wheel brake, a pump unit configured to discharge the hydraulic pressure to the first flow path and the second flow path by a drive of a motor, and a pulsation dampener having one end including a damper cap and an opposite end including a support ring and configured to interconnect the first flow path and the second flow path and to mitigate a difference in hydraulic pressure between the first flow path and the second flow path.
Claims11
A braking apparatus for a vehicle, comprising:
- a master cylinder configured to supply hydraulic pressure to a wheel brake in response to a depression of a brake pedal;
- a first flow path and a second flow path each extending in a first direction and configured to supply the hydraulic pressure by interconnecting the master cylinder and the wheel brake;
- a pump unit configured to discharge the hydraulic pressure to the first flow path and the second flow path by a drive of a motor;
- a pulsation dampener having a first end including a damper cap and a second end including a support ring, and configured to interconnect the first flow path and the second flow path and to mitigate a difference in hydraulic pressure between the first flow path and the second flow path, a first flow path extending unit extending in a second direction, different from the first direction, from the first flow path, and a second flow path extending unit extending in the second direction from the second flow path,
- wherein the damper cap includes a space extending partially through the damper cap in the second direction for allowing the first flow path extending unit to extend into the damper cap to connect with the first flow path at a location inside the damper cap, wherein the support ring includes an opening extending completely through the support ring in the second direction, and wherein the opening in the support ring is connected to the second flow path extending unit,
- wherein the first flow path extends completely through the damper cap in the first direction.
