Description

Vehicle brake caliper structure

The present invention relates to a brake caliper structure for a vehicle, and particularly relates to an innovative structure of a brake caliper in which a piston can generate heat convection to dissipate heat and avoid leakage or seizure caused by high temperature deformation of the piston.

Referring to the fifth figure, the brake caliper (1) for a vehicle usually includes a brake caliper (1) on both sides, and an oil chamber (111) is formed in the brake caliper body (11) to allow The device piston (12), the piston (12) abuts the piece (13). When the driver steps on the brake pedal or presses the brake handle (not shown), the piston (12) in the brake caliper is pushed by pressurizing the brake oil, so that the piston (12) pushes the blade. (13) To clamp the brake disc (not shown), so that the disc (13) is rubbed against the disc, so that the brake disc stops rotating, and the tire (not shown) stops rotating. Achieve the effect of stopping the vehicle.

However, when the sheet is rubbed against the disc to stop the rotation of the disc, the heat generated by the disc rubbing the disc will be transmitted to the piston, because the piston and the disc are in close contact with each other. In the past state, the thermal energy accumulated on the piston cannot be dissipated, and the piston will be deformed under high temperature for a long time, which may cause a gap between the piston and the oil chamber and may cause oil leakage, or the outer diameter of the piston may no longer be It is stuck with the oil indoor diameter and is stuck, so that the action of the brake can not be carried out, which jeopardizes the safety of driving.

Today, the creator developed the structure of the case in view of the above situation to improve the use of the existing structure.

The main purpose of the present invention is to provide a brake caliper structure for a vehicle, which mainly achieves the effect of avoiding leakage or seizure of the piston due to high temperature deformation by enabling the piston to have a structure capable of generating heat convection to dissipate heat. Make sure driving is safe.

The main purpose and effect of the above creations are achieved by the following specific technical means:

The utility model relates to a brake caliper structure for a vehicle, which comprises a brake caliper body corresponding to two corresponding settings, wherein the brake caliper body has at least one oil chamber, and one of the brake caliper bodies is provided with an oil inlet, the oil inlet is connected with the oil chamber, and the oil is introduced. The port is connected to a master cylinder at the same time, and a piston is arranged in the oil chamber; the oil chambers of the body of the second brake caliper are connected by pipelines; and the first brakes are respectively abutted against the pistons disposed on the body of the second brake caliper And the second second brakes are respectively disposed on the inner side of the first brakes and are used for cooperating to clamp the brake discs; the piston abuts the first brake to set a plurality of slots on one end of the slide; The convection is generated by the vacancies to dissipate heat, and the piston is prevented from leaking or being stuck due to high temperature deformation.

The brake caliper structure for a vehicle as described above, wherein the first brake is a piece of iron.

The brake caliper structure for a vehicle as described above, wherein the brake caliper body is relatively locked.

The brake caliper structure for a vehicle as described above, wherein the brake caliper body is integrally cast or die-cast.

In order to make the technical content, creative purpose and the effect achieved by this creation more complete and clear, please elaborate below, and please refer to the drawings and drawings:

Please refer to the first to fourth figures, which are respectively an exploded view, a three-dimensional combination diagram, a combined top view and a side cross-sectional view of the brake caliper structure of the vehicle.

The vehicle brake caliper structure of the present invention includes:

The two correspondingly arranged and arranged the brake caliper body (2) on the two sides, the brake caliper body (2) on each side has at least one oil chamber (22), and one of the brake caliper bodies (2) is provided with oil. Port (21), the oil inlet (21) is connected with the oil chamber (22), and the oil inlet (21) is simultaneously connected to a brake master cylinder (not shown), the brake master cylinder, the oil inlet (21) and The oil chamber (22) is accommodated with brake oil; wherein the two brake caliper bodies (2) are locked relative to each other, or are integrally cast or die-cast; the oil chamber of the second brake caliper body (2) (22) Connected by a pipeline (23);

a plurality of pistons (3) are mounted in the oil chamber (22) and protrude from an inner side surface of the brake caliper body (2), the piston (3) protruding from an inner side surface of the brake caliper body (2) One end is provided with a plurality of missing slots (31);

The first brake ordering piece (4) is respectively disposed on the inner side of the brake caliper body (2) on both sides, and the outer side surface of the piece (4) is abutted against the piston (3) by the first brake. One end of the slot (31), wherein the first brake (4) is an iron piece;

The second brakes (5) are respectively placed on the inner side of the first brakes (4), and the second brakes are used to make the cooperation of the slides (5) clamp the brake discs (in the figure). Not indicated).

Please refer to the third, fourth and fifth figures. When the driver steps on the brake pedal or presses the brake handle (not shown), the brake oil is pressurized from the brake oil to the intake pump through the oil inlet ( 21) Entering the oil chamber (22) of one of the brake caliper bodies (2), and then entering the oil chamber (22) of the other brake caliper body (2) by the pipeline (23) to push the brake caliper body through the brake oil (2) The pistons (3) in each of the oil chambers (22) move toward the inside of the brake caliper body (2), and the piston (3) abuts the piston (3) due to the first brake, so the piston (3) The action of projecting toward the inside of the brake caliper body (2) will push the first brake to cause the piece (4) to cause the first brake to cause the piece (4) to be displaced in the direction of the brake disk to be transparently disposed. The first brake causes the second brake on the inner side of the piece (4) to cause the piece (5) to be clamped to the brake disk (not shown), and the second brake is used to make the piece (5) rub the brake disk. The way the brake disc stops rotating and makes the tire Shown) stops rotating, the vehicle brakes to achieve the effect of the stop.

Please refer to the third, fourth and fifth figures. When the second brake (5) rubs the brake disc to stop the rotation of the brake disc, the second brake causes the piece (5) to rub the brake disc. The heat energy is transmitted to the respective pistons (3) via the first brake, and the plurality of slots (31) are provided on one end of the piston (3) and the first brake to make the sheet (4) abut. So that the piston (3) abuts the first brake to make a gap between the end of the piece (4) and the first brake (4) instead of being in a close-fitting state, and has the effect of heat convection. Therefore, the heat energy transmitted to the piston (3) can be dissipated by the heat convection effect generated by the arrangement of the vacancies (31), so that the piston (3) is prevented from being deformed by being exposed to high temperature for a long time. , effectively improving the oil leakage caused by the gap between the piston (3) and the oil chamber (22), and improving the outer diameter of the piston (3) due to the deformation of the piston (3) and the oil chamber (22) The inner diameter fits into the stuck state, making the brakes move It can be carried out smoothly, to ensure road safety.
