Description

Brake caliper structure

The present invention relates to a brake caliper structure, and more particularly to a brake caliper structure that can effectively prevent a brake to cause a sheet and a caliper body to strike each other.

Referring to FIGS. 1 and 2 , a conventional brake caliper structure 1 mainly includes a caliper body 10 , two support rods 20 , two brakes to make the sheet 30 and two positioning springs 40 .

The support rod 20 is coupled to the caliper body 10.

The brake shoe 30 is sleeved on the support rod 20.

The positioning spring 40 is also sleeved on the support rod 20, and the positioning spring 40 is pressed against the brake to cause the sheet 30 to fix the sheet 30 to the caliper body 10.

However, in the case where the brake caliper structure 1 is mounted on a locomotive, the vibration generated when the locomotive is running often causes the brake to cause the sheet 30 and the caliper body 10 to strike each other, thereby generating noise.

The present invention basically employs the features detailed below in order to solve the above problems. That is, the present invention includes a caliper body having at least one retaining wall; at least one support rod coupled to the caliper body; at least one brake lining, sleeved over the support rod, and having a V-shaped recess Slot; and at least one positioning reed, sleeve Above the support rod, and pressing against one side of the V-shaped groove of the brake to force the brake to abut the blade against the retaining wall of the caliper body.

Meanwhile, according to the brake caliper structure of the present invention, the V-shaped groove is formed on the brake urging piece in such a manner as to be offset from the central axis of the brake lining, and the positioning spring is symmetrical to The central axis is pressed against the side of the V-shaped groove.

In the present invention, the V-shaped groove is formed at a central axis of the brake wrap, and the positioning spring is pressed against the V-shaped groove in a manner asymmetric with respect to the central axis. The side.

The above described objects, features and advantages of the present invention will become more apparent from the description of the appended claims.

The above and other technical contents, features and advantages of the present invention will be apparent from the following detailed description of the preferred embodiments. The directional terms mentioned in the following embodiments, such as up, down, left, right, front or back, etc., are only directions referring to the additional drawings. Therefore, the directional terminology used is for the purpose of illustration and not limitation.

First embodiment

Referring to FIG. 3 and FIG. 4 , the brake caliper structure 100 of the present embodiment is applied to a locomotive M, and mainly includes a caliper body 110 , two support rods 120 , two brakes to make the sheet 130 , and two positioning positions . Reed 140. Here, FIG. 4 shows only one brake shoe 130 and one positioning spring 140.

As shown in FIG. 4, the caliper body 110 has a retaining wall 111.

The two support rods 120 are coupled to the caliper body 110.

The brake shoe 130 is sleeved on the two support bars 120, and the brake shoe 130 has a V-shaped groove 131. In the present embodiment, the V-shaped recess 131 is formed on the (top) of the brake wrap 130 in a manner offset from the center axis C of the brake wrap 130.

The positioning spring 140 is sleeved on the two support rods 120, and the positioning spring 140 is pressed against one side 131a of the V-shaped groove 131 of the brake shoe 130. In more detail, the positioning spring 140 is pressed against the side 131a of the V-shaped groove 131 in a manner symmetrical to the center axis C of the brake 130. Here, as shown in FIG. 4, the positioning spring 140 is pressed against one of the one side 131a of the V-shaped groove 131. The downward pressure F can be decomposed into a downward vertical thrust Fv and a rightward horizontal thrust Fh. The horizontal thrust Fh can force the brake to cause the sheet 130 to abut against the retaining wall 111 of the caliper body 110.

Second embodiment

In the present embodiment, the same elements as those of the first embodiment are denoted by the same reference numerals.

Referring to FIG. 3 and FIG. 5 , the brake caliper structure 100 ′ of the present embodiment is applied to the locomotive M, and mainly includes a caliper body 110 , two support rods 120 , two brakes to make the sheet 130 ′ and two Positioning the reed 140'. Here, Fig. 5 shows only one brake shoe 130' and one positioning spring 140'.

The brake shoe 130' is sleeved over the two support bars 120, and the brake shoe 130' has a V-shaped groove 131. In the present embodiment, the V-shaped groove 131 is formed at a central axis C of the brake shoe 130'.

The positioning spring 140' is sleeved over the two support rods 120, and the positioning spring 140' is a side 131a of the V-shaped groove 131 that is pressed against the brake shoe 130'. In more detail, the positioning spring 140' is pressed against the one side 131a of the V-shaped groove 131 in a manner asymmetric with respect to the central axis C. Similarly, as shown in FIG. 5, the positioning reed 140' is pressed against one of the one side 131a of the V-shaped groove 131, and the downward pressure F can be decomposed into a downward vertical thrust Fv and a rightward horizontal thrust Fh. This horizontal thrust Fh can force the brake to cause the sheet 130' to abut against the retaining wall 111 of the caliper body 110.

The other components, features, and operation modes of the present embodiment are the same as those of the first embodiment. Therefore, in order to make the contents of the present specification clearer and easier to understand, the repeated description thereof will be omitted herein.

In summary, in the brake caliper structure disclosed by the present invention, the horizontal thrust generated between the V-shaped groove of the blade by the positioning spring and the brake can force the brake to tightly abut the caliper The body retains the wall, so the brakes will not cause another collision between the piece and the caliper body due to vibration, so that noise can be effectively avoided.

Although the present invention has been disclosed in its preferred embodiments, it is not intended to limit the present invention, and it is possible to make some modifications and refinements without departing from the spirit and scope of the present invention. The scope of the invention is defined by the scope of the appended claims.
