Detailed Description

As shown in FIG. 1, the single cylinder brake caliper for the small unmanned vehicle comprises a caliper body 1, a caliper inner brake block 3, a caliper outer brake block 5, a piston 6 and a bracket 2.

The caliper is characterized in that a cavity is formed in the caliper body 1, the cavity of the caliper body 1 is matched with the brake disc 8, and the caliper inner brake block 3 is arranged in the cavity of the caliper body 1 through the support 2. The bracket 2 is U-shaped, and the caliper inner brake block 3 is matched with the U-shaped opening of the bracket 2.

The caliper brake pads 3 are disposed inside the brake disc 8.

And the outer side of the brake disc 8 is provided with a caliper outer brake block 5, and the caliper outer brake block 5 is in sliding fit with an outer brake block sliding shaft 9 on the bracket 2 through a sliding sleeve 12.

A piston 6 is arranged in the caliper body 1, and the piston 6 is matched with the caliper inner brake block 3. And a piston rectangular ring 7 matched with the caliper body 1 is arranged on the circumferential surface of the piston 6. The piston rectangular ring 7 is made of rubber.

The left side and the right side of the caliper body 1 are both provided with a main sliding shaft 10, the main sliding shaft 10 is fixedly installed on a base of the brake disc 8 through a support 2, and the outer side of the main sliding shaft 10 is provided with an outer brake block sliding shaft 9.

The left lower corner and the right lower corner of the caliper outer brake block 5 are both provided with sliding sleeves 12 matched with the outer brake block sliding shafts 9.

The upper edge in the cavity of calliper 1 is provided with brake leaf spring 4, be provided with on the brake leaf spring 4 with calliper outer brake pads 5 cooperation brake leaf spring installation is detained 13.

And the top end of the caliper body 1 is provided with a caliper body oil inlet 11 matched with the piston 6.

And a semicircular mounting hole 14 for mounting the piston 6 is formed in the outer side of the clamp body 1.

The working process of the utility model is as follows:

during braking, hydraulic oil enters the caliper through the caliper body oil inlet hole 11, the piston 6 is pushed to act under the action of the hydraulic oil pressure, the piston 6 pushes the caliper inner brake block 3 to move towards the brake disc 8 along the inner wall of the U-shaped opening of the bracket 2 until the caliper inner brake block 3 is pressed against the brake disc 8, meanwhile, the brake disc 8 provides a reaction force for the piston 6, meanwhile, the piston cylinder body of the caliper body 1 is also subjected to the hydraulic oil pressure identical to that of the piston 6, so that the whole caliper body 1 and the caliper outer brake block 5 move towards the brake disc 8 along the outer brake block sliding shaft 9 until the caliper body 1 and the caliper outer brake block 5 are pressed against the other side of the brake disc 8. The caliper inner brake block 3 and the caliper outer brake block 5 on the two sides of the brake disc 8 are stressed equally to clamp the brake disc 8, and friction force is generated to force the brake disc 8 to stop rotating, so that the brake process is completed.

After the brake fluid pressure is released, because of the effect of the piston rectangular ring 7, the piston cylinder of the caliper body 1 is in a negative pressure state, the atmospheric pressure pushes the piston 6 back to the original position, so that the caliper inner brake block 3 is not pressed against the brake disc 8, similarly, under the effect of the negative pressure and the brake leaf spring 4, the atmospheric pressure and the brake leaf spring 4 move the whole caliper body 1 and the caliper outer brake block 5 along the outer brake block sliding shaft 9 to the opposite direction of the brake disc 8, and the caliper inner brake block 3 and the caliper outer brake block 5 move to two sides respectively because of the end face jump generated by the rotation of the brake disc 8 in the vehicle running process, thereby generating a gap and completing the brake releasing process.
