Abstract
A brake caliper utilizes hydraulic oil to brake a disc, and comprises a cylinder body, a piston, a middle element, a base, a chamber and a brake element. The piston is moveably arranged in the cylinder body. The middle element is coupled on the piston, and the middle element and the piston which are mutually coupled relatively move. The base is moveably arranged in the cylinder body and is contacted to the middle element. The chamber is arranged between the base and the cylinder body, and hydraulic oil can be held in the chamber. The brake element is arranged between the piston and the disc. When hydraulic oil is transported to the chamber between the base and the cylinder body, the hydraulic oil drives the base to move, the base drives the middle element and pushes the piston, and the disc is braked through driving the brake element by the piston. The volume of an oil cup of a brake main pump and the volume of the brake main pump are both small, and therefore, the oil cup is easier to be hidden in a vehicle body or other structures which are arranged.

A kind of brake clamp, these brake clamp utilize a hydraulic oil to brake for a disc.The brake clamp comprise a cylinder body, a piston, an intermediary element, a base, a room and a braking member.Piston movably is arranged among the cylinder body.Intermediary element is coupled to piston, can produce relative movement between intermediary element that couples mutually and the piston.Base movably is arranged among the cylinder body and is contacted with intermediary element.Room is arranged between base and the cylinder body, and hydraulic oil can be contained in room.Braking member is arranged between piston and the disc.When hydraulic oil is transported to room between base and the cylinder body, hydraulic oil drives base and moves, and base drives intermediary element and promotes piston, by the piston actuated braking member to brake for disc.
Base comprises a recess, and room comprises the recess of base.
After hydraulic oil was released, brake disc driven plunger moves and intermediary element is subjected to the driving of piston and produces rotation, so to cause the distance between piston and the base to increase.
Be to utilize screw thread and couple mutually between intermediary element and the piston.
The brake clamp more can comprise a bearing, and bearing is arranged between piston and the intermediary element.Bearing is a ball bearing.
The volume and the volume thereof of lubricating cup that the utility model has the advantages that master cylinder brake is all little, makes that so lubricating cup is easier to be hidden among the set car body or other structure

Embodiment
Fig. 3 represents the schematic representation of a brake clamp C of the present invention, a master cylinder brake P and an oil pipe 3 ', and wherein, master cylinder brake P utilizes oil pipe 3 ' and is connected to the clamp C that brakes.Master cylinder brake P comprises a lubricating cup 11 ', a grease chamber 12 ' and a plunger 13 ', and wherein, hydraulic oil W deposits among lubricating cup 11 ' and the grease chamber 12 ', and plunger 13 ' can be exported the hydraulic oil W in the grease chamber 12 '.
Brake clamp C comprises a cylinder body 4, an automatic adjusting mechanism A0, have a base 407, a room 408 of a concave surface 4070, have a braking member 6 of an intenral brake sheet 61 and an outer brake shoe 62.Cylinder body 4 comprises a round barrel shape casing wall 413, a claw 414 and an oil inlet hole 4081, and wherein, the inside and outside brake shoe 61,62 of braking member 6 is arranged at claw 414, and automatic adjusting mechanism A0 and base 407 are arranged on the round barrel shape casing wall 413.Room 408 is for being formed at the concave surface 4070 of base 407 and the space between the cylinder body 4, and this room 408 is connected in the grease chamber 12 ' of master cylinder brake P via the oil inlet hole 4081 of cylinder body 4, oil pipe 3 '.Intenral brake sheet 61 has a projection 611.In the present embodiment, room 408 has comprised the recess 407r that the concave surface 4070 of base 407 is constituted.
Automatic adjusting mechanism A0 comprises that a C type buckles 401, one spring seat 402, a pressure spring 403, an intermediary element 404, a ball bearing 405, a pad 406 and a piston 5.The center axial region 50 of piston 5 has an internal thread part 51, and intermediary element 404 has an external thread part 4041.The C type buckles 401 in order in regular turn spring seat 402, pressure spring 403, pad 406, ball bearing 405 are positioned on the base 407 with intermediary element 404.When piston 5 is arranged at the round barrel shape casing wall 413 of cylinder body 4, the internal thread part 51 of piston 5 and the external thread part 4041 mutual interlocks of intermediary element 404 at this moment.On the contact area between the intenral brake sheet 61 of piston 5 and braking member 6, can not rotate in order to limited piston 5 by the projection 611 of intenral brake sheet 61.One oil sealing 411 is sheathed between the casing wall 413 of the circumferential surface 4071 of base 407 and cylinder body 4, produces the phenomenon that leaks outside improperly by oil sealing 411 to avoid hydraulic oil W.
Under the start of the plunger 13 ' of master cylinder brake P, hydraulic oil W in the grease chamber 12 ' of master cylinder brake P is delivered to the room 408 between base 407 and the cylinder body 4 via oil pipe 3 ', and utilize hydraulic oil W can promote base 407 again, base 407 overcame the resiliently deformable of oil sealing 411 and promoted intermediary element 404, piston 5 in order this moment, so carried out clamping and reached braking action for brake disc 63 with the inside and outside brake shoe 61,62 that drives braking member 6.After the hydraulic pressure of the hydraulic oil W of master cylinder brake P is released, oil sealing 411 retracts base 407, the inside and outside brake shoe 61,62 of braking member 6 and piston 5 braked disc 63 rotation and unclamp naturally, pressure spring 403 is pushed pad 406, ball bearing 405, intermediary element 404 to base 407, this moment intermediary element 404 be subjected to pullling of piston 5 drive produce rotation down and cause piston 5 simultaneously with base 407 between the distance increase, the space that can increase for the wearing and tearing because of the inside and outside brake shoe 61,62 of braking member 6 compensates by this.In other words, with regard to the start of whole brake clamp C, master cylinder brake P can not need the hydraulic oil W of brake clamp C is replenished, and the volume of the lubricating cup 11 ' of master cylinder brake P and volume thereof all can so make lubricating cup 11 ' be easier to be hidden among a set car body (figure is mark not) or other structure less than the known lubricating cup 11 among Fig. 2.
