Description
Technical Field
The utility model relates to the field of motorcycle and electric vehicle brake systems, in particular to a novel piston structure for a disc brake caliper.
Background
The hydraulic disc brake caliper is fixed on the frame, two brake pads on the caliper are respectively mounted on two sides of the brake disc, and the piston of the wheel cylinder is under the hydraulic action conveyed by the oil pipe to push the brake pads to press the brake disc to generate friction braking, so that the action is just like clamping the rotating disc by using the pliers to force the disc to stop.
One end of each piston is in contact with hydraulic oil conveyed by an oil pipe, the other end of each piston is pushed by the hydraulic oil to press a brake pad, the brake pad is pushed to a brake disc to perform friction braking, a large amount of heat is generated after the brake pad participates in braking, natural wind flows into the brake caliper to perform natural wind cooling heat dissipation on the brake pad due to the fact that the heat dissipation of the brake pad depends on a window formed in the brake caliper in the prior art, but the contact surface of the piston and the brake pad in the prior art is a plane, the heat dissipation speed of the piston is low, and therefore the brake pad (brake pad) is fast in heat fading, slow in heat recovery, low in brake coefficient and poor in brake effect.
SUMMERY OF THE UTILITY MODEL
The technical problem to be solved by the present invention is to solve the above-mentioned deficiencies of the prior art,
a novel piston structure for a disc brake caliper is provided.
In order to achieve the purpose, the utility model provides the following technical scheme: the utility model provides a novel piston structure for dish calliper of stopping, including the piston body, the piston body has one end open-ended inner chamber and keeps away from open-ended one end for the linkage end with hydraulic oil contact, piston body open-ended one end is the braking end with braking piece contact, its characterized in that: the side wall of the braking end is provided with a ventilation structure distributed along the circumference of the side wall.
By adopting the technical scheme, when the existing piston braking end pushes the braking piece to brake, the contact surface of the piston and the braking piece is a plane, the heat dissipation speed of the piston is low, so that the brake piece (braking piece) has high heat fading, low heat recovery and poor braking effect due to the fact that the braking coefficient can be reduced.
The novel piston structure for the disc brake caliper can be further set as follows: the ventilation structure comprises a plurality of convex blocks arranged on the side wall of the braking end and distributed along the circumference and a plurality of concave surfaces arranged between the adjacent convex blocks.
By adopting the technical scheme, when the braking end is contacted with the braking piece to push the braking piece to the brake disc, the braking end is exposed in the external environment, and the concave surface and the convex surface arranged on the braking end enable natural wind to enter the piston through the concave surface, so that the heat dissipation effect of the piston is improved, the heat dissipation speed of the piston is high, the braking coefficient is ensured not to be reduced, and the braking effect is improved.
The novel piston structure for the disc brake caliper can be further set as follows: the end of each lug, which is far away from the braking end, is flush and is arranged on the same horizontal plane. By adopting the technical scheme, one end of each lug, which is far away from the braking end, is arranged to be positioned on the same horizontal plane, so that the braking force of the piston acting on each part of the brake pad is kept consistent when the piston pushes the brake pad to brake the brake disc, and the stability and the braking effect are improved.
The utility model has the beneficial effects that: set up ventilation structure on the basis of guaranteeing original braking effect, make during natural wind can get into the piston through the concave surface, promote the piston radiating effect, make the piston radiating rate fast to guarantee that the braking coefficient can not reduce, promote braking effect.
The present invention will be described in further detail with reference to the accompanying drawings and examples.
