Description

Technical Field

[0001] The utility model relates to the field of automobile brake rotors, in particular to an automobile brake rotor with a hollow structure. Background Art

[0002] The rotor for automobile brakes usually refers to the rotor disc in the brake system, also known as the brake disc or brake disc. It is a round metal disc, usually installed on the wheel, and used in conjunction with the brake pad to slow down or stop the movement of the vehicle through friction. When the driver steps on the brake pedal, the brake pad clamps the rotor disc, generating friction, thereby slowing down or stopping the vehicle;

[0003] A Chinese patent with publication number CN115949683A discloses a disc brake rotor, including a first brake pad, a second brake pad, and a heat sink arranged between the first brake pad and the second brake pad. During braking, the first brake pad and the second brake pad rub against the stator of the disc brake system, and the heat generated can be dissipated through the heat sink.

[0004] When the disc brake rotor of the above patent contacts the brake pad and brakes, both sides of the brake pad will contact the brake pad and generate high temperature. The high temperature will be generated quickly due to the friction on both sides, and the heat position cannot quickly contact the high-speed flowing gas, so the heat dissipation effect is low, which affects the long-term continuous use of the automobile brake rotor.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] In order to solve the problem that when the existing disc brake rotor contacts the brake pad and brakes, both sides of the brake pad will contact the brake pad and generate high temperature, the high temperature will be quickly generated due to the friction on both sides, and the heat position cannot quickly contact the high-speed flowing gas, the heat dissipation effect is low, and the long-term continuous use of the automobile brake rotor is affected, this embodiment provides the following technical solutions:

[0021] A hollow structure automobile brake rotor comprises a first bonding sheet 1, a second bonding sheet 2 is arranged at one end of the first bonding sheet 1 in a mirror image, and a hollow cavity 3 is arranged between the second bonding sheet 2 and the first bonding sheet 1. Figure 1 As shown, the external brake pad will adhere to the first bonding sheet 1 and the second bonding sheet 2 during the braking process, and the adhesion will generate friction respectively. The heat will be transferred to the inside of the first bonding sheet 1 and the second bonding sheet 2 respectively, and the heat will be diverted to avoid heat accumulation in one place;

[0022] In this embodiment, the other end of the first bonding sheet 1 and one end of the second bonding sheet 2 are both provided with a connecting sheet 4. Figure 1 and Figure 2 As shown, the connecting sheet 4 is welded and fixed to the first bonding sheet 1 and the second bonding sheet 2, and the connecting sheet 4 that is extended and welded and fixed can facilitate subsequent installation and fixation;

[0023] In this embodiment, heat sinks 7 for heat dissipation are provided at both the front and rear ends of the hollow cavity 3, and contact surfaces 12 are provided on the first bonding sheet 1 and the second bonding sheet 2 facing the connecting sheet 4. Figure 2 and Figure 4 As shown, the contact surface 12 contacts the brake pad and completes the braking, the heat sink 7 is welded and fixed to the first bonding sheet 1 and the second bonding sheet 2, and the welding position of the heat sink 7 overlaps with the position of the contact surface 12. The heat generated by friction will be directly transferred to the heat sink 7, transferred to the surface of the heat sink 7 and increase the heat dissipation area, thereby improving the heat dissipation effect;

[0024] In this embodiment, an air push block 9 is disposed around the outside of the heat sink 7, and the air push block 9 is provided with an inclined surface 10 facing outward. Figure 2 and Figure 3As shown, connecting strips 8 are welded on both sides of the outside of the air push block 9, and the connecting strips 8 are welded and fixed to the air push block 9. The two ends of the connecting strip 8 are respectively fixedly connected to the first bonding sheet 1 and the second bonding sheet 2 through the support sheet 5. The connection between the support sheet 5, the connecting strip 8 and the air push block 9 can realize the rotation of the air push block 9 during the rotation of the rotor. The rotation of the air push block 9 can discharge the internal heat and gas to avoid heat accumulation inside the rotor. On the other hand, the support of the support sheet 5, the connecting strip 8 and the air push block 9 can improve the bearing capacity of the rotor.

[0025] In this embodiment, bolt connection holes are arranged around the interior of the connecting piece 4, and the bolt connection holes penetrate and extend to the front and rear ends of the connecting piece 4. Figure 1 and Figure 4 As shown, during the installation process, the connecting bolts pass through the connecting piece 4 and fix the rotor to cope with subsequent braking;

[0026] In this embodiment, the bolt connection hole is surrounded by a second support ring 11 toward the center of the rotor, and the bolt connection hole is surrounded by a first support ring 6 toward the outside. Figure 4 As shown, the bolt fixing position is supported and wrapped by the first support ring 6 and the second support ring 11, which improves the bearing capacity and facilitates the subsequent fixing and removal of the bolts. The two ends of the first support ring 6 and the second support ring 11 are welded and fixed to the first bonding sheet 1 and the second bonding sheet 2 respectively.

[0027] Working principle: When using the automobile brake rotor and braking, the user steps on and makes the brake pad contact the contact surface 12 position on the surface of the first bonding sheet 1 and the second bonding sheet 2. The heat at the contact surface 12 position will be transferred to the corresponding heat sink 7 position, and the heat sink 7 in the rotating state will quickly contact the heat and achieve heat dissipation. While dissipating heat, the connecting bar 8 in the rotating state will also rotate. The rotation of the connecting bar 8 is coordinated with the rotation of the protruding air push block 9. The inclined surface 10 on the surface of the air push block 9 can discharge the heat at the internal heat sink 7 position and discharge it to the outside of the hollow cavity 3 to achieve efficient heat dissipation.
