Embodiment Construction
[0039] In order to make the objectives, technical solutions and advantages of the present invention clearer, the embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that, the embodiments in the present application and the features in the embodiments may be arbitrarily combined with each other if there is no conflict.
[0040] It has been explained in the above background technology that for the brake disc of carbon fiber composite material, it is necessary to use a steel clip to protect the keyway of the moving disc or the static disc in the brake disc, and the current technology of riveting a single steel clip into the keyway of the brake disc is used. In the solution, when the keyway of the brake disc is impacted, the force will be transmitted to the rivet of a single steel clip, which will cause cracks or fractures in the rivet hole of the brake disc and the rivet hole of a single steel clip, ...

The invention provides an impact-resistant combined brake disc steel clamp assembly. The impact-resistant combined brake disc steel clamp assembly comprises a steel clamp, a limiting piece and a rivet. The steel clamp comprises a groove body, double-lug structures are arranged on the two sides of the groove body, the steel clamp is installed in a key groove of the brake disc in a clamped mode through the double-lug structures so as to limit axial displacement of the groove body, and each lug piece of the double-lug structures is arranged to be in an L shape or a mirror image L shape and is installed in cooperation with the profile face of the limiting piece. And each limiting piece is complementary and matched with the corresponding lug piece in shape, is fixedly mounted on the disc surface of the brake disc through a rivet, and is used for limiting the radial displacement of the groove main body in a complementary and matched mounting form with the double-lug structure. According to the technical scheme, the problems that in an existing brake disc key groove protection mode of a single steel clamp, due to the fact that force can be transmitted to a rivet of the single steel clamp, cracks or fractures possibly exist in a brake disc and a rivet hole of the single steel clamp, and the brake disc is damaged are solved.
Description
technical field [0001] The invention relates to, but is not limited to, the technical field of aviation machinery, in particular to an impact-resistant combined brake disc steel clip assembly. Background technique [0002] The aircraft wheel generates braking torque through the friction of the moving disc and the static disc when the aircraft performs landing braking and taxiing on the ground to stop the aircraft. [0003] For new military aircraft or civil aircraft, the brake discs are generally made of carbon fiber composite brakes, which are subjected to high-speed impact during high-speed landing and braking. Steel clips are often used to protect the dynamic disc or static disc keyway in the brake disc to avoid the occurrence of brake discs. damage. At present, a single steel clip is usually riveted in the keyway of the brake disc to achieve the purpose of protecting the brake disc, such as figure 1 shown is a schematic diagram of a single steel clip on an existing bra...
