Description

Technical Field

[0001] The utility model belongs to the technical field of calipers, and in particular relates to a caliper for a high-speed railway brake system. Background Art

[0002] The caliper is a key component in the vehicle's braking system. It is mainly responsible for converting the hydraulic or pneumatic pressure of the braking system into friction force to clamp the wheel brake disc, thereby achieving the function of slowing down or stopping the vehicle. High-speed rail is an important means of transportation in modern travel. It has a higher driving speed and can quickly take people to their destination. During the driving process, the high-speed rail needs to brake according to the road conditions and respond to emergencies. Therefore, its braking stability determines whether it can cope with various braking operations. The caliper in the high-speed rail brake system rubs against the brake disc during use, and the friction will generate heat. The heat will affect the friction between the caliper and the brake disc, and will also reduce the performance and service life of the caliper and the brake disc. Most of the calipers used in common high-speed rail brake systems are not equipped with corresponding heat dissipation structures, resulting in only natural heat dissipation. The heat dissipation effect is poor, and the brake disc cannot be quickly and stably reduced. The problem of a long braking distance may occur during the subsequent emergency braking process, and some dangerous situations may occur.

[0003] In summary, the calipers used in the high-speed rail brake system without an active heat dissipation structure have some problems in use, so it is hoped to propose a new structure to solve the above technical problems. Utility Model Content
