Embodiment Construction

[0032] figure 1 It is a structural schematic diagram of Embodiment 1 of the brake shoe protector of the present invention, as figure 1 As shown, the brake shoe protector of this embodiment includes: two grinders 111 and a mounting plate 112 .

[0033] The mounting plate 112 is fixedly arranged on the back of the brake shoe 21, and the two ends of the mounting plate 112 extend beyond the upper and lower ends of the brake shoe 21. One end is fixed on the end of the mounting plate 112 , and the inner surface of each grinder 111 is in contact with the wheel tread 3 .

[0034] The grinder 111 is used to remove debris and foreign matter from the wheel tread 3 . Grinder 111 can adopt the same material as the working surface of brake shoe 21, which not only makes the grinder 111 good in wear resistance, long in life, but also lighter in weight, saves time and effort when replacing, and reduces labor intensity. The working surface of the brake shoe 21 refers to the surface that the ...

Abstract

The invention provides a brake shoe protector and a railway vehicle brake system. The brake shoe protector provided by the invention comprises two grinding bodies and a mounting plate which is fixedly arranged on the back face of a brake shoe. The two ends of the mounting plate extend out of the upper and lower ends of the brake shoe and fix the two grinding bodies to the upper and lower ends of the mounting plate. The inner surface of each grinding body makes contact with a wheel tread. According to the brake shoe protector and the railway vehicle brake system, fragments and foreign bodies on the wheel tread are removed through the grinding bodies of the brake shoe protector, micro protrusions are prevented from generating on the wheel tread, abnormal abrasion to the brake shoe is relieved, the service life of the brake shoe is prolonged, and the maintenance cost of a railway vehicle is lowered.

Description

technical field [0001] The invention relates to vehicle braking technology, in particular to a brake shoe protector and a railway vehicle braking system. Background technique [0002] At present, the main freight car bogies in China are k2 and k6 bogies, which are suitable for the application and development of heavy-haul railways. Both types of bogies adopt brake shoe wheel tread braking device, which has superior performance and lower cost. [0003] When the brake shoe wheel tread is used for braking, the brake shoe directly contacts and rubs against the high-speed rotating wheel tread, and the friction causes wear on the working surface of the brake shoe. When small hard foreign matter (gravel, metal chips, etc.) The local abnormal wear of the brake shoe will aggravate the wear of the brake shoe, which will not only reduce the service life of the brake shoe, but also reduce the contact surface between the brake shoe and the wheel tread, thereby affecting the braking dis...
