Problems solved by technology
[0004] The first purpose of the present invention is to provide a brake shoe system with reliable connection, heat dissipation, good friction effect and no metal fiber brake pads, so as to solve the problem of the existing brake shoe friction pads without metal fiber brake pads. Problems of falling off and inconvenience during water cooling
[0005] The second purpose of the present invention is to further provide a brake shoe system without metal fiber brake pads that does not easily produce polishing on the friction surface during friction braking, so as to solve the problem of the existing brake shoe system without metal fiber brake pads. The friction surface of the hoof is prone to polishing, resulting in a decrease in braking effect

Embodiment Construction
[0021] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0022] see figure 1 with figure 2 , a brake shoe without metal fiber brake pads, including a base 1 and a friction pad 2, the base 1 includes a bottom wall 11 and a side wall 12 connected to the bottom wall. The bottom wall and the side wall form a connection pit. The inner peripheral surface of the side wall is a slope inclined toward the outside of the connection pit. The outer peripheral surface of the side wall is a slope inclined in the same direction as the inner peripheral surface. Pinholes 13 are provided on the bottom wall. A tin block 14 accommodated in the side wall and in an exposed state is provided on the opposite side of the side wall. The bottom wall is provided with a plurality of bottom wall heat dissipation through holes 15 . The heat dissipation through hole in the bottom wall is a tapered hole with a larger diameter at the in...

The invention relates to a brake shoe with a nonmetal fiber brake pad. The brake shoe comprises a base and a friction plate. The base comprises a bottom wall and a side wall. Tin blocks are arranged on the inner circumferential face of the side wall. The friction plate comprises a friction layer, a heat isolation layer and a connecting layer, all of which are sequentially arranged. The friction layer is made of nonmetal fiber. Metal connecting ribs are arranged in the connecting layer. The two ends of the metal connecting ribs are provided with cutting edges arranged towards the bottom wall and embedded and arranged in the tin blocks in a tin welding manner. The bottom wall is provided with a plurality of bottom wall part heat dissipation through holes. The friction plate is provided witha plurality of friction plate part heat dissipation through holes. The bottom wall part heat dissipation through holes and the friction plate part heat dissipation through holes are aligned in a one-to-one correspondence manner. Friction fiber filaments with barbs are arranged in the friction layer. The barbs on the adjacent friction fiber filaments are opposite. A heat expansion and cold shrinkage avoiding gap is formed between the connecting layer and the bottom wall. The brake shoe has the beneficial effects that connecting is reliable, heat dissipation is convenient, and the friction effect is good; and the problems that a friction plate of an existing brake shoe with a nonmetal fiber brake pad is likely to fall off, and inconvenience is caused during water cooling are solved.
Description
technical field [0001] The invention relates to the technical field of friction braking, in particular to a brake shoe without metal fiber brake pads and a manufacturing method thereof. Background technique [0002] In response to market demand, the formulation of brake pads for metal-less brake shoes has been improved, and on the premise that various performance indicators do not decline, brake shoes with brake pads that use less or no metal friction materials have been developed. [0003] However, the existing brake shoe still has the following deficiencies: it is easy to disengage between the friction plate and the base; the friction plate is prone to polishing during braking, resulting in a rapid decline in braking effect; Especially when water cooling is carried out during the process, the cooling water is not easy to enter the friction surface to cool the friction plate. Contents of the invention [0004] The first purpose of the present invention is to provide a br...
