example 1
[0065] The following describes Example 1 according to the present invention, and Example 1 of the brake plate of the present invention is generally as follows Figure 1-3 As shown, the brake plate consists of two pieces of elastic friction material blocks made of short fiber reinforced polymer, three pieces of rigid friction material blocks made of sintered metal material and 45-gauge steel that define the receiving groove support structure. Such as figure 1 As shown, the first and rigid friction material blocks are vertically stacked alternately and two of the rigid friction material blocks are located at the uppermost side and the lowermost side respectively. Such as figure 2 As shown, the laminated structure of the first and rigid friction material blocks is secured together by a plurality of longitudinally disposed fastening studs and to the support structure, which also has a plurality of substantially horizontally disposed reinforcing bolts The laminated structure is...

Abstract
The invention provides a brake plate of a train speed reducer. The brake plate defines a friction braking surface pressed against the surface of a train wheel, and comprises at least one elastic friction material block, at least one rigid friction material block and a supporting structure, wherein the at least one elastic friction material block and the at least one rigid friction material block are laminated together in a laminating direction to form a laminated structure; the laminated structure defines a laminated side face which is parallel to the laminating direction and constitutes a part of or the entire friction braking surface; the elastic friction block and the rigid friction block are exposed out of the laminated side face; and the supporting structure comprises a fastener for fastening the laminated structure on the supporting structure. The invention also provides a method for manufacturing the brake plate and a train speed reducer having the brake plate.
Description
technical field [0001] The invention relates to a brake plate of a train reducer and a method for manufacturing the brake plate of a train reducer. The invention also relates to a train speed reducer with the brake plate. Background technique [0002] Trains (mainly freight cars) are disassembled into individual carriages in the marshalling yard and reassembled according to their destinations. The carriages going in the same direction are compiled into the same track and connected in parallel to form a row. The dismantled car slides down freely from the peak of the marshalling station under the action of gravity, enters the pre-set track, and hangs with other cars in the same direction. In order to avoid damage to the train caused by overspeeding, it is necessary to control the speed of the vehicle during the exile process. Usually, the connecting speed of the train needs to be less than 5 km / h. The function of the reducer is to slow down the speeding car so that it can b...
