Be preferably, the length of run L of described brake shoe is 286.6mm, and the length of run L2 of brake shoe right-hand member is 40mm, and the radius of curvature R of friction plate is 110mm, and the width W in the middle part of brake shoe is
The width W 1 of brake shoe left end is
The utlity model has following improvement and beneficial effect:
(1) width W 3 of assurance central sleeve is constant, by increasing the reduction of brake shoe left end right-angled trapezium, make the width W 3 of central sleeve greater than the width W 1 of brake shoe left end, can avoid brake shoe and central sleeve when welding solder skip occurs and produce overlap, the subsequent processing that affect brake shoe assembly assembles, brake shoe assembly use and remove the technique such as overlap; In addition, can also guarantee the degree of symmetry when central sleeve is welded on brake shoe, avoid the two ends of brake shoe over the phenomenon generation of central sleeve end face; In the situation that do not affect assembling and use, the steel plate raw material of making brake shoe have obtained effectively saving.
(2) width of assurance brake axle cushion block W4 is constant, by increasing the width W of brake shoe, increase accordingly the width of the friction plate that bonds together with brake shoe, thereby increased the friction area of brake shoe assembly and brake drum, thereby strengthened frictional force, improved sensitivity; Simultaneously, the right-hand member width W 2 of brake shoe is identical with former brake shoe, and is constant with the width of the brake axle cushion block W4 of brake shoe right-hand member welding, not increasing under the raw-material prerequisite of brake axle cushion block, sensitivity is improved.
In sum: the utlity model has simple in structure, design characteristics cleverly, improved sensitivity and the braking moment of brake shoe assembly, saved simultaneously the energy, simplified technique.
