Main Problems is: the width of (1) central sleeve 5 equates with the width W 1 of brake shoe left end, when central sleeve 5 is welded with brake shoe, is prone to overlap, affects next step assembling and use, need to carry out technique for grinding; (2) along with the user to improving constantly that brake shoe assembly braking ability and carrying capacity require, standing state can not need by satisfying the market, exposes the problem that sensitivity is poor, braking moment is inadequate.
The model utility content
The utility model is intended to improve sensitivity and the braking moment of brake shoe, and energy saving, simplify technique simultaneously.
for this reason, a kind of agricultural type tricycle braking shoe plate that the utility model provides, by width be the steel plate of W after punching press again bending form semilune, the both sides of described brake shoe left end are reamed a right-angled trapezium symmetrically, make the width W 1 of brake shoe left end less than the width W of bending steel plate, and the left end of brake shoe is connected with the middle part of brake shoe by the hypotenuse of right-angled trapezium, it is characterized in that: the both sides of described brake shoe right-hand member are reamed a right-angled triangle symmetrically, make the width W 2 of brake shoe right-hand member less than the width W of bending steel plate, the hypotenuse of described right-angled triangle has consisted of the outer side of brake shoe right-hand member, the width W at described brake shoe middle part is 45mm, and the width W 1 of brake shoe left end is 27mm, and the width W 2 of brake shoe right-hand member is 40mm, and the length of run L of brake shoe is 286.6mm, and the length of run L2 of brake shoe right-hand member is 40mm.
Be preferably, the width W in the middle part of described brake shoe is
The width W 1 of brake shoe left end is
The utlity model has following improvement and beneficial effect:
(1) by increasing the reduction of brake shoe left end right-angled trapezium, the left end of brake shoe and central sleeve welding, the left end width W 1 of brake shoe is reduced to 27mm, width 29mm less than central sleeve, 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 have obtained effectively saving.
(2) 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, improve sensitivity; Simultaneously, the right-hand member width W 2 of brake shoe is identical with former brake shoe, and the size constancy with the brake axle cushion block of brake shoe right-hand member welding not increasing under the raw-material prerequisite of brake axle cushion block, is improved sensitivity.
In sum: the utlity model has simple in structure, design characteristics cleverly, improved sensitivity and the braking moment of brake shoe, saved simultaneously the energy, simplified technique.
