Main Problems is: the width W 3 of (1) central sleeve 4 equates with the width W 1 of brake shoe 1 left end, when central sleeve 4 is welded with brake shoe 1, is prone to the overlap knurl, 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 to be wanted by satisfying the market, exposes the problem that sensitivity is poor, braking moment is inadequate.
Summary of the invention
The present invention is intended to improve sensitivity and the braking moment of brake shoe, and energy saving is simplified technique simultaneously.
For this reason, a kind of agricultural type tricycle braking hoof assembly provided by the invention, comprise brake shoe, the braking tendons of beef, mutton or pork, friction plate, central sleeve and brake axle cushion block, described brake shoe is to be the steel plate of the W semilune that forms of bending again after punching press by width, friction plate and the braking tendons of beef, mutton or pork also are semilune, friction plate is bonded in the outside of brake shoe, the braking tendons of beef, mutton or pork are welded on the inboard of brake shoe, central sleeve is welded on the left end of brake shoe and the braking tendons of beef, mutton or pork, the brake axle cushion block is welded on the right-hand member of brake shoe and the braking tendons of beef, mutton or pork, 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 links to each other with the middle part of brake shoe by the hypotenuse of right-angled trapezium, key is: 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 3 of described central sleeve is greater than the width W 1 of brake shoe left end, and the width W 4 of brake axle cushion block equates with the width W 2 of brake shoe right-hand member.
Be preferably, the width W at described brake shoe middle part and the width of friction plate are 45mm, and the width W 3 of central sleeve is 29mm, and the width W 1 of brake shoe left end is 27mm, and the width W 2 of brake shoe right-hand member and the width W 4 of brake axle cushion block are 40mm.
Further, 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 at brake shoe middle part is
The width W 1 of brake shoe left end is
The present invention 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 to occur 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 of central sleeve when brake shoe welds, avoid the two ends of brake shoe above the phenomenon generation of central sleeve end face; In the situation that does 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 present invention have simple in structure, design cleverly characteristics, improved sensitivity and the braking moment of brake shoe assembly, saved simultaneously the energy, simplified technique.
