Description
Technical field
The present invention relates to automobile-used braking technology field, be specifically related to a kind of automobile-used brake shoe structure of heavy-load type.
Background technique
Brake shoe belongs to the important component part of brake shoe assembly, and brake shoe assembly and brake disc assembling form brake assembly, is cover braking safe parts of service brake and parking braking.The automobile-used brake shoe of heavy-load type as shown in Figure 1 and Figure 2, by width be the steel plate of L after punching press again bending form semilune, the both sides of brake shoe left end are reamed a right-angled trapezium 1 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 1, the width W of brake shoe is 40mm, and the width W 1 of brake shoe left end is 29mm.Brake shoe assembly as shown in Figure 3, Figure 4, formed by brake shoe, friction plate 3, the braking tendons of beef, mutton or pork 4, central sleeve 5, brake axle cushion block 6, friction plate 3 is bonded in the outside of brake shoe, the braking tendons of beef, mutton or pork 4 are welded on the inboard of brake shoe, central sleeve 5 is welded on the left end of brake shoe and the braking tendons of beef, mutton or pork 4, brake axle cushion block 6 is welded on the right-hand member of brake shoe and the braking tendons of beef, mutton or pork 4, and the width of central sleeve 5 is 29mm.
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.
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, the automobile-used brake shoe of a kind of heavy-load type provided by the invention, 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 links to each other 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 50mm, 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 at described 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) 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 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 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 present invention have simple in structure, design cleverly characteristics, improved sensitivity and the braking moment of brake shoe, saved simultaneously the energy, simplified technique.
