Abstract
The utility model discloses a stamping and welding horizontal-moving brake shoe used for a drum brake. The brake shoe comprises an arc-shaped steel plate and a rib plate, wherein the outer edge of the rib plate is fixed to the inner wall of the arc-shaped steel plate, and the inner side and the outer side of the rib plate are concentric arcs. The brake shoe is characterized in that a capsule-shaped hole is formed in one end of the rib plate. According to the stamping and welding horizontal-moving brake shoe used for the drum brake, due to the fact that a round hole in the end of the brake shoe is changed into the capsule-shaped hole, when the brake shoe rotates along a supporting hinge pin inserted in the capsule-shaped hole, the brake shoe moves backward at the same time, the brake shoe and a friction lining on the outer side of the brake shoe can horizontally move towards the inner wall of the brake drum, and thus the braking performance is improved; due to the fact that the stamping and welding technology is adopted for the arc-shaped steel plate and the rib plate, the weight is reduced, and production cost is reduced.
Description
Technical field
The utility model relates to the improvement of brake shoe for a kind of drum brake, specifically a kind of in brake process friction facing can all synchronize the drum brake of contact with brake drum inwall and weld translation brake shoe with rushing.
Background technique
The drum brake using on automobile at present, comprise that braking bottom board, brake drum, brake shoe, friction facing, brake cam, return spring, limit spring, support bearing pin form, brake shoe comprises curved plate and gusset, one end at gusset is provided with circular hole, support in the circular hole of bearing pin insertion gusset one end, and be fixed on braking bottom board, curved plate and gusset are cast into an integral body.The deficiency of the brake shoe of this drum brake is: the one, because one end of gusset is circular hole, when the other end of gusset outwards supports, can only outside supporting pin is axial, rotate, make the friction plate in the outside of brake shoe from free end to circular hole end, touch successively the inwall of brake drum, during to circular hole end place, and between the inwall of brake drum, have all the time a certain interval, this has just caused differing of the friction facing degree of wear, not only make reduce the working life of friction facing, and caused the reduction of stopping power; The 2nd, owing to being that casting forms, so weight is large, cost of production is high.
Summary of the invention
The purpose of this utility model is to provide the relative brake drum inwall of a kind of brake shoe translation contact, thereby make the lining surface in brake shoe outside touch the inwall of brake drum simultaneously, thereby can improve braking quality and be the punching weldering translation brake shoe for drum brake that punching weldering forms.
In order to reach above object, the technological scheme that the utility model adopts is: punching weldering translation brake shoe for this drum brake, comprise curved plate and gusset, gusset outer edge is fixed on the inwall of curved plate, the inside and outside edge of gusset is concentric arcs, it is characterized in that: one end of described gusset is provided with capsule shape hole, during use, supporting shaft inserts in capsule shape hole, and is fixed on braking bottom board.
The utility model is also implemented by following measure: the described axis in capsule shape hole and the angle of the radius of arc of gusset are 48-65 degree, the waist width in capsule shape hole is consistent with the diameter of the support bearing pin of insertion, and the length in capsule shape hole is 1.3 times of capsule shape hole waist width.
Described curved plate and gusset adopt steel plate punched to form, and are welded and fixed and are integrated.
The beneficial effects of the utility model are: compare with the brake shoe that current drum brake uses, because the circular hole of brake shoe end changes capsule shape hole into, when the support bearing pin of brake shoe in inserting capsule shape hole rotates, move backward simultaneously, so, the friction facing in brake shoe and outside thereof can be towards the inwall translation of brake drum, therefore improved braking ability; Due to curved plate and gusset employing pressing and jointing technique, so alleviated weight, reduced cost of production.
Accompanying drawing explanation
Fig. 1 is structure schematic top plan view of the present utility model.
In figure: 1, curved plate; 2, gusset; 3, capsule shape hole; 4, angle.
Embodiment
With reference to Fig. 1, make the utility model.Punching weldering translation brake shoe for this drum brake, comprise curved plate 1 and gusset 2, gusset 2 outer edges are fixed on the inwall of curved plate 1, in gusset 2, outer edge is concentric arcs, it is characterized in that: one end of described gusset 2 is provided with capsule shape hole 3, during use, supporting shaft inserts in capsule shape hole 3, and be fixed on braking bottom board, when the other end of gusset 2 outwards supports, gusset 2 both rotated outside supporting pin is axial, along supporting shaft, pass backward again, cause the lining surface in outside of brake shoe simultaneously towards the inwall translation of brake drum, touch the inwall of brake drum simultaneously.
As improvement of the present utility model: the angle 4 of the axis in described capsule shape hole 3 and the radius of arc of gusset 2 is 48-65 degree, the waist width in capsule shape hole 3 is consistent with the diameter of the support bearing pin of insertion, and the length in capsule shape hole 3 is 1.3 times of capsule shape hole 3 waist width.
Described curved plate 1 and gusset 2 adopts steel plate puncheds to form, and is welded and fixed and is integrated.
