Description
Technical field
The utility model relates to one kind to widen braking iron heel, belong to automobile brake parts technical field.
Background technique
Braking iron heel refers to the effect by brake cam or push rod and is pushed to outer expansion compacting brake and heaves braking action
Accessory, be installed on brake rim, be one of breaking piece crucial in brake system of car.Brake iron heel shape such as half a month
Shape, the semi-moon shaped braking iron heel of two panels props up braking iron heel and rubs brake just outer under the action of wheel cylinder when touching on the brake
The inner wall of vehicle drum plays the role of slowing down or stopping.Hinge hole and brake hole on existing brake-shoe are in use
Continuous abrasion, and since hinge hole is the component for connecting two brake-shoes, it is constantly using, is being easy for splitting over time
Line.
Summary of the invention
Utility model aims to solve the shortcomings of the prior art, it is simple to provide a kind of structure, easy to use
Reliably, structural strength is high, can cooperate well with brake block, prolong the service life, increase brake control power, improve safety
Widen braking iron heel.
The purpose of this utility model is completed by following technical solution, and one kind widening braking iron heel, it is by wide cut
Arc steel plate panel and two it is adjacent and be arranged vertically on steel disc panel intrados middle position arc gussets weldering even form,
The big R semi arch end edge of the one of the arc gusset is welded with the axle sleeve of full packet form, the planar ends of another small R by central shaft hole
Pin half slot is provided on side；Offered on the steel disc panel each two rows around be located on the outside of two arc gussets and
The brake film perforation of Parallel Symmetric is welded with the connecting column that at least one is arranged in the neighbouring small end R between the arc gusset
Pin.
As preferred: two outer end of axle sleeve of the big R semi arch end edge is connected to weldering and is connected on respective side arc gusset
Evagination stiffening ring；And the pin half slot at small R is located at weldering on the inside of respective arc gusset and connects and add the reinforcement block of pin connection,
One end face of steel disc panel is on planar end surface and the arc gusset that is recessed on the inside of axle sleeve；Other end is intermediate planar end surface
Connect with two sides inclined-plane, intermediate planar end surface therein and reinforcement block weldering connect.
The utility model belongs to improvements over the prior art, it has structure simple, easy to use and reliable, structural strength
Height, the features such as capable of cooperating well with brake block, prolong the service life, increase brake control power, improve safety.
Detailed description of the invention
Fig. 1 is the side structure schematic view of the utility model.
Fig. 2 is the top view in Fig. 1.
Specific embodiment
The utility model is described in detail below in conjunction with attached drawing: Fig. 1, shown in 2, one kind described in the utility model
Widen braking iron heel, it is adjacent by the arc steel plate panel 1 and two of wide cut and is arranged vertically within steel disc panel intrados interposition
The weldering of arc gusset 2 set even forms, and the one of the arc gusset 2 is big, and R semi arch end edge 3 is welded with full packet by central shaft hole
The axle sleeve 4 of form is provided with pin half slot 6 in the plane end edge 5 of another small R；Left and right is offered on the steel disc panel 1
Each two rows are located on the outside of two arc gussets and the brake film perforation 7 of Parallel Symmetric, be welded between the arc gusset 2 to
Few one is arranged in the connection pin 8 of neighbouring small R flat end 5.
As shown in the figure, 4 liang of outer ends of axle sleeve of the big R semi arch end edge 3 are connected to weldering and are connected in respective side arc gusset 2
On evagination stiffening ring 9；And the pin half slot 6 at small R is located at weldering on the inside of respective arc gusset 2 and connects and pin 10 is added to connect
Reinforcement block 11,1 one end face of steel disc panel are planar end surface 12 and are recessed on the arc gusset 2 of 4 inside of axle sleeve；The other end
Face is that intermediate planar end surface 13 connects with two sides inclined-plane 14, and intermediate planar end surface 13 therein connects with the reinforcement block 11 weldering.
The utility model is increased brake area, increases brake control power, improved safety using the panel widened；Increase
Connection reinforcement block at small R, while preventing the excessive caused gusset deformation of brake force from increasing with abrasion；Roller shaft at big R
Place is welded with outer ring, prevents from increasing in the abrasion in braking process between roller shaft and axle sleeve.
