100, brake drum body 100 in figure with shoe brake including for the connection end 101 being connected with wheel hub 200 and for (not showing
Go out) coordinate braking circumferential part 102；Wheel hub 200 is provided with positioning table 201 and ring flange 202, and positioning table 201 is located at ring flange
202 side.The installation positioning of brake drum is engaged by the endoporus for connecting end 101 with the positioning table 201 of wheel hub 200.It is this kind of
The structure of location fit, its drawback is larger for the connection stress concentration of end 101, makes connection end 101 near braking circumferential part 102
Side (connect end 101 inner side) bear larger tension, while making connection end 101 away from braking circumferential part 102
Side (connect end 101 outside) bear larger compression, be issued in heavily loaded, severe mountain area, mining area road conditions environment
During the limiting range of stress, cracked from the inner side of connection end 101 and extend to outside, the failure that breaks off the base finally occur.
Utility model content
Technical problem to be solved in the utility model is：A kind of brake drum is provided, dispersion connects the stress concentration of end,
Release tension, eliminates compression, enhancing connection end rigidity, to solve the technical problem that brake drum breaks off the base.
In order to solve the above technical problems, the technical solution of the utility model is：Brake drum, including brake drum body, it is described
Brake drum body includes braking circumferential part and the connection end being attached thereto, and the connection end is provided with what is protruded axially outward
Annular boss, the annular boss has positioning inner peripheral surface.
Improved as one kind, the connection end includes mounting flange.
Improved as one kind, the outer surface of the annular boss is provided with loss of weight radiating groove.
As a further improvement, the loss of weight radiating groove has multiple, is formed between the two neighboring loss of weight radiating groove
Reinforcement.
As a further improvement, multiple loss of weight radiating groove array distributions are on the annular boss.
Improved as one kind, the annular boss is provided with breach, the bearing of trend of the breach and the annular boss
Unanimously.
As a further improvement, the breach has multiple.
As a further improvement, multiple breach array distributions are on the annular boss.
As a further improvement, the brake drum body is wholely set with the annular boss.
After employing above-mentioned technical proposal, the beneficial effects of the utility model are：Because the connection end of brake drum is provided with
The annular boss for protruding axially outward, the annular boss has positioning inner peripheral surface, thus can determining by annular boss
Position inner peripheral surface is engaged with the ring flange of wheel hub and is positioned, and during braking, the annular boss can offset brake force to brake drum
The moment of flexure that body is produced, so as to disperse to connect the stress concentration of end, discharges tension, eliminates compression, enhancing connection end
Rigidity, solves brake drum and breaks off the base failure.The brake drum that the utility model is provided, has disperseed to connect the stress concentration of end, release
Tension, eliminates compression, and enhancing connection end rigidity solves brake drum and breaks off the base failure.
Because the outer surface of the annular boss is provided with loss of weight radiating groove, can effectively reduce the weight of brake drum and be beneficial to
Radiating, can be used as locating and machining benchmark.
Because the loss of weight radiating groove has multiple, reinforcement is formed between the two neighboring loss of weight radiating groove so that system
The structure for moving drum is more reasonable, improves the intensity of brake drum.
Because the annular boss is provided with breach, the breach is consistent with the bearing of trend of the annular boss, thus
The weight of brake drum can be effectively reduced, while beneficial to radiating.
Because the brake drum body and the annular boss are wholely set, thus facilitate manufacture.
