Description
Technical field
The invention belongs to brake system of car technical field, more particularly to a kind of brake drum.
Background technology
Brakes is one of important composition system of automobile, at present, widely used in truck field
It is using traditional monoblock cast drum brake.At this stage, typical drum brake includes brake drum and shoe brake, system
Dynamic shoe plate can be contacted with the medial surface of brake drum.Brake drum in vehicle traveling process be in rotary state, when need brake
When, shoe brake presses under the action of the braking force on brake drum, utilizes and the frictional resistance between brake drum, so that row
The car deceleration sailed or parking, to ensure traffic safety.
Brake drum is mounted by means of bolts on wheel hub.As shown in figure 1, existing brake drum includes brake drum body
100, brake drum body 100 includes the connection end 101 for being connected with wheel hub 200 and for (not showing in figure with shoe brake
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 of connection 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, crack from the inner side of connection end 101 and extend to outside, the failure that breaks off the base finally occur.
The content of the invention
The technical problem to be solved is：A kind of brake drum, the stress concentration of dispersion connection end, release are provided
Tension, eliminates compression, strengthens connection end rigidity, to solve the technical problem that brake drum breaks off the base.
To solve above-mentioned technical problem, the technical scheme is that：Brake drum, including brake drum body, the braking
Drum body includes braking circumferential part and the connection end being attached thereto, and the connection end is provided with the annular for protruding axially outward
Boss, the annular boss has positioning inner peripheral surface.
Used as a kind of improvement, the connection end includes mounting flange.
Used as a kind of improvement, the outer surface of the annular boss is provided with loss of weight radiating groove.
Used as further improvement, the loss of weight radiating groove has multiple, is formed between the two neighboring loss of weight radiating groove
Reinforcement.
Used as further improvement, multiple loss of weight radiating groove array distributions are on the annular boss.
Used as a kind of improvement, the annular boss is provided with breach, the bearing of trend of the breach and the annular boss
Unanimously.
Used as further improvement, the breach has multiple.
Used as further improvement, multiple breach array distributions are on the annular boss.
Used as further improvement, the brake drum body is wholely set with the annular boss.
After employing above-mentioned technical proposal, the invention has the beneficial effects as follows：Because the connection end of brake drum is provided with along axle
To outwardly annular boss, the annular boss has positioning inner peripheral surface, thus can pass through in the positioning of annular boss
Side face 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 body
The moment of flexure of generation, so as to disperse to connect the stress concentration of end, discharges tension, eliminates compression, strengthens connection end rigidity,
Solve brake drum to break off the base failure.The brake drum that the present invention is provided, has disperseed to connect the stress concentration of end, discharges tension, disappears
Except compression, strengthen connection end rigidity, solve brake drum and break 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, between the two neighboring loss of weight radiating groove reinforcement is formed 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.
