Description
Technical field：
The utility model is related to the brake field of automobile, is exactly specifically a kind of lightweight wheel hub brake drum assembly.
Background technology：
Set hub or patch hub wheel hub band brake drum assembly need to dismantle semiaxis and half in more renewal of facing renewal in the market
Shafting oil is sealed, and dismantles tedious process, more renewal of facing renewal is costly, and need to dismantle axle-shaft oil seal, and axle-shaft oil seal is needed more after removal
The axle-shaft oil seal renewed, cost increases again, adds automobile purchase user in maintaining and replacing of the later stage for friction plate
Expense.
Utility model content：
The utility model be exactly for overcome in the prior art deficiency need not dismantle the i.e. replaceable friction plate of semiaxis there is provided one kind
Wheel hub brake drum assembly.
The utility model provides following technical scheme：
A kind of lightweight wheel hub brake drum assembly, it includes wheel hub, and is coaxial therewith the brake drum of cooperation, described
Wheel hub is connected with friction on the back-plate in brake drum with being equipped with semiaxis on brake drum by one group of friction plate alignment pin
Piece, the back-plate in friction plate alignment pin side is additionally provided with the alignment pin fixation spiral shell with friction plate alignment pin formation secure fit
Bolt, it is characterised in that：It is provided with the wheel hub of alignment pin fixing bolt side and fixes spiral shell with friction plate alignment pin and alignment pin
The corresponding breach of bolt.
On the basis of above-mentioned technical proposal, there can also be technical scheme further below：
Described breach, is arc notch.
Utility model advantage：
The utility model is simple in construction, can directly be transformed on existing part, transform process simplicity, hardly increase production
Product cost, by setting breach in the corresponding position of wheel hub, the friction plate alignment pin and alignment pin in brake drum are fixed
Bolt is exposed, so that it is necessary to semiaxis on dismounting wheel hub in advance and wheel hub when overcoming more renewal of facing renewal in the prior art
Operating procedure, greatly reduce more renewal of facing renewal difficulty, reduce maintenance cost.
Brief description of the drawings：
Fig. 1 is structural representation of the present utility model.
Embodiment：
As shown in figure 1, a kind of lightweight wheel hub brake drum assembly, it includes wheel hub 1, and is coaxial therewith the braking of cooperation
Drum 2, is also equipped with the semiaxis 7 for being coaxial therewith coordinating on described wheel hub 1 and brake drum 2.
Brake(-holder) block 3a is connected with by one group of friction plate alignment pin 3 on back-plate 2a in brake drum 2, in brake(-holder) block
On be connected with friction plate 4, be additionally provided with the back-plate of the side of friction plate alignment pin 3 and friction plate alignment pin 3 formation fix
The alignment pin fixing bolt 5 of cooperation.
It is provided with and friction plate alignment pin on the wheel hub 1 of described alignment pin fixing bolt 5 Yu the side of friction plate alignment pin 3
3 and the corresponding arc notch 6 of alignment pin fixing bolt 5, pass through circle between the two ends of described arc notch 6 and wheel hub 1
Angle is excessive.Such design to set on wheel hub will not cause to decline after breach to wheel hub bulk strength.
Operation principle：
When needing more renewal of facing renewal, it is only necessary to pull down braking drum coating, then at gap position, positioning is directly unclamped
Fixing bolt is sold, friction plate alignment pin is taken after extraction out of again, you can pulled down and more renewal of facing renewal.So as to overcome in the prior art
It is necessary to remove the operating procedure of semiaxis on wheel hub and wheel hub in advance during more renewal of facing renewal, more renewal of facing renewal is greatly reduced difficult
Degree, reduces maintenance cost.
