Abstract
The utility model discloses a kind of brake drums of accurate measurement brake clearance comprising ontology, ontology are column barrel structure, are provided with counterbore on the ontology end face opposite with friction plate, 1mm~1.5mm in counterbore is protruded into the end face of friction plate.The utility model also solves the problems, such as brake clearance measurement inaccuracy by brake drum of the design with counter bore structure, neither influence brake drum craftsmanship, intensity.
Description
Technical field
The utility model belongs to vehicle brake technical field, is related to a kind of brake drum of accurate measurement brake clearance.
Background technique
Heavy-duty car generally matches drum brake or disk brake.Wherein, drum brake be by brake drum with
The cylindrical friction pair that brake bush periphery is constituted realizes braking.
For the ease of casting, the matched brake drum inner hole rubbing surface of heavy-duty car is cylindrical surface at present.After assembly, system
There are a fixed spacings with friction plate end face for dynamic drum end face.The heavy truck of matching hand regulation arm needs manually at regular intervals
Adjust the gap between brake drum and friction plate, reasonable brake clearance is to the braking ability of heavy truck and safety to Guan Chong
It wants.
Truck passes through long-term immobilization, and brake drum inner headed face can grind step, the measurement between friction plate and brake drum at this time
Gap is less than actual gap.It is elongated that gap increase will lead to chamber stroke, and the braking response time extends, and brake force reduces, safety
Property reduce.
Utility model content
(1) purpose of utility model
The purpose of this utility model is: providing a kind of brake drum of accurate measurement brake clearance, makes brake drum and friction plate
Between measurement gap be equal to actual gap.
(2) technical solution
In order to solve the above-mentioned technical problem, the utility model provides a kind of brake drum of accurate measurement brake clearance, packet
Ontology is included, ontology is column barrel structure, is provided with counterbore on the ontology end face opposite with friction plate, it is heavy that the end face of friction plate is protruded into
1mm~1.5mm in hole.
Wherein, the counterbore depth is 4.5mm~5mm, and diameter is 420mm~425mm.
Wherein, the counterbore depth is 5mm, diameter 420mm.
Wherein, counterbore bottom surface 1.5mm is protruded into the end face of the friction plate.
Wherein, it is provided with mounting hole on the brake drum other end mounting surface, ontology is installed on wheel hub by mounting hole.
Wherein, the brake drum ontology is made of gray cast iron.
Wherein, described this volume surrounding of brake drum is aluminium alloy, and liner is cast iron lining ring.
(3) beneficial effect
The brake drum that brake clearance is accurately measured provided by above-mentioned technical proposal, by designing the braking with counter bore structure
Drum, neither influence brake drum craftsmanship, intensity, while also solving the problems, such as brake clearance measurement inaccuracy.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model brake drum.
Fig. 2 is the mounting structure schematic diagram of brake drum.
Fig. 3 is the partial enlarged view of Fig. 2.
Specific embodiment
To keep the purpose of this utility model, content and advantage clearer, with reference to the accompanying drawings and examples, to this reality
It is described in further detail with novel specific embodiment.
Shown in referring to Fig.1, the present embodiment brake drum includes ontology, and ontology is column barrel structure, and ontology is opposite with friction plate
End face on be provided with counterbore, 1mm~1.5mm in counterbore is protruded into the end face of friction plate.
Wherein, counterbore depth is 4.5mm~5mm, and diameter is 420mm~425mm.
Preferably, counterbore depth is 5mm, diameter 420mm.
Counterbore bottom surface 1.5mm is protruded into the end face of friction plate.
It is provided with mounting hole on brake drum other end mounting surface, ontology is installed on wheel hub by mounting hole.
In the present embodiment, brake drum ontology is made of gray cast iron；Alternatively, this volume surrounding of brake drum is aluminium alloy, liner
For cast iron lining ring.
As can be seen from the above technical solutions, the utility model increases counterbore on brake drum, guarantees that friction plate end face is super
It counterbore end face out can be with precise measurement brake clearance under the premise of not influencing brake drum intensity.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, without deviating from the technical principle of the utility model, several improvement and deformations can also be made, these change
It also should be regarded as the protection scope of the utility model into deformation.
