Description
Technical field
The utility model relates to a kind of automotive brake field, in particular to a kind of brake with warning function.
Background technique
Drum brake is usually used in the rear service brake of automobile and the hand brake system of automobile, but the fever of drum brake compared with
Greatly, brake friction plate be easy abrasion, when friction disc wear to a certain extent when, braking gap becomes larger, braking effect be deteriorated,
It is serious to may cause safety accident, so replacement in time is needed, but in the prior art, it is not able to detect automotive brake
The device and resulting structure of abrasion, it is therefore necessary to propose new technical solution.
Summary of the invention
The purpose of the utility model is to provide a kind of detection brake wear situation, temperature variations, and have alarm
The brake of function.
The above-mentioned technical purpose of the utility model has the technical scheme that
A kind of brake with warning function, including brake drum, two brake-shoes being symmetricly set on inside brake drum,
Friction plate, wheel cylinder, reset spring, pin shaft, the connector being mounted on brake-shoe, the wheel cylinder are mounted on two systems
The top of dynamic hoof, and abutted with two brake-shoes, described two brake-shoe bottom ends are fixedly connected by pin shaft with connector, special
Sign is: the both ends of the friction plate on the brake-shoe set resistance metal block, and the resistance metal block is integrally fixed with friction plate,
And the surface of resistance metal block and the rubbing surface of friction plate form a complete curved surface, fixed resistance metal on the friction plate
The both ends of block are equipped with reserved through hole, set that there are two binding posts corresponding with reserved through hole position on the resistance metal block, described
Binding post passes through reserved through hole and is electrically connected by conducting wire and warning indicator.
Further, the bottom position of the inside brake drum is equipped with a temperature sensor, and the temperature sensor is logical
It crosses conducting wire and warning indicator is electrically connected.
Further, the temperature sensor is infrared temperature sensor, and the infrared head of the temperature sensor is vertical
In the inner wall of brake drum.
In conclusion the utility model has the following beneficial effects: 1, be mounted on friction plate by resistance metal block, electricity
Metal block is hindered with the abrasion of friction plate, the sectional area of resistance metal block tails off, and resistance becomes larger, when wearing to a certain extent,
When warning indicator detects that resistance value reaches preset value, warning indicator automatic alarm reminds user to need replacing friction plate；
2, when temperature sensor can monitor brake, temperature on brake drum prevents temperature excessively high, avoids brake wear serious, mention
High security；3, resistance metal block is mounted on the both ends position of friction plate, by comparing the resistance value of both ends resistance metal block
Size can effectively monitor friction plate it is known that friction plate on brake-shoe and inside brake drum are bonded abrasion condition
Serious eccentric wear whether occurs between brake drum, so as to adjust the relative position between friction plate and brake drum, improves braking effect
Fruit.
Detailed description of the invention

Specific embodiment
The utility model is described in further detail below in conjunction with attached drawing.
As depicted in figs. 1 and 2, a kind of brake with warning function, including brake drum 1, it is symmetricly set on brake drum 1
Two brake-shoes 2 of inside, friction plate 3, wheel cylinder 5, reset spring 6, pin shaft 7, the connector 9 being mounted on brake-shoe 2,
The wheel cylinder 5 is mounted on the top of two brake-shoes 2, and abuts with two brake-shoes 2, described two 2 bottom ends of brake-shoe
It is fixedly connected by pin shaft 7 with connector 9, the both ends of the friction plate 3 on the brake-shoe 2 are equipped with resistance metal block 4, the electricity
Resistance metal block 4 is integrally fixed with friction plate 3, and the rubbing surface of the surface of resistance metal block 4 and friction plate 3 forms one completely
Curved surface, the both ends of fixed resistance metal block 4 are equipped with reserved through hole 10 on the friction plate 3, and the resistance metal block 4 is equipped with
Two binding posts 11 corresponding with 10 position of reserved through hole, the binding post 11 pass through reserved through hole 10 and by conducting wires and alarm
Indicator 12 is electrically connected；When braking, the inner wall of the rubbing surface of the surface of resistance metal block 4 and friction plate 3 and brake drum 1 pastes
Friction is closed, brake force is generated, resistance metal block 4 is thinning as friction plate 3 is worn together, and the cross-sectional area of resistance metal block 4 becomes
Small, resistance becomes larger, and when warning indicator 12 monitors that the resistance value of any one piece of resistance metal block 4 reaches certain value, that is, rubs
When plate 3 is worn to a certain extent, alarm signal is issued, prompts to need replacing friction plate 3, meanwhile, it can compare on same friction plate 3
Two resistance metal blocks 4 resistance value, if two resistance metal blocks 4 resistance value difference it is larger, illustrate friction plate 3 and brake drum 1
Between serious eccentric wear occurs, the relative position of friction plate 3 and brake drum 1 can be adjusted in time, avoid friction plate 3 from continuing improper
Abrasion, improves the service life of brake；Bottom position inside the brake drum 1 is additionally provided with a temperature sensor 8, described
Temperature sensor 8 is electrically connected by conducting wire and warning indicator 12；The temperature sensor 8 is infrared temperature sensor, institute
Inner wall of the infrared head perpendicular to brake drum 1 of temperature sensor 8 is stated, infrared temperature sensor is a kind of non-contact temperature measuring work
Tool compares the thermometric of the brake drum 1 suitable for rotation, has many advantages, such as that thermometric is accurate, cheap, passes through temperature sensing
Device 8 monitors the temperature on brake drum 1, and when avoiding braking, temperature is excessively high, leads to brake fade.
This specific embodiment is only the explanation to the utility model, is not limitations of the present invention, ability
Field technique personnel can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but
As long as all by the protection of Patent Law in the scope of the claims of the utility model.
