Description
Technical field
The utility model belongs to auto parts and components detection device field, and in particular to a kind of measurement formula break drum temperature indirectly
Monitoring and alarm device.
Background technique
The braking ability of truck drum brake, it is on a declining curve with the rising of break drum temperature, in the long descending work of heavy duty
Condition, vehicle keep high power to brake for a long time, easily lead to brake braking force decline until can not stop, there are larger safety is hidden
Suffer from.In practical application, user installs brake drum liquid distribution additional to vehicle to realize brake drum cooling purpose, but this measure is in winter meeting
Lead to icy road, and does not meet traffic law；User, which generally takes, at present installs complemental brake system (such as Retarder additional
Deng) to reduce brake power, to make break drum temperature maintain reduced levels, but driver still can be to vehicle
Security risk feels worry, therefore need to install break drum temperature monitoring device additional.
Since brake drum rotates in vehicle travel process, at present there are mainly three types of break drum temperature monitoring devices: 1, using
Contact type temperature sensor, and twisted wire is prevented using capstan winch；2, using contact type temperature sensor, pass through wireless transmission/reception
Module realizes signal transmission；3, break drum temperature, such as infrared temperature sensor are measured using noncontacting proximity sensor；Above-mentioned three kinds
Scheme haves the shortcomings that at high cost, reliability is low, is unsatisfactory for requirements of mass production.This patent purpose be to develop it is a at
This cheap and high reliablity temperature monitoring device.
Summary of the invention
The utility model in order to overcome existing for existing brake drum temperature measurement apparatus it is at high cost, reliability is low etc. asks
Topic provides one kind monitoring of measurement formula break drum temperature and alarm device indirectly.
In order to solve the above technical problems, the utility model adopts the following technical scheme that realization:
It is a kind of to measure the monitoring of formula break drum temperature and alarm device indirectly, which is characterized in that the shoe brake of vehicle to be measured
Cam rest is fixedly connected by bolt with the vertical section of the sensor stand of a L-shaped, on the horizontal segment of sensor stand
It is fixed with a screw-type temperature sensor, the temperature measuring point of screw-type temperature sensor is directed at the brake drum inner surface of vehicle to be measured
And 2 millimeters of the brake drum inner surface apart from vehicle to be measured, screw-type temperature sensor pass through harness and data processing and acquisition mould
Block connection, data processing and acquisition module are connect with the instrument system of vehicle to be measured, are realized by the instrument system of vehicle to be measured
Temperature display, monitoring and alarm procedure.Compared with prior art the beneficial effects of the present invention are:
A kind of formula break drum temperature of measurement indirectly monitoring described in the utility model and warning device pass through measurement brake drum
The temperature of the air of point of proximity, and the temperature relation between measured point and brake drum is judged by test, it can be accurate
The real time temperature of brake drum is extrapolated indirectly, provides judgment basis for driver safety driving；Described device avoid capstan winch or
The use of non-contact temperature sensor, composition component structure is simple, at low cost, produces convenient for product batch, and performance is stablized,
High reliablity.

Specific embodiment
The present invention is explained in detail with reference to the accompanying drawing:
The present invention provides a kind of formula break drum temperature of measurement indirectly monitoring and alarm devices, by measuring measured point simultaneously
And brake drum surface temperature, and compare the two variation tendency and obtain measured point temperature and brake drum surface temperature relation.Relationship ginseng
See Fig. 2, by the curve can extrapolate measured point temperature and brake drum actual temperature can approximate simulation be a piecewise function.
A kind of formula break drum temperature of measurement indirectly monitoring described in the utility model and warning device, as depicted in figs. 1 and 2
The shoe brake Cam rest 2 of vehicle to be measured is fixedly connected by bolt with the vertical section of the sensor stand 3 of a L-shaped,
The horizontal segment front of sensor stand 3 is fixed with a screw-type temperature sensor 1, the temperature measuring point of screw-type temperature sensor 1
It is directed at the brake drum inner surface of vehicle to be measured and 2 millimeters of brake drum inner surface apart from vehicle to be measured, screw-type temperature sensor 1
It being connect by harness with data processing and acquisition module, data processing and acquisition module are connect with the instrument system of vehicle to be measured,
Temperature display, monitoring and alarm procedure are realized by the instrument system of vehicle to be measured.Temperature measurement circuit schematic diagram as shown in figure 3, its
Thermometric range is 80 DEG C to 475 DEG C.Screw-type temperature sensor 1 is measured away from the sky at brake drum inner surface specific range (2mm)
Temperature degree obtains the two under different operating conditions by the data of the temperature measuring point temperature and break drum temperature that measure in testing before this
Fit correlation, and by calculate in instrument show brake drum approximate temperature.
