Abstract
The invention relates to an on-line detection forced air-cooled brake drum. In order to reduce the high temperature in a brake drum and effectively brake, a traditional van mostly uses a self-remodeled water spray device to spray water on and cool the brake drum, thereby not only the weight of the vehicle is increased and not standard, but also the device cannot be used in cold areas because of freezing and the organism fails to work by accident because of the high temperature caused in braking, so the events of traffic accidents caused by brake failure happen more than once. An on-line detection forced air-cooled brake drum comprises the brake drum; an air inlet is arranged on the brake drum; a radiating hole of a spoke of the brake drum is also provided with an air-collective cover; a brake camshaft which is connected with the brake drum is also provided with a temperature sensor; and a brake shoe brake camshaft in the brake drum is provided with a position sensor. The invention can quickly remove the heat produced in the brake drum, achieve the safety, reliable, effective and durable use of the brake drum and a brake shoe, prolong the service life, and reduce the use cost.
Description

Five, embodiment
The present invention is described in detail below in conjunction with the drawings and specific embodiments.
The present invention includes brake drum 1, brake drum is provided with intake grill 2, intake grill 2 is an equidimension, equidistantly distribute on the brake drum and with spoke on vent hole inside and outside link, also be provided with wind-collection cover 3 on the vent hole of the spoke of brake drum 1, the air guide hole of wind-collection cover 3 is provided with about dividing, the brake camshaft that brake drum 1 connects is provided with temperature transducer 4, brake shoe brake camshaft in the brake drum is provided with position transducer 5, temperature transducer 4 is connected with thermocouple sensor and junction compensator 7 access voltage amplifiers 8 in parallel, the output terminal of voltage amplifier 8 is connected with voltage comparator 9 with thermometric, and thermometric is connected with triode 10 with voltage comparator 9 output terminals.Position transducer 5 is connected with relay 12, relay 12 is connected successively with amplifier 13, voltage comparator 14, light emitting diode 15 and alarm 16, described wind-collection cover 4 usefulness leaf springs are stuck on the vent hole of spoke, and contact A and contact B are arranged in the described relay 12.
On the inclined-plane of brake drum, process 5 equidistant holes referring to Fig. 1-Fig. 8, on the intake grill 2 of brake drum spoke and brake drum 1 centering, wind-collection cover 3 is installed, in vehicle traveling process, extraneous natural wind is blown in the brake drum through wind-collection cover 3, thereby reaches the purpose to brake shoe and brake drum cooling.On top, the brake camshaft outside temperature transducer 4 is installed, mounting point, side top sensor 5 within it, installation and control plate on the instrument panel of operator cabin, buzzer is arranged, the maximum or minimum controlling alarm gap of brake drum that controlling alarm temperature that the prompting temperature transducer detects and position transducer detect and brake shoe on the control panel.
When the highest control temperature that the temperature of braking automobile hoof is higher than that system is provided with, buzzer in the operator's cab begins to report to the police, the temperature of prompting driver brake shoe is too high, and this moment, the driver was not if stop to the brake shoe cooling, and brake shoe will reduce its braking ability because temperature is too high.Automobile is after long-time using process, in its parking, apply the brakes hoof repeatedly all in the moderating process, brake shoe is after long-time and automobile brake drum rubbing contact, the braking gap of itself and brake drum can increase with the mileage of the driving of automobile and strengthens, when the position transducer of installing on top, the brake camshaft outside is checked through distance between brake shoe and the brake drum greater than the minimal security braking gap, the buzzer that is installed in the operator cabin will send alarm signal, the prompting driver tackles brake shoe and changes or keep in repair, thereby has reduced the security incident that causes because of brake failure in the running process.
Control principle referring to Fig. 9-Figure 10 brake drum temperature control system: thermocouple sensor 6 and AD590 junction compensator 7 change the temperature signal of brake drum into voltage signal, this voltage signal and brake drum temperature signal linear proportional relationship in the measured temperature scope changes, sensor output voltage raises when being the temperature rising, the sensor output voltage signal amplifies the back through voltage amplifier 8 and imports thermometric make comparisons with reference voltage with voltage comparator 9 (magnitude of voltage after the reference voltage setting value is the corresponding amplification of alarm temperature), if temperature is higher than setting value, then amplifier output voltage is than reference voltage level height, comparator output high level makes triode 10 conductings, alarm 11, the transistor circuit conducting realizes reporting to the police.
Working principle referring to Figure 11 brake drum and brake shoe clearance detecting system: when not braking, relay combines with the A contact, angular displacement sensor changes the angular signal of cam into voltage signal passes to amplifier 13, the linear inversely prroportional relationship in gap between voltage signal after the amplification and Brake shoe lining and the brake drum changes, be the gap when reducing sensor output voltage raise, voltage signal after the amplification compares (the reference voltage setting value is the magnitude of voltage after the corresponding amplification of minimum clearance) with reference voltage by voltage comparator 14, if the gap is less than setting value, then corresponding amplifying signal is higher than setting value, comparator output high level makes the triode conducting, alarm 16, light emitting diode 15 circuit turn-ons are realized reporting to the police.During braking, relay combines with the B contact, angular displacement sensor changes the angular signal of cam into voltage signal passes to amplifier 13, gap between angular signal reflection brake drum and the brake shoe friction plate, the linear proportional relationship in gap between this voltage signal and Brake shoe lining and the brake drum changes, be the gap when increasing sensor output voltage raise, the sensor output voltage signal is input to voltage comparator make comparisons with reference voltage (magnitude of voltage after the reference voltage setting value is the corresponding amplification in maximal clearance) after amplifier 13 amplifies.If the gap is higher than setting value, then amplifier output voltage is than reference voltage level height, and comparator output high level makes the triode conducting, and alarm 16, circuit of LED conducting realize reporting to the police.
