Description
Technical field
The present invention relates to auto parts and components field, and in particular to a kind of retarder oil radiator.
Background technology
On January 5th, 2012, Ministry of Industry and Information put into effect《Strengthen on further improving large and medium bus truck headache technical performance
Vehicle management and the notice of registration management work》, it is desirable to " lorry of Dangerous Goods Transport car, gross mass more than 12 tons fills
Standby retarder or other complemental brake systems ", while new edition《Motor vehicle safe and technical specification》(GB7258) will be bright in
Really lorry installation retarder or other complemental brake systems of the regulation more than 12 tons；Auto brake system be in vehicle safety travel most
One of important system, with the improvement of engine technology developments and road conditions, travel speed and the single operation of automobile away from
From all having a great development, traveling kinetic energy is greatly improved, so that traditional friction disk type brake apparatus is increasingly
Long-time, the need of work of high intensity are not adapted to.Due to frequently or for a long time using running brake, there is friction plate mistake
The brake efficiency heat fading phenomenon of heat, causes brake fade, threatens traffic safety when serious.Vehicle is also made because frequently changing
Dynamic shoe plate and tire cause the increase of cost of transportation.In order to solve this problem, the various vehicle auxiliary braking systems that arise at the historic moment
System develops rapidly, and Retarder is exactly one of which.
It is difficult in order to solve the problems, such as to slow down in train short distance Retarder occur earliest.Hereafter, Retarder quilt
With on truck combination, finding its good auxiliary braking effect.Current Retarder is applied to heavy type more and more
On cargo vehicle and Large and medium buses.With the development of its application, there is the company of many production Retarders.Compare
Famous Retarder manufacturer has German Fu Yite (VOITH) company, French Tai Erma (TELMA) company, AM General public
Department, Japanese TBK companies etc..At present, the Retarder research and development in China have had certain development, and are had started in part company
Development test.Retarder mounting means is generally divided into and transmission tandem shafts and and even two kinds.During series winding can before speed changer,
After install；If taking and connecting, retarder and speed changer are integrally formed to install.When retarder works, compressed air
Enter fuel reserve tank through magnetic valve, the transmission oil in fuel reserve tank is pressed into retarder through oil circuit, retarder is started working.Rotor
Fluid is driven to rotate about the axis；Meanwhile fluid moves along direction blade, get rid of to stator.Stator vane produces reaction to fluid,
Fluid outflow stator is gone back to again carrys out impact rotor, thus forms the moment of resistance to rotor, hinders the rotation of rotor, so as to realize
To the decelerating effect of vehicle.Working solution makes inlet and outlet form pressure differential, oil circulation flowing in motion process, and is handed over by heat
Row heat exchange during parallel operation, heat exchanger now need strong heat exchange performance, can meet needs during vehicle traveling；
Show from the application study of newest Retarder, jointly controlled using engine braking, exhaust brake, Retarder
During braking, effect is even more ideal.Engine braking has good slowing effect at the low rotational speed, as rotating speed raises, exhaust system
Dynamic, retarder braking starts to intervene, and severity of braking is gradually increased.So it is used cooperatively, vehicle steadily descending can be made, improve vapour
The security of car descending.Shenzhen's public transport (group) Co., Ltd was once carried out to score to affiliated 3 route public transit vehicle
Analysis.No. 3 circuits have air-conditioned bus 20, equipped with B300R automatic transmission, there is Retarder；Common bus 17, equipment
AT545 automatic transmission, no Retarder.Two kinds of cars are EQ1141G chassis.By comparative analysis, common bus changes
Piece, 1.73 and 2.03 times that drum amount is air-conditioned bus respectively are changed, report 1.93 times that frequency is air-conditioned bus for repairment.Fluid power as can be seen here
The using effect of retarder is quite preferable.Therefore vehicle safety is improved, due to driving when reducing ramp driving
The security incident that brake-fade triggers, automobile average overall travel speed in descending is improved, in flat pavement running, can be compared
Relatively easily control to adjust speed and keep vehicle headway；Reduce frequently slow and braking, improve the comfortableness of vehicle
And yarage, the fatigue strength of driver is greatly reduced, reduces brake oil；Improve the economy of vehicle transport
Property, economic benefit is clearly；China's heavy truck cumulative production more than 200 ten thousand in 2011, current research exploitation are matched
Heat-exchanger products prospect it is boundless, it is international, domestic market is guaranteed.
In existing retarder oil radiator, its each heat radiation chip is plate armature, therefore it radiates
Effect is not excellent enough, does not reach the requirement used.
