Description
Technical field
The utility model relates to a kind of hydraulic controlling type and eliminates empty energy consumption and the raising low-speed performance device of damaging of hydrodynamic retarder, belongs to vehicle auxiliary braking technical field.
Background technology
When vehicle is braked or frequently brakes in long-time lasting braking, high strength, brake disc temperature can significantly raise, and friction factor decline, degree of wear are increased the weight of, and occurs the even dangerous heat fade phenomenon of total loss of brake efficiency part.Although the application of anti-blocking brake system (ABS), EBD (Electric Brakeforce Distribution) (EBD) etc. has improved stability and the reliability of car brakeing, they are very micro-to the heat fade phenomenon effect of drg.At present, complemental brake system must be installed by the many countries that comprise China clearly passenger vehicle more than regulation certain specification, bogie, and effectively the load of Split flow brake device, improves car brakeing safety performance.Retarder is one of auxiliary brake of vehicle, mainly contains two kinds of hydrodynamic retarder and current vortex retarders.Abroad, hydrodynamic retarder, due to advantages such as lock torque is large, energy consumption is low, good reliabilitys, has replaced current vortex retarder substantially; At home, due to technology and cost, current vortex retarder is still leading product, but greatly develop hydrodynamic retarder, has become inexorable trend.
Hydrodynamic retarder, also referred to as hydrodynamic retarder, its inside is provided with driving wheel and fixed wheel, and driving wheel is connected with hydrodynamic retarder input shaft, and change-speed box outputting power is to hydrodynamic retarder, drive the rotation of hydrodynamic retarder input shaft, during work, in epitrochoidal chamber, be filled with as requested a certain amount of fluid, driving wheel drives fluid to rotate impact fixed wheel, a part of vehicle braking energy is changed into the heat energy of fluid, by cooling heat radiation system, dissipate, realize the object that car brakeing is slow, improve heat resistanceheat resistant decline performance.When the normal vehicle operation of hydrodynamic retarder is housed, while not needing hydrodynamic retarder work, the fluid in epitrochoidal chamber is got back to petrol storage tank, and now epitrochoidal chamber contains air.Because traditional hydrodynamic retarder axis of a movable block is meshed with transmission output shaft and is connected by gear, in Vehicle Driving Cycle process, driving wheel is driven all the time in slew mode by transmission output shaft, air in epitrochoidal chamber forms air circulation under driving wheel effect, produce certain lock torque, thereby cause vehicle energy loss.This degradation of energy is called the empty energy consumption of damaging, and also referred to as pump loss, accounts for greatly 4% of vehicle transmitted power, has reduced the fuel economy of vehicle.Improve empty method of damaging energy consumption and mainly contain two kinds, a kind of is by installing the devices such as valve block additional or inject air in epitrochoidal chamber in epitrochoidal chamber, the air circulation in destruction work chamber, thus reduce the empty energy consumption of damaging; Before the axis of a movable block, add a clutch equipment, when hydrodynamic retarder is not worked, disengaging of clutch, driving wheel stops operating, and reaches and eliminates empty object of damaging energy consumption.(the M that square is directly proportional of the lock torque of hydrodynamic retarder and driving wheel rotating speed
