Description
Technical field
The invention belongs to heavy-duty vehicle technical field, particularly a kind of hydrodynamic retarder for the windage loss eliminated heavy-duty vehicle auxiliary braking system, with closing appliance and oil circuit control.
Background technology
Hydrodynamic retarder is a kind of vehicle auxiliary braking system device, is made up of stator and rotor two parts.Rotor drives fluid power to rotate and impact stator, and stator produces a reaction force acts on rotor by liquid, thereby hinders the rotation of rotor.Hydrodynamic retarder is converted into the mechanical energy of equipment the heat energy of liquid, and by cooling system, it is dispelled the heat.
Compared with other brake system: the braking torque of hydrodynamic retarder is directly proportional to five powers of the sum of squares circulate circle diameter of its rotating speed, thereby the hydrodynamic retarder of high rotating speed main cycle circular diameter has larger braking torque; The wearing and tearing of hydrodynamic retarder machinery-free, can be for a long time without the operation of overhauling, longer service life.
When hydrodynamic retarder is applied on highway, can greatly improve braking and transmission quality.In the time that long steep grade is descending, it can be accurate and the resistance of downstream rate is provided reliably continuously, ensures traffic safety; In the time that level road is braked, it can be reposefully without wearing and tearing provide approximately 90% required braking force of vehicle, finally make vehicle parking by friction braking.In whole braking procedure, velocity variations is even, does not occur impact phenomenon.In addition, due to the gradual braking of vehicle, reduce the damage of road pavement, thereby reduce pavement maintenance work capacity.Germany's traffic regulation regulation, city motor bus more than 5.5t and autotruck more than 9t must have the auxiliary braking beyond normal brake application, flexible, safe and reliable to ensure running car.This vehicle of rule request must, at long 6km, on the ramp of the gradient 7%, can travel with the speed of 30km/h safely and reliably.Facts have proved: the vehicle that hydrodynamic retarder is housed can be good at meeting above-mentioned requirements.
In the time that vehicle needs auxiliary braking, hydrodynamic retarder produces the needed lock torque of vehicle by rotor, fluid and stator; In the time of normal vehicle operation, makeup oil in hydrodynamic retarder, but rotor always in rotary state, when rotor rotates, intracavity gas circulates, and causes windage loss, it accounts for 6% left and right of continuous brake power.If so can eliminate the windage loss of hydrodynamic retarder, will greatly save unnecessary energy dissipation.
Prior art is retrieved, find to cut off and be input to retarder rotor power to eliminate in the information of hydrodynamic retarder windage loss by closing appliance, related to the present invention more representative be Chinese invention patent CN101239616A and Chinese utility model patent CN202531689U.CN101239616A discloses a kind of hydrodynamic retarder mechanism that can eliminate pump loss, it has increased a friction clutch device at input shaft front end, realize importing into and cutting off of propulsion source, but increase greatly the axial length of hydrodynamic retarder, increased certain difficulty to the layout of miscellaneous part; CN202531689U discloses a kind of hydrodynamic retarder, it increases a constant pressure synchronizer at power intake, increase a set of shift fork system, the axial length that has not only increased hydrodynamic retarder also makes steering unit more complicated, simultaneously through facts have proved: constant pressure synchronizer easily produces and beats tooth phenomenon in synchronizing process, works unreliable.
