Description
Technical field
The invention belongs to vehicle (automobile) transmission technology fields, and in particular to three clutch automatic speed changing of hybrid electric vehicle
Device lubricating system.
Background technique
Automatic transmission lubricating system is largely that electronic pump is added to provide lubrication flow using mechanical pump or mechanical pump at present,
Three clutch lubrication flows can carry out assignment of traffic using two or more regulating valves simultaneously.Lubricating system is using mechanical
When oil pump feed, since mechanical pump is driven by input shaft, after usual engine reaches certain revolving speed, mechanical pump discharge have it is more than needed,
Lubrication flow also has more than needed, then carries out oil return, has usually resulted in flow waste in this way, also energy consumption has been brought to waste.
Usually when three clutch lubrication flows distribute, flow point generally is carried out using two or more regulating valves
Match, the flow of lubricant passage way control each in this way is very accurate.Due to shafting lubrication, pressure-oil tank supply and first clutch C0 profit
It is sliding to need continuous lubrication, and lubrication flow demand do not need it is so accurate, therefore do not need with special regulating valve come into
The accurate lubrication flow of row is adjusted, and carries out assignment of traffic using two or more regulating valves, has both occupied hydraulic valve plate arrangement
Position, and cost is brought to waste.
Summary of the invention
The technical problem to be solved in the invention is: by setting electronic pump and throttle orifice, needing according to cooling and lubricating flow
It asks, adjusts electronics pump revolution and control lubrication flow, and the lubrication flow distribution being optimal with least valve, reduced with this cold
But flow bring energy consumption waste more than needed is lubricated, improves fuel economy, while only with a lubrication regulating valve and a plurality of oil circuit
The mode of supernumerary segment discharge orifice, reasonable distribution lubrication flow, while meeting many places lubrication needs, not only reduce the quantity of regulating valve, but also drop
Low cost.
Technical scheme is as follows:
A kind of automatic transmission lubricating system, including speed changer fuel tank, pump, lubrication regulating valve and a plurality of oil circuit.
The pump uses electronic pump, and electronics revolution speed is adjusted according to lubrication flow demand；
The electronic pump connects lubricating system working connection from speed changer fuel tank oil suction, the oil outlet of electronic pump；
Lubricating system working connection connection lubrication adjusts working connection, lubrication adjust working connection respectively with axis tooth lubricant passage way, the
One clutch C0/ rotor CR lubricant passage way and lubrication regulating valve are connected；
The lubrication regulating valve oil outlet is separately connected first clutch C0/ rotor CR lubricant passage way and second clutch
C1/ third clutch C2 lubricant passage way；

Oil circuit is connected；
C0/CR lubrication throttle orifice is connected in the first clutch C0/ rotor CR lubricant passage way, in axis tooth lubricant passage way
It is connected with axis tooth lubrication throttle orifice, the proportional relationship of the two throttle hole areas adjusts working connection to lubrication and carries out assignment of traffic.
Above scheme, using electronic pump provide lubrication flow, due to electronics revolution speed can according to lubrication flow demand into
Row is adjusted, and oil pump capacity can also be designed according to lubrication flow demand and revolving speed, accomplishes minimum injection rate as far as possible, to reduce
Flow more than needed achievees the purpose that reduce energy consumption.
Also, this programme is only with a lubrication regulating valve and a plurality of oil circuit supernumerary segment discharge orifice to the lubrication flow side of being allocated
Formula, so that it may reasonable distribution lubrication flow, while meeting many places lubrication needs, due to shafting lubrication, pressure-oil tank supply and the
One clutch C0 lubrication needs to continue flow, and flow demand does not need so accurately, therefore each oil circuit flow is using section
Discharge orifice is allocated flow, can not only save valve plate arrangement space, but also can reduce regulating valve quantity, thus reach saving at
This purpose.
Further, lubrication adjust working connection on be also respectively connected with lubricating system pressure limiting oil circuit and lubricating system pressure limiting valve into
Oil circuit connects lubricating system pressure limiting valve, lubrication between lubricating system pressure limiting oil circuit and lubricating system pressure limiting valve oil inlet oil circuit

When, lubricating system pressure limiting valve is opened, and lubricating system pressure limiting valve oil inlet oil circuit and oil return circuit are connected directly, and lubricating system is returned
Oil limits lubrication and adjusts pressure, keeps lubricating system more stable.
Further, it is also respectively connected with cooler and cooler by-passing valve on the lubricating system working connection, cooler passes through
Cooling oil return circuit adjusts working connection with lubrication and is connected, and the outlet of cooler by-passing valve adjusts working connection with lubrication and is connected, cold
But low-pressure filter is connected on oil return circuit.When lubricating system working connection and cooling two oil circuit pressure differences of oil return circuit reach
Pressure value is limited, cooler by-passing valve is opened, and lubricating system working connection and cooling oil return circuit are connected directly, and lubrication is adjusted in this way
Working connection is after cooler and low-pressure filter, it is possible to reduce cooler and low-pressure filter pressure loss bring pressure are not
Foot, while guaranteeing that pressure when lubricating regulating valve accurate flow adjustment is stablized.
Further, the cooling oil return circuit is also connected with pressure-oil tank repairing oil circuit, pressure-oil tank repairing oil circuit connection
Pressure-oil tank 23, pressure-oil tank repairing oil circuit are equipped with throttle orifice, lubricate throttle orifice with C0/CR and axis tooth lubricates throttle orifice
The proportional relationship of area, so that pressure-oil tank and the distribution of the lubrication flow of low-pressure reservoir are more reasonable.
Further, on the third clutch C2 lubricant passage way, first clutch C0 lubricant passage way and rotor CR profit
Lubricating oil road is respectively equipped with throttle orifice.
Compared with the prior art, the advantages of the present invention are as follows: lubrication flow is provided using electronic pump, electronics revolution speed can be with
It is adjusted according to lubrication flow demand, oil pump capacity can also be designed according to lubrication flow demand and revolving speed, be done as far as possible
To minimum injection rate, to reduce flow more than needed, achieve the purpose that reduce energy consumption；Due to shafting lubrication, pressure-oil tank supply and K0
Lubrication needs to continue flow, and flow demand does not need so accurately, therefore each oil circuit flow uses throttle orifice to flow
It is allocated, can not only save valve plate arrangement space, but also regulating valve quantity can be reduced, to achieve the purpose that save cost；
Lubricating system pressure limiting valve oil inlet oil circuit adjusts working connection with lubrication and connect, and lubrication adjusts working connection and filters in cooler and low pressure
After device, it is possible to reduce cooler and low-pressure filter pressure loss bring insufficient pressure, while guaranteeing to lubricate regulating valve essence
Pressure when really adjusting flow is stablized.By optimizing above, oil pump flow more than needed can both be greatly decreased, reduced hydraulic system energy
Consumption, and valve plate arrangement space can be saved, cost is reduced, while making up cooler and low-pressure filter pressure loss bring pressure
Hypodynamic defect.
