Abstract
The utility model discloses a double pump system for double clutch derailleur, including oil tank (1) and mechanical oil pump (2), mechanical oil pump (2) the oil inlet with oil tank (1) link to each other, oil -out and the working connection of mechanical oil pump (2) link to each other, it still include with mechanical oil pump (2) parallel connection electronics oil pump (3) that set up, electron oil pump (3) the oil inlet with oil tank (1) link to each other, oil -out and the working connection of electron oil pump (3) link to each other. This double pump system is under preset flow demand's prerequisite, and it is little to reduce the loss of machinery oil pump delivery, energy consumption, the economical height of fuel.
Description
Technical field
The utility model relates to dual-clutch transmission field, particularly a kind of double pump system for dual-clutch transmission.
Background technique
In today that automobile is day by day popular, automotive engineering development, the requirement of client to automobile is more and more stricter.Double-clutch automatic gearbox is accepted by market and client gradually through development for many years.But problem is, existing dual-clutch transmission is generally be that hydraulic system is for oily flow by a mechanical oil pump.Because oil pump feed amount and rotating speed are relevant, in order to meet the requirement of hydraulic fluid flow rate under slow-speed of revolution when car is started to walk, the size of oil pump is wanted larger and can be met.And in high-revolving situation, the flow of oil pump is above demand, and unnecessary oil comes back to fuel tank or pump filler opening, and energy loss is large.
Summary of the invention
Technical problem to be solved in the utility model is: provide a kind of under the prerequisite of given flow demand, can reduce machinery oil pump delivery, energy loss is little, the double pump system for dual-clutch transmission that fuel-economy type is high.
The technical scheme in the invention for solving the above technical problem is: a kind of double pump system for dual-clutch transmission, comprise fuel tank and mechanical oil pump, the filler opening of described mechanical oil pump is connected with described fuel tank, the oil outlet of described mechanical oil pump is connected with working connection, it also comprises with described mechanical oil pump and is connected with the electronic oil pump put, the filler opening of described electronic oil pump is connected with described fuel tank, and the oil outlet of described electronic oil pump is connected with working connection.
Compared with prior art, the utility model has the advantage of: this double pump system being used for dual-clutch transmission adopts electronic oil pump and mechanical oil pump to get involved simultaneously and uses oily flow for hydraulic system provides.Double pump is fuel feeding as required, and time slow-revving, electronic oil pump Aided Machine oil pump is to working connection fuel feeding, and when high rotating speed, mechanical oil pump can meet the demand of working connection, and electronic oil pump just can assist other oil mass demands, or closes.Like this, mechanical oil pump designs according to traffic demand during high speed, under the prerequisite of given flow demand, can effective minification, and can reduce machinery oil pump delivery, energy loss is little, and fuel-economy type is high.
As preferably, it also comprises the selector valve outputting to working connection or cooling oil path for switching electronic oil pump, and the entrance of described selector valve is connected with the oil outlet of described electronic oil pump, and the outlet of described selector valve is connected with described working connection or cooling oil path.Like this, can be switched the oil feeding line of electronic oil pump and be carried out stable working connection pressure or improve lubricating oil path flow by arranging of this selector valve, it is better that the effect of electronic oil pump plays.
As preferably, it also comprises the switch electromagnetic valve for controlling described selector valve, and described switch electromagnetic valve is electrically connected with gearbox control system, and described switch electromagnetic valve is connected with described selector valve.Like this, by the switching of mobility in gearbox control, electronic oil pump fuel feeding optionally outputs to working connection or cooling oil path.During low engine speed, electronic oil pump is to working connection fuel feeding, and during high rotating speed, switch electromagnetic valve gives cooling as signal switching, lubricating oil path fuel feeding.Control more convenient, oil circuit configuration is more reasonable.
As preferably, the oil outlet of described mechanical oil pump is connected with the first one-way valve.
As preferably, the oil outlet of described electronic oil pump is connected with the second one-way valve.
