Technical field
, being capable of pump by means of the piston pump the present invention relates to a kind of use of pump installation and piston pump for motor vehicle Inhale fluid, especially liquid, such as water or oil, for example with this fluid supply unit and/or produce it is enough, for promoting hydraulic pressure The operating pressure of dynamic device operation.
Background technology
It is known to use pump in a motor vehicle in order to produce enough Fluid pressures.In order that motor-driven for making for operating The hydraulic actuator operation for the starting clutch that the drive shaft of car engine is coupled with vehicle transmission, for example, can use electricity The pump of operation, the pump by hydraulic oil from reserve tank pump into accumulator, so as to produced in accumulator it is enough, for operating The operating pressure of actuator.Therefore, the fixing component of pump and motor vehicle is fixed and with being capable of electrically driven (operated) pumping plant.At this In, it can be extracted from automotive battery for making the electric energy of pump operation.
In the presence of the constant demand of the power consumption in reduction motor vehicle.
The content of the invention
The task of the present invention is that there is provided the measure that can realize power consumption small in motor vehicle.
According to the present invention, a kind of pump installation for motor vehicle is set, the pump installation has the driving of motor car engine Axle, the drive shaft is used to provide the torque in the case of rated speed n with rotation inhomogeneities, the motor vehicle and carries The piston pump coupled with the drive shaft, wherein, there is the piston pump pump case accelerated by the drive shaft and one to set Put between the first chamber and the second chamber, the pump piston that can be moved relative to the pump case, the pump piston is used for fluid By first Room and/or the second Room pump to an accumulator from reserve tank, wherein, the motion of the pump piston and institute The motion for stating pump case is so decoupled so that the pump case can be due to rotation inhomogeneities relative to pump piston fortune It is dynamic.
Coupled by the piston pump with drive shaft, especially with the bent axle of piston IC engine, piston pump can with drive shaft Rotating speed it is proportional angular speed rotation.Simultaneously as the engine combustion of motor car engine and/or due to starting motor-driven vehicle Rotation inhomogeneities is also delivered on piston pump caused by the physical dimension of the mechanical connecting device of machine on the driving shaft.This leads Cause, for current rated speed n, piston pump is further accelerated by one in circumferential direction due to the rotation inhomogeneities And braking, wherein, this acceleration and braking are substantially periodically repeated according to structure type.By the motion and the pump that make pump piston The motion of housing is decoupled, the rotation inhomogeneities of angular speed of the pump piston due to being applied on piston pump and carry out relative to pump case The relative motion of body, is achieved in pump-absorb action, and the pump-absorb action can be substantially only through the driving with twisting vibration The aerodynamic power of axle and realized without using additional electrical energy, be achieved in power consumption small in motor vehicle.
Pump piston especially can be substantially directed to free movement in pump case.Pump piston can implement can be relative For angular speed on piston pump, proportional to rated speed is applied in circumferential direction and/or in tangential direction Relative to pump case motion.Herein, pump piston can the quilt on the radially and/or axially direction of pump case whole or in part It is oriented to.Especially such configuration pump piston and pump case it is decoupled so that pump case is mechanically coupled with drive shaft (especially without relative The connection of motion ground) and pump piston is mechanically separated with drive shaft, or on the contrary so that pump case mechanically separated with drive shaft and Pump piston is mechanically coupled with drive shaft and (is especially connected without relative motion).For example it is achieved in that decoupled so that pump piston energy It is enough that substantially with rated speed rotation, pump case can be rotated with rated speed and the rotation being superimposed inhomogeneities, or instead It so that pump piston can pump case can be substantially with specified with rated speed and the rotation of the rotation being superimposed inhomogeneities Rotating speed rotates.Herein, piston pump can either in running under power, also can inertia operation in and/or in idle Pump-absorb action is provided by the drive shaft of rotation.Pump piston is preferably so decoupled so that be applied to the inertia force energy in pump case It is enough only indirectly, particularly by being arranged on the first Room and/or fluid in the second chamber is delivered on pump piston.Pump piston is especially Without the piston rod that can be connected with external driver device.Thus, pump piston can be configured to no drive device, thus, it is possible to The correspondingly simple structure of piston pump is enough realized, because the attachment means of extra power can be saved.Preferably, pump piston can Substantially merely due to the inertia force of pump piston and if necessary with pump piston connect inertia mass together with from initial position transport Dynamic to come out, pump piston can vibrate around the initial position relative to pump case.
Preferably, accumulator sets limited valve, so that no more than the maximum pressure defined in accumulator.Pressure limiting valve Fluid by piston pump pumping can especially be directed back in reserve tank.
It is particularly preferred that the mass cg of pump case is turned up the soil arrangement, piston pump relative to a rotation axis with radius R interval It can be rotated around the rotation axis, wherein, piston pump enables in particular to rotate with radius R around the rotation axis of drive shaft.It is living Plug pump can for example be connected with the preliminary quality (especially in driving side) being connected with drive shaft of double mass flywheel.Pass through selection half Footpath R, can influence the stroke of the maximum possible of pump piston in the case where the rotation inhomogeneities of rated speed is given. By selecting the inertia mass of pump piston, can inertia force of the influence on pump piston, thus can also influence maximum can The pump pressure of energy.By select the sensing of pump piston treat pumping fluid end face area, can also influence maximum possible Pump pressure.
In particular, pump piston is connected with the pendulum mass that can be moved relative to pump piston.It can be improved by the pendulum mass Gross mass, so that pump piston can be with accordingly higher pressure pumping.Thus, pump piston in itself can be Comparatively speaking light and small Ground determines size.It is particularly likely to, pump-absorb action is improved relative to the relative motion of pump piston by pendulum mass.For example may be used So to coordinate motion of the pendulum mass relative to pump piston so that in the expected frequence of the rotation inhomogeneities of the swing of pendulum mass In the case of, the pump piston braked in pumping is additionally accelerated to pumping direction.In particular, by pendulum mass from pump case Draw, so that the size of pendulum mass determines not limited by the physical dimension of pump case.Preferably, pump piston passes through in the axial direction On the guide device that is set towards pump piston, such as tenon/groove attachment means be oriented to, without relative to pump piston Radially outer and/or inner radial are oriented to pump piston by pump case.This enables connection of the pendulum mass on pump piston Carried out in radial directions through pump case without damaging pump piston being sufficiently guided in pump case.Further it is possible that logical With crossing the so big degree of the pendulum mass rotation inhomogeneities in terms of pump piston of decaying so that substantially only pump case is rotated not The relative motion moved and thus carry out frequency relative to pump piston, with rotation inhomogeneities of uniformity.
Preferably, pump piston with can relative to pump piston move, it is with pendulum mass, for making inertia according to rotating speed The centrifugal force pendulum connection that torque changes.The pendulum that pendulum mass can be influenceed according to current rated speed by the centrifugal force pendulum is made With.It is thereby possible to, changing according to current nominal rotating speed for rotation inhomogeneities is considered in the pump-absorb action of piston pump Frequency.Thus, the rotating speed that the pump-absorb action of piston pump can be substantially with drive shaft is unrelated.
It is particularly preferred that pendulum mass be provided for wobble frequency rate vibration with terms of pump piston of decaying relative to rated speed N rotation inhomogeneities, wherein, the wobble frequency rate substantially correspond to it is minimum, substantially not by the engine order of vibration damping (Motorordnung), especially second or trimotor order.Herein, such understanding is utilized, i.e. according to real Depending on existing vibration damping and/or the cylinder number of motor car engine, treat that expected, the rotation inhomogeneities with crest amplitude has phase Should be in the frequency of the second engine order (1/2n) or trimotor order (1/3n).
In particular, piston pump is not coupled substantially vibration damping with drive shaft.Preferably, motor car engine and piston pump it Between power flow displacement section substantially without with the torsional vibration damper of damping element that can be movable relatively.Thus, may be used Can, from motor car engine imported into drive shaft in rotation inhomogeneities can imported into piston with not filtering substantially In pump, especially in pump case.Thereby, it is possible to substantially avoid entering in advance in the power flow due to rotation inhomogeneities Capable decay and the pump-absorb action for causing reduction piston pump.

It is particularly preferred that the volume of the volume of the first pump chamber and the second pump chamber is used for the pump in the substantially representative of pump piston It is substantially formed objects in initial position vibration midpoint, being limited of piston.Pump piston can be especially in circumferential side Substantially it is centrally positioned in upwards in pump case.Realized thereby, it is possible to both for the first pump chamber also for the second pump chamber identical Pump-absorb action.Thus, enable in particular to both in the case of acceleration or under braking by rotate inhomogeneities realize it is identical Pumping.
In particular, for pumping fluid, not only the first Room but also second Room all with reserve tank and accumulator, especially with it is same Accumulator is connected.Because can be both by the first Room also by second Room pumping fluid, piston pump can be both in pump piston along pump Second axle in opposite direction with first axial direction during the first axial direction relative motion of housing also in pump piston along pump case To providing pump-absorb action during the relative motion of direction.It can either can also pass through in the case of by rotating inhomogeneities acceleration Pumping is realized in the case of rotation inhomogeneities braking.Especially both by the fluid of the first Room or by the fluid pump of second Room to same In accumulator, so as to form comparable operating pressure in two rooms.Especially extracted from same reserve tank for the first Room Fluid and the fluid for second Room.But it is also possible to set different reserve tanks.It is particularly preferred that extracted from accumulator Fluid can back into reserve tank, so as to realize fluid circuit.
Preferably, the first Room by be especially configured as check-valves, unidirectional first inlet valve be connected with reserve tank and By be especially configured as check-valves, unidirectional first dump valve is connected with accumulator and/or second Room is by being especially configured as The second check-valves, unidirectional inlet valve is connected with reserve tank and by second row that be especially configured as check-valves, unidirectional Go out valve to be connected with accumulator.By this line construction one hydraulic pressure rectifier of formation, the hydraulic pressure rectifier and pump piston relative to The direction of pump case relative motion independently only forces the pumping direction of piston pump from reserve tank to accumulator.Unidirectional pumping side To such as can also by lost motion device realize.
It is particularly preferred that accumulator is connected with a hydraulic actuator, the hydraulic actuator particularly for one clutch of operation, It is preferred that one is used to make the starting clutch that motor car engine is coupled with vehicle transmission.Thus, it is possible in starting motor-driven vehicle A pressure is produced when machine is run in accumulator by piston pump, so as to can be hydraulically and/or annoying with the pressure operation The automotive component run dynamicly.Enable in particular to be positioned to starting clutch to be spatially near piston pump, so as to form work Fill in corresponding short connecting pipe between pump and starting clutch.
The invention further relates to the use of piston pump, the piston pump in particular can be constructed and improved as described previously Pump installation a part, the piston pump is used to couple with the drive shaft of motor vehicle, wherein, the piston pump by drive shaft with being added Pump piston between the pump case of speed and setting between the first chamber and the second chamber, being moved relative to pump case, the pump piston For fluid to be passed through into the first Room and/or second Room pump to an accumulator from reserve tank, wherein, the motion of pump piston and the pump The motion of housing is so decoupled so that pump case can be due to rotation inhomogeneities relative to pump piston motion.Pass through Make pump piston motion and pump case motion it is decoupled, pump piston is uneven due to the rotation for the angular speed being applied on piston pump Property and carry out the relative motion relative to pump case, be achieved in pump-absorb action, the pump-absorb action can be substantially only through Aerodynamic power with the drive shaft of twisting vibration and realized without using additional electrical energy, it is small in motor vehicle thus, it is possible to realize Power consumption.
