Description
Technical field
The present invention relates to a kind of two internal gear pumps that have two internal gear pumps that have according to the feature as described in the preamble of claim 1.This pair internal gear pump is arranged for have the anti-slip regulation function hydraulic vehicle brake equipment of (ABS, ASR, ESP, FDR), and wherein, each in these two internal gear pumps is provided for a brake circuit.This pump in having the hydraulic vehicle brake equipment of anti-slip regulation function is also referred to as dump pump, and wherein, piston pump is common but gear type pump is uncommon.
Background technology
Known such pair of internal gear pump from open source literature DE 10 2,007 054 808 A1.It has and has common two internal gear pumps that are used for jointly by the pump shaft of electric motor drive.With axial distance abreast, be arranged on the pump shaft to prevent counterrotating mode, wherein, the gear that is arranged on this pump shaft is called as miniature gears to the miniature gears of these two internal gear pumps coaxially.The gear ring of these two internal gear pumps (gear that has internal tooth) arranges prejudicially with respect to miniature gears and pump shaft, and at peripheral position or in the neighboring area with pinion.Known two internal gear pumps have and have multi-piece type pump case two basin shapes, columniform case half, and these two case half axially are plugged together.Each case half is held in two internal gear pumps.Partition wall in pump case is arranged between these two internal gear pumps, and two internal gear pumps separately and are hydraulically separated with the thickness of this partition wall.This partition wall can be regarded as the part of pump case.The side of opening wide of the case half of this basin shape faces with each other, " bottom " of this case half form the end wall of pump case and at distolateral place to this pump case of outer closure." bottom " or end wall have interstitial hole, and pump shaft can be rotated to support in this interstitial hole.
Open source literature DE 100 53 991 A1 disclose another such pair of internal gear pump.This pair internal gear pump also has the multi-piece type pump case of the case half that has two basin shapes, holds two internal gear pumps in described case half.Distolateral the facing with each other of opening wide of the case half of basin shape is furnished with partition wall between it, case half abuts on the end face of this partition wall.In order to connect, case half surround have around flanging part
The periphery of partition wall.This pair internal gear pump is inserted into as the pump portion of pushing in the hydraulic block of hydraulic vehicle brake equipment with its pump case, and this hydraulic block makes as two internal gear pumps of Hydraulic Pump or dump pump and hydraulically links with other hydraulic component of the anti-slip regulation device of vehicle brake apparatus.This member for example is electromagnetic valve, boiler check valve, hydraulic accumulator and shock absorber.This hydraulic block is connected on the main brake cylinder and the wheel braking cylinder is connected on this hydraulic block.
Summary of the invention
Have the described feature of claim 1 according to of the present invention pair of internal gear pump in, partition wall is the component part of the one of pump case.This pump case is preferably opened wide at two distolateral places and is sealed by removable case lid or other member, thereby this internal gear pump can be installed to this housing from distolateral.Advantage of the present invention is, saved the sealing between partition wall and pump case, do not have sealing problem at this position, and when assembling partition wall can be in pump case warpage because partition wall be not assembling but the component part of the one of pump case.Also simplified the pump connection part, be the possible guide portion of pump input part and pump efferent by partition wall, there is not the interconnecting gangway that seals to the need the partition wall from the pump connection part of pump case, and got rid of because the mistake assembling of partition wall can't communicate the pump connection part in pump case with the pump connection part that is associated in partition wall.
Except so-called crescent pump, the internal gear pump in thought of the present invention also is interpreted as the ring gear pump, but this exemplifies and is not closure.
Dependent claims to as if of the present invention favourable design plan and the improvement project that in claim 1, provide.
Preferably, this pair internal gear pump is arranged in the hydraulic block of the hydraulic vehicle brake equipment with anti-slip regulation function, and this hydraulic block forms pump case (claim 2).This hydraulic block make two internal gear pumps hydraulically with other hydraulic package (for example electromagnetic valve, boiler check valve, hydraulic accumulator, hydraulic damper, pressure sensor) hydraulic communication of the anti-slip regulation device of vehicle brake apparatus.This hydraulic block is connected on the main brake cylinder, and the car side brake of vehicle brake apparatus is connected on the hydraulic block.Two internal gear pumps of two internal gear pumps hydraulically be separated from each other and two internal gear pumps in each be assigned to a brake circuit of vehicle brake apparatus.This internal gear pump is Hydraulic Pump and is also referred to as dump pump in the vehicle brake apparatus with anti-slip regulation function.
If the pump connection part, be that at least one pump input part and/or pump efferent are guided through partition wall (this is the described object of claim 4), before being installed to internal gear pump in the pump case, can be with possible pump valve from the corresponding distolateral corresponding pump connection part that is inserted in the partition wall of pump case.This pump valve for example can be boiler check valve, its when internal gear pump is static, prevent braking liquid possible pass through flow back to opposite with throughput direction of internal gear pump.This pump valve can be saved in the partition wall that is installed in pump case spatially.
