More than be the basic structure of the utility model; The steering pump body partly is wrapped in the support, has guaranteed that processing technology is easy to realize, can make full use of the space; Compact conformation; Help the miniaturization and the structural compactness design of driving engine, stressed uniform strength is high, satisfies the strength demand of driving engine in different operating modes.
As the optimization of the utility model, the said left side is the shaped as frame of del, and the pump housing coupling components on it is located at two jiaos of places, top of del respectively for guide is installed;
The said right side is a U type frame shape, and its upper pump casing coupling components is the installation base that has bolt mounting holes, be located at respectively U type frame two on summit and bottom centre place;
Such frame mode can alleviate the weight of support under the prerequisite of the intensity that guarantees support, practice thrift the material of using of support, reduces its manufacturing cost; The guide mounting means has solved because of Mismachining tolerance and has caused the following problems that occurs; Promptly can avoid because headspace is excessive causes installing not in place or headspace is too little that two kinds of hidden danger can't be installed etc.; Also can reduce the shearing stress of bolt, prolong bolt service life; The frame mode of coupling components and the position is set; Solved because the unsettled difficult problem of the not enough installation that causes of processing plane degree, reduced the processing and manufacturing difficulty simultaneously, can guarantee to connect firm, be easy to dismounting; And the intensity of each part is even after guaranteeing to connect, stress balance; Bolt and the V-shaped distribution of being connected of cylinder body make to install and fix reliably, have improved the reliability and the safety of product work.
As the another kind optimization of the utility model, said fwd inwall also is provided with along the groove of forward direction depression, and the lower surface of the said groove and the steering pump pump housing is suitable.
The design of groove can guarantee that the connecting relation between the pump housing and support is more strong, safe, reliable, belongs to multiaspect and fixes, and is difficult for slippage.
The utility model also has a kind of optimization, and the connection place of the connection place of said right side inwall up and down portion, inwall up and down, left side portion all has reinforced rib.
The place is provided with reinforced rib in the vertical velocity face, and this measure has significantly improved the strength and stiffness of support, helps stability of strutting system.
As the further optimization of the utility model, said support is the integral casting forming structure.
The processing technology of integral casting forming is simple, has guaranteed the support function and the requirement of strength of support, and compact conformation satisfies layout requirement between engine air, makes driving engine moulded attractive in appearance;
Owing to adopted above-mentioned technical scheme; The utility model compared with prior art; The technological advance of being obtained is: the whole mode of this support is good, intensity is high, and the steering pump body partly is wrapped in support, has guaranteed that processing technology is easy to realize; Reduce the shearing force of bolt simultaneously, improved the bolt working strength; Can make full use of the space, compact conformation, stressed uniform strength is high, satisfies the strength demand of driving engine in different operating modes; Directly be connected through the bracket bolt hole, need not other auxiliary device with engine cylinder-body, firm reliable, avoided the hidden danger of support because of the vibrations fracture.The utility model is applicable on the various automotivies engine, is used for the steering pump pump housing, cylinder body are linked.
