Abstract
The utility model specifically provides a transition plug cover, which comprises a boss for sealing a steering pump mounting hole and a flange for fastening the transition plug cover to a diesel engine. The flange is provided with a plurality of through holes for being connected with the diesel engine. The plug cover has the advantages of simple structure, reliable sealing, good assembly process, capability of reducing resource and cost waste and convenience in generalization.
Description
Technical field
The utility model relates to a kind of use for diesel engine transition blanking cover, particularly a kind of servo-steering pump transition blanking cover.
Background technology
In the steering swivel system of present vehicle, all equip this core component of servo-steering pump basically.This servo-steering pump is driven by the train of gears of diesel engine, but is parts independently with respect to diesel engine, is not must piece installing, and, be not with this servo-steering pump when providing diesel engine to car load factory under a lot of situations, but assemble again in car load factory.In this case, diesel engine must seal the hole that is used for this steering pump of dress earlier before loading onto the servo-steering pump temporarily.
Generally speaking, can adopt a horminess metal plate as interim blanking cover, in case but after diesel engine loaded onto the servo-steering pump, this interim blanking cover had just cancelled; And, if the variable thickness of the thickness of this metal sheet and steering pump mounting flange causes, make the bolt that is contained in the fastening screw that is used for installation servo-steering pump on the diesel engine when dress servo-steering pump, also must change, if in order to change this binding bolt, must make this transition thickness of metal sheet and the consistency of thickness of steering pump mounting flange, certainly will cause this transition with the complex structure of metal sheet, increase metallic material and difficulty of processing.Moreover, the attachment face of servo-steering pump is metal and the contacting of metal on metal sheet and the diesel engine, in order to guarantee sealing, must increase packing seal between the two or be coated with sealant, packing seal or sealant are disposable product, simultaneously, on changing the outfit, must remove packing seal or the sealant that remains on the diesel engine earlier before the servo-steering pump, increase assembly process, reduce efficiency of assembling, also very easily cause when removing residue, diesel engine being used for installing the attachment face damage of servo-steering pump, need to change parts and components of diesel engine.So all, all cause the manufacturing cost of vehicle to increase, waste resource simultaneously, do not meet energy-conserving and environment-protective.
The utility model content
For overcoming above problem, the utility model provides a kind of cost cheap, and sealing is reliable, needn't change the transition blanking cover of binding bolt during assembling servo-steering pump.
The utility model is by the following technical solutions:
A kind of transition blanking cover comprises a boss, is provided with a flange in the boss bottom, and described flange is provided with two for the through hole that is connected with diesel engine.
The mounting hole size coupling of the servo-steering pump of the outer profile size of described boss and diesel engine, and both adopt interference fit.
Described transition blanking cover adopts elastomeric material.
The position of described two through holes is corresponding with the position of the mounting hole of servo-steering pump.
The installation consistency of thickness of the thickness of described flange and servo-steering pump.
The beneficial effects of the utility model are:
Simple in structure, sealing is reliable, and assembly process process is good, reduces the waste of resource and cost, is convenient to promote.

Fig. 2 is front view of the present utility model;
Fig. 3 is the A-A cutaway view of Fig. 2;
1 first through hole among the figure, 2 second through holes, 3 boss, 4 flanges, 5 pits.
The specific embodiment
Transition blanking cover of the present utility model adopts elastomeric material, as shown in Figure 1, the centre of transition blanking cover is provided with a boss 3, is provided with in the bottom of boss 3 for the flange 4 that this transition blanking cover is fastened on the diesel engine, and flange 4 is provided with first through hole 1 and second through hole 2 that is connected with diesel engine.
For the mounting hole size coupling of the servo-steering pump of packing into, adopt interference fit to be used for sealing on the outer profile size of described boss 3 and the diesel engine; The plane contact of servo-steering pump is installed on the plane of close boss 3 one sides and the diesel engine on the flange 4; The installation consistency of thickness of the thickness of flange 4 and servo-steering pump; Be used for this transition blanking cover is installed on the distribution of the through hole of diesel engine on the flange 4, distribute consistent with the mounting hole that the servo-steering pump is anchored on diesel engine.
For saving material, under the matching requirements that guarantee this transition blanking cover, the opposite side of boss 3 can adopt pit 5 structures.
During installation, be used for installing the mounting hole of servo-steering pump on the diesel engine of only boss 3 need being packed into, then the bolt of fastening servo-steering pump passed first through hole 1, second through hole 2, the transition blanking cover is contained on the diesel engine.Before changing the servo-steering pump, only need be pulled down this transition blanking cover and get final product, and need not to change other parts.
Claims (5)
