Description
Technical field
The invention belongs to technical field of automobile engine, specifically, the particularly gas nozzle mounting bracket on the motor car engine.
Background technique
At present, on vehicle fuel motor or fuel oil-combustion gas duel fuel engine, be provided with the gas nozzle of common rail, this gas nozzle is installed on the camshaft cover (having another name called valve mechanism cover) through support, is used for to the gas-duct jetting combustion gas.
Existing gas nozzle mounting bracket such as Fig. 4, shown in Figure 5; Be made up of with the crossbeam that is connected two limit framves 23 the symmetrically arranged limit of the right and left frame 2, said limit frame 2 is made up of last riser 2a, middle transverse slat 2b, following riser 2c and backboard 2d, and last riser 2a is positioned at the top of riser 2c down; Both parallel; Link to each other through middle transverse slat 2b between last riser 2a and the following riser 2c, and go up riser 2a and middle transverse slat 2b perpendicular, be welded with crossbeam 3 in the right and left between the bottom of transverse slat 2b.Said backboard 2d and following riser 2c are perpendicular, and the side of backboard 2d links to each other with the back of following riser 2c, and the top margin of backboard 2d links to each other with the back of middle transverse slat 2b.Have support mounting hole 4 in the bottom of backboard 2d, support is fixed in valve mechanism cover through the support mounting hole 4 that bolt passes the right and left.On last riser 2a, have nozzle mounting hole 5 and locating notch 6, locating notch 6 is semicircle.The deficiency of above gas nozzle mounting bracket is:
1) area of contact of support and valve mechanism cover is little; And the mounting point of the mounting point distance bracket of support top nozzle self is far away, and is not only relatively poor to the steadiness of nozzle support, and influenced by engine luggine; The backboard of support bottom is prone to rupture with following riser, and working life is shorter.
2) line of centres of nozzle mounting hole and locating notch is on same horizontal line, and the opening of locating notch is towards substantially horizontal, and is relatively poor to the locating effect of nozzle, causes nozzle loosening or come off easily.
3) complicated integral structure, the processing and fabricating operation is many, and cost of production is higher.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of can effectively preventing to rupture and nozzle support is located good motor car engine gas nozzle mounting bracket.
Technological scheme of the present invention is following: a kind of motor car engine nozzle holder; Has support body (1); Said support body (1) is made up of the base plate (1b) of symmetrically arranged side plate of the right and left (1a) and bottom; Side plate (1a) and vertical linking to each other of base plate (1b) have two symmetrical support mounting holes (4) on said base plate (1b), each support mounting hole (4) is near the side plate (1a) of respective side; Have locating notch (6) at the top of said side plate (1a), the opening of this locating notch (6) is towards last the place ahead; On said side plate (1a), also offer nozzle mounting hole (5), nozzle mounting hole (5) is positioned at the following rear of said locating notch (6).
Adopt above technological scheme, the bottom surface of support body base plate reclines with valve mechanism cover mutually, passes pilot hole corresponding on support mounting hole and the valve mechanism cover on the base plate by bolt, and the present invention is fixed on the valve mechanism cover.Compare with background technique, the area of contact of the present invention and valve mechanism cover is big, and greatly reduces height dimension; Like this present invention on valve mechanism cover, install firmly, reliable; Can firmly support nozzle,, also can not rupture even influenced by engine luggine.The locating notch at side plate top, both sides is used for nozzle is positioned; The opening of locating notch is towards last the place ahead; Put into that to take out nozzle all very convenient,, and can play the effect of support not only to the good positioning effect of nozzle; Make nozzle pass through nozzle mounting hole and bolt and be connected more firmly with support, prevented that effectively nozzle is loosening or come off.Simultaneously, moulding of the present invention is simple, and processing and fabricating is easy, and cost of production is lower, is particularly conducive to batch process.
Said support body (1) is through the plate stamping moulding, and said side plate (1a) extends to the back upper place earlier, and upwards the place ahead is circuitous again.Above structure be easy to processing, and as much as possible economical with materials, dwindle the volume of entire bracket, help reducing production costs.
Arching upward in the middle part of said base plate (1b) upwards distortion, has improved the intensity and the natural frequency of base plate greatly, can prevent bottom deformation, reduces the vibration and the noise of base plate itself.
Said support mounting hole (4) is oval, can regulate the mounting point of nozzle holder so as required, helps quick assembling.
Said locating notch (6) is " U " shape, not only is easy to processing, and remarkable to location, the supporting effect of nozzle.
For when reducing the nozzle holder height dimension, can effectively support the location to nozzle, have 55-65 ° angle Q between the horizontal plane at the same base plate of the line of centres (1b) place of said locating notch (6) and nozzle mounting hole (5).
Beneficial effect: the present invention installs on valve mechanism cover firmly, reliable, can not rupture, and can firmly support nozzle, prevented that effectively nozzle is loosening or comes off, and has characteristics such as moulding is simple, processing and fabricating is easy, cost of production is low.
