Abstract
The invention relates to a device for measuring the motion range of an automobile power assembly relatively to an automobile body engine chamber. The device for measuring envelope of the automobile power assembly comprises ranging sensors which are mounted in the automobile engine chamber, and are used for measuring displacement data of the automobile power assembly. By measuring the displacement data of the automobile power assembly under different motion states of the automobile, enveloping surfaces of the automobile power assembly are acquired, so as to determine dynamic clearances between the automobile power assembly and surrounded components; reasonable references are provided for automobile manufacturers to layout design of engine chambers.
Description
Technical field
The present invention relates to a kind of automobile power assembly envelope measurement mechanism, be specifically related to the measurement mechanism of the range of movement of the relative vehicle body nacelle of a kind of automobile power assembly.
Background technology
The producer of domestic independent research automobile is in designing and developing, and automobile front chamber layout is a complicated thing always.Because the parts of front deck are more, parts need reserved certain static clearance and dynamic clearance each other, and account for engine and the gap requirement maximum of wheel box to periphery part of volume maximum.Sometimes often in order to increase the gap of several millimeters, design engineer needs the relative position between adjustment component repeatedly, even revises the profile of parts, to reach the target call that meets movement clearance.So often waste a large amount of working times and cost of development.Because the moving displacement of automobile power assembly different parts is different, so the requirement of the peripheral clearance to automobile power assembly also should be different because of the difference of position, the space that saving is certain is arranged in the space that can be so just front deck, also can save certain construction cycle and R & D Cost.
At home in the producer of independent research automobile, also lack at present corresponding data accumulation, design data is to be based upon on the empirical value of external motor corporation mostly, and the analysis operating mode using is also Europe standard of beauty, makes the gap of automobile power assembly periphery require unreasonable.The in the situation that of very limited in front deck space itself, waste again a large amount of spaces.
Owing to lacking corresponding measurement mechanism, domestic Ge great automobile production producer lacks corresponding data accumulation, therefore can not propose specific requirement at the dynamic clearance of different motion state to automobile power assembly, causes automobile engine nacelle topological design process loaded down with trivial details.
Summary of the invention
Of the present invention is for a kind of automobile power assembly envelope measurement mechanism is provided, can measure motor racing time, and the range of movement of the relative vehicle body nacelle of automobile power assembly.
To achieve these goals, the technical solution used in the present invention is: a kind of automobile power assembly envelope measurement mechanism, is characterized in that: comprised and be arranged on the distance measuring sensor for measured automobiles power assembly displacement data in automobile engine nacelle.
Adopt automobile power assembly envelope measurement mechanism of the present invention, can be by the displacement data of measured automobiles automobile power assembly under different motion state, obtain the enveloping surface of automobile power assembly, thereby definite automobile power assembly and the around dynamic clearance between each parts, for automobile production producer provides rational basis to the topological design of nacelle.
Brief description of the drawings
Fig. 1 is the installation site schematic diagram of distance measuring sensor on automobile power assembly;
Embodiment
Below in conjunction with accompanying drawing, one embodiment of the present of invention are elaborated, for convenience of explanation, in this figure, automobile power assembly is reduced to rectangular structure.
A kind of automobile power assembly envelope measurement mechanism, comprises and is arranged on the distance measuring sensor 20 for measured automobiles power assembly 10 displacement datas in automobile engine nacelle.Distance measuring sensor 20 can record the displacement data of automobile power assembly 10 under different motion state, thereby can obtain the gap variation relation between automobile power assembly 10 and other parts, for the design of position, shape and the size of automobile power assembly in nacelle 10 and other parts provides foundation.
Below illustrate measurement scheme of the present invention.
Distance measuring sensor 20 is arranged on automobile power assembly 10 along on the end face of vehicle commander, overall width, three mutually perpendicular directions of overall height, distance measuring sensor 20 is so set, can adopts less components and parts and obtain required automobile power assembly 10 along the displacement data in vehicle commander, overall width and overall height direction.
Automobile power assembly 10 arranges two distance measuring sensors 20 along the end face of vehicle commander's direction, and the detection direction of two distance measuring sensors 20 points to vehicle front.Be convenient to like this installation and removal of distance measuring sensor 20, be also convenient to the selection of distance measuring signal reflecting surface.
Automobile power assembly 10 is along a high position that is positioned at this end face in two distance measuring sensors 20 of the end face setting of vehicle commander's direction, another is positioned at low level, so not only can record the displacement data of automobile power assembly 10 along vehicle commander's direction, can also obtain the rotational angle of this end face by two distance measuring sensor 20 data measureds are carried out to calculation process, and then can converse the displacement data of this arbitrary position of end face.
Automobile power assembly 10 arranges respectively two distance measuring sensors 20 along the end face of overall width and overall height direction, two distance measuring sensors 20 on each are all arranged to one and are positioned at a high position, another is positioned at low level, can obtain the displacement data of overall width and the overall height direction of automobile power assembly 10, and obtain the displacement data of arbitrary position on the rotational angle of overall width and two end faces of overall height direction and two end faces by data being carried out to calculation process.
In body of a motor car nacelle, face distance measuring sensor 20 places flat board is installed, avoid occurring the data error that not exclusively occurs because of reflecting surface out-of-flatness or to signal reflex, be conducive to stability and the accuracy of the data that raising finds range.
Described distance measuring sensor 20 is the infrared distance sensor with data storage device.Distance measuring sensor 20 transfers data to data processing main frame after measuring and collect data, by data processing software, data are processed, can calculate under different motion state the displacement data of optional position and the deflection angle of each end face on automobile power assembly 10 end faces, thus to the design of automobile power assembly 10 especially its around design and the layout of parts provide reference frame.
