Abstract
Disclosed is an automobile rear axle bending detection instrument used for performing bending detection towards rear axles of large, medium and small size trucks. The principle of the rear axle bending detection instrument includes that a light emitting device of a transmitting device generates a light spot; the light spot is projected to graduation of a measuring surface of a receiver device based on linear theory of light; whether the rear axle is deformed or bent is judged according to the position of the light spot on the graduation. The automobile rear axle bending detection instrument is mainly composed of parts in abstract attached diagram, including a transmitting device (the transmitting device comprises an outer shell body 1, an inner shell body 2 and a light emitting device 3) and a receiver device 4. The inner shell body of the transmitting device can have circular motion in the outer shell body taking the central line of the outer shell body as circle center; the light emitting device generates light spot; the outer shell body, the central line of the inner shell body and the light spot are in the same central line. The concrete implementation mode includes that the outer shell body is fixed on a half-axle sleeve of automobile rear axle or a rear axle wheel hub; the light spot on the transmitting end and emitted by the light emitting device and the half-axle sleeve of the automobile rear axle are in the same central line; the light spot is projected to the graduation on the measuring surface of the receiver device on the other side.
Description
Affiliated technical field:
The back axle that the utility model relates to a kind of cargo vehicle to various large, medium and small types carries out the instrument of curved detection.
Background technology:
The back axle of the cargo vehicle of various large, medium and small types is in long-time use or after often overload is travelled at present, back axle can produce bending in various degree, can cause other mechanical problem to occur thus, rupture easily as semiaxis, axle shaft screw often fluffs, planet tooth, semiaxis odontotripsis strengthen, and back basin corner gear has abnormal sound, and back axle ruptures and causes vehicle badly damaged or the like when serious.The automobile axle curved detection instrument that I invent can simply, effectively detect distortion, the bending of back axle, and back axle is detected easily owing to the crooked problem that is caused becomes.
Summary of the invention:
For addressing the above problem, I have invented automobile axle curved detection instrument, and the back axle that the purpose of this utility model provides a kind of cargo vehicle to various large, medium and small types carries out the instrument of curved detection.Its principle is: utilize spotlight to produce luminous point, utilize the straight line principle of light to project on the receiving plane on other one side, judge according to the position of luminous point on the receiving plane whether back axle is crooked.This instrument is mainly by among Fig. 1: among emitter (comprising shell body 1, inner housing 2, light-emitting device 3) and Fig. 3: receiving trap 1 is formed.Shell body is used for fixing on back axle, the radial centre lines of inner housing and shell body coexists on the center line, and inner housing can the center line with shell body be that circular motion is made in the center of circle in shell body, the center of inner housing is equipped with light-emitting device, light-emitting device is used for producing luminous point, the luminous point ejaculation that is in line, and concentric with the center line of shell body and inner housing.Its embodiment is: shell body is fixed on the axle tube or back axle wheel hub of back axle, automobile axle curved detection instrument is kept with one heart with the center line of the axle tube that connects, the luminous point that light-emitting device penetrates follows the axle tube of automobile axle to be in a center line together at transmitting terminal, luminous point is mapped to the axle tube center of back axle another side along automobile axle inside, project that (transparent plastic is made on the measurement face of receiving trap among Fig. 3, scale is arranged above), if the center line of back axle is a straight line, luminous point is incident upon the central point of measurement face high scale, if back axle has bending, the deviation that the luminous point of projection produces on scale is exactly the flexibility of back axle.
The technical scheme that its technical matters that solves the utility model adopts is:
Utilize spotlight to produce luminous point, utilize the straight line principle of light to project on the receiving plane on other one side, judge according to the position of luminous point on the receiving plane whether back axle is crooked.This instrument is mainly by among Fig. 1: among emitter (comprising shell body 1, inner housing 2, light-emitting device 3) and Fig. 3: receiving trap 1 is formed.Shell body be used for fixing on back axle (fixed form has two kinds: the 1st, the internal thread by shell body is fixed on the external thread of axle tube of automobile axle.The 2nd, be fixed on the axle shaft screw on the back axle wheel hub by the screw on the shell body, such benefit is not need to dismantle the bending that back axle wheel hub and tire just can detect back axle).The radial centre lines of inner housing and shell body coexists on the center line, and inner housing can the center line with shell body be that circular motion is made in the center of circle in shell body, the center of inner housing is equipped with light-emitting device, light-emitting device is used for producing luminous point, the luminous point ejaculation that is in line, and concentric with the center line of shell body inner housing.Its embodiment is: shell body is fixed on the axle tube or back axle wheel hub of back axle, the luminous point that light-emitting device penetrates follows the axle tube of automobile axle to be in a center line together at transmitting terminal, luminous point is mapped to the axle tube center of back axle another side along automobile axle inside, project on the measurement face of receiving trap among Fig. 3 (transparent plastic making), if the center line of back axle is a straight line, luminous point is incident upon central point on the measurement face, if back axle has bending, the luminous point of projection is exactly the flexibility (Fig. 6) of back axle in the deviation that measurement face produces.Inner housing and shell body be designed to inner housing outside enclosure interior be that the effect that the circumference rotation is done in the center of circle is around the center line of shell body: under the motionless situation of shell body, rotation one week of inner housing, if the luminous point of light-emitting device emission is on the center line of shell body and inner housing, the measurement face that luminous point projects receiving trap among Fig. 3 all the time can be in (the center position on the measurement face of receiving trap in Fig. 3 not necessarily on the same point, but one week of rotation inner housing is motionless as long as luminous point is in any point on measurement face, can prove that it is on same center line that luminous point is followed shell body and inner housing) so the such design of inner housing two effects are just arranged, whether an effect is: detect luminous point and be on the center line of shell body and inner housing, if luminous point has deviation, can adjust light-emitting device and make luminous point follow the center line of shell body and inner housing to be consistent.The another one effect is: if the fixed form of shell body is to be fixed on the external thread of axle tube of back axle, can rotates inner housing and see that luminous point projects the crooked situation that back axle is judged in position on the measurement face of receiving trap among Fig. 3.(if shell body is to be fixed on just can rotate the back axle wheel hub on the axle shaft screw of back axle wheel hub and do not need to rotate inner housing)
The beneficial effects of the utility model are:
Can detect the degree of crook (and not needing to dismantle back axle wheel hub and tire) of back axle fairly simple, easily, make detection easily because the problem that the back axle bending is caused becomes.
