Accurately tested the speed.
To achieve the above object, the utility model provides following technical scheme：
A kind of vehicle speed measuring device, including code-disc and tachogenerator, the code-disc are arranged on vehicle gear box output shaft
With the junction of power transmission shaft, the tachogenerator is arranged on the side of code-disc, and the tachogenerator passes through sensor stand
It is fixedly mounted on vehicle frame, the mounting distance between the tachogenerator and code-disc is 2-5mm.
As further scheme of the present utility model, the mounting distance between the tachogenerator and code-disc is 4mm.
As further scheme of the present utility model, the tachogenerator is exported using Hall pulse square wave.
As further scheme of the present utility model, 4 mounting holes are provided with the inside of the code-disc, the mounting hole is with passing
The location hole of moving axis is corresponding to be installed.
As further scheme of the present utility model, in addition to mileometer, the mileometer is connected with tachogenerator.
The beneficial effects of the utility model are：
The utility model installs code-disc in the junction of vehicle gear box output shaft and power transmission shaft, sets and surveys in code-disc side
Fast sensor, tachogenerator connection mileometer, by being used cooperatively for tachogenerator and code-disc, is accurately surveyed to vehicle
Speed, it is simple in construction, it is easy to use；4 mounting holes, mounting hole peace corresponding with the location hole of power transmission shaft are provided with the inside of code-disc
Dress, tachogenerator are fixedly mounted on vehicle frame by sensor stand, firmly installed, convenient disassembly；Tachogenerator and code
Mounting distance between disk is preferably 4mm, does not have interference and test error very little in the case of vehicle normal operation.
Brief description of the drawings
Fig. 1 is the overall structure diagram of vehicle speed measuring device of the present utility model；
Fig. 2 is code-disc structural representation of the present utility model.
In accompanying drawing：1- output shafts, 2- power transmission shafts, 3- code-discs, 31- mounting holes, 4- tachogenerators, 5- sensor stands,
6- vehicle frames.
Embodiment
In order that those skilled in the art more fully understand the technical solution of the utility model, with reference to of the present utility model
Accompanying drawing, clear, complete description is carried out to the technical solution of the utility model, it is general based on the embodiment in the application, this area
Other similar embodiments that logical technical staff is obtained on the premise of creative work is not made, should all belong to the application
The scope of protection, in addition, the direction word mentioned in following examples, such as " on " " under " " left side " " right side " etc. is only refer to the attached drawing
Direction, therefore, the direction word used is for illustrative and not limiting the invention.
As depicted in figs. 1 and 2, a kind of vehicle speed measuring device, at vehicle gear box, including code-disc 3, test the speed sensing
Device 4 and mileometer (not shown), the code-disc 3 are arranged on the junction of vehicle gear box output shaft 1 and power transmission shaft 2, institute
State the inner side of code-disc 3 and be provided with 4 mounting holes 31, the mounting hole 31 peace corresponding with the location hole (not shown) of power transmission shaft 2
Dress, it is ensured that power transmission shaft 2 drives code-disc 3 to rotate, and the tachogenerator 4 is arranged on the side of code-disc 3, the tachogenerator 4
It is fixedly mounted on by sensor stand 5 on vehicle frame 6, the sensor stand 5 is fixedly mounted on vehicle frame 6 using bolt, is torn open
Dress is convenient, and the mounting distance between the tachogenerator 4 and code-disc 3 is 2-5mm, it is preferable that the tachogenerator 4 and code
Mounting distance between disk 3 is 4mm, does not have interference and test error very little, the survey in the case of vehicle normal operation
Fast sensor 4 is connected with mileometer, and the information that will test the speed hair should be easy to human pilot to observe, due to work to showing on mileometer
For speed than relatively low, the rotating speed of code-disc 3 is relatively low during the truck operation of ground, therefore higher to the sensitivity requirement of mileometer, it is necessary to short
When interior progress step-by-step counting union speed, because truck vibration is big, building site bad environments, the tachogenerator 4 is using suddenly
You export pulse square wave, it is specified that accuracy of measurement is high in scope.
The utility model is used cooperatively by tachogenerator 4 and code-disc 3, and vehicle is accurately tested the speed, has structure
Simply, the characteristics of easy to use.
It is obvious to a person skilled in the art that the utility model is not limited to the details of above-mentioned one exemplary embodiment, and
And in the case of without departing substantially from spirit or essential attributes of the present utility model, it can realize that this practicality is new in other specific forms
