Specific embodiment
Present invention will be further explained below with reference to specific examples.It should be understood that these embodiments are merely to illustrate the present invention
Rather than it limits the scope of the invention.In addition, it should also be understood that, after reading the content taught by the present invention, those skilled in the art
Member can make various changes or modifications the present invention, and such equivalent forms equally fall within the application the appended claims and limited
Range.
As shown in figures 1 to 6, the technical solution adopted by the present invention to solve the technical problems is: it is close to provide a kind of automobile
Angle, departure angle and ramp breakover angle measuring device, including angle measurement equipment 1 and angular adjustment swing arm 2, the angle surveys
Measuring device 1 is mounted on the outer side center position of the opposite wheel in automobile two sides, the shaft and angular adjustment of the angle measurement equipment 1
One end of swing arm 2 is connected, and the other end of the angular adjustment swing arm 2 extends to the edge of wheel and the angle tune of two sides
It is connected with transmitting light belt 3 between section swing arm 2, is provided with angular adjustment component 4 on the downside of wheel, the angular adjustment component 4 packet
It includes pedestal 41, is rotatedly connected on 41 side wall of pedestal with one end of oscillating rod 42, the other end axis of the oscillating rod 42
To being equipped with driving nut 43 and lead-screw 44 inserted with axial movement, one end of the lead-screw 44 and angle tune
One end side wall of section swing arm 2 is rotatedly connected.
The light that the transmitting light belt 3 projects is tangent with the excircle side wall of wheel always, the light that transmitting light belt 3 projects
Line is a straight ray.
The angular adjustment swing arm 2 is made of two swing arms, the sliding slot phase between two swing arms by axially arranging
Even, to adjust the length of angular adjustment swing arm 2.
Further include the light receiver wall 5 that automobile front side or rear side are set, is provided with angle on the angle measurement equipment 1
Spend display screen.
As the embodiment of the present invention:
As shown in figure 4, close to angular measurement: the vehicle of measurement is faced into light receiver wall 5 and is parked, with light receiver wall 5 it
Between distance be 50cm, be respectively mounted on two front vehicle wheels of vehicle angle measurement equipment 1, angular adjustment swing arm 2, transmitting light belt 3
With angular adjustment component 4, while adjust angle measurement equipment 1 make when angular adjustment swing arm 2 is perpendicular to the ground the left and right sides angle
Spending indicating value is 0, and the light that transmitting light belt 3 issues can be irradiated on the light receiver wall 5 of front, then passes through rotate driving spiral shell
Mother 43 can be such that lead-screw 44 moves axially, and angular adjustment swing arm 2 is pushed to be swung, and position is gradually increasing, hair
The light for penetrating the injection of light belt 3 is tangent with the excircle side wall of wheel always, horizontal light on light receiver wall 5 can always on
It moves, when some critical value, breakpoint occurs in the light on light receiver wall 5, then the indicating value of angle measurement equipment 1 is vapour at this time
The approach angle of vehicle.
As shown in figure 5, the measurement of departure angle: the vehicle of measurement being parked backwards to light receiver wall 5, with light receiver wall 5
The distance between be 50cm, be respectively mounted on two rear wheels of vehicle angle measurement equipment 1, angular adjustment swing arm 2, transmitting light belt
3 and angular adjustment component 4, the method for measurement it is consistent with the measurement method of approach angle above.
As shown in fig. 6, the measurement of ramp breakover angle: needing 1 people on ground at the ground for having melt pit, measurement vehicle parking
In hole, in addition 1 people is in ground operating equipment, while using above-mentioned two sets of measuring devices, emits the direction of the launch of light belt 3 to vehicle
In the middle part of chassis, vehicle bottom is regarded into light receiver wall, light infall of two sets of equipment at vehicle bottom is ramp breakover angle
The position at place, the sum of numerical value of angle measurement equipment 1 of two sets of equipment are ramp breakover angle.
Table 1, actual measurement data
Recommend tire pressure using tire pressure when measurement for vehicle, tire is factory tire, and theoretical value is calculated by design, not
The factors such as deformation of tire in actual use are considered, so comparatively numerical value bigger than normal (namely can be biased to vehicle to pass through
Property better direction), and measured value is the numerical value that actual measurement goes out, closer to real use state, more really.
The configuration of the present invention is simple, it is easy to install and use, can be used for measuring three kinds by angle, abandoned it is original with ruler into
Capable indirect measurement, but the direct measurement that light projects is used, it is more accurate without the calculating in later period, it can also be applicable in
In different types of vehicle, there is good promotional value.
