Abstract
The utility model provides a device for measuring wheelbase of wheels, which is composed of two measuring units. Each unit is connected by a pedal through four steel balls and four force sensors. Each unit can be used for measuring the positions of the wheels which act on the pedal. The wheelbase of the wheels can be obtained according to two position values and a distance between two measuring units. The utility model has the advantages of high durability, long service life, high measuring precision and low price and is suitable for wide popularization and use.
Description
The utility model relates to the measuring instrument in detection technique field, particularly a kind of device that is used for the measurement of automotive wheel wheelspan.
Background technology: the device of measured automobiles vehicle wheel distance is all not mature enough both at home and abroad for a long time, for example France, gondola vehicle wheel adopt the conductive rubber band apart from measurement mechanism, differentiate the position of wheel according to the sense of touch image of wheel on the conductive rubber band, calculate the vehicle wheel distance according to the position of two wheels then.The shortcoming of this device is that the conductive rubber strength at repeated alternation is poor, service life is very short, using about half a year on the express highway and will damaging, must use new conductive rubber band instead usually, and it is a lot of to expend fund.
The purpose of this utility model is to propose a kind of vehicle wheel apart from measurement mechanism, this device adopts two separate units to measure wheel position, each unit is made up of four force gauges, four steel balls and pedal, the center of gravity of wheel application force power on pedal can be measured accurately, the vehicle wheel distance can be calculated according to two data that the unit is surveyed.The technical solution of the utility model is:
A kind of vehicle wheel is apart from measurement mechanism, and it is made of two measuring units, and each measuring unit comprises sensor (1), pedal (2), steel ball (3), base plate (4), it is characterized in that:
Four force gauges (1) are installed on the base plate (4), a hemispheric hole is arranged at the top of each force gauge, respectively there is a steel ball (3) to fasten in the hole, four force gauges (1) and four steel balls (3) are connected with top pedal (2), pedal (2) is made by high-intensity metallic material, and four force gauges (1) can be measured wheel is gone up point of action at pedal (2) position accurately;
Two identical measuring units are placed in together side by side, vehicle two front-wheels or trailing wheel be pressed in respectively on each unit, the distance between the distance that measures according to each wheel and two measuring units just can calculate the vehicle wheel distance.
Described measuring unit can be made of two, three or a plurality of sensor.The beneficial effects of the utility model are:
1. vehicle wheel is durable in use apart from measurement mechanism, the life-span is long, survey precision is high, and cheap, is suitable for extensively promoting the use of.
2. device is stable when adopting four sensor S1, S2, S3, S4, also can adopt two sensors, promptly in measurement mechanism right side and left side each with a sensor, perhaps adopt three sensors, as in a side with two sensors, and at opposite side with a sensor, can realize that all wheelspan measures.
The drawing explanation:
Fig. 1 is the structural representation A and the A1 of wheel center of gravity measurement parts in the device.
The scheme drawing of Fig. 2 to be vehicle wheel measure in measurement mechanism vehicle wheel distance.
Be described in further detail below in conjunction with its principle of work of description of drawings and to the utility model embodiment.
This device is made up of two identical unit of M1, M2, and each unit is linked to each other with pedal 2 by four steel balls 3 by four force gauges 1, and base plate 4 can be considered ground, and its arrangement plan is shown in figure one, and Figure 1A is the device front view, and Figure 1A 1 is the device birds-eye view.
Each measuring unit constitutes by four jiaos of four force gauge S1, S2, S3, S4 and pedals 2 of arranging of oblong by four, contact by steel ball 3 between pedal 2 and four force gauge S1, S2, S3, the S4, four hemispherical-shaped aperture are arranged on pedal 2, simultaneously at four force gauge S1, S2, S3, S4 onesize spherical pore is arranged also, four steel balls are placed between upper and lower two hemispherical-shaped aperture and fasten.
When a wheel was arranged on the pedal 2, the weight of car produced application force, the position that can measure wheel point of action on pedal 2 by four force gauges 1 accurately by wheel through pedal 2 and 3 pairs of four sensors of four steel balls 1.
If the center of effort of wheel is X from the distance of measurement mechanism one end, following relational expression is arranged then: total weight G=G1+G2+G3+G4, wherein G1, G2, G3, G4 are respectively the power that sensor S1, S2, S3, S4 measure.If the distance in the pedal 2 between two steel balls 1 is B, G * X=(G3+G4) * B then, thus X=B * (G3+G4)/G.Can measure L1 and L2 with above-mentioned way,
The scheme drawing of Fig. 2 to be vehicle wheel measure in measurement mechanism vehicle wheel distance.The left side of the right side of measuring unit M1 and measuring unit M2 is adjacent among the figure, and its distance is D, and D is a fixed value for already installed device.
If it is L1 that the point of action of vehicle revolver is measured distance, the point of action of the right wheel of vehicle is L2 from the distance of measuring unit, and then vehicle wheel is apart from L=L1+L2+D
Wherein: L1=B (G1+G2)/(G1+G2+G3+G4)
L2=B(G'3+G'4)/(G'1+G'2+G'3+G'4)
When obviously adopting four sensor S1, S2, S3, S4, the device pedal is more stable.But also can adopt two sensors, promptly each perhaps adopts three sensors with a sensor in measurement mechanism right side and left side, as in a side with two sensors, and at opposite side with a sensor, all can realize the wheelspan measurement.
Claims (2)
1. a vehicle wheel is apart from measurement mechanism, and it is made of two measuring units, and each measuring unit comprises sensor (1), pedal (2), steel ball (3), base plate (4), it is characterized in that:
Four force gauges (1) are installed on the base plate (4), a hemispheric hole is arranged at the top of each force gauge, respectively there is a steel ball (3) to fasten in the hole, four force gauges (1) and four steel balls (3) are connected with top pedal (2), pedal (2) is made by high-intensity metallic material, can measure wheel is gone up point of action at pedal (2) position accurately by four force gauges (1);
Two identical measuring units are placed in together side by side, when vehicle two front-wheels or trailing wheel when being pressed on each unit respectively, the distance between the distance that measures according to each wheel and two measuring units just can calculate the vehicle wheel distance.
2. a kind of vehicle wheel according to claim 1 is apart from measurement mechanism, it is characterized in that described measuring unit can be made of two, three or a plurality of sensor.
