Abstract
The utility model relates to a mileage testing device placed on a special detection vehicle for a pavement, belonging to the technical field of pavement condition detection equipment. The mileage testing device comprises a rotating shaft (6), a rotating speed connector (1) arranged at one end of the rotating shaft (6) and butted with a rotating speed output shaft of a vehicle gear box, a vehicle speed sensor arranged at the middle of the rotating shaft (6), a coupler (7) arranged at the other end of the rotating shaft (6) and a mileage testing coder (5) connected with the coupler (7), wherein the vehicle speed sensor comprises an annular magnet (2), a Hall element (3) and a cable socket (4), and are detachable parts of an electromagnetic pulse type vehicle speed sensor of an original vehicle. The mileage testing device has the advantages of simple structure, one-step installation, long service life, simplicity in maintenance, practicability and convenience; and the mileage testing device is capable of enabling the function of the vehicle speed sensor of the original vehicle to be unchangeable and giving consideration to the testing of mileage of the special detection vehicle for the pavement, thereby having two functions.
Description
Technical field:
The utility model relates to a kind of mileage proving installation that places on the dedicated test car of road surface, belongs to highway road conditions checkout equipment technical field.
Background technology:
Various a series of data that the dedicated test car test of various road surfaces is surveyed all need be by the mileage record of each data at tested route, to distinguish the accurate position of each data.What the mileage proving installation of road surface dedicated test car generally adopted at present is: scrambler test travel distance or mileage are installed in the outside, rear wheel axle center at the dedicated test car, when being each the detection, this method to manually install, need remove scrambler again after having detected, using is not to make things convenient for very much.And owing to be installed in the outside, rear wheel axle center, increased the car load width, brought driving safety hidden danger.Because rear wheel vibrates with the fluctuations on road surface in motion, the scrambler that is installed on the rear wheel reduces serviceable life because of vibration in addition.
The vehicle speed sensor that present vehicle generally uses is the electromagnetic pulse formula, test philosophy is similar substantially to scrambler, but the measuring resolution of the measuring resolution of vehicle speed sensor and road surface dedicated test car scrambler differs too many, the measuring resolution of road surface dedicated test car scrambler requires to reach 1mm, and both supply voltage differences can not be used with or substitute.
For the mileage proving installation that overcomes existing road surface dedicated test car is installed and used, safety and the deficiency in serviceable life, provide the utility model.By literature search, do not see the open report identical with the utility model.
Summary of the invention:
The purpose of this utility model is to overcome that the mileage proving installation of existing road surface dedicated test car is installed and used, safety and the deficiency in serviceable life, and a kind of mileage proving installation that places on the dedicated test car of road surface is provided.
The utility model adopts the electromagnetic pulse formula vehicle speed sensor of former vehicle; Be combined into one with vehicle speed sensor and scrambler, as the mileage proving installation of road surface dedicated test car.
The mileage proving installation that places on the dedicated test car of road surface of the present utility model, by rotating shaft (6), the rotating speed connector (1) that places rotating shaft (6) one ends to dock with the vehicle gear box rotating speed output shaft, place the vehicle speed sensor by toroidal magnet (2), Hall element (3) and cable socket (4) formation at rotating shaft (6) middle part, place the shaft joint (7) of rotating shaft (6) other end, the mileage test encoder (5) that is connected with shaft joint (7) is formed; Wherein: toroidal magnet (2), Hall element (3) and cable socket (4) are the electromagnetic pulse formula vehicle speed sensor dismounting parts of former vehicle, are installed in the utility model.
The material that parts of the present utility model adopt market to buy product or market purchase is reequiped according to a conventional method or is prepared.
Of the present utility modelly place the mileage proving installation on the dedicated test car of road surface to be installed on the inspection vehicle wheel box.The former car vehicle speed sensor that requires inspection vehicle is the electromagnetic pulse formula of generally using at present, is not suitable for old-fashioned mechanical cable type.
Advantage of the present utility model is: simple in structure, one-step installation, long service life, safeguard simple, practical and convenient; After the vehicle gear box rotating speed output shaft is installed, can make former car vehicle speed sensor function constant, can take into account road surface dedicated test car kilometer test again, one is dual-purpose.
Description of drawings:
Fig. 1 is the utility model structural representation
Fig. 2 uses synoptic diagram for the utility model.
Embodiment:
The mileage proving installation that places on the dedicated test car of road surface of the present utility model, by rotating shaft 6, the rotating speed connector 1 that places rotating shaft 6 one ends to dock with the vehicle gear box rotating speed output shaft, place the vehicle speed sensor that is constituted by toroidal magnet 2, Hall element 3 and cable socket 4 at rotating shaft 6 middle parts, place the shaft joint 7 of rotating shaft 6 other ends, the mileage test encoder 5 that is connected with shaft joint 7 is formed; Wherein: toroidal magnet 2, Hall element 3 and cable socket 4 are the electromagnetic pulse formula vehicle speed sensor dismounting parts of former vehicle, are installed in the utility model.
The material that parts of the present utility model adopt market to buy product or market purchase is reequiped according to a conventional method or is prepared.
Of the present utility modelly place the mileage proving installation on the dedicated test car of road surface to be installed on the inspection vehicle wheel box by docking with the vehicle gear box rotating speed output shaft.The former car vehicle speed sensor that requires inspection vehicle is the electromagnetic pulse formula of generally using at present, is not suitable for old-fashioned mechanical cable type.
Embodiment of the present utility model is:
Of the present utility modelly place mileage proving installation on the dedicated test car of road surface to dock with the vehicle gear box rotating speed output shaft by connector 1 to be installed on the inspection vehicle wheel box, drive toroidal magnet 2 and scrambler 5 rotations through rotating shaft 6, the magnetic pole of Hall element 3 test toroidal magnets 2, produce electromagnetic pulse signal, the cable transmission through being connected in cable socket 4 is to speedometer.The photoelectric pulse signal that scrambler 5 produces through cable transmission to checkout equipment.
Practical application shows that the utility model reaches designing requirement fully.
