Odometer applied on vehicle axle for metering vehicle-miles of travel

Abstract

The invention discloses an odometer applied on a vehicle axle for metering vehicle-miles of travel. The odometer comprises a shell, a through hole formed in a central position of the shell, a double-screw bolt penetrated in the through hole and matched with the through hole, a self-locking nut matched and connected with the double-screw bolt in a threading manner, a turbine worm mechanism disposed in the central position of the shell and installed inside the shell, a copper sleeve sleeving a worm, a counterweight balancing mechanism connected with the turbine worm mechanism by virtue of the copper sleeve, a turbine shaft penetrating through the central position of a turbine, supporting frames respectively arranged at two ends of the turbine shaft, a ratchet mechanism disposed at one side of the turbine worm mechanism and installed on the supporting frames and a counting mechanism arranged at the bottom end of the turbine worm mechanism and driven by the ratchet mechanism. The odometer not only can provide accurate and intuitive mileage information, but also can solve the problem that the traditional odometer cannot directly meter the mileage of a trailer with no driving speed changer.

Description

technical field [0001] The invention relates to the technical field of a vehicle mileage counting device, in particular to an odometer used for measuring vehicle mileage on a vehicle axle. Background technique [0002] Vehicle mileage is an important basis for vehicle management and vehicle maintenance. Vehicle mileage is one of the most important bases when the fleet formulates vehicle maintenance plans, evaluates vehicle warranty periods, calculates fuel consumption, and rents vehicles or parts costs. . [0003] In order to reflect the mileage traveled by vehicles such as construction machinery and automobiles, an odometer is usually installed in the cab, and the mileage data of the vehicle is obtained by accumulating the rotation of the vehicle. The power of the vehicle engine is transmitted to the gearbox through the crankshaft, and then from the gearbox to the transfer case or final drive, and then to the wheels. However, because the trailers pulled by motor vehicles d...

AI Technical Summary

Problems solved by technology

The power of the vehicle engine is transmitted to the gearbox through the crankshaft, and then from the gearbox to the transfer case or final drive, and then to the wheels. However, because the trailers pulled by motor vehicles do not have gearboxes, mileage information cannot be obtained directly. , resulting in the trailer not being able to accumulatively travel mileage data, affecting regular maintenance and maintenance, thereby reducing the service life of the trailer

[0004] Moreover, the odometer installed on the vehicle generally uses a fixed transmission ratio coefficient for speed measurement and mileage calculation, which leads to a certain deviation between the actual mileage and the displayed mileage of the vehicle, which cannot meet the vehicle's demand for accurate mileage information.
