Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a driving and power limiting apparatus for an over-

In order to monitor the axle load and the gross weight of the vehicle, the present invention is constructed and constructed as a driving and output restriction device and a load measuring device for preventing overload and gross weight from exceeding, thereby reducing the damage to the road A load measuring device capable of applying a sensor capable of measuring the load of a vehicle such as a leaf spring angle sensor attached to a leaf spring, an air suspension pressure sensor, a load cell, etc., And the measured value by the load measuring device is compared with the actual load weight so that when the measured value by the load measuring device exceeds the reference value of the axial load or gross weight, it is forcibly operated (started) through the controller of the output limiting device The output can be limited or the output can be limited. The data obtained by measuring the load and gross weight through the load measuring device (OBD: on-board diagnostics (OBD)) of the operation and output limiter unit when the load measuring unit detects the overload or the total weight of the vehicle exceeds the reference value. ), It is possible to control the operation and output restriction through the controller of the operation and output restriction device and to detect whether or not the device for preventing the overload and the total weight from exceeding is arbitrarily removed, Quot; is a technique relating to running and output limiting devices for overweight, over-weight vehicles that allow starting from idling or taking idling action.

Recently, in a freight vehicle, a variable shaft equipped with an auxiliary tire may be used as a suspension device. Further, the variable shaft includes a tag axle, a pusher axle, and a lifting axle, and is provided so as to be able to move up and down, thereby dispersing the entire load of the freight car if necessary.

For example, when there is no cargo loaded on the freight vehicle equipped with the variable shaft, that is, when the cargo is free, the variable shaft is raised to prevent the auxiliary tire from touching the ground, That is, when the car is loaded, the variable shaft is lowered so that the auxiliary tire supports the ground, so that the entire load of the freight vehicle can be distributed in a balanced manner.

An air spring is mounted to move the variable shaft upward and downward. The air spring is located between the variable shaft and the vehicle body of the freight vehicle. The compressed air enlarges or conversely reduces the volume of the variable shaft, Up and down. At this time, a plurality of air springs including a lift air spring and a fall air spring may be provided.

In addition, it is also possible to provide a pressure switch capable of controlling the upward / downward movement of the variable shaft by the air spring or the pressure of the air spring by providing the variable shaft switch so that the driver of the freight vehicle can arbitrarily adjust the pressure of the air spring Respectively.

The driver of the freight vehicle can not accurately know the load actually applied, so that the freight can be unintentionally loaded in the overload state and the safety of the freight vehicle is threatened when traveling.

In addition, Article 79 (2) of the Enforcement Decree of the Road Act stipulates that, in order to conserve the road structure and to prevent the risk of driving the vehicle on the road, the congestion load exceeds 10 tons or the total weight is 40 tons Excessive vehicles are limited on roads, and the effect of the 11-ton traffic on the road pavement on the road pavement, such as the traffic of 110,000 passengers, is also listed in the Ministry of Land, Transport and Communications official directive No. 799 .

However, shippers and freight forwarders are required to pay for the overhaul (load reduction) of the vehicle for the economic benefit (reduction of transportation cost, reduction of fuel cost, reduction of vehicle maintenance cost, attracting customers) Or a "variable shaft" mounted on the vehicle), which is a cause of large-scale traffic accidents due to road breakage and a decrease in braking force. Therefore, fundamental measures for improvement are urgent.

Therefore, a device for preventing overload and gross weight from being exceeded to monitor the axle load and gross weight of the vehicle is constituted by a running and output limiting device and a load measuring device, and applied to the running vehicle to reduce the damage of the road, A load measuring device capable of applying a sensor capable of measuring the load of a vehicle such as a leaf spring angle sensor attached to a leaf spring, an air suspension pressure sensor, a load cell, etc., When the measured value by the load measuring device compares the measured value with the actual load weight by the load measuring device and limits the operation (start) through the controller of the operation and output limiter when the reference value of the load or gross weight exceeds the reference value, There is a desperate need to develop an output limiting device that is capable of limiting the output, .
