Automatic steering integrated control device of fire engine

Abstract

The invention relates to an automatic steering integrated control device of a fire engine. The automatic steering integrated control device comprises a steering rod, a gear transmission mechanism, an oil storage tank, an oblique support and a limit support mechanism, wherein, the gear transmission mechanism comprises a transition sleeve with a shaft shoulder, a gear connecting plate, a steering rod gear, a transition gear and a motor; the transition sleeve is fixed on the steering rod; the steering rod gear is arranged on the transition sleeve; the gear connecting plate is sheathed on the transition sleeve and can relatively rotate; a transition shaft and the motor are arranged on the gear connecting plate; the steering rod gear is meshed with a driving gear on the motor through the transition gear arranged on the transition shaft; the oil storage tank is arranged on the bottom surface of the gear connecting plate and is hermetically connected with the steering rod; the limit support mechanism comprises a limit rod and more than two support rods which are arranged on the oblique support; a guide rod is arranged in a limit slot of the gear connecting plate; and the support rods prop against the bottom of the gear connecting plate. The automatic steering integrated control device has the advantage that the engagement position of a drive gear pair does not need to be adjusted after a head frame is maintained, thus keeping transmission efficiency.

Description

technical field [0001] The invention relates to an integrated control device for automatic steering of a fire truck, which belongs to the technical field of automatic steering control of motor vehicles. Background technique [0002] Fire-fighting vehicles are mobile equipment that perform fire-fighting, auxiliary fire-fighting and emergency rescue tasks, and transport personnel, fire-fighting equipment or fire-fighting supplies. Although there are many types of fire-fighting vehicles, fire-fighting vehicles are mainly composed of two parts: vehicle chassis and fire-fighting equipment. The chassis of a fire truck is the same as a conventional motorized chassis, consisting of a transmission system, a steering system, a braking system and a driving system. The transmission system is mainly composed of a clutch, a gearbox, and a rear axle. The torque of the engine is transmitted through the transmission system, and the magnitude of the transmitted torque and speed is changed, so...

AI Technical Summary

Problems solved by technology

However, since the steering rod bevel gear and the motor are respectively installed on the steering rod and the inclined bracket, there is no uniform installation reference, and the steering rod has some slight swings when it turns, which makes it difficult to mesh the gears.

In addition, when the head frame of the fire engine is being repaired, it needs to be turned over. At this time, the steering rod should also swing with the head frame. Since the gear mesh is a separate structure, it is necessary to adjust the working position of the motor after maintenance to ensure that the transmission gear pair This not only increases the maintenance and adjustment time, but also cannot guarantee the meshing position of the transmission gear pair after maintenance, resulting in early wear of the transmission gear pair and a decrease in transmission efficiency, which shortens the service life of the automatic steering device

Moreover, since the automatic steering device does not consider the lubrication of the transmission gear pair, the transmission gear pair has a large frictional resistance, which not only accelerates the wear of the transmission gear pair, but also because of the large transmission resistance between the transmission gear pairs, reduce transmission efficiency
