Description
Technical Field
The utility model relates to a vehicle steering system especially relates to a heart dish device among large-scale heavy-duty metallurgical haulage vehicle steering system.
Background
The core disc device is a connecting piece of a metallurgical transport vehicle body and a bogie, and the vertical load of the vehicle body is transmitted to the bogie through the core disc device when the vehicle runs. The core plate device is generally composed of an upper core plate, a lower core plate and core plate pins, wherein the upper core plate and the lower core plate form a convex-concave fit, and the core plate pins penetrate through the upper core plate and the lower core plate. The upper center plate is connected with the vehicle body, and the lower center plate is connected with the bogie. The function of the device is to transfer the weight of the vehicle carrying goods to wheels, reduce the running resistance of the vehicle and also coordinate the horizontal angle change error and the vertical angle change error of the vehicle body and the bogie when the vehicle passes through a curve. When the angle of the vehicle body changes in the horizontal direction, the upper center plate and the lower center plate rotate relatively; when the angle of the vehicle body changes in the vertical direction, the upper center plate and the lower center plate are inclined relatively; when the vehicle is started and braked, the upper center plate and the lower center plate move. Therefore, the core plate device bears the vertical load and the horizontal load of the vehicle and the friction force between the upper core plate and the lower core plate, so that the core plate device is one of the key components of the vehicle.

The existing metallurgical transport vehicle basically uses a plane center plate device, and the upper center plate and the lower center plate of the plane center plate device are both disc-shaped. The upper core plate and the lower core plate are made of cast steel, and the core plate pin is made of Q345 steel.

The above problems are particularly acute with the mandrel devices of heavy duty metallurgical transport vehicles. In metallurgical plants, the terrain is complex, the curve radius of the line is small, the speed of the vehicle must be reduced, and the vehicle is difficult to pass through, so that derailment is easy to cause. Practice proves that the plane core disc device has severe abrasion of the core disc and poor use effect due to severe operation environment and poor lubricating effect.
