AI Technical Summary
Existing angle sensors are prone to zero-point drift faults in mining dump trucks, which are complicated to repair and affect vehicle operating time.
The angle sensor is placed on the outside of the steering mechanism. The steering mechanism drives the sensor to rotate around the kingpin. The angle sensor connector is connected to the kingpin. Combined with the cover plate and bushing design, the maintenance process is simplified.
This avoids damage to the angle sensor and zero-point drift, improving the convenience of maintenance and the reliability of the mechanical structure.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of vehicle axle technology, specifically to an arrangement structure for a steering axle angle sensor, applicable to steering axle assemblies using angle sensors. Background Technology
[0002] With the continuous development of mining dump trucks, unmanned mining dump trucks are becoming increasingly common. The steering axle assembly needs to be equipped with an angle sensor to detect the turning angle and enable the system to control the vehicle. Currently, most angle sensors are located inside the kingpin; due to the harsh road conditions in mining areas, zero-point drift failure of the angle sensor often occurs; during maintenance, the angle sensor often requires the removal of the top cover and auxiliary parts, which is a cumbersome disassembly and assembly process, seriously delaying time and shortening vehicle operating time. Utility Model Content
[0003] The purpose of this invention is to overcome the problems existing in the prior art and to provide an arrangement structure for a steering axle angle sensor.
[0004] The technical solution provided by this utility model is: an arrangement structure for a steering axle angle sensor, characterized in that it includes an angle sensor, an angle sensor bracket, an angle sensor connector, a cover plate, a kingpin seat, a brass bushing, a kingpin, and a steering device; the angle sensor bracket is connected to the cover plate; the angle sensor is connected to the angle sensor bracket and inserted into the angle sensor connector; the angle sensor connector is fixed above the kingpin; the cover plate is connected to the kingpin seat, and the kingpin seat is installed on the steering device; the kingpin is connected to the cover plate; a brass bushing is provided between the kingpin and the kingpin seat; the steering device drives the angle sensor to rotate around the kingpin.
[0005] Furthermore, an oil seal is provided on the cover plate.
[0006] The beneficial effects of this utility model are:
[0007] 1. The steering angle sensor is located on the outside of the steering device, which avoids steering angle adjustment and makes the maintenance and replacement of the steering angle sensor difficult;
[0008] 2. The main pin and the angle sensor are connected through an angle sensor connector, which has a reliable mechanical structure and strong anti-interference ability. Attached Figure Description

[0011] To better understand and implement this invention, the following detailed description is provided in conjunction with the accompanying drawings.
[0012] like Figure 1 As shown, an arrangement structure for a steering axle angle sensor includes an angle sensor 1, an angle sensor bracket 2, an angle sensor connector 3, an oil seal 6, a cover plate 7, a kingpin seat 12, a brass bushing 13, a kingpin 16, and a steering device 17.
[0013] The angle sensor bracket 2 and the cover plate 7 are fixedly connected by the first bolt 4 and the first spring washer 5. The angle sensor 1 is connected to the angle sensor bracket 2 and inserted into the angle sensor connector 3. The angle sensor connector 3 is fixed above the main pin 16 by the third bolt 14 and the second spring washer 15. After the cover plate 7 and the main pin seat 12 are connected by the second bolt 8, the main pin seat 12 is installed on the steering device 17. A nylon pad 11, an adjusting pad 10 and a rubber pad 9 are installed between the main pin 16 and the cover plate 7 to control the overall up and down movement. A brass bushing 13 is installed between the main pin 16 and the main pin seat 12 to control the amount of wear. The steering device 17 drives the angle sensor 1 to rotate around the main pin 16. An oil seal 6 is installed on the cover plate 7 to prevent dust and seal grease.
[0014] This utility model discloses an arrangement structure for a steering axle angle sensor. The angle sensor is externally mounted and rotates around the kingpin via the steering device to achieve angle measurement. This avoids the problem of difficult maintenance after the angle sensor is damaged or drifts at the zero point. It also has the advantages of simple structure, convenient maintenance, and high reliability. With the continuous development of unmanned mining dump trucks, the application of angle sensor arrangement will become more and more widespread.
