Description

Technical Field

[0001] The utility model discloses an integrated steering knuckle of an unmanned pure electric wide-body dump truck for mining, belonging to the technical field of engineering machinery. Background Art

[0002] In recent years, with the rapid maturity and widespread application of unmanned driving control technology, many mining companies at home and abroad are gradually integrating this technology into their production sequence. Especially abroad, many mining companies are also actively promoting and applying unmanned driving technology. Although unmanned driving technology has been applied to existing large-tonnage mining vehicles, these vehicles are still equipped with high-power traditional engines, which consume huge amounts of diesel and cause serious environmental pollution problems.

[0003] Under the current energy crisis and environmental protection pressure, people's increasing awareness of environmental protection has promoted the development trend of unmanned and pure electric mining vehicles completely replacing traditional mining vehicles. This is not only the only way out for industrial development, but also a key link for mining companies to achieve sustainable development.

[0004] At present, pure electric wide-body dump trucks do not have a systematic electric drive axle. Most vehicles still continue the traditional rigid axle structure, which results in the space layout of pure electric wide-body dump trucks occupying nearly half the length of the vehicle body compared to vehicles with double rear axles or multiple axles. In addition, in terms of the configuration of the power system, these vehicles simply replace the traditional engine system with an electric motor, battery pack and related systems, and retain the gearbox and total transmission system of the traditional model. Therefore, the configuration capacity of the battery system is limited, and the vehicle's range cannot be increased by increasing the battery capacity. Summary of the invention

[0005] Purpose of the invention: To solve the above-mentioned technical problems, the utility model provides an integrated steering knuckle of an unmanned pure electric wide-body mining dump truck, which integrates a drive motor, a reducer and a braking device, and sets the steering installation area and the frame connection area on the outer circumferential surface of the steering knuckle shell, thereby providing sufficient space for configuring a large-capacity battery pack, and is suitable for pure electric wide-body mining dump trucks weighing more than 100 tons.
