Description

Lubrication system, distributor and vehicle

Technical field

Embodiments of the present disclosure belong to the field of autonomous driving technology, and specifically relate to a lubrication system, a distributor and a vehicle.

Background technique

As driverless technology continues to mature, driverless wide-body transport vehicles have appeared in the public eye and are operating on a regular basis in the mining transportation industry. As an intelligent vehicle, it saves manpower and reduces labor costs. However, there are still problems such as high manual labor intensity, low operating efficiency and unguaranteed work quality in terms of maintenance, especially in the operation of replenishing grease to the vehicle.

Unmanned wide-body transport vehicles are heavy-duty vehicles, and most of the kinematic pairs of their steering, braking, suspension and cargo box lifting systems are sliding friction type kinematic pairs. In order to extend the service life of the vehicle, an oil filling hole will be installed in a certain area of the moving pair to add grease and keep the moving pair lubricated.

Due to the objective requirements of transportation scenarios, driverless vehicles usually drive on bumpy and rugged roads, with frequent movements and violent impacts of the moving pairs. In this case, if the lubrication is not in place, the wear of the moving pairs will be accelerated and the vehicle life will be greatly shortened. In addition, since the grease will gradually dry out as the vehicle is used, it needs to be replenished regularly.

At present, major mining areas at home and abroad have formulated vehicle lubrication plans, which currently include manual lubrication and centralized lubrication. Among them, the manual lubrication method requires a person to hold a grease filling gun and add grease to each lubrication point of the vehicle one by one. This method requires a large workload, and the quality and efficiency of refilling are restricted by factors such as the personnel's technical proficiency and emotions, which can easily cause Add missing questions. In the centralized lubrication method, the grease in the fuel tank is pressurized through a grease pump, and then pumped into the distributor, and then distributed to various lubrication points through pipelines. This method is prone to waste of grease, and excessive grease spills on the vehicle surface and The ground affects the appearance and causes certain pollution.
