摘要： The lubricant level within a reservoir is difficult to monitor, leading to the reservoir being refilled more often than necessary to ensure that the reservoir always contains lubricant. A lubricant level sensing system is connected to and monitors various aspects of the pump assembly that draws lubricant from the reservoir. The pump assembly displaces a known volume of lubricant with each pump stroke. A lubricant-level estimator calculates an estimated lubricant level remaining in the reservoir based on a stroke-count value as sensed from the pump assembly and on a reference value stored in a memory. The estimated lubricant level provides the lubricant remaining and the rate of usage such that maintenance can be scheduled ahead of time to prevent the reservoir running dry.

摘要： A vehicle lubrication system includes a plurality of sensors disposed on the vehicle and configured to sense operational characteristics of the vehicle, a pump disposed on the vehicle and configured to deliver lubricant to a plurality of lubricated regions of the vehicle, and a controller device operatively coupled to the pump. The controller device is configured to receive sensor data corresponding to the operational characteristics of the vehicle sensed by the plurality of sensors, and determine, based on the received sensor data, a lubricant delivery frequency at which lubrication is to be delivered to the plurality of lubricated regions of the vehicle. The controller device is further configured to provide control commands to cause the pump to deliver the lubricant to the plurality of lubricated regions according to the determined lubricant delivery frequency.

摘要： An autofill shutoff valve includes a valve body mounted to a lubricant reservoir and secured to a fill tube extending into the reservoir. The autofill shutoff valve has a valve stem extending through the valve body and into the lubricant reservoir. The valve stem is actuated by a plate disposed within the reservoir from a first position, wherein lubricant flows from a lubricant inlet to a lubricant outlet through the valve body, to a second position, wherein the valve stem blocks the flow of lubricant through the valve body. The autofill shutoff valve provides lubricant directly to the reservoir, thereby eliminating external plumbing and the autofill shutoff valve also prevents overfill of the reservoir by cutting off the flow when the reservoir is full.

摘要： A vent valve for an actuator disposed in a lubricant reservoir includes a bore extending through the plate, a seal disposed within the bore proximate a top surface of the plate, a retaining member extending about a lower opening of the bore, and a ball disposed within the bore between the seal and the retaining member. The vent valve is configured to allow air to pass from a lower portion of a lubricant reservoir as lubricant fills the lower portion. The vent valve also allows air to pass to the lower portion of the lubricant reservoir as lubricant is dispensed from the reservoir. The vent valve closes when the lubricant level reaches the vent valve, thereby preventing lubricant from flowing through the vent valve. The sealed vent valve allows the actuator to rise in response to a rising lubricant level.

摘要： A centerfill assembly for a lubricant reservoir includes a hollow tube for receiving lubricant from the top of the reservoir and loading the lubricant into the reservoir near the bottom of the reservoir. Loading the lubricant near the bottom of the reservoir introduces lubricant near where the stirring paddles mix the lubricant and near where the lubricant is loaded to the lubricant pump. Adding the lubricant near where the pumps load and near the stirring paddles helps to eliminate air pockets in the lubricant. In addition, having the centerfill rod minimizes exterior plumbing and allows for the mounting of valves on the fill line.

摘要： A protection mechanism for a lubricant reservoir is mounted within a valve protection chamber disposed on an actuator. The protection mechanism includes a valve actuating plate and an elastic member biasing the valve actuating plate upwards. The actuator is pushed upwards by a rising level of lubricant as the lubricant reservoir is filled. When the reservoir is full, the actuator causes the valve actuating plate to contact a valve stem. The valve actuating plate pushes the valve stem up to shut off a flow of lubricant to the reservoir through the shut off valve. During an overfill event the actuator shifts upward due to the rising level of the lubricant in the reservoir. As the actuator shifts upward, the elastic member compresses such that valve actuating plate remains static relative to the lubricant reservoir as actuator rises.
