Embodiment 1

[0078] Such as figure 1 As shown, this embodiment provides a powertrain lubricating device, including an oil pan 1, two filter collectors 2 installed in the oil pan 1, a valve for controlling the on-off of the filter collector 2, and a valve for driving the collector The filter absorbs the power unit 3 of lubricating oil in the oil pan 1 , the oil filter 4 used to filter the lubricating oil before entering the powertrain, and several oil pipelines 5 .

[0079] Among them, the two filter collectors include near the rear ( figure 1 Shown by the arrow A in the middle), the first set filter 21 set, and near the front of the car ( figure 1 The second filter collector 22 is set as indicated by the middle arrow B), and the valves include a first valve 21a for controlling the opening and closing of the first filter collecting filter 21 and a second valve 22a for controlling the opening and closing of the second filter collecting filter 22 .

[0080] Since there are two filter col...

Embodiment 2

[0088] This embodiment provides a method for lubricating the powertrain of a vehicle using the lubricating device described in Embodiment 1, including:

[0089] Judging step, judging the tilt state of the liquid surface in the oil pan 1;

[0090] Execute the step of selecting and opening at least one collector filter whose liquid suction port is below the liquid level according to the tilt state of the liquid level.

[0091] Judging the inclination state of the liquid surface in the oil pan 1 through the judging step, and then selecting and opening at least one filter with a suction port below the liquid surface according to the inclination state of the liquid surface through the execution steps, so as to ensure various conditions of vehicle operation Under, for example, braking / deceleration, starting / accelerating, constant speed / stationary, uphill, downhill and flat road, the suction port of at least one filter 2 can always be located below the liquid level in the oil pan 1, ...

Embodiment 3

Abstract

The invention provides a power assembly lubricating device. Two or more than two suction filters are provided, so that during specific use, different suction filters can be started up as required to ensure that under various running conditions of a car, such as braking/speed reducing, starting/accelerating, running at uniform speed/keeping still and going uphill/downhill/on flat roads, the suction opening of at least one suction filter is always below the liquid level in an oil pan, accordingly, during design of the oil pan, the demand on the depth of the oil pan is lowered, a relatively large ground clearance is guaranteed for the car, and the car passing ability is improved. Meanwhile, the two suction filters are controlled to be started in a switching manner under the different running conditions of the car to ensure that the suction filters can always suck a lubricant in the oil pan, and accordingly, the power assembly of the car is guaranteed to be always well lubricated.

Description

technical field [0001] The invention relates to a power assembly lubricating device, a lubricating method and a lubricating system using the lubricating device, and belongs to the technical field of vehicle lubricating. Background technique [0002] There are a large number of kinematic pairs among the moving parts inside the automobile engine. The relative motion between these kinematic pairs is very violent, and the vehicle lubrication device is required to deliver lubricating oil to each kinematic pair, so that each kinematic pair can have enough oil for lubrication and cool down. [0003] Existing cars generally adopt the form of four-wheel drive. The so-called four-wheel drive means that the front and rear wheels of the car have power, and the output torque of the engine can be distributed in different proportions on all the front and rear wheels according to the state of the driving road surface, so as to improve the driving performance of the car. driving ability.
