Oil mass is larger, and corresponding churning loss just will increase, so that gearbox transmission efficiency declines；When the depth of gear immersed in liquid level is small
When, the lubricants capacity that gear rotation takes up is smaller, and corresponding churning loss can also reduce, so that gearbox transmission efficiency is higher.
Gear-box lubricating oil liquid level should be depending on the demand for lubricating oil amount of significant points under gearbox specific operation.
Since automobile gearbox often has multiple gears, and the working range of each gear is wider.Therefore, become under different operating conditions
Fast case is to the difference of flow of lubrication requirement needed for meeting operating condition, and difference is very big.But it is initial due to gearbox
Oil mass is determining, therefore can only determine lubricating oil liquid level height according to the demand for lubricating oil amount under bad working environments, to guarantee to become
Fast case can work normally under any operating condition.But determining oil level height is opposite with other general works in this case
It is relatively high for condition, while the churning loss also resulted under Part load inevitably increases.With garage
The continuous development of industry, requirement of the society to energy utilization rate are continuously improved, and requirement of the market to vehicle transmission efficiency also constantly mentions
It is high.

Breath, then judges the instantaneous operating conditions of gearbox, and the gearbox that comprehensive vehicle status sensor detects is crucial
The real time temperature information of lubricant housings obtains a target lube supply amount desired value, and then obtains corresponding transmission housing
The interior target oil level height value of body (11), comparison vehicle status sensor real-time detection to oil level height value make raising profit
The decision of lubricating oil liquid level, controller control driving motor (31) rotate forward, and drive the synchronous forward rotation of screw rod (32),
And then floating chamber (21) is driven to move downward in cavity (17), increase the volume of floating chamber (21) dip lubrication oil level, lubrication
Oily (41) liquid level rises, until until rising to the target oil level height value for meeting and setting, move downward when floating chamber (21) and
Be completely immersed in lubricating oil (41) it is internal when, the oil level height of the lubricating oil (41) in gear box casing (11) reaches maximum at this time
Value, the regulator control system reach the gearbox lubrication oil mass maximum value that can be supplied.
The regulation method for reducing lubricating oil liquid level height is as follows:
In the regulator control system, the controller in control assembly receives the vehicle-state letter that vehicle status sensor detects first
Breath, then judges the instantaneous operating conditions of gearbox, and the gearbox that comprehensive vehicle status sensor detects is crucial
The real time temperature information of lubricant housings obtains a target lube supply amount desired value, and then obtains corresponding transmission housing
The interior target oil level height value of body (11), comparison vehicle status sensor real-time detection to oil level height value make reduction profit
The decision of lubricating oil liquid level, controller control driving motor (31) rotate backward, and drive the synchronous backward rotation of screw rod (32),
And then floating chamber (21) is driven to move upwards in cavity (17), reduce the volume of floating chamber (21) dip lubrication oil level, lubrication
Oily (41) liquid level decline, until until dropping to the target oil level height value for meeting and setting, move upwards when floating chamber (21) and
When being completely exposed lubricating oil (41) liquid level, the oil level height of the lubricating oil (41) in gear box casing (11) reaches minimum at this time
Value, the regulator control system reach the gearbox lubrication oil mass minimum value that can be supplied.
