Problems solved by technology
[0003] When the transmission device is shut down, the oil in the pressure oil tank 3 cannot flow to the oil pan 1, so that the oil volume and oil level of the oil pan 1 after each shutdown are uncertain, and cannot be measured through the oil pan 1 The height of the oil level measured by the oil dipstick can accurately judge whether the oil volume in the entire transmission device is within the normal working range, which is not conducive to the work and maintenance of the transmission device
In addition, in the existing hydromechanical comprehensive transmission device of tank armored vehicles, a slide valve is used to simultaneously realize the pressure adjustment of two substances with greatly different viscosities, oil and gas, and the pressure fluctuation range is large.

Embodiment Construction
[0019] In order to make the purpose, content and advantages of the present invention clearer, the specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0020] Such as figure 2 As shown, the multifunctional pressure oil tank adjustment device provided by the present invention includes an oil pan 1, an oil return pump 2, a pressure oil tank 3 and an oil supply system 7, and the oil return pump 2 draws back the oil in the transmission oil pan 1 Into the pressure oil tank 3, the pressure oil tank 3 supplies oil for each component through the oil supply system 7. The device also includes a constant pressure balance valve 4, an air pressure valve 5, an air supply valve 6 and a transmission device pressure control oil circuit 8. The working state of the pressure oil tank 3 is regulated by the joint action of the constant pressure balance valve 4 , the air pressure valve 5 an...

The invention belongs to the technical field of mechanical transmission and provides a multifunctional pressure oil tank adjusting device to accurately judge whether the oil amount in the whole transmission device is in a normal work range or not. By arranging a constant pressure balance valve, an air pressure valve and a gulp valve, a pressure oil tank normally works when the transmission device works, and after the transmission device stops, the oil-level height in the pressure oil tank and the oil-level height of an oil sump are quickly balanced and consistent, so that whether the oil amount in the whole transmission device is in the normal work range or not can be accurately judged through the oil-level height measured by a dip stick of the oil sump; the air pressure valve is small in size and the mounting position is flexible; oil pumped back to the pressure oil tank by an oil scavenger pump contains much air, and the gulp valve can supplement air to the pressure oil tank, so the normal work of the pressure oil tank is ensured, an air pump in the conventional scheme is eliminated and the design of the transmission device is more facilitated.
Description
technical field [0001] The technical field of mechanical transmission of the present invention, in particular relates to a multifunctional pressure oil tank regulating device. Background technique [0002] In the existing tank and armored vehicle hydromechanical integrated transmission device, the adjustment of the pressure oil tank is realized by the air pump and the constant pressure valve. Such as figure 1 As shown, the oil return pump 2 pumps the oil in the transmission oil pan 1 back into the pressure oil tank 3, and the pressure oil tank 3 supplies oil 6 for the work of each component. The working state of the pressure oil tank 3 is determined by the air pump 5 and the constant pressure valve 4 Adjustment, the air pump 5 supplies air into the pressure oil tank 3, the inlet of the constant pressure valve 4 is set at a certain height of the pressure oil tank 3 to determine the oil-gas ratio in the pressure oil tank 3, the opening pressure of the constant pressure valve ...
