Problems solved by technology
Due to the large number of gears and the small distance between adjacent gear selection slots, how to accurately and quickly select and shift gears has always been a difficult problem for drivers, especially for drivers who are not familiar with this type of gearbox. It is more difficult, and there are often situations where the wrong position is selected or the position is not selected
Especially when it comes to sub-gearbox high / low gear switching, it is often difficult to shift gears or even fail to shift gears

The invention relates to an independent hydraulic oil source for a vehicle, which provides hydraulic power for an automatic shifting mechanism of the vehicle. The oil source can ensure that the hydraulic oil is not polluted, reduce the pollution of the hydraulic oil in an oil cylinder of an automatic gear shifting operation mechanism to intensify abrasion and prolong the service life of the automatic gear shifting operation mechanism. A vehicle-mounted 24V direct current storage battery is used for supplying power for the oil source, and stable and reliable pressure oil is supplied for an automatic gear shifting operation system. The independent hydraulic oil source is provided with a pressure and temperature sensor (12) which can transmit signals to a computer gear shifting controller so as to control the pressure range of the system. The pressure and temperature sensor (12) continuously detects the pressure of the oil source. When the pressure is less than the minimum value required by the system, a direct current motor (1) is started to pump oil and apply pressure for the oil source, and when the pressure reaches the maximum pressure required by the system, the direct current motor (1) stops working, therefore, the pressure of the oil source is ensured to be in a pressure range required by the system, and stable oil pressure is supplied for the automatic gear shifting operation system.
Description
technical field [0001] The invention relates to an independent hydraulic oil source which provides hydraulic power for an automatic gear shifting mechanism of a vehicle. The device is used on a mechanical automatic transmission (Automated Mechanical Transmission) to realize automatic shifting operation. Background technique [0002] Multi-speed gearboxes (generally more than 8 gears) are generally composed of main and auxiliary gearboxes. During the driving process of the vehicle, the driver must frequently perform operations of selecting positions and shifting gears to meet his needs for engine power. Due to the large number of gears and the small distance between adjacent gear selection slots, how to accurately and quickly select and shift gears has always been a difficult problem for drivers, especially for drivers who are not familiar with this type of gearbox. It is more difficult, and there are often situations where the wrong position is selected or the position is ...
