Problems solved by technology

[0003] However, in some applications, the direction of the output shaft of the motor will change. For example, when the electric vehicle is moving forward, its main motor rotates forward, and when the electric vehicle reverses, its main motor rotates in the reverse direction. In this case, it is often necessary to set two The main motor rotates forward to drive one of the oil pumps to pump oil, and the main motor rotates in reverse to drive the other oil pump to pump oil. The structure of the oil circuit is relatively complicated, which increases the cost of the hydraulic system and increases the cost of the hydraulic system. The overall weight of the hydraulic system, while also increasing the footprint of the hydraulic system

Abstract

The invention relates to the technical field of power equipment, in particular to a bidirectional gear oil pump. The technical problem that a driving shaft of an existing oil pump can only pump oil inone direction is solved. An oil pump shell inner cavity of the oil pump is divided into a front work cavity and a rear work cavity, two parallel driving shafts are arranged on an oil pump shell, andan oil pump gear and an intermediate gear are mounted on each driving shaft. The oil pump gears are arranged in the front work cavity, and the intermediate gears are arranged in the rear work cavity.The work directions of the two oil pump gears are opposite, and the driving shaft and the first oil pump gear are locked clockwise in one direction. The second oil pump gear and one of the two intermediate gears are locked with the driving shaft where the second oil pump gear and one of the two intermediate gears anticlockwise in one direction. The other two gears and the driving shaft where the two gears are located are locked anticlockwise. The two intermediate gears are connected through a transmission component, and therefore the driving shaft and the driven shaft can synchronously rotateanticlockwise. The oil pump is suitable for electric cars and other occasions where driving motors need to rotate in two directions.

Description

technical field [0001] The invention relates to power equipment technology, in particular to a bidirectional gear oil pump technology. Background technique [0002] The traditional oil pump is mainly composed of the pump casing, the pump drive shaft and the oil pump gear. The oil outlet and inlet of the oil pump are fixed, and the oil pump rotation direction of the oil pump gear is also fixed. When working, the motor drives the pump to drive the shaft to rotate to realize oil pumping. [0003] However, in some applications, the direction of the output shaft of the motor will change. For example, when the electric vehicle is moving forward, its main motor rotates forward, and when the electric vehicle reverses, its main motor rotates in the reverse direction. In this case, it is often necessary to set two The main motor rotates forward to drive one of the oil pumps to pump oil, and the main motor rotates in reverse to drive the other oil pump to pump oil. The structure of th...
