Hydraulic pump transmission mechanism of gearbox

Abstract

The invention provides a hydraulic pump transmission mechanism of a gearbox, and belongs to the technical field of gearbox hydraulic pumps. The hydraulic pump transmission mechanism of the gearbox aims to solve the problems that an existing hydraulic pump transmission mechanism cannot drive an air blowing structure to rotate through a transmission mechanism, so that air blowing operation cannot be carried out on a hydraulic pump shell which runs for a long time, and the practicability of the hydraulic pump transmission mechanism is reduced. The hydraulic pump transmission mechanism of the gearbox comprises a mounting plate, wherein the mounting plate is connected to the gearbox through bolts, and the rear end surface of the mounting plate is connected with a hydraulic pump main body through four fastening bolts; and the right side of the mounting plate is rotationally connected with a transmission mechanism, and the front end surface of the mounting plate is provided with an anti-loosening part at the front ends of the four fastening bolts. According to the hydraulic pump transmission mechanism of the gearbox, when a driving shaft rotates, air blowing fan blades at the rear end are driven to rotate through the transmission mechanism, so that external air is uniformly blown to a rear shell of the hydraulic pump main body through a flow guide mechanism, then the rear shell of the hydraulic pump main body can be effectively cooled, and the practicability of the hydraulic pump transmission mechanism is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of gearbox hydraulic pumps, and more specifically relates to a hydraulic pump transmission mechanism of a gearbox. Background technique [0002] The gearbox is a mechanism used to change the speed and torque from the engine. It can change the transmission ratio of the output shaft and the input shaft in fixed or stepwise steps, also known as the gearbox. Speed ​​changer is made up of speed change transmission mechanism and operating mechanism, and some automobiles also have power output mechanism. Most of the transmission mechanisms are driven by ordinary gears, and some are driven by planetary gears. Ordinary gear transmission transmission mechanisms generally use slip gears and synchronizers. [0003] For example, application number: CN201811439321.6 The present invention relates to a dual-clutch gearbox oil pump, including a casing and an end cover of the oil pump. The casing is provided with an oil inl...

Problems solved by technology

[0005] In order to solve the above technical problems, the present invention provides a hydraulic pump transmission mechanism of a gearbox to solve the problem that the existing hydraulic pump transmission mechanism has a single function and can only drive the hydraulic pump shaft to rotate, but cannot drive the blowing structure to rotate through the transmission mechanism, so that it cannot Blowing the casing of the hydraulic pump that has been running for a long time greatly reduces the practicability of the hydraulic pump transmission mechanism, and because the hydraulic pump transmission mechanism is located inside the gearbox, and the internal oil temperature of the gearbox will also increase when the gearbox is running for a long time , although the internal oil can be circulated through the hydraulic pump, the cooling effect is poor, thereby reducing the service life of the hydraulic pump transmission mechanism and the internal parts of the gearbox, and the existing hydraulic pump lacks effective anti-loosening between the mounting plate The structure makes the bolts connected between the hydraulic pump and the mounting plate easy to loosen due to the vibration generated during the operation of the hydraulic pump, thereby reducing the stability of the hydraulic pump during use
