Multifunctional flexible gearbox testing system

Abstract

The invention discloses a multifunctional flexible gearbox testing system, and solves a problem that a traditional testing system adopts a middle transition gearbox, the rotating inertia of a drivingsystem is increased, and the simulation is not facilitated; moreover, a front-engine front-wheel drive layout gearbox testing system for an automobile is mainly manually adjusted, the adjusting difficulty is large, and the coaxiality of 0.02 mm is difficult to achieve; meanwhile, a load motor can only achieve degree of freedom adjustment in two directions, the height direction is generally adjusted by adopting a cushion block mode, and adjustment is not convenient; and an efficiency test of the front-engine front-wheel drive layout gearbox testing system generally does not carry out oil temperature control, only the transmission efficiency at different rotating speeds is tested, and the oil temperature has a certain influence on transmission efficiency of a transmission gear. The multifunctional flexible gearbox testing system comprises a driving motor, a loading moto I, a loading motor II, a front-engine front-wheel drive layout gearbox and a detection system, wherein a driving motormounting platform is arranged at the bottom of the driving motor; and a testing machine mounting platform is arranged at the bottom of the loading motor I and the loading motor II.

Description

technical field [0001] The invention relates to a gearbox testing system, in particular to a multifunctional and flexible gearbox testing system. Background technique [0002] The traditional automotive front-wheel-drive gearbox test system consists of a drive motor and two load motors. Generally, an intermediate transition gearbox or a transition timing belt is added to the input shaft of the tested gearbox to increase the input of the tested gearbox. The center distance between the shaft and the output shaft is to facilitate the use of a drive motor with a large center distance. The synchronous belt is used. Due to the limitation of the synchronous belt, the general input speed cannot exceed 8000rpm; the intermediate transition gearbox is used, although 20000rpm can be achieved. High input speed, but increases the moment of inertia of the drive system, which is not conducive to simulating the engine or on-board motor. [0003] At the same time, the test system of the fron...

Problems solved by technology

[0009] The purpose of the present invention is to provide a multifunctional and flexible gearbox testing system, which can solve the problem that the traditional testing system uses an intermediate transition gearbox. Although a high input speed of 20,000rpm can be achieved, the moment of inertia of the drive system is increased, which is not necessary. It is good for simulating the engine or on-board motor; and the test system of the front-wheel-drive gearbox of the car is mainly adjusted manually, which is difficult to adjust, and it is difficult to achieve a coaxiality of 0.02mm; at the same time, the load motor can only be adjusted in two directions of freedom, and the height The direction is generally adjusted by pads, which is inconvenient to adjust; moreover, the efficiency test of the front-wheel-drive gearbox test system generally does not control the oil temperature, but only tests the transmission efficiency at different speeds, but the oil temperature has an impact on the transmission efficiency of the transmission gear. It has a certain influence; at the same time, when the automotive front-wheel-drive gearbox test system performs a differential test on the tested gearbox, it generally controls the speed of the drive motor, and gradually adjusts the torque of the two load motors to realize the tested gearbox. Check the different speeds on both sides, but this adjustment method is difficult to adjust, takes a long time to adjust, and is unstable
