Bench for gearbox test

Abstract

The present invention discloses a bench for a gearbox test. The bench comprises a base on which two symmetrical T-shaped support frames are fixed. A support plate is pivotally connected between the T-shaped support frames and is used for supporting a gearbox to be tested. The base is also provided with an axial tilted device which is used for allowing the support plate and the gearbox arranged onthe support plate to carry out axial tilted movement around the axis of the support plate at the same time and fixing the support plate and the gearbox. The support plate is also provided with a radial tilted device which can be fixedly connected to the gearbox, and the radial tilted device is used for allowing the gearbox to carry out axial tilted movement around the axis of an input shaft and fixing the gearbox. The bench for a gearbox test has the advantages that the structure is simple and ingenious, the control is carried out through the radial tilting device and the axial tilting deviceand the posture of the gearbox can be simulated, various complicated working conditions can be simulated by using tilting angle parameters, the difficulty of the control is simplified, at the same time, the simulation precision is greatly improved, and the floor space requirement of equipment is reduced greatly.

Description

technical field [0001] The invention relates to a testing device for auto parts, in particular to a test stand for a gearbox, which belongs to the technical field of auto machinery and equipment. Background technique [0002] Automobile gearbox is a machine for mechanical power conversion. It is the core of the car. It has many internal components and complex structure. During the driving process of the car, as the road conditions change (uphill, downhill, turning, etc.), the posture of the gearbox will change. Changes, the flow of lubricating oil in the gearbox and the lubrication of each bearing position will also change. In order to simulate the situation of lubricating oil in different postures of the transmission, it is necessary for the test bench to be able to realize various road conditions, especially some extreme road conditions that cannot be realized by road tests. [0003] There are many defects in the existing transmission assembly tilt test bench. The inventi...

Problems solved by technology

[0004] Invention patent CN202994463U discloses a tiltable gearbox test system, the test system includes a test bench, the test bench includes a test device with a steering device and a hydraulic transmission mechanism at the bottom, one end is connected to the steering device and used to support The support of the test device, the base connected to the other end of the support, and the sensor control system connected to the hydraulic transmission mechanism and the test device respectively, but the structure of the system is complex, and the layout of the hydraulic oil supply pipeline, the sealing of the pipe fittings, and the solenoid valve need to be considered. The installation, etc., and the control angle is not precise enough

The disadvantage of this test system is that the control system is very complicated. When controlling the four lifting hydraulic cylinders at the same time, the cumulative error is large, and the transmission accuracy and assembly accuracy of the test system are very high.

[0006] German invention patent application DE102012220163A1 also proposes a tiltable gearbox test system, which uses a large arc track, and the gearbox can be tilted in one dimension on the large arc track, but it can be tilted according to the type. The transmission test system cannot achieve two-dimensional inclination. As the closest existing technology, it cannot be further improved on the basis of it.

[0007] It can be seen that the tiltable gearbox test system in the prior art is either complex in structure, difficult to control, or has substantial defects in function, and cannot simulate various complex gearbox working scenarios
