Embodiment Construction

[0040] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific implementation manners described here are only used to explain the present invention, rather than to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.

[0041] Some orientation words are defined in the present invention, under the situation of not making contrary explanation, used orientation words such as " upper ", " lower ", " left ", " right " mean that the speed changer testing device provided by the present invention is in the normal state. Defined in the context of usage, "inside" and "outside" refer to the inside and outside relative to the contour of each part itself. These orientation words are adopted for easy understanding, and thus do n...

Abstract

The invention relates to the technical field of speed changer testing, and discloses a speed changer testing device. The speed changer testing device comprises a first locking assembly, a second locking assembly, a force application assembly and an angle gauge, wherein the first locking assembly can lock a first output end of a speed changer, the second locking assembly can lock a second output end of a speed changer assembly, the force application assembly is connected with the input end of the speed changer, and the angle gauge is used for measuring the rotation angle of the force application assembly. When the speed changer assembly is put into a gear, an operator applies force to the force application assembly, the force application assembly drives the input end of the speed changer assembly to rotate until the force application assembly reaches preset torque, the angle gauge measures the rotation angle of the input end of the speed changer assembly in the rotation process, and calculates the meshing situation of gears of a transmission system in the speed changer assembly at the gear according to the rotation angle of the input end of the speed changer assembly, a gear assembly does not need to be disassembled, operation is convenient, and the testing efficiency and accuracy are improved.

Description

technical field [0001] The invention relates to the technical field of transmission testing, in particular to a transmission testing device. Background technique [0002] The transmission is mainly used in vehicles and other mechanical equipment. Through the meshing of gears with different transmission ratios, the driving speed of the vehicle and the torque on the driving wheels can be changed in a wide range. [0003] In order to give full play to the best running performance of the transmission, improve the power of the car and the NVH (Noise Vibration Harshness, noise, vibration, harshness) performance of the vehicle, reduce the shock and frustration of shifting, and increase the ride comfort and ride comfort, It is necessary to test the gear mesh clearance and gear mesh stiffness of the internal transmission system of the transmission. [0004] In the prior art, the gear meshing clearance in the transmission is generally tested by using the lead pressing method, the rul...
