Embodiment Construction

[0027] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0028] like figure 1 , figure 2 until Figure 18 As shown, the Oldham coupling used for driving test of automobile rear axle or final drive assembly, including the first half coupling 3, the second half coupling 6 and the middle Oldham between them 4. The first half-coupling 3 , the middle Oldham 4 and the second half-coupling 6 all have central holes, and the central holes on the first half-coupling 3 are used for plug-in connection driving The drive shaft 1 of the device, the first half-coupling 3 is inserted into the center hole of the second half-coupling 6 after passing through the center hole of the middle Oldham slider 4, and the center hole of the second half-coupling 6 The inner diameter is larger than the outer diameter of one end of the first half coupling 3 inserted therein for compensating the coaxiality error between the drive...

Abstract

The invention relates to a double slider coupling for drive test of an automobile rear axle or final drive assembly. The double slider coupling comprises a first half coupling, a second half coupling and a middle double slider between the first half coupling and the second half coupling; the first half coupling, the middle double slider and the second half coupling are all provided with a centre hole; a drive shaft connected with a drive device is inserted into the centre hole of the first half coupling; the first half coupling passes through the centre hole of the middle double slider and then is inserted into the centre hole of the second half coupling; and the inner diameter of the centre hole of the second half coupling is greater than the outer diameter of the end of the first half coupling inserted into the centre hole of the second half coupling so as to compensate for the coaxiality error between the drive shaft and the final drive flange. The double slider coupling has the advantages that: as the double slider coupling can be connected to the drive shaft in a single-shaft supporting way, automatic butt joint between the drive shaft and the flange can be realized; and the working efficiency is improved considerably.

Description

technical field [0001] The invention belongs to the technical field of shaft couplings, in particular to an Oldham coupling used for driving tests of automobile rear axles or final reducers. Background technique [0002] The traditional Oldham coupling is mainly used for the connection between the output shaft of the reduction mechanism and the actuator to realize the transmission of mechanical energy. Usually, the mechanisms at both ends of the Oldham coupling are fixed and supported by two shafts. In the automobile industry, the vibration and noise generated during the operation of the automobile are one of the most important indicators for evaluating the performance of the automobile, and it also directly affects the comfort of the ride and the safety of driving. The transmission system of the automobile is the most important source of vibration and noise. As a key component of the transmission system, the main reducer assembly of the automobile directly affects the driv...
