Description

[Detailed Description of the Invention] Industrial Application Field The present invention can be used, for example, in transmission test equipment installed in automobile manufacturing factories to perform performance tests on transmissions before they are assembled into a vehicle body. The present invention relates to an inter-shaft interlocking device for a transmission test facility that interlocks the input shaft of a transmission and the output end rotating shaft of a drive device.

Conventional technology When performing interlocking between axes, if the transmissions are of the same model (for the same vehicle model), spline fitting between both axles can be performed without any problems, but when different models are supplied, the input Spline fitting cannot be performed smoothly and reliably because the diameters of the shafts are different. Therefore, in the past, for example,
As seen in Publication No. 178345, the output end rotating shaft is provided with a clamp device that acts on the input shaft from the outside, and relay shafts are rotatably arranged at multiple locations above and below a bearing device that can be raised and lowered. configurations are provided.

Problems to be Solved by the Invention According to the above-mentioned clamp type, the clamp claw fits into the spline valley of the input shaft, and rotation is transmitted through the clamp claw.
Damage to the spline portion often occurs. Furthermore, in the case of a type of bearing device that can be raised and lowered, the bearing device is vertically long and the uppermost relay shaft tends to swing, so spline fitting of the uppermost relay shaft cannot be performed quickly and smoothly.

The purpose of this invention is to develop a transmission test facility that is compatible with multiple types of transmissions, can be linked quickly and reliably, and can simplify the structure and reduce space. The object of the present invention is to provide an inter-axle interlocking device.

Means for Solving the Problems In order to achieve the above object, the inter-shaft interlocking device of the transmission test equipment in the present invention is an inter-shaft interlocking device between the input shaft of the transmission and the output end rotating shaft of the drive device. At the same time, a movable table is provided that is movable in a lateral direction perpendicular to the opposing direction of both axes, and a moving device that interlocks with this movable table is provided.
Bearing devices movable separately in opposing directions are provided at multiple locations on the movable base in the moving direction, and these bearing devices have one end that can be freely interlocked with the input shaft and the other end that can be freely interlocked with the output end rotating shaft. Each relay shaft is rotatably provided.

Effects According to the configuration of the present invention, one end of the relay shaft is interlocked with the input shaft and the other end is interlocked with the output end rotating shaft, with the transmission fixed at a predetermined position. can be linked with the output end rotating shaft. At this time, since the bearing device moves in the opposite direction, the interlocking of the relay shaft with the input shaft can be performed smoothly and reliably, and by moving the movable base according to the supplied transmission model, this can be done smoothly. A suitable relay shaft for the transmission can be selected and positioned between the input shaft and the output end rotation shaft.
