Embodiment 1
[0020] Figure 1~ image 3 As shown, the device includes: an overall lifting mechanism A, an automatic gear selection mechanism B and an automatic gear shifting mechanism C, wherein: the automatic gear selection mechanism B and the automatic gear shifting mechanism C are arranged on the overall lifting mechanism A, when the transmission moves along the transmission When the feeding channel enters, the lifting mechanism A rises as a whole, which avoids interference.
[0021] The overall lifting mechanism A is specifically connected in rotation with the automatic gear selection mechanism B through the connecting component D, and the automatic gear selection mechanism B and the automatic gear shift mechanism C are movably connected.
[0022] Such as Figure 1a and Figure 1b As shown, the overall lifting mechanism A includes: an integral base 20, a lateral movement guide rail assembly 21, a lateral movement standard cylinder 22, a longitudinal movement standard oil cylinder 23, a...

A transmission automatic gear selecting and shifting mechanism for an automatic transmission calibration table comprises an integral lifting mechanism, an automatic gear selecting mechanism and an automatic gear shifting mechanism. The automatic gear selecting mechanism and the automatic gear shifting mechanism are connected with the integral lifting mechanism to achieve synchronous motion during feeding and discharging so as to avoid interference, the integral lifting mechanism is in rotating connection with the automatic gear selecting mechanism through a connection assembly, and the automatic gear selecting mechanism and the automatic gear shifting mechanism are in movable connection. The complex gear shifting actions completed through the operation of an electronic control hydraulic valve in the prior art are changed into rotating motion with a certain angle around the center of a gear shifting arm. The structure comprises gear selecting parts and gear shifting parts, and the effect of different gear selecting forces is overcome. The transmission automatically selecting and shifting mechanism is clear in gear shifting position, appropriate in gear shifting force and gear selecting force and convenient to manually control so as to solve the problem caused by gear selecting and shifting operation and control of the calibration table.
Description
technical field [0001] The invention relates to a device in the technical field of automobile transmissions, in particular to a transmission automatic selection and shifting mechanism used in an automatic transmission inspection platform. Background technique [0002] The existing transmission loading test bench can be used to test some basic performances of the automobile transmission assembly, such as gear noise detection, speed ratio detection, etc. However, it is difficult to realize the function of manual shifting for a transmission that is shifted through an automatic shifting system, and it is impossible to detect various signals of the various states of the calibration table during the calibration, including neutral gear recognition, and the end of calibration. detection. Therefore, at the present stage, there is an urgent need for a vehicle transmission test stand with an innovative gear selection mechanism, which can meet the requirements of using the existing gea...
