Embodiment Construction

[0017] like figure 1 , figure 2 and image 3 As shown, this embodiment is composed of a first lifting rod 1 and a second lifting rod 2, a second lifting rod 2 extends from the upper part of the first lifting rod 1, and the first lifting rod 1 and the second lifting rod 2 are coaxial; The center of the first lifting rod 1 has a first hole 11, the center of the second lifting rod 2 has a second hole 21, the first hole 11 and the second hole 21 are connected, and the diameter of the second hole 21 is smaller than that of the first hole 11, the first hole The lower section in 11 is provided with a rubber sleeve 13;

[0018] Two corresponding threaded holes 12 are provided on both sides of the first lift rod 1, and the second lift rod 2 is provided with a through hole 22. The threaded holes 12 are used to fasten the connection with the gear shift lift rod of the gearbox. The hole 22 is used for inserting the pull rod, which is used for lifting the transmission shift rod.

Abstract

The invention relates to a conversion device for a shift quality test of an automatic transmission vehicle. The conversion device is composed of a first raising rod and a second raising rod, wherein the upper part of the first raising rod is extended with the second raising rod, and the first raising rod and the second raising rod are coaxial; a first hole is formed in the center of the first raising rod, a second hole is formed in the center of the second raising rod, and the first hole communicates with the second hole; the diameter of the second hole is smaller than that of the first hole,and a rubber sleeve is arranged at the lower segment in the first hole; two corresponding threaded holes are formed in the two sides of the first raising rod, and a through hole is formed in the second raising rod; the threaded holes are used for fastening the connection with a gearbox shift raising rod, and the through hole is used for inserting a pull rod and raising the gearbox shift raising rod. The conversion device can meet the vehicle test requirements that the raising rod needs to raise to unlock P catch. The range of application of shift quality measuring equipment is expanded, and meanwhile the tooling manufacturing cost is also saved.

Description

technical field [0001] The invention relates to a conversion device for shifting quality testing of automatic transmission vehicles. Background technique [0002] At present, the commonly used ways to unlock the P gear of the shifter in the market are divided into two types: the push-down type and the lift-up type. Because the lift-up type shifter needs to lift the lift rod to unlock the P gear, and the test equipment ball sensor needs Depressing is required to secure the shifter lifter, so the test equipment cannot perform vehicle testing of shifters that require lifter lifter P to unlock. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to solve the problem that the existing test equipment cannot carry out the vehicle test of the shifter that needs to be lifted up to unlock the P-block, and to provide a conversion device for the shift quality test of an automatic transmission vehicle. [0004] The present invention is composed of a first lifting...
