Embodiment 1

[0026] The gear position of the shift handle to be tested is as follows: image 3 As shown, the longitudinal gears are P gear, R gear, N gear, D gear and S gear from top to bottom, and the horizontal gears are + gear and - gear, wherein + gear and - gear can be switched mutually, and also You can switch between D file and + file, and between D file and - file. The gear position must be changed after the release button 10 must be pressed before the shift handle to be tested is switched every time, and the shift handle 1 can be fixed at the current gear after the release button 10 is released.

[0027] The automatic shifting test device of the universal shift handle is as follows: figure 2 As shown, it includes the shift handle 1 to be tested, the horizontal electric cylinder 2, the longitudinal electric cylinder 3, the electrical control system 11, the lateral force sensor 12, the longitudinal force sensor 13, the horizontal cylinder support 14, the longitudinal cylinder supp...

Abstract

The invention relates to an automatic unlocking mechanism for a universal type automatic gear-shifting testing device. The automatic unlocking mechanism for the universal type automatic gear-shifting testing device belongs to the fields of automotive technology, mechatronic engineering and robots, and is formed by a fastening piece, an electromagnet, a lever mechanism, a support, a spring, a handle and an unlocking button. The automatic unlocking mechanism provided by the invention can be used for properly completing unlocking and locking operation of a gear-shifting test, is compact and small in structure, and simple and reliable to control; has a force feedback function, can realize force-limited vibration test, and can effectively protect the testing device. The automatic unlocking mechanism provided by the invention is combined with the gear-shifting testing device, so that a full-automatic high-efficient operation process of gears can be realized, and a full-automatic gear-shifting test of a universal gear-shifting handle is completed.

Description

technical field [0001] The invention relates to an automatic unlocking device used in the automatic shift test of a universal shift handle, which belongs to the fields of automobile technology, mechanical and electronic engineering and robots. Background technique [0002] The shift handle is used to realize the gear position control of manual / automatic transmission. Its working principle is to rely on manpower to manipulate the shift handle to complete unlocking and gear shifting, and send electrical or mechanical signals to the gear shifting mechanism on the gearbox body. Thereby realizing the shifting operation process. The general-purpose shift handle generally has three control degrees of freedom: unlocking, lateral movement, and longitudinal movement. The unlock button is used to prevent misuse. The operator needs to press the unlock button before the shift operation can be performed, otherwise the shift handle is locked. , unable to shift gears. [0003] Fatigue tes...
