The shape and position detection system of the selector and shift ball head of the transmission selector and shift mechanism and the shift finger

Abstract

The invention discloses a position detection system for the gear selection and shift balls and the gear shift finger of a transmission shift mechanism. The position detection system is characterized in that it comprises a base, the base is provided with a mounting bracket for fixedly installing a shift mechanism to be detected, a gear selection ball detection mechanism for detecting the position of a gear selection ball, a gear shift ball detection mechanism for detecting the position of a gear shift ball, and a gear shift finger detection mechanism for detecting the position of a gear shift finger. The position detection system is able to quickly detect the position sizes of the gear selection and shift balls and the gear shift finger of a transmission shift mechanism, unified in detection standard, beneficial to improvement of the quality of outgoing products, fast in detection speed and high in efficiency.

Description

technical field [0001] The invention relates to the technical field of automobile testing, in particular to a shape and position detection system of a gear selector ball head and a shift finger of a transmission selector shift mechanism. Background technique [0002] The gear selection mechanism of the transmission is an important part of the automobile transmission. It is one of the most important parts inside the transmission. The gear selection of the gear shifter transmits the force and torque to the gear selection mechanism through the flexible shaft. With its own structural characteristics, the force and torque transmitted by the shift flexible shaft are reflected on the shift finger, and the shift finger rotates and moves to transmit the torque to the shift shaft, which drives the shift fork and then acts on the synchronizer. Due to the frequent switching of gears in a timely manner during the driving of the car, if the gear shift mechanism of the transmission cannot ...

AI Technical Summary

Problems solved by technology

Due to the frequent switching of gears in a timely manner during the driving of the car, if the gear shift mechanism of the transmission cannot move the shift fork to the corresponding position, that is, the synchronizer cannot be moved to the corresponding position, it will not be possible to shift gears smoothly. It may even damage the synchronizer due to the speed difference and torque difference between the synchronous ring gear and the sleeve of the synchronizer, and then damage the transmission, which will cause serious safety hazards in driving the car. Select the key shape and size of the shift mechanism for test evaluation

[0003] The existing production process is mainly to check the shape and size of the shift ball head and the shift finger of the shift mechanism by the workers using the inspection tool. Due to the differences in the detection skills and subjective judgment ability of the workers, the detection After the product quality is uneven

Moreover, in the above detection process, the selector shift ball and shift finger are usually detected separately, which cannot be judged comprehensively, and the detection speed is slow and the efficiency is low.
