Problems solved by technology
[0008] However, the shift joint of the prior art connects the shift lever 12 to the shift arm 11 through the pin shaft 13, and the pin shaft 13 must be worn to a certain extent after being used for a long time.
Therefore, the cooperation between the pin shaft 13 and the shift lever 12 or the shift arm 11 is more likely to loosen, which will cause the pin shaft 13 to fall off and cause the shift lever 12 to be disconnected from the shift arm 11.
[0009] In addition, since the connecting end of the shift arm 11 and the shift lever 12 has an opening 111, the strength of the shift arm 11 is relatively low. After a long period of use, the opening 111 of the shift arm 11 is prone to fatigue and lead to problems such as fracture. , similarly, it is easy to cause the problem that the shift lever 12 is disconnected from the shift arm 11

The invention provides a gear shifting joint, which comprises a gear shifting arm, a gear shifting rod, and a first connecting sleeve and a second connecting sleeve which are provided with inner bores, wherein the inner bore of the first connecting sleeve is intersected with the inner bore of the second connecting sleeve, and the intersection position between the first connecting sleeve and the second connecting sleeve is communicated; the gear shifting arm is arranged in the first connecting sleeve; the gear shifting rod is arranged in the second connecting sleeve in an oscillating way; a groove is formed on the circumferential surface of the gear shifting rod; and the gear shifting rod is clamped between the gear shifting arm and the inner side wall of the second connecting sleeve through the groove. Due to the adoption of the structure, the gear shifting joint provided by the invention can effectively improve the connection reliability between the gear shifting arm and the gear shifting rod.
Description
technical field [0001] The invention relates to the technical field of motor vehicle transmission, and more specifically relates to a shift joint. Background technique [0002] With the continuous improvement of my country's economic level, the field of motor vehicle technology has become relatively mature, and at the same time, it has driven the continuous innovation and development of the field of motor vehicle transmission technology. [0003] The shift joint, that is, the connecting part of the shift arm and the shift lever, plays an indispensable role in the field of motor vehicle transmission technology. [0004] One end of the shift lever is connected to the gear box of the motor vehicle, and the gear shift lever can drive the gear box to move, thereby realizing the speed change of the motor vehicle; the other end of the gear lever is connected to the gear shift arm to form a gear shift joint. The driver transmits the power to the shift lever by manipulating the shif...
