Problems solved by technology

In order to make it have the function of shifting back to the center, that is, when the transmission returns to neutral from the first, second or fifth reverse gears, the shift handle automatically returns to the middle position of the shifter, and the shift levers on both sides of the shift lever are often used. The structure with two springs on the gear shaft relies on the force of the two springs to make it return to the center. This kind of structure is more complicated and uses more parts, which has the disadvantages of taking up a lot of space and high cost.

Embodiment Construction

[0012] Below in conjunction with accompanying drawing, the present invention will be further described:

[0013] see figure 1 , figure 2 A transmission shift box mechanism with a single return spring is shown, including a gear selection mechanism, a gear shift mechanism, and a five-reverse gear interlocking mechanism.

[0014] see image 3 , the improvement point of the present invention lies in the gear selection mechanism, which includes a gear shift box 1, a gear shift shaft 9, a shift lever 6, a shift support block 5, a return spring 4, a gear shift shaft washer 3 and a collar 2, etc. . The gear selection rocker arm 11 is fixed on the outside of the gear shift case 1 casing by screws and cooperates with the gear shift rocker arm. The shift shaft 9 is connected in series in the shift case 1, and is supported by the two ends of the shift case. The shift rocker arm 12 and the shift lever 6 are connected on the shift shaft 9 by pins, and the collar 2 is stuck in the groo...

Abstract

The invention discloses a gear shifting box mechanism of a transmission with a single return spring. The gear shifting box mechanism comprises a gear selecting mechanism, a gear shifting mechanism and a five-gear-reversing interlocking mechanism. The gear shifting box mechanism is characterized in that the gear shifting mechanism is a gear withdrawal return device with a single spring. The gear shifting box mechanism has the advantages that the structure is simplified, cost is saved, and a gear shifting performance is improved.

Description

technical field [0001] The invention relates to a shift box mechanism of an automobile transmission, in particular to a shift box mechanism of a microcar transmission with five forward gears and a single return spring. technical background [0002] At present, the transmission basically uses an independent shift box to realize the shifting and selecting functions. In order to make it have the function of shifting back to the center, that is, when the transmission returns to neutral from the first, second or fifth reverse gears, the shift handle will automatically return to the middle position of the shifter. The structure with two springs on the gear shaft relies on the force of the two springs to make it return to the center. This structure is more complicated, uses more parts, and has the disadvantages of taking up a lot of space and high cost. Contents of the invention [0003] The object of the present invention is to provide a transmission gear selection mechanism wi...
