Embodiment 1

[0043] like figure 1 As shown, in the transmission gear arrangement diagram referred to in the present invention, the N gear is a neutral gear, and the selection from the neutral gear to the fifth reverse gear referred to in the present invention corresponds to moving from the N position to the middle of 5-R in the figure position; the five reverse gear positions referred to in this patent also refer to the position in the middle of 5-R in the figure.

[0044] like Figure 2-6As shown, the present embodiment provides a five-reverse gear interlocking mechanism of an automobile transmission, including an interlocking plate assembly 1, a pin 2, a selector shift shaft assembly 3, a reverse gear lock cam assembly 4, and a control pawl 5. The interlocking The plate assembly 1 and the control pawl 5 are assembled on the gear selection shaft assembly 3 through the pin 2, and when the interlocking plate assembly 1 is assembled on the transmission, it cannot rotate with the rotation of...

Embodiment 2

[0056] An automobile, comprising the five-reverse-gear interlocking mechanism of the automobile transmission described in Embodiment 1.

[0057] The five-reverse gear interlocking mechanism of the automobile transmission utilizes the leverage of the parts, through the interaction between the control claw 5 and the reverse gear lock cam assembly 4, and realizes the mechanical interlock function of the fifth gear and the reverse gear with the least parts (locked in) After the fifth gear, you cannot directly shift from the fifth gear to the reverse gear, you need to go back to the neutral gear before you can shift to the reverse gear, but you can directly shift to the fifth gear after shifting into the reverse gear), the interlocking performance is firm and reliable, and the control claw 5 is also Functions such as gearshift block, neutral switch induction, spring steel ball limit, etc., all functions are realized with the least parts and the simplest structure, the structure is s...

Abstract

The invention relates to a gear shifting mechanism of an automobile transmission, in particular to a five gear and reverse gear interlocking mechanism of the automotive transmission. The five gear andreverse gear interlocking mechanism comprises an interlocking plate assembly, a pin, a gear selecting and shifting shaft assembly, a reverse gear lock cam assembly and a control claw, the interlocking plate assembly and the control claw are mounted on the gear selecting and shifting shaft assembly through pins, the interlocking plate assembly is also mounted on an automobile transmission shell, and the interlocking plate assembly does not rotate along with rotation of the gear selecting and shifting shaft assembly, but the interlocking plate assembly moves along with axial movement of the gear selecting and shifting shaft assembly, and the control claw moves together with the gear selecting and shifting shaft assembly synchronously; and the reverse gear lock cam assembly is mounted on theautomobile transmission shell. By means of the five gear and reverse gear interlocking mechanism, the interlock functions that direct engagement into a reverse gear cannot be achieved after the fifthgear is engaged and the fifth gear can be engaged after the reverse gear is engaged are achieved, and the five gear and reverse gear interlocking mechanism is simple in structure, high in interlocking precision, firm and reliable, small in occupied space and low in cost.

Description

technical field [0001] The invention relates to a shifting mechanism of an automobile transmission, in particular to a five-reverse gear interlocking mechanism of an automobile transmission. Background technique [0002] Currently on the market, the fifth gear and the reverse gear are arranged on the same side of the car transmission. In order to avoid the driver's misoperation directly from the fifth gear (high speed gear) to the reverse gear, it is necessary to set the fifth gear and the reverse gear on the transmission. The lock device allows the transmission to be directly linked to the fifth gear from the reverse gear, but does not allow the transmission to be directly linked to the reverse gear from the fifth gear. [0003] The five-speed and reverse-gear interlock mechanisms on the market are relatively complex in structure, with many components and high cost, and the reverse-gear lock cam assembly is installed on the shift shaft, which takes up a lot of space. There...
