Embodiment 1

[0079] see Figure 1 to Figure 8 , a general operating device for an overdrive gearbox, comprising a gearbox selector shift shaft 1 and a selector shift rocker 2 and a selector shift dial 4 arranged on it, one end of the gearbox selector shift shaft 1 passes through The gear-selecting rocker arm 2 is respectively matched with the gear-selecting flexible shaft and the gear-shifting flexible shaft. The flexible shaft of the gear shifts through the overdrive gear conversion device 11 and the gear selection rocker 2. The overdrive gear conversion device 11 includes a shift fork 3, and the upper end of the shift fork 3 is connected to the gear selection rocker arm. 2, the lower end of the shift fork 3 and the lower end of the selector rocker arm 2 are in drive fit; the shift fork 3 includes a U-shaped fork lever 31, a general gear selector lever 32, a direct gear overdrive The selector lever 33 and the transmission push rod 34, the general gear selector lever 32 and the direct gea...

Embodiment 2

[0093] Embodiment 2 is basically the same as Embodiment 1, and its difference is:

[0094] The overdrive gear conversion device 11 also includes a shift booster 6, the power output end of the shift booster 6 is fixedly connected to one end of a transmission push rod 34, and the other end of the transmission push rod 34 is connected to a U-shaped The middle part of the fork rod 31 is fixedly connected, the middle part of the transmission push rod 34 is in transmission cooperation with the shift flexible shaft, and the shift booster 6 is a pneumatic device;

Embodiment 3

[0096] Embodiment 3 is basically the same as Embodiment 1, and its difference is:

[0097] The gear selection and shift shaft 1 of the gearbox is a circular tube structure, and the gear selection rocker 2 and the shift dial 4 are welded on the outer wall of the gear selection and shift shaft 1 of the gearbox. An interlock seat 5 is sheathed on the shaft 1, and the selector shift dial 4 passes through the interlock seat 5 and then cooperates with the shift guide block in transmission.

Abstract

A general operating device for an overdrive gearbox and a method for using the same, comprising a gearbox selector and shift shaft and a selector and shift rocker arranged on it, and a selector and shift dial. The gear shift rocker arm is respectively matched with the gear selection flexible shaft and the gear shift flexible shaft, and the other end of the gear selection and shift shaft of the transmission is matched with the gear shift guide block through the gear selection dial; the gear selection flexible shaft passes through the overdrive gear The conversion device cooperates with the gear selection rocker arm for transmission. The overdrive gear position conversion device includes a shift fork. The upper end of the shift fork is in transmission cooperation with the upper end of the gear selection rocker arm. The lower end of the rocker arm is driven and matched. When in use, the transmission direction of the gear selection shaft is changed by using the translation of the rocker arm, without changing the internal structure of the gearbox. Therefore, this design not only has a simple structure and low manufacturing cost, but also can realize the gear sequence reversal of the gearbox without changing the internal structure of the gearbox.

Description

technical field [0001] The invention relates to a transmission control device, in particular to a general control device for an overdrive transmission and a method for using the same, which is particularly suitable for simplifying the structure of the transmission and reducing design and manufacturing costs. Background technique [0002] With the vigorous development of the automobile market, a basic gearbox needs to be equipped with two or more speed ratios of direct gear and overdrive gear to meet the needs of market segments. With the improvement of the market's requirements for the comfort of automobile shifting, the shift assist system is also more and more widely used in the transmission shifting system, especially in the commercial vehicle market. Since the gear arrangement of the overdrive gearbox is different from that of the direct transmission, the control mechanism used in the original direct transmission gearbox cannot be directly adapted to the overdrive gearbo...
