Gear selection rocker arm structure and shift tower

Abstract

The invention provides a gear selecting rocker structure and a gear shifting tower. The gear selecting rocker structure is used for being installed on the gear shifting tower for executing gear selecting operation. The gear selecting rocker structure comprises a shell and a gear selecting rocker, the gear selecting rocker is in a V shape and is provided with a first arm part and a second arm part, the first arm part and the second arm part are connected at a folding point of the V shape, and the gear selecting rocker is installed on the shell at the folding point in a manner of pivoting relative to the shell. The gear selecting rocker structure further comprises a connecting rod which comprises a first connecting rod end and a second connecting rod end, the connecting rod is used for transmitting gear selecting motion of the gear selecting rocker to a gear shifting shaft connected with the second connecting rod end, and the first connecting rod end is connected with the first arm part of the gear selecting rocker; and when the second arm part of the gear selecting rocker is driven, the first arm part of the gear selecting rocker drives the gear shifting shaft to move through the connecting rod. By means of the gear selecting rocker structure and the gear shifting tower, the overall height of the gear shifting tower structure can be decreased.

Description

technical field [0001] The invention relates to the technical field of automobile gearboxes, in particular to a gear selection rocker arm structure in a gear shift tower of a gearbox and a gear shift tower provided with the gear selection rocker arm structure. Background technique [0002] figure 1 A form of gear arrangement for a manual transmission of an automobile is shown. from figure 1 It can be seen from the figure that the six gears from ① to R (reverse) are divided into three gear groups, and each gear group includes two gears. Specifically, ① and ② are One group, ③ file and ④ file are a group, ⑤ file and R file are a group. [0003] When performing a gear shift operation, firstly the shift handle needs to be shifted to the neutral position of the gear group where the target gear is located, and then the shift handle is shifted to the target gear. For example, when it is necessary to shift from ② to ③, the driver needs to first shift the shift handle from ② to th...

However, figure 2 The shift tower structure shown has the disadvantage that it is difficult to reduce the height of the entire shift tower structure

The reason is that due to structural limitations, it is difficult to change the position between the cup-shaped body 101 and the housing 103, so it is difficult to change the height of the first end of the gear selection rocker arm 102 relative to the housing 103.

If the gear selection rocker arm is installed at the lower position of the housing 103 in order to reduce the height, it is difficult to ensure that the position of the first end of the gear selection rocker arm is at the same height as the position of the inflection point, and the gear selection rocker arm is forcibly lowered on the shell. The installation position on the body 103 will sacrifice the action conversion efficiency during gear selection, and may even cause poor gear selection
