The support member 6 is connected to a support pad 7 to support the front end of the gear box, and the support member 6 is provided with a plurality of first connecting holes 6-1 to adjust the position of the support pad relative to the support member.
[0043] In order to meet the support requirements of the front end of the gear shaft of different vehicle models, the support member 6 is provided with multiple first connecting holes 6-1, specifically six. The first connecting holes pass through the thickness direction of the support member, and all the first connecting holes are arranged along the length direction of the support member 6. The interval between two adjacent first connecting holes 6-1 is set, and the support pad is fixedly connected to the support member through the first connecting hole to facilitate stable support of the front end of the gear box.
