Abstract

The invention discloses an upper fixing plate of a speed change control mechanism. The upper fixing plate is in an integral structure and is characterized in that: a middle hole is arranged at the middle part of the upper fixing plate; four first fixing holes are arranged at four corners of the upper fixing plate respectively; a threading hole is formed at the middle part of one side of the upper fixing plate; a second fixing hole is arranged at the middle part of the other side of the upper fixing plate; reinforcing bulges are arranged at the upper part and lower part of the upper fixing plate; and the peripheral edge of the upper fixing plate is provided with a sealing groove surrounding the upper fixing plate. Through the structure, the upper fixing plate of the speed change control mechanism is matched with a lower fixing plate of the speed change control mechanism, and the dust and sundries are prevented from entering the speed change control mechanism easily so that each transmission pair of the automobile speed change control mechanism moves flexibly.

Description

technical field [0001] The invention relates to an automobile part, in particular to a fixed plate on a multi-gear heavy-duty truck transmission control mechanism. Background technique [0002] It is a trend for heavy trucks to develop into multiple gears. However, the corresponding variable speed control mechanism moves frequently in each rotation range, is prone to failure, and has a short life cycle. Contents of the invention [0003] The purpose of the present invention is to provide an upper fixed plate of a multi-gear heavy truck transmission control mechanism with high service life. [0004] In order to achieve the above object, the present invention has an integrated structure, a middle hole is provided in the middle of the upper fixing plate, four first fixing holes are respectively arranged at the four corners of the upper fixing plate, and the threading holes are arranged in the middle of one side of the upper fixing plate position, the second fixing hole is l...
