In above-mentioned AMT speed changer in the mounting structure of release bearing, to be that center line is rounded with the axle center of bearing support be distributed on the base described boss.
In the mounting structure of release bearing, the quantity of described boss is three to six in above-mentioned AMT speed changer.
In the mounting structure of release bearing, described bearing support has the position-limited edge edge that some roads axially are provided with and outwards turn down away from the end of base in above-mentioned AMT speed changer.Position-limited edge has guaranteed the functional reliability of release bearing along the release bearing that is installed on the bearing support outer circumferential face has been played spacing anticreep effect.
In the mounting structure of release bearing, described spacing number of edges is two to four roads in above-mentioned AMT speed changer, and position-limited edge is along being distributed on the outer circumferential face of bearing support.
In the mounting structure of release bearing, described fastening piece is bolt or screw in above-mentioned AMT speed changer.
Compared with prior art, the mounting structure of release bearing has the following advantages in the AMT speed changer that provides of the utility model:
1, this mounting structure bottom bracket is fixed on the front case through fastening piece; Replaced in the past the cylinder boss that fuses with front case; Bearing support easy to assembly, when maintenance, the dismounting of bearing support is also very convenient in addition; Dismounting can be observed the component in the front case behind the step very intuitively, can find quickly that fault sentences just maintenance.
2, this mounting structure bottom bracket adopts the segmentation fine blanking technology to process, and can guarantee that bearing support has high machining accuracy and less surface roughness, thereby reduce release bearing frictional force in the course of the work, makes separation process lighter.
3, be processed with boss through fine blanking technology on the bearing support, the precision of boss is very high, and boss embeds the groove at front case or oil sealing place, has guaranteed the coaxality of the input shaft bore position on bearing support and the front case, makes the good stability of working procedure.
4, be processed with the position-limited edge edge on the bearing support, position-limited edge makes the functional reliability of release bearing good along release bearing has been played spacing anticreep effect.
