Embodiment Construction
[0015] The present invention will be described in detail below in conjunction with accompanying drawing:
[0016] Embodiment: As shown in the accompanying drawings, the light-duty intermediate connecting fork of the integrated bearing inner ring mainly includes an intermediate bracket 1, an intermediate connecting fork 2, a lock nut 3, an intermediate spline shaft 4, and an intermediate bracket bearing 5. The outer circle of the intermediate connecting fork 2 is integrated with the intermediate support bearing 5, and the intermediate support bearing 5 is installed on the intermediate support 1, so that the intermediate support 1 and the intermediate connecting fork 2 are assembled into an assembly, reducing the number of assembly parts, thereby reducing the after-assembly At the same time, in the assembly of the drive shaft, three parts were originally required to be installed, but now only two parts are required to complete the assembly, which improves the assembly efficiency ...

The invention discloses a light intermediate connecting fork integrated with a bearing inner ring. The light intermediate connecting fork mainly comprises an intermediate bracket, an intermediate connecting fork body, a locking nut, an intermediate spline shaft and an intermediate bracket bearing, wherein the intermediate bracket bearing is integrated on the outer circle of the intermediate connecting fork body; the intermediate bracket bearing is arranged on the intermediate bracket so that the intermediate bracket and the intermediate connecting fork body can be assembled into an assembly; the intermediate connecting fork body integrated with the intermediate bracket is arranged on the intermediate spline shaft; and the locking nut locks the intermediate spline shaft to realize positioning. According to the light intermediate connecting fork, the intermediate connecting fork body is integrated with the intermediate bracket; the bearing inner ring is replaced by a ball track machinedon the outer circular surface of the intermediate connecting fork body, so that the number of parts is reduced, and the accumulated error after assembly is reduced; the assembling of a transmission shaft is reduced from three parts to two parts, so that the assembling efficiency of a transmission shaft assembly is improved; and the length of the intermediate spline shaft is shortened, so that thematerials of the intermediate spline shaft are saved, the weight of the transmission shaft assembly is reduced, the rotational inertia of the transmission shaft is reduced, the performance of the transmission shaft is improved, and the oil consumption during starting is reduced.
Description
technical field [0001] The invention relates to the field of automobile drive shafts, in particular to a light-duty intermediate connecting fork with an integrated bearing inner ring. Background technique [0002] The assembly structure of the existing transmission shaft assembly is as follows: the bearing with the inner and outer rings of the bearing is installed in the middle bracket, and the bearing and the bracket are installed together on the middle spline shaft, and the middle connecting fork is used to press the bearing to the middle spline shaft, and then use The lock nut is locked to realize the positioning of the bearing. [0003] Such a structure has the following defects: the length of the spline shaft in the middle is too long, and a lot of materials are consumed; the weight of the transmission shaft assembly is heavy, and the moment of inertia of the transmission shaft assembly is large; the precision requirements of each part are high, and there is a large cum...
