Detailed description of the invention
Describe technical scheme of the present invention by specific embodiment below, following instance is only exemplary,Only can be used for explaining and technical scheme of the present invention being described, and can not be interpreted as technical solution of the present inventionRestriction.
As shown in Figure 1, one end of real axis 1 is connected with rolling bearing 2, rolling bearing 2 and the support of bearing 3Connect, the support of bearing 3 is connected with auxiliary stand 4.
What Fig. 2 represented is the structural representation of real axis 1.
What Fig. 3 A and Fig. 3 B represented is the support of bearing 3, is provided with and bearing fit hole 34, alignment pin on it32, there is installing hole 31 with the installation end face of speed changer, with the installing hole 33 of auxiliary stand installed surface.
What Fig. 4 A and Fig. 4 B represented is auxiliary stand 4, is provided with speed changer 1 peace of end face is installed on itDress hole 42 and a dowel hole 41; With the support of bearing, end face being installed has 45 and 1 of 2 screwed hole fixedPosition pin-and-hole 43.
In this application, driving shaft: the mechanism that speed changer output moment of torsion is delivered to wheel. Middle connectionAxle: connect speed changer output and right front driving shaft, and the mechanism of transmitting torque.
A kind of driving shaft intermediate connecting shaft mounting structure, comprising: real axis, rolling bearing, the support of bearing and auxiliaryHelp support, totally four parts; In this application, real axis and rolling bearing are prior art, are not described in detail.
Described real axis, with rolling bearing inner ring be interference fit, real axis two ends are with spline;
Described rolling bearing, inner ring and real axis are interference fit, outer ring and the support of bearing are interference fit;
The described support of bearing, inwall and housing washer interference fit; The described support of bearing and speed changer peaceDress end face is provided with 2 installing holes; The described support of bearing and auxiliary stand are installed end face and are provided with 2 installationsHole and an alignment pin.
