Principle of the present utility model is described as follows：
Existing slidingtype intermediate support structure middle (center) bearing can move along the axle journal of power transmission shaft, using in power transmission shaft
Cheng Zhong, bearing and the relative slip of axle journal can cause journal wear, and then lead to the imbalance of power transmission shaft motion, thus can cause
Power transmission shaft produces shake, such design not only bearing, axle journal service life short, and the shake of car load can be caused, comfortable
Property is poor.A kind of fixed intermediate support structure of the design adopts bearing and axle journal interference fit, bearing and center support bearing
Seat interference fit, the front end face of bearing inner race is mutually pushed against with the rear end face of axle journal stage portion, the rear end of bearing inner race
Face is mutually pushed against with the front end face of No. two stage portion of bead, and bearing outer ring two ends are by two being stuck in center support bearing seat
Jump ring carry out spacing, and then realize spacing to bearing；To bearing spacing not only solve bearing relative with axle journal slide make
Become the problem of abrasion, and solve the problems, such as that power transmission shaft motion imbalance causes shake.
Simultaneously for the shake of power transmission shaft in car load running, the design adopts the top setting of intermediate support rubber
Pants type groove, the bottom setting yi word pattern groove of intermediate support rubber, intermediate support rubber achieves the non-thread of rigidity in Z-direction
Property, X to（Along drive shaft axis direction）Rigidity is less, for absorbing the displacement of play in X direction in vehicle travel process
（Because bearing and power transmission shaft axle journal are interference fit it is impossible to there is relative motion with power transmission shaft）, effectively alleviate car load
Jitter phenomenon.
In addition, compared with prior art, the screwed hole of the intermediate support assembly being connected with suspension bracket is arranged at down by the design
On the inner peripheral surface of support, decrease the contour dimension of intermediate support outside framework so that the weight of intermediate support assembly reduces, with
When, such design saves the installing space on vertical direction so that the space of intermediate support attachment structure occupancy is less, has
Optimization beneficial to power transmission shaft installation site.In vehicle travel process, partial vibration can pass to car body by intermediate support outside framework,
The connection between upper cover plate and lower carriage if things go on like this can be caused to be damaged, so that the reliability of intermediate support outside framework
Low, the design improves the bonding strength of upper cover plate and lower carriage so that reliability is high by a thread bush.Intermediate support is tied
In structure installation process, adjust the installation site of intermediate support assembly by a slotted hole and No. two slotted holes, reduce suspension bracket
Species so as to versatility is good, meanwhile, a slotted hole and No. two slotted holes can be also used for absorbing rigging error so that each portion
Part assembling effect is good.
