Technical field
The utility model is related to technical field of motorcycles, more particularly to a kind of one kind that can reduce shifting amount and have no abnormal sound is rubbed
Motorcycle back vent assembling structure.
Background technology
Back vent is motorcycle important component, belongs to suspension arrangement；Referring to Fig. 1, it includes two leg pipes 101, the front end of two leg pipe 101
Portion is fixedly connected with central siphon 102 respectively, and rear end sets trailing wheel axis hole, for installing trailing wheel.In assembling process, central siphon 102 is enclosed on
Coordinate on rear fork of motorcycle axle with it, and there is rational gap between central siphon and rear fork shaft.In the prior art, the central siphon of back vent
102 are assemblied in frame assembly by rear fork shaft（Including support frame 103 and installing plate 104）On, between central siphon 102 and rear fork shaft
Provided with bushing 105 and nylon sleeve 106, to prevent dust, in the entirety of central siphon 102, bushing 105 and nylon sleeve 106 formation
Be provided at both ends with dust cap 107.Require, make because the gap between tolerance present in assembling process and each part coordinates
The axial movement value for obtaining whole back vent is larger, has reached 2-3mm, so as to cause vehicle in the process of running, a left side occurs in back vent
The phenomenon moved right；When central siphon end face and dust cap medial surface are contacted, two metal coverings have relative motion will send chirp
Sound, and may whole dust cap back vent can be followed to rotate, at this moment dust cap lateral surface contacts rotation with the installing plate of vehicle frame
Turn, can also produce abnormal sound.Simultaneously as play is apart from excessive, it is easy to cause in vehicle running to nylon sleeve and lining
The abrasion of set, and then reduction of service life, influence the stability and security of vehicle.
Utility model content
For deficiencies of the prior art, the purpose of this utility model is how to solve after existing back vent assembling
The shifting amount of presence is big and the problem of abnormal sound there is provided a kind of rear fork of motorcycle assembling structure, vehicle can be effectively reduced and run
The shifting amount of back vent in journey, so as to reduce the abrasion to nylon sleeve and bushing, improves the stability and security of vehicle operation,
And effectively it can prevent abnormal sound from producing.
In order to solve the above-mentioned technical problem, the technical solution adopted in the utility model is such：A kind of rear fork of motorcycle
Assembling structure, including frame assembly, back vent and rear fork shaft, the frame assembly include support frame and installing plate, in support frame
Two ends be welded with rear fork shaft positioning bushing；The back vent includes two leg pipes, and the front end of two leg pipes is respectively fixed with an axle
Pipe, and the axial line coincidence of two central siphons；The rear fork shaft positions to fix with two installing plates after bushing and central siphon through rear fork shaft to be connected
Connect；It is characterized in that：Gap between the outer end of the central siphon and installing plate is 0.5-1mm；Set between central siphon and rear fork shaft
There are external bushing and neck bush, wherein, the external diameter of external bushing is more than the external diameter of neck bush；The neck bush is located at external bushing and back vent
Between axle positioning bushing, its one end is close to rear fork shaft positioning bushing, and the other end is close to external bushing, and external bushing is in inner sleeve
In the presence of be close to connecting plate；The outer end correspondence external bushing of the central siphon is provided with limited impression, and the external bushing is located at the limit
In the groove of position；The depth of the limited impression is less than the length of external bushing, and the length and the depth difference of limited impression of external bushing
For 0.1-5mm；The first sealing ring is provided between external bushing and central siphon, first sealing ring is fixedly connected with external bushing；Institute
State the gap that the distance between the inner and support frame of central siphon are more than between its outer end and installing plate；One is provided with the inner of central siphon
Seal groove, is provided with the second sealing ring, second sealing ring is set on neck bush, and is fixed with neck bush in the seal groove
Connection；
Nylon sleeve is provided between neck bush and central siphon, the two ends of the nylon sleeve and the first sealing ring and second are close
Lubricating grease is filled with cavity between seal.
Further, the length of the external bushing is 1/4-the 1/3 of neck bush length.
Further, the gap between the outer end of central siphon and installing plate is 1mm；The length of external bushing and the depth of limited impression
Degree difference is 0.5mm.
Further, on external bushing, the position of the first sealing ring of correspondence is provided with locating slot, and first sealing ring is installed
In the locating slot.
Compared with prior art, the utility model has the following advantages that：
1st, simple in construction, shifting amount is small, and the gap between central siphon outer end and installing plate is 0.5-1mm, so that central siphon exists
During left and right is altered, the distance of play is 1mm to the maximum, the transmission amount of back vent in vehicle running is greatly reduced, so as to subtract
Few abrasion to nylon sleeve and bushing, and then reduction of service life, influence the stability and security of vehicle.
2nd, by the way of external bushing and neck bush are combined, and stopper slot is set in the outer end of central siphon, forms limiting stand
Rank, so as to give central siphon spacing；When whole back vent or so play, after existing shifting amount is eliminated, external bushing and central siphon
Limited step contact is spacing, though it is metal covering, because contact area is smaller and the gap（Cavity）It is interior to be filled with lubricating grease,
So abnormal sound will not be produced；Because the length of external bushing is more than the depth of limited impression, therefore, when limited step is locked with outer lining
During patch, still there is 0.1-5mm gap, so that central siphon outer face and installing plate between the outer end of central siphon and installing plate
Medial surface can not possibly be contacted, so that the generation of abnormal sound is avoided, also with regard to the hidden danger without abnormal sound.
3rd, dust-proof end cap is replaced using sealing ring, not only effectively increases dust-proof effect, and further avoid abnormal sound
Generation.
