The utility model discloses two cantilever type shock absorber support locking control system of pure [ electric ] motor coach overcomes the technical problem that interval and shock absorber bush inner tube between two cantilevers of shock absorber support are difficult to eliminate in clearance under shock absorber round pin, thrust sleeve, round pin axle nut, shock absorber support and shock absorber bush combined action between, can reduce shock absorber bush degree of wear and tear and can increase shock absorber bush life-span again, eliminate shock absorber support abnormal sound.
Description
The technical field is as follows:
the utility model relates to a pure [ electric ] motor coach support locking mechanism especially relates to a pure [ electric ] motor coach two cantilever type shock absorber support locking control system.
Background art:
in order to facilitate the arrangement of the shock absorber, the existing pure electric passenger car often adopts two cantilever type shock absorber supports, as shown in fig. 1. If the form is adopted, a certain gap exists between the distance between the two cantilevers of the shock absorber support and the inner tube of the shock absorber bushing due to practical factors such as assembly and manufacturing errors, the shock absorber bushing moves axially in the vehicle running process due to the existence of the gap, the axial stress of the shock absorber bushing is increased, the wear of the shock absorber bushing is accelerated, the service life of the shock absorber bushing is shortened, and meanwhile, the noise is generated due to abnormal sound of the collision stroke of the shock absorber bushing axial movement and the cantilevers of the shock absorber support.
Therefore, there is a need to improve the prior art to overcome the deficiencies of the prior art.
The utility model has the following contents:
the utility model provides a two cantilever type shock absorber support locking control system of pure [ electric ] motor coach, it can eliminate interval and shock absorber bush inner tube between two cantilevers of shock absorber support clearance between, reduces shock absorber bush degree of wear, increases shock absorber bush life-span, eliminates shock absorber support abnormal sound.
The utility model discloses the technical scheme who adopts has: the locking control system comprises a shock absorber pin, a thrust sleeve, a pin shaft nut, a shock absorber support and a shock absorber bushing, wherein the shock absorber support comprises a shock absorber support left cantilever and a shock absorber support right cantilever, the shock absorber bushing is arranged between the shock absorber support left cantilever and the shock absorber support right cantilever, the thrust sleeve is arranged in a pin hole of the shock absorber support left cantilever, and the shock absorber pin is connected with the pin shaft nut in a threaded mode after penetrating through the pin hole of the shock absorber right cantilever, the shock absorber support, the shock absorber bushing and the thrust sleeve.
Further, the axial dimension of the thrust sleeve is larger than the axial dimensions of the left suspension arm and the right suspension arm of the shock absorber support.
Further, the inner tube of the damper bushing is a metal inner tube.
Furthermore, one end of the damper pin is a bolt, and the other end of the damper pin is a thread.
Furthermore, the pin shaft nut is a Shibijia nut.
The utility model discloses following beneficial effect has: the utility model discloses two cantilever type shock absorber support locking control system of pure [ electric ] motor coach have overcome the technical problem that interval between two cantilevers of shock absorber support and clearance between the shock absorber bush inner tube are difficult to eliminate under shock absorber round pin, thrust sleeve, round pin axle nut, shock absorber support and shock absorber bush combined action, can reduce shock absorber bush degree of wear and can increase shock absorber bush life-span again, eliminate shock absorber support abnormal sound. The utility model discloses be not limited to pure [ electric ] motor coach uses, is suitable for other air brake's commercial motorcycle type equally, simple structure, low in production cost is honest and clean, and the design concept is ingenious, and is durable, and the result of use ideal is fit for generally popularizing and applying.
Description of the drawings:
fig. 1 is a schematic structural view of two cantilever type shock absorber supports.
Fig. 2 is a schematic view of a damper bracket locking control system.
The specific implementation mode is as follows:
the present invention will be further described with reference to the accompanying drawings.
The utility model discloses two cantilever type shock absorber support locking control system of pure [ electric ] motor coach includes shock absorber round pin 1, thrust sleeve 2, round pin axle nut 3, shock absorber support 4 and shock absorber bush 5, and shock absorber support 4 includes shock absorber support left cantilever 41 and shock absorber support right cantilever 42, and the inner tube of shock absorber bush 5 is shock absorber bush metal inner tube 51, and the one end of shock absorber round pin 1 is the bolt, and the other end is the screw thread. The shock absorber bush 5 is arranged between the shock absorber support left cantilever 41 and the shock absorber support right cantilever 42, the thrust sleeve 2 is arranged in a pin hole of the shock absorber support left cantilever 41, the shock absorber pin 1 penetrates through the pin hole of the shock absorber support right cantilever 42, and the shock absorber pin penetrates through the shock absorber support 4, the shock absorber bush 5 and the thrust sleeve 2 and then is in threaded connection with the pin shaft nut 3.
The axial dimension of the thrust sleeve 2 is larger than the axial dimensions of the left suspension arm 41 and the right suspension arm 42 of the shock absorber support, and the thrust sleeve 2 can axially move in the pin hole of the left suspension arm 41 of the shock absorber support and can axially move on the shock absorber pin 1.
The utility model discloses two cantilever type shock absorber support locking control system operating principle of pure [ electric ] motor coach are as follows:
and screwing the pin roll nut 3, pushing the thrust sleeve 2 to axially move along the shock absorber pin 1 by the pin roll nut 3 until the thrust sleeve pushes against the metal inner tube 51 of the shock absorber bushing 5, screwing the pin roll nut 3 to eliminate the gap 5 between the shock absorber bushing 5 and the left and right cantilevers 41 and 42 of the shock absorber bracket 4 of the shock absorber bracket, and axially locking the shock absorber bushing. The utility model discloses round pin axle nut 3 adopts and executes must jail nut.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, several modifications can be made without departing from the principle of the present invention, and these modifications should also be regarded as the protection scope of the present invention.
