Abstract
The utility model discloses a kind of drive mechanisms of vehicle, including output shaft, transmission shaft and output flange, power transmission is realized in one end of output shaft and one end of transmission shaft by way of inside and outside spline fitted, the other end of transmission shaft is equipped with the first universal-joint fork, first universal-joint fork is sequentially connected by one end of cross axle and jack shaft, the other end of jack shaft is connect with one end of the second universal-joint fork, and the other end of the second universal-joint fork is sequentially connected by cross axle and output flange.The utility model transmission shaft and output shaft form transmission stretching structure, it no longer needs to be equipped with transmission stretching structure on jack shaft, the length of transmission mechanism can effectively be reduced, the inadequate problem in effective solution axial length position, hollow shaft, which can be made, in transmission shaft jackshaft reduces the overall weight of drive mechanism.
Description
Technical field
The utility model belongs to vehicle transmission field, and in particular to a kind of drive mechanism of vehicle.
Background technique
With the development of automobile, the component of arrangement is more and more, and single components the space occupied is more and more limited, vehicle
Quality more also weighs, and especially mixed dynamic, pure electric vehicle new energy vehicle increases the components such as controller, motor, power battery,
Therefore, reasonable space layout, compression components arrange the space occupied, shorten the axial space that drive mechanism occupies, and reduce
The weight of components becomes more more and more urgent demand.
Utility model content
The purpose of the utility model is to overcome the deficiencies of existing technology, provide a kind of drive mechanism of vehicle.
In order to realize the purpose of this utility model, the technical solution adopted in the utility model are as follows:
A kind of drive mechanism of vehicle, including output shaft, transmission shaft and output flange, one end of output shaft and transmission shaft
Power transmission is realized in one end by way of inside and outside spline fitted, and the other end of transmission shaft is equipped with the first universal-joint fork, the 10000th
It is sequentially connected to section fork by one end of cross axle and jack shaft, the other end of jack shaft and the second universal-joint fork
The other end of one end connection, the second universal-joint fork is sequentially connected by cross axle and output flange.
Further, there is external splines on the output shaft, there is internal spline, inside and outside spline axial sliding fit on transmission shaft.
Further, shell is equipped with outside output shaft, enclosure interior interference is equipped with sealing ring, the axis of sealing ring and transmission shaft
Body interference fit.
Further, the jack shaft is hollow structure.
The utility model transmission shaft and output shaft form transmission stretching structure, no longer need to be equipped with flexible knot on jack shaft
Structure can effectively reduce the length of transmission mechanism, the inadequate problem in effective solution axial length position, transmission shaft jackshaft
Hollow shaft, which can be made, reduces the overall weight of drive mechanism.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model preferred embodiment；
Fig. 2 is the assembling schematic diagram of the utility model preferred embodiment；
In figure, output shaft 11, sealing ring 12, shell 13, transmission shaft 21, the first universal-joint fork 22, jack shaft 23, the
Two universal-joint forks 24, cross axle 25, output flange 26.
Specific embodiment
The present invention will be further described with reference to the accompanying drawings and examples:
Embodiment: referring to the drive mechanism of attached drawing 1 and a kind of vehicle shown in Fig. 2, including output shaft 11,21 and of transmission shaft
Output flange 26, the power of output shaft 11 are provided by driving mechanism (such as gearbox or driving motor), one end of output shaft 11 with
Power transmission is realized in one end of transmission shaft 21 by way of inside and outside spline fitted, and it is universal that the other end of transmission shaft 21 is equipped with first
Section fork 22, the first universal-joint fork 22 are sequentially connected by one end of cross axle 25 and jack shaft 23, jack shaft 23
The other end is connect with one end of the second universal-joint fork 24, and the other end of the second universal-joint fork 24 passes through cross axle 25 and output flange
26 transmission connections, are transferred power in vehicle bridge by output flange 26 as a result,.
Further, there is external splines on the output shaft 11, there is internal spline on transmission shaft 21, inside and outside spline, which slides axially, matches
It closes, which cannot prevent from skidding off with the transmission stretching structure itself that output shaft 11 is formed, and need to install onboard output
Flange 26 is connect with vehicle bridge, the distance between output shaft 11 and output flange 26 is limited when installation, thus the distance of limit slippage.
Further, shell 13 is equipped with outside output shaft 11,13 inside interference of shell is equipped with sealing ring 12, sealing ring 12 with
The axle body of transmission shaft 21 is interference fitted, and shell 13, sealing ring 12 and transmission shaft 21 form sealing structure, can prevent dust or mud
Water enters in the spline fitted face of output shaft 11 and transmission shaft 21.
Further, the jack shaft 23 is hollow structure.
There is external splines on the utility model output shaft 11, there is internal spline on transmission shaft 21, output shaft 11 is packed into transmission shaft 21
In, transmission shaft 21 can be slided on output shaft 11 to eliminate the variation of axial distance, it can reduce jack shaft 23, thus
Shorten the axial length of transmission mechanism, no longer needs to be equipped with transmission stretching structure on jack shaft, can effectively reduce transmission
The length of mechanism, the inadequate problem in effective solution axial length position, transmission shaft jackshaft can be made hollow shaft and reduce
The overall weight of drive mechanism.
The basic principles and main features of the present invention and the advantages of the present invention have been shown and described above.Current row
The technical staff of industry is described in above embodiments and description it should be appreciated that the present utility model is not limited to the above embodiments
Only illustrate the principles of the present invention, on the premise of not departing from the spirit and scope of the utility model, the utility model is also
It will have various changes and improvements, these various changes and improvements fall within the scope of the claimed invention.The utility model
Claimed range is defined by the appending claims and its equivalent thereof.
