Detailed Description
The present application is described in further detail below with reference to figures 3-4.
The embodiment of the application discloses a large-torque electric control time-sharing transfer case which can not affect the volume of the time-sharing transfer case when the bearing capacity of the time-sharing transfer case is increased.
Referring to fig. 3 and 4, the large-torque electrically controlled time sharing transfer case includes a front output shaft 101, a rear output shaft 102, a driving sprocket 103, a driven gear 104, a four-wheel drive high-speed shift assembly 105, and a rotor 106. Wherein, the driving sprocket 103 is arranged on the rear output shaft 102, the driven gear 104 is arranged on the front output shaft 101, and the driving sprocket 103 and the driven gear 104 are in transmission connection through a chain.
Both end portions of the rear output shaft 102 are provided with first bearings 107, respectively, and a rear flange 108 is connected to one of the end portions. In addition to the drive sprocket 103, a four-wheel drive high speed shift assembly 105 and a rotor 106 are also provided on the rear output shaft 102, respectively. Specifically, the four-wheel drive high-speed shift assembly 105, the driving sprocket 103 and the rotor 106 are all located between two first bearings 107, and the four-wheel drive high-speed shift assembly 105, the driving sprocket 103 and the rotor 106 are sequentially arranged along a direction from far away to close to the last first bearing 107, wherein the first bearing 107 is a bearing abutting against the rear flange 108.
It should be noted that, since the driving sprocket 103 is in transmission connection with the front output shaft 101, the position of the driving sprocket 103 on the rear output shaft 102 is the stress point of the rear output shaft 102. In the related art, disposed in order from the far side to the near side of a first bearing 107 on the rear output shaft 102 are a drive sprocket 103, a four-wheel drive high-speed shift assembly 105, and a rotor 106. In contrast, the force-bearing point on the rear output shaft 102 is moved from a position far from the two first bearings 107 to a direction close to the first bearings 107, which enables the load-bearing capacity of the position where the driving sprocket 103 is located on the rear output shaft 102 to be increased without changing the thickness of the rear output shaft 102.
It can be appreciated that the four-wheel drive high speed shift assembly 105 is connected to the rear output shaft 102 by a gear sleeve 109.
Specifically, the gear sleeve 109 is annular, and an inner spline is arranged on the inner wall of the gear sleeve. Correspondingly, the position of the four-wheel drive high-speed gear shifting assembly 105 on the rear output shaft 102 is provided with an external spline matched with the internal spline. When the sleeve gear 109 is attached to the rear output shaft 102, the sleeve gear 109 can rotate with the rear output shaft 102.
The four-wheel drive high speed shift assembly 105 includes a driving member 1051, an elastic member 1052 and a connecting member 1053. The driving member 1051, the elastic member 1052 and the connecting member 1053 are sequentially sleeved on the gear sleeve 109, and two ends of the elastic member 1052 are respectively abutted against the driving member 1051 and the connecting member 1053. The connecting piece 1053 is connected with the gear sleeve 109 in a sliding way. Specifically, one surface of the connecting member 1053 facing the gear sleeve 109 is provided with an internal spline, and correspondingly, the gear sleeve 109 is provided with an external spline adapted to the internal spline, that is, a sliding groove for allowing the connecting member 1053 to move axially along the rear output shaft 102.
The driving member 1051 is connected to a four-wheel drive high-speed shift fork 110, and the four-wheel drive high-speed shift fork 110 is connected to a return spring 111. When the driver shifts from the two-wheel drive mode to the four-wheel drive mode, the four-wheel drive high-speed shift fork 110 moves toward the return spring 111, so that the return spring 111 generates a compression amount. Then, the driver 1051 is also moved in the direction in which the four-wheel drive high speed shift fork 110 is moved. It will be appreciated that the compression of the resilient member 1052 by the driving member 1051 will produce a certain amount of compression, and then the end of the resilient member 1052 remote from the driving member 1051 will push the connecting member 1053 to move along the slide way toward the four-wheel high speed shift fork 110 under the action of the restoring force.
In order to synchronize the rotation speeds of the front output shaft 101 and the rear output shaft 102 in the four-wheel drive mode, the rotation speed of the driving sprocket 103 needs to be the same as that of the rear output shaft 102, i.e., the rotation speeds of the driving sprocket 103 and the connecting member 1053 are the same. To this end, the side of the link 1053 facing the drive sprocket 103 is internally splined. Meanwhile, the driving sprocket 103 is also provided with an external spline on one surface facing the connecting piece 1053.
When the connecting piece 1053 moves along the sliding groove towards the direction of the movement of the four-wheel-drive high-speed gear shifting fork 110, until the connecting piece 1053 is inserted into the driving sprocket 103 towards the internal spline on one surface of the driving sprocket 103, the connecting piece 1053 is connected with the driving sprocket 103 through the matching of the internal spline and the external spline, and the effect that the rotating speed of the driving sprocket 103 is the same as that of the rear output shaft 102 is achieved.
In order to save space, the rotor 106 abuts against the first bearing 107, the driving sprocket 103 abuts against the rotor 106, the gear sleeve 109 abuts against the driving sprocket 103, and the above-mentioned elastic member 1052 is preferably a conical spring in the present application.
In consideration of the maximization of the load-bearing capacity, when the position of the drive sprocket 103 on the rear output shaft 102 is designed, in addition to the drive sprocket 103 being closer to a first bearing 107 on the rear output shaft 102, the driven gear 104 drivingly connected to the drive sprocket 103 is moved toward a second bearing 112 on the front output shaft 101 so that the driven gear 104 abuts against the second bearing 112.
The implementation principle of the large-torque electric control time-sharing transfer case in the embodiment of the application is as follows: by moving the driving sprocket 103 from a position far from the first bearing 107 to a position close to the first bearing 107, and at the same time, moving the driven gear 104 in driving connection with the driving sprocket 103 from a position far from the second bearing 112 to a position close to the second bearing 112, the force bearing points on the front output shaft 101 and the rear output shaft 102 are moved to the end portions, respectively, so that the bearing capacity on the front output shaft 101 and the rear output shaft 102 is improved. Moreover, after the position of the driving sprocket 103 is changed, the structure of other parts on the rear output shaft 102 can be correspondingly simplified, so that the length of the rear output shaft 102 can be shortened by a certain amount, and the bearing capacity of the rear output shaft 102 is improved.
The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
