Embodiment Construction

[0036] It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0037] A vehicle transfer case 1000 according to an embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0038] The vehicle transfer case 1000 according to the embodiment of the present invention may include: a motor 10 , a drive disc 20 , a low gear shift fork 30 , a high gear shift fork 40 and two four-wheel drive shift forks 50 . Such as figure 1 As shown, the drive disc 20 is installed on the motor shaft 11 of the motor 10 , and when the motor 10 works, the motor 10 can drive the drive disc 20 to rotate. Specifically, such as figure 2 As shown, a through hole 24 may be provided at the center of the driving disc 20, wherein the through hole 24 may be a polygonal hole, such as figure 2 As shown, the through hole 24 is a hexagonal hole, so...

Abstract

The invention provides a vehicle transfer case. The vehicle transfer case comprises a motor, a drive disk, a low-gear fork, a high-gear fork and a two wheel drive fork / four wheel drive fork, wherein the drive disc is mounted on a motor shaft of the motor; a low-gear molded line structure, a high-gear molded line structure and a two wheel drive / four wheel drive molded line structure are arranged on the drive disk; the low-gear molded line structure is provided with a low-gear section; the high-gear molded line structure is provided with a high-gear section; the two wheel drive / four wheel drive molded line structure is provided with a two wheel drive section and a four wheel drive section; the low-gear fork is matched with the low-gear molded line structure in a movable manner; the high-gear fork is matched with the high-gear molded line structure in a movable manner; when the low-gear fork is in the low-gear section, the vehicle runs at the low gear; when the high-gear fork is in the high-gear section, the vehicle runs at the high gear; the two wheel drive fork / four wheel drive fork is matched with the two wheel drive / four wheel drive molded line structure; and the drive disk can replace a camshaft in the prior art, so that the vehicle transfer case is reliable in drive, simple in structure and high in drive efficiency.

Description

technical field [0001] The invention relates to the technical field of a vehicle transfer case, in particular to a vehicle transfer case. Background technique [0002] In the related art, the gear shifting mechanism of the vehicle transfer case usually uses a single motor to drive the shift cam or double motors to directly drive the shift shaft to realize the switching between the high and low gears of the transfer case and the two-wheel drive and four-wheel drive. The method of driving the shift cam with a single motor, on the one hand, it is difficult to process the shift cam profile, it is difficult to control, and the manufacturing cost is high; on the other hand, the shift fork shaft pin or the shift fork pin is embedded in the cam profile surface Shifting gears on the top, due to the high friction, the shifting efficiency is low. In the way of dual motors directly driving the shift shaft, the entire structure of the motor and the shift mechanism is relatively complica...
