The invention provides a transfer case equipped with a center limited slip differential, comprising a case body fixedly connected to a gearbox, a main transmission shaft connected to the output end of the gearbox, and two main change-speed gears sleeved at the two ends of the external splines of the main transmission shaft. A joint sleeve is sleeved in the ring of a shifting fork. Two auxiliary change-speed gears are engaged with the main change-speed gears, a third worm shaft is rotationally cooperated with a first half-shaft worm gear, a fourth worm shaft is rotationally cooperated with a second half-shaft worm gear, the third worm shaft and the fourth worm shaft are reversely and intersectionally connected, the half-shaft worm gears are rotationally fixed in a casing, a half-shaft joint gear is rotationally fixed to the casing and the half-shaft worm gears and is provided with external splines same to that of the half-shaft worm gears and the casing, the half-shafts are connected to the half-shaft joint gear via the splines. The transfer case provided is applied on a 4-wheel driven car to respectively realize the functions of high gear, low gear, neutral, front-drive, rear-drive, four-drive and the four-drive locking of the center differential, moreover, the transfer case provided can dynamically distribute the front and rear powers and has a limited slip self-locking function.
Description
Technical field [0001] The technical field of machinery of the present invention particularly relates to a transfer case with an intermediate anti-skid differential. Background technique [0002] The transfer case is the main part of the four-wheel drive car driving the car. Its function is to transmit power to the front and rear half shafts, and can realize the functions of two-wheel drive or four-wheel drive and auxiliary gearbox. However, the existing technology provides The transfer case can only be locked in two-wheel drive and four-wheel drive or can only be full-time four-wheel drive. Summary of the invention [0003] The invention provides a transfer case, which can respectively realize the functions of high gear, low gear, neutral gear, front drive, rear drive, four-wheel drive and four-wheel drive to lock the middle differential, dynamic distribution of front and rear power and anti-skid self-locking function [0004] In order to achieve the above objectives, the present ...
