Problems solved by technology

However, when the transfer case is equipped, the distributor body is often assembled first and then connected to the control components in the car. For example, a new type of transfer case with a split torque ratio of 1:1 with the patent number CN2696901 , the technical solution is: the input and output of the transfer case are designed as a flange connected to the transmission shaft through the steering joint, the planetary differential mechanism of the bevel gear pair type is adopted, the planetary carrier is input, the side gear is output front and rear, and the structure is symmetrical Arrangement to achieve the same front and rear output, the differential ratio between the front and rear output shafts is 1:1, and the locking of the front and rear differentials is realized through the fork pneumatic shift mechanism, the advantage is: the front and rear output torque ratio is 1:1 , the layout is compact and reasonable, the layout of multiple oil circuits, the lubrication is sufficient, the manufacturing difficulty adapts to the level of the machinery industry at the present stage, and the assembly is relatively simple, but when the transfer case itself is assembled and connected to the body, the internal structure is not clear. Problems such as assembly of unqualified parts and difficulty in assembly

Abstract

The invention discloses an assembling process of a four-wheel drive automobile transfer case. The assembling process comprises the following steps: step 1, putting a gear set and a gear shifting motor into an inner cavity of the transfer case; fixing the gear set on an inner cavity wall of the transfer case; step 2, connecting the gear shifting motor with one end of an ECU (Engine Control Unit) of the transfer case through a lead wire; step 3, putting a shell baffle between a transfer case main body and a transfer case front body so as to enable a vent hole to be in butt joint with the inner cavity of the transfer case and a balance cavity respectively; and step 4, embedding a screw into screw holes which are pre-formed in the transfer case main body, the transfer case front body and the shell baffle. According to the assembling process of the four-wheel drive automobile transfer case, disclosed by the invention, inner parts are connected with an automobile central control part and an assembling process of assembling the transfer case main body is carried out, so that an assembling flow is simplified and connection between the control part and the inner parts of the transfer case is simplified; and the problem that an automobile is unqualified due to the fact that the inner parts of the transfer case are damaged and the like in the assembling process is avoided and unnecessary manpower and material resource wastes are reduced.

Description

technical field [0001] The invention relates to an assembly process of a transfer case, in particular to an assembly process of a transfer case of a four-wheel drive vehicle, and belongs to the field of transfer case equipment. Background technique [0002] At present, in order to maintain stable power performance of off-road vehicles under severe road conditions and improve vehicle passability, a transfer case is usually installed on the vehicle to take power from the transmission so that the power can be distributed to the vehicle rear wheel. However, when the transfer case is equipped, the distributor body is often assembled first and then connected to the control components in the car. For example, a new type of transfer case with a split torque ratio of 1:1 with the patent number CN2696901 , the technical solution is: the input and output of the transfer case are designed as a flange connected to the transmission shaft through the steering joint, the planetary differen...
