Embodiment Construction

[0123] The following will refer to Figures 1 to 12 Embodiments of the present invention are described in detail.

[0124] First, in Figures 1 to 10 An embodiment of the present invention is shown in . The following will refer to figure 1 The overall configuration of an example vehicle transfer case according to this embodiment is described. figure 1 The transfer case shown in is, for example, a transfer case installed in a four-wheel drive vehicle based on an FR (Front Engine / Rear Wheel Drive) vehicle.

[0125] figure 1 The transfer box shown in includes input shaft 1, rear wheel side output shaft 2 (corresponding to the first output shaft), front wheel side output shaft 3 (corresponding to the second output shaft), power distribution mechanism 4, intermediate differential device 5 (corresponding to the rotation difference absorbing device), differential switching mechanism 6, auxiliary transmission mechanism 7 and control device 8.

[0126] These constituent elements ...

Abstract

A transfer has a power distribution mechanism 4 securing a two-wheel drive power transmission path that allows rotational power that is input to an input shaft 1 to be output from only a first output shaft 2, or a four-wheel drive power transmission path that allows the rotational power that is input to the input shaft 1 to be output from both the first 2 and a second output shaft 3. The auxiliary gearshift mechanism 7 includes a first auxiliary transmission 20 that is disposed in the first output shaft 2, a second auxiliary transmission 30 that is disposed in the second output shaft 3, and setting apparatuses (40, 50, 60) that cause the first 20 and the second auxiliary transmission 30 to perform gearshift operations as necessary, speed range.

Description

technical field [0001] The invention relates to a vehicle transfer case. Background technique [0002] Traditionally, various systems have been conceived in vehicles, such as part-time four-wheel drive systems, full-time four-wheel drive systems, and backup four-wheel drive systems. [0003] A part-time four-wheel drive system enables a change to a two-wheel drive mode or a four-wheel drive mode. This system is able to transmit sufficient driving force to the four wheels, so it is suitable, for example, for driving on low μ roads such as bad roads, but on the other hand, when driving over higher μ roads such as asphalt roads, for example During a bend, the rotational speed difference between the front and rear wheels increases and as a result braking phenomena occur in the vehicle. In addition, so-called cyclic torque accumulates in the drive mechanism, so that the drive mechanism enters a high-load state, which is undesirable in terms of vehicle drivability and strength o...
