Embodiment Construction

[0026] Next, the mounting structure of the transmission 1 according to the embodiment of the present invention will be described with reference to the drawings.

[0027] refer to figure 1 The speed changer 1 is a so-called IVT (Infinity Variable Transmission: A type of infinite transmission).

[0028] The transmission 1 is of a four-joint linkage type and has an input shaft 2 and an output shaft 3 . The input shaft 2 is transmitted with a driving force from a main drive source ENG (not shown) such as an internal combustion engine or an electric motor, and rotates about a rotation center axis P1 in the transmission case 80 . The output shaft 3 is arranged in the transmission case 80 parallel to the rotation center axis P1, and transmits rotational power to drive wheels (not shown) of the vehicle through a differential gear (not shown). In addition, a propeller shaft may be provided instead of the differential gear.

Abstract

The invention provides a mounting structure of a transmission capable of suppressing the weight increment of a transmission shell when a middle part of an input shaft is supported. The transmission (1) has: the transmission shell (80) having a loading mounting part (103) mounted on a vehicle frame (101) through a loading mechanism (102); and the input shaft (2) which rotates in the transmission shell through a driving force from an engine; and a plurality of transmission assemblies (20-1 - 20-6) housed in the transmission shell and transmitting the rotation of the input shaft to an output shaft (3). The input shaft is supported on the transmission shell in a free rotatable manner through a first bearing (91) and a second bearing (92) which respectively support both shaft ends and a third bearing (93) which supports the middle part. At least one transmission assembly is respectively arranged between the first bearing and the third bearing as well as between the second bearing and the third bearing. The loading mounting part is configured to be overlapped with the third bearing in the axial direction of the input shaft.

Description

technical field [0001] The invention relates to an installation structure of a transmission, which includes a loading installation part arranged on a transmission housing. Background technique [0002] Conventionally, there is known a transmission that has: an input shaft that is rotated by transmission of a driving force from an engine (drive source) provided in a vehicle; The rotations are respectively transmitted to the output shafts. Each speed change assembly includes: a crank rocker mechanism, which has a radius of rotation adjustment mechanism, a swing rod and a connecting rod. The radius of rotation adjustment mechanism can freely adjust the radius of rotation of the rotating part, and the rotating part can be The rotation center axis of the input shaft rotates around the center, the swing rod is provided with a swing end and is pivotally supported on the output shaft in a freely swinging manner, and one end of the connecting rod is adjusted to the radius of rotation...
