Embodiment 1

[0105] Such as Figure 5c As shown, the B clutch is a friction plate type helical surface external compression overrunning clutch, including a clutch limit device G27, a fixed assembly G22, a rotating assembly G21, a self-locking / overrunning control device and an additional clutch control device arranged on the same rotation axis.

[0106] The fixed assembly G22 includes a first force transmission drum G221 and a plurality of first friction plates G222 arranged on the first force transmission drum G221, the first friction plates G222 can slide relative to the first force transmission drum G221 in the axial direction, The first friction plate G222 and the first force transmission drum G221 rotate synchronously along the circumferential direction.

[0107] The rotating assembly G21 includes a second force transmission hub G211 and a plurality of second friction plates G212 arranged outside the second force transmission hub G211, the second friction plates G212 can slide relative...

Embodiment 2

[0120] Such as Figure 5d As shown, the B clutch is a friction disc type helical surface compression overrunning clutch, including a clutch limit device G27 set on the same rotation axis, a fixed component G22, a rotating component G21, a self-locking / overrunning control device and an additional clutch control device .

[0121] The fixed assembly G22 includes a first force transmission drum G221 and a plurality of first friction plates G222 arranged on the first force transmission drum G221, the first friction plates G222 can slide relative to the first force transmission drum G221 in the axial direction, The first friction plate G222 and the first force transmission drum G221 rotate synchronously along the circumferential direction.

[0122] The rotating assembly G21 includes a second force transmission hub G211 and a plurality of second friction plates G212 arranged outside the second force transmission hub G211, the second friction plates G212 can slide relative to the sec...

Embodiment 3

[0138] The B clutch is a friction plate type helical surface external compression overrunning clutch, which is similar to the structure of the B clutch in Embodiment 1, the difference is:

[0139] The first power transmission drum G221 is set inside the second power transmission hub G211;

[0140] The second helicoid coupler G24 is fixedly connected with the second force transmission hub G211; the second helicoid coupler G24 is located in the space formed by the second force transmission hub G211, the supporting body and the first helicoid coupler G23.

[0141] The supporting body and the first force transmission drum G221 serve as two force transmission ends of the overrunning clutch respectively.

Abstract

The invention discloses a modular combined transmission which comprises a shell and a plurality of first speed-changing modules; each first speed-changing module is composed of an input shaft, an output shaft, a three-speed device and a converter; each three-speed device is composed of a gear mechanism, a C clutch, a B clutch and a D clutch; each gear mechanism is composed of an input gear, a plurality of middle shaft gear assemblies, an output gear and a gear retainer assembly which is formed by fixedly connecting a front retainer, a middle retainer and a back retainer and is provided with two cavities; the input gear, the gear retainer assembly and the output gear are coaxially arranged and can rotate relatively between every two of the input gear, the gear retainer assembly and the output gear; the middle part of the middle retainer is provided with a center output shaft as the gear mechanism first output end; a center output shaft pipe coaxially sleeves outside the center output shaft as the gear mechanism second output end; a driving component of the C clutch is fixedly connected with an input shaft, and a driven component of the C clutch is fixedly connected with the gear retainer assembly; a rotation component of the B clutch is fixedly connected with the gear retainer assembly, and a fixing component of the B clutch is fixedly connected with a shell; the D clutch is used for switching output of the gear mechanism; and only one of the B clutch, the C clutch and the D clutch can be locked.

Description

technical field [0001] The invention relates to a gear transmission applied to a vehicle. Background technique [0002] There are two types of existing gear transmissions: fixed shaft type and planetary gear type. [0003] Such as figure 1 Shown is a schematic diagram of a fixed shaft gear transmission with three fixed gear shafts: the first shaft (input shaft) Z 1 , the second axis (output axis) Z 2 and intermediate axis Z 3 , the first axis Z 1 and the second axis Z 2 They are coaxially arranged side by side with a distance apart in the axial direction and can be rotated relative to each other. The intermediate axis Z 3 with the first axis Z 1 and the second axis Z 2 Arranged in parallel. First axis Z 1 1 gear a is mounted on the body 1 , both rotate synchronously; the second axis Z 2 3 gears b 2 、c 2 、d 2 , these three gears are sleeved on the second axis Z 2 on, and with respect to the second axis Z 2 Can rotate freely; intermediate axis Z 3 There are 4...
