Problems solved by technology
[0003] Judging from the current situation, there are more foreign developments, but the product design is more complicated and the price is higher, so it is difficult to meet the needs of the domestic market.
[0004] The self-development ability of domestic transmission assemblies is relatively weak, and has not yet developed its own six-speed transmission assembly products

The invention belongs to the technical field of automobile equipment and relates to a six-gear transmission assembly for a medium truck and a light truck. The six-gear transmission assembly for the medium truck and the light truck comprises a first shaft assembly, a second shaft assembly, a middle shaft assembly, a gear shifting fork shaft assembly and a gear shifting selecting mechanism. The six-gear transmission assembly for the medium truck and the light truck is assembled through four-shaft integration and vertical split type. The first shaft assembly is arranged in a front shell body of a transmission. The second shaft assembly is provided with a gear assembly of different gears, a synchronizer gear hub and a synchronizer. The middle shaft assembly is provided with a middle shaft constant mesh gear, a sixth-gear gear, a third-gear assembly, a third-gear synchronizer, a fourth-gear gear synchronizer and a fourth-gear gear assembly. The gear shifting selecting mechanism is provided with a gear shifting fork shaft joint, a reverse gear shifting fork assembly, a first-gear shifting fork assembly, a second-gear shifting fork assembly, a third-gear shifting fork assembly, a fourth-gear shifting fork assembly, an interlocking sleeve, a fifth-gear shifting fork assembly and a sixth-gear shifting fork assembly. The gear shifting selecting is composed of a shifting shaft assembly, a left guide sleeve support and a right guide sleeve support. The six-gear transmission assembly for the medium truck and the light truck is simple in structure, light in operation, low in product faulty probability, and capable of saving oil to a large extent, improving power, boosting and operating performance of an automobile.
Description
technical field [0001] The invention belongs to the technical field of automobile equipment, and in particular relates to a six-speed transmission assembly for medium and light trucks. Background technique [0002] At present, most of the transmission assemblies used by medium and light trucks on the market are five-speed transmissions. In order to adapt to the requirements of more environmental protection, energy saving, and more portable and flexible operation of automobiles under the new situation, it will always become a trend to use six-speed transmissions for medium and light trucks, and domestic and foreign auto parts fields are competing to develop six-speed automobile transmissions. to make. [0003] Judging from the current situation, there are many developed abroad, but the product design is relatively complicated and the price is relatively high, so it is difficult to meet the needs of the domestic market. [0004] The self-development capability of domestic tr...
