Another technological innovation has achieved great achievements in the use of shaft transmissions to obtain national patents

Another technological innovation has made great achievements. Recently, the independently researched and developed axle transmission assembly for passenger cars has been granted a utility model patent certificate by the State Intellectual Property Office. The patent number is ZL 2009 2 0127674.2.

This new technology is used in the QJZJ505 shaft transmission assembly for passenger cars. The shaft transmission assembly can effectively shorten the rear suspension of passenger cars. The transmission assembly was listed as the key new product of Chongqing by the Chongqing Science and Technology Commission for two consecutive years in 2010 and 2011. Compared with traditional products of the same kind, the transmission assembly adopts a closed one-in-one overall structure, which changes the traditional way of transmission outside the box. The design is novel, ingenious, and compact, and the transfer of power is accommodated in the box. The integral structure can effectively shorten the rear suspension of the passenger car, increase the space inside the vehicle, improve the spans of the front and rear bridges, and improve the smoothness of the entire vehicle. In terms of structure, the designer changed the traditional tandem structure into a shaft-to-axis connection. The output drive gear took the power input through the two-axis active and passive wheels, and the output driven gear took the power output through a pair of shaft-crossed bevel gears, achieving 90 The power conversion, the engine is horizontal, the power output from the side of the box, completely solve the problem of long rear suspension of medium-sized rear passenger cars.
