AI Technical Summary

Technical Problem

In special vehicles, traditional gearboxes and transfer cases require a lot of space, which makes installation difficult. This is especially true when the vehicle body is small and the overall layout space is limited, which severely restricts the flexibility of the power system layout.

Method used

An integrated transmission structure was designed, which directly drives the left and right wheels through the left and right input shafts respectively, eliminating the transfer case and the drive shaft connecting the transmission and the transfer case. Power transmission and support are achieved by using a reduction gear and a supporting shaft, realizing independent torque transmission and deceleration control.

Benefits of technology

It significantly reduces the overall size of the transmission system, making it suitable for special vehicles with compact bodies and limited chassis space. It improves the installation flexibility and space utilization of the power system, meets the driving torque requirements of special vehicles, and enhances the reliability and stability of operation.

Abstract

This utility model discloses a transmission structure for special vehicles, including a gearbox. The gearbox includes a housing, a left input shaft and a left output shaft, as well as a right input shaft and a right output shaft. The left input shaft and the left output shaft are drive-connected, and the right input shaft and the right output shaft are drive-connected as well. The left output shaft is used to drive the left wheel, and the right output shaft is used to drive the right wheel. The left input shaft is used to drive the first drive structure so that the first drive structure drives the left wheel to roll through the gearbox. The right input shaft is used to drive the second drive structure so that the second drive structure drives the right wheel to roll through the gearbox. The integrated design of the gearbox directly eliminates the transfer case and the drive shaft connecting the gearbox and the transfer case. The torque does not need to be distributed through the transfer case, significantly reducing the overall volume of the transmission system. It is suitable for special vehicles with compact bodies and limited chassis space.
