The discipline of "Mechanical Engineering" was founded in 1952, and it is the only major of construction and road construction machinery in Xi 'an Highway College in Asia. 198 1 year enrolled master students, 1986 awarded master degree, 1990 awarded doctor degree. In 2003, he was awarded the post-doctoral mobile station of the first-class discipline of mechanical engineering, and in 2005, he was awarded the doctor's degree of the first-class discipline. It is the first batch of key disciplines of the Eighth Five-Year Plan of the former Ministry of Communications and the national "265433". This subject serves the field of traffic engineering, and has distinct characteristics and advantages in construction machinery, commercial vehicles and highway traffic industries. It studies and solves theoretical and technical problems in the design, manufacture, inspection, testing, use, maintenance and management of construction machinery and commercial vehicles. At present, this discipline has formed the following seven two disciplines directions: mechanical design and theory, mechanical manufacturing and automation discipline direction, mechanical and electronic engineering, construction machinery, vehicle engineering, mechanical engineering materials and vehicle new energy and energy-saving engineering. The college has a doctoral program in the first-class discipline of "mechanical engineering"; Post-doctoral research mobile station of "mechanical engineering" first-class discipline; Four doctoral and academic postgraduate majors in mechanical design and theory, mechanical and electronic engineering, mechanical manufacturing and automation, and construction machinery (self-designed); Full-time master degree in mechanical engineering; Master's degree in mechanical engineering; The postdoctoral mobile station of mechanical engineering was rated as an excellent workstation in Shaanxi Province.

The college has four undergraduate majors: mechanical engineering, mechatronics engineering, mechanical design and manufacturing and its automation, and industrial design, covering six professional directions: mechanical manufacturing and its automation, intelligent manufacturing engineering, mechatronics engineering, engineering machinery, traffic construction and intelligent equipment, and industrial design. In addition, there is a foreign student class specializing in mechanical design, manufacturing and automation. Among them, mechanical design, manufacturing and automation are national first-class undergraduate majors, while mechanical design, manufacturing and automation and mechanical and electronic engineering are national characteristic majors. At present, there are 2025 undergraduates, 74 postgraduates1person and 36 international students. In recent years, the average employment rate of graduates has stabilized at over 95%, the online rate of postgraduate students has exceeded 30%, and the overseas study rate of undergraduate graduates has exceeded 5%.
