Abstract

The invention discloses an undergraduate formula car automatic gear shifting system. The system comprises a control device and an execution device; the control device comprises an ECU, a controller and a sensor; the execution device comprises a gear shifting steering engine, a clutch steering engine and a transmission mechanism; the transmission mechanism comprises a gear shifting transmission mechanism and a clutch transmission mechanism; the gear shifting transmission mechanism comprises an L-shaped driven rod, a middle connecting rod and a steering engine rocking arm; the clutch transmission mechanism comprises a steering disc and a steel wire rope; the gear shifting steering engine and the clutch steering engine are connected with the controller through circuits; the gear shifting steering engine and the steering engine rocking arm are connected through a spline; the L-shaped driven rod and the steering engine rocking arm are connected through the middle connecting rod; the middleconnecting rod is hinged with the L-shaped driven rod and the steering engine rocking arm through bolts and nuts; the L-shaped driven rod and the gear shifting shaft are connected through inner and outer splines; and the steering disc and the clutching steering engine are connected through inner and outer splines. The system has the characteristics of low weight, high integration degree, high automation degree and the like.

Description

technical field [0001] The invention relates to the technical field of research on gear shifting of a student formula racing car, in particular to an automatic gear shifting system of a student formula racing car. technical background [0002] Formula SAE (FSAE) was launched by the International Society of Automotive Engineers (SAE International) in 1978. Its concept originated from a virtual production factory, soliciting from all college student design teams to design and manufacture a small car similar to the standard formula. It has excellent performance in acceleration, braking and handling and is stable and durable enough. [0003] The 75-meter acceleration is an important item in the Formula Student racing competition, which tests the dynamic performance of the FSAE racing car, and the quality of the shift system has a particularly important impact on the dynamic performance of the racing car. Usually because the FSAE racing driver is not a professional player and th...
