Double-drive double-bearing type racing car

Abstract

The invention discloses a double-drive double-bearing type racing car which comprises a car body, two driving wheels, two driven wheels, an electric motor, a cantilever A, a cantilever B and a car shaft, wherein the driving wheels are respectively arranged at the left and right sides of the car body along the same axial direction; the two driven wheels and the two driving wheels are respectively arranged at the same side; the car shaft is located at the middle part of the bottom of the car body; the driving wheels are connected with an electric motor shaft in a manner of key connection, the electric motor shaft is fixedly connected to the cantilever A, and the driving wheels rotate along with the electric motor; and the driven wheels are movably connected with the car shaft through the cantilever B. In the double-drive double-bearing type racing car disclosed by the invention, the driving wheels and the driven wheels at the same side of the car body are fixedly connected in a flexiblemanner of separated connection, so that no interference exists between height position states of the driving wheels and the driven wheels, and the out-of-control phenomenon of the racing car due to the unevenness of the ground is avoided.

Description

technical field [0001] The invention relates to a wheeled racing car used in college students' skill competitions, in particular to a double-drive double-support racing car. Background technique [0002] At present, wheel-driven racing cars are mostly used in college students' skills competitions. The two-wheel drive racing car is most widely used in competitions due to its simple structure and convenient manufacture. The driving mechanism of this kind of racing car is composed of a driving wheel and a driven wheel. The motor drives the driving wheel to rotate. The driving wheel rotates relative to the ground to generate power to change the motion state of the car body. The driven wheel follows the movement of the car body to support and stabilize the car body. . A two-wheel-drive race car has two drive wheels. According to the three-point support principle in mechanical engineering, if the driving wheel is arranged in the middle of the vehicle body, two driven wheels are...

Problems solved by technology

In this case, if the lifted driven wheel is in a suspended state, the driven wheel loses its role in supporting and stabilizing the car body, resulting in unstable motion of the car body

Therefore, the racing car using this rigid connection method between the driving wheel and the driven wheel can only be applied to the ideal ground with small convexity and concavity.
