Resumen
The present work aims at the desing and construction of a transmission system for a Student formula single-seater racing vehicle, which is intended to contribute with the first vehicle of this type for the School of Automotive Engineering at the ESPOCH. The work began by making the selection of the differential mechanism to be acquired which had to be coupled to a sprocket to ensure that the torque coming from the motor be transmitted to the drive shaft by means of a roller chain, complying with the SAE formula regulations. For the transmission system a differential mechanism of conventional type was acquired, a sump was designed and built which totally covers this one, serving as a lubricant housing that prevents the accelerated wear of the elements in contact, later a sprocket with the number of teeth suitable to satisfy a transmission ratio was acquired which allows to take advantage of the torque and power of the engine. Then the other components of the systems were selected, such as semi-axles and CV joints, a support plate was constructed to couple the transmission to the vehicle frame. Performance tests were carried out in a high and low speed regime whose results allow to demonstrate the good performance of each of the elements that make up this system. Concluding, it is highly resistant, it presents a smooth and quiet operation and due to its low weight will be a great contribution to the vehicle during the competition. Therefore, we recommend that the system be properly maintained to extend its service life.
