Throttle based on FSAE (formula SAE) racing car

Abstract

The invention relates to a throttle based on a FSAE (formula SAE) racing car. The throttle based on the FSAE racing car is characterized in that the throttle comprises a throttle shaft, a throttle body, a reel, a disc, a throttle position sensor, a bell mouth and a flow restriction valve; the throttle shaft fixed on the throttle body runs through the throttle body; the inner diameter of the throttle body is 30 millimeters; the reel, disc and throttle position sensor are coaxially arranged, wherein the reel is fixed to the first end, located outside the throttle body, of the throttle shaft, thedisc is fixed in the middle of the throttle shaft and inside the throttle body, and the throttle position sensor is fixed to the second end, located outside the throttle body, of the throttle shaft;the reel is provided with an idle adjusting bolt; the flow restriction valve and the throttle body form a integral structure with front contraction angle of the flow restriction valve to be 43 degrees, rear expansion angle of the flow restriction valve 11 degrees, minimum inner diameter of the flow restriction valve 20 millimeters, fillet radius of the flow restriction valve 16 millimeters, and the distance between the axis of the throttle shaft and the fillet centre of the flow restriction valve 45 millimeters; the bell mouth is fixed on one end, far from the flow restriction valve, of the throttle body.

Description

technical field [0001] The invention belongs to the technical field of the air intake part of the SAE powertrain, and relates to a throttle valve based on an FSAE racing car. Background technique [0002] FSAE is sponsored by the International Society of Automotive Engineers, soliciting all college student teams to design and manufacture a small formula car, which requires the car to have excellent performance in acceleration, braking, and handling, and be stable and durable enough. [0003] FSAE has been developed in China for nearly nine years, but the disc throttle has not been well developed. Based on the characteristics of the disc throttle, the throttle processed by ABS engineering plastics has insufficient rigidity and is easy to deform, and it is easy to deform when tempering. Problems such as irreparable deformation occur, affecting engine response. In terms of design, the 20mm restrictor valve restricted by the competition rules has a great hindering effect on the...

AI Technical Summary

Problems solved by technology

The existing throttle diameter has problems such as too small to affect the engine momentum, and too large to cause the throttle to be too large and inconvenient to install.
