What is transmission design requirements?

.

1 transmission design requirements

transmission design requirements are:

1, to ensure the car has high power and economic indicators. In the overall design of the car with the car load in accordance with requirements, engine and vehicle parameters to select a proper transmission gear ratio number and to meet this requirement.

2, reliable manipulation of light. In the driving process, there will be no transmission skip shift, gear disorder, shift shock occurring phenomena. With the widespread automobile, manipulation of light, safe, low labor intensity required driving increasingly more important, and the introduction of a technique to synchronize or automatically preselected shift pneumatic, semi-automatic shift, etc., to solve the above need.

3, small size and light weight. The main parameters affecting this indicator is the center of the transmission distance. High quality steel, with a reasonable heat treatment, a suitable tooth design, improve accuracy of the gear selection and tapered roller bearing center distance can be reduced.

4, high transmission efficiency. In order to reduce the loss of meshing gears, should direct gear. Improve manufacturing precision and quality of the parts installed, appropriate lubricant can improve the transmission efficiency.

5, noise. Reasonable variation coefficient selection and use of helical gears, to improve the mounting rigidity and manufacturing precision can be reduced gear noise.
