Abstract

The design task is to design for a light commercial vehicle on the main reducer, using a single-stage main reducer, the reducer is simple in structure, size and quality of small and low cost, it is widely used in a variety of small and medium-sized car. For example, car, li-

ght truck and are based on single-stage main reducer, the majority of medium-laden vehic-

les were also using this form.

According to the shape of light truck, Tread, wheelbase, minimum ground clearance, minimum turning radius, vehicle weight, loaded weight and the maximum speed, the engI-

ne's maximum power, maximum torque, displacement and other important parameters, se-

lect the appropriate The main reduction ratio. Based on the above parameters, combined w-

ith the car design, automotive theory, automobile construction, mechanical design and oth-

er related knowledge, to calculate the relevant parameters of the main reducer and demon-

strate the rationality of the design.

Its purpose is to: increase the input torque and lower speed; when the motor home also has a vertical change in the direction of the role of spin torque.

The main elements of design are: the main type of gear reducer, speed reducer forms the main, the main driving gear reducer and the driven bevel gear supporting the form of the determination of the main reduction ratio, the main reducer of the calculation to deter-

mine the load, the main reducer Basic parameters of the choice of the main reduce-rgear materials and heat treatment, the calculation of the main bearing reducer, pla-netary gear symmetric conical differential of the differential principle, symmetric co-ne of the structure of planetary gear differential, planetary symmetric cone different-ial gear design, the whole floating axle load calculation to determine the whole dia-meter floating axle option, all the strength of floating axle, the axle spline strength calculation.

Key words: The main reduction ratio; gear; driven gear; differential; Planetary Gear
