A kind of four-drive transmission system of children's car

Abstract

The invention provides a four-wheel drive transmission system for a juvenile automobile and belongs to the technical field of vehicles. The four-wheel drive transmission system for the juvenile automobile comprises two motors; two sides of each motor are symmetrically provided with two drive wheels; at least one motor is connected with two corresponding drive wheels through a differential respectively; the motor is connected with the differential through an input shaft with a master gear; the differential is symmetrically provided with a first half axle and a second half axle; the first and second half axles are respectively connected with two corresponding drive wheels through a transmission shaft; the differential comprises an outer shell and an inner shell arranged in the outer shell; the outer side wall of the inner shell is provided with a driven gear; the differential is also provided with a differential lock capable of locking the first and second half axles and the inner shell; each motor comprises a stator component, a rotor component and an electric brush component. The four-wheel drive transmission system for the juvenile automobile has the advantages of reasonable design, simple structure, locking function of the differential and the like.

Description

technical field [0001] The invention belongs to the technical field of vehicles and relates to a four-drive transmission system of a children's car. Background technique [0002] In daily life, children like to sit and play in toy cars, and there are various types of children's toy cars, but they are simple in structure and single in function, which cannot improve children's interest in games and does not have the driving reality of existing adult cars . In addition, since children cannot drive adult cars, someone has designed a simulated children's toy car. It looks more like an adult car than ordinary toy cars, but its internal operation is still very simple. An adult car feels a far cry from that. [0003] Kid's Car is a product between children's toy cars and adult cars. It is an adult car driving simulator, and the feeling of driving a kid's car is close to that of driving an actual adult car. Children's cars have many functions and advantages such as mobilizing chil...

AI Technical Summary

Problems solved by technology

[0005] The transmission system of a car is generally composed of a differential, a motor, and driving wheels. In the prior art, a differential is not added to a children's toy car, and there is no four-drive transmission system. Children's toy cars often only pass through The simple motor directly drives the driving wheels forward, the design is unreasonable, and the stability performance is not good, and the structure of the four-drive transmission system of an adult car is too complicated to be suitable for children's cars
