Abstract

A mini electric four-wheeler equipped with a full-axle differential mechanism consists of a four-wheeler body, a storage battery, a seat, a steering wheel, a motor, a left front wheel, a right front wheel, a left rear wheel, a right rear wheel, a front bevel gear, a rear bevel gear, a left bevel gear, a right bevel gear, a differential casing, a differential bearing block, a small main chain wheel, a large main chain wheel, a main chain, a small left chain wheel, a large left chain wheel, a left chain, a small right chain wheel, a large right chain wheel, a right chain, a full axle and full-axle bearing blocks, wherein the front bevel gear, the rear bevel gear, the left bevel gear and the right bevel gear are mounted in holes in the right side of the differential casing; when the four-wheeler goes straight, the two rear wheels are identical in stress, so that the left and right bevel gears do not perform relative movement, and the left and right rear wheels rotate synchronously; when the four-wheeler turns, the left and right rear wheels are different in stress, so that the left and right bevel gears perform relative movement, and the left and right rear wheels also perform relative movement.

Description

The Miniature electric fourth wheel car of whole shaft type differential mechanism is housed

Affiliated technical field

The utility model relates to a kind of electric four-wheel vehicle, relates to specifically a kind of Miniature electric fourth wheel car that whole shaft type differential mechanism is housed.

Technical background

At present, Miniature electric fourth wheel car is seldom equipped with differential mechanism, be that what differential mechanism to be housed is also semi-shaft type, the differential design feature of this semi-shaft type is that two of left and right wheel is arranged on respectively on two semiaxis in left and right, because two of left and right wheel is not to be contained on same axle, thereby stressed be not best, the diameter volume ratio of the joint of other two semiaxis is larger, inapplicable being arranged on Miniature electric fourth wheel car.

Summary of the invention

For overcoming the stressed not good and larger deficiency of volume of semi-shaft type differential mechanism, the purpose of this utility model is to provide a kind of Miniature electric fourth wheel car that whole shaft type differential mechanism is housed, for reaching above-mentioned object, the technical solution of the utility model is: form a Miniature electric fourth wheel car that whole shaft type differential mechanism is housed by vehicle body, storage battery, seat, steering wheel, motor, the near front wheel, off-front wheel, left rear wheel, off hind wheel and whole shaft type differential mechanism.In described whole shaft type differential mechanism, contain a front bevel type gear, bevel type gear after one, a left bevel type gear, a right bevel type gear, a differential housing, a differential shaft bearing, a main minor sprocket, a main hinge wheel, a main chain, a left minor sprocket, a left hinge wheel, a left chain, a right minor sprocket, a right hinge wheel, a right chain, a holoaxial, two holoaxial bearing supports, described front bevel type gear is arranged in differential housing front-side holes, and can in hole, freely rotate, described rear bevel type gear is arranged on after differential housing in side opening, and can in hole, freely rotate, described left bevel type gear is arranged in differential housing left hole, and can in hole, freely rotate, described right bevel type gear is arranged in the control of differential housing right side, and can in hole, freely rotate, described front bevel type gear, rear bevel type gear, left bevel type gear, interlock mutually between right bevel type gear, described main minor sprocket is arranged on the axle of motor, and there is nut to make it fixing, described motor is fixed on vehicle body, described main hinge wheel is arranged on left bevel type gear, be connected with differential casing through lasso with screw simultaneously, left bevel type gear and main hinge wheel are free to rotate, described main chain is arranged between main minor sprocket and main hinge wheel, described differential shaft bearing is enclosed within differential housing outside, between differential bearing sleeve and differential housing, bearing is housed, described differential shaft bearing is fixed on vehicle body, described left minor sprocket is installed on left bevel type gear, outside has nut to fix, described left hinge wheel is enclosed within on holoaxial, be connected with left rear wheel through axle sleeve with screw simultaneously, between left hinge wheel and holoaxial, can freely rotate, described left chain is arranged between left minor sprocket and left hinge wheel, described right minor sprocket is installed on right bevel type gear, outside has nut to fix, described right hinge wheel is enclosed within on holoaxial, between right hinge wheel and holoaxial, cannot freely rotate, described right chain is arranged between right minor sprocket and right hinge wheel, described left minor sprocket is identical with the diameter of right minor sprocket, described left hinge wheel is identical with right Dalian wheel diameter, the left end of described holoaxial is equipped with left rear wheel, between holoaxial and left rear wheel, bearing is housed, the left-external side of holoaxial is equipped with nut, described holoaxial right-hand member is equipped with off hind wheel, the right outside side of holoaxial is also equipped with nut, between holoaxial and off hind wheel, can not freely rotate, described holoaxial bearing support is contained on holoaxial, between holoaxial bearing support and holoaxial, bearing is housed, holoaxial bearing support is fixed on vehicle body.

Working principle of the present utility model is such: in the time that car is kept straight on, motor rotates by main minor sprocket, main hinge wheel, main large chain-driving differential housing, by left minor sprocket, left hinge wheel, left chain, drive left rear wheel rotate again, and another transmission approach is simultaneously; Drive off hind wheel to rotate by right minor sprocket, right hinge wheel, right sprocket wheel, rear axle, because left and right trailing wheel is stressed the same, left and right bevel type gear is not done relative movement, so two trailing wheel rotational velocity are the same, in the time that turn inside diameter for example turns left, left and right trailing wheel is stressed is different, this variation compressing makes left bevel type gear to counterclockwise rotating, force right bevel type gear to rotate to clockwise direction by front bevel type gear, rear bevel type gear again, the distance that consequently left rear wheel travels than off hind wheel is short, thereby reaches the object of differential.

The utility model has the advantages that: stressed even small volume, can also realize speed change by chain transmission.
