Description
Technical field
The utility model relates to differential mechanism, particularly relates to ride instead of walk drive unit on the car of handicapped people's power, more specifically relates to a kind of chain-drive differential mechanism.
Background technique
Automobile-used differential mechanism is the critical piece in the motor vehicle drive system, it is mainly used in and drives the driving wheel rotation, automobile-used differential mechanism is generally driven by axle, its differential mechanism mainly is made up of planetary pinion, semiaxis, shell, actuation gear etc., in handicapped people's power is ridden car instead of walk, the power of motor or motor directly drives the rear axle rotation of car by chain, rear axle drives the trailing wheel rotation, its driving mode exists radius of turn big, obstacle detouring hinders a little less than the ability, use defectives such as inconvenience, can not satisfy disabled human needs.Therefore, ride instead of walk the drive unit of car of handicapped people's power that haves much room for improvement.
Summary of the invention
The purpose of this utility model: for satisfying disabled human needs, improve handicapped people's power drive unit of car of riding instead of walk, and a kind of chain-drive differential mechanism is provided.
The technical solution of the utility model is achieved in that a kind of chain-drive differential mechanism, middle part at main shaft has planetary plate movingly, on planetary plate, be provided with planet wheel, the axis of planet wheel and the axes intersect of main shaft and vertical, be provided with the planetary plate sprocket wheel at the planetary plate outer fixing, on main shaft, the both sides that are positioned at planetary plate respectively are provided with a planet side gear successively, countershaft, input and output gear, the planet side gear is movingly on main shaft, side tooth on the planet side gear and planetary pinion engagement, countershaft is fixed on the main shaft, the axis of countershaft and the axes intersect of main shaft and vertical, on the bearing support at the two ends of countershaft, respectively be connected with a countershaft duplex tooth, the gearwheel of countershaft duplex tooth is meshed with the axial tooth of planet side gear, and the small gear of countershaft duplex tooth is meshed with the gearwheel of input and output gear, is provided with input sprocket on input and output gear, output sprocket.
On described main shaft, be provided with locking nut, in order to limit the axial position of planet side gear, input and output gear.
Described planetary plate sprocket wheel is meshed with the chain that main motor drives, and input sprocket is meshed with the chain that auxiliary motor drives, and output sprocket is meshed with the chain of driving wheel.
Working principle of the present utility model: chain drive differential mechanism of the present utility model is installed in handicapped people's power and rides instead of walk when keeping straight on the car, main motor drives the planetary plate rotation by chain, the planet wheel not rotation of revolving round the sun at this moment, planet wheel drives planet side gear, countershaft duplex tooth, input and output gear, the main axis rotation on both sides successively, the output sprocket of rotation is by ride instead of walk the driving wheel rotation of car of chain drive handicapped people power, both sides indifferential.When chain drive differential mechanism of the present utility model is ridden the car turning instead of walk at handicapped people's power, be example as turning left, when, left side resistance increases, be that left side input and output gear is when being in semi-brake or full application of brake, left side input and output gear is in slow-speed or does not change, planetary plate this moment rotating speed under the drive of main motor is constant, the planet side gear on the right is in normal rotation, at this moment, the right input and output gear is faster than the rotation of left side input and output gear, and the right input and output gear and left side input and output gear are realized differential, makes the handicapped people be with the step power car to turn left.In like manner, when the right input and output gear resistance increases, handicapped people's power car of riding instead of walk is bent to right.When main motor stops to drive, start auxiliary motor, auxiliary motor drives input and output gear rotation on one side, makes handicapped people's power car of riding instead of walk realize the rotation of minor radius on the spot; When auxiliary motor drives the incorgruous rotation of input and output gear on both sides, handicapped people's power car original place of riding instead of walk is rotated.
The beneficial effects of the utility model: chain drive differential mechanism of the present utility model, simple in structure, easy to use, can make ride instead of walk the car original place rotation of handicapped people's power, obstacle detouring hinders ability strong, is particularly suitable for handicapped people's power differential mechanism that car drives of riding instead of walk.
