The equal moment motor differential mechanism has the structure that a motor stator and a motor rotor are respectively installed on a carriage axle and a hub, and in four conical gears which are meshed with each other in right-angle, a pair of conical gears with the same coaxial line are respectively and coaxially fixed on the left and the right axles. Due to the special structure of the motor differential mechanism, the two trailing wheels of a light type solar powered car can be ensured to have the equal moment no matter the solar powered car is driven by a single wheel or double wheels, thereby guaranteeing the stability of the light type solar powered car when running in high speed.
Description
Technical field
The utility model relates to torque motor difies such as a kind of light-weight solar automobile, belongs to the apparatus of transport technical field.
Background technology
The practicability solar automobile is by solar panel power supply, motor-driven.Existing low speed battery-driven car does not all have diff, if be that the type of drive of one is used for solar automobile with this battery-driven car wheel and motor, can have following shortcoming: (1) trailing wheel is a two-wheeled, wherein one when having taken turns motor, constitute single wheel drive, on one side can cause drive torque to have, Yi Bian do not have; (2) trailing wheel is a two-wheeled, when two-wheeled all has motor, constitutes two-wheel and drives, though very big improvement is arranged, can cause the drive torque can not be identical.The overbalance of moment, the instability in the time of can causing the vehicle body high-speed motion, thereby be necessary to select a kind of device, make two trailing wheels have dynamic constant force square and drive, the stability during with assurance solar automobile high-speed motion.
Summary of the invention
Technical problem to be solved in the utility model provides torque motor difies such as a kind of light-weight solar automobile, can overcome the shortcoming that existing electricity drives the car moment unbalance, make two trailing wheels have dynamic constant force square and drive the stability when guaranteeing the light-weight solar automobile high-speed motion.
Solving the technical scheme that technical matters of the present utility model adopts is: motor stator and rotor are installed in respectively on axletree and the wheel hub, in four meet at right angles intermeshing bevel gear, there is the bevel gear of a pair of coaxial line coaxial fixing with left and right axletree respectively.Four bevel gears are installed in the diff shell, and the diff shell is connected in shock absorber again and connects to ground.One sidecar axle connects shock absorber by the diff shell, and the opposite side axletree is the direct connection shock absorber then, and two shock absorbers axially being symmetrical arranged at axletree.
During electrical power work, the intermeshing bevel gear diff owing to packed into, thereby exist relative motion between rotor and the motor stator, therefore no matter adopt single motor-driven or Dual-motors Driving, by the sense of motion transmission between the bevel gear, the single wheel that links to each other with bevel gear has had equidirectional and big or small rotating speed and moment with the opposite side wheel that links to each other with rotor.
The beneficial effects of the utility model are: guarantee that two wheels such as are in all the time at the moment state, overcome the shortcoming that existing wheel and motor are the moment unbalance that type of drive caused of one, provide a kind of moment compensator of similar differential design, make two trailing wheels have dynamic constant force square and drive the stability when having guaranteed the light-weight solar automobile high-speed motion.This differential design is simple, is convenient to maintenance.
Description of drawings
Fig. 1 looks generalized section for the utility model master,
Fig. 2 is the utility model scheme of installation.
Each label is represented successively in Fig. 1～2: 1, shock absorber, 2, motor stator, 3, rotor, 4, the diff shell, 5, axletree, 6, bearing, 7, bevel gear one, 8, bevel gear two, 9, bevel gear three, 10, bevel gear four, 11, axletree.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Embodiment 1: single motor-driven situation
Referring to Fig. 1,2, during the solar automobile motion, the situation of prior art is that axle tree 5 the wheel does not here have drive motor, and axletree 11 the wheel here has drive motor, and then axletree 5 is fixing, and the rotor 3 that links to each other with wheel rotates, monolateral driving solar automobile advances, and moment is non-equilibrium state.After the diff, axletree 5 is no longer fixing if pack into, and rotor 3 and motor stator 2 exist relative motion.In addition, because application force equals antagonistic force, thereby rotor 3 and motor stator 2 have the moment that direction is opposite, size is identical.The rotor 3 that links to each other with wheel nave rotates car is travelled forward, and rotating speed is n.There is reverse motions in motor stator 2, and application force equals antagonistic force.Because moment is identical, direction is opposite, with respect to static frame of reference, if two resisting moments that wheel overcame are identical, then the rotating speed of stator is-n, shown in the small arrow among Fig. 1, bevel gear 10 counter-rotatings, rotating speed is-n, transmission by bevel gear 7 and bevel gear 9, when passing to bevel gear 8 at last, the rotating speed of bevel gear 8 is opposite with bevel gear 10, and rotating speed is n, identical with rotor 3 rotating speeds, and the direction unanimity.Like this, the left side wheel that links to each other with bevel gear 8 has equidirectional and big or small rotating speed and moment with the right wheel that links to each other with rotor 3.Here be noted that the relative rotation speed between the rotating speed-n of the rotation speed n of rotor and motor stator is 2n, i.e. fixed electrical machinery stator, the rotating speed of wheel is 2n, if adopt single motor-driven, then speed only is original half.Motor deceleration device is removed in suggestion, or adopts high-speed electric expreess locomotive.
Embodiment 2: the situation of Dual-motors Driving
For double-motor, situation and single electric machinery are seemingly.Two rotors that link to each other with wheel 3 rotate car are travelled forward, and rotating speed is n.There is reverse motions in two motor stators 2, because two stators link to each other by diff, two ends axletree 5 and 11 sense of motion are opposite, if two powers of motor are identical, the moment that provides is also identical, trailing wheel two ends axletree 5 is opposite with 11 sense of motions so, and positive and negative moment offsets, final trailing wheel two axletrees 5 and 11 no relative motions.If motor there are differences, then there is relative motion in these two axletrees 5 and 11, make moments such as axletree 5 and 11 maintenances.The existence of diff makes the advantage of moments such as two drive wheels have, and two-wheeled can have different rotating speeds to exist.For Dual-motors Driving, if the relative rotation speed between two motor stators is zero, i.e. fixed electrical machinery stator, the rotating speed of wheel is the normal speed of motor.
