Abstract

The present invention relates to a dual-purpose motor vehicle for going upstairs and running on roads, every pair of wheels are composed of main wheels 2 and auxiliary wheels 7, a driving device is arranged among a dynamic device, the main wheels and the auxiliary wheels, for example, a dynamic gear 3 drives the auxiliary wheels 7 through a main gear 4 and a gear 5, and thus, the vehicle can run on level roads. The large resistance of the auxiliary wheels stops rotation when the vehicle meets a ridge, main wheels 1, the gear 4, the gear 5 and auxiliary wheels 6 are integrated, and the main wheels transmits under the drive of the gear 3 so as to drive the auxiliary wheels at the front upper part to run on the ridge. Then, the main wheels and the auxiliary wheels can rotate in a combined way to all run on the ridge completely. The present invention having the advantages of simple structure, convenient driving, stability and safety can be used for going upstairs and overbridges and running on roads.

Description

Go up terraced walking along the street dual-purpose motor vehicle

The present invention is a kind of ladder, walking along the street dual-purpose motor vehicle gone up, particularly a kind of manned loading, the step ladder self-propelled vehicle that can travel on level road again up and down.

Traditional stairs clambing handcart can only haul away by manpower, can not realize utilizing the power driven in the car.Though what have can still use crawler travel with the power driven in the car, or crawler belt and common wheel and usefulness, as the CN2286123Y that Patent Office of the People's Republic of China announces, it is huge that above-mentioned self-propelled vehicle upstairs exists health, heaviness, complex structure; During the transition on level road and ladder road, also to operate the jacking system of front and back wheel, so drive also loaded down with trivial details; And during by terraced upper mounting plate or by the platform descending stair, there is one to jolt.The purpose of this invention is to provide a kind of usefulness take turns again travel go up ladder, walking along the street dual-purpose motor vehicle, its simple in structure, convenient driving, and upper and lower building and transition highway section all steadily do not have the mountain peak and winnow with a dustpan.

Be to realize the purpose of foregoing invention, every pair of wheel set of self-propelled vehicle of the present invention comprises a swinging strut and four son wheels, and swinging strut can rotate on main shaft, and it has four arms of stretching out of isogonism towards periphery, and it is exactly that son is taken turns that the arm end has a wheel that can change.Power is passed to the wheel that an energy rotates earlier on main shaft, this wheel is sun gear, by sun gear power is passed to the son wheel and made the son wheel around consistent with turning to of sun gear from the rotation direction of axle, the group wheel can not be around when axle rotates because of being obstructed, Wheeling System just becomes the integral body that relative fixed is motionless, together under power do to be done with the sun gear unitary rotation.To sum up, car is on level road the time, and the resisting moment of son wheel is than little a lot of of the resisting moment of rotation support, so swinging strut does not change, the son wheel rotates, and car is travelled; When meeting bank, the stall of son wheel, swinging strut just is forced to rotate, the son of front upper place wheel is stepped to bank, swinging strut then, son wheel automatically according to the size of resisting moment in conjunction with rotation, all steadily go up to bank.

Sun gear together the transmission gear number in the middle of the shaft gear should be odd number, could guarantee like this that son is taken turns and mother take turns under dynamic action turn to identical.

After adopting such driving device, this car does not have heavy crawler belt, and power is passed to female wheel or son wheel as the case may be automatically by driving device.Make this car body long-pending little, simple in structure, fault rate is low, balance safety, easy to operate.

The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments:

Accompanying drawing is the exploded drawings of apparatus of the present invention.

Comprise in the accompanying drawing fixed main shaft 1, can the swinging strut 2 that rotates on the main shaft, power gear 3, the sun gear 4 that can on main shaft, rotate, transmission gear 5, with the coaxial gear 6 of the son coaxial siamesed of wheel, son wheel 7, vehicle body 8, operator platform and handrail 9, seat 10, wherein sun gear 4 is the bidentate wheel, one and power gear 3 interlocks, another and four transmission gear 5 interlocks, gear 6 and gear 5 interlocks, in the vehicle body 8 storage battery is arranged, high-speed motor and speed reduction gearing.

When switch closure, high-speed motor drives sun gear 4 by speed reduction gearing and power gear 3 and rotates on main shaft 1 all the time.On level road, gear 4 rotates simultaneously all four wheels by gear 5 driven gears 6, and wherein every secondary Wheeling System has that the son wheel lands on two, and car is travelled, this moment the son wheel resisting moment much smaller than the resisting moment of swinging strut, so swinging strut can not change; When meeting bank, the son wheel of front lower place is blocked, make its huge the increasing of resisting moment, can't rotate, son wheel changes motionless and causes that four transmission gears 5, four sub-wheels, swinging strut and sun gears 4 are all stiff to be one, is forced to whole together rotation, and is advanced in years to bank the son of former front upper place wheel, swinging strut, sub-wheel will all be gone up to bank reposefully according to the size of resisting moment in conjunction with rotation then.During following bank, swinging strut, son wheel under dynamic action in conjunction with rotation, reposefully down under bank.

The brake mode of this car: the motor speed in the car is very high, through 200 multi-fold decelerations power supply gear 4, so during the electrical motor outage, external force can not make gear 4 rotate, and gear 4 is when static, and the rotation direction of freely rotating of son wheel, swinging strut is just in time opposite, and both can only change or stop simultaneously simultaneously, as long as by the disconnected power down source of electric knob, car just can be parked in any position like this.

System is held in the support of this car direction: four pairs of wheels of this car, every pair of wheel are all by an independent motor drives, so turn as long as control stopping of which pair or two pairs of Wheeling Systems and change just passable by electric knob.

Above narration only is a most preferred embodiment of the present invention; what ought to explain is; those skilled in the art can make other all different structure modify fully according to the narration of specification sheets or part is replaced, and still, they must belong within connotation of the present invention and the scope of patent protection.

Claims

1. go up ladder, walking along the street dual-purpose motor vehicle for one kind, it comprises vehicle body, power system, brake system, control loop, wheel set; Its wheel set comprises main shaft (1), be installed in sun gear (4) on the main shaft (1), the swinging strut (2) by sun gear (4) driven rotary, intermediate drive gear (5), and four be positioned at the coaxial gear (6) of swinging strut (2) arm end, the coaxial mounted son wheel of shaft gear (6) (7) together; Drive power and pass to sun gear (4) on the main shaft (1), will pass to coaxial gear (6) through intermediate drive gear (5) by sun gear (4) again, coaxial gear (6) and coaxial mounted son wheel (7) rotation synchronously by power gear (3); When the last ladder of group wheel (7) was subjected to resistance, whole Wheeling System rotated around main shaft (1) relative to whole with one, thereby crosses stairway step.
