Description

The superminiature sedan-type cycle

The utility model relates to a kind of superminiature sedan-type cycle.

Since 1987, the domestic 60 multinomial quadricycle patents that disclose altogether, for bicycle, quadricycle has ride comfort, it is stable to ride, advantage such as safe and reliable, but because these patents have adopted the shedding cam circumference formula of similar bicycle to drive aspect actuating device mostly, this type of drive takes up room greatly, and in configuration aspects, almost existing quadricycle has all adopted front-wheel steering, the mode of back-wheel drive, actuating device is installed between two front-wheels, because steering hardware and actuating device are installed in body forward structure simultaneously, cause body width to be difficult to dwindle, this structural defective has increased the area that lands of full car inevitably.In traffic crowded day by day today, it is the problem of a key that car body lands area, and Here it is, and existing quadricycle patent is difficult to promote in town and country, does not obtain developing the major reason with the market approval so far.

The purpose of this programme is to invent the length of a kind of fusion bicycle and four-wheeled, the area of can promoting in the city, land only is equivalent to a bicycle, actuating device is simple, takes safety and comfort, and convenient driving also has the superminiature sedan-type cycle of similar automobile partial function.

For achieving the above object, the utility model is made up of vehicle body, front and back each two wheels, steering hardware, actuating device, brake equipments, steering hardware is made up of interior axle, pipe link, turning wire rope, steering track rod, the spindle arm of bearing circle, bearing circle, and actuating device is made up of pedal, connecting arm, ratchet, axle drive shaft, speed change drive sprocket set, speed change driven chain wheels, diff.The interior axle of bearing circle that is located at vehicle body operator's compartment front end is captiveed joint by governing screw with pipe link, pipe link and vehicle body are hinged, the spindle arm and the steering track rod of captiveing joint with half-rear axle are hinged, steering track rod is connected by turning wire rope with pipe link, turning wire rope penetrates two ends and is fixed in the flexible pipe on the vehicle body, makes it can carry out flexible transmission in flexible pipe; The axle drive shaft that is installed in body structure is equipped with speed change drive sprocket set, two ratchets, left and right sides pedal is hinged with the connecting arm that is fixed on the two ratchet outer rings respectively, the driven shaft that is located at vehicle body middle part is provided with speed change driven chain wheels, is connected for chain between the hinge wheel between speed change drive sprocket set and the speed change driven chain wheels, on the driven shaft and the diff.

For dwindle body width as far as possible, this car has adopted the mode of f-w-d, rear-axle steering, and actuating device is installed between two front-wheels, and diff is installed on the front axle, bearing circle is by pipe link, turning wire rope, and pulling left and right sides spindle arm drives half-rear axle and controls turning to of two trailing wheels.

For make ride smooth and easy, the utility model also is provided with synchronous device, synchronous device is made up of left and right sides lever and pull back spring, left and right sides lever is installed in the inboard of two ratchets on the axle drive shaft, the two ends of lever respectively have one to protrude the position, two levers are in same plane and for captive joint, left and right sides connecting arm and lever have all been installed pull back spring, and pull back spring and vehicle body are for captiveing joint.

Another improvement project of the present utility model is: actuating device is provided with boost installation, boost installation by the speedup main shaft be contained in it above big gear wheel, ratchet, speedup rocking bar, the tween drive shaft of captiveing joint with the ratchet outer ring, be installed in intermediate gear and the intermediate chain wheel on the tween drive shaft, the speedup ratchet that is located on the diff is formed, big gear wheel is meshed with intermediate gear, is connected for chain between intermediate chain wheel and the speedup ratchet.

For making the utility model have more the small passenger car feature, as shown in Figure 1, 2, its outward appearance has adopted airflow design, body top section adopts transparent material, body bottom section adopts PVC engineering plastics or other chemical materials, the body bottom section upper end is provided with groove, makes body top section move forward and to take out along groove, so that the personnel of driving get on or off the bus and keep in repair.
