An electric motor includes a chassis having a front tube to rotatably support a handle, two arms each having one end pivotally attached to the chassis to support two front wheels on the outer ends. A cushioning device may be used to cushion the front wheels and the arms relative to the chassis. A carrier is pivotally attached to the rear portion of the chassis, and includes a spindle to support two rear wheels. An electric motor device is attached to the carrier to drive the rear wheels. Another cushioning device may be used to cushion the rear wheels and the carrier relative to the chassis.

An extension apparatus of a seamless bridge comprises a half-beam (1) and a chain (2). A remote beam end of the chain (2) is connected to a remote beam end of the opposite half-beam (1). The chain (2) is supported by means of a groove on a side surface of an adjacent half-beam (1), and is bent and extended when a bridge is bent and extended. An upper surface of the chain (2) is approximately parallel and level to a surface of the bridge. The extension apparatus of the seamless bridge can fill a pit between half-beams as the bridge is bent and extended, and reduce vibration of a vehicle.

The invention discloses a dual-purpose openable-closeable-topped two-wheeled saloon car steered through a push-pull rod. The dual-purpose openable-closeable-topped two-wheeled saloon car steered through the push-pull rod comprises an original car body, a front wheel, a rear wheel, a brake device and a main motor. A car cover for a user to get on or off is installed at the upper portion of the car body. A dual-purpose openable-closeable-topped car roof cover is installed at the upper portion of the car cover. A steering push-pull rod device installed on a front wheel steering handle is high in freedom degree, the user can comfortably drive the car on the ground or by at a high or low position and control running steering, car speed and braking. Supporting wheels are installed on two sides of the car, a driver in the car operates the supporting wheels to be in contact with the ground or lift the supporting wheels so as to perform car supporting or parking through a foot-controlled foot pedal, the supporting wheels are in contact with the ground to lock the three-wheeled running car and are wind-resistant, and the car speed is the same as the speed of the saloon car when the three-wheeled running car is lifted by the supporting wheels. During emergency braking, safety supporting feet on two sides of a car head and the supporting wheels can be propped up to the ground to achieve safe parking in a four-foot mode. A single-seat saloon car and a saloon car for two and a half (child) are provided. The low car body of the saloon car is 1.18 meters, the wide supporting wheel distance is 1.10 meters, and the saloon car is small in wind resistance, safe in running and capable of saving energy, reducing haze and relieving traffic jam and can be driven on the road after a certificate is issued.

Provided is a shift control device for vehicles for minimizing the prolongation of the required time from the time when the driver performs an operation to enable the vehicle to travel to the time when the vehicle comes to a travel possible state. A switch position update permission means (136) permits update of the switch position information stored in a switch position information storage device (116) on condition that a wall position detection control means (132) performs switch position recognition control. When a P-ECU (shift control device) (106) is switched from a nonactuated state to an actuated state, a switch position update means (134) updates the switch position information stored in the switch position information storage device (116) after the switch position update means (134) is permitted to update the switch position information by the switch position update permission means (136). Therefore, since the occasions the switch position information stored in the switch position information storage device (116) is updated assuming the switch position information is indefinite decrease, the prolongation of the required time can be minimized when the operation to enable the travel is performed after the P-ECU (106) is turned on next time.
