The invention relates to an asphalt road surface material which is applicable to crossroads and bus station platforms in severe cold regions, aiming to solve the problem that the asphalt road surfaces on the bus station platforms which buses drive into frequently and on the side of stop line at crossroads with larger traffic flows in large cities in northern severe cold regions are rugged due to frequent braking. In the invention, the mass of rubber modified asphalt accounts for 9.6-10.3% of the total mass of aggregate and filler, the mass of iron ore tailing sands accounts for 2.8-4.2% of the total aggregate mass, the grain diameters of basalt are 5-8mm and 14-17mm. The inventive asphalt road surface material can not have upheavals or tracks in summer even under the condition of frequent braking, or crack in winter, thus being especially suitable for frequent braking positions at bus station platforms, crossroads with larger traffic flows, slope base of descending sections in cities in severe cold regions.

A method and a system for controlling a parking brake of a motor vehicle are described. According to the described method, an ignition signal and an actuation state of the parking brake are detected. An application force of the parking brake is then set to a first value in dependence upon the actuation state of the parking brake if the ignition signal is present. If the parking brake was previously in an applied actuation state, the application force is reduced from a second value to the first value. If the parking brake was previously in a released actuation state, the application force is increased to the first value. The first value is sufficient to hold the motor vehicle in its current position.

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.

The present invention relates to a vehicle for a magnetic levitation track having a coach body (1) and a propulsion and supporting device (4) as well as at least one levitation frame (2) fastened on the coach body (1) and the propulsion and supporting device (4). The levitation frame (2) can be deflected transversely to the longitudinal axis of the propulsion and supporting device (4) and a spring suspension system (12, 14, 20, 21) is arranged between the levitation frame (2) and propulsion and supporting device (4). The levitation frame (2) has a traverse (13) and a carrier (17) which are connected to each other in an articulated fashion.

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.

The invention discloses a roadbed construction technology suitable for saline soil areas. The roadbed construction technology comprises the following steps of salt content detection of the original ground, filler type selecting, filler field testing, material covering processing, pre-roadbed-filling treatment, layered filler paving, filler compaction, separation layer laying and roadbed water problem treatment. A roadbed with the low construction cost and capable of reducing incidence of common diseases such as salt expansion, freezing expansion and melt sinking during application period is provided, integrity of road structure and comfort and security of vehicle driving are guaranteed, and application and maintenance costs are lowered.
