In this vehicular chassis system, the vehicle's passenger compartment and wheels incline toward the turning center side in such a manner, that the wheels can be tilted independently from steering. This vehicle has a steering apparatus controlling the steering, and a separate apparatus controlling the lateral leaning. The lean is controlled mechanically using a pendulum, and forced lateral leaned using a control unit, or manually with the transfer of body weight using several pinions with a set ratio to control the passenger compartment lateral lean in conjunction with the wheel lateral lean.An electric DC servo gear motor can be used to control the lateral lean, that in turn moves a pinion, which moves a rack and lateral movable cross member, while controlling the lateral leaning wheels and pulling the tilt support bar pivotally attached to a passenger compartment in the same leaning direction.

A three-wheel pedal-style wheelchair which includes a roller at a side, close to the ground, of the wheelchair, wherein the roller prevents the wheelchair from turning over, a steering wheel arranged at a side of the wheelchair, and two front wheels respectively arranged at two opposite sides of the wheelchair, wherein the two front wheels comprises a driving wheel led to rotate forward or backward by a user stepping and a loose wheel, wherein when the wheelchair turns to a direction in a small radius, the steering wheel is considerably rotated to a direction and the driving wheel is rotated forward, wherein when the wheelchair turns to another direction, the steering wheel is considerably rotated to a direction and the driving wheel is rotated backward. Accordingly, the wheelchair is easily controlled to have a small turn, like whirling in one spot, to move and to turn safely.

A three wheeled vehicle that has an improved dual front wheel integrated steering and suspension system that allows the vehicle to be maneuvered by a combination of arm and leg steering movements coupled with front end leaning that shifts the center of mass of the vehicle down and toward the inside wheel. This transfer of mass counteracts a conventional cornering vehicle's tendency to fling its mass to the outside wheel and lift the inner wheel off the ground as well as changing the angle of the line of force exerted through the tires, and enhancing the vehicles's grip on the ground. The vehicle has a reduced amount of sliding and potential of flipping when turning sharply. The steering system is compatible with traditional ACKERMAN steering geometry wherein the inner wheel turns in a smaller diameter circle than the outer wheel.

The invention discloses a thermos cup. The thermos cup comprises a cup body, cup covers and a drinking base, wherein the cup covers comprise an upper cover and a lower cover; the lower cover is fixedly arranged on the cup body; the upper cover is arranged on the lower cover in a folding manner; the rear end of the upper cover is rotationally connected with the rear end of the lower cover. The thermos cup is characterized in that the drinking base is detachably arranged in the lower cover in a thread matching manner; a mounting groove is formed in the rear side of the drinking base; a safety button which can be vertically move is arranged in the mounting groove; a buckle is convexly arranged below the rear side of the safety button; an opening for allowing the buckle to extend out is formed below the rear side of the mounting groove; an elastic part by which the safety button always faces upwards and is matched and locked with a clamping part of the lower cover is arranged between the bottom of the safety button and the mounting groove. The thermos cup disclosed by the invention is reasonable in structure, is good in insulating property and is safe and reliable in use, and can be produced into various insulating containers such as sports kettles and bachelor cups; the cup covers and the drinking base respectively adopt a two-section opening form.

The invention relates to a power-assisted steering system special for an electric automobile. The power-assisted steering system comprises a steering wheel, wherein the steering wheel is connected with a steering gear through a steering shaft, the steering gear is connected with front wheels through a connection rod mechanism, and a torque sensor is arranged on the steering shaft and connected with a controller through a data line. A motor is arranged on an automobile chassis and connected with a clutch, the clutch is connected with a speed reducer, an output shaft of the speed reducer is connected with the steering shaft, an angle sensor is arranged on an output shaft of the motor and connected with the controller through a data line, the controller is connected with the motor through the data line, the motor is connected with an electric automobile battery pack through a battery pack wire, and a speed sensor of the automobile is connected with the controller through a data line. The power-assisted steering system is driven by the motor and provided with the controller, and the controller detects speed signals and steering wheel rotating shaft torque signals in the driving process of the electric automobile and controls output torque, rotating angles and rotating directions of the motor through the signals so as to lead the motor to drive the front wheels of the automobile to steer.

The invention relates to a safe position-limiting mechanism for an automatic rotary table conveying device. The safe position-limiting mechanism for the automatic rotary table conveying device comprises a stopper arranged on a rotary table roller way, and a pressing plate arranged on a conveying roller way, wherein the stopper comprises two sleeves arranged on a bottom plate of the rotary table roller way; support rods are inserted into the two sleeves; one ends of the two support rods are connected with the bottom plate of the rotary table roller way through springs; the other ends of the twosupport rods are connected with the bottom part of one long strip-shaped stopper block; the top part of the stopper block is located above the rotary table roller way so as to stop a workpiece; the bottom part of the stopper block is connected with one end of a connecting rod; a rolling wheel seat and a rolling wheel are arranged at the other end, penetrating through the bottom plate of the rotary table roller way, of the connecting rod; two sections of inclined surfaces with opposite inclined directions are arranged at the bottom end of the pressing plate; the pressing plate is located on arotation path of the rolling wheel rotating along with the rotary table roller way, so that the rolling wheel contacts one section of the two sections of inclined surfaces and rolls along the inclinedsurface so as to drive the stopper block to move downwards, and the top part of the stopper block is located under the rotary table roller way; and through the elastic acting forces of the springs, the stopper block is reset after the rolling wheel and the pressing plate are separated.
