JPH09183362A - Point turn system for automobile - Google Patents

Abstract

PROBLEM TO BE SOLVED: To easily carry out a direct switch, parking in a vertical line, a cut of a steering wheel of an automobile, which require a lot of space, labor, and technique, by only two operations (a lift operation and a rotating operation) of a point turn system by even a beginner driver and to facilitate jacking up of an automobile. SOLUTION: A power linkage, which is hydraulically operated, is arranged in the center gravity position of an automobile, a power cylinder 2 is arranged on a vehicle body side while a structure constructed by integrally welding a power piston 3, a power piston rod 4, a wide disk type foot 5, a circularly bored drive plate 7 to which a ring gear 8 is shrinkage fitted, and a cylinder 6 is arranged on the ground side, and a reduction starter 10 for clockwise rotation and a reduction starter 11 for counterclockwise rotation, by which a pinion 9 can jump into the ring gear 8 when the automobile is lifted to the uppermost position, are provided on the vehicle body side.

Description

Detailed Description of the Invention

The present invention is characterized in that it is possible to turn in any direction at a minimum turning radius of 0 m while driving an automobile, which makes it very convenient for both beginners and veterans depending on how it is used. Also, by lifting the car near the center of gravity and widening the foot area as much as possible, it can be used as a stable hydraulic jack instead of tire replacement,
It is a system that makes light maintenance such as tire and chain hanging easier.

Conventionally, the turn of an automobile is based on the turning theory of Ackermann-Junt, and is turned with a considerable turning radius even though there are some applications such as 4WS.
It took a lot of roadway to get there. Until now, it was impossible to turn points on the spot except for caterpillar cars.

The present invention is a system capable of turning a vehicle on a small road width and easily jacking up a car. Toral) and P
To (Power Take Off) ON or P / S
(Power steering) When switching the oil passage from the oil pump and pushing on the operation panel 14 inside the vehicle, the oil enters the chamber A of the power cylinder 2 and the oil in the chamber B operates. The power piston 3 lowers, so that the power piston rod 4, foot 5,
When the cylinder 6, the drive plate 7 and the ring gear 8 come down as a unit and the foot 5 hits the ground, the reaction causes the car to lift. Next, after the car has completely reached the highest position (the wheels are slightly raised), the operation panel 14
When the right or left of is pressed, the pinion 9 of the reduction starter 10 or 11 for it jumps into the ring gear 8 and becomes ON and vigorously starts turning in that direction with high torque. At that time, the guide 12 surrounds and guides the cylindrical shape 6 and that the foot 5 is a wide flat disk,
Cover some weight imbalance. When you have reached the desired position, press and hold the bottom of the control panel 14 and the car will touch down again and the foot 5 will return to its original position. Even if an unstable situation occurs and the vehicle tilts, the level 13 allows the instability to be observed objectively. If you press the bottom of the operation panel 14 immediately, Cars that were lifted and unstable began to fall and soon regained stability. In such a case, change the ground on which the foot 5 is applied or change the weight balance of the car and try again.

In this way, if the vehicle has a small space, point turning becomes possible, and the driver does not have to switch back and forth repeatedly. It is possible to turn in any direction. Further, since the automobile can be jacked up by hydraulic pressure, light maintenance such as tire replacement, tire rotation, and tire chain hanging can be easily performed, which is also effective in terms of maintenance.

In the unlikely event that this system has the most piston rods, that is, even if the motor rotation switch is turned to the right before the car has risen to the maximum, it will be left to the left.
Even if it is N, the pinion just jumps out and spins idle,
The car does not try to point turn because it does not get caught in the ring gear, which prevents the starter from being overheated by a heavy load. Also, even if the upper or lower part of the operation panel is pushed more than necessary, troubles such as cylinders due to the rise of hydraulic pressure can be avoided if the safety check valve is used.

It should be noted that the legs returning to the original position while driving also serve as the under guard of the automobile.

Claims (1)

[Claims] 1. A power piston is hydraulically moved from one power cylinder in the vicinity of the center of gravity of a vehicle, and a piston rod with a foot attached to the piston descends, and when it hits the ground, it is a reaction. A drive that lifts the car and has a ring gear on the outer periphery of the upper end of a cylindrical shape (like a cylinder liner) that is integral with the piston rod with feet, and a circular hollow inside.
Using a reduction starter from the body (body) side of the welded plate, engage the pinion with the ring gear described above and turn the motor, so that the vehicle is on the spot. A system that can turn in any direction.
