Abstract

PURPOSE:To decelerate or stop a vehicle safely and quickly by bringing an object into contact with the road surface during the running of the vehicle. CONSTITUTION:When a vehicle is to be decelerated or stopped with a foot brake, the portion 2 of a ground brake interlockingly fitted below a vehicle is first brought into soft contact with the road surface 1, then pressure is gradually applied between the portion 2 and the road surface 1. Friction resistance is remarkably increased as compared with the conventional system using only wheels, and the vehicle can be stopped in a shorter braking distance as a result.

Description

[Detailed Description of the Invention] Conventionally, in order to stop an object running on a road surface (hereinafter referred to as a vehicle) using the power of an installed engine, the rotation of the wheels driving the object is stopped, and then the wheels and the road surface are connected. Vehicles have been stopped and decelerated by the frictional resistance between them.

However, the number and size of wheels increases mainly depending on the weight of the car, and as a result, the contact surface increases.
This has simply led to an increase in frictional resistance and caused the vehicle to stop.

The present invention uses something other than these wheels that comes into contact with the road surface (hereinafter referred to as "ground brake") when decelerating or stopping, and the part (2) of the ground brake that comes into contact with the ground and the road surface (1)
) is used to increase the frictional resistance between the vehicle and the vehicle to decelerate and stop the vehicle.

The structure of the present invention is such that when a foot brake or the like is used to decelerate to a stop, the part (2) of the ground brake attached to the lower part of the vehicle first makes soft contact with the road surface (1) and gradually applies pressure. is the structure added between this (2) and the road surface (1).

As a result, the frictional resistance increases dramatically compared to the conventional system using only wheels, and as a result, it is possible to stop the vehicle with a shorter moving distance. The shape of the ground brake is
It can be circular like a wheel, inside a rail, flat plate, or anything else you like, but in the case of ground brakes made of the same material, the larger the part (2) in contact with the ground, the more effective it is for short-distance braking. It is true. Also, the part that comes into contact with the ground (2
) is more effective when using a material with a large coefficient of friction.

Spiked tires have traditionally been used when driving on snowy roads, but some local governments are considering banning their use due to the dust that is generated during braking. Therefore, although studless tires have been developed, the side effect is not necessarily sufficient for safe stopping. By making the present invention into a shape as shown in Fig. 2, it is effective even in the case of braking on snowy roads. .
