In the emergency brake assist device of the present invention, a motor, a hydraulic cylinder, a pneumatic cylinder, or an electromagnetic solenoid can be used as the power source indicated by the power transmission mechanism. The power is transmitted to the bearing end of the support portion of the brake mechanism by the transmission member, whereby the brake plate attached to the bottom end of the support portion can perform up and down operations.

In the present invention, a hydraulic (pneumatic) cylinder for cushion is provided between the support portion of the brake mechanism and the brake plate to enhance the stability of the vehicle body during emergency braking. Further, a compression spring structure is formed at the mounting portion of the support portion, and a stable frictional force is maintained between the brake plate and the road surface.

And a braking plate 11 made of a copper plate. The top surface is fixed to the bottom end of the support 10, and the brake plate 13 is mounted on the bottom surface of the brake plate 11. The brake plate 13 is formed of a material that does not break the asphalt road surface made of rubber or other synthetic fibers equivalent to that of a tire and can exert a friction braking effect. The power transmission mechanism includes a motor power source 20, an output shaft 21 of the motor, and a gear set transmission member 22 provided between a bearing end of the support 10 and the power transmission mechanism. The starter has a switch 30. The switch 30 connects the battery 31 and the motor power source 20 by an electric wire 32 and is provided at an appropriate place in a driver's seat. In the above-described apparatus, the motor power source 20 is started by the switch 30 at the same time when the brake is applied, and the gear train transmission member 22 drives the support portion 10 to quickly lower the brake plate 11 at the other end of the bearing. Friction occurs between the brake plate 13 and the ground, thereby greatly reducing the running inertia of the vehicle and producing a brake assist effect other than the wheels on the vehicle.

As shown in FIGS. 1 and 2, in the emergency brake assist device according to the embodiment of the present invention, the brake plate 11 attached to the bottom end of the support portion 10 has different The shape of the plate can be changed appropriately. For example, when the brake plate 13 on the bottom of the plate is formed of a nail plate 14 or a copper plate 15 having other uneven patterns, the brake plate 13 is applied to an auxiliary brake on an industrial road or a snowy area where asphalt is not laid in mountainous areas.

As shown in FIGS. 4 and 5, the power source of the power transmission mechanism of the emergency brake assist device according to the present embodiment may be a general hydraulic (pneumatic) cylinder 40 or an electromagnetic solenoid 50. The support portion for connecting the brake plate 11 of the brake mechanism is formed by combining two support portions 41 and 42 into one set, and one end of the two support portions 41 and 42 is concentric with the brake plate 11. The other end is pivotally connected to a hydraulic (pneumatic) cylinder 40 and a fixed base 43, respectively. When the cylinder shaft 40 is pushed out, the two support portions 41 and 42 come into contact with each other in an interlocked manner, whereby the brake assisting effect provided by the present embodiment can be exhibited.

In the emergency brake assist device according to the present embodiment, the switch 30 of the starting device is provided to the driver to independently control the starting power of the power source, and its basic structure is a battery. A changeover switch by communication between a power source and a general road is also possible. As shown in FIG. 6, the structure of the brake assist device according to the present embodiment is different from that of FIG. The base 16 is extended to be integrally connected to the pivot of the support 10. It is possible to pivot the main body and cylinder axis of the hydraulic (pneumatic) cylinder for cushion 60 on the support portion 10 and the base 16 of the brake plate, respectively. It is possible to hold the pressing force.

As shown in FIG. 7, in the brake assisting device according to the present embodiment, a supporting portion 41 and a supporting portion 42 are pivotally mounted on a base 16 extending to a top surface of a brake plate, and a compression spring A shaft column 162 to which 163 is attached is provided. The brake plate 11 can maintain a stable pressure and presses the road surface firmly as the wheels are moved up and down. In the emergency brake assist device according to the present embodiment, the switch 30 of the starting device is provided for the driver to independently operate and control the starting power of the power source.
