Description

[Detailed description of the invention] Industrial applications The present invention relates to a brake device for a vehicle.

Conventional technology and its problems As a service brake, the so-called foot brake, in which the pedal is pressed with the tip of the foot, has been widely used.
This is common knowledge in automobiles.

Generally, when applying sudden brakes, the pattern from sensing danger until the vehicle comes to a stop involves perception, judgment, action, and action. Normally, the handbrake is applied slowly and is located in a position that is not suitable for instantaneous operation.

Additionally, some people may mistakenly press the accelerator pedal when they should have pressed the foot brake pedal, and there have also been cases where the driver simply gripped the steering wheel and did not press the foot brake pedal enough, causing the vehicle to come to a different parking position and cause an accident.

However, when stopping the vehicle, it is possible to use both hands or one hand in addition to the feet to perform manual operations other than gripping the steering wheel. That is, the brake near the steering wheel or steering column and the conventional foot plate kit.
It is possible to use them together. The present invention is particularly characterized in that it also has a manually operated brake function.

OBJECTS OF THE INVENTION Brake performance is one of the most important aspects of accident prevention performance for vehicle structures such as automobiles. The present invention
The braking performance is improved by providing a manually operated second brake that can be operated in conjunction with or independently of the conventional foot brake.

DESCRIPTION OF THE INVENTION The present invention is a device in which a manually operated brake can be operated near the steering wheel or near the steering column.

That is, the final transmission portion to be transmitted by the manual operation is the portion up to the hook-shaped protrusion for moving the receiving portion provided on the brake shaft, and the brake shaft is connected to the 7-piece brake and the manual brake. As a common part, the structure is such that both operations can be performed simultaneously or separately without affecting each other.

Embodiments The embodiments shown in A-B-C below are shown in the figures as a means of transmission to a movable protrusion for moving a receiving part provided on a brake shaft by manual operation near the steering wheel or steering column. I will explain based on this.

(In the case of the 1-A system, Fig. 1--here, 1 is a brake wheel.1 This wheel 1 is formed integrally with the brake column 2, and the transfer column 2 is a steering wheel located at the outer periphery of a concentric axis with the steering shaft 6. The brake column 2 is installed in a column 4 and is mounted between a steering shaft 3 and a steering column 4 so that it can freely rotate and move back and forth, and is supported by, for example, a bearing 5 and a spring 6.

On the other hand, at the tip of the brake column 2 opposite to the wheel 1gB, an intermediate connecting body 8 is rotatable about the column 2 as an axis and movable along the longitudinal groove 7 of the steering column 4.
The connecting body 8 is connected to a rod 12 having a fulcrum 9, a connecting part 10 and a hoe-shaped protrusion 11. The blowing hoe-shaped protrusion 11 is a receiving part 1 provided on the brake shaft 16.
4 to operate the hydraulic brake device 15,
By operating the drum brake 16, the wheels 17
to stop.

To explain the transmission mechanism step by step, first, when the driver applies the brakes while driving by gripping the steering wheel 18, the brake wheel 1 is also gripped. At this time, the brake column 2 is drawn toward the steering IJ wheel 18 side. Therefore, the connecting body 8 also moves upward along the longitudinal groove 7 at the same time.

The movement of the connecting body 8 is achieved by moving the protruding part 11 at the tip in the direction of the arrow about the fulcrum 9, and moving the receiving part 14 of the brake shaft 16, which activates the hydraulic brake 15 and activates the wheel 17. to stop.

2 and 6, 19 is a switch for the drive motor 20, 21 is a small gear for the motor 20;
is transmitted to the receiving portion 14 of the brake shaft 13 by a driven gear 26 having a tooth portion 22 meshing therewith, a hoe swelling portion 11, and a fulcrum 9. Furthermore, to explain the brake drive mechanism of this method in order, when applying the brake, first the motor 2
When the 0 switch 19 is turned on, the drive motor 20 rotates.

Along with this, the small gear 21 attached to the motor 20 also rotates at the same time, and the hoe bulge 11 at the tip of the driven gear 25 having teeth 22 moves the receiving part 14 of the brake shaft 16, thereby operating the hydraulic brake 15. The wheels 17 are stopped.

(6) In the case of C type In FIGS. 4 and 5, 24 is a brake handle lever, 25 is the shaft, and 26 is, for example, a rack and pinion gear that is provided integrally with the shaft and meshes with the gear 26. The information is transmitted to the driven gear 23 and the hoe expansion protrusion 1
1 moves in the direction of the arrow, and the receiving part 1 of the brake shaft 13
4 is moved, and the hydraulic brake 15 is activated to stop the wheel. In addition, 27 is a foot brake pedal, lf+
Le.

Effects of the Invention In the present invention, a brake shaft is provided with a receiving part, and the receiving part is moved by a hoe swelling part, but at this time, the foot brake pedal does not move. It does not affect the foot brake. Furthermore, when the 7-point brake pedal is depressed, the manually operated hoe protrusion does not move. In other words, there is no need to be concerned about the feet when using a manual brake, or about the brake wheel when using a foot brake, and braking performance can be improved because both types of brakes or each type of brake can be operated independently. In addition, the present invention is extremely useful industrially, such as allowing people with disabilities in either their legs or hands to drive without impairing braking performance. be.
