Abstract
Description
【発明の詳細な説明】 本発明は車両の制動力保持装置に関するものである。[Detailed description of the invention] The present invention relates to a braking force retention device for a vehicle.
例えば今日の一般的トルコン車では、信号待ち等で停止

低速で前進してしまう。For example, in today's general torque converter vehicles, the vehicle will move forward at low speed unless the vehicle performs a pre-kinder due to the creep phenomenon when stopped, such as when waiting at a traffic light, or sets the torque converter range to neutral or hyperking.

中にカップが膨らんだ状態で通過することになる。従っ
て鮮らんだカップに傷がつく欠点があった。Conventionally, a type of brake fluid sealing system has been proposed as a countermeasure for the above-mentioned problem, but in this method, once the brake pedal is depressed, the fluid pressure rises in the piston stroke of the mask cylinder and moves to the hole leading to the retuber. The cup will be passed through in an inflated state. Therefore, there was a drawback that the bright cup would be damaged.

号を入nてやらない限り、再ブレーキはがけられない。Also, conventionally, if you stop by applying the brakes and continue for about 2 seconds, the electromagnet will be activated and the adsorption plate will be activated. Japanese Patent Publication No. 7100/1983 has proposed a braking force retention device for a vehicle that prevents the brake pedal from being depressed again by adsorption. This (/-1 device) When the brake force is insufficient after the first depression, even if you try to apply the brake again, the brake pedal is fixed and you cannot press it again, so you can press the accelerator pedal and release the electromagnet. A switch is activated to remove and remove excitation, but the brake cannot be applied again unless another signal is applied.
もつとも電磁石励磁のまま再ブレーキ全強力にかけると
、電磁石に吸着された吸着板が滑るようにはなっている
が、この状態を繰返えすと吸着板の摩耗が激しく、好ま
しくない。Of course, if the brake is applied to full strength again while the electromagnet is still energized, the adsorption plate attached to the electromagnet will slip, but if this condition is repeated, the adsorption plate will become severely worn out, which is not desirable.

うにしたものである。The present invention attempts to eliminate the above-mentioned conventional drawbacks by using a spring-type one-way brake.In addition to providing a rotating member that interlocks with the brake pedal VC,
It has a coil portion that is to be frictionally engaged with the circumferential surface of the rotating member, one fixed end, and the other end, and by displacing the other end, the coil portion is frictionally engaged with the circumferential surface of the rotating member. Under this state of frictional engagement, the rotating member is allowed to rotate as the brake pedal is depressed, but when the rotating member attempts to rotate in the opposite direction, the rotating member wraps around the rotating member and rotates. A spring member for preventing reverse rotation is provided, and the other end of the spring member is normally kept in a free state so that the coil portion does not engage frictionally with the circumferential surface of the rotating member and the rotating member can freely rotate in the reverse direction. When the braking force is to be maintained, the actuator displaces the other end of the spring member to frictionally engage the coil portion with the circumferential surface of the rotating shaft, preventing the oral member from rotating in the opposite direction, and then pressing the brake pedal. By holding the brake pedal in the depressed position, the braking force is maintained as if the brake pedal is kept being depressed when the vehicle is stopped, and the brake pedal can be depressed again without difficulty.

In addition, a large holding force can be obtained by a self-leading action (one-way clutch action) for holding the pedal, and a small force sufficient to force the locking member by σ1 is sufficient for holding and releasing the pedal. Furthermore, even if the control unit that controls the actuator malfunctions, the braking force retention function is not lost, and the brake pedal depression and return operations are ensured, resulting in high safety.

The pinion gear 9 is provided so as to rotate integrally on a shaft Jl that rotatably passes through a bracket 10 fixed to the bracket 2 with a bolt 6. A rotating member 12 located on the opposite side of the pinion gear 9 of the bracket 10 is also provided so as to rotate together on the shaft 11. A spring member 1B is arranged on the outer peripheral side of the rotating member 12. This spring member 18 is the rotating member 1

Under this state of frictional engagement, when the rotating member 12 attempts to rotate counterclockwise in the first sentence, the frictional force between the coil portion 13a and the rotating member 12 acts to completely reduce the diameter of the coil portion 13a. As a result, the coil portion 18a is wound around the rotating member 12,
This prevents rotation of the rotating member 12. On the contrary, when the rotating member 12 attempts to rotate clockwise in FIG. The part 18a is a rotating part phase 1 that is wound around the rotating member 12.

12nに摩擦係合する。Next, the effect will be explained. When the brake pedal 1 is depressed, the pedal 1 rotates clockwise about the pin 8 in FIG. 1, and the brake mask cylinder M-i is actuated through the entire bushing end 41 to generate braking force. At the same time, the pinion gear 9 rotates around the rank gear 5 fixed to the pedal 1 or the pin 8 as a fulcrum and meshes with its teeth 8.
The rotating member 12 integrated with the pinion gear 9 rotates clockwise in FIG. 19 is the rank gear 2 that meshes with the 1st gear
1, f, the sliding member 21 having the sliding member 21 is slid toward the upper left in FIG.
With a displacement of 8c, the coil II (138) frictionally engages with the circumferential surface 12n of the rotating member 12.

再踏み込み位置に固定され、制動力が保持される。Therefore, when you stop pressing down on the brake pedal 1, the return spring causes the pedal 1 to return, and along with this, the rotating member 12 exerts a force! Although the brake pedal 1 attempts to rotate counterclockwise in FIG. 1, the brake pedal 1 is held at the depressed position because the brake pedal 1 wraps around the rotating member 12 and prevents the rotating member 120 from rotating counterclockwise. The braking force is maintained by 2'L. At this time, if the brake pedal (1) is not depressed enough and the vehicle moves forward or backward at low speed, the brake pedal (2) that has been set (fj14) may be depressed again. At this time, the rotating member 12 again rotates clockwise in FIG.
Next, when the pressure on the brake pedal l is released, the rotating member 1
When the brake pedal tries to rotate counterclockwise again in FIG. 1, the rotation is blocked, so the brake pedal (2) is fixed at the re-depressed position and the braking force is maintained.

Due to Cn, the diameter of the coil portion 3a of the spring member 13 is expanded and separated from the circumferential surface 12R of the rotating member 12, and the rotating member 12 can be rotated counterclockwise in FIG. returns and rvt1 power is eliminated.
