Abstract

PURPOSE:To certainly prevent the back movement of a car on starting on a slope by installing a back-movement preventing mechanism equipped with a ratchet wheel apparatus for preventing back movement and a solenoid for driving the pawl of the ratchet wheel onto a shaft on the driven side and controlling said mechanism by an electronic control circuit. CONSTITUTION:A brake pedal is stepped-in to stop a car traveling on an ascent and a clutch pedal is stepped-in when a low speed is realized, and then switches SW2 and SW1 are closed in succession. When the car stops, the output of an OR-circuit 20 is put into low level by the NAND in a NAND circuit 24 into which also the signal (a) of a revolution-number detector is input, and a transistor Tr1 is turned OFF. Therefore, also Tr2 is turned OFF, and a solenoid 14 is deenergized, and the pawl 9 of a ratchet wheel apparatus 11 shifts to a position for engaging with the ratchet wheel 10 by the aid of a spring 13 and engages with the ratchet wheel 10, and thus back movement of the car is prevented. When the clutch is put into connection state to advance the car, the solenoid 14 is excited, an the pawl 9 is retreated from the ratchet wheel 9.

Description

DETAILED DESCRIPTION OF THE INVENTION This invention provides a system for starting a device when a force is applied in the opposite direction to the 8th time a vehicle such as an automobile+111 attempts to proceed, such as at 10 o'clock on a steep slope. This invention relates to a reverse movement prevention device W that makes driving easy to dispose of and completely prevents reverse movement.

Conventionally, when starting a vehicle such as an I-Ha car on an uphill slope, one presses down on the accelerator, leaves the clutch in a half-clutch state, releases the side brake, and then fully engages the clutch to prevent the vehicle from moving backwards. It's starting.

Therefore, it is necessary to be skilled at the starting operation, and collisions and rear-end collisions are likely to occur. A similar drawback exists with respect to starting in WfFt, a mechanism in which a force is applied in the opposite direction to the drive direction.

This invention was made in order to solve the problems of the conventional technology as described on paper, and it is equipped with a ratchet wheel to prevent driving on the driven 11+lI 1lQll, and a solenoid that drives the toothed ratchet on the ratchet wheel. The electronic side OAi operates as a reverse rotation prevention mechanism consisting of a reverse rotation prevention mechanism and a spring, the rotational speed of the driving side shaft and the driven side 1ξ11, the state of the clutch, the state of the flakes, and the state of the transmission. 1ijl

FIG. 4 shows an embodiment of an electronic control circuit CP that determines the desired input data and controls the excitation value of the solenoid 14 of the ratchet wheel device 11 by turning it on and off.
It's not something that can be contained.

In the figure, the solenoid 14 is a transistor TrI+T
2F consisting of r2 and diode IJ-/P! The image is moved by a solenoid drive circuit 18 on the platform width.

-1 If 2 and W are correct, then when starting and starting, when stopping the vehicle, the driver usually depresses the brake pedal 8, and when the vehicle speed decreases and the engine speed becomes low, the driver presses the clutch pedal T. When is stepped on, the switches SW2 and SW switch each pedal 8,
7 is fully detected and input inverted to the NAND circuit 24 of the arithmetic circuit 19, and when the vehicle stops due to braking, 4FB indicating the rotation of the driven side shaft 3a from the 11 rotation speed detector A. ``j' a is one shot multi 2
5, the stoppage of the driven shaft 3a is detected and input to the NAND 1 path 24, and these NAND 11
Due to the NAND input of the 21 path 24, the output of the ORi+'' path 20 becomes a low level, and the transistor T of the drive circuit 18
r+k is turned off, so the transistor Tr is turned off, the solenoid 14 is de-energized, and the spring 13 is turned off.
The pawl 9 moves to a position where it locks the ratchet wheel 10, thereby locking the driven shaft 3a against reverse rotation and preventing the vehicle width from moving backward. However, in this case.

The gear shifter 1 5a is not in the reverse position IN, and the inverter 1. is at a low level, and the output of the comparator 21 is at a low level (
Driven (the number of rotations of the 111 East 113a and the Drive 1st II Wholesale 33b must not be -'':v) All sales are limited to 1 ship.

Next, when starting the vehicle, the operation 8 is the same as a normal start, and the accelerator (not shown) is pressed down, the engine is revved up, and the clutch pedal 1 is used to set the clutch lever 4 in a half-engaged state.

When the clutch 4 is fully engaged, when the number of revolutions is 1, the frequency of the engine A is high, the frequency of the engine C of the engine B is high, and the converter 22 and 1.'-V Conoverter 23's output pressure is 75 clear, it becomes I, and the start is '4.
At this time, the output of the throat comparator 21 becomes a high level, and the output of OR: River #'i'; When excited, the pawl 9 is locked to the ratchet wheel 10 ff: released.

If the engine stops at this time, comparator 2
1's output becomes low level, and as a result, the solenoid 14 becomes de-energized.According to the bias of the spring 13, the clasp 9 engages and locks the east 10, locking the driven side lll1ll3a to prevent reverse rotation, and locking the axle. prevent it from going backwards. In other words, if the rotation speeds of the driven shaft 3a and the driving shaft 3b do not match, it is determined that the engine is in the process of starting or has failed to start.
However, the solenoid 14 is not energized, and therefore, the pawl 9 and the ratchet wheel 10 remain engaged and locked, thereby preventing the vehicle from moving backwards due to a failure in starting.

In addition, even if both the brake pedal 8 and the clutch pedal I are depressed and the vehicle speed is detected to be zero, if the gear lever 6 is in the reverse position/V switch 5V
v3 on, inverter 13 output is sieve level, OR l+
:The output of the il path 20 is still at the level, and the solenoid 14
The combination of 1 and 9 and 1Z1i) does not mesh and there is no problem for the eastern back.

In the above, an example has been shown in which the state of the clutch, brake, and the backward position of the fishing boat is detected by the detection pedal or carrier, but the number to be detected is not limited to the above.

As described above, this invention completely prevents reverse movement by using the clutch jlj fixed at 1-.1 for the driven 1MII 111+ and the pawl provided so as to be able to engage and disengage it, and also prevents the clutch's human power i11:I and the output 1t41+ The electronic control circuit +
By using C and linking these signals and the operation of the pawl, it is configured to detect failures in stop and start of city axes, etc., and completely prevent vehicles, etc. from moving backwards.
To prevent a vehicle from going backwards when starting on an uphill slope, and to make starting easier. It can also be applied to all products that have 8 suctions to prevent back movement.
