Description

Vehicle Clutch Control

In particular, the present invention can be easily installed within a short time in a hydraulic line connected to a conventional booster cylinder without restructuring a vehicle, and the clutch pedal does not automatically operate even when a driver accidentally operates the clutch pedal. It relates to a clutch control device for a vehicle that can prevent accidents in advance.

Generally, a clutch refers to a mechanical element having a function of transmitting or interrupting power by mechanical contact from a drive shaft on a coaxial shaft to a driven shaft, wherein the clutch is installed between the engine and the transmission.

Here, the clutch performs a power transmission function for transmitting the rotational force of the engine to the transmission and a power cut function for temporarily shutting off the power flow between the engine and the transmission, and enables a smooth and vibration-free oscillation. It protects the engine and power train from overload as well as reduces the engine's rotational vibration with the flywheel.

The clutch as described above is largely, as shown in FIG. A master cylinder (3) for transmitting the force of the clutch pedal (1); An air pump 5 connected to the master cylinder 3 to supply air pressure; A booster cylinder (7) having a piston rod (7a) operated by receiving the pneumatic pressure supplied from the air pump (5); A release cylinder (9) for operating the clutch (11) with the pneumatic pressure provided by the booster cylinder (7); And a shift lever 13 hinged and connected to the release cylinder 9 and the clutch 11.

The push rod 9a of the release cylinder 9 has a return force by the spring 9b.

In the clutch configured as described above, when the driver presses the clutch pedal 1, the force actuates the piston rod 3a of the master cylinder 3 so that the pneumatic pressure supplied from the air pump 5 is the pneumatic induction part 51. Inflow into the booster cylinder (7), and the introduced air pressure moves the piston rod (7a) of the booster cylinder (7) to move the push rod (9a) of the release cylinder (9), the push The shift lever 13 separates the clutch disk of the clutch 11 from the driving plate of the engine by the movement of the rod 9a, and the power transmitted to the wheel is interrupted.

However, the clutch has a problem that not only increases the fatigue of the driver but also impairs the knees and the waist because the clutch pedal needs to be operated numerous times during the section or the slow running which is repeated for a long time.

In addition, in order to prevent the vehicle from starting, the accelerator pedal must be pressed while the foot pedal is released when the clutch pedal is released. When the start of the turn off, on the other hand, if the foot is released late, the power is not properly transmitted to the car there is a problem that the driving control of the vehicle is not good.

Meanwhile, in recent years, an automobile clutch control apparatus has been proposed to solve such a problem, but when the automobile clutch control apparatus is mounted on an automobile, the booster cylinder provided in the automobile is modified, and the valve is connected to the booster using a connection pipe. To be connected to the cylinder, the operation lever connected to the valve connected to the booster cylinder is inconvenient, etc. There is a problem that requires a high level of skill of the operator at the time of operation, the work time is long.

Accordingly, the present inventors propose a vehicle clutch control apparatus that can be easily installed in a short time without changing the vehicle structure.

The present invention was created to solve the above-mentioned problems, and in particular, it can be easily installed in a hydraulic line connected to a conventional booster cylinder without a structural change in a short time, and even if the driver accidentally operates the clutch pedal. It is an object of the present invention to provide a clutch control device for a vehicle that does not automatically operate the clutch pedal and thus prevents a safety accident.

In order to achieve the above object, the present invention provides a vehicle clutch control apparatus for controlling a clutch to be interrupted by the operation of a booster cylinder, the body; A valve unit installed in the body so as to be movable in the front-rear direction and having an opening / closing lever for controlling and exhausting compressed air introduced therein; An operation part for operating the opening / closing lever of the valve part; A detection sensor for detecting an opening and closing degree of the valve unit according to the operation of the opening and closing lever; A cylinder unit mounted to the body and having compressed air exhausted from the valve unit to move the valve unit; A piston cylinder connected to a hydraulic line connected to the booster cylinder, and having a piston rod mounted on the valve part to supply hydraulic pressure to the hydraulic line according to the forward and backward movement of the valve part; The control unit for controlling the operation unit; provides a vehicle clutch control device comprising a.

The valve unit may include: a housing having an inlet hole to which a hydraulic source for supplying compressed air is connected, a connection hole connected to the cylinder part and communicating with the inlet hole by a flow path, and an exhaust hole communicating with the flow path; An inlet valve which opens the flow path of the housing and supplies compressed air into the cylinder; An exhaust valve opening the exhaust hole of the housing to exhaust compressed air introduced into the cylinder part; And an opening / closing lever for opening and closing the inlet valve and the exhaust valve by the operation unit.

Furthermore, it is preferable that a spring is provided to open the exhaust valve when the operating part does not operate the opening / closing lever of the valve part by elastically supporting the front side of the opening / closing lever of the valve part.

The present invention can implement a semi-automatic transmission that does not need to step on the clutch pedal, such as an automatic transmission, while reducing transmission installation cost and fuel cost by using an existing manual transmission, and in particular, without changing the structure of the vehicle and the conventional booster cylinder Not only can be easily installed in the hydraulic line to be connected within a short time, the clutch pedal does not automatically operate even if the operator accidentally operates the clutch pedal, thereby preventing the safety accident accordingly.

In addition, due to the piston cylinder for supplying the hydraulic pressure to the hydraulic line in accordance with the forward and backward movement of the valve portion there is an effect that can be more easily performed the clutch pedal.

Furthermore, when the operating part does not operate the valve part, the spring elastically supporting the front side of the opening / closing lever opens the exhaust valve to exhaust the compressed air introduced into the cylinder part to the outside. There is an effect that can exhaust the air to the outside.
