The clutch control device of the electric control road roller is provided with a control box; the control box consists of a pneumatic electromagnetic valve, a pressure switch and a throttle valve; the pneumatic electromagnetic valve is communicated with an external control signal, and the pressure switch is connected in series between the pneumatic electromagnetic valve and the gas circuit of the power cylinder to form a structure for driving the pneumatic electromagnetic valve to open the gas circuit to the power cylinder to act to realize the rapid separation of the clutch when the external control signal is received; the control box feeds back a clutch separation signal after detecting clutch separation; after the clutch separation signal is fed back to the control box, the external control signal is disconnected; a throttle valve is arranged in an exhaust hole of the pneumatic electromagnetic valve; and the throttle valve controls the exhaust speed of the power-assisted cylinder after the pneumatic solenoid valve loses an external control signal, so that the slow combination of the clutch is realized. The utility model discloses a separation and reunion is automatically controlled.
Description
Technical Field
The utility model belongs to the technical field of vehicle control, mainly relate to an automatically controlled road roller separation and reunion controlling means.
Background
The engine and the gearbox of the existing road roller in the market are usually connected in a hard connection mode, the power connection and disconnection of the road roller are achieved through a friction clutch connected to a flywheel of the engine, the clutch control of the road roller is generally achieved by controlling a master cylinder of a booster to introduce pressure oil into the booster to open a valve through stepping on a clutch pedal, compressed air in an air storage cylinder is introduced into the booster, and the action of a clutch moving plate is controlled through the action of the booster, so that the clutch is separated in a power-assisted mode. The clutch must be completely disengaged before each gear shift of the vehicle, and the slow engagement of the clutch after the gear shift can damage the gearbox and the clutch, all of which depend on the experience and the technology of the driver for operating the clutch pedal, and the operation labor intensity of the driver is increased due to the frequent operation of the road roller.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, the utility model aims at providing an automatically controlled road roller separation and reunion controlling means.
The utility model adopts the following technical scheme for accomplishing the above purpose:
the clutch control device of the electric control road roller is provided with a control box which is used for receiving an electric signal to drive a pneumatic electromagnetic valve to open a gas path to a power-assisted cylinder to act so as to realize the quick separation of a clutch; the control box consists of a pneumatic electromagnetic valve, a pressure switch and a throttle valve; the pneumatic electromagnetic valve of the control box is communicated with an external control signal, and the pressure switch of the control box is connected in series between the pneumatic electromagnetic valve and the gas circuit of the power-assisted cylinder to form a structure for driving the pneumatic electromagnetic valve to open the gas circuit to the power-assisted cylinder to act to realize the rapid separation of the clutch when the external control signal is received; the control box feeds back a clutch separation signal after detecting clutch separation; after the clutch separation signal is fed back to the control box, the external control signal is disconnected; a throttle valve is arranged in an exhaust hole of the pneumatic electromagnetic valve; and the throttle valve controls the exhaust speed of the power-assisted cylinder after the pneumatic solenoid valve loses an external control signal, so that the slow combination of the clutch is realized.
The boosting cylinder is composed of a cylinder with a return spring.
The utility model provides an automatically controlled road roller separation and reunion controlling means, control clutch fast separation when accepting the signal of telecommunication, feedback separation and reunion separation signal after the separation and reunion separation, control the slow joint of clutch when the disconnection signal of telecommunication to realize that the separation and reunion is automatically controlled.
Drawings
Fig. 1 is a schematic diagram of the present invention.
In the figure: 1. external control signal, 2, control box, 3, helping hand cylinder, 4 clutches, 5, feedback signal.
Detailed Description
The invention is described in connection with the accompanying drawings and the embodiments:
as shown in fig. 1, the clutch control device for the electric control road roller comprises a control box 2 and a power-assisted cylinder 3; the control box 2 mainly comprises a pneumatic electromagnetic valve, a pressure switch and a throttle valve, wherein the pneumatic electromagnetic valve in the control box 2 adopts three-port two-position 3V21008NCB1 produced by Adekey company, and after receiving an external control signal 1, the pneumatic electromagnetic valve opens a gas path and sends the gas path to the pressure switch; the pressure switch is connected in series between the pneumatic solenoid valve and the air passage of the power-assisted cylinder, the pressure switch adopts LF20H produced by Liff autonomous control company in Zhejiang, and when the pressure switch detects that the pressure of the power-assisted cylinder 3 reaches a set value, the contact acts to output a feedback signal 5 to judge that the clutch is separated; the throttle valve adopts a BESL02 throttle silencer produced by Adam corporation, the throttle valve is connected with a pneumatic solenoid valve exhaust hole, when the pneumatic solenoid valve loses a control signal 1, the gas of the boosting cylinder 3 is connected to the throttle valve exhaust through the pneumatic solenoid valve exhaust hole, so that the separation of the clutch is realized, and the separation speed is determined by adjusting the opening of the throttle valve; the power-assisted cylinder 3 is composed of a cylinder with a return spring, when the pneumatic electromagnetic valve is powered on, the power-assisted cylinder is inflated to enable the clutch to be separated and the cylinder spring to be compressed, and when the pneumatic electromagnetic valve is powered off, the power-assisted cylinder spring is reset to exhaust through the throttle valve.
Claims (2)
