Description
(1) background technology
The present invention relates to a kind of mechanical drive road roller, especially relate to a kind of mechanical drive road roller clutch safety protection mechanism.Belong to the traffic engineering field of mechanical technique.
(2) background technology
The on-off control mechanism of the mechanical drive road roller of producing at present and using is the manual automobile of imitation mostly.Power-transfer clutch need be stepped on during gear shift by this mechanism, also needs to step on simultaneously power-transfer clutch during brake.When running into emergency, if maloperation is the not stepping on clutch pedal, directly steps on brake pedal and then can cause power-transfer clutch to burn.
(3) summary of the invention
The objective of the invention is to overcome above-mentioned deficiency; provide a kind of when running into emergency situation or maloperation; the driver does not have let slip the clutch; but directly step on brake pedal brake time, can realize the mechanical drive road roller clutch safety protection mechanism of the timely separation of power-transfer clutch in the time of braking.
The object of the present invention is achieved like this: a kind of mechanical drive road roller clutch safety protection mechanism, comprise the clutch control master cylinder, pedal of clutch, clutch power-assisted cylinder, air receiver, brake activation valve, the brake activation valve pedal, the air booster pump, the braking clamp, oil pipe, the 4th tracheae, second tracheae, the 3rd tracheae and first tracheae, described pedal of clutch is installed on the clutch control master cylinder, the brake activation valve pedal is installed on the brake activation valve, described clutch control master cylinder links to each other with clutch power-assisted cylinder by oil pipe, the compressed air outlet of described air receiver is divided into two the tunnel: the one tunnel and links to each other with an end of the 4th tracheae, the other end of the 4th tracheae links to each other with the admission port of brake activation valve, and another road links to each other with an end of second tracheae, the other end of second tracheae links to each other with clutch power-assisted cylinder, it is characterized in that: the air extractor duct of described brake activation valve is divided into two the tunnel: the one tunnel and links to each other with an end of the 3rd tracheae, the other end of the 3rd tracheae links to each other with the import of air booster pump, and the outlet of air booster pump links to each other with the braking clamp; And another road links to each other with an end of first tracheae, and the other end of first tracheae links to each other with the clutch control master cylinder.
The invention has the beneficial effects as follows:
The present invention distributes one tunnel pressurized air control clutch control master cylinder by brake activation valve; when running into emergency situation or maloperation; the driver does not have let slip the clutch; but directly step on the brake pedal brake; two-way pressurized air one tunnel enters the clutch control master cylinder and promotes the push rod cut-off clutch below the brake activation valve; another road enters the braking booster pump and realizes braking, and throw-out-of clutch makes clutch driving case no longer contact with clutch plate in the time of braking, thereby realizes the function of safety guard-safeguard.

Reference numeral among the figure:
Lubricating cup 1, pedal of clutch 2, first tracheae 3, clutch control master cylinder 4, second tracheae 5, clutch power-assisted cylinder 6, oil pipe 7, the 3rd tracheae 8, the 4th tracheae 9, the 5th tracheae 10, air booster pump 11, braking clamp 12, brake activation valve pedal 13, air receiver 14, brake activation valve 15.
(5) specific embodiment
Referring to Fig. 1, Fig. 1 is the overall structure scheme drawing of mechanical drive road roller clutch safety protection mechanism of the present invention.As seen from Figure 1; mechanical drive road roller clutch safety protection mechanism of the present invention mainly is made up of clutch control master cylinder 4, pedal of clutch 2, clutch power-assisted cylinder 6, air receiver 14, brake activation valve 15, brake activation valve pedal 13, air booster pump 11, braking clamp 12, oil pipe 7, the 5th tracheae 10, the 4th tracheae 9, second tracheae 5, the 3rd tracheae 8 and first tracheae 3.Described pedal of clutch 2 is installed on the clutch control master cylinder 4, and brake activation valve pedal 13 is installed on the brake activation valve 15.Described clutch control master cylinder 4 links to each other with clutch power-assisted cylinder 6 by oil pipe 7, described the 5th tracheae 10 1 ends link to each other with the pressurized air that described mechanical drive road roller driving engine produces, the 5th tracheae 10 other ends link to each other with the compressed air inlet of air receiver 14, the compressed air outlet of air receiver 14 is divided into two the tunnel: the one tunnel and links to each other with an end of the 4th tracheae 9, the other end of the 4th tracheae 9 links to each other with the admission port of brake activation valve 15, and another road links to each other with an end of second tracheae 5, and the other end of second tracheae 5 links to each other with clutch power-assisted cylinder 6; The air extractor duct of brake activation valve 15 is divided into two the tunnel: the one tunnel and links to each other with an end of the 3rd tracheae 8, and the other end of the 3rd tracheae 8 links to each other with 11 imports of air booster pump, and 11 outlets of air booster pump link to each other with braking clamp 12; Another road links to each other with an end of first tracheae 3, and the other end of first tracheae 3 links to each other with clutch control master cylinder 4.
Principle of work:
When driver's normal braking, let slip the clutch 2, promote clutch power-assisted cylinder 6 by the 4 fluid effects of clutch control master cylinder, step on brake activation valve pedal 13 when making disengaging of clutch, enter air receiver 14 by the pressurized air that driving engine produces via the 5th tracheae 10 this moment, the pressurized air that this moment, air receiver 14 was drawn enters brake activation valve via the 4th tracheae 9, distributes by brake activation valve then to enter air booster pump 11 via the 3rd tracheae 8, implements braking thereby drive braking clamp 12.
When running into emergency situation or the maloperation driver does not have let slip the clutch 2, but directly step on 13 brakes of brake activation valve pedal, the pressurized air that is entered by air receiver 14 is divided into two tunnel: one route, first tracheae 3 by brake activation valve 13 and enters the clutch control master cylinder, promote clutch power-assisted cylinder 6 by the fluid effect, promote push rod and make disengaging of clutch; Another route the 3rd tracheae 8 enters air booster pump 11 and enters braking booster pump control braking clamp realization braking, and throw-out-of clutch makes clutch driving case no longer contact with clutch plate in the time of braking, thereby realizes the function of safety guard-safeguard.Two actions are almost finished at the same time, clutch driving disc and clutch plate are thrown off does not like this have contact friction, thereby avoided because do not step on the directly power-transfer clutch that causes of the brake serious consequence of burning of clutch, if namely power-transfer clutch do not separate because of when braking change speed gear box drive the clutch driving disc driving engine that stops operating and still clutch plate at the high-speed operation band and rotate, the two relatively rotates at a high speed and produces friction and cause clutch plate to burn.Because its mechanism can realize two controls (can control clutch by pedal of clutch and also can pass through brake activation valve pedal control clutch), thereby can realize similar automobile automatic transmission function, gear shift namely can touch on the brake, greatly make things convenient for operation, avoided driver operation unskilled or run into emergency and deal with the original paper damage accident that causes improperly.
