Abstract

The utility model relates to an auxiliary device for automobile starting, which is characterized in that the utility model is composed of an oil storage box and a circulation oil path composed of a power oil cylinder and a work oil cylinder, wherein a piston rod in the power oil cylinder is linked with a clutch pedal. In the work oil cylinder, a draw rod driven by a film sheet is connected with a gasoline throttle by a draw line. An oil seepage hole, a gearshift control oil valve, a one-way oil inlet valve and a one-way protective valve are arranged between the oil storage box and the circulation oil path. The gearshift control oil valve is controlled by a gear shift lever to be switched on and off, when the gear shift lever is at a first gear, the gearshift control oil valve is switched off, and on the contrary, the gearshift control oil valve is switched on. The utility model realizes that the contact of a clutch sheet and the opening of the gasoline throttle are linked with each other when the automobile starts, and the conditions of engine tremble and flameout because of inexperienced operation of a driver or unbalanced starting because of high gasoline throttle speed are avoided. The utility model causes the automobile to have balanced starting, and simple and easy operation.

Description

The car starting auxiliary device

Technical field:

The utility model relates to a kind of device that is used for auxiliary car starting.

Background technology:

The car starting requires chaufeur expertly to carry out interoperation to power-transfer clutch and throttle, accomplish " youngster pine clutch on one side, on one side youngster's open out ".If throttle is too small, the engine output power deficiency driving engine can occur and tremble, and causes even stopping working, if the throttle opening speed is too fast, can bring starting unstable, and this problem especially is present in the less car of discharge capacity.

Summary of the invention:

The utility model is for avoiding above-mentioned existing in prior technology weak point, a kind of car starting auxiliary device is provided, and makes car when starting, and loose power-transfer clutch and open out cooperate automatically.

The technical scheme that the utility model technical solution problem is adopted is:

Constructional feature of the present utility model is made of circulating oil path and the oil storage box that piston type actuator cylinder and diaphragm type operating cylinder form, wherein, drive piston rod and pedal of clutch interlock that piston advances in the actuator cylinder, in the operating cylinder, between axially movable pull bar under the drive of diaphragm and throttle, link to each other by backguy; Between described oil storage box and circulating oil path; oil seepage hole and the gear control fuel tap often opened are set; and make oil in the oil storage box be back to unidirectional inlet valve in the circulating oil path, by the unidirectional protection valve of circulating oil path to the oil storage box pressure release; the keying of described gear control fuel tap is controlled by shifter bar; its mode of operation is: when shifter bar is in one grade; gear control fuel tap is for cutting out, and when shifter bar was not in one grade, gear control fuel tap was unlatching.

Compared with the prior art, the beneficial effects of the utility model are embodied in:

1, the utility model realized the contact of clutch-plate and throttle be open at starting the time interlock, having avoided driving engine occurring owing to driver's operation is unskilled trembles, stops working, or open out excessive velocities and jiggly situation that starts to walk, make vehicle start more steadily, operation is easier easily.

2, the utility model is because the setting of the oil seepage hole of often opening, after starting is finished, oil in the circulating oil path infiltrates in the oil storage box in oil seepage hole gradually, oil pressure in the circulating oil path reduces gradually, pull bar resets under the effect of retracing spring gradually, and the influence of this device to engine throttle removed on automatic slowly ground.

3, the utility model is simple in structure, easy for installation, easy to implement, goes for the power actuated vehicle of various non-automatic shelves, self-acting clutch.

Description of drawings:

Accompanying drawing is the utility model structural representation.

Number in the figure: 1 actuator cylinder, 2 operating cylinders, 3 oil storage boxes, 4 pistons, 5 piston rods, 6 diaphragms, 7 pull bars, 8 oil seepage holes, 9 control fuel taps, 10 unidirectional inlet valves, 11 unidirectional protection valves, 12 retracing springs.

The specific embodiment:

Referring to accompanying drawing, present embodiment is to be made of jointly circulating oil path and oil storage box 3 that piston type actuator cylinder 1 and diaphragm type operating cylinder 2 form.Wherein, drive piston rod 5 and pedal of clutch interlock that piston 4 advances in the actuator cylinder 1, in the operating cylinder 2, between axially movable pull bar 7 under the drive of diaphragm 6 and throttle, link to each other by backguy.

In concrete the enforcement, between oil storage box 3 and circulating oil path, the oil seepage hole 8 often opened and gear control fuel tap 9 is set, wherein, the aperture of oil seepage hole 8 should than operating cylinder 2 to go into the oil circuit bore much smaller, the keying of gear control fuel tap 9 is controlled by shifter bar, its mode of operation is: when shifter bar was in one grade, gear control fuel tap 9 was for cutting out, at this moment, can be pressed in the operating cylinder 2 from the pressure oil in the actuator cylinder 1, implement to open throttle by operating cylinder 2; And when shifter bar was not in one grade, gear control fuel tap 9 was opening, because the short circuit effect that gear control fuel tap 9 is play in circulating oil path directly is pressed in the oil storage box 3 from the pressure oil in the actuator cylinder 1, operating cylinder 2 is not devoted oneself to work.

Simultaneously; as shown in the figure, between oil storage box 3 and circulating oil path, the oil that can make in the oil storage box 3 also should be set be back to unidirectional inlet valve 10 in the circulating oil path; with when oil pressure is too high in the circulating oil path, by the unidirectional protection valve 11 of circulating oil path to oil storage box 3 pressure releases.

The working process of vehicle being implemented starting is as follows:

At first, depress pedal of clutch, the piston 4 in Lian Dong the actuator cylinder 1 is moved to the left with it, and the oil in the oil storage box 3 injects circulating oil path by unidirectional inlet valve 10.When the shifter bar put in first gear, gear control fuel tap 9 cuts out immediately;

Subsequently, release the clutch pedal progressively, piston 4 in the actuator cylinder 1 advances to the right because of interlock, oil in the circulating oil path is pushed in the operating cylinder 2, at this moment, though oil seepage hole 8 is arranged for often opening, but because of the aperture of oil seepage hole 8 much smaller than the oil circuit bore of operating cylinder 2, infiltrating the unlikely operating cylinder 2 that has influence on of oil mass in the oil storage boxes 3 from oil seepage hole 8 obtains enough oil pressure and is under the normal working, along with the rising of oil pressure, diaphragm 6 bulging to the left in the operating cylinder 2, pull bar 7 thereby drive throttle by backguy and progressively open, the horsepower output of driving engine progressively strengthens, and vehicle is started to walk with the joint of power-transfer clutch.

After starting, piston 4 stops to advance to the right, and subsequently, the oil in the circulating oil path progressively infiltrates in oil storage box 3 through oil seepage hole 8, progressively pressure release of operating cylinder 2, and under the effect of retracing spring 12, pull bar 7 is removed the influence to throttle gradually.

When shifter bar was not in one grade, gear control fuel tap 9 was opening, because the short circuit effect that gear control fuel tap 9 is play in circulating oil path directly is pressed in the oil storage box 3 from the pressure oil in the actuator cylinder 1, operating cylinder 2 is not devoted oneself to work.
