Abstract

The utility model discloses a power assisting device of an automobile clutch, which comprises a clutch master cylinder, a clutch pedal and a clutch slave cylinder. The clutch master cylinder is communicated with the oil inlet of the clutch power assisting slave cylinder through a hydraulic actuating pipeline. The device is characterized in that the clutch power assisting slave cylinder is communicated with a gas storage cylinder through a pressure actuating pipeline which is communicated with an air compressor. The outer end of a push rod on the clutch power assisting slave cylinder is hinged with a clutch rock lever. The power assisting device of the automobile clutch is safe and reliable, novel and simple in structure, convenient to operate, low in failure rate, thereby being especially suitable for application to clutch auxiliary power assisting systems of large-sized or middle-sized vehicles.

Description

The autoclutch work-saving device

Technical field

The utility model belongs to a kind of automobile power assisting device, specifically, relates to a kind of autoclutch work-saving device.

Background technology

The clutch system of automobile is an important link in the automotive transmission, by the chaufeur disengage the clutch, can make the automobile balance starting, interrupt power transmission in case of necessity, yet because various road conditions differences, need the frequent conversion gear of chaufeur, can make the leg muscle fatigue of chaufeur, strengthen labour intensity, particularly medium-and-large-sized car is because engine power and moment of torsion are bigger, need the strength of cut-off clutch friction lining big more, cause the strength of chaufeur stepping on clutch pedal big more, the easier chaufeur shank fatigue that makes.

Summary of the invention

Technical problem to be solved in the utility model is to provide a kind of safe and reliable and auxiliary work-saving device of labour-saving autoclutch.

The technical solution of the utility model is as follows: design-calculated autoclutch work-saving device, comprise clutch master cylinder, pedal of clutch and clutch power-assisted wheel cylinder, described clutch master cylinder is communicated with the oil inlet of described clutch power-assisted wheel cylinder through the hydraulic actuating pipeline, its main points are: the admission port of described clutch power-assisted wheel cylinder has air receiver through the pneumatic actuation pipeline connection, this air receiver is communicated with air compressor, and the push rod outer end on the described clutch power-assisted wheel cylinder is hinged with clutch rocker arm.

Thereby it is to be pushed away the reliable clutch that the gas mode reaches autoclutch by oil that the utility model adopts above structure, when motorist's let slip the clutch is stepped on, oil pressure in the clutch master cylinder increases, thereby open admission port in the clutch power-assisted wheel cylinder by hydraulic drive through the hydraulic actuating pipeline, thereby make the high pressure gas in the air receiver promote push rod in the clutch power-assisted wheel cylinder through the pneumatic actuation pipeline, thereby make pushrod movement promote the clutch slipper yoke of engine clucht, reach the effect of disengaging of clutch, require great effort very much when then stepping on the dynamic clutch pedal during air pressure out of reach certain pressure standard in the air receiver, can remind chaufeur vehicle abnomal condition, can not travel, thereby failure-free is braked automobile.

For the hydraulic oil in the clutch power-assisted wheel cylinder can not refluxed, on described hydraulic actuating pipeline, check valve is installed.

Beneficial effect: at the bottom of the utility model novelty simple in structure, easy to operate, safe and reliable, fault rate, be particularly suitable for adopting in the auxiliary force aid system of power-transfer clutch of big-and-middle-sized vehicle.

Description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the structural representation of the clutch power-assisted wheel cylinder 4 among Fig. 1.

The specific embodiment

The utility model is described in further detail below in conjunction with drawings and Examples:

Autoclutch work-saving device as depicted in figs. 1 and 2, by clutch master cylinder 1, pedal of clutch 2, air receiver 3, formations such as clutch power-assisted wheel cylinder 4 and air compressor 5, wherein said clutch master cylinder 1, pedal of clutch 2, air receiver 3, clutch power-assisted wheel cylinder 4 and air compressor 5 are prior art, do not give unnecessary details at this, be noted that: in the described clutch power-assisted wheel cylinder 4 first piston 44 is installed, second piston 45, push rod 46, poppet valve 47, the 3rd piston 48 and push rod 43, on this clutch power-assisted wheel cylinder 4, have oil inlet 41 and admission port 42(as shown in Figure 2), described clutch master cylinder 1 is communicated with the oil inlet 41 of described clutch power-assisted wheel cylinder 4 through hydraulic actuating pipeline 6, on described hydraulic actuating pipeline 6, check valve 8 is installed, the admission port 42 of described clutch power-assisted wheel cylinder 4 is communicated with air receiver 3 through pneumatic actuation pipeline 9, this air receiver 3 is communicated with air compressor 5, and push rod 43 outer ends on the described clutch power-assisted wheel cylinder 4 are hinged with clutch rocker arm 7.

The utility model is to come work like this: when chaufeur disengage the clutch 2, brake noise enters the inner chamber of clutch power-assisted wheel cylinder 4 from oil inlet 41, promoting first piston 44 moves to the left, increase along with pedal of clutch 2 strokes, the oil mass that enters clutch power-assisted wheel cylinder 4 increases, oil pressure is increased, brake noise will promote second piston 45 and move to the left, second piston 45 promotes push rod 46 simultaneously and moves to the left, when moving to the left, described push rod 46 promotes poppet valve 47, after poppet valve 47 is backed down, pressurized air enters from admission port 42, through passage, enter the 3rd piston 48 right side cavitys, along with the stroke increase of poppet valve 47, high pressure gas promote the 3rd piston 48 to left movement, thereby the push rod 43 that promotes to be fixed on described the 3rd piston 48 moves to the left, thereby promotes clutch rocker arm 7, realizes disengaging of clutch.

The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
