Abstract

The utility model discloses a release yoke for an automobile clutch with labor-saving function which is suitable for mechanical clutches, such as the clutches of a DongFeng 140, a JieFang 10, a JieFang 141, a bus, etc. The utility model is characterized in that the release yoke of the original automobile clutch is lengthened, and the release yoke is bended with a definite angle along the center line of the release yoke. When the utility model is installed on a DongFeng 140, the length of travel can reach 3, 000 kilometers via the one-month probation by a driver. Compared with the automobiles which are not provided with the utility model, the driver feels easy when stepping on the clutch pedal obviously, and the labor which is one to two times as big as the original labor is saved. A clutch provided with the utility model is as good as an oil pressure type clutch arranged on an imported automobile, the life time of any component is not affected, and the driving is more smooth and easy.

Description

Release yoke of automobile clutch with power saving function

The utility model is a kind of autoclutch operating fork, the parts that belong to power-transfer clutch, be applicable to east wind 140, the old and new's Jiefang brand automobile, and the various passenger trains that formed by this class automobile repacking, it is to improve on the basis of former automobile machinery power-transfer clutch or convert.

Fig. 1 is the part assembly drawing of former autoclutch, wherein 1 is pedal, the 2nd, pedal arm, the 3rd, the operating fork adjusting lever, the 4th, operating fork, its shortcoming be operating fork 4 connect too short and its line of centers of an end length with adjusting lever 3 be straight line, the operating fork adjusting lever 3 that connects pedal arm 2 and operating fork 4 is about 90 ° with the angle that is connected of pedal arm 2 and operating fork 4 respectively, according to mechanics and bar thick stick principle.And the relation of angle between lever, this structure is very laboriously when the pin stepping on clutch, this has brought white elephant for the particularly long-distance driver of driver on muscle power, and because heavy, so be not easy to grasp steadily, occur violent combination during initial starting shift easily, part parts life-spans such as transmission are all had certain influence.

The purpose of this utility model is to overcome the shortcoming of above-mentioned clutch throw-out fork and a kind of laborsaving operating fork of design-calculated.

Feature of the present utility model is that this length is as the criterion with the attachment point of operating fork and operating fork adjusting lever with the 70～80mm that extends on original basis of the operating fork on the former automobile; And be as the criterion 120 °～160 ° angle of operating fork line of centers.

Fig. 1 is the part assembly drawing of former autoclutch;

Fig. 2 is the utility model operating fork detail drawing;

Fig. 3 is the part assembly drawing of the utility model autoclutch;

Fig. 4 is the clutch part assembly drowing that former automobile operating fork is adapted as the utility model structure.

Describe structure of the present utility model in detail below in conjunction with accompanying drawing.

Structure of the present utility model is shown in Fig. 2,3, and 1 is pedal, and 2 is pedal arm, 3 is the operating fork adjusting lever, and 4 is operating fork, and operating fork 4 is as the criterion to bend with line of centers X-Y an angle, this angle is 120 °～160 °, the long 70～80mm of the length of operating fork 4 more former autoclutch operating forks.One end of operating fork adjusting lever 3 fixedly is assemblied in the hole of an end of operating fork 4 elongated portion, and the length of operating fork 4 lengthenings is to be as the criterion with the attachment point A with operating fork adjusting lever 3.Adjust the length of operating fork adjusting lever 3 and spring-loaded length on it according to the size of above-mentioned operating fork 4, the length of spring or on operating fork adjusting lever 3, add the method that tubing withstands spring and realize of can taking to extend.Sleeve pipe is India rubber tube or plastic pipe etc.

Fig. 4 is adapted as the operating fork of the utility model structure and the assembly drowing of other parts of power-transfer clutch with former automobile operating fork, is to be with an end of the extension element 5 of certain angle to be fixed in the stomidium of former operating fork 4, and the other end has the hole.Operating fork adjusting lever 3 fixedly is assemblied in this hole.5 bending angles of extension element can be between 120 °～160 °, after former operating fork 4 and extension element 5 usefulness screws are fixing, are as the criterion the long 70～80mm of more former operating fork with the attachment point with operating fork adjusting lever 3.Spring-loaded length on the length of operating fork adjusting lever 3 and its.Size according to operating fork 4 is adjusted.In order to ensure the operating fork return, can adopt the spring on the lengthening operating fork adjusting lever 3 or utilize former spring to add tubing and withstand spring and realize.

The utility model is applicable to mechanical clutch, such as east wind 140, and liberation 10,141, motor buses etc. adopt Fig. 4 structure to be contained on east wind 140 cars. On probation through the driver Stroke was 3,000 kilometers in one month, compared with being unkitted the utility model structure automobile, and obvious feeling relaxed during pin stepping on clutch pedal is economized 1～2 times strength approximately, compared sensation with institute's charge of oil pressure type clutch on the imported auto quite. And do not affect any parts life-span, on the contrary more steadily easily, can thoroughly separate, again steadily thoroughly combination.

Claims

1, the laborsaving disengaging bar of a kind of autoclutch is made up of pedal 1, pedal arm 2, operating fork adjustment fork 3, operating fork 4, it is characterized in that the operating fork on the former automobile 4 is increased certain-length, and curved there is certain angle to constitute laborsaving operating fork 4, the length that increases is with operating fork 4 and the operating fork adjusting lever 3 attachment point A lengthening 70～80mm that is as the criterion, and curved angle is as the criterion 120 °～160 ° with operating fork 4 line of centers X-Y.

2, the laborsaving operating fork of autoclutch as claimed in claim 1 is characterized in that said lengthening and curved angled operating fork 4, can make an integral body; Also can on former automobile operating fork 4, connect an extension element 5 with certain angle, after former operating fork 4 and extension element 5 are connected and fixed, be as the criterion with the attachment point of extension element 5 with operating fork adjusting lever 3, more former automobile operating fork 4 long 70～80mm, 5 bending angles of extension element are 120 °～160 °.
