Abstract
The utility model relates to a novel clutch for a small motor vehicle. A structure of the novel clutch is composed of a releasing lever, a pulling rod, an adjusting screw, a clutch pressure plate, a driven plate, a clutch shaft, a disc spring and a belt pulley. The belt pulley of the clutch is molded by a whole steel plate in a spinning mode, and pressing force of the disc spring is adjusted through the adjusting screw, so that a friction plate can still be used when the friction plate is abraded to a certain degree. A working principle of the novel clutch is that when the vehicle normally runs, elasticity of the disc spring enables the clutch pressure plate and the driven plate to be tightly pressed, torsion produced by an engine is transmitted from the clutch pressure plate to the driven plate through friction force between the clutch pressure plate and the driven plate, and then the torsion is transmitted to a speed changing box through the clutch shaft. When power transmission of the vehicle needs cutting off, the outer end of the releasing lever drives the clutch pressure plate to move towards the right, the clutch pressure plate is contacted with the driven plate in a separated mode, the torsion produced by the engine cannot be transmitted from the clutch pressure plate to the driven plate, and the clutch stays in a separating state.
Description
Technical field
The utility model belongs to that vapour rubs and the accessory technical field.
Background technique
In China's short distance carrier, mini motor vehicle accounts for suitable ratio at present; And the belt pulley that clutch is installed in the small transporting vehicle mostly is cast member, casting defect such as trachoma, crackle very easily occurs and weight is big, cost is high; Clutch friction plate mostly is the plane friction, uses the friction plate attenuation of a period of time, promptly can not use after transfiniting, and working life is too short; And the video disc spring is subjected to frictional heat, and elasticity is died down, thereby has reduced the ability of transmitting torque.
The model utility content
The purpose of this utility model provides the automobile-used novel clutch of a kind of equipment of small motor, and the belt pulley of this clutch adopts monoblock steel plate rotary press modelling, has not only guaranteed intensity, but also has alleviated weight, stopped all defect of casting; When friction disc wear arrives to a certain degree, can adjust the impacting force of video disc spring by adjusting screw, friction plate just can continue to use like this; Above the platen of this novel clutch, increased one deck thermal-protective material, the video disc spring just can not reduce elasticity because of being heated like this.
Structure of the present utility model is made up of separator levers, pull bar, adjustment screw, clutch compressing disc, driven disc, clutch shaft, video disc spring, belt pulley and bearing.Wherein, belt pulley adopts the steel plate rotary press modelling, and its inner ring is shaped on tooth, is contained on the clutch shaft by bearing; Clutch compressing disc is a ring, and outer rim is shaped on tooth, and matching with the tooth of belt pulley inner ring passes to clutch compressing disc with power by belt pulley; Adhere to one deck thermal-protective material on the surface of contact of clutch compressing disc and video disc spring, to reduce the heat transfer that produces because of friction to the video disc spring, the phenomenon of avoiding the video disc spring elasticity to be died down because of being heated.Separator levers is contained on the belt pulley right side by bearing pin, and the outer end of separator levers links to each other with pull bar, and is inner corresponding with release bearing.One end of pull bar is fixed on the clutch compressing disc, and the hole that the other end passes on the belt pulley right side links to each other with the outer end of separator levers, be used to drive clutch compressing disc and move, thereby the releasing clutch compressing disc is applied to the pressure above the driven disc, makes clutch separation.Video disc spring outer rim is pressed on the clutch compressing disc, inner ring is pressed in pine and is enclosed within on the adjustment ring left side on the belt pulley right-hand member medial flange, its elastic force is used to make clutch compressing disc and driven disc to compress, produce frictional force between clutch compressing disc and the driven disc and make, the moment of torsion that motor is produced is delivered on the driven disc by clutch compressing disc, is delivered in the gearbox by clutch shaft again.Establish the adjustment screw in the belt pulley right side, when friction disc wear arrives to a certain degree, can tighten the adjustment screw moves left the adjustment hoop, the power that video disc spring outer rim is pressed on the clutch compressing disc does not reduce because of the wearing and tearing of friction plate, the clutch transmission capacity of avoiding causing because of friction disc wear reduces skidding of producing, and has prolonged the working life of friction plate.
Working principle: when normal vehicle operation, clutch is in bonding state; The elastic force of video disc spring compresses clutch compressing disc and driven disc, produces frictional force between clutch compressing disc and the driven disc and make, and the moment of torsion that motor is produced is delivered on the driven disc by clutch compressing disc, is delivered in the gearbox by clutch shaft again.When vehicle need interrupt transmission of power, release bearing promotes the inner of separator levers and swings left, the outer end drive clutch compressing disc of separator levers is moved right, disengage with driven disc, the moment of torsion that motor produces can not be delivered on the driven disc by clutch compressing disc, and clutch is in separated state.
Description of drawings: accompanying drawing is a tectonic maps of the present invention, and ring, (13) bearing, (14) clutch shaft, (15) bearing cap are adjusted in (1) separator levers, (2) pull bar, (3) clutch compressing disc, (4) driven disc, (5) telophragma, (6) video disc spring, (7) belt pulley, (8) thermal-protective coating, (9) bearing pin, (10) spline, (11) adjusting screw, (12) among the figure.
Embodiment
Accompanying drawing middle belt pulley (7) is loaded on the clutch shaft (14) by bearing (13); Clutch compressing disc (3) and telophragma (5) link together by tooth on it and belt pulley (7), and driven disc (4) is contained on the clutch shaft (14) by spline.
Claims (1)
1. automobile-used novel clutch of equipment of small motor, it is characterized in that: the structure of the automobile-used novel clutch of equipment of small motor is made up of separator levers, pull bar, adjustment screw, clutch compressing disc, driven disc, clutch shaft, video disc spring, belt pulley and bearing; Wherein, belt pulley adopts the steel plate rotary press modelling, and its inner ring is shaped on tooth, is contained on the clutch shaft by bearing; Clutch compressing disc is a ring, and outer rim is shaped on tooth, matches with the tooth of belt pulley inner ring, adheres to one deck thermal-protective material on the surface of contact of clutch compressing disc and video disc spring; Separator levers is contained on the belt pulley right side by bearing pin, and the outer end of separator levers links to each other with pull bar, and is inner corresponding with release bearing; One end of pull bar is fixed on the clutch compressing disc, and the other end passes the hole on the belt pulley right side, links to each other with the outer end of separator levers; Video disc spring outer rim is pressed on the clutch compressing disc, and inner ring is pressed in pine and is enclosed within on the left side of the adjustment ring on the belt pulley right-hand member medial flange; Establish the adjustment screw in the belt pulley right side, adjust screw and be used for regulating the position of adjusting ring, the power that video disc spring outer rim is pressed on the clutch compressing disc does not reduce because of friction disc wear.
