Abstract
The spiral spring clutch with automatic compensating packing force of the utility model mainly is composed of a clutch cover, a spiral spring, a releasing lever and a clutch pressure plate. A supporting base whose outer diameter is smaller than the inside diameter of the spiral spring is hinged between the clutch pressure plate and the clutch cover. The central shaft line of the supporting base forms a theta angle with the central shaft line of the clutch. The utility model can automatically compensate the pressing force acting on the driven plate in the working process of the clutch, and can extend the service life of the clutch.
Description
(1) technical field: the utility model belongs to auto parts and components, is specifically related to a kind of coil clutch of automatic compensation impacting force.
(2) background technique: existing coil clutch, as shown in Fig. 1, Fig. 2, mainly comprise clutch cover 1, helical spring 2, separator levers 3, clutch compressing disc 4, its working principle is that helical spring pressure acts on the platen, driven disc is pressed on the flywheel again.Suppose that whole spring rate is K
1, the decrement of spring is S
1, act on the impacting force F on the driven disc so
1=K
1* S
1, along with constantly engaging in the rotation process of clutch, driven disc constantly weares and teares, and clutch compressing disc is moved to the left under helical spring effect, the elongation of spring length, amount of spring compression S
1Reduce, platen acts on the impacting force F of driven disc thereupon
1Also linearity diminishes gradually.When impacting force is little when the certain value, clutch begins to show the transmission deficiency, cltuch slipping occurs, burns fault such as sheet, and clutch is scrapped thereupon.
(3) summary of the invention: the purpose of this utility model proposes a kind of clutch working life of prolonging, the coil clutch with automatic compensation impacting force exactly.
Coil clutch of the present utility model, the same with prior art have clutch cover, helical spring, separator levers and a clutch compressing disc, improvements are that hinged external diameter is less than the helical disk spring inside diameter between platen and clutch cover, and its central axis and clutch core axis are the bearing at θ angle.
The span at above-mentioned θ angle is 0-90 °.
When helical spring central axis and clutch core axis at angle during θ, act on impacting force on the driven disc and be helical spring pressure along the component that clutch shaft makes progress, again driven disc is pressed on the flywheel.The rigidity of supposing whole spring is K
2, the initial compression amount of spring is S
2, act on the impacting force F on the clutch driven plate so
2=K
2* S
2* cos (θ), along with in the rotation process of clutch, clutch constantly engages, and driven disc constantly weares and teares, and clutch compressing disc is moved to the left under helical spring effect, the elongation of spring length, S
2Reduce, but θ reduces simultaneously, because span at 0-90 °, so this moment, cos θ increased, makes impacting force F thereupon
2Not to be linearity to reduce, but make driven disc after wearing and tearing, impacting force has been played compensating action, prolonged the working life of clutch.
(4) description of drawings:
Fig. 1 is existing coil clutch master apparent direction structural representation;
Fig. 2 is an A-A direction sectional structure schematic representation among Fig. 1;
Fig. 3 is a coil clutch master apparent direction structural representation of the present utility model;
Fig. 4 is a B-B direction sectional structure schematic representation among Fig. 3.
(5) embodiment:
Referring to Fig. 3, Fig. 4, the hinged bearing 5 of internal diameter between clutch compressing disc 4 and clutch cover 1 less than helical spring 2, and the central axis of the central axis of this spring support 5 and clutch is 0-90 ° of angle.
Claims (2)
1. compensate the coil clutch of impacting force automatically, mainly have clutch cover [1], helical spring [2], separator levers [3], clutch compressing disc [4], it is characterized in that: hinged external diameter is less than the bearing [5] of helical spring internal diameter between described clutch compressing disc and clutch cover, and the central axis of this bearing and the central axis of clutch are the θ angle.
2. the coil clutch of automatic compensation impacting force according to claim 1 is characterized in that: the span at described θ angle is 0-90 °.
