Abstract

A novel permanent-magnet automobile clutch consists of a driving shaft, a driving disc, a driven disc, a magnetic pole, a non-magnetic disc and a spring, wherein the circular driving disc is stuck with the magnetic pole and provided with teeth, and the circular driven disc is provided with teeth on the end surface of the outer edge thereof. The cylindrical non-magnetic disc is sleeved on a splinedsleeve through an inner hole, and can enter or go out of the gap between the driving disc and the driven disc. When the clutch is closed, the magnetic clutch transmits the power of the driving disc to the driven disc through the magnetic force between the driven disc teeth and the driving disc magnetic pole. When the clutch is opened, the non-magnetic disc enters the gap between the driving discand the driven disc so as to form a closed magnetic circuit with the driving disc magnetic pole, and as the magnetic force of the driven disc teeth is small, the power of the driving disc can't be transmitted to the driven disc, which is equal to the separation of the clutch.

Description

The novel permanent magnetic automobile clutch

Technical field

The utility model relates to the clutch in a kind of car transmissions.

Background technique

Clutch all is housed between car combustion engine and the speed changer, generally adopts friction type; But this clutch wear and tear in use than very fast, the life-span is shorter; People have designed magnetic gear for this reason, but drive part is the same with traditional friction clutcch with actuating element, directly contact when clutch is operated; Still exist the friction and wear reliability relatively poor though installed release bearing additional.

The model utility content

The purpose of this utility model provides a kind of novel permanent magnetic automobile clutch; The magnetic pole of this clutch all is contained on the driving disc, only is shaped on the tooth that magnetic conduction is used on the driven disc; Inertia is less when the assurance transmission capacity is big.And the time not contacting in work of using of control clutch with driving parts every disk; Need not use release bearing, no friction and wear reliability is higher.

Structure of the present utility model is by driving shaft, driving disc, magnetic pole, driven shaft, driven disc, form every disk, spring, separation oil cylinder, clutch housing etc.Driving disc is that disc is fixed on the driving shaft, is bonded with on it by some magnetic pole is formed magnet ring; Driving disc also is shaped on and the corresponding tooth of magnetic pole; Driving shaft is the bent axle of internal-combustion engine.Driven disc is a disc, is shaped on the tooth that equates with driving disc magnetic pole number on it, is loaded on the driven shaft by spline.Driven shaft by bearings on driving disc.Make tubular every disk, on spline housing, the part that diameter is big can enter or withdraw from the space between driving disc and the driven disc by inner hole sleeve; Guide rod passes the hole on the clutch housing, and an end is fixed on disk, and the other end cover is useful on and makes the spring that keeps position, a left side every disk.Separate oil cylinder and be fixed on the clutch housing, be used to make move right every disk.

Working principle: during internal combustion engine, driving shaft drives driving disc and rotates together; When not stepping on clutch, the power of spring makes every disk and is in position, a left side, forms closed magnetic circuit between driven disc tooth and magnetic pole and driving disc and the tooth, and the magnetic force between driven disc tooth and magnetic pole and the driving disc tooth is big, the power of driving disc passes on the driven disc by magnetic force, is equivalent to clutch and " closes ".When stepping on clutch, separate oil cylinder and promote to move right every disk, the space and the driving disc magnetic pole that enter between driving disc and the driven disc form closed magnetic circuit, and the magnetic force that the driven disc tooth is subjected to is very little, the power of driving disc can not pass on the driven disc, be equivalent to clutch " from ".Because form two air gaps between the tooth on the novel permanent magnetic clutch driven disk for automobile and driving disc magnetic pole and the tooth, the magnetic force of generation is twice than the magnetic force that single air gap produces.And do not contact when working every disk, need not adorn release bearing with driving parts.

Description of drawings

Accompanying drawing is a tectonic maps of the present utility model, and 1 separates oil cylinder, 2 every disk, 3 splines, 4 driven shafts, 5 spline housings, 6 springs, 7 guide rods, 8 clutch housings, 9 bonnets, 10 magnetic poles, 11 driving discs, 12 driven discs, 13 internal combustion (IC) engine airframe, 14 bearings, 15 driving shafts, 16 driving disc teeth among the figure.

Embodiment

Driving disc in the accompanying drawing (11) is fixed on the driving shaft (15), coheres magnetic pole (10) on it; Driven disc (12) is loaded on the driven shaft (4) by spline; Driven shaft (4) passes clutch housing (8), is loaded on the driving disc (12) by bearing.Every disk (2) by inner hole sleeve on spline housing (5), spring (6) is enclosed within on the guide rod (7), separates oil cylinder (1) and is fixed on the clutch housing (8).

Claims

1, a kind of novel permanent magnetic automobile clutch is characterized in that: the structure of novel permanent magnetic automobile clutch is by driving shaft, driving disc, driven shaft, driven disc, form every disk, spring, magnetic pole, separation oil cylinder clutch housing; Wherein driving disc is a disc, is fixed on the driving shaft, is bonded with by some magnet rings that magnetic pole is formed on the driving disc and is shaped on and the corresponding tooth of magnetic pole; Driven disc is a disc, is shaped on its outer rim end face with driving disc magnetic pole number to equate tooth, and driven disc is loaded on the driven shaft by spline; Make tubular every disk, on spline housing, the part that diameter is big can enter or withdraw from the space between driving disc and the driven disc by inner hole sleeve; Driven shaft by bearings on driving disc.
