Abstract

The utility model relates to a clutch type assembling and disassembling machine for a tyre, which is suitable for repairing, inspecting and maintaining large automobiles. The utility model is formed by the method that one side of a belt pulley of an ordinary civil assembling and disassembling machine is provided with an automobile clutch. The bottom of a tetragonal frame body machine frame is provided with castors, and a motor is arranged in the frame body; the upper end of the machine frame is horizontally provided with a centre shaft on which a belt pulley is arranged; one end of the centre shaft is provided with a nut sheathing head which can act on a tyre nut. Consequently, the flexibility conduction of the rotational inertia and the automatic control for increasing and decreasing inertia in the process of screwing the nut are realized. The utility model has the advantages of reasonable and simple structure, flexible and convenient operation and good safety; compared with a common civil machine, the service life of the nut and the service life of an earthenware ring can be extended by eleven times.

Description

The disengaging type tyre removing and replacing machine

The utility model relates to a kind of full-sized car maintenance and maintenance disengaging type tyre removing and replacing machine.

Known motor vehicles for civilian use tyre dismounting machinery is by the electric motor drive belt pulley, and belt pulley drives colligator, and colligator directly drives axis degree of tightness nut; This rotation is the rigid transmission between a kind of metal piece, impulsive force is big, the increase and decrease control device accuracy of rotor inertia is low, caused the substantivity of lug nut screw mandrel to damage, tightness is easily fallen tire inadequately, and is not readily removable imperial in the excessive way of tightness, a plurality of nut unbalance stress, easily cause the damage of rim, noise is big during work.

The purpose of this utility model is that design proposes a kind of tyre dismounting machinery with flexible dynamic transmission device and rotor inertia increase and decrease automatic control.

The purpose of this utility model is achieved in that in normal domestic removing machine belt pulley side autoclutch being installed forms.Design tetragonal framework frame, castor is installed in its bottom, device electrical motor in the framework, frame upper end level is installed axis, the combination of belt pulley and power-transfer clutch is installed on the axis, protrude the moving carrying cylinder that connects of axis one end at position at the power-transfer clutch three-jaw, tube is outer to be with the power transmission of can conflicting of pressure bearing and power-transfer clutch three-jaw; Overcoat one sliding sleeve again, the sliding sleeve one side can be conflicted with pressure bearing, and another side and eccentric cam can be inconsistent.Can open positive and negative switch according to need of work, the handle that operates the clutch is conflicted eccentric cam or is separated sliding sleeve, sliding sleeve conflict pressure bearing, pressure bearing conflict or cut-off clutch three-jaw, to realize flexible dynamic transmission and transmission inertia increase and decrease automatic control.

Owing to adopt such scheme, thereby the suffered dynamics of nut is gentlely closed, steadily and evenly, compare, can improve ten times of nut and rim life-spans with the normal domestic removing machine, part dimension, velocity of rotation proportioning science, safe and reliable.

Below in conjunction with drawings and Examples the utility model is further specified.

Power-transfer clutch (7) is 130 or 212 automatic clutch assemblies, and a friction lining (28) is fixed as one with screw (11) and belt pulley (10), is enclosed within on the axis (18) through bearing (8) sky; Clutch-plate coincide with axis (18) spline again in it, as Fig. 1, Fig. 2.

Axis (18) is the garden axle of a wounded in the battle key of part, the nut pullover (27) that an end can supporting installation different size, and the other end and bearing (6) flush fit connects, and is fixedly installed in the carrying cylinder (5), as Fig. 1.

Carrying cylinder (5), it is a garden pillar buoy, be positioned at power-transfer clutch three-jaw back one end and and be fixed in garden axis of a cylinder on the frame (26) and hold flush fit and connect, be with on it can with the pressure bearing (4) of clutch three-jaw frictional rotation and conduction sliding sleeve (3) to pressure bearing (4) application force, as Fig. 1.

Sliding sleeve (3) is one to be enclosed within the sleeve on the carrying cylinder (5), and an end ring face can be conflicted with two eccentric cams (2), sees Fig. 1, Fig. 2, Fig. 3.

Eccentric cam (2) is two eccentric wheel, is fixed on the frame by two bearings (29), operates the transfer function power that rotates by clutch handle (31), as Fig. 3.

During work,, regulate power-transfer clutch three-jaw and removing machine and vehicle distances according to the supporting installation nut of different vehicle pullover (27); Open positive and negative switch (32), the dismounting of tire is realized in operating handle (30), (31) respectively.
