摘要:
A tyre changer actuating the tyre remover to move on a track tightly close to the rim flange and the tyre remover to run stably. The tyre changer comprises a clamp plate structure (4) ; two side clamp plates of the clamp plate structure are correspondingly provided with two arc-shaped guide slots (5) for a tyre remover; the guide slots guide the tyre remover to slide between the rim flange and the tyre bead along the contour of the rim flange; the two guide slots are vertically arrayed; and the tyre remover is located between the two side clamp plates. The structural features lie in that the upper end of the clamp plate structure is provided with a support body (8), and the upper end of the support body is connected to the lower end of a vertical actuator body (14) of the tyre remover.

A removal tool (10) for a tyre removing machine (1), for taking off a tyre (7) from a respective wheel rim (6), comprises an elongate body (12) having a first end (12a) which is connectable to a supporting arm (3) and a second, hook-shaped end (12b) for grasping a bead (14) of the tyre (7); the second end (12b) of the tool (10) has a fingernail shaped member (13) which is movable from a first operating configuration, where it projects in cantilever fashion from the body (12) to define the hooked shape, to a second operating configuration, where it is tucked in a lateral zone of the body (12), to give the tool (10) a hookless shape, and vice versa.
摘要:
A tyre-changing machine comprising support means (4) for a wheel, a tool- bearing arm (50) at an end of which a bead-breaking tool (6) is hinged according to a hinge axis (E) which is perpendicular to an axis (A) of the wheel, and first motohsed means (32, 33) for causing a relative movement, in a parallel direction to the axis (A) of the wheel, between the support means (4) and the tool-bearing arm (50), such as to press the bead-breaking tool (6) against a flank of a tyre on the wheel, characterised in that it comprises second motorised means (64), activatable independently from the first motorised means (32, 33), which second motorised means (64) are destined to rotate the bead-breaking tool (6) about the hinge axis (E) with the too- bearing arm (50), in order to vary an inclination of the bead-breaking tool (6) with respect to the axis (A) of the wheel which is mounted on the support means (4).
摘要:
Eine Vorrichtung zum Montieren oder Demontieren eines Luftreifens von einer Felge 1 eines Fahrzeugrades mit einem hakenförmigen Werkzeug 2, welches in einer Anlenkstelle 4 entlang einer Gleitführung 11 und in einer zweiten mit einem Lenkerhebel verbundenen Anlenkstelle an einem Werkzeughalter 5 gesteuert bewegt wird, wobei über ein Zahnradgetriebe 9 die Steuerbewegung eines stabförmigen Steuerteils 10 über das Zahnradgetriebe auf das Werkzeug 2 übertragen wird.
摘要:
An automatic device for mounting and removing a tyre (6) onto and from the relative wheel rim (5), comprising, for supporting the wheel rim (5) complete with tyre (6), rotary means associated with a frame (7) which supports an operating head (16), positionable in level and horizontally translatable, provided with at least one demounting tool (25) which can rotate about an axis perpendicular to the main axis of said operating head (16) to be positioned between a first position for seeking and gripping the bead of the tyre (6), in which the tool (25) is orientated towards the centre of the wheel rim, and a second position for extracting said bead of the tyre (6) from the wheel rim, in which the tool (25) is perpendicular to the axis or is orientated in the opposite direction.
