Abstract: A piston and cylinder unit (1) of a working machine, for example a wheel loader, excavator, tipper, crane or stacker or a lifting platform serves to steer, support, extend, pivot, lift or other movements of the working machine or of a tool or a different part of the working machine. The piston and cylinder unit (1) includes a cylinder (2), a piston (7) being arranged in the cylinder (2) to be axially movable and a piston position detection unit (28) detecting the axial position of the piston (7) in the cylinder (2) by high frequency technology. The piston position detection unit (28) includes a housing (3) and an electronic unit being arranged in the housing is arranged in a mounting bore (27) extending radially in the cylinder (2). The piston position detection unit (28) is arranged in the mounting bore (27) such that the interior (3) of the cylinder (2) is sealed from the surroundings of the piston and cylinder unit (1) by the housing (29).

The piston and cylinder unit (1) includes a cylinder (2), a piston (7) being arranged in the cylinder (2) to be axially movable along a longitudinal center axis (54) and a piston position detection unit (28). The cylinder (2) includes a mounting bore (27) extending radially in the cylinder (2). The piston position detection unit (28) is arranged in the mounting bore (27) and detects the axial position of the piston (7) in the cylinder (2) by high frequency technology. The piston position detection unit (28) includes an antenna (46) for sending and receiving high frequency signals. A collimator (57) is arranged in the beam path of the antenna (26).

Abstract: A piston and cylinder unit (1) includes a cylinder housing (2), a piston (7), a piston rod (18) and a securing element (20). The piston (7) includes an opening (13), at least one piston seal (11) and an inner thread (15) being located in the opening (13). The piston rod (18) has an axis (9) and includes a protrusion (21), an outer thread (23) and a second thread (27). The outer thread (23) is located on the protrusion (21). The second thread (27) is located at the piston rod (18). The piston (7) and the piston rod (18) are connected by the inner thread (15) and the outer thread (23). The securing element (20) is designed and arranged to substantially extend in the direction of the axis (9). The securing element (20) includes a thread (24), the securing element (20) and the piston rod (18) being connected by the thread (24) of the securing element (20) and the second thread (27) of the piston rod (18).

Abstract: A piston and cylinder unit includes a housing, a piston and a piston rod. The piston rod has an outer surface being designed to be symmetrical with respect to a first axis. The piston rod includes a protrusion and an outer thread being located on the protrusion. The protrusion and the outer thread are designed to be symmetrical to a second axis. The second axis is spaced apart from the first axis to define a first eccentricity of the piston rod. The piston is located in the housing. The piston has an outer surface being designed to be symmetrical with respect to a first axis. The piston includes at least one seal, at least one guiding element, an opening and an inner thread being located in the opening. The opening and the inner thread are designed to be symmetrical to a second axis. The second axis is spaced apart from the first axis to define a second eccentricity of the piston.
