The present invention relates to torque application tools, such as an electronic torque screwdriver, with a multiple axis gyroscope (such as a 3-axis gyroscope or other type of gyroscope) and torque sensor that allows for simultaneous or sequential measurement of torque and angle around the axis of the tool. Targets for torque and angle measurements may be used to create algorithms to detect breakaway torque, residual torque, or to perform error proofing to ensure unique fasteners are tightened.

An impact tool includes a housing, a rotating hammer arranged in the housing and rotatable by a motor, and a rotating anvil arranged in the housing and rotatable by the hammer by a series of impacts. An output shaft has a proximal end fixed to the anvil and a distal end protruding from the housing and ending with a fitting element for removable connection with an external mechanical adapter. A sensor unit includes a rotational torque sensor for detecting a torque of the shaft. The torque sensor includes at least one extensometric transducer fixed to an outer surface of a cylindrical portion of the distal end adjacent to the fitting element to detect a deformation signal that is proportional to a deformation of the outer surface when the shaft is rotated and indicative of the torque. The sensor unit further includes a rotating electronic module connected to the extensometric transducer and includes a microprocessor for conditioning the deformation signal, the rotating electronic module being shaped in such a manner to surround the cylindrical portion and mounted to rotate integrally with the rotating output shaft.

A screwing tool for an impact wrench for screwing wheel nuts onto and off from a hub body for securing a vehicle wheel, having a main body, which has an open side oriented toward the wheel nuts and which includes a hollow profile. The hollow profile has a tool contour, which is arranged on the open side and can be brought into engagement with a wheel nut contour. At least one peripheral control edge is remote from the open side for releasing a retention element. The control edge has a circular arc region with a constant control edge height h.sub.1 and a cam region with a control edge height h.sub.2 that decreases continuously and then increases again continuously. Height h.sub.1 is equal to h.sub.2 in the respective transition of the circular arc region and the cam region, such that the geometrical shape of an oval is reproduced in cross section.

Clamp devices can be operated remotely to facilitate the installation, removal and other handling of wheels and tires for large vehicles. The clamp devices generally include an attachment mechanism, a gripping mechanism, an actuating link operable to move the gripping mechanism between an open and closed position, an actuator to activate the actuating link, a transmitter for sending command signals to the clamp devices for the purpose of opening or closing the gripping mechanism and a receiver for receiving such command signals.

The present invention provides an improved device for simultaneously replacing a plurality of lug nuts through the use of computer technology, modularity, energy-efficiency, safety features and ease of use. Computer technology monitors and controls the torque on each lug nut. This invention also displays the loosening or tightening status of each lug nut on a small LCD screen. The present invention achieves modularity through a series of interchangeable gear train assemblies, contained in separate unitary housings, which correspond to respective vehicular wheel depth and wheel lug patterns. Also, magnetic concentric sockets are used to capture and hold lug nuts as they are removed from the vehicle's wheel and to remove and replace theft protection devices such as rim or wheel locks. This invention provides ease of use with user-friendly controls and a light-weight unitary housing that eliminates the need of assistance from another person.

A tightening device is able to check that a fastening member has been fastened to a desired set torque or greater after being tightened, without loosening the fastening member. The tightening device is provided with a mode switching switch for switching between a first tightening process of adjusting the output of a motor after measured torque that is measured by a torque detector has reached a preset first control start torque, such that the measured torque reaches a preset first set torque in a phased manner through repeated increases and decreases in torque, and blocking power supply to the motor when the measured torque reaches the first set torque, and a second tightening process of driving the motor at an initial output that is less than in the first tightening process, adjusting the output of the motor after the measured torque that is measured by the torque detector has reached a preset second control start torque, such that the measured torque reaches a preset second set torque in a phased manner through repeated increases and decreases in torque, and blocking power supply to the motor when the measured torque reaches the second set torque.

A vehicle tire change kit includes a hydraulic jack that has an input socket and a lifting plate. The lifting plate is raised or lowered when the input socket is rotated in a respective first direction or second direction to jack a vehicle. An impact driver is provided that has an output chuck which is matable to the input socket of the hydraulic jack for rotating the input socket in either the first direction or the second direction. A plurality of impact sockets is provided to engage lug nuts on a respective tire on the vehicle for removing the respective tire from the vehicle.
