A vibration detection device for detecting vibration of a cartridge including a bearing housing that accommodates a rotor coupling a wheel and a rotor shaft, and a bearing rotatably supporting the rotor, the bearing housing including a lubricant-oil passage port for allowing lubricant oil to pass through an interior of the bearing housing, includes: a sensor mount attached to an oil-flow-passage forming member configured to be capable of connecting to and separating from the bearing housing, the oil-flow-passage forming member including, inside thereof, an oil flow passage through which one of lubricant oil to be supplied to the interior of the bearing housing via the lubricant-oil passage port or lubricant oil discharged from the interior of the bearing housing via the lubricant-oil passage port flows; a vibration sensor disposed on the sensor mount; and a vibration transmission leg portion connected to the sensor mount and configured to be in contact with the bearing housing in a state where the oil-flow-passage forming member is connected to the bearing housing.

A suspension system for a vehicle and method for operating the same includes a shock absorber housing having a longitudinal axis, a spring disposed around the shock absorber housing, a retainer collar disposed around the shock absorber housing and an actuator engaged to the retainer collar. The actuator moves at least a portion of the retainer collar to move the spring in a direction corresponding the longitudinal axis. A switch generates a ride height position signal. A controller is coupled to the actuator and the switch. The controller controls a position of the actuator in response to the ride height position signal.

A liquid gas supporting shock absorber. An oil path of the liquid gas supporting shock absorber, mainly composed of a liquid gas accumulator (4) and a single-acting hydraulic cylinder (7), is divided into a liquid inlet oil path (9) flowing into the single-acting hydraulic cylinder (7) and a liquid outlet oil path (6) flowing out of the single-acting hydraulic cylinder (7). A supporting force value of the liquid gas supporting shock absorber on an item supported thereby is measured using a force measuring element. A control component (1) compares the supporting force value to a set force value or a gravity value of the item supported by the supporting shock absorber, and the damping of the liquid inlet oil path (9) and the liquid outlet oil path (6) of the liquid gas supporting shock absorber is controlled by means of a mechanical, hydraulic or electronic control mode according to the result of the comparison, so as to adjust the supporting force value of the supporting shock absorber, so that the supporting force value of the supporting shock absorber is equal to or close to the set force value or the gravity value of the item supported by the supporting shock absorber.

A combination vehicle tire sensor assembly and in-tire wheel balancer is adapted for residing inside a pneumatic tire mounted on a wheel rim of a motor vehicle. The combination includes a flexible mounting cable secured to the sensor assembly, and adapted for extending circumferentially within an annular space formed between the tire and wheel rim. A counterweight is secured to the mounting cable inside the pneumatic tire a spaced distance from the sensor assembly. A substantially hollow balancer belt resides inside the pneumatic tire adjacent the sensor assembly and counterweight, and defines a circumferentially-extending exterior groove designed for receiving and locating the mounting cable, and a circumferentially-extending interior cavity adapted for loosely containing a wheel-balancing medium.

A modular electronic damping control system is described and includes a damping component located at a vehicle suspension location. The modular electronic damping control system also includes a control system configured to control the damping component, and determine the type of damping component present. Also, the control system is configured to automatically tune a vehicle's suspension based on the type of damping component present, and automatically monitor the damping component and determine when a change has been made to the damping component so that the control system can then automatically re-tune the vehicle's suspension based on the change to the damping component.

A dynamic balancing assembly for a laundry apparatus includes a control unit, one or more counterweight devices, and one or more clocksprings. The one or more counterweight devices are configured to be orbited about a primary rotation axis of the laundry apparatus to counteract a load imbalance in a drum of the laundry apparatus. The one or more clocksprings communicatively couple each of the one or more counterweight devices to the control unit.

A method for determining a detection sensitivity of a rotation rate sensor, the rotation rate sensor including an oscillatory system. A first quadrature signal of the oscillatory system is determined in a first step. A controlled change of a transfer function of the oscillatory system takes place in a second step. A second quadrature signal of the oscillatory system is determined in a third step. The detection sensitivity is determined in a fourth step on the basis of the first and second quadrature signal. A method is also described for determining a detection sensitivity of a rotation rate sensor, the rotation rate sensor including one first oscillatory system and one second oscillatory system.

A modular electronic damping control system is described and includes a damping component located at a vehicle suspension location.

Example aspects relate to a shock absorber with a position sensor, and a method to produce it. The shock absorber comprises a first and second damper part, which are arranged movable relative to each other in a longitudinal direction L. A position sensor is arranged to detect the relative position of the first damper part to the second damper part, and comprises an index element on the first damper part as well as an electric detection circuit for detecting the position of the index element. A flexible sleeve is at least partially arranged around the first and/or the second damper part and fixed relative to the second damper part. To enable a particularly simple design, the detection circuit is attached to the flexible sleeve.

A suspension system for a vehicle and method for operating the same includes a shock absorber housing having a longitudinal axis, a spring disposed around the shock absorber housing and a retainer collar disposed around the shock absorber housing. An actuator coupled to the retainer housing moves at least a portion of the retainer housing to move the spring in a direction corresponding the longitudinal axis.
