A propulsion system may include an electric machine and a gear set that may be operatively connected with the electric machine. A crank shaft may extend through the electric machine and the gear set. A battery array may be disposed around the electric machine and the gear set.

Integrated mid drive electric bicycle propulsion system

An electric cycle with a frame that may include a tube and an opening. The tube may extend from a first end to a second end and may define a tube interior volume in fluid communication with the opening. An electric power unit may be mounted to the frame proximal the second end of the tube and may have a cooling air inlet and an exhaust port. A cooling path may be defined through the tube interior volume and at least a portion of the electric power unit. The cooling path may be in fluid communication with the opening so that air may flow into the opening, through the tube, into the cooling air inlet and out of the exhaust port of the electric power unit.

Cooling method for E-bike power and energy systems

A number of variations may include an electric cycle powertrain having a first planetary gear set and a second planetary gear set, wherein the second planetary gear set is constructed and arranged to selectively overdrive a pedal cadence and wherein the first planetary gear set is constructed and arranged to selectively provide additional gear ratio for a motor.

Electric bike powertrain with dual planetary gear sets and ring gear pedal reaction torque measurement

A number of variations may include a knee airbag mounted on a dash panel.

Knee airbag for motor vehicle

An integrated airbag and heating, ventilation, and air conditioning (HVAC) assembly includes an airbag module and an HVAC unit. The airbag module includes an airbag housing and an inflatable bladder at least partially disposed in the airbag housing. The inflatable bladder is movable relative to the airbag housing between a stowed position and a deployed position. The HVAC unit includes an HVAC housing. The HVAC housing supports the airbag housing.

A method is disclosed for controlling a suspension corner connected to a road wheel in a vehicle's adjustable suspension system. The method includes monitoring operation of the vehicle, detecting an occurrence of a predetermined vehicle event, and detecting a road speed of the vehicle. The method also includes monitoring a ride height of the vehicle at the suspension corner. The vehicle ride height at the suspension corner is selected via a bladder arranged at the suspension corner. The bladder is characterized by a variable height and configured to pump a fluid in response to forces generated at the road wheel and hold a volume of the fluid. The method additionally includes selecting the ride height at the suspension corner in response to the detected occurrence of the predetermined vehicle event and the detected vehicle road speed by regulating the volume of the fluid being held by the bladder.

Control of adjustable ride height suspension

A vehicle is disclosed. A wall includes a first portion disposed adjacent to a first end, a second portion disposed adjacent to a second end and a middle portion disposed between the first and second portions. A panel includes a first panel portion disposed along the first portion, a second panel portion disposed along the second portion and a middle panel portion disposed along the middle portion. The panel extends outwardly away from the wall a distal surface to define a cavity. An airbag device is attached to the second portion and disposed inside the cavity. A beam is coupled to one of the first portion and the middle portion inside the cavity. The beam extends into the cavity from the first end of the wall along an axis such that the beam is spaced from the second panel portion and the second portion along the axis.

Vehicle and an instrument panel for the vehicle

A suspension system for a vehicle having a vehicle body and a road wheel includes a suspension corner connecting the road wheel to the vehicle body. The suspension corner maintains contact between the road wheel and a road surface. The suspension system includes a bladder arranged at the suspension corner for pumping a fluid in response to forces generated at the wheel and holding a volume of the fluid. The suspension system also includes an accumulator in fluid communication with the bladder for selectively accumulating the fluid pumped by and releasing the fluid to the bladder. The suspension system additionally includes a valve for selectively retaining the accumulated fluid in and releasing thereof from the accumulator. The height of the bladder varies in response to the volume of fluid being held by the bladder to set a ride height of the vehicle at the suspension corner.
