A quarter car vehicle suspension including a wheel, a bearing having an axis of rotation, the piston rod axis aligned at an acute angle with respect to a spring axis of a coil spring of the suspension, and a spring seat integral with the bearing, wherein the bearing is located between the spring seat and the vehicle body, and wherein the axis or rotation of the bearing is substantially aligned with a spring axis and at an acute angle to the piston rod axis.

Strut assembly with integral bearing and spring seat

An electric motor inlcudes a slotted collar on the rotor and a temperature sensitive actuator with an attached pin effective when cold to move into an inserted position in which the pin engages the slotted collar to prevent rotor rotation, and when hot to move to a retracted position in which the pin is withdrawn from the collar to allow rotor rotation. The actuator comprises first and second springs having ends connected together and exerting opposing forces on each other, the second spring being made of a temperature sensitive memory metal so as to shorten and lengthen the actuator with changing temperature. The acutator is electrically conducting and inserted in series with the motor commutator, whereby armature current heats the actuator to move to the retracted position, and cessation of armature current allows it to cool and move to its inserted position.

A drive for a tandem windshield wiper system including a driver's side wiper blade and a passenger side wiper blade wherein the driver's primary vision area is wiped twice during each tandem stroke of the wiper blades. The drive includes a unidirectional electric motor with a crank arm, a rotatable drive plate connected to the passenger's side wiper blade, a driver's side crank arm connected to the driver's side wiper blade, a transverse drive link connected to the motor crank arm and linearly reciprocated thereby, linkage between the drive link and the drive plate operative to convert reciprocation of the drive link to angular oscillation of the drive plate and passenger side wiper blade, and a transverse operating link between the drive plate and the driver's side crank arm operative to transfer angular oscillation of the drive plate to the crank arm and driver's side wiper blade in tandem fashion.
