Abstract
A starter assembly is provided and includes a shaft to transmit rotation to a ring gear via a pinion and including a first helical spline with angling directed reversely with respect to a direction of the rotation and an elastic element anchored on the first helical spline to bias the pinion in an axial direction. The ring gear and the pinion include complementary teeth and the pinion defines a bore with a second helical spline to register with the first helical spline such that the pinion teeth are forwardly rotated into ring gear teeth engagement positions as the shaft moves axially relative to the pinion in the axial direction.
Claims21
A starter assembly, comprising:
- a pinion;
- an output shaft to transmit rotation to a drive assembly ring gear via the pinion and including a first helical spline with angling directed reversely with respect to a direction of the rotation;
- and
- an elastic element anchored on the first helical spline to bias the pinion in an axial direction,
- the ring gear and the pinion including complementary teeth, and
- the pinion defining a bore with a second helical spline to register with the first helical spline such that the pinion teeth are forwardly rotated into respective engagement positions with the ring gear teeth as the output shaft and the first helical spline move axially relative to the pinion in the axial direction.
A starter assembly including a driveshaft rotatable in a rotation direction and comprising:
- a pinion;
- an output shaft to transmit driveshaft rotation to a drive assembly ring gear via the pinion and including a first helical spline with angling directed reversely with respect to a direction of the rotation;
- and
- a bias assembly including a stopper and an elastic element anchored on the first helical spline to bias the pinion toward the stopper,
- the ring gear and the pinion including complementary teeth, and
- the pinion defining a bore with a second helical spline to register with the first helical spline such that the pinion teeth are forwardly rotated into respective engagement positions with the ring gear teeth as the output shaft and the first helical spline move axially relative to the pinion against the bias.
