Parking system for hybrid vehicle
A parking system for a hybrid vehicle includes a transmission housing, a first motor section provided in the transmission housing, and mounted on an input shaft, a second motor section provided at the rear of the first motor section, and mounted on the input shaft, and a parking mechanism provided between the first motor section and the second motor section for selectively restraining a drive gear spline-coupled to the second motor section. The parking system for a hybrid vehicle can be reduced in overall size by improving the layout of the parking mechanism within the transmission with two motors and forming the parking gear integrally with the drive gear.
1. A parking system for a hybrid vehicle, the parking system comprising:
a transmission housing;
a first motor section provided in the transmission housing, and mounted on an input shaft;
a second motor section provided at a rear of the first motor section, and mounted on the input shaft; and
a parking mechanism provided between the first motor section and the second motor section for selectively restraining a drive gear spline-coupled to the second motor section.
2. The parking system of claim 1 , wherein the parking mechanism comprises:
a manual lever;
a detent lever coupled to the manual lever and selectively rotating with the manual lever;
a parking rod coupled to the detent lever and configured to move with the rotation of the detent lever in a longitudinal direction of the parking rod;
a parking rod cam provided on the parking rod;
a parking rod spring provided on the parking rod and elastically supporting the parking rod;
a parking gear integrally formed with the drive gear between the first motor section and the second motor section;
a sprag hinged to the transmission housing and engaged with the parking gear with a longitudinal movement of the parking rod cam; and
a sprag spring elastically supporting the sprag.
3. The parking system of claim 2 , wherein the parking gear is integrally formed on one surface of the drive gear facing the first motor section.
4. The parking system of claim 2 , wherein the parking rod is guided by a brake housing formed between the first and second motor sections within the transmission housing when moved by the rotation of the detent lever.
