REAR WHEEL STEERING APPARATUS FOR VEHICLE |
摘要 |
A rear wheel steering apparatus for a vehicle includes a housing including a cylinder portion and a casing, a linear motion mechanism including a nut member and a rod, the casing including at least one opening portion that opens in parallel to the rod and a communication hole provided separately from the opening portion, the casing positioned surrounding the rod extending from the cylinder portion and being fixed to the cylinder portion, a cover member joined to the casing to seal the opening portion of the casing, a controller housed in the casing, a power line and a signal line electrically connected to the controller in the casing, and a thermal shrinkage tube surrounding the power line and the signal line to retain thereof. The power line and the signal line are liquid-tightly supported in the communication hole of the casing via the thermal shrinkage tube. |

1. A rear wheel steering apparatus for a vehicle configured to be provided at a suspension mechanism supporting a rear wheel of the vehicle and for steering the rear wheel, the rear wheel steering apparatus comprising:
a housing configured to be connected to the suspension mechanism via a first connection member and a second connection member, the housing including a cylinder portion and a casing; an electric motor housed in the cylinder portion; a speed reduction mechanism housed in the cylinder portion and reducing speed of an output of the electric motor; a linear motion mechanism including a nut member rotatably connecting to the speed reduction mechanism and a rod threadingly engaged with the nut member and connecting to the second connection member, the linear motion mechanism converting a rotation of the nut member to a linear motion of the rod; the casing including at least one opening portion that opens in parallel to the rod and a communication hole provided separately from the opening portion, the casing positioned surrounding the rod extending from the cylinder portion and being fixed to the cylinder portion; a cover member joined to the casing to seal the opening portion of the casing; a controller housed in the casing and controlling an actuation of the electric motor; a power line and a signal line electrically connected to the controller in the casing; and a thermal shrinkage tube surrounding the power line and the signal line to retain thereof; wherein the power line and the signal line are liquid-tightly supported in the communication hole of the casing via the thermal shrinkage tube. |
