Engine cradle with deflector device
View Patent ↗An engine cradle mounting an engine in a vehicle has left and right side members spaced laterally apart on opposite sides of the engine, a rear cross member having right and left ends attached respectively to the left and right side members, and a front cross member having left and right ends attached respectively to the left and right side members. Body mounts are provided on the left and right ends of the front cross member for bolting the cradle to the vehicle body. Left and right deflector devices are mounted on the cradle, and each includes an impact receiving member that projects outwardly from the cradle to receive an impact load, and a brace member that extends between the cradle and the impact receiving member to brace the impact receiving member and provide a load path transferring the impact load into the cradle.
1. A cradle for mounting an engine in a vehicle having wheels located outboard of the cradle, said cradle comprising:
left and right side members spaced laterally apart from one another on opposite sides of the engine and inboard of the wheels;
a rear cross member having right and left ends attached respectively to the left and right side members;
a front cross member having left and right ends attached respectively to the left and right side members;
left and right vehicle body mounts provided respectively on the left and right ends of the front cross member for bolting to the vehicle body;
left and right deflector devices mounted respectively on the cradle adjacent the left and right body mounts and forwardly of the vehicle wheels, each of the left and right deflector devices including an impact receiving member that projects outwardly from the cradle to receive an impact load that is offset outboard from the body mounts, said impact receiving member projecting outwardly from the cradle and extending rearwardly at an angle of between 30 degrees and 45 degrees from the front cross member and having an end positioned adjacent or outboard of the vehicle wheel, and a brace member that extends between the cradle and the impact receiving member to brace the impact receiving member and provide a load path transferring the impact load into the cradle, one of said impact receiving member and said brace member having a semicircular receptacle that closely surrounds the body mount.
2. The cradle of claim 1 further comprising the impact receiving member being situated forwardly of the front cross member.
3. The cradle of claim 1 further comprising the impact receiving member being situated in general alignment with the front cross member and not forwardly of the front cross member.
4. The cradle of claim 1 further comprising each of the left and right deflector devices having the impact receiving member projecting outwardly from the cradle and mounted on the cradle by a side member extension projecting forward from the side member and a brace member extending between an outboard end of the impact receiving member and the end of the front cross member.
5. The cradle of claim 1 further comprising the impact receiving member being situated in general alignment with the front cross member and not forwardly of the front cross member and the brace member extending diagonally between the impact receiving member and the side member at a location rearward of the front cross member.
6. The cradle of claim 1 further comprising a supplemental brace acting to supplement the brace member by bracing the impact receiving member and assisting in transferring the impact load into the cradle.
7. The cradle of claim 1 further comprising the impact receiving member and the brace members being constructed of metal tubes that are welded or bolted to one another and to the cradle.
8. The cradle of claim 1 further comprising the impact receiving member having an outboard end that projects outwardly beyond the location front wheel.
9. A cradle for mounting an engine in a vehicle having wheels located outboard of the cradle, said cradle comprising:
left and right side members spaced laterally apart from one another on opposite sides of the engine and inboard of the wheels;
a rear cross member having right and left ends attached respectively to the left and right side members;
a front cross member having left and right ends attached respectively to the left and right side members;
left and right vehicle body mounts provided respectively on the left and right ends of the front cross member for bolting to the vehicle body;
left and right deflector devices mounted respectively on the cradle adjacent the left and right body mounts and forwardly of the vehicle wheels, each of the left and right deflector devices including a side member extension having a rear end attached to a front end of the side member, an impact receiving member having a forward end attached to a forward end of the side member extension, said impact receiving member projecting outwardly from the cradle and extending rearwardly at an angle of between 30 degrees and 45 degrees from the front cross member and having an end positioned adjacent or outboard of the vehicle wheel, and a brace member having an outboard end attached to the outboard end of the impact receiving member to brace the impact receiving member and provide a load path transferring the impact load into the cradle, and said brace member having a semicircular receptacle that partly surrounds the body mount and is attached to the respective end of the front cross member.
10. The cradle of claim 9 further comprising the brace member extending at an angle of 90 degrees with respect to the respective side member.
11. A cradle for mounting an engine in a vehicle having wheels located outboard of the cradle, said cradle comprising:
left and right side members spaced laterally apart from one another on opposite sides of the engine and inboard of the wheels;
a rear cross member having right and left ends attached respectively to the left and right side members;
a front cross member having left and right ends attached respectively to the left and right side members;
left and right vehicle body mounts provided respectively on the left and right ends of the front cross member for bolting to the vehicle body;
left and right deflector devices mounted respectively on the cradle adjacent the left and right body mounts and forwardly of the vehicle wheels, each of the left and right deflector devices including an impact receiving member that attaches to the respective end of the front cross member and extends outwardly therefrom at an angle of between 30 degrees and 45 degrees from the front cross member to end outboard beyond the vehicle wheel, and a brace member that extends between the side member of the cradle and the impact receiving member to brace the impact receiving member and provide a load path transferring the impact load into the cradle, and one or both of the impact receiving member and the brace member partly surrounding the vehicle body mount.
12. The cradle of claim 11 further comprising the impact receiving member having a semicircular receptacle provided therein for partly surrounding the vehicle body mount.
13. The cradle of claim 11 further comprising the brace member having an outboard end attached to the impact receiving member and an inboard end attached to the side member of the cradle rearwardly of the front cross member.
14. The cradle of claim 11 further comprising the impact receiving member being generally U-shaped including a forward leg for receiving the impact and a rearward leg attached to the side member and providing supplemental bracing of the impact receiving member.
15. The cradle of claim 14 further comprising the forward leg and rearward leg straddling the vehicle body mount and defining a semicircular receptacle that partly surrounds the vehicle body mount.
