Quick release telescoping and swiveling hitch assembly
A quick release assembly for remotely actuating operative disconnection between vehicles by decoupling a hitch assembly having a telescopic and swiveling probe assembly carried in a housing assembly and mounted on the towed vehicle. In one embodiment, the release assembly includes an actuator remotely controlled from the towing vehicle that releases the components retaining the probe assembly in the housing. In another embodiment, an actuator remotely controlled from the towing vehicle decouples the entire hitch assembly from the associated vehicle. In both instances, the towing vehicle may resume movement clear of the towing vehicle. Thereafter, the probe assembly and/or the hitch assembly may be recoupled for subsequent use.
1. A hitch assembly for towing vehicles, comprising:
a probe assembly;
a housing assembly configured to receive the probe assembly therewithin;
a lock assembly operably associated with the housing assembly that releasably locks the probe assembly within the housing assembly, wherein the lock assembly is movable between locked and unlocked positions;
an actuator operably associated with the lock assembly that, when activated, moves the lock assembly from a locked position to an unlocked position such that the probe assembly can be released from the housing assembly; and
a device remotely located relative to the actuator for activating the actuator.
2. The hitch assembly of claim 1 , wherein the device is located within a towing vehicle.
3. The hitch assembly of claim 1 , wherein the device is located within a cab of a towing vehicle.
4. The hitch assembly of claim 1 , wherein the device comprises an electrical switch.
5. The hitch assembly of claim 1 , wherein the actuator is a pneumatic actuator.
6. The hitch assembly of claim 1 , wherein the actuator is an electromechanical actuator.
7. The hitch assembly of claim 1 , wherein the lock assembly comprises a lock block having a bore, and a lock pin slidably supported within the lock block bore.
8. The hitch assembly of claim 7 , wherein the lock block bore is substantially vertical.
9. The hitch assembly of claim 7 , further comprising a spring configured to urge the lock pin toward a locked position.
10. The hitch assembly of claim 7 , wherein the actuator comprises a motor having an output shaft operably coupled to a latching plate, wherein rotation of the output shaft causes the latching plate to move the lock pin from a locked position to an unlocked position.
11. A hitch assembly for towing vehicles, comprising:
a probe assembly;
a housing assembly configured to receive the probe assembly therewithin;
a lock assembly operably associated with the housing assembly that releasably locks the probe assembly within the housing assembly, wherein the lock assembly comprises a lock block having a bore, and a lock pin slidably supported within the lock block bore and movable between locked and unlocked positions;
a motor having an output shaft operably coupled to a latching plate, wherein rotation of the output shaft causes the latching plate to move the lock pin from a locked position to an unlocked position such that the probe assembly can be released from the housing assembly; and
an electrical switch remotely located with a cab of a towing vehicle for activating the motor.
12. The hitch assembly of claim 11 , further comprising a spring configured to urge the lock pin toward the locked position.
13. The hitch assembly of claim 11 , wherein the lock block bore is substantially vertical.
