Problems solved by technology
The non-hydraulic braking form is mainly divided into two types. One is the sled structure, which uses the sled instead of the wheel to realize the functions satisfied by the wheel. The unmanned helicopter stops on the deck, and since it has no hydraulic source to drive the wheel to brake, The conventional sled structure cannot be towed on the deck, and there are restrictions on the parking position of the unmanned helicopter; another form of non-hydraulic brakes is the wheel brake system, which adopts a wheel chock structure; however, the current wheel brake The system can only realize the horizontal plane locking function, and cannot be towed and moved

Embodiment Construction
[0019] This part is the embodiment of the present invention, which is used to explain and illustrate the technical solution of the present invention.
[0020] Disclosed is a left and right synchronous locking mechanism for aircraft wheels, which includes a left wheel locking mechanism and a right wheel locking mechanism.
[0021] Wherein, the locking mechanism of the left wheel includes a sliding sleeve 1, a moving plate 2, a pressing plate 3, a spring 4 and a pressing nut 6, and the moving plate 2 is fixedly connected with the left wheel so that the moving plate 2 and the left wheel are relatively stationary, The moving plate 2 extends into the sliding sleeve 1, one side of the moving plate 2 is the inner wall of the sliding sleeve 1, and the other side is the pressing plate 3; the other side of the pressing plate 3 is provided with a spring 4, and the other side of the spring 4 is provided There is a compression nut 6; the spring 4 is a disc spring; the lower end of the slid...

The invention discloses an airplane wheel left-right synchronous locking mechanism for aviation. The mechanism comprises a left airplane wheel locking mechanism and a right airplane wheel locking mechanism, the left airplane wheel locking mechanism comprises a sliding sleeve, a movable disc, a pressing disc, a spring and a pressing nut, the movable disc is fixedly connected with a left airplane wheel to enable the movable disc and the left airplane wheel to be relatively static, the movable disc extends into the sliding sleeve, one side of the movable disc is the inner wall of the sliding sleeve, and the other side is the pressing disc; a spring is arranged on the other side of the pressing disc, and a pressing nut is arranged on the other side of the spring; and the right airplane wheel locking mechanism and the left airplane wheel locking mechanism are consistent in structure. The mechanism is simple in structure, convenient and fast to mount and dismount and capable of being repeatedly used; a problem that the airplane wheel is locked under the condition that there is no hydraulic drive is solved; under the condition that the airplane wheels are not rotated, the problem of synchronous locking of the left and right airplane wheels is solved; and the left airplane wheel and the right airplane wheel can be synchronously locked and unlocked without being influenced by positionsand angles.
Description
technical field [0001] The invention belongs to the technical field of brake locking mechanisms, and relates to a locking mechanism for mechanically locking aircraft wheels, in particular to a left and right synchronous locking mechanism for aircraft wheels. Background technique [0002] The wheel brake system of aviation helicopters is mainly divided into two types: hydraulic brake and non-hydraulic brake. The hydraulic brake mainly uses the hydraulic oil in the pipeline to push the brake disc and disc by the brake pressure to eliminate the brake gap, so that the brake disc, Friction is generated between the plates to achieve wheel locking. The non-hydraulic braking form is mainly divided into two types. One is the sled structure, which uses the sled instead of the wheel to realize the functions satisfied by the wheel. The unmanned helicopter stops on the deck, and since it has no hydraulic source to drive the wheel to brake, The conventional sled structure cannot be towed...
