Example Embodiment

[0031] The inventive design of the landing gear will be described in detail below with reference to the accompanying drawings.

[0032] like Figure 1-3 As shown, the electric motorcycle / two-wheel electric vehicle landing gear with failsafe function of the present invention includes a landing gear main support body 1 , a push-pull connection body 2 , a motor screw drive body 3 and a failure pull rod device 4 . The landing gear is designed to be mounted on the frame 5 . The motor screw drive body 3 converts the motor rotational force into a linear force, and is connected with the push-pull force connecting body 2; the push-pull force connecting body 2 is hinged with the main support body 1 of the landing gear to transmit the push-pull force of the motor screw drive body To the main support body 1 of the landing gear, drive the main support body 1 of the landing gear to reciprocate to complete the opening and retraction of the landing gear. The main support body 1 of the landi...

Abstract

The invention relates to an electric motorcycle/two-wheel electric vehicle undercarriage with a failure protection function. The undercarriage comprises an undercarriage main supporting body, a push-pull force connection body, a motor lead screw driving body and a failure pull rod device. According to the undercarriage, a motor push rod is used as a driving mode to push an undercarriage supportingrod to descend, a sleeve and a return spring which are innovatively designed are arranged between the motor driving push rod and the undercarriage supporting rod to achieve fast withdrawal of the undercarriage, and meanwhile the failure protection difficulty can be lowered. According to the undercarriage, by designing the failure pull rod device, under the condition that a motor/the motor drivingbody fails, the upward pull force of a lever mechanism drives a cable to complete the descending process of the undercarriage, the failure protection difficulty is lowered, and meanwhile the possibility of continuous driving of vehicles is guaranteed.

Description

technical field [0001] The invention relates to a landing gear with fail-safe function, which is especially applied to two-wheeled electric vehicles and electric motorcycles. Background technique [0002] Aircraft landing gear is a component used to support the weight of the aircraft and absorb impact energy. It can withstand gravity when the aircraft is parked, taxiing, takeoff and landing on the ground, absorb bump energy when the aircraft lands and collides with the ground, and provide braking during taxiing and taxiing. to move and control the aircraft. With the development of electric motorcycles and two-wheeled electric vehicles, their load capacity tends to increase. When the vehicle is parked, it needs to provide greater support. In addition, it is necessary to ensure the stability of the braking and starting stages. Two-wheeled electric vehicles also have requirements for the application of landing gear, and require simple principles and functions such as failure p...
