Problems solved by technology

[0006] With the acceleration of the popularization of two-wheeled electric vehicles, the increase in the luxury of vehicles and the increase in load have led to a tendency for vehicles to increase in weight. The way of relying on foot support cannot meet the needs of vehicle parking. The new two-wheeled electric vehicles are simple in structure, safe and reliable. , Landing gear with fail-safe function puts forward design requirements

Embodiment Construction

[0031] Below in conjunction with accompanying drawing, the inventive design of this landing gear is described in detail.

[0032] Such as Figure 1-3 As shown, the electric motorcycle / two-wheeled electric vehicle landing gear with fail-safe 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. This landing gear design is installed on the vehicle frame 5. The motor screw drive body 3 converts the motor rotation force into a linear force, and is connected with the push-pull force connector 2; the push-pull force connector 2 is hinged with the main support body 1 of the landing gear, and transmits the push-pull force of the motor screw drive body To the main support body 1 of the landing gear, the main support body 1 of the landing gear is driven to reciprocate to complete the opening and closing of the landing gear. The main supporting body 1 of the landing gear ...

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...
