Description

Preceding two-wheel car forward mounting leaning device

Technical field

The utility model relates to a kind of automobile front wheel leaning device, can prevent effectively that especially wheel is at the preceding two-wheel car forward mounting leaning device of turning and fall down when wet and slippery on the road surface.

Background technology

Along with the raising of people's living standard, the vehicle are also being updated and are being developed; Traditional many years ago foot-operated two-wheeled cycle is replaced by electronic two-wheeled, three-wheel and four-wheeled.Because the restriction of the factor of the energy, environmental protection, road and parking area, China can not the picture whole people of developed country all with automobile as the main vehicle, the thing followed is the fast development of battery-driven car and motor bike.Motor bike and battery-driven car be little to take up room, in light weight, easily park and moderate characteristics are subjected to liking of wage-earners.

But two-wheel car has a very big shortcoming: because the special construction of two-wheel car, the earth point of front-wheel when turning with the facade of vehicle frame not on same plane, the easy cunning fallen down on the higher and wet and slippery road surface of speed.Upright three-wheel, four-wheeled have centnifugal force when travelling on bend, and the people who allows custom ride two-wheel car does not feel like oneself.Recent years occurred the double front wheel car of multiple tilting-type, overcome the shortcoming of falling down easily, can ride as two-wheel car again, it is suitable with two-wheel car to take up room, with conspicuous characteristics, and energy-conserving and environment-protective are progressively enlarging market scope, enter common people house.

The utility model content

When turning or on the wet and slippery road surface, fall down and ride stable inadequately problem in order to overcome existing two-wheel car easily, the utility model provides a kind of preceding two-wheel car forward mounting leaning device, should use the forward mounting leaning device durable by preceding two-wheel car, simple in structure, manufacturing cost is lower, and it is comfortable to ride, light and flexible, wing drop was not easy to fall down when this car travelled when turning or on the wet and slippery road surface, and felt very comfortable in the process of riding, and brought great convenience for people's trip.

The technical scheme that its technical matters that solves the utility model adopts is: this preceding two-wheel car is provided with a barrel-contoured front fork tube with the forward mounting leaning device, be provided with steering shaft in the front fork tube, the front of front fork tube is connected with permanent seat, permanent seat is provided with cooresponding upper shaft hole and lower shaft hole up and down, the upper shaft hole coupling is provided with jointed shaft, the both sides of last jointed shaft are connected with coaxial last left cantilever and last right cantilever respectively, the lower shaft hole coupling is provided with down jointed shaft, the both sides of following jointed shaft are connected with coaxial bottom left cantilever and bottom right cantilever respectively, go up left cantilever and last right cantilever and upwards be respectively equipped with left damping arm and right damping arm, be provided with bumper between left damping arm and the right damping arm; Go up right cantilever and bottom right cantilever and be connected respectively to right ball-joint I and the right ball-joint II that hangs of hanging, the right ball-joint I that hangs is connected with the steering swivel I with the right ball-joint II that hangs simultaneously, go up left cantilever and bottom left cantilever and be connected respectively to left side suspension ball-joint I and the left ball-joint II that hangs, a left side hangs the ball-joint I and is connected with the steering swivel II simultaneously with left side suspension ball-joint II, the steering swivel I is connecting the wheel shaft of right wheel I, the steering swivel II is connecting the wheel shaft of left wheel II, steering swivel I and steering swivel II are respectively equipped with spindle arm I and spindle arm II, the lower end of steering shaft is extended with the spindle arm III rearwards, the spindle arm III links to each other with the spindle arm I by the Synchronous pull rod I, and the spindle arm III links to each other with the spindle arm II by the steering track rod II; Go up left cantilever, a left side hang ball-joint I, bottom left cantilever, a left side hang ball-joint II, steering swivel II and go up right cantilever, the right ball-joint I, bottom right cantilever, the right suspension between ball-joint II and the steering swivel I of hanging formed two quadrangles; When under the effect of steering shaft at steering handle during left-hand revolution, the wheel axle steer of steering shaft pulling spindle arm III, steering track rod II, spindle arm II, steering swivel II and left wheel, the spindle arm III promotes the wheel axle steer of Synchronous pull rod I, spindle arm I, steering swivel I and right wheel simultaneously in the counterclockwise direction, thereby realizes easily turning to synchronously; Human body drives vehicle frame (containing front fork tube) and permanent seat tilts, and goes up jointed shaft and following jointed shaft horizontal displacement thereby drive, and then drives the cantilever dislocation, steering swivel I and steering swivel II are tilted, the final tilting of wheels that drives and turns to cooperation, realizes that tiltable freely rides; Bumper is used to support the antagonistic force that ground gives wheel, and it passes to bumper by wheel, steering swivel, suspension ball-joint, cantilever, jointed shaft; Simultaneously, bumper also can alleviate or offset the vibrations that ground does not pass to vehicle frame at ordinary times, make ride comfortable.

The beneficial effects of the utility model are that this preceding two-wheel car is simple in structure with the forward mounting leaning device, low cost of manufacture.With three-wheel and four-wheeled light and flexible that this mechanism makes, it is comfortable to ride, and wing drop when travelling on turning or wet and slippery road surface is not easy to fall down, and riding safety is comfortable, has brought facility for people's trip.
