Description
Technical field
the present invention relates to a kind of automobile front wheel leaning device, two-wheel car forward mounting leaning device before especially can effectively preventing wheel from falling down when turning and road surface slippery situation.
Background technology
along with the raising of people's living standard, the vehicles are also being updated and are being developed; Foot-operated two-wheeled cycle traditional many years ago by electronic two-wheeled, three-wheel and carriage replace.Due to the restriction of the factor of the energy, environmental protection, road and parking area, China can not to the whole people as developed country all using automobile as main traffic instrument, and the thing followed is the fast development of electric motor car and motorcycle.Motorcycle and electric motor car with take up room little, lightweight, easily to park and the feature of moderate cost is subject to liking of wage-earners.
but two wheeler has a very large shortcoming: due to the special construction of two wheeler, the earth point of front-wheel when turning with the facade of vehicle frame not in same plane, in speed, higher and wet-skid road surface is easily slided and falls down.Upright three-wheel, carriage have centrifugal force when travelling on bend, and the people allowing custom ride two-wheel car does not feel like oneself.Occurred the two front wheels car of multiple tilting-type recent years, overcome the shortcoming of easily falling down, can ride again as two wheeler, take up room suitable with two wheeler, with conspicuous characteristics, energy-conserving and environment-protective, progressively expand market scope, enter common people house.
Summary of the invention
easily fall down when turning or on wet-skid road surface to overcome existing two wheeler and ride problem stable not, the invention provides a kind of front two-wheel car forward mounting leaning device, this front two-wheel car forward mounting leaning device is durable, structure is simple, and manufacturing cost is lower, rides comfortable, light and flexible, when this car travels when turning or on wet-skid road surface, wing drop is not easy to fall down, and feels very stable, very comfortable in ride, brings great convenience to the trip of people.
the technical solution adopted for the present invention to solve the technical problems is: this front two-wheel car forward mounting leaning device is provided with the front fork tube of a tubular, steering spindle is provided with in front fork tube, holder is connected with before front fork tube, holder is provided with upper shaft hole corresponding up and down and lower shaft hole, upper shaft hole coupling is provided with jointed shaft, the both sides of upper jointed shaft are connected to coaxial upper left cantilever and upper right cantilever, lower shaft hole coupling is provided with lower jointed shaft, the both sides of lower jointed shaft are connected to coaxial bottom left cantilever and bottom right cantilever, upper left cantilever and upper right cantilever are upwards respectively equipped with left shock-absorbing arms and right shock-absorbing arms, damper is provided with between left shock-absorbing arms and right shock-absorbing arms, upper right cantilever and bottom right cantilever are connected respectively to right suspension ball-joint I and right suspension ball-joint II, right suspension ball-joint I is connected with knuckle I with right suspension ball-joint II simultaneously, upper left cantilever and bottom left cantilever are connected respectively to left suspension ball-joint I and left suspension ball-joint II, left suspension ball-joint I is connected with knuckle II with left suspension ball-joint II simultaneously, knuckle I is connected to the wheel shaft of right wheel I, knuckle II is connected to the wheel shaft of left wheel II, knuckle I and knuckle II are respectively equipped with steering arm I and steering arm II, Synchronous pull rod I is connected with between steering arm I and steering arm II, the lower end of steering spindle is extended with steering arm III rearwards, steering arm III is connected with steering arm II by steering linkage II, upper left cantilever, left suspension ball-joint I, bottom left cantilever, left suspension ball-joint II, knuckle II and upper right cantilever, right suspension ball-joint I, bottom right cantilever, between right suspension ball-joint II and knuckle I, constitute two quadrangles.When being rotated counterclockwise under the effect of steering spindle at steering handle, steering spindle pulls the wheel axle steer of steering arm III, steering linkage II, steering arm II, knuckle II and left wheel II, steering arm II promotes the wheel axle steer of Synchronous pull rod I, steering arm I, knuckle I and right wheel I simultaneously in the counterclockwise direction, thus realizes synchronous turning to easily; Human body drives vehicle frame (containing front fork tube) and holder to tilt, thus drives upper jointed shaft and lower jointed shaft horizontal displacement, and then drives cantilever dislocation, make knuckle I and knuckle II inclination, resulting belt motor car wheel tilts, and turns to cooperation, realizes tiltable and freely rides; Damper gives the reaction force of wheel for supporting ground, it passes to damper by wheel, knuckle, suspension ball-joint, cantilever, jointed shaft; Meanwhile, damper also can alleviate or offset the vibrations that ground does not pass to vehicle frame at ordinary times, makes to ride comfortable.
the invention has the beneficial effects as follows, this front two-wheel car forward mounting leaning device structure is simple, low cost of manufacture.The three-wheel made of this mechanism and carriage light and flexible, ride comfortable, and the wing drop when turning or wet-skid road surface travels, be not easy to fall down, riding safety is comfortable, brings facility to the trip of people.
