Description

Wheel self aligning all terrain vehicle chassis
Technical field:
The present invention relates to field of automobile, particularly relate to a kind of wheel self aligning all terrain vehicle chassis.
Background technology:
The traveling comfort taken more and more focused on by modern automobile, so that the traveling comfort of car is often classified as the important criterion that water buys by customer.Particularly for cross-country car, when passing through high mountain, valley, desert, rainforest area, if travelled on the road surface that difference of height is especially big, wheel can because skidding by heavy inequality, even unsettled, thus reduce the propelling thrust of wheel, even lose propelling thrust, greatly reduce the carrying capacity of vehicle, and navigating mate and passenger's sensation are jolted with uncomfortable very much.For improving the problem affecting vehicle performance because of Uneven road, suspension serves key role.
Suspension is the general name of all force transmission connections between the vehicle frame of automobile and vehicle bridge or wheel, its effect transmits the power that acts between wheel and vehicle frame and power is turned round, and buffering is passed to the impulsive force of vehicle frame or vehicle body by uneven road surface, and the vibration caused thus that decays, to ensure that automobile can be put down, " page ground travels.
Suspension is divided into stand alone type to hang and dependent formula hangs.Wherein, the wheel that dependent hangs is contained in the two ends of an overall axletree, when a sidecar wheel running is beated, will affect opposite side wheel and also beat accordingly, make whole body vibrations or inclination.
The axletree that stand alone type hangs is divided into two sections, often only give wheel coil spring to be arranged on independently below vehicle frame, when a sidecar wheel is beated, another side wheel is not involved, the vibration of vehicle body artificially reduces, car comfort is also able to very large lifting, and existing cross-country car uses stand alone type to hang, to overcome the adverse effect that Uneven road brings mostly.
But the cross country chassis of this kind of structure still has certain limitation, can only eliminate the sense of jolting when road surface difference of height is not very large, vehicle obstacle climbing ability neither be very high.And during vehicle conduct in the wild, often can run into the larger situation of road surface height margin, vehicle sense of jolting is still very strong, and vehicle body swing amplitude is still very large, and even vehicle cannot at all cannot clear an obstacle.
Summary of the invention:
Technical matters to be solved by this invention is the defect overcoming prior art, provides a kind of wheel self aligning all terrain vehicle chassis, to overcome the limitation of current cross-country car damping performance, improves overall obstacle climbing ability and the comfort level of cross-country car.
Technical matters to be solved by this invention realizes by the following technical solutions.
A kind of wheel self aligning all terrain vehicle chassis, comprise the spine bridge of bearing vehicle body, it is characterized in that: spine bridge half front axle is installed in described spine bridge front end, spine bridge half front axle front end connects propons rocking carrier, described spine bridge half front axle rear end connects front gear conversion regulator, semiaxis after described spine bridge rear end installation spine bridge, the later half shaft rear end of spine bridge connects back axle rocking carrier, after described spine bridge, backgear conversion regulator is installed in semiaxis front end, described front gear conversion regulator regulates transaxle to be connected with between backgear conversion regulator by gear, described propons rocking carrier both sides connect car front-wheel, described back axle rocking carrier both sides connect back wheels of vehicle.
Anterior conversion regulating tooth wheels are installed in described front gear conversion regulator, rear portion conversion regulating tooth wheels are installed in described backgear conversion regulator.
Described front portion conversion regulating tooth wheels comprise the last gear of straight-though arrangement, the first two number gear, first three number gear, front No. four gears, the first five number gear and the first six number gear from left to right; Described rear portion conversion regulating tooth wheels comprise rear No. six gears of straight-though arrangement, rear No. five gears, rear No. four gears, rear No. three gears, rear No. two gears and a rear gear from left to right.
Described last gear, front No. four gears, the first five number gear, the first six number gear, rear No. six gears, rear No. five gears, rear No. four gears and a rear gear are same size gear, the first two number gear, first three number gear, rear No. three gears and rear No. two gears are same size gear, and described first three number gear is the half of front No. four gear sizes.
Between described last gear with rear No. six gears, the first six number gear all regulate transaxle to be connected by gear with between a rear gear.
Propons rocking carrier and back axle rocking carrier respectively with semiaxis after spine bridge half front axle and spine bridge for load-bearing fulcrum and wave fulcrum, when wheel rolled lower or higher uneven road surface, can drive propons rocking carrier and/or back axle rocking carrier respectively with semiaxis after spine bridge half front axle and/or spine bridge for fulcrum waves, spine bridge half front axle and semiaxis after spine bridge are cushioned by the front gear conversion regulator that is connected and backgear conversion regulator, are weakened rotation swinging driving, reach the object to car body damping.
When on the right side of car body or when left side wheel rolled lower or higher uneven road surface simultaneously, can car body be automatically regulated to balance.
Described back axle rocking carrier comprises the spindle nose be connected with semiaxis after spine bridge, the diff waving upper bracket, be fixed on spindle nose lower end being fixed on spindle nose upper end, also comprise the upper rocking carrier and lower rocking carrier that connect back wheels of vehicle, described upper rocking carrier is with to wave upper bracket hinged, described lower rocking carrier and diff hinged, described in wave linking springs bumper between upper bracket and lower rocking carrier.
Described propons rocking carrier is identical with back axle rocking carrier structure.
Compared with prior art, the present invention has following beneficial effect:
A kind of wheel self-align spine bridge cross country chassis that the present invention proposes, damping performance is good, and carrying capacity is strong, and when vehicle travels on the road surface that difference of height is especially big, every wheel can regulate height to adapt to the ground of difference of height injustice automatically.
And when vehicle travels on the road surface that difference of height is large, every wheel can not increase being weighed of self along with the rising of wheel when climbing eminence, thus making vehicle more easily strong on climbing crossing over blockage, greatly strengthen the carrying capacity of vehicle.
In addition, no matter which wheel raises or reduces vehicle in motion, the rising of vehicle body and reduction are that about the half of wheel rising or reduction, that is the vehicle of this structure alleviates half than existing vehicle in the degree of jolting, thus make long-duration driving more comfortable with the personnel taken.
