Background technology
Present four-wheel electric cross-country car has only the trailing wheel two-wheel drive, and suspension is dependent suspension, when vehicle on bad road, no road and soft surface, for example soft soil, desert, snowfield, marsh etc., or the part wheel is got down hopeless in a quagmire when producing idle running, its crossing ability is just very poor, even can't move.Open-air road surface mostly is ups and downs, and the shock and vibration meeting that the vehicle of dependent suspension produces in the process of moving allows the people feel uncomfortable, fatigue or damage goods.
The utility model content
In order to overcome crossing ability, the ride comfort deficiency that existing four-wheel electric motor car travels, the utility model provides a kind of electronic cross-country car that can be exchanged into four wheel drive, this battery-driven car can not only be with certain speed by bad road, no road and soft surface, for example soft soil, desert, snowfield, marsh etc., and when ups and downs road traveling, its traveling comfort, stationarity improve greatly.
Further purpose of the present utility model provides a kind of preceding driving device of electronic cross-country car of four wheel drive, the ball car that uses this device uses the back two-wheel drive when not only can be on the road surface good, and four wheel drive before and after when condition of road surface is bad, switching to, for example, on sleet sky and rocky stone road surface, improve the through performance of travelling of vehicle.And its front overhang is an independent suspension, and when ups and downs road traveling, its traveling comfort, ride comfort improve greatly.
The technical scheme that its technical matters that solves the utility model adopts is:
Can be exchanged into the electronic cross-country car of four wheel drive, comprise the gear case of vehicle body, drive axle, inside and outside constant speed ball cage universal-joint, axle drive shaft, motor and wheel thereof, its special character is: set up the preceding driving device that comprises the Drive-Axle Gears case at the propons of described car body, and by the described preceding driving device of switchable 4 wheel driven change-over swith control, described preceding driving device drives front-wheel.
According to the utility model, its special character is: driving device is the Drive-Axle Gears case by propons before described, install inside and outside constant speed ball cage universal-joint and hub in addition additional, and connect on vehicle body, constitute independent suspension by steering swivel, coil spring damper, lower cross arm.
According to the utility model, its special character is: motor is installed on the Drive-Axle Gears case, its driving torque slows down and differential through gear case, rotate by inside and outside constant speed ball cage universal-joint, axle drive shaft driven wheel hub unit, hub is driven by steering swivel in rotation and the helical spring shock absorber of strip winding rotates, and realizes turning to function simultaneously.
According to the utility model, its special character is: dust boot is arranged on the inside and outside constant speed ball cage universal-joint, prevents that foreign matters such as dust, silt, water from entering.
Owing to the utility model has adopted technique scheme, thus can be according to condition of road surface, the control motor rotates, and by the described preceding driving device of switchable 4 wheel driven change-over swith control, described preceding driving device drives front-wheel and rotates.The motor output torque slowed down by the Drive-Axle Gears case and differential pass in constant speed ball cage universal-joint, axle drive shaft, drives the rotation of outer constant speed ball cage universal-joint and hub, realize forerunner's function.Connect on vehicle body by steering swivel, coil spring damper, lower cross arm simultaneously, realize the function of independent suspension.Because motor is installed on the Drive-Axle Gears case, its driving torque slows down and differential through gear case, rotate by interior constant speed ball cage universal-joint, axle drive shaft, outer constant speed ball cage universal-joint driven wheel hub unit, hub is driven and can also be rotated by the helical spring shock absorber of strip winding by steering swivel in rotation, realizes turning to function simultaneously.
The beneficial effects of the utility model are:
The electronic cross-country car that can be exchanged into four wheel drive uses the back two-wheel drive when not only can be on the road surface good, and four wheel drive before and after when condition of road surface is bad, switching to, for example, road surfaces such as soft soil, desert, snowfield, marsh, avoid tyre skidding, improve the through performance of travelling of vehicle.And the shock and vibration of travelling and being produced when ups and downs road surface absorb through coil spring damper, and its traveling comfort, ride comfort improve greatly.
