The front axle automatic meshing device is characterized by also comprising an automatic hub locking device composed of a shell, a base, a gear and a return spring, wherein the right end of the front axle half shaft is connected with the base by virtue of a spline, the outer wall of the gear is provided with a gear cam which can rotate and move in the cam slot of the base on the outer wall of the left end of the base, the outer wall of the middle part of the base is connected with the inner wall of the shell in a 'KAN' (a radical in Chinese characters) shape by virtue of the spline; the left end of the return spring props against between a stop washer and the inside wall of the shell; and the shell is fixed on the front wheel hub by a screw rod. The gear is provided with a gear stop block which can stretch into the groove of the knuckle. The device provided by the invention has the advantages that a purely mechanical automatic control mechanism is adopted, thus the control convenience and reliability of a four-wheel-drive system are improved, the fuel economy of a cross-country vehicle is improved, the whole vehicle is compact in arrangement, the weight is light and the like.
Description
Technical field
The present invention relates to automobile equipment, especially relate to a kind of 4 off-road wheels and drive the automatic geared assembly of car propons.
Background technology
Along with the development of automotive technology, the cross-country traveling ability of SUV car, fuel economy and control comfort are more and more valued by the people.At present, the wheel limit geared assembly of four-wheel drive vehicle is all Manual operation mechanism or electric operation mechanism, but in the time that SUV car travels under severe road surface or cross-country operating mode, due to Manual operation mechanism, the manual switching mechanical brake of automotive wrench could gear shift under chaufeur after need to stopping, and makes to handle very inconvenience; And electric operation mechanism is due to the reason such as electric drive power is inadequate or electronic operation is not in place and electronic component itself is unreliable, gear shift in time, reliability is poor.
Summary of the invention
The object of the present invention is to provide a kind of automatic controller that adopts pure machinery, promote comfort feature that four-wheel drive system handles and reliability, the fuel economy of raising cross-country car, quality is light, arrangement is compact 4 off-road wheels drive the automatic geared assembly of car propons.
The object of the present invention is achieved like this:
A kind of 4 off-road wheels drives the automatic geared assembly of car propons, comprise by front wheel hub, the motivation transfer motion part of steering swivel and front axle half shaft composition, tire is arranged on front wheel hub, the outer wall of steering swivel is arranged on the centre of front wheel hub by conical bearing, axle drive shaft and the front axle half shaft connected with engine power are connected, the left end of front axle half shaft is arranged on by coro bearng in the middle of the knuckle bores of steering swivel, feature is: also comprise by housing, base, the automatic hub mechanical brake that gear and pull back spring form, the right-hand member of front axle half shaft extend in the base aperture of base, link together by spline and base, on the left end outer wall of base, be processed with the base cam path of indent, gear is positioned over the left end of base, on the outer wall of gear, be processed with the cam rotating in can the base cam path on the left end outer wall of base, the male splines that can make axial motion on base is installed on the outer wall of the middle part of base, inwall at the housing of " Qian " shape has the female splines coordinating with male splines, base links together by male splines and housing female splines, the only packing ring that is fixed with annular on the outer wall of the middle part of base is fixed with annular back-up ring on the right-hand member outer wall of base, and the left end that is enclosed within the pull back spring on base right-hand member outer wall withstands on and stops on packing ring, and the right-hand member of pull back spring withstands on back-up ring, screw rod is fixed on housing on front wheel hub through housing side opening and front wheel hub side opening.
Lateral wall right-hand member at steering swivel is processed with steering swivel groove, is processed with and can extend into the gear stops playing the role of positioning in steering swivel groove on gear.
In the time that SUV car travels under the good operating mode in road surface, without four wheel drive, because base separates with housing, front-wheel (being front wheel hub) and motivation transfer motion part disconnect, and there is no circulating of power, thereby can be fuel-efficient and energy-conservation.When SUV car travel under severe road surface or cross-country operating mode, need to use four wheel drive time, when pilot control, need only part-time case is hung up to four wheel drive gear, axle drive shaft by the transmission of power of driving engine to front axle half shaft, front axle half shaft makes the base rotation of automatic hub mechanical brake, base is pressed to right back by the base cam path on base, base engages with housing automatically by spline, drives front wheel hub to rotate by housing, thereby drives front-wheel.Due to cam being installed on gear, gear is connected with steering swivel by gear stops, and gear does not rotate all the time.When release, part-time case does not have transmission of power to base, and base and housing do not have relative motion or movement tendency, and base is self-return under the effect of pull back spring.
Therefore, the present invention have advantages of adopt pure machinery automatic controller, promote comfort feature that four-wheel drive system handles and reliability, the fuel economy of raising cross-country car, arrangement compactness, quality light, realized structure lightweight requirements.
