Description
Technical field:
The present invention relates to a kind of self-propelled vehicle that is used to drag farm implements such as whole ground or sowing, especially relate to a kind of direct drive wheel type farm truck.
Background technology:
Known self-propelled vehicle or farm vehicle generally include the front-wheel and the trailing wheel that can freely turn to or rotate, engine installation and the driving device that is connected with the mouth of engine installation are installed on the main body of vehicle body, and the deceleration of driving device by support and drive disk assembly and actuating device or final hunting gear are connected and drive hind axle and/or front wheel spindle again, move in turn with final realization of mode that cardan shaft rotates.Because wheel shaft is less with respect to the diameter of wheel, under identical external force effect, promptly directly act on axle or the wheel with identical power, for the rotating torque of wheel, its difference is very big, so, the self-propelled vehicle of known structure, particularly farm vehicle are not laborsaving, waste energy, and, cause its volume to increase because parts such as engine installation and driving device are all installed on the car body.
Known self-propelled vehicle or Agricultural automotive vehicle are except that being not enough to of above-mentioned driven member, also there is the problem turn to aspect such as displacement, designing requirement according to car, if engine installation and driving device, and actuating device is installed on the vehicle body with other auxiliary device, its vehicle body must have crash-resistant unmodifiable structure, and needing enough big parts, supports the vehicle body of this structure, and between big parts, should reach tight and crash-resistant cooperation, for this reason, car for identical horsepower output, the car of above-mentioned drive axle structures has big weight, brings certain difficulty to steering hardware, and being equipped with by mechanical power usually provides steering effort, further improve cost of manufacture, and be difficult for making the car body miniaturization.Simultaneously, the scantling of structure of car body is malleable not also, has only by the mode that changes trailing farm implements size and realizes dragging.
As one of designer of the present invention applicant, at a utility model patent of first to file, its notification number is CN2422797, and the agricultural machinery and implement that name is called " Large round wheel tractor " are exactly to want to adopt the mode of direct drive wheel to overcome above-mentioned defective.The disclosed technical scheme of these agricultural machinery and implement is internal support plate and the supporting wheel frame that has the composite set of interior driving engine of the ring wheel of being installed in and retarder and be used to support these devices, and the transmission gear that is arranged on ring wheel internal tooth that wheel installs on the internal diameter and is meshed with ring wheel internal tooth in described the wheel, in wheel, the lower and upper cross-member that is used for fixing the manual steering bar is installed also, and directly rotates this ring wheel and realize that car body turns to by being arranged on deflecting bar in half arc support.Because this ring wheel must be connected with vehicle body or other parts at rear portion by described half arc support, if and two bow spacings that constitute half arc support are provided with wide, not only influence the attractive in appearance of profile, but also can increase anterior weight, bring certain difficulty also for the design at rear portion from the angle of balance, if the spacing of two bows is narrow, its angle that turns to is very limited; This patent does not provide the concrete structure of parts such as vehicle body simultaneously, structure according to traditional farm vehicle, its vehicle body can not arbitrarily be adjusted especially for the vehicle body position that agricultural machinery and implement such as plough are installed, and has limited its range of use and has made troubles for the operation that agricultural machinery and implement such as plough are installed thereby give; In addition, owing to adopt the structure of driving wheel double as wheel flutter can increase the burden that turns to.
