Description
Technical field
The present invention relates to a kind of beach buggy, relate in particular to beach buggy two-wheeled and four-wheel drive device.
Background technology
At present, beach buggy on the market all is to drive front-wheel motion (front-wheel does not have direct power) in the majority with back-wheel drive.Two front-wheels of beach buggy are installed on the vehicle frame by suspension fork mechanism, and two trailing wheels are sleeved on separately the rear axle shaft.The power of beach buggy is provided by driving engine, the rear end of engine output shaft is connected with the front end of universal-joint splined shaft with the first universal-joint spline housing by adapter shaft, the rear end of universal-joint splined shaft is connected with the input shaft of rear drive case by the second universal-joint spline housing, two output sleeves of rear drive case are connected with two rear axle shafts respectively, the power of driving engine is successively by the first universal-joint spline housing, universal-joint splined shaft, the second universal-joint spline housing, rear drive case and rear axle shaft like this, the rotation of driving trailing wheel, the beach buggy car load travels forward or backward.Because beach buggy has only trailing wheel that propulsive effort is arranged, dynamic property is not strong, and crossing ability is relatively poor, when beach buggy is being climbed the very oblique operation that is difficult to when sloping; When beach buggy travelled in muddy or frost boiling highway section, wheel was got down hopeless in a quagmire easily or is difficult to advance because of skidding, and then problems such as flame-out occur.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of beach buggy two-wheeled and four-wheel drive device, so that beach buggy is selected two-wheel drive or four wheel drive as required, thus the dynamic property and the crossing ability of raising beach buggy.
Technical scheme of the present invention is as follows: a kind of beach buggy two-wheeled and four-wheel drive device, the rear end of engine output shaft is connected with two rear axle shafts by the back transmission device, its key is: the front end of described engine output shaft passes from the front end face of motor body, and the end joint connection by spline housing and front propeller shaft, the front end of this front propeller shaft is connected with the input main spindle multiple spline of before driving case, the output main shaft of described before driving case is provided with finishing bevel gear cuter, the input screw bevel gear engagement of this finishing bevel gear cuter and diff, two output sleeves of described diff are connected with two propons semiaxis respectively, and two propons semiaxis are arranged symmetrically in the both sides of diff; The input main shaft of described before driving case is provided with shape and the identical male splines of size with the output main shaft, and output main shaft male splines on the suit spline sleeve, the outside face of this spline sleeve has circular groove, the shift fork of one shifting fork mechanism snaps in this circular groove, and the handle of shifting fork mechanism is positioned at the outside of before driving case and hinged with the beach buggy vehicle frame.
It is mechanism that the present invention changes the mounting structure of beach buggy front-wheel into bridge by traditional suspension fork mechanism, so that accept the power of driving engine.At the propons bridge is to set up before driving case and front propeller shaft between mechanism and the driving engine, the input main shaft of before driving case is provided with shape and the identical male splines of size with the output main shaft, spline sleeve on the output main shaft male splines is controlled by shifting fork mechanism, under the drive of shifting fork mechanism, spline sleeve driving box is in the past exported main shaft to the slippage of input main shaft, make to export between main shaft and the input main shaft to engage or separation, beach buggy can select have only the drive form of trailing wheel participation or the drive form that front and back wheel participates in simultaneously according to road conditions like this.
During engine operation, the rear end of engine output shaft drives two rear axle shafts rotations by the back transmission device, rotates thereby drive trailing wheel among the present invention; The front end of engine output shaft drives the front propeller shaft rotation, front propeller shaft drives the before driving case input main shaft that is attached thereto again and rotates synchronously, when current driving box input main shaft is in released state with the output main shaft, the idle running of before driving case input main shaft, the output main shaft does not rotate, this moment, beach buggy adopted two back-wheel drives, was suitable in condition of road surface travels down preferably.When current driving box input main shaft is in engagement state with the output main shaft, the input main shaft drives the output main axis rotation by spline sleeve, the output main shaft drives two propons semiaxis rotations by diff again, thereby driving front-wheel rotates, this moment, the front and back wheel of beach buggy all had propulsive effort, strengthened the dynamic property of beach buggy so greatly, effectively improved the crossing ability of beach buggy, made that beach buggy reaches mire more greatly in the gradient, frost boiling all can be travelled on the highway section smoothly.
Front end at above-mentioned front propeller shaft is provided with the cydariform male splines, and this cydariform male splines stretches in the internal splined hole at before driving case input main shaft rear portion, and both splines connect.Front propeller shaft adopts the cydariform male splines to be connected with the female splines of before driving case input main shaft, reduced cooperation difficulty between the two, when even trickle change takes place owing to reasons such as welding deformations in the installation site of front propeller shaft and before driving case, also can be seated, thereby greatly reduce assembly difficulty and working strength of workers, effectively improved efficiency of assembling.Simultaneously, because importing with the before driving case, front propeller shaft adopt the cydariform male splines to cooperate between the main shaft with straight-tooth shape female splines, front propeller shaft can be done tubaeform rotation around the center of cydariform male splines in the process of transmission like this, and then prevented that effectively the female splines that centrifugal when rotation and before driving case are imported main shaft from bumping, eliminate abnormal sound, and ensured the reliability of transmission performance.
Be provided with spring in the internal splined hole of above-mentioned before driving case input main shaft, the rear end of this spring is stretched in the end face groove of front propeller shaft.Spring works to eliminate endplay between front propeller shaft and the before driving case input main shaft, with the reliability of further guarantee transmission.
Front end at above-mentioned before driving case input main shaft is provided with guidepost, and this guidepost stretches in the corresponding aperture of output main shaft, both free-running fits.Guidepost plays guiding, and it is easier that before driving case input main shaft is engaged with the output main shaft.
For simplified structure, be convenient to install and handle, above-mentioned shifting fork mechanism is made of shift fork, guide finger, connecting rod and handle, wherein guide finger is installed in the resigning hole on the before driving tank shell, the middle part kink of described shift fork is on guide finger, the inner of shift fork snaps in the circular groove of spline sleeve outside face, and stretch out outside the before driving tank shell outer end of shift fork, and is connected with the front end of connecting rod, the rear end of described connecting rod and the lower end of handle are hinged, and the middle part of handle is hinged on the beach buggy vehicle frame.
Beneficial effect: the present invention has novel, reasonable in design, characteristics such as enforcement is easy, applied range, it can make beach buggy select two-wheel drive or four wheel drive for use according to actual conditions, and easy switching between two-wheel drive and the four wheel drive, handle simple, thereby improved the power power and the crossing ability of beach buggy greatly.
