Abstract
The utility model provides a transmission means capable of causing a hand tractor to be driven by a rear wheel, which comprises a revolving shaft and a power output gear shaft. The utility model is characterized in that the revolving shaft is driven by the relative gear in a gearbox and drives the power output gear shaft, and the spline on the power output gear shaft drives the rear wheel of the hand tractor to move by connecting the relative transmission means outside the gearbox. The utility model not only keeps various working functions of the existing hand tractor in field, such as'worker-peasant'12 type which is capable of rotary cultivation, field ploughing, field raking, etc., but also increases the special function of the rear wheel drive to strengthen the adaptability greatly. When the hand tractor is used for short haul, the hand tractor can singly use the rear drive to increase the adhesive force of the rear wheel to the ground, thereby, the traction force of the tractor is reinforced, the oil consumption is reduced, and the driving of the tractor is safer. Under the condition of steep gradient and slippery road, the front wheel and the rear wheel are synchronously driven to improve passability, so the utility model is particularly adapted to the use under the condition of village with poor road surface.
Description
Technical field
The utility model relates to a kind of walker tractor parts, specifically a kind of driving device that makes the walker tractor back-wheel drive.
Background technology
The walker tractor that China produces use at present mostly is a f-w-d, " workers and peasants " 12 type walker tractors of producing as Nanning Walking Tractor Factory, Guangxi etc., the power of diesel engine output drives two front-wheels through power-transfer clutch, change speed gear box and steering clutch, trailing wheel is a flower wheel, do not have propulsive effort, goods is mainly by the trailing wheel load-bearing when short-distance transport.Little because of body deadweights such as the anterior driving engines of walker tractor, front-wheel is little to ground-surface adhesive ability, can not produce bigger tractive force, particularly is easy to skid and can not walks under the steep situation in high road, slope, rural area.Owing to only have the walker tractor of f-w-d when short-distance transport, to have all deficiencies, can not satisfy the needs of the current rural economic development of China.
Summary of the invention
The purpose of this utility model provides a kind of driving device that makes the walker tractor back-wheel drive.
For achieving the above object, the utility model utilizes two cone gear constant-meshes to rotate, and the performance that can change the transmission direction of power realizes the rear drive of walker tractor.Concrete grammar is: tapered gear, other end being housed to one one, the turning cylinder of round gear and one one are housed is the rear drive power output gear axle of spline for tapered gear other end, be combined into a kind of driving device (Fig. 1) that makes the walker tractor back-wheel drive, two cone gear constant-meshes in this device.Like this, as long as need are increased the traction frame of the walker tractor (as " workers and peasants " 12 types of Nanning Walking Tractor Factory, Guangxi's production) of back-wheel drive function, the change speed gear box bonnet takes off, install this rear drive driving device, make " workers and peasants " 12 types " change speed gear box internally-powered output shaft---the transmission gear on the 2nd becomes the normally engaged driving gear of round gear on this device turning cylinder; the cone gear on the rear drive shaft just becomes the normally engaged driving gear of the upper conical gear of power output gear axle; like this spline on the power output gear axle by with outer relevant driving device such as the universal drive festival of change speed gear box; transmission shaft; connections such as differential box back axle can drive the trac. trailing wheel when needed and walk.
The utility model had both kept former walker tractor front driving device and had carried out the every function of farm work, increased rear drive equipment again, when shipping goods, only use rear drive, to increase trailing wheel to ground-surface adhesive ability, the tractive force of trac. strengthened, reduce consumption of fuel, exercise safer, but four-wheel drives simultaneously under the steep slope and slippery path condition, improves crossing ability, is particularly suitable for using under the bad situation of rural area road conditions.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1: a kind of driving device organigram that makes the walker tractor back-wheel drive.
Fig. 2: turning cylinder scheme drawing.
Fig. 3: rear drive power output gear axle scheme drawing.
(1) turning cylinder among the figure; (2) circular gear on the turning cylinder; (3) cone gear on the turning cylinder; (4) rear drive power output gear axle; (5) cone gear on the rear drive power output gear axle; (6) spline on the rear drive power output gear axle; (7) drive housing; (8) bearing.
The specific embodiment
In Fig. 1, the circular gear (2) on the turning cylinder (1) is the passive constant mesh gear of associated transfer gear in the walker tractor change speed gear box that need to increase the back-wheel drive function (workers and peasants that produce as Nanning Walking Tractor Factory, Guangxi " 12 types " change speed gear box internally-powered output shaft---the transmission gear on the 2nd); Cone gear on the turning cylinder (3) then is the normally engaged driving gear of the cone gear (5) on the rear drive power output gear axle (4); Cone gear (5) on the rear drive power output gear axle (4) then is the passive constant mesh gear of the cone gear (3) on the turning cylinder (1); Spline (6) on the rear drive power output gear axle (4) when needed just can by connect outside relevant driving device of change speed gear box such as differential box, jack shaft waits the driving that realizes walker tractor trailing wheel (being the trailer wheel).
Claims (3)
1. driving device that can make the walker tractor back-wheel drive, comprise turning cylinder (1), rear drive power output gear axle (4), drive housing (7), bearing (8), it is characterized in that: turning cylinder (1) and rear drive power output gear axle (4) be orthogonal to be assemblied in the drive housing (7) of back-wheel drive, and cone gear (5) constant-mesh on the cone gear (3) on the turning cylinder (1) and the rear drive power output gear axle (4).
2. according to claims 1 said a kind of driving device that makes the walker tractor back-wheel drive, it is characterized in that: (1) one of turning cylinder is equipped with circular gear (2), the other end is equipped with cone gear (3), circular gear (2) is the passive constant mesh gear of associated transfer gear in the walker tractor change speed gear box that needs increase back-wheel drive function, and the cone gear (3) on the turning cylinder (1) is the normally engaged driving gear of the cone gear (5) on the power output gear axle (4).
3. according to claims 1 said a kind of driving device that makes the walker tractor back-wheel drive, it is characterized in that: (4) one on power output gear axle is cone gear (5), the other end is spline (6), its cone gear (5) is the passive constant mesh gear of the upper conical gear of turning cylinder (1) (3), and its spline (6) connection exterior drive disk assembly of change speed gear box such as differential box, jack shaft drive the trailing wheel of walker tractor.
