Abstract
The utility model relates to the technical field of a rear suspension of agricultural automobiles. The utility model is characterized in that a diesel engine 2 and an integrated rear axle 7 both are fixed on an automobile frame 1; the automobile frame 1 is suspended on a longitudinally placed steel plate spring 4; two rear wheels are rigidly connected through rigid members 6. The utility model has the advantages that the unsprung mass of an agricultural automobile is reduced; the relative motion between the diesel engine and the integrated rear axle is eliminated; thus, the coupled effect caused by the vibration of the unsprung mass to the sprung mass is eliminated, and the service life of a belt or a chain 3 is prolonged; the ride comfort, the amenity, and the operating stability of agricultural automobiles are enhanced; large quantities of interchangeable parts of existing agricultural automobiles can be used, and therefore, the cost of agricultural automobiles can be conveniently reduced.
Description
The utility model relates to a kind of farm vehicle, particularly relates to a kind of rear suspension field of farm vehicle.
At present, the rear suspension of domestic agricultural tricycle and agricultural four-wheeled all adopts the vertical non-independent rear suspension of steel spring of putting, and in order to be fit to peasant's the level of consumption and cost-cutting, all agricultural tricycle has all adopted connected rear axle with the agricultural four-wheeled that accounts for 4%.So-called connected rear axle is meant device sets such as clutch, speed change and main deceleration in a casing, and main the deceleration be not the spiral bevel gear transmission, but spur gear drive.Thereby it is cheap.The existing farm vehicle that uses connected rear axle, all be connected rear axle is horizontally placed on about in the middle of two rear wheels, two ends, the left and right sides with about the back bridge tube be connected, two jack shafts in the connected rear axle drive two trailing wheels by the back bridge tube.And diesel engine is fixed on the vehicle frame, and vehicle frame is suspended at vertical putting on the steel spring, and vertically puts steel spring and be fixed on the bridge tube power input shaft in use for diesel engine belt or the chain drive connected rear axle.Because diesel engine is a sprung weight, and connected rear axle belongs to unsprung weight, therefore the road surface influences each other to the vibration of the severe jolt of connected rear axle and diesel engine and intercouples, and the two has relative motion, very easily make the belt or the chain of transferring power damage fracture, and destroyed ride comfort, traveling comfort and the road-holding property of farm vehicle greatly.
Most of agricultural four-wheeled does not adopt connected rear axle in order to improve traveling comfort, but adopted the main deceleration spiral bevel gear transmission back axle of orthodox car, scalable transmission shaft driving rear axle with the band universal-joint, other technologies also all are the orthodox car technology of continuing to use, and have just changed spark ignition engine into diesel engine.As everyone knows, this conventional art structure is the cost height for various reasons, and peasant consumption is not risen.Though Beijing one tame agricultural depot has adopted connected rear axle recently by retrieval, but use before driving, the double-pendulum arms independent suspension, as everyone knows, because of propons is a steeraxle, serve as drive axle again, thereby the guiding mechanism complexity, universal-joint also must use constant-velocity universal joint, thereby causes price still high.Not only comfortable but also inexpensive, draw to such an extent that to run a good foot be the mysterious key at gate of opening up markets more.Otherwise the peasant will cannot afford.As totally 320 ten thousand of agricultural tricycle in 1999 and agricultural four-wheeled output, farm vehicle only accounts for 460,000, only is 14%, and visible price height is the major cause of agricultural four-wheeled slack market.
The purpose of this utility model is exactly in order to overcome the shortcoming of existing technologies, has both used connected rear axle reducing the price of farm vehicle, and can improve ride comfort, traveling comfort and the road-holding property of vehicle, and agricultural four-wheeled price is controlled in ten thousand yuan.
The utility model is achieved through the following technical solutions: a kind of connected rear axle formula is vertical puts the semi-independent rear suspension novel agricultural of steel spring car and is made up of diesel engine, connected rear axle, the vertical institute such as steel spring of putting, it is characterized in that diesel engine 2 and connected rear axle 7 all are fixed on the vehicle frame 1, vehicle frame 1 is suspended on vertical putting on the steel spring 4 again, left and right sides rear wheel is rigidly connected with rigid member 6, and the vertical steel spring 4 of putting is fixed on the rigid member 6 that links two trailing wheels.The left and right sides axle drive shaft of two rear wheels was to be connected by universal joint cross-head 11 and tween drive shaft 10 by inner shaft 12 about connected rear axle drove, and tween drive shaft 10 is connected by universal joint cross-head 9 and outer semiaxis 8 again.Inner shaft 12 is with the male splines binding that matches with differential bevel wheel internal splined hole in the connected rear axle 7, and the flexible in the differential bevel wheel internal splined hole of the male splines of inner shaft 12 1 ends is moved or the tween drive shaft 10 of axle drive shaft is made up of two axles that spline fitted pays that have of telescopic moving mutually.
The utility model has the advantages that and alleviated unsprung weight greatly, thereby vibrational load is reduced, eliminate the relative motion of diesel engine and connected rear axle in the prior art thereby prolonged life-span of drive belt or chain greatly, greatly improve ride comfort, traveling comfort and the road-holding property of vehicle, used a large amount of general parts of existing farm vehicle simultaneously again.Therefore also greatly reduce the price of farm vehicle.
The utility model is further described by embodiment below in conjunction with accompanying drawing;
Accompanying drawing 1 is a front view of the present utility model; Fig. 2 is a birds-eye view; Fig. 3 is that A among Fig. 1 is to view.In the accompanying drawing, the 1st, vehicle frame, the 2nd, diesel engine, the 3rd, belt or chain, in order to the power of diesel engine 2 is passed to connected rear axle 7, the 4th, the vertical steel spring of putting, in order to vehicle frame and the loading of suspending, it is fixed in order on the rigid member axle 6 that links two rear wheels, the 5th, support is in order to connected rear axle 7 is fixed on the linkage frame on the vehicle frame 1, the 6th, rigid member axle, in order to link two rear wheels, the 8th, the outer semiaxis in the axle drive shaft is connected by universal joint cross-head 9 and tween drive shaft 10, and the 10th, tween drive shaft, be connected by universal joint cross-head 11 and inner shaft 12, tween drive shaft 10 is integral shafts or is made up of two axles that inside and outside spline fitted pays that have of mutual telescopic moving that 12 is inner shaft, and the outer end is connected by universal joint cross-head 11 and tween drive shaft, the inner is paid the differential bevel wheel internal splined hole by spline and is connected, and the finishing bevel gear cuter of diff drives inner shaft 12 rotations and inner shaft 12 telescopic movings or flexible are moved.
After the power of diesel engine 2 is delivered to the power input shaft of connected rear axle 7 by belt or chain 3, through clutch, speed change, diff in the main gear down device drives inner shaft, tween drive shaft and the rotation of outer semiaxis, thereby drive wheels motion, when road is uneven, because inner shaft 12 flexible or tween drive shaft 10 flexibles in the differential bevel wheel hole, vibration of vehicle top spinach can not pass on the connected rear axle 7 like this, and because the damping of vibrations of steel spring, so ride comfort of vehicle, traveling comfort and road-holding property improve greatly, because diesel engine and connected rear axle all are fixed on the vehicle frame, the two does not have relative motion, so belt or chain 3 are not fragile.
