Description
Technical field
The utility model relates to a kind of mid-get car member, relates in particular to minicar front drive shaft bracket.
Background technology
At present, what mid-get car generally adopted is the back-wheel drive mode, and promptly the power of driving engine is delivered to change speed gear box earlier, and the output shaft by change speed gear box passes to back axle by rear propeller shaft again, rotates to drive trailing wheel, and car load travels forward or backward.The mid-get car that has only two back-wheel drives by the lower road surface of adhesive ability coefficient the time, can not provide enough big surface driving power; During particularly by muddy or frost boiling highway section, drive wheel is absorbed in mire easily or skids and can't drive, thereby has influenced the crossing ability of automobile, brings great inconvenience for people's trip.
For the propulsive effort that strengthens mid-get car and improve its crossing ability, the afterbody that the auto vendor that has is conceiving at engine mission increases auxiliary gear box, by the transfer power of driving engine of auxiliary gear box, pass to propons by front propeller shaft again, make mid-get car select to 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.But,, then can be subjected to the influence of parts such as driving engine, change speed gear box and can't install if front propeller shaft adopts the bearing structure identical with rear propeller shaft; If adapt to the installation of bearing formula front propeller shaft, have again that structural modification is big, a complicated operation, the high deficiency of cost by the structure of improving parts such as motivation, change speed gear box.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of minicar front drive shaft bracket, in order to support the front propeller shaft that two butt joints link to each other, under the prerequisite that does not change driving engine, gearbox designs, make front propeller shaft to give propons with the transmission of power of driving engine.
The technical solution of the utility model is as follows: a kind of minicar front drive shaft bracket, this support is made of bearing, rubber bodies, locating bush and bearing, its centre bearer is positioned at locating bush, between the outer ring of bearing and locating bush rubber bodies is set, and the three is by being tightly fixed together; At the bottom of described locating bush fixed bearing, have the mounting hole that passes for bolt on this bearing.
Adopt above technical scheme, the mounting hole on the bearing is connected with cooresponding hole on the suspension of a driving engine left side by bolt, and the front propeller shaft support is fixed on the suspension of a driving engine left side.Two continuous front propeller shafts of butt joint pass from bearing, and are supported by bearing.Front propeller shaft and bearing cone free-running fit, both can rotate with respect to outside race together, again can be for convenience detach.Front propeller shaft adopts two butt joints and has the structure of certain angle of cut, by custom-designed stent support, can effectively avoid with the chassis on driving engine, change speed gear box interfere, need not change the structure of minicar engine and change speed gear box like this can install, make mid-get car on the basis of a small amount of increase cost, can select to 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, thereby strengthened the propulsive effort of mid-get car, improved the crossing ability of mid-get car greatly.
Above-mentioned rubber bodies is an annular arrangement, has arc notch at the opposite side of rubber bodies outer circumference surface.Flush fit between outside race, rubber bodies and the locating bush three is connected firmly and reliable, can effectively prevent to come off; Arc notch makes rubber bodies elastic stiffness coefficient reduce, and can play good cushioning effect.
The arc section of the middle part of above-mentioned bearing for caving in downwards, the bottom of this arc section and circular locating bush coincide, both are fixing by welding, the two ends of bearing bend continuously, form " U " shape journal stirrup, each journal stirrup is obliquely installed, and the opening of journal stirrup has mounting hole towards the arc section at bearing middle part on the plate face below described journal stirrup is positioned at.Cooresponding installation site adapts on the suspension of the set-up mode of a journal stirrup and driving engine left side, with easy disassembly and make more compact structure; 2 of front propeller shaft support employings and driving engine left side suspension are fixed, and be not only firm, and good stability.
Beneficial effect: the utlity model has simple and practical, characteristics such as connection is reliable, easy accessibility, good economy performance, it can conveniently install the front propeller shaft that two butt joints link to each other, under the prerequisite that does not change driving engine, gearbox designs, make front propeller shaft to give propons with the transmission of power of driving engine, thereby strengthened the propulsive effort of mid-get car, improved the crossing ability of mid-get car greatly.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the running condition reference diagram of Fig. 1.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
As shown in Figure 1, the utility model is made of bearing 1, rubber bodies 2, locating bush 3 and bearing 4, and its centre bearer 1 preferred roller ball-bearing casing is positioned at locating bush 3, between locating bush 3 and bearing 1 outer ring rubber bodies 2 is set, and the three is by being tightly fixed together.Rubber bodies 2 is an annular arrangement, has arc notch 2a at the opposite side of rubber bodies 2 outer circumference surfaces, and arc notch 2a makes rubber bodies 2 elastic stiffness coefficients reduce, and can play cushioning effect.The arc section of the middle part of described bearing 4 for caving in downwards, the bottom of this arc section and circular locating bush 3 coincide, both are fixing by welding, the two ends of bearing 4 bend continuously, form " U " shape journal stirrup 4a, each journal stirrup 4a is obliquely installed, and the opening of journal stirrup 4a has the mounting hole that passes for bolt towards the arc section at bearing 4 middle parts on the plate face below described journal stirrup 4a is positioned at.
