Abstract
The utility model discloses a connecting structure of a speed changer on a vehicle rear fork. The connecting structure of the speed changer on the vehicle rear fork comprises the speed changer, the rear fork and a wheel axle which penetrates through a shell body of the speed changer and is connected with the rear fork. The connecting structure of the speed changer on the vehicle rear fork is characterized in that a positioning support lug is arranged on the rear fork, a connecting support lug which corresponds to the positioning support lug is arranged on the shell body of the speed changer, and the positioning support lug is fixedly connected with the connecting support lug. Connecting holes which correspond mutually are formed in the positioning support lug and the connecting support lug so as to fix the positioning support lug and the connecting support lug, and the positioning support lug and the connecting support lug are fixedly connected through a bolt which penetrates through the connecting holes. According to the connecting structure of the speed changer on the vehicle rear fork, a three-point fixing structure is adopted to fix the speed changer, so that the speed changer is solidly connected; and meanwhile, excessive local stress and damage, caused by a torque-bearing structure of a traditional electric vehicle wheel axle, of the wheel axle and the rear fork are avoided.
Description
Technical field
The utility model relates to a kind of connection structure of battery-driven car chain stay, the particularly change-speed box connection structure on the vehicle chain stay.
Background technology
At present, be equipped with change-speed box on two-wheeled on the market or three-wheel vehicle, described change-speed box is generally run through case of transmission and be connected with chain stay by wheel shaft.This connection structure is had relatively high expectations to wheel shaft, and when starting vehicle, when change-speed box and motor rotation, change-speed box and motor internal part will high-speed operations, and then make the wheel shaft that connects change-speed box be subject to a rotary torque.Simultaneously, under the weight of change-speed box and motor, wheel shaft also must be born axially and load radially.From foregoing description as can be known, wheel shaft need to be born axial and radially load and the rotary torque of change-speed box, and this requirement of strength to wheel shaft is very high.In order to strengthen load force, often need to make larger-diameter wheel shaft, neither the resource of wasting again attractive in appearance.In addition, wheel shaft is after long-time running, because change-speed box and motor can produce shake in the running, thereby make wheel shaft and chain stay joint generation friction, after long-time, will cause wheel shaft and chain stay and wheel shaft joint generation to damage greatly, and then impact is used.
Simultaneously, change-speed box only fixes by wheel shaft.When mounted, need first wheel shaft to be run through the two ends that are fixed on again chain stay after change-speed box, need bear the weight of change-speed box when wheel shaft is installed, install cumbersome.Simultaneously, in the process that change-speed box and wheel shaft is fixing, need repeatedly adjust the position of change-speed box, with the position of guaranteeing that change-speed box and wheel shaft assemble.
The utility model content
The purpose of this utility model is to provide a kind of service life and the large connection structure of change-speed box on the vehicle chain stay of intensity of load that has improved wheel shaft in order to solve above-mentioned the deficiencies in the prior art.
To achieve these goals, the connection structure of change-speed box on the vehicle chain stay that the utility model is designed, it comprises change-speed box, chain stay and the wheel shaft that runs through case of transmission, the wheel shaft two ends are connected with chain stay, it is characterized in that being provided with a positioning lug on chain stay, be provided with a connection journal stirrup corresponding with positioning lug on the housing of change-speed box, described positioning lug be connected journal stirrup and be connected.
For the stationary positioned journal stirrup be connected journal stirrup, positioning lug be connected journal stirrup on be equipped with corresponding connecting bore, positioning lug be connected journal stirrup by bolt-through connecting bore captive joint.
Further, also be provided with the motor that is attached thereto above change-speed box.
The connection structure of the change-speed box that the utility model obtains on the vehicle chain stay adopts 3 fixed sturctures to fix change-speed box, makes change-speed box connect more firm; Saved cost of manufacture, used than wheel shaft less in prior art just more to reach operating needs; Simultaneously, by increasing positioning lug and being connected journal stirrup, reduce the constant intensity requirement to the installation site, improved reliability, also avoided the conventional electric axletree to bear the structure of moment of torsion and the wheel shaft that causes and the chain stay local stress is excessive and damage.The distance that connects between journal stirrup and wheel shaft is larger, has increased the arm of force, has improved the whole force structure of housing, improves its reliability.
Description of drawings
Fig. 1 is the connection structure schematic diagram of change-speed box on the vehicle chain stay in embodiment;
Fig. 2 is the lateral plan of Fig. 1.
In figure: change-speed box 1, chain stay 2, wheel shaft 3, positioning lug 4, connection journal stirrup 5, connecting bore 6, motor 7.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Embodiment:
the connection structure of the change-speed box that the present embodiment provides on the vehicle chain stay, as Fig. 1, shown in Figure 2, it comprises change-speed box 1, chain stay 2 and run through the housing of change-speed box 1 and the wheel shaft 3 that is connected with chain stay 2, two fork ends at chain stay 2 are equipped with for the mounting groove that wheel shaft 3 is installed, the two ends of described wheel shaft 3 are placed in the mounting groove that is arranged on chain stay 2, also be provided with the motor 7 that is attached thereto above change-speed box 1, be provided with a positioning lug 4 on chain stay 2, be provided with a connection journal stirrup 5 corresponding with positioning lug 4 on the housing of change-speed box 1, positioning lug 4 be connected journal stirrup 5 on be equipped with corresponding connecting bore 6, positioning lug 4 be connected journal stirrup 5 and be connected by bolt-through connecting bore 6.
In the present embodiment, 3, wheel shaft bears axially and load radially, positioning lug 4 be connected journal stirrup 5 and bear rotary torque.Wheel shaft 3 has formed 3 connections with point of connection and the positioning lug 4 of chain stay 2 with the point of connection that is connected journal stirrup 5, and more firm, rocking of generation is little.
Need to prove at last, above embodiment is only in order to the technical solution of the utility model to be described but not the restriction technologies scheme, although the applicant has been described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, those are modified to the technical solution of the utility model or are equal to replacement, and do not break away from aim and the scope of the technical program, all should be encompassed in the middle of claim scope of the present utility model.
