Abstract
The utility model belongs to the technical field of automobile part processing, specifically relates to an automobile transmission, and in particular relates to a shift fork of a large truck transmission. According to the technical scheme, a groove is formed in the front side surface or the rear side surface of the shift fork of the large truck transmission. In a preferential implementation mode, grooves can also be formed in the front side surface and the rear side surface of the shift fork of the large truck transmission at the same time. The shift fork has the beneficial effects that the grooves are formed in the side surfaces of the shift fork of the large truck transmission, the weight of the shift fork is reduced, and thus the gear shifting operation needs small force and can be smoother; and the grooves and a shift fork body can form a groove-shaped structure, so that the weight of the shift fork is reduced, and moreover, the strength of the shift fork is ensured.
Description
Technical field
The utility model belongs to the auto parts and components processing technique field, is specifically related to a kind of automotive transmission, relates in particular to a kind of large truck gearshift fork.
Technical background
As shown in Figure 1, existing large truck gearshift fork 1, its structure is abundant, and weight is heavier, causes when carrying out shifting of transmission, and the steering force that needs is larger.
The model utility content
In order to overcome above-mentioned deficiency, the utility model provides a kind of large truck gearshift fork.
The technical solution of the utility model is:
A kind of large truck gearshift fork has groove on the leading flank of described large truck gearshift fork or trailing flank.
As preferred implementation of the present utility model, can also be simultaneously have groove on the leading flank of large truck gearshift fork and trailing flank.
The material of described large truck gearshift fork is cast steel or cast aluminium.
The beneficial effects of the utility model are: by have groove on the side of large truck gearshift fork, alleviated the weight of shift fork, the power that gear-change operation is needed is less, thereby gear-change operation is more smooth and easy; Because groove and shift fork body can form bathtub construction, make shift fork in weight reduction, also guaranteed its intensity.
Description of drawings
Fig. 1 is the structural representation of existing large truck gearshift fork.
Fig. 2 is the main TV structure schematic diagram of large truck gearshift fork of the present utility model.
Fig. 3 is the A-A sectional view of large truck gearshift fork of the present utility model.
The existing large truck gearshift fork of being labeled as in accompanying drawing: 1-, 2-large truck gearshift fork, 3-groove, 4-trailing flank, 5-leading flank.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described.
Embodiment 1
A kind of large truck gearshift fork has groove 3 on the leading flank 5 of described large truck gearshift fork 2, thereby has alleviated the weight of large truck gearshift fork 2, and the power that gear-change operation is needed is less, thereby gear-change operation is more smooth and easy; Body formation bathtub construction due to groove and large truck gearshift fork 2 makes shift fork in weight reduction, has also guaranteed its intensity.The material of described large truck gearshift fork is cast aluminium.
A kind of large truck gearshift fork has groove 3 on the trailing flank 4 of described large truck gearshift fork 2, thereby has alleviated the weight of large truck gearshift fork 2, and the power that gear-change operation is needed is less, thereby gear-change operation is more smooth and easy; Body formation bathtub construction due to groove and large truck gearshift fork 2 makes shift fork in weight reduction, has also guaranteed its intensity.The material of described large truck gearshift fork is cast aluminium.
A kind of large truck gearshift fork, as shown in Figures 2 and 3, have simultaneously groove 3 on the leading flank 5 of large truck gearshift fork 2 and trailing flank 4, thereby alleviated the weight of large truck gearshift fork 2, the power that gear-change operation is needed is less, thereby gear-change operation is more smooth and easy; Because the body of the groove of front and back sides and large truck gearshift fork 2 forms " I-shaped " structure, make shift fork in weight reduction, also guaranteed its intensity.The material of described large truck gearshift fork is cast steel.
The above embodiment has only expressed preferred implementation of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.Should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion, improve and substitute, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
Claims (3)
