Abstract
The utility model discloses a car constant velocity cardan joint protecting sheathing structure relates to car technical field, car constant velocity cardan joint protecting sheathing structure includes shell (5) and protective sheath (4), designs seal groove (1) of three round pin festival shells to be complete cylinder structure, remains partial arc wall (2) part to save material and weight reduction.
Description
Technical field
The utility model relates to automobile technical field, particularly relates to a kind of constant velocity universal joint protecting sheathing structure
Background technique
The constant velocity driving shaft assembly that in prior art, riding vehicle is conventional, the universal joint be connected with speed changer or retarder is generally three ball pin style constant speed universal joint.This three ball pin style constant speed universal joint forms inner seal structure, the inside repack with grease by axostylus axostyle, sheath and three pin joint shells, and the housing profile for non-maintaining structure three pin joint shell has three uniform curve baths, is incomplete cylindrical structure; Sheath and curve bath matching part also have three corresponding projections, and formation is tightly connected; The cylindrical body of housing is processed with seal groove, matches with sheath, the three ball pin style constant speed universal joint sealing of prior art is poor, and replaceable rate is lower.
Model utility content
In order to solve the problem, the utility model provides a kind of new constant velocity universal joint protecting sheathing structure.
A kind of CV joint for car protecting sheathing structure, comprise shell and protecting jacket, described shell is provided with seal groove and curve bath, described seal groove is round column structure, described protecting jacket is connected with shell, described protecting jacket is cylindrical, described protecting jacket is thin wall hollow bellows-like structure, described shell and protecting jacket are interference fit, the hollow structure of described protecting jacket can make seal groove pass, pass through interference fit, set casing and protecting jacket, the seal groove of round column structure and protecting jacket can make better tightness between described two parts, the curve bath simultaneously retained decreases the weight making material and alleviate constant velocity universal joint entirety.
Described enclosure is cavity structure, for placing constant velocity universal joint ball pin;
Described CV joint for car protecting sheathing structure comprises axostylus axostyle, is provided with through hole in the middle part of described protecting jacket, and described axostylus axostyle is connected to described enclosure constant velocity universal joint ball pin by described through hole through protecting jacket;
Described curve bath is evenly distributed on case surface, is connected with described seal groove, is connected with protruding structure between described curve bath.
The utility model CV joint for car protecting sheathing construction might be advantageous effect: described seal groove is made as round column structure and decreases making step; save time and increase work efficiency; the curve bath retained decreases the weight making material and alleviate constant velocity universal joint entirety, and the seal groove of round column structure and columniform protecting jacket coordinate the sealing more can strengthened between the two.
Accompanying drawing explanation
Fig. 1 is the utility model constant velocity universal joint protecting sheathing structural representation.
Fig. 2 is constant velocity universal joint sectional drawing.
Wherein: 1, seal groove; 2, curve bath; 3, protruding structure; 4, protecting jacket; 5 shells; 21, axostylus axostyle.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment, the utility model is described in further detail.
The utility model provides a kind of new constant velocity universal joint protecting sheathing structure as shown in Figure 1.
A kind of CV joint for car protecting sheathing structure, comprise shell 5 and protecting jacket 4, described shell 5 is provided with seal groove 1 and curve bath 2, described seal groove 1 is round column structure, described protecting jacket 4 is connected with shell 5, described protecting jacket 4 is cylindrical, described protecting jacket 4 is thin wall hollow bellows-like structure, described shell 5 is interference fit with protecting jacket 4, the thin wall hollow bellows-like structure of described protecting jacket 4 can make seal groove 1 pass, pass through interference fit, set casing 5 and protecting jacket 4, the seal groove 1 of round column structure and protecting jacket 4 can make better tightness between described two parts, the curve bath 2 simultaneously retained decreases the weight making material and alleviate constant velocity universal joint entirety.
The utility model provides a kind of new constant velocity universal joint protecting sheathing structure as shown in Figure 2, and described shell 5 inside is cavity structure, for placing constant velocity universal joint ball pin;
Described CV joint for car protecting sheathing structure is also provided with axostylus axostyle 21, is provided with through hole in the middle part of described protecting jacket 4, and described axostylus axostyle 21 is connected to the constant velocity universal joint ball pin of described shell 5 inner chamber through protecting jacket 4 by described through hole;
Described curve bath 2 is evenly distributed on shell 5 surface, is connected, is connected with protruding structure 3 between described curve bath 2 with described seal groove 1.
Described seal groove 1 is made as round column structure and decreases making step; save time and increase work efficiency; the curve bath 2 retained decreases the weight making material and alleviate constant velocity universal joint entirety, and the seal groove 1 of round column structure and columniform protecting jacket 4 coordinate the sealing more can strengthened between the two.
Above content is in conjunction with concrete preferred implementation further detailed description of the utility model, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, some simple deduction or replace can also be made, all should be considered as belonging to protection domain of the present utility model.
