Abstract
The utility model relates to the field of vehicle transmission shafts, in particular to a steering intermediate transmission shaft assembly. A steering intermediate transmission shaft assembly with a location sealing housing comprises a steering intermediate transmission shaft, a rubber sealing housing, a cross shaft universal joint upper segment, a cross shaft universal joint lower segment and a cross shaft assembly, wherein the cross shaft universal joint upper segment is fixedly arranged on the bottom of the steering intermediate transmission shaft, the cross shaft universal joint upper segment is connected with the cross shaft universal joint lower segment through the cross shaft assembly, the rubber sealing housing is sleeved on the steering intermediate transmission shaft assembly, a movable pair is formed between the rubber sealing housing and the steering intermediate transmission shaft, and sealing lubricating oil is filled in a sealing space between the rubber sealing housing and the steering intermediate transmission shaft. Lithium-based lubricating oil is filled in the sealing space between the rubber sealing housing and the steering intermediate transmission shaft, thus the steering intermediate transmission shaft assembly realizes sealing and noise-reducing functions, has a simple structure, is convenient for installation, and is reduced in production cost greatly under the condition of ensuring quality.
Description
Technical field
The utility model relates to the propeller-shaft field, relates in particular to a kind of tween drive spindle that turns to.
Background technology
Automotive steering is the mechanism that is used for keeping or changing vehicle traveling direction; When motor turning goes; Also to guarantee coordinated angle relation between each wheel flutter; Chaufeur makes automobile remain on straight line or turning motion state through handling steering swivel system, and above-mentioned two kinds of state of kinematic motions are changed each other.Steering system by steering handwheel, steering column, turn to essential parts such as tween drive shaft, deflector, steering drag link, steering trapezium, steering swivel to form.The motor turning tween drive shaft is carry-over moment effectively, considers the input and output shaft nonlinear arrangement, considers the centering function of tween drive shaft and deflector and steering column simultaneously.Tween drive shaft should provide Hooke's joint so that install.Turn to the bellows on the tween drive shaft not only to want carry-over moment, also should be able to play preventing ground-surface sewage and dust into the car, isolated a part of driving engine and the outer noise of car improve chaufeur and passenger's comfort.
The at present commonplace tween drive shaft dust boot that turns to is connected with tween drive shaft through bearing, and dust boot and body bottom panel are used bolt, the complex structure of dust boot, and installation procedure is various, and cost is high.
Summary of the invention
The utility model technical matters to be solved provides and a kind ofly turns to the intermediate drive axle assembly with the location seal closure; Turning to of this driving-shaft assembly is set with the rubber seal cover on the tween drive spindle; And realize the function of sealing and noise reduction through lithium base grease; Under the situation of ensuring the quality of products, greatly reduce productive costs.
The utility model is achieved in that and a kind ofly turns to the intermediate drive axle assembly with the location seal closure; Comprise and turn to joint fork on tween drive spindle, rubber seal cover, the Hooke's joint, Hooke's joint joint fork and cross assemble down; The joint fork is fixedly mounted on the bottom that turns to tween drive spindle on the said Hooke's joint; The joint fork links to each other through cross assemble between the joint fork down with Hooke's joint on the said Hooke's joint; The said rubber seal enclosure is contained in and turns on the tween drive spindle; Rubber seal cover and turn to and constitute moving sets between the tween drive spindle, said rubber seal cover and turn in the seal cavity between the tween drive spindle and be filled with sealing lubricating oil.
The described top of tween drive spindle that turns to is provided with the square groove spline.
Described rubber seal cover is oval, and the major and minor axis end of oval rubber seal cover is respectively equipped with a positioning groove.
The sealing lubricating oil of filling in the described seal cavity is a lithium base grease.
The turning to of intermediate drive axle assembly that turn to of the utility model band location seal closure is set with the rubber seal cover on the tween drive spindle; And at the rubber seal cover and turn in the seal cavity between the tween drive spindle and to fill the function that lithium base grease is realized sealing and noise reduction; Simple in structure; Easy for installation, under the situation of ensuring the quality of products, greatly reduce productive costs.
Description of drawings
Fig. 1 is the structural representation that turns to the intermediate drive axle assembly of the utility model band location seal closure;
Fig. 2 is the structure cross-sectional schematic that turns to the intermediate drive axle assembly of the utility model band location seal closure.
Among the figure: 1 turns to joint fork on tween drive spindle, 2 rubber seal covers, 3 Hooke's joints, 4 Hooke's joints joint fork, 5 cross assembles, 6 seal cavitys, 7 square groove splines, 8 positioning grooves down.
The specific embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment only to be used to the utility model is described and be not used in the restriction the utility model scope.Should be understood that in addition those skilled in the art can do various changes or modification to the utility model after the content of having read the utility model statement, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
Embodiment 1
Like Fig. 1, shown in 2; A kind ofly turn to the intermediate drive axle assembly with the location seal closure; Comprise and turn to joint fork 3 on tween drive spindle 1, rubber seal cover 2, the Hooke's joint, Hooke's joint joint fork 4 and cross assemble 5 down; Joint fork 3 is fixedly mounted on the bottom that turns to tween drive spindle 1 on the said Hooke's joint; Joint fork 3 links to each other through cross assemble 5 between the joint fork 4 down with Hooke's joint on the said Hooke's joint, and said rubber seal cover 2 is sleeved on and turns on the tween drive spindle 1, rubber seal cover 2 and turn to and constitute moving sets between the tween drive spindle 1; Said rubber seal cover 2 and turn in the seal cavity 6 between the tween drive spindle 1 and be filled with sealing lubricating oil; The sealing lubricating oil of filling in the described in the present embodiment seal cavity 6 is a lithium base grease, and lithium base grease plays the effect of sealing and noise reduction, guarantees that simultaneously countershaft assembly does not have the friction noise when rotating.
In the present embodiment, the described top that turns to tween drive spindle 1 is provided with square groove spline 7 and is convenient to assembling.
In addition in order when assembling, to prevent to adorn anti-rubber seal cover 2; Described rubber seal cover 2 is oval, and the major and minor axis end of oval rubber seal cover 2 is respectively equipped with a positioning groove 8, two protruding cooperations of positioning groove 8 and body platform; Reach circumferential positioning action; The front of rubber seal cover 2 is printed on the arrow of a directive property, and arrow matches with mark on the body platform, prevents setup error.
