Abstract
The utility model discloses a master pin cover for a truck front steering axle. The inner side face of the master pin cover is an inclined plane structure. A seal ring groove is arranged on the inner side face. An end face O-shaped seal ring is arranged in the seal ring groove. The master pin cover is provided with a grease nipple threaded hole. According to the master pin cover for the truck front steering axle, the inclined plane structure and a threaded hole structure are adopted, when the master pin cover, a knuckle and the O-shaped seal ring are assembled, a clamp spring is used for compressing location, a master pin cover inclined plane compresses the O-shaped seal ring under the action of the clamp spring location, and meanwhile the O-shaped seal ring and the knuckle are tightly attached under the compressing action of the master pin cover, good tightness is guaranteed, and situations, such as water ingress and grease overflow, can be preferably prevented from occurring, and meanwhile due to the fact that the master pin cover is provided with the grease nipple threaded hole in a machining mode, the master pin cover for the truck front steering axle is convenient to machine and install, the structure and assembly procedure are simplified, and tightness is improved.
Description
Technical field
The utility model relates to a kind of kingpin cap, is specifically related to a kind of front steering axle of truck kingpin cap.
Background technology
Front steering axle of truck just simply is installed on the steering swivel with kingpin cap at present, then fixes by jump ring, and the shortcoming of the steering yoke bolt lid arrangement of prior art is that kingpin cap is just spacing by jump ring, and kingpin cap can produce longitudinal travel to a certain degree.This displacement meeting with respect to steering swivel causes the variation of air/oil fat volume between kingpin cap, stub and the steering swivel.So just can't guarantee leak tightness, lubricating oil will overflow during charging-up lubricant oil, can enter in the steering yoke bolt hole when having ponding or other pollutantss on the kingpin cap simultaneously.Thereby can't play simultaneously waterproof and seal grease effect at height and circumferencial direction, cause the generation of the faults such as kingpin bore water inlet, corrosion.In addition, the grease nipple hole processes at steering swivel usually, complex procedures, and cost is high.
Summary of the invention
The purpose of this utility model is for overcoming above-mentioned the deficiencies in the prior art, provides under a kind of prerequisite not affecting other parts assembling, realizes the preferably installation of sealing effectiveness and grease nipple.
For achieving the above object, the utility model adopts following technical proposals:
A kind of front steering axle of truck kingpin cap, the kingpin cap medial surface is a ramp structure, and the grease nipple tapped bore is set on the kingpin cap.
The utility model has designed inclined-plane and thread pore structure under the prerequisite that does not affect other parts installations.The utility model adopts inclined-plane and thread pore structure, when kingpin cap, steering swivel and O RunddichtringO assemble, compress the location by jump ring, the kingpin cap inclined-plane compresses the O RunddichtringO under the jump ring positioning action, simultaneously under the thrust effect of kingpin cap, also fit tightly between O RunddichtringO and the steering swivel, guarantee preferably leak tightness; Process the grease nipple tapped bore on the kingpin cap simultaneously, be convenient to processing and installation.
The beneficial effects of the utility model are, adopt ramp structure by kingpin cap and O RunddichtringO binding site, guarantee between kingpin cap, steering swivel and the O RunddichtringO better sealing function, can prevent from preferably occuring into situations such as water and grease overflow; Processing grease nipple tapped bore is convenient to processing and installation on the kingpin cap, simplifies the structure like this and assembly process, has improved leak tightness.

The specific embodiment
Below in conjunction with drawings and Examples the utility model is further set forth, should be noted that following explanation only is in order to explain the utility model, its content not to be limited.
Shown in Fig. 1-5, a kind of front steering axle of truck kingpin cap, kingpin cap 2 medial surfaces are a ramp structure, and the grease nipple tapped bore is set on the kingpin cap 2, are convenient to install grease nipple 3.
The installation method of kingpin cap 2 described in the utility model is, grease nipple 3 is tightened on the kingpin cap 2, and O RunddichtringO 5 is placed on the steering swivel 1, installs kingpin cap 2 and grease nipple 3 assemblies, gently presses kingpin cap 2, and jump ring 4 is installed on the steering swivel 1.
The utility model has designed inclined-plane and thread pore structure under the prerequisite that does not affect other parts installations.The utility model adopts inclined-plane and thread pore structure, when kingpin cap 2, steering swivel 1 and O RunddichtringO 5 assemble, compress the location by jump ring 4, kingpin cap 2 inclined-planes compress O RunddichtringO 5 under jump ring 4 positioning actions, simultaneously under the thrust effect of kingpin cap 2, also fit tightly between O RunddichtringO 5 and the steering swivel 1, guarantee preferably leak tightness; Process the grease nipple tapped bore on the kingpin cap 2 simultaneously, be convenient to processing and grease nipple 3 is installed.
The utility model adopts ramp structure by kingpin cap 2 and O RunddichtringO 5 binding sites, guarantees between kingpin cap 2, steering swivel 1 and the O RunddichtringO 5 better sealing function, can prevent from preferably occuring into situations such as water and grease overflow; Processing grease nipple tapped bore on the kingpin cap 2 is convenient to processing and grease nipple 3 is installed, and simplifies the structure like this and assembly process, has improved leak tightness.
Although above-mentionedly by reference to the accompanying drawings the specific embodiment of the present utility model is described; but be not the restriction to the utility model protection domain; on the basis of the technical solution of the utility model, those skilled in the art do not need to pay various modifications that creative work can make or distortion still in protection domain of the present utility model.
