Description

Knuckle pin shaft oil injection structure

Technical field

The utility model relates to automotive fields, and in particular to a kind of knuckle pin shaft oil injection structure.

Background technique

Knuckle is mounted on the end of axle generally by pin shaft, i other words, it can by knuckle and axle using pin shaft The connection of rotation, in order to guarantee wheel flexible rotating, needs the fit clearance in pin shaft and knuckle to realize the steering of wheel Interior filling lubricating oil；It include upper and lower two parts due to being used to install the axis hole of pin shaft on knuckle, existing oil injection structure is point Pump nozzle is not installed in the top end face of pin shaft and bottom face, since the gravity of lubricating oil leads to the note of the pump nozzle of pin shaft bottom face The oily frequency is very high, and pump nozzle is mounted on pin shaft lower end surface, so that pump nozzle and ground are closer, oil injection operation is inadequate It is convenient, it is not easy to the daily maintenance of vehicle.

Utility model content

In view of the deficiencies of the prior art, the purpose of this utility model is intended to provide a kind of knuckle pin shaft oil injection structure, Its oiling frequency that can reduce knuckle pin shaft, passes through the daily maintenance for being easy to vehicle.

To achieve the above object, the utility model adopts the following technical solution：

Knuckle pin shaft oil injection structure including knuckle, is worn the pin shaft connect in the axis hole of knuckle, is fixed with knuckle Spindle arm and pump nozzle, spindle arm include at least that a upper surface and one is bonded with the medial surface of knuckle outside Side, pump nozzle are mounted on the upper surface of spindle arm, are provided with first passage on spindle arm, and one end of the first passage is prolonged Extend to upper surface, the other end extends to lateral surface, be provided with second channel on knuckle, one end of the second channel extend to turn The inner wall of knuckle axis hole is extended to medial surface, the other end of section；In outer side and medial surface joint place, first passage and The connection of two channels.

First passage extends to lateral surface and forms an opening, and the protrusion that the opening periphery forms an annular is located on lateral surface Portion.

Spindle arm is bolted to connection with knuckle.

First passage includes by upper surface towards the first hole of spindle arm internal stretch, and by lateral surface towards horizontal drawing Second hole of lever arm internal stretch, the second hole are connected to the first hole.

The beneficial effects of the utility model are：

Compared with the prior art, the utility model opens up oil circuit on spindle arm and knuckle, pass through lubricating oil can Pump nozzle, spindle arm, knuckle enter above-mentioned knuckle and the fit clearance of pin shaft is lubricated pin shaft, meet pin shaft Lubricating requirement；And due to being the upper surface that pump nozzle is mounted on to spindle arm, making the oil inlet of pump nozzle is upward or tiltedly Upward, lubricating oil will not leak downwards, the frequency of oiling be reduced, convenient for the daily maintenance of vehicle.

Specific embodiment

In the following, being further described in conjunction with the drawings and specific embodiments to the utility model：

It as shown in Figure 1,2,3, 4, is the knuckle pin shaft oil injection structure of the utility model comprising knuckle 10, pin shaft 20, spindle arm 30 and pump nozzle 40, wherein pin shaft 20, which is worn, to be connect in the axis hole of knuckle 10, spindle arm 30 and steering Section 10 is fixedly connected, and same as the prior art, spindle arm is for knuckle to be connect with track rod；This is practical new In type, spindle arm 30 includes a upper surface 31 and a lateral surface 32, the medial surface 11 of the lateral surface 32 and knuckle 10 Fitting, and spindle arm 30 and knuckle 10 are crossed using bolt, the two is fixed；Pump nozzle 40 is fixedly mounted on table On face 31, in this way, the oil inlet of pump nozzle 40 can be made to be to be arranged upward, or be arranged obliquely.It is provided in spindle arm 30 First passage 33 is provided with second channel 12 on knuckle 10, which is connected to second channel 12 forms an oiling Channel, the oiling one end of the channel are connected to the fit clearance of pump nozzle 40, the other end connection knuckle 10 and pin shaft 20.Specifically, One end of first passage 33 extends to the formation of upper surface 31 one opening 311, the other end and extends on lateral surface 32, pump nozzle 40 It can be mounted on by way of being spirally connected in opening 311, one end of second channel 12 extends to the medial surface 11 and shape of knuckle 10 The fit clearance to section 10 and pin shaft 20 is then extended at opening 111, the other end, is fixed in spindle arm 30 and knuckle 10 Afterwards, 111 conducting of the other end of first passage 23 and opening.

Compared with the prior art, the utility model opens up oil circuit on spindle arm and knuckle, pass through lubricating oil can The fit clearance that pump nozzle, spindle arm, knuckle enter above-mentioned knuckle 10 and pin shaft 20 is lubricated pin shaft, meets The lubricating requirement of pin shaft 20；And due to being the upper surface that pump nozzle 40 is mounted on to spindle arm 30, make the oil inlet of pump nozzle 40 It mouthful is that upward or obliquely, lubricating oil will not leak downwards, the frequency of oiling be reduced, convenient for the daily maintenance of vehicle.

It should be noted that above-mentioned spindle arm 30 is bolted with knuckle 10, certainly, spindle arm 30 and turn It can also be fixed using other connection types to section 10, be connected to as long as can satisfy first passage 33 with second channel 12.

In above scheme, first passage 33 extends to lateral surface 32 and forms an opening, is located at the opening periphery on lateral surface The lug boss of an annular is formed, after benefit is tightened by bolts spindle arm 30 and knuckle 10, lug boss is centered around first passage 33 and second channel 12 docking at periphery, guarantee at this have good leakproofness.

For the ease of processing, above-mentioned first passage 33 includes first towards 30 internal stretch of spindle arm by upper surface Hole, and by lateral surface towards the second hole of 30 internal stretch of spindle arm, the second hole is connected to the first hole.

Above embodiments are only to illustrate the technical solution of the utility model, rather than its limitations；Although referring to aforementioned reality Example is applied the utility model is described in detail, those skilled in the art should understand that, it still can be to preceding Technical solution documented by each embodiment is stated to modify or equivalent replacement of some of the technical features, and these It modifies or replaces, the spirit and model of various embodiments of the utility model technical solution that it does not separate the essence of the corresponding technical solution It encloses.
