The utility model provides a following technical scheme: the utility model provides an electric pedal drive mechanism's guiding axle, is equipped with the antifriction layer including the cylindrical axis body on the circumference terminal surface at the axial both ends of axis body, and the outer peripheral face on antifriction layer is in the coplanar with the outer peripheral face of axis body.

Description

Guide shaft of electric pedal transmission mechanism

Technical Field

The utility model relates to an automobile-used electric pedal accessory, in particular to electric pedal drive mechanism's guiding axle.

Background

The electric pedal is a pedal which can be automatically stretched and retracted and is used in an automobile, and provides service for the high chassis automobile with up-down convenience.

The electric pedal is driven to stretch through a transmission mechanism linked with a motor inside the automobile. The guide shaft, which is the most important component in the transmission mechanism, is a columnar shaft body, two axial ends of the shaft body are sleeved with guide blocks, and the guide blocks are linked with other accessories to reciprocate along the axial direction of the shaft body. The guide block slides on the guide shaft for a long time, and the friction between the guide block and the guide shaft can cause the abrasion of the guide shaft. After the guide shaft is abraded, the guide block moves on the guide shaft, and the guide shaft is blocked, so that the replacement cost and the replacement step are complicated.

Disclosure of Invention

The utility model provides a not enough to prior art exists, the utility model provides a wear-resisting, simple structure's electric pedal drive mechanism's guiding axle.

In order to achieve the above purpose, the utility model provides a following technical scheme: the utility model provides an electric pedal drive mechanism's guiding axle, is including cylindrical axis body, its characterized in that: the shaft body is characterized in that anti-friction layers are arranged on circumferential end faces at two axial ends of the shaft body, and the outer circumferential faces of the anti-friction layers and the outer circumferential face of the shaft body are located on the same plane.

Adopt above-mentioned technical scheme, the axial both ends of axis body are for the friction portion with the guide block friction, through set up antifriction layer at its axial both ends, the frictional force between reducible guide block and the axis body on the one hand, and on the other hand can provide the protection to the axis body, prevents the axis body wearing and tearing, and the aforesaid sets up not only processing convenience, simple structure moreover.

The utility model discloses further set up to: the circumference at the axial both ends of axis body is seted up flutedly, antifriction layer for filling in the packing antifriction layer in this recess.

Wherein, the recess of the circumference on the axial both ends of axis body is the heliciform recess.

Adopt above-mentioned technical scheme, set up the recess through the axial both ends at the axis body to pack antifriction medium to this recess in through the mode of pouring, processing is convenient, makes to have self-lubricating nature between axis body and the guide block, reduces the friction, provides the guard action to the axis body. The grooves are arranged to be spiral grooves, so that the coverage surface of the anti-friction layer on the shaft body is wider.

The present invention will be further described with reference to the accompanying drawings.

Drawings

fig. 2 is a schematic structural diagram of an embodiment of the present invention;

fig. 3 is an enlarged schematic view of a portion I of fig. 2.

Detailed Description

As shown in fig. 1-3, the guide shaft of an electric pedal transmission mechanism is a cylindrical shaft body 1, and the shaft body 1 has anti-friction layers 2 at both axial ends, and in order to maintain balance at both ends of the shaft body 1, the anti-friction layers 2 at both ends of the shaft body 1 may be symmetrically disposed, and of course, symmetry and asymmetry may be determined according to specific design. The outer peripheral surface of the anti-friction layer 2 and the outer peripheral surface of the shaft body 1 are on the same plane. Because the axial both ends of axis body 1 are the friction portion 11 with the guide block friction, through set up antifriction layer 2 at its axial both ends, the frictional force between reducible guide block and the axis body 1 on the one hand, and on the other hand can provide the protection to axis body 1, prevents the wearing and tearing of axis body 1.

The embodiment of the utility model provides an in, the periphery at the axial both ends of axis body 1 upwards seted up recess 3, recess 3 can be for the annular groove who sets up along the 1 outer peripheral face of axis body, and annular groove can be a plurality of along the 1 axial side by side settings of axis body, and antifriction layer 2 is for filling the packing antifriction layer in this recess 3. The anti-friction layer 2 is a solid layer formed after resin or rubber is poured into the groove 3 after being dissolved and solidified, specifically can be a mixture of PTFE and fibers, can form a layer of good transfer film to protect the counter shaft body 1, and provides self-lubricating performance of the bearing. The groove 3 can be annular or spiral, so that the covering surface of the groove 3 on the shaft body 1 is wider. Of course, it is also possible to form an annular notch on the outer circumferential surface of each of the two axial ends of the shaft body 1, and to sleeve the anti-friction layer 2 in the annular notch after the anti-friction layer is directly added into a sleeve-shaped body. Such a change can be realized without any inventive effort with reference to the present embodiment.
