Description

Piston with lightening hole on face window

Technical Field

The utility model belongs to the technical field of the piston, concretely relates to face window takes piston of lightening hole.

Background

The motorcycle engine piston is an important structure in a motorcycle engine, but the piston structure in the prior art is fixed, but the weight of the piston is fixed, the weight cannot be reduced, the processing cost can be increased, the abrasion of the piston can be accelerated in the using process, and the applicability and the practicability are limited.

Disclosure of Invention

The utility model aims at providing a face window area lightening hole's that structure sets up rationally and the suitability is strong piston.

Realize the technical scheme of the purpose of the utility model is a piston of face window area lightening hole, including integrated into one piece's piston head and skirt section the annular has been seted up to the lateral surface of piston head the face window has been seted up to the symmetrical side of skirt section seted up the locking hole on the lateral wall of skirt section, the face window extends to the middle part of piston head for U font and both ends, the locking hole is in the recess of U font two waist shape lightening holes have been seted up on the face window, waist shape lightening hole is in two vertical portions of U font and uses the locking hole to set up as the central line symmetry.

The piston head and the center of the skirt part are provided with a flared piston rod mounting hole which is communicated, and the piston head is provided with a positioning hole which is communicated with the piston rod mounting hole.

The bottom surface of the skirt part is integrally formed with two fin plates, and the two fin plates are symmetrically arranged by taking the piston head as a central line by taking the locking hole as a central line.

The inner wall of the locking hole is provided with a limiting ring groove, the end part of the locking hole is provided with a guide groove communicated with the limiting ring groove, and the fin plate is isosceles trapezoid and is 1/2 the height of the skirt part.

The utility model discloses has positive effect: the utility model discloses a structure sets up rationally, and it has seted up waist shape lightening hole on the face window to can wholly reduce the weight of piston, be favorable to reducing follow-up frictional force in the course of the work, reduce its wearing and tearing, thereby improve life, and can not influence the normal use of whole piston, use reliable and stable, the suitability is strong and the practicality is good.
