Abstract

Disclosed is a novel distribution device of a motorcycle engine. A chain is connected between a driving timing gear and a driven gear timing gear; a front cam and a rear cam are coaxially installed on the rear side of the driven gear timing gear; a lower air inlet swing arm and a lower air exhaust swing arm both in L-shaped structures are respectively hinged on a supporting point at the corner position; the lower end of the lower air inlet swing arm is hinged with the front cam; the upper end of the lower air inlet swing arm is hinged with the lower end of an air inlet roof bar; the upper end of the air inlet roof bar is connected with the inner end of an air inlet swing arm; the outer end of the air inlet swing arm is connected with an air inlet valve adjusting screw nail; the lower end of the lower air exhaust swing arm is hinged with the rear cam; the upper end of the lower air exhaust swing arm is hinged with the lower end of the roof bar; the upper end of the roof bar is connected with the inner end of the an air exhaust swing arm; and the outer end of the air exhaust swing arm is connected with an exhaust valve adjusting screw nail. The novel distribution device solves the problems that an existing similar device is large in noise, slow in speed acceleration, low in power, large in vibration and starting resistance, easily worn at the position of a tensile wheel, low in air inlet efficiency, small in torque and high in cylinder temperature rise.

Description

The novel distribution device of motorcycle engine

Technical field

The utility model relates to the distribution device of motorcycle engine.

Background technique

At present, GG Engine Series distribution device has following dual mode: a kind of is single cam, the helical teeth transmission, and this distribution device exists noise big, and speed-raising is slow, and vibrations are big, and the resistance of start is big, the shortcoming that the cylinder intensification is high; Another is single cam, chain transmission, push rod intersection, upper rocker arm and push rod abutting end lengthening, and tension device is the rolling wheel, and this mechanism is low at intake efficiency, underpower, and moment of torsion is little, and Idle wheel is the shortcoming of wearing and tearing easily.

The model utility content

The purpose of this utility model provides the novel distribution device of a kind of motorcycle engine, and the utility model has solved the problem that noise is big, speed-raising is slow, power is low, vibrations are big, the resistance of start is big, tension bar is worn and torn easily, intake efficiency is low, moment of torsion is little, the cylinder temperature rise is fast that existing same device exists.

The novel distribution device of motorcycle engine of the present utility model comprises intake rocker, air inlet push rod, following intake rocker, front cam, follower timing gear, driving wheel timing gear, exhaust rocker arm, exhaust push rod, following exhaust rocker arm, back cam; Be connected chain between driving wheel timing gear and the follower timing gear; Rear side at the follower timing gear is coaxially installed with front cam and back cam; Following intake rocker and following exhaust rocker arm are L type structure, and following intake rocker and following exhaust rocker arm are hinged on the strong point respectively around the corner; Following intake rocker lower end and front cam are hinged, and the lower end of the upper end of following intake rocker and air inlet push rod is hinged, and air inlet push rod upper end connects the inner of intake rocker, and the outer end of intake rocker is connected with the intake valve adjusting screw; Following exhaust rocker arm lower end is hinged with the back cam; Following exhaust rocker arm upper end is hinged with the push rod lower end, and the push rod upper end connects the inner of exhaust rocker arm, and the outer end of exhaust rocker arm connects the exhaust valve adjusting screw.

In the left side of chain 7 the chain gib block is installed, have by hinged point-supported tension bar on the chain right side, the middle part of tension arms is by the hinged support of tension arms supporting screw, and the tension arms upper end holds out against on tension bar, the other end of tension arms connects nutted rod, and nutted rod connects tension spring.

The novel distribution device of motorcycle engine of the present utility model, it is little to have a noise, and speed-raising is fast, and power is big, shakes for a short time, and the resistance of start is little, and tension bar is not easy to wear, the intake efficiency height, moment of torsion is big, the advantage that cylinder temperature is low.

Description of drawings

Fig. 1 is the utility model structural representation.

Embodiment

Below in conjunction with accompanying drawing and with illustrated embodiments the utility model is done detailed explanation.
