Force amplifier capable of generating axial displacement and axial thrust through rotation

Abstract

The invention discloses a force amplifying mechanism capable of generating axial displacement and axial thrust through rotation. The force amplifying mechanism comprises a piston and a gear ring, the piston and the gear ring are oppositely arranged, the top of the gear ring is close to the bottom of the piston, a plurality of spiral rising ball channels are annularly distributed between the piston and the gear ring, and steel balls are arranged in the spiral rising ball channels. According to the invention, small rotation torque can be converted into large axial thrust and axial displacement through the gear and the spiral ball groove structure, and the generated axial displacement and thrust can be adjusted.

Description

A booster mechanism that rotates to generate axial displacement and axial thrust technical field The invention belongs to the technical field of automobile braking, more specifically relate to a kind of rotation to produce axial displacement and axial displacement thrust booster. Background technique Most of the brakes on the market are traditional pneumatic drum brakes, and it is easy to enter foreign objects in a muddy environment and cause the braking effect. Poor or malfunctioning, it is also easy to damage the braking device, long-term braking will cause wear and tear, and the failure rate is high. Wet brake tightness It has strong anti-pollution ability and large structural rigidity, and is widely used. But existing wet brakes will have less turning force The moment shaft shift is transformed into a large thrust force and a complex structure in the axial position. Therefore, how to provide a booster mechanism that rotates to generate axial displacement and ...

AI Technical Summary

Problems solved by technology

However, the existing wet brakes have a complex structure that converts small rotational torque shaft displacement into large axial thrust and axial position.
