The engagement of interlocking teeth or dogs, as opposed to friction, is how a dog clutch (also known as a positive clutch or dog gears) connects two rotating shafts or other spinning components.
The clutch’s two components are made to push against one another, rotating at the same speed and never slipping. A “dog” is a tool or equipment used in engineering to lock two components in relation to one another.
Where slip is undesirable and/or the clutch is not used to control torque, dog clutches are employed. Dog clutch actuators do not experience wear in the same manner as friction clutches do without slippage, but when shafts of various speeds are engaged, they produce shock.
They are therefore most effective when the system’s inertia is low and quick starting action is acceptable.
In constant-mesh manual gearboxes, different gears are locked to spinning input and output shafts via dog clutches. By synchronizing the shaft speeds before allowing the dog clutch to contact, a synchromesh arrangement assures a smooth engagement.
Due to their high strength, durability, simplicity, and lack of complexity, dog clutches are frequently used by racecars, motorcycles, and large truck transmissions to engage gears without the use of synchronizers.
These transmissions have higher performance requirements than passenger cars and less need for smooth engagement. Clutchless shifting is possible with these dog boxes—unsynchronized gearboxes.
In synchromesh and constant mesh gearboxes, dog clutches or splined clutches are employed. On the side face of these clutches are teeth that only engage when two sets of teeth properly line up.
The dog clutch actuator comprises side protrusions (teeth) that are evenly spaced and mesh with a gear’s matching recess. Dog teeth are the name for these teeth.
The Global dog clutch actuator market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
Due to the tight lockdowns and social seclusion used to stop the COVID-19 virus’s spread, the automotive clutch market suffered as a result. The demand for the dog clutch actuator market was hampered by the uncertain economy, a temporary corporate shutdown, and poor consumer confidence.
During the epidemic, the supply chain was impeded along with logistics operations. Due to the loosening of the restrictions, the clutch market is anticipated to pick up during the post-pandemic environment.
