Gearbox energy accumulator

How do accumulators work?

Accumulators and their circuits have been used for years as the primary method for controlling shift feel. These components are designed to modify a shift by essentially acting as a shock absorber for the fluid pressure that is applying a clutch, brake or band.

What is the function of accumulator in a transmission?

The accumulators allow the supply of hydraulic oil to the moving components of the transmission, which are essential for the gear´s start - stop function. The accumulator fills with oil while driving, leaving a reserve for when the engine is started, at which time this reserve is returned to the hydraulic system to supply oil to the shift elements.

How do accumulators store energy?

In many situations, accumulators can be used to store energy during motoring quadrants, i.e., when energy flows from the load into the hydraulic circuit. In one case scenario, accumulators can store energy from several hydraulic actuators and/or motors through a common pressure rail (CPR) system.

What are the uses of gas-loaded accumulators in hydraulic circuits?

In the following sections, we describe typical uses of gas-loaded accumulators in hydraulic circuits as energy storage components. In many situations, accumulators can be used to store energy during motoring quadrants, i.e., when energy flows from the load into the hydraulic circuit.

Where can I find spare parts for a hydraulic transmission accumulator?

If after taking your vehicle to the mechanic they noticed that there is a fault with the transmission accumulator, in the SUN Transmissions online store you will find spare parts for hydraulic transmissions, such as pistons, valves, repair kits and many others that we invite you to discover by browsing the website.

Do You need A accumulator in a 6-speed transmission?

In many newer 6- and 8-speed transmissions, “traditional” accumulators and related valves are no longer needed. That’s because the computer and solenoids have direct control over the shifts, providing very fine control of shift feel, often in clutch-to-clutch transitions.
