Product Description

The gear motor for the electric park brake (EPB) is designed and developed for designated customers. This is only the showcase. Besides selling standard products, ZHAOWEI can provide design, research and manufacture for customers based on their specific needs as well. With its benefits of small size, low noise level, high torque, quick response, and long service life, the EPB actuator made by ZHAOWEI has always been the ideal choice of manufacturer.

Product Introduction

Based on the analysis of the electric park brake system, we modify the gear tooth profile to make it respond in a short time and realize high torque under the large current. To achieve low noise and high torque with small volume, ZHAOWEI gear motor comes to reduce the impact of noise and vibration on the gear module performance.

Gearbox Design Introduction

With self-developed gear design platform which can design and automatically calculate the gear parameters and build simulation model of volute gear-pair, cone gear-pair and face gear-pair, ZHAOWEI has much experience in computer sided design.

Gear Tooth Profile Modification

ZHAOWEI gearbox design platform has a nice performance in gear modification coefficient, meshing angle calculation, gear slip ratio, contact and overlap ratio calibration. At the production development stage, it is helpful to improve the gearbox noise performance, make gearbox life time longer. 

Gearbox Dynamic Simulation and FEA

At the gear design review stage, the engineer will use the ZHAOWEI design platform to conduct design simulation and FEA to verify the design parameters and gear strength performance.
