High-efficient Electromagnetic Dog Clutch System for EV/PHEV

Technology or product features/functions/usages; Innovation/uniqueness (list 2-3 key points); Power switching can be accomplished quickly and smoothly with a claw clutch actuated by an electromagnetic actuator. The product can realize power combination/disconnection of power shaft, planetary row and differential in EV/PHEV powertrain. 1.Replaces previous electromechanical or hydraulic actuator solutions with electromagnetic solutions 2.Combined with the ECU and high-precision sensors, the motion of the engaging parts can be precisely controlled, realizing fast and smooth engagement. 3.Extremely low stall hold power consumption and zero energy consumption for disengagement reset. Advantages/advancement over similar technologies/products; Value to customers/impact on or importance to the industry Flexible layout to meet tight space requirements with minimum axial dimensions of 35 mm, and to cope with severe dimensional constraints. Splined dog tooth design for both axial movement guidance and torque transmission. Spline axial design with inverted taper ensures that there is no unintentional disengagement during bonding and reduces the bond holding current to 1A. High accuracy position sensor developed specifically for this product, with small size, high anti-interference capability and high accuracy. Intelligent electromagnetic claw clutches with spline engagement, developed by Hoerbiger and the first publish in China. With Hoerbiger's intelligent dog clutch, the motor, leading screw, fork and associated fasteners can be replaced by an electromagnetic coil. Overall space savings of up to 75%, weight savings of up to 80% and cost reductions of up to 50% can be achieved.At the same time, the solenoid coil only needs to be energised during the coupling operation and does not need to be energised during the uncoupling process to rely on the reset spring, which reduces energy consumption by up to 60% compared to the motor-screw solution.

Electromagnetic Dog Clutch System for Half Shaft Disconnect

Technology or product features/functions/usages; Innovation/uniqueness (list 2-3 key points); The electromagnetic dog clutch realizes the disengagement of the vehicle's half-axle, avoiding the non-power wheels from dragging the electric motor under 2WD working condition. Reduce energy consumption and increase mileage. The product is in the form of assembly parts, which can be directly assembled by customers. 1. Half Shaft disconnect 2. Assemble System 3.Adaptation to small axial spaces Advantages/advancement over similar technologies/products; Value to customers/impact on or importance to the industry, etc. The above info with the support of quantitative data is highly recommended. Flexible layout to meet tight space requirements.Can be externally mounted on the exterior of the drive housing to upgrade the functionality of the existing drive system with minimal modification. Splined dog tooth design for both axial movement guidance and torque transmission. Spline axial design with inverted taper ensures that there is no unintentional disengagement during bonding and reduces the bond holding current to 1A. High accuracy position sensor developed specifically for this product, with small size, high anti-interference capability and high accuracy. Provides an excellent low-cost range optimization solution for new energy 4WD models. The application of the half-shaft disconnecting mechanism allows the vehicle to increase its range by 9% under the same operating conditions.
