3 results about "MacPherson strut" patented technology

This invention relates to a MacPherson strut suspension wheel-side drive system, comprising a transmission unit, a drive motor, a connecting mechanism, a sub-support, a frame, and a support bearing. The transmission unit includes a transmission mechanism housing and a transmission mechanism, which connects the drive motor and the wheel hub. The transmission mechanism housing and the connecting mechanism connect to the sub-support. The sub-support connects to the inner ring of the support bearing, and the frame connects to the outer ring of the support bearing. The axis of the support bearing is perpendicular to the axis of the wheel. The vertical line of the wheel's contact point with the ground is located within the radius of rotation of the support bearing. Compared with the prior art, this invention features a support bearing with a large radius of rotation arranged at the top of the sub-support, ensuring that the vertical line of the wheel's contact point with the ground is always within the radius of rotation of the support bearing. This satisfies the requirements for large-angle steering and reduces the support stiffness requirements of the overall structure. The torsion bar spring enhances the structural stiffness of the transmission unit, helping to reduce gear wear and noise.

This utility model discloses a range-extended electric vehicle (REEV) fueled by natural gas, belonging to the field of natural gas vehicle technology. It mainly includes a vehicle body and wheels. A front subframe is located at the front of the vehicle body, and a rear axle is located at the rear. A natural gas range extender is housed in the front compartment of the vehicle body and is suspended on the front subframe. The crankshaft of the range extender faces the same direction as the vehicle's travel. The front subframe is connected to the vehicle body and the front wheels via MacPherson strut suspension. A gas cylinder and a power battery are fixedly connected to the bottom of the vehicle body. The gas cylinder is connected to the range extender via pipelines. A drive motor is located on the rear axle, and the power battery powers the drive motor. This utility model converts the energy of natural gas into electrical energy, stores it in the power battery, and then uses it to drive the motor to propel the vehicle. It possesses the characteristics of good responsiveness and strong power of electric vehicles, fundamentally solving the shortcomings of low energy density and weak power of natural gas-fueled vehicles.

The utility model relates to an auxiliary mounting device for a brake and a shock absorber of a Macpherson structure. The auxiliary mounting device comprises an assembly table; the positioning mechanism is used for positioning and mounting the shock absorber; the limiting mechanism is used for limiting the brake in the circumferential direction and the axial direction of the brake; the anti-rotation mechanism is used for limiting the connecting piece to rotate in the circumferential direction of the connecting piece. The shock absorber is positioned and installed on the assembly table through the positioning mechanism, the shock absorber and the brake are rapidly aligned and connected through the connecting piece, the brake is limited in the circumferential direction and the axial direction of the brake through the limiting mechanism, and therefore the brake is prevented from rotating and turning over; when the shock absorber is connected with the brake, relative rotation between the connecting piece and the shock absorber or the brake can be limited. The auxiliary installation device for the brake and the shock absorber of the Macpherson type structure has the advantages of being simple in structure, easy and convenient to operate, low in equipment cost and short in design and manufacturing period, and therefore production and manufacturing cost is effectively reduced.
