3results about How to "Overcome spring force" patented technology

The invention relates to a method for producing a pedal device (10) for a drive-by-wire system of a vehicle, in which a pedal part (50) is mounted on a support structure (20) in such a way that first a bearing section (LA) of the pedal part (50) is brought into contact with a bearing region (LB) of a first support part (22) of the support structure (20), and second support part (22) of the support structure (20) is brought into contact with a bearing region (LB) of a second support part (22) of the support structure (20). And subsequently mounting a second support part (24) of the support structure (24) on the first support part (22) in such a way that the bearing section (LA) of the pedal part (50) is loaded towards the bearing region (LB) of the first support part (22). The invention further relates to a pedal device for the drive-by-wire system.

A snowplow transmission clutch assembly belongs to the field of snowplow technology. It utilizes spring pressure to engage friction blocks planarly, resulting in a large contact area, smooth engagement, and the ability to transmit significant torque. It also provides overload protection through friction slippage. A traction cable directly overcomes the spring force, quickly pulling the active friction block back for complete power separation and rapid response. The entire assembly is integrated between the fixed shaft and the input shaft, resulting in a compact structure. The single traction cable with a dual-branch layout ensures balanced force on the sliding shaft, smooth operation, and convenient control via a remote cable. The friction blocks are connected via dovetail grooves, facilitating easy replacement after wear and reducing maintenance costs and time.

This invention relates to the field of bearing testing technology, specifically to a bearing assembly testing device and method. The device includes a testing base with a testing fixture rotatably connected to it for fixing the bearing. A vibration detector is mounted on the testing base, with one end of the detector contacting the bearing surface. The invention utilizes an adjustment assembly with three positioning rods and contact blocks on a slide. Pushing the slide allows the contact blocks to apply an axial load to one end of the bearing for initial testing. To test the other side, the contact blocks are retracted using the adjustment assembly, the slide is pushed past the bearing to reach the other side, and then the contact blocks are extended again and the slide is pulled back to apply a reverse load. This design, by applying pressure to both sides of the bearing using the same loading mechanism, completely eliminates the blind spot caused by unilateral loading, ensuring consistency between the two testing conditions. Furthermore, it eliminates the need to disassemble the bearing, significantly improving the comprehensiveness, reliability, and efficiency of the testing.
